First part for #6498 - refactoring of the upload infrastructure, in preparation for `update_database_table`.
Implemented a `Set` data structure which was long needed.
The APIs are added and an initial implementation is created, but it is not complete - but it has grown significantly already so the remaining implementation will be done as a separate PR.
Adds some basic ability for a function to ensure that it is only executed from within a transaction.
- Add the missing dropdowns for `Locale` and `Encoding`.
- Correct a few mismatched type signatures.
- Adjust `order_by` calls with a single `Sort_Column` to call in a Vector.
- Adjust parameter names for `transpose`.
- Fix for the table viz: escape HTML and `suppressFieldDotNotation`.
- Use `Filter_Condition.Equal True` for the default filter.
- Adjust `Data.fetch` to return the response on success when parse fails. Rename `parse` to `try_auto_parse`.
- Add various aliases for methods.
- Add tests for `Table.set` when using a `Vector`, `Range` or `Date_Range`.
- Add check for mismatched length on `Table.set`.
Previously, a `RuntimeException` would be thrown when an attempt would be made to curry a conversion function. That is problematic for IDE where `executionFailed` means we can't enter functions due to lack of method pointers info.
Closes#6897.
# Important Notes
A more generic solution that allows to recover from execution failures will need a follow up.
Closes#5227
# Important Notes
- This lays first steps towards #6292 - we get pure Enso variants of MultiValueKey.
- Another part refactors `LongStorage` into `AbstractLongStorage` allowing it to provide alternative implementations of the underlying storage, in our case `LongRangeStorage` generating the values ad-hoc and `LongConstantStorage` - currently unused but in the future it can be adapted to support constant columns (once we implement similar facilities for other types).
- Adds execution control to `Table.write`.
- Refactored the `Text.write` to make part reusable.
- Tidied up some legacy mess in tests.
- Add easier flow to go from `Text` to an `URI` to fetching data.
- Add decode functions to `Response` and `Response_Body`.
- Fix issue with 0 length regex matches (using same as Python and .Net approach).
- Add various ALIAS entries to make function discovery easier.
- Sort a lot of drop down and vector editors out (including switch to fully qualified names).
Throwing `TailCallException` meant that exceptions that were extracted from the expression before the call was made could not be appended. This change catches the `TailCallException`, adds warnings to it and propagates it further, thus ensuring that we don't loose the information.
Closes#6765.
# Important Notes
Removed workarounds introduced in stdlib.
- Fix couple of bugs in Table viz: rounding of bottom div, missing character, not including row count as an option.
- Add better JSON format for `Row`, add support for visualization in the Table viz both for `Vector Row` or `Row`.
- Fix some type signature errors.
- Move `Column_Format` to `Standard.Table.Internal`.
- Move `format_widget` to `File_Format.default_widget` and sort the signature of `Widget` methods.
- Added utility to make `Single_Choice` widgets.
- Added dropdown for delimiter on split methods.
- Removed `default_widget` from `Problem_Behavior` and `Filter_Condition`.
- Altered signature and widgets for table functions.
- Added `to_column` extension to allow easy conversion of Range and Vector to Column.
- Added `compute`, `compute_bulk`, `running` to Column to allow statistic computation.
- Added drop down for `Table.write` format parameter.
- Added drop down for `Table.rename_columns`.
- Added support for Vector of pairs for renaming columns.
- Added check when making a map from Vector if not 2 items.
Implements the simplest `parse` scenarios for the Database backend.
Before #6711 these could have been done by `cast`, but in #6711 the APIs were unified to only allow casting to the same set of types in both in-memory and Database. Converting Text to other types is supposed to be done by `parse` and not `cast`, so the ability to use `cast` for rudimentary parsing is removed in the Database backend to make it consistent with in-memory. But now it is lacking any, even simplest, Text->Int/Text->Date support. To alleviate that, the simple scenarios for `parse` are implemented (no support for format customization yet, will boil down to a cast under the hood).
close#6611
Changelog:
- update: run compiler passes on the `ascribedType` field of the constructor arguments
- update: suggestion builder uses the type information attached to `ascribedType`
- feat: resolve qualified names in type signatures
- Moved the row count out of the grid.
- Shown for all cases.
- Added some of the JS wiring to do pages but currently hidden.
- Dropdown allowing the user to control the number of rows rendered.
- `Nothing` rendered as a italic light Nothing not just empty now.
- Function rendered as `[Function]`.
- Rounded corners on top to make it align more with look of panel.
- Dropdown for `Text.split` delimiter feed.
Related to #6410
# Important Notes
- Updated some `Meta` methods (needed for error handling):
- `Meta.Type` now has `name` and `qualified_name`.
- `Meta.Constructor` has `declaring_type` allowing to get the type that this constructor is associated with.
Fixes#6609 by
- e380e647af - running whole `Vector_Spec` on `java.util.ArrayList`
- 9b1229fe20 - introducing a node to handle interop values
# Important Notes
Contains additional DSL processor fix:
- 415623dcb9 - to not crash the compiler, but to properly report compiler error
Artifically limiting the number of reported warnings to 100. Also added benchmarks with random Ints to investigate perf issues when dealing with warnings (future task).
Ideally we would have a custom set-like collection that allows us internally to specify a maximal number of elements. But `EnsoHashMap` (and potentially `EnsoSet`) are still WIP when it comes to being PE-friendly.
The change also allows for checking if the limit for the number of reported warnings has been reached. It will visualize by adding an additional "Warnings limit reached." to the visualization.
The limit is configurable via `--warnings-limit` parameter to `run`.
Closes#6283.
Closes#6437
Related to #6410
- Add example duplicate row to `Non_Unique_Primary_Key`.
- Ensure `File.read` fails if the file does not exist, always.
- Ensure SQLite fails if file is empty or nonexistent or malformed.
- Split file format detection into read and write modes, so that the read mode can depend on actual file _contents_.
When generating new column names in tokenize/split_to_columns, if there's only one new column, use the deleted input column name and don't add disambiguating integers after it.
Add format to the in-memory Column
# Important Notes
Also updates .format in date types.
Some rearrangement of date formatting builtins / Java libraries.
- Add dropdown to tokenize and split `column`.
- Remove the custom `Join_Kind` dropdown.
- Adjust split and tokenize names to start numbering from 1, not 0.
- Add JS_Object serialization for Period.
- Add `days_until` and `until` to `Date`.
- Add `Date_Period.Day` and create `next` and `previous` on `Date`.
- Use simple names with `File_Format` dropdown.
- Avoid using `Main.enso` based imports in `Standard.Base.Data.Map` and `Standard.Base.Data.Text.Helpers`.
- Remove an incorrect import from `Standard.Database.Data.Table`.
From #6587:
A few small changes, lots of lines because this affected lots of tests:
- `Table.join` now defaults to `Join_Kind.Left_Outer`, to avoid losing rows in the left table unexpectedly. If the user really wants to have an Inner join, they can switch to it.
- `Table.join` now defaults to joining columns by name not by index - it looks in the right table for a column with the same name as the first column in left table.
- Missing Input Column errors now specify which table they refer to in the join.
- The unique name suffix in column renaming / default column names when loading from file is now a space instead of underscore.
- Add `with_disabled` shortcut for `Context`.
- Protect `Image.write` behind `Context.Output`.
- Correct text on the `Forbidden_Operation` error message.
- Remove context overrides from tests.
- Add `File` operations tests with `Context.Output` disabled.
- Add tests for `Text.write` operations with `Context.Output` disabled.
- Use a better method to make `File_Format` dropdown widget.
- Fix bug in `Invalid_Format.to_display_text`.
Remove the magical code generation of `enso_project` method from codegen phase and reimplement it as a proper builtin method.
The old behavior of `enso_project` was special, and violated the language semantics (regarding the `self` argument):
- It was implicitly declared in every module, so it could be called without a self argument.
- It can be called with explicit module as self argument, e.g. `Base.enso_project`, or `Visualizations.enso_project`.
Let's avoid implicit methods on modules and let's be explicit. Let's reimplement the `enso_project` as a builtin method. To comply with the language semantics, we will have to change the signature a bit:
- `enso_project` is a static method in the `Standard.Base.Meta.Enso_Project` module.
- It takes an optional `project` argument (instead of taking it as an explicit self argument).
Having the `enso_project` defined as a (shadowed) builtin method, we will automatically have suggestions created for it.
# Important Notes
- Truffle nodes are no longer generated in codegen phase for the `enso_project` method. It is a standard builtin now.
- The minimal import to use `enso_project` is now `from Standard.Base.Meta.Enso_Project import enso_project`.
- Tested implicitly by `org.enso.compiler.ExecCompilerTest#testInvalidEnsoProjectRef`.
- Adjusted `Context.is_enabled` to support default argument (moved built in so can have defaults).
- Made `environment` case-insensitive.
- Bug fix for play button.
- Short hand to execute within an enabled context.
- Forbid file writing if the Output context is disabled with a `Forbidden_Operation` error.
- Add temporary file support via `File.create_temporary_file` which is deleted on exit of JVM.
- Execution Context first pass in `Text.write`.
- Added dry run warning.
- Writes to a temporary file if disabled.
- Created a `DryRunFileManager` which will create and manage the temporary files.
- Added `format` dropdown to `File.read` and `Data.read`.
- Renamed `JSON_File` to `JSON_Format` to be consistent.
(still to unit test).
This change modifies method dispatch for methods that override Any's definitions. When an overrided method is invoked statically we call Any's method to stay consistent.
This change primarily addresses the plethora of problems related to `to_text` invocations. It does not attempt to completely modify method dispatch logic.

`Number.nan` can be used as a key in `Map`. This PR basically implements the support for [JavaScript's Same Value Zero Equality](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Equality_comparisons_and_sameness#same-value-zero_equality) so that `Number.nan` can be used as a key in `Map`.
# Important Notes
- For NaN, it holds that `Meta.is_same_object Number.nan Number.nan`, and `Number.nan != Number.nan` - inspired by JS spec.
- `Meta.is_same_object x y` implies `Any.== x y`, except for `Number.nan`.
https://github.com/orgs/enso-org/discussions/6344 requested to change the order of arguments when controlling context permissions.
# Important Notes
The change brings it closer to the design doc but IMHO also a bit cumbersome to use (see changed tests) - applications involving default arguments don't play well when the last argument is not the default 🤷 .`

The primary motivation for this change was
https://github.com/enso-org/enso/issues/6248, which requested the possibility of defining `to_display_text` methods of common errors via regular method definitions. Until now one could only define them via builtins.
To be able to support that, polyglot invocation had to report `to_display_text` in the list of (invokable) members, which it didn't. Until now, it only considered fields of constructors and builtin methods. That is now fixed as indicated by the change in `Atom`.
Closes#6248.
# Important Notes
Once most of builtins have been translated to regular Enso code, it became apparent how the usage of `.` at the end of the message is not consistent and inflexible. The pure message should never follow with a dot or it makes it impossible to pretty print consistently for the purpose of error reporting. Otherwise we regularly end up with errors ending with `..` or worse. So I went medieval on the reasons for failures and removed all the dots.
The overall result is mostly the same except now we are much more consistent.
Finally, there was a bit of a good reason for using builtins as it simplified our testing.
Take for example `No_Such_Method.Error`. If we do not import `Errors.Common` module we only rely on builtin error types. The type obviously has the constructor but it **does not have** `to_display_text` in scope; the latter is no longer a builtin method but a regular method. This is not really a problem for users who will always import stdlib but our tests often don't. Hence the number of changes and sometimes lack of human-readable errors there.
Closes#5254
In #6189 the SQLite version was bumped to a newer release which has builtin support for Full and Right joins, so no workaround is no longer needed.
As per design, IOContexts controlled via type signatures are going away. They are replaced by explicit `Context.if_enabled` runtime checks that will be added to particular method implementations.
`production`/`development` `IOPermissions` are replaced with `live` and `design` execution enviornment. Currently, the `live` env has a hardcoded list of allowed contexts i.e. `Input` and `Output`.
# Important Notes
As per design PR-55. Closes#6129. Closes#6131.
close#6080
Changelog
- add: implement `SuggestionsRepo.insertAll` as a batch SQL insert
- update: `search/getSuggestionsDatabase` returns empty suggestions. Currently, the method is only used at startup and returns the empty response anyway because the libs are not loaded at that point.
- update: serialize only global (defined in the module scope) suggestions during the distribution building. There's no sense in storing the local library suggestions.
- update: sqlite dependency
- remove: unused methods from `SuggestionsRepo`
- remove: Arguments table
# Important Notes
Speeds up libraries loading by ~1 second.
Implements #6134.
# Important Notes
One can define lazy atom fields as:
```haskell
type Lazy
Value ~x ~y
```
the evaluation of the `x` and `y` fields is then delayed until they are needed. The evaluation happens once. Then the computed value is kept in the atom for further use.
Fixes#5898 by removing `Catch.panic` and speeding the `sieve.enso` benchmark from 1058 ms to 514 ms. Should there be no dedicated conversion, let's use one defined on `Any` type - e.g. defining a conversion `from(Any)` makes such a conversion is always available.
- `Process.run` now returns a `Process_Result` allowing the easy capture of stdout and stderr.
- Joining a column with a column name does not warn if adding just the prefix.
- Stop the table viz from changing case and adding spaces to the headers.
This is the first part of the #5158 umbrella task. It closes#5158, follow-up tasks are listed as a comment in the issue.
- Updates all prototype methods dealing with `Value_Type` with a proper implementation.
- Adds a more precise mapping from in-memory storage to `Value_Type`.
- Adds a dialect-dependent mapping between `SQL_Type` and `Value_Type`.
- Removes obsolete methods and constants on `SQL_Type` that were not portable.
- Ensures that in the Database backend, operation results are computed based on what the Database is meaning to return (by asking the Database about expected types of each operation).
- But also ensures that the result types are sane.
- While SQLite does not officially support a BOOLEAN affinity, we add a set of type overrides to our operations to ensure that Boolean operations will return Boolean values and will not be changed to integers as SQLite would suggest.
- Some methods in SQLite fallback to a NUMERIC affinity unnecessarily, so stuff like `max(text, text)` will keep the `text` type instead of falling back to numeric as SQLite would suggest.
- Adds ability to use custom fetch / builder logic for various types, so that we can support vendor specific types (for example, Postgres dates).
# Important Notes
- There are some TODOs left in the code. I'm still aligning follow-up tasks - once done I will try to add references to relevant tasks in them.
Enables `distinct`, `aggregate` and `cross_tab` to use the Enso hashing and equality operations.
Also, I rewired the way the ObjectComparators are obtained in polyglot code to be more consistent.
Add Comparator for `Day_Of_Week`, `Header`, `SQL_Type`, `Image` and `Matrix`.
Also, removed the custom `==` from these types as needed. (Closes#5626)
- Fixes InvokeCallableNode to support warnings.
- Strips warnings from annotations in `get_widget_json`.
- Remove `get_full_annotations_json`.
- Fix warnings on Dialect.
Exporting types named the same as the module where they are defined in `Main` modules of library components may lead to accidental name conflicts. This became apparent when trying to access `Problem_Behavior` module via a fully qualified name and the compiler rejected it. This is due to the fact that `Main` module exported `Error` type defined in `Standard.Base.Error` module, thus making it impossible to access any other submodules of `Standard.Base.Error` via a fully qualified name.
This change adds a warning to FullyQualifiedNames pass that detects any such future problems.
While only `Error` module was affected, it was widely used in the stdlib, hence the number of changes.
Closes#5902.
# Important Notes
I left out the potential conflict in micro-distribution, thus ensuring we actually detect and report the warning.
Fixing #5768 and #5765 and co. Introducing `Meta.Type` and giving it the desired methods.
# Important Notes
`Type` is no longer a `Meta.Atom`, but it has a dedicated `Meta.Type` representation.
Implement new Enso documentation parser; remove old Scala Enso parser.
Performance: Total time parsing documentation is now ~2ms.
# Important Notes
- Doc parsing is now done only in the frontend.
- Some engine tests had never been switched to the new parser. We should investigate tests that don't pass after the switch: #5894.
- The option to run the old searcher has been removed, as it is obsolete and was already broken before this (see #5909).
- Some interfaces used only by the old searcher have been removed.
Closes#5151 and adds some additional tests for `cross_tab` that verify duplicated and invalid names.
I decided that for empty or `Nothing` names, instead of replacing them with `Column` and implicitly losing connection with the value that was in the column, we should just error on such values.
To make handling of these easier, `fill_empty` was added allowing to easily replace the empty values with something else.
Also, `{is,fill}_missing` was renamed to `{is,fill}_nothing` to align with `Filter_Condition.Is_Nothing`.
Merge _ordered_ and _unordered_ comparators into a single one.
# Important Notes
Comparator is now required to have only `compare` method:
```
type Comparator
comapre : T -> T -> (Ordering|Nothing)
hash : T -> Integer
```
Follow-up to #5113 - I add some more edge case tests as we discussed with @jdunkerley
When debugging some quoting issues, I also realised the current `Mismatched_Quote` error provided not enough information. So I amended it to at least include some context indicating which was the 'offending' cell.
Removing special handling of `AtomConstructor` in `Meta.is_a` check.
# Important Notes
A lot of tests are about to fail. Many of them indirectly call `Meta.is_a` with a constructor rather than type.
- Fix issue with Geo Map viz.
- Handle invalid format strings better in `Data_Formatter`.
- New constants for the ISO format strings (and a special ENSO_ZONED_DATE_TIME)
- Consistent Date Time format for parsing in all places.

- Support for milliseconds (well nanoseconds) in Date_Time and Time_Of_Day.
- `Column.map` stays within Enso.
- Allow `Aggregate_Column.Group_By` in `cross_tab` group_by parameter.
Closes#5113
Fixes a bug where read-only files would be overwritten if File.write was used in backup mode, and added tests to avoid such regression. To implement it, introduced a `is_writable` property on `File`.
- Adjust Excel Workbook write behaviour.
- Support Nothing / Null constants.
- Deduce the type of arithmetic operations and `iif`.
- Allow Date_Time constants, treating as local timezone.
- Removed the `to_column_name` and `ensure_sane_name` code.

- Updates the `rename_columns` API.
- Add `first_row`, `second_row` and `last_row` to the Table types.
- New option for reading only last row of ResultSet.
Rename is_match + match to match + find (respectively), and remove all non-regexp functionality.
Regexp flags and Match_Mode are also no longer supported by these methods.
Critical performance improvements after #4067
# Important Notes
- Replace if-then-else expressions in `Any.==` with case expressions.
- Fix caching in `EqualsNode`.
- This includes fixing specializations, along with fallback guard.
Remove regex support from .locate and .locate_all; regex functionality is moved to .match and .match_all where appropriate. This is in preparation for simplifying regex support across the board.
Also change Matching_Mode types to a single type with two variants.
Note: the matcher parameter to .locate and .locate_all has been replaced by a case_sensitivity parameter, of type Case_Sensitivity, which differs in that it also has a Default option. Default is treated as Sensitive.
- Updated `Widget.Vector_Editor` ready for use by IDE team.
- Added `get` to `Row` to make API more aligned.
- Added `first_column`, `second_column` and `last_column` to `Table` APIs.
- Adjusted `Column_Selector` and associated methods to have simpler API.
- Removed `Column` from `Aggregate_Column` constructors.
- Added new `Excel_Workbook` type and added to `Excel_Section`.
- Added new `SQLiteFormatSPI` and `SQLite_Format`.
- Added new `IamgeFormatSPI` and `Image_Format`.
Closes#5109
# Important Notes
- Currently the tests pass for the in-memory parts of Common_Table_Operations, but still some stuff not working on DB backends - in progress.
Add `Comparator` type class emulation for all types. Migrate all the types in stdlib to this new `Comparator` API. The main documentation is in `Ordering.enso`.
Fixes these pivotals:
- https://www.pivotaltracker.com/story/show/183945328
- https://www.pivotaltracker.com/story/show/183958734
- https://www.pivotaltracker.com/story/show/184380208
# Important Notes
- The new Comparator API forces users to specify both `equals` and `hash` methods on their custom comparators.
- All the `compare_to` overrides were replaced by definition of a custom _ordered_ comparator.
- All the call sites of `x.compare_to y` method were replaced with `Ordering.compare x y`.
- `Ordering.compare` is essentially a shortcut for `Comparable.from x . compare x y`.
- The default comparator for `Any` is `Default_Unordered_Comparator`, which just forwards to the builtin `EqualsNode` and `HashCodeNode` nodes.
- For `x`, one can get its hash with `Comparable.from x . hash x`.
- This makes `hash` as _hidden_ as possible. There are no other public methods to get a hash code of an object.
- Comparing `x` and `y` can be done either by `Ordering.compare x y` or `Comparable.from x . compare x y` instead of `x.compare_to y`.
- Fixes the display of Date, Time_Of_Day and Date_Time so doesn't wrap.
- Adjust serialization of large integer values for JS and display within table.
- Workaround for issue with using `.lines` in the Table (new bug filed).
- Disabled warning on no specified `separator` on `Concatenate`.
Does not include fix for aggregation on integer values outside of `long` range.
Closes#5038
- Use the proper widget structure.
- Provide new method `get_widget_json` with whole structure, but keep `get_full_annotations_json` in old form.
- Start to get to some reusable functions.
- Added widget to JS_Object field selections.
- New `set` function design - takes a `Column` and works with that more easily and supports control of `Set_Mode`.
- New simple `parse` API on `Column`.
- Separated expression support for `filter` to new `filter_by_expression` on `Table`.
- New `compute` function allowing creation of a column from an expression.
- Added case sensitivity argument to `Column` based on `starts_with`, `ends_with` and `contains`.
- Added case sensitivity argument to `Filter_Condition` for `Starts_With`, `Ends_With`, `Contains` and `Not_Contains`.
- Fixed the issue in JS Table visualisation where JavaScript date was incorrectly set.
- Some dynamic dropdown expressions - experimenting with ways to use them.
- Fixed issue with `.pretty` that wasn't escaping `\`.
- Changed default Postgres DB to `postgres`.
- Fixed SQLite support for starts_with, ends_with and contains to be consistent (using GLOB not LIKE).
- Updated `Text.starts_with`, `Text.ends_with` and `Text.contains` to new simpler API.
- Added a `Case_Sensitivity.Default` and adjusted `Table.distinct` to use it by default.
- Fixed a bug with `Data.fetch` on an HTTP error.
- Improved SQLite Case Sensitivity control in distinct to use collations.
When the function is visualized with the `default_preprocessor` method, it returns a dataflow error that shows up in the logs as
```
Cannot encode class org.enso.interpreter.runtime.error.DataflowError to byte array.
```
PR handles dataflow errors in the preprocessor and fallbacks the `to_display_text` value. As a bonus, we get a function visualization.

# Important Notes
* the best laziness is used for `Text` type, which makes use of its internal representation to send data
* any type will first compute its default string representation and then send the content of that lazy to the IDE
* special handling of files and their content will be implemented in the future
* size of the displayed text can be updated dynamically based on best effort information: if the backend does not yet know the full width/height of the text, it can update the IDE at any time and this will be handled gracefully by updating the scrollbar position and sizes.

# Important Notes
- Since now the only operator on columns for division, `/`, returns floats, it may be worth creating an additional `div` operator exposing integer division. But that will be done as a separate task aligning column operator APIs.
Use `InteropLibrary.isString` and `asString` to convert any string value to `byte[]`
# Important Notes
Also contains a support for `Metadata.assertInCode` to help locating the right place in the code snippets.
**Vector**
- Adjusted `Vector.sort` to be `Vector.sort order on by`.
- Adjusted other sort to use `order` for direction argument.
- Added `insert`, `remove`, `index_of` and `last_index_of` to `Vector`.
- Added `start` and `if_missing` arguments to `find` on `Vector`, and adjusted default is `Not_Found` error.
- Added type checking to `+` on `Vector`.
- Altered `first`, `second` and `last` to error with `Index_Out_Of_Bounds` on `Vector`.
- Removed `sum`, `exists`, `head`, `init`, `tail`, `rest`, `append`, `prepend` from `Vector`.
**Pair**
- Added `last`, `any`, `all`, `contains`, `find`, `index_of`, `last_index_of`, `reverse`, `each`, `fold` and `reduce` to `Pair`.
- Added `get` to `Pair`.
**Range**
- Added `first`, `second`, `index_of`, `last_index_of`, `reverse` and `reduce` to `Range`.
- Added `at` and `get` to `Range`.
- Added `start` and `if_missing` arguments to `find` on `Range`.

- Adjusted `Aggregate_Column` to operate on the first column by default.
- Added `contains_key` to `Map`.
- Added ALIAS to `row_count` and `order_by`.
Don't propagate errors from `toDisplayString` - construct an error message with `Atom.toString`.
# Important Notes
> currently a failure in to_text is swallowed by `toString` and we cannot detect that something went wrong during the serialization
Not sure how satisfying the solution is, but the error swallowing happens in Truffle and there is little to do with it. We can just catch the error ourselves and produce some meaningful string.
Most of the problems with accessing `ArrayOverBuffer` have been resolved by using `CoerceArrayNode` (https://github.com/enso-org/enso/pull/3817). In `Array.sort` we still however specialized on Array which wasn't compatible with `ArrayOverBuffer`. Similarly sorting JS or Python arrays wouldn't work.
Added a specialization to `Array.sort` to deal with that case. A generic specialization (with `hasArrayElements`) not only handles `ArrayOverBuffer` but also polyglot arrays coming from JS or Python. We could have an additional specialization for `ArrayOverBuffer` only (removed in the last commit) that returns `ArrayOverBuffer` rather than `Array` although that adds additional complexity which so far is unnecessary.
Also fixed an example in `Array.enso` by providing a default argument.
Compiler performed name resolution of literals in type signatures but would silently fail to report any problems.
This meant that wrong names or forgotten imports would sneak in to stdlib.
This change introduces 2 main changes:
1) failed name resolutions are appended in `TypeNames` pass
2) `GatherDiagnostics` pass also collects and reports failures from type
signatures IR
Updated stdlib so that it passes given the correct gatekeepers in place.
Implements https://www.pivotaltracker.com/story/show/184032869
# Important Notes
- Currently we get failures in Full joins on Postgres which show a more serious problem - amending equality to ensure that `[NULL = NULL] == True` breaks hash/merge based indexing - so such joins will be extremely inefficient. All our joins currently rely on this notion of equality which will mean all of our DB joins will be extremely inefficient.
- We need to find a solution that will support nulls and still work OK with indices (but after exploring a few approaches: `COALESCE(a = b, a IS NULL AND b is NULL)`, `a IS NOT DISTINCT FROM b`, `(a = b) OR (a IS NULL AND b is NULL)`; all of which did not work (they all result in `ERROR: FULL JOIN is only supported with merge-joinable or hash-joinable join conditions`) I'm less certain that it is possible. Alternatively, we may need to change the NULL semantics to align it with SQL - this seems like likely the simpler solution, allowing us to generate simple, reliable SQL - the NULL=NULL solution will be cornering us into nasty workarounds very dependent on the particular backend.
PR adds a flag to `Text` implementation tracking whether it is in a FCD normal form. Then this information can be used in the `Normalizer.compare` method.

`Any.==` is a builtin method. The semantics is the same as it used to be, except that we no longer assume `x == y` iff `Meta.is_same_object x y`, which used to be the case and caused failures in table tests.
# Important Notes
Measurements from `EqualsBenchmarks` shows that the performance of `Any.==` for recursive atoms increased by roughly 20%, and the performance for primitive types stays roughly the same.
First part of fixing `Text.to_text`.
- add: `pretty` method for pretty printing.
- update: make `Text.to_text` conversion identity for Text
In the next iterations `to_text` will be gradually replaced with `to Text` conversion once the related issues with conversions are fixed.
Implements `getMetaObject` and related messages from Truffle interop for Enso values and types. Turns `Meta.is_a` into builtin and re-uses the same functionality.
# Important Notes
Adds `ValueGenerator` testing infrastructure to provide unified access to special Enso values and builtin types that can be reused by other tests, not just `MetaIsATest` and `MetaObjectTest`.
Use JavaScript to parse and serialise to JSON. Parses to native Enso object.
- `.to_json` now returns a `Text` of the JSON.
- Json methods now `parse`, `stringify` and `from_pairs`.
- New `JSON_Object` representing a JavaScript Object.
- `.to_js_object` allows for types to custom serialize. Returning a `JS_Object`.
- Default JSON format for Atom now has a `type` and `constructor` property (or method to call for as needed to deserialise).
- Removed `.into` support for now.
- Added JSON File Format and SPI to allow `Data.read` to work.
- Added `Data.fetch` API for easy Web download.
- Default visualization for JS Object trunctes, and made Vector default truncate children too.
Fixes defect where types with no constructor crashed on `to_json` (e.g. `Matching_Mode.Last.to_json`.
Adjusted default visualisation for Vector, so it doesn't serialise an array of arrays forever.
Likewise, JS_Object default visualisation is truncated to a small subset.
New convention:
- `.get` returns `Nothing` if a key or index is not present. Takes an `other` argument allowing control of default.
- `.at` error if key or index is not present.
- `Nothing` gains a `get` method allowing for easy propagation.
This removes the special handling of polyglot exceptions and allows matching on Java exceptions in the same way as for any other types.
`Polyglot_Error`, `Panic.catch_java` and `Panic.catch_primitive` are gone
The change mostly deals with the backslash of removing `Polyglot_Error` and two `Panic` methods.
`Panic.catch` was implemented as a builtin instead of delegating to `Panic.catch_primitive` builtin that is now gone.

Benchmark to compare _curried and lambda_ based function invocations and a fix to make _curried_ invocation (at least) as fast as the _lambda_ one. Allows us to use _curried invocations_ in standard library again without loosing any speed.
# Important Notes
Execute as:
```
sbt:runtime> benchOnly CurriedFunctionBenchmarks
```
Prior to subsequent bugfixes in this PR the benchmark results were:
- `averageCurried` runs in 0.290 ms
- `averageLambda` runs in 0.122 ms
e.g. _curried invocations_ is more than twice slow. That confirms our findings from the `Array_Proxy` vector benchmarks. The problem is that _function object is not compilation final_. After fixing it we have following results:
- `averageCurried` runs in 0.102 ms
- `averageLambda` runs in 0.111 ms
e.g. both operations are of similar complexity.
- Implemented https://www.pivotaltracker.com/story/show/183913276
- Refactored MultiValueIndex and MultiValueKeys to be more type-safe and more direct about using ordered or unordered maps.
- Added performance tests ensuring we use an efficient algorithm for the joins (the tests will fail for a full O(N*M) scan).
- Removed some duplicate code in the Table library.
- Added optional coloring of test results in terminal to make failures easier to spot.
- Aligned `compare_to` so returns `Type_Error` if `that` is wrong type for `Text`, `Ordering` and `Duration`.
- Add `empty_object`, `empty_array`. `get_or_else`, `at`, `field_names` and `length` to `Json`.
- Fix `Json` serialisation of NaN and Infinity (to "null").
- Added `length`, `at` and `to_vector` to Pair (allowing it to be treated as a Vector).
- Added `running_fold` to the `Vector` and `Range`.
- Added `first` and `last` to the `Vector.Builder`.
- Allow `order_by` to take a single `Sort_Column` or have a mix of `Text` and `Sort_Column.Name` in a `Vector`.
- Allow `select_columns_helper` to take a `Text` value. Allows for a single field in group_by in cross_tab.
- Added `Patch` and `Custom` to HTTP_Method.
- Added running `Statistic` calculation and moved more of the logic from Java to Enso. Performance seems similar to pure Java version now.
Add `Test.with_clue` function similar to ScalaTest's [with_clue](https://www.scalatest.org/user_guide/using_assertions).
This is useful for tests where the assertion depends on context which is not clear from it's operands.
### Important Notes
Using with_clue changes `State Clue` which is extracted by the `fail` function.
The State is introduced by `Test.specify` when the test is not pending.
There should be no changes to the public API apart form the addition of `Test.with_clue`.
Using lambda instead of higher order function.
# Important Notes
Running:
```
sbt:runtime> benchOnly VectorBenchmarks.averageOverArrayProxy
```
speeds up from `0.038 ms/op` to `0.016 ms/op` on my computer. Which seems good enough.
* Sequence literal (Vector) should preserve warnings
When Vector was created via a sequence literal, we simply dropped any
associated any warnings associated with it.
This change propagates Warnings during the creation of the Vector.
Ideally, it would be sufficient to propagate warnings from the
individual elements to the underlying storage but doesn't go well with
`Vector.fromArray`.
* update changelog
* Array-like structures preserver warnings
Added a WarningsLibrary that exposes `hasWarnings` and `getWarnings`
messages. That way we can have a single storage that defines how to
extract warnings from an Array and the others just delegate to it.
This simplifies logic added to sequence literals to handle warnings.
* Ensure polyglot method calls are warning-free
Since warnings are no longer automatically extracted from Array-like
structures, we delay the operation until an actual polyglot method call
is performed.
Discovered a bug in `Warning.detach_selected_warnings` which was missing
any usage or tests.
* nits
* Support multi-dimensional Vectors with warnings
* Propagate warnings from case branches
* nit
* Propagate all vector warnings when reading element
Previously, accessing an element of an Array-like structure would only
return warnings of that element or of the structure itself.
Now, accessing an element also returns warnings from all its elements as
well.

# Important Notes
- Moved `to_json` and `to_default_visualization_data` from base types to extension methods.
Converting `Integer.parse` into a builtin and making sure it can parse big values like `100!`. Adding `locale` parameter to `Locale.parse` and making sure it parses `32,5` as `32.5` double in Czech locale.
# Important Notes
Note that one cannot
```
import Standard.Table as Table_Module
```
because of the 2-component name restriction that gets desugared to `Standard.Table.Main` and we have to write
```
import Standard.Table.Main as Table_Module
```
in a few places. Once we move `Json.to_table` extension this can be improved.
It appears that when were doing
`from XYZ import all`
the module `XYZ` was also being taken into account during name resolution.
This was unfortunate and became problematic when one had a type with the same name defined in it.
During pattern matching one could not simply do
```
from XYZ import all
...
case ... of
_ : XYZ -> ...
```
since the compiler would complain that we try to pattern match on a type but give it a module.
The module is now excluded from the name resolution, when importing everything from the module.
It appears that this "feature" was used in a number of our tests, so they had to be adapted.
This fixes task 4 in https://www.pivotaltracker.com/story/show/183833055
- Adds transpose and cross_tab to the In-Memory table.
- Cross Tab is built on top of aggregate and hence allows for expressions and has same error trapping as in aggregate.
# Important Notes
Only basic tests have been implemented. Error and warning tests will be added as a follow up task.
Implements https://www.pivotaltracker.com/story/show/183854123
It features a naive full scan join and only allows equality conditions. More advanced conditions and better optimized algorithms will be implemented in a subsequent PR.
- Export all for `Problem_Behavior` (allowing for Report_Warning, Report_Error and Ignore to be trivially used).
- Renamed `Range.Range_Data` to `Range.Value` moved to using `up_to` wherever possible.
- Reviewed `Function`, `IO`, `Polyglot`, `Random`, `Runtime`, `System`.
- `File` now published as type. Some static methods moved to `Data` others into type. Removed `read_bytes` static.

- Added `Random` module to the exports.
- Move static methods into `Warning` type and exporting the type not the module.
# Important Notes
- Sorted a few imports into order (ordering by direct import in project, then by from import in project then polyglot and finally self imports).
RuntimeStdlibTest now checks that names in type signatures are qualified (aka poor man's typechecker)
Will be merged after the stdlib tidying by James is complete.
Here we go again...

- Add `column_names` method to `Table` as a shorthand.
- Return data flow error when comparing with Nothing (not a Panic or a Polyglot exception).

# Important Notes
- Added a load of tests for the various comparison operators to Numbers_Spec.
It appears that we were always adding builtin methods to the scope of the module and the builtin type that shared the same name.
This resulted in some methods being accidentally available even though they shouldn't.
This change treats differently builtins of types and modules and introduces auto-registration feature for builtins.
By default all builtin methods are registered with a type, unless explicitly defined in the annotation property.
Builtin methods that are auto-registered do not have to be explicitly defined and are registered with the underlying type.
Registration correctly infers the right type, depending whether we deal with static or instance methods.
Builtin methods that are not auto-registered have to be explicitly defined **always**. Modules' builtin methods are the prime example.
# Important Notes
Builtins now carry information whether they are static or not (inferred from the lack of `self` parameter).
They also carry a `autoRegister` property to determine if a builtin method should be automatically registered with the type.
Libraries: Revert changes that were necessitated by a new rule we have decided not to introduce.
Parser:
- Support mixed constructors/bindings in types.
- Disallow zero-length hex sequences in character escapes: `\x`, `\u`, `\u{}`, `\U`, `\U{}` are no longer legal synonyms for `\0` (matches old parser behavior).
Computing length of a text takes time. Let's cache it after first computation.
# Important Notes
Wrote `StringBenchmarks` that sums lengths of (the same) `Text` present many time in a `Vector`. Initially it took `383.673 ms` per operation. Then it took `0.031 ms/op`. Looks like the `length` calls are returning instantly as they get cached.
- Added expression ANTLR4 grammar and sbt based build.
- Added expression support to `set` and `filter` on the Database and InMemory `Table`.
- Added expression support to `aggregate` on the Database and InMemory `Table`.
- Removed old aggregate functions (`sum`, `max`, `min` and `mean`) from `Column` types.
- Adjusted database `Column` `+` operator to do concatenation (`||`) when text types.
- Added power operator `^` to both `Column` types.
- Adjust `iif` to allow for columns to be passed for `when_true` and `when_false` parameters.
- Added `is_present` to database `Column` type.
- Added `coalesce`, `min` and `max` functions to both `Column` types performing row based operation.
- Added support for `Date`, `Time_Of_Day` and `Date_Time` constants in database.
- Added `read` method to InMemory `Column` returning `self` (or a slice).
# Important Notes
- Moved approximate type computation to `SQL_Type`.
- Fixed issue in `LongNumericOp` where it was always casting to a double.
- Removed `head` from InMemory Table (still has `first` method).
Fix bugs in `TreeToIr` (rewrite) and parser. Implement more undocumented features in parser. Emulate some old parser bugs and quirks for compatibility.
Changes in libs:
- Fix some bugs.
- Clean up some odd syntaxes that the old parser translates idiosyncratically.
- Constructors are now required to precede methods.
# Important Notes
Out of 221 files:
- 215 match the old parser
- 6 contain complex types the old parser is known not to handle correctly
So, compared to the old parser, the new parser parses 103% of files correctly.
This PR adds `Period` type, which is a date-only complement to `Duration` builtin type.
# Important Notes
- `Period` replaces `Date_Period`, and `Time_Period`.
- Added shorthand constructors for `Duration` and `Period`. For example: `Period.days 10` instead of `Period.new days=10`.
- `Period` can be compared to other `Period` in some cases, other cases throw an error.
Define start of Enso epoch as 15th of October 1582 - start of the Gregorian calendar.
# Important Notes
- Some (Gregorian) calendar related functionalities within `Date` and `Date_Time` now produces a warning if the receiving Date/Date_Time is before the epoch start, e.g., `week_of_year`, `is_leap_year`, etc.
1. Changes how we do monadic state – rather than a haskelly solution, we now have an implicit env with mutable data inside. It's better for the JVM. It also opens the possibility to have state ratained on exceptions (previously not possible) – both can now be implemented.
2. Introduces permission check system for IO actions.
Another part of #3611 with few more `TreeToIr` improvements.
# Important Notes
Unofficial `LoadParser.sh` check from #3611 of all library files now reports just 54 failures out of 222 files - e.g. 75% success rate.
The main culprit of a Vector slowdown (when compared to Array) was the normalization of the index when accessing the elements. Turns out that the Graal was very persistent on **not** inlining that particular fragment and that was degrading the results in benchmarks.
Being unable to force it to do it (looks like a combination of thunk execution and another layer of indirection) we resorted to just moving the normalization to the builtin method. That makes Array and Vector perform roughly the same.
Moved all handling of invalid index into the builtin as well, simplifying the Enso implementation. This also meant that `Vector.unsafe_at` is now obsolete.
Additionally, added support for negative indices in Array, to behave in the same way as for Vector.
# Important Notes
Note that this workaround only addresses this particular perf issue. I'm pretty sure we will have more of such scenarios.
Before the change `averageOverVector` benchmark averaged around `0.033 ms/op` now it does consistently `0.016 ms/op`, similarly to `averageOverArray`.
Improve `Unsupported_Argument_Types` error so that it includes the message from the original exception. `arguments` field is retained, but not included in `to_display_text` method.
- Removed `Dubious constructor export` from Examples, Geo, Google_Api, Image and Test.
- Updated Google_Api project to meet newer code standards.
- Restructured `Standard.Test`:
- `Main.enso` now exports `Bench`, `Faker`, `Problems`, `Test`, `Test_Suite`
- `Test.Suite` methods moved into a `Test_Suite` type.
- Moved `Bench.measure` into `Bench` type.
- Separated the reporting to a `Test_Reporter` module.
- Moved `Faker` methods into `Faker` type.
- Removed `Verbs` and `.should` method.
- Added `should_start_with` and `should_contain` extensions to `Any`.
- Restructured `Standard.Image`:
- Merged Codecs methods into `Image`.
- Export `Image`, `Read_Flag`, `Write_Flag` and `Matrix` as types from `Main.enso`.
- Merged the internal methods into `Matrix` and `Image`.
- Fixed `Day_Of_Week` to be exported as a type and sort the `from` method.
- Reimplement the `Duration` type to a built-in type.
- `Duration` is an interop type.
- Allow Enso method dispatch on `Duration` interop coming from different languages.
# Important Notes
- The older `Duration` type should now be split into new `Duration` builtin type and a `Period` type.
- This PR does not implement `Period` type, so all the `Period`-related functionality is currently not working, e.g., `Date - Period`.
- This PR removes `Integer.milliseconds`, `Integer.seconds`, ..., `Integer.years` extension methods.
- Moved `Standard.Database.connect` into `Standard.Database.Database.connect`, so can now just `from Standard.Database import ...`.
- Removed all `Dubious constructor export`s.
- Switched to using `project` for internal imports.
- Moved to using `Value` for private constructors and not re-exporting.
- Export types not modules from `Standard.Database`.
- Broke up `IR` into separate files (Context, Expression, From_Spec, Internal_Column, Join_Kind, Query).
- No longer use `IR.` instead via specific types.
- Broke up `SQL` into separate files (SQL_Type and SQL_Statement).
Additionally;
- Standard.Table: Moved `storage_types` into `Storage`.
- Standard.Table: Switched to using `project` for internal imports.
- Standard.Table.Excel: Renamed modules `Range` to `Excel_Range` and `Section` to `Excel_Section`.
- `Standard.Visualisation`: Switched to using `project` for internal imports.
- `Standard.Visualisation`: Moved to using `Value` for private constructors and not re-exporting.
# Important Notes
- Have not cleared up the `Errors` yet.
- Have not switched to type pattern matching.
- Generally export types not modules from the `Standard.Table` import.
- Moved `new`, `from_rows` the `Standard.Table` library into the `Table` type.
- Renames `Standard.Table.Data.Storage.Type` to `Standard.Table.Data.Storage.Storage`
- Removed the internal `from_columns` method.
- Removed `join` and `concat` and merged into instance methods.
- Removed `Table` and `Column` from the `Standard.Database` exports.
- Removed `Standard.Table.Data.Column.Aggregate_Column` as not used any more.
- Adds a `details` field to `Failure` for additional contextual information.
- Stacktraces are moved from main message (which should generally be short and fit in one line) to the `details`.
- Ensuring that the attribute does not contain multiple lines fixes the CI viewer which seems to have been breaking on multiline attributes.
- Additionally, test execution time is now measured and printed in the CLI as well as included in the JUnit report for the CI - we can use this to catch tests running unexpectedly slowly.
Changelog
- fix reporting of runtime type for values annotated with warning
- fix visualizations of values annotated with warnings
- fix `Runtime.get_stack_trace` failure in interactive mode
Allows using `Vector ColumnName` for the various table functions as short hand.
- `select_columns`, `remove_columns`,`reorder_columns`, `distinct` all map to an exact By_Name match.
- `rename_columns` does a positional rename on the Vector passed.
- `order_by` sorts ascending on each column passed in order.
# Important Notes
This may be reversed once widgets are available and working but this makes the APIs much more usable in current UI.
This change brings by-type pattern matching to Enso.
One can pattern match on Enso types as well as on polyglot types.
For example,
```
case x of
_ : Integer -> ...
_ : Text -> ...
_ -> ...
```
as well as Java's types
```
case y of
_ : ArrayList -> ...
_ : List -> ...
_ : AbstractList -> ...
_ -> ..
```
It is no longer possible to match a value with a corresponding type constructor.
For example
```
case Date.now of
Date -> ...
```
will no longer match and one should match on the type (`_ : Date`) instead.
```
case Date of
Date -> ...
```
is fine though, as requested in the ticket.
The change required further changes to `type_of` logic which wasn't dealing well with polyglot values.
Implements https://www.pivotaltracker.com/story/show/183188846
# Important Notes
~I discovered late in the game that nested patterns involving type patterns, such as `Const (f : Foo) tail -> ...` are not possible due to the old parser logic.
I would prefer to add it in a separate PR because this one is already getting quite large.~ This is now supported!
Implements https://www.pivotaltracker.com/story/show/183402892
# Important Notes
- Fixes inconsistent `compare_to` vs `==` behaviour in date/time types and adds test for that.
- Adds test for `Table.order_by` on dates and custom types.
- Fixes an issue with `Table.order_by` for custom types.
- Unifies how incomparable objects are reported by `Table.order_by` and `Vector.sort`.
- Adds benchmarks comparing `Table.order_by` and `Vector.sort` performance.
Makes statics static. A type and its instances have different methods defined on them, as it should be. Constructors are now scoped in types, and can be imported/exported.
# Important Notes
The method of fixing stdlib chosen here is to just not. All the conses are exported to make all old code work. All such instances are marked with `TODO Dubious constructor export` so that it can be found and fixed.
This change implements a simple `type_of` method that returns a type of a given value, including for polyglot objects.
The change also allows for pattern matching on various time-related instances. It is a nice-to-have on its own, but it was primarily needed here to write some tests. For equality checks on types we currently can't use `==` due to a known _feature_ which essentially does wrong dispatching. This will be improved in the upcoming statics PR so we agreed that there is no point in duplicating that work and we can replace it later.
Also, note that this PR changes `Meta.is_same_object`. Comparing types revealed that it was wrong when comparing polyglot wrappers over the same value.
Use an `ArraySlice` to slice `Vector`.
Avoids memory copying for the slice function.

# Important Notes
- Removed unnecessary invocations of `Error.throw` improving performance of `Vector.distinct`. The time of the `add_work_days and work_days_until should be consistent with each other` test suite came down from 15s to 3s after the changes.
Repairing the constructor name following the types work. Some general tiding up as well.
- Remove `Standard.Database.Data.Column.Aggregate_Column_Builder`.
- Remove `Standard.Database.Data.Dialect.Dialect.Dialect_Data`.
- Remove unused imports and update some type definitions.
- Rename `Postgres.Postgres_Data` => `Postgres_Options.Postgres`.
- Rename `Redshift.Redshift_Data` => `Redshift_Options.Redshift`.
- Rename `SQLite.SQLite_Data` => `SQLite_Options.SQLite`.
- Rename `Credentials.Credentials_Data` => `Credentials.Username_And_Password`.
- Rename `Sql` to `SQL` across the board.
- Merge `Standard.Database.Data.Internal` into `Standard.Database.Internal`.
- Move dialects into `Internal` and merge the function in `Helpers` into `Base_Generator`.
Turns that if you import a two-part import we had special code that would a) add Main submodule b) add an explicit rename.
b) is problematic because sometimes we only want to import specific names.
E.g.,
```
from Bar.Foo import Bar, Baz
```
would be translated to
```
from Bar.Foo.Main as Foo import Bar, Baz
```
and it should only be translated to
```
from Bar.Foo.Main import Bar, Baz
```
This change detects this scenario and does not add renames in that case.
Fixes [183276486](https://www.pivotaltracker.com/story/show/183276486).
Changes following Marcin's work. Should be back to very similar public API as before.
- Add an "interface" type: `Standard.Base.System.File_Format.File_Format`.
- All `File_Format` types now have a `can_read` method to decide if they can read a file.
- Move `Standard.Table.IO.File_Format.Text.Text_Data` to `Standard.Base.System.File_Format.Plain_Text_Format.Plain_Text`.
- Move `Standard.Table.IO.File_Format.Bytes` to `Standard.Base.System.File_Format.Bytes`.
- Move `Standard.Table.IO.File_Format.Infer` to `Standard.Base.System.File_Format.Infer`. **(doesn't belong here...)**
- Move `Standard.Table.IO.File_Format.Unsupported_File_Type` to `Standard.Base.Error.Common.Unsupported_File_Type`.
- Add `Infer`, `File_Format`, `Bytes`, `Plain_Text`, `Plain_Text_Format` to `Standard.Base` exports.
- Fold extension methods of `Standard.Base.Meta.Unresolved_Symbol` into type.
- Move `Standard.Table.IO.File_Format.Auto` to `Standard.Table.IO.Auto_Detect.Auto_Detect`.
- Added a `types` Vector of all the built in formats.
- `Auto_Detect` asks each type if they `can_read` a file.
- Broke up and moved `Standard.Table.IO.Excel` into `Standard.Table.Excel`:
- Moved `Standard.Table.IO.File_Format.Excel.Excel_Data` to `Standard.Table.Excel.Excel_Format.Excel_Format.Excel`.
- Renamed `Sheet` to `Worksheet`.
- Internal types `Reader` and `Writer` providing the actual read and write methods.
- Created `Standard.Table.Delimited` with similar structure to `Standard.Table.Excel`:
- Moved `Standard.Table.IO.File_Format.Delimited.Delimited_Data` to `Standard.Table.Delimited.Delimited_Format.Delimited_Format.Delimited`.
- Moved `Standard.Table.IO.Quote_Style` to `Standard.Table.Delimited.Quote_Style`.
- Moved the `Reader` and `Writer` internal types into here. Renamed methods to have unique names.
- Add `Aggregate_Column`, `Auto_Detect`, `Delimited`, `Delimited_Format`, `Excel`, `Excel_Format`, `Sheet_Names`, `Range_Names`, `Worksheet` and `Cell_Range` to `Standard.Table` exports.
`Vector` type is now a builtin type. This requires a bunch of additional builtin methods for its creation:
- Use `Vector.from_array` to convert any array-like structure into a `Vector` [by copy](f628b28f5f)
- Use (already existing) `Vector.from_polyglot_array` to convert any array-like structure into a `Vector` **without** copying
- Use (already existing) `Vector.fill 1 item` to create a singleton `Vector`
Additional, for pattern matching purposes, we had to implement a `VectorBranchNode`. Use following to match on `x` being an instance of `Vector` type:
```
import Standard.Base.Data.Vector
size = case x of
Vector.Vector -> x.length
_ -> 0
```
Finally, `VectorLiterals` pass that transforms `[1,2,3]` to (roughly)
```
a1 = 1
a2 = 2
a3 = 3
Vector (Array (a1,a2, a3))
```
had to be modified to generate
```
a1 = 1
a2 = 2
a3 = 3
Vector.from_array (Array (a1, a2, a3))
```
instead to accomodate to the API changes. As of 025acaa676 all the known CI checks passes. Let's start the review.
# Important Notes
Matching in `case` statement is currently done via `Vector_Data`. Use:
```
case x of
Vector.Vector_Data -> True
```
until a better alternative is found.
Small clean up PR.
- Aligns a few type signatures with their functions.
- Some formatting fixes.
- Remove a few unused types.
- Make error extension functions be standard methods.
- Added `databases`, `database`, `set_database`.
- Added `schemas`, `schema`, `set_schema`.
- Added `table_types`,
- Added `tables`.
- Moved the vast majority of the connection work into a lower level `JDBC_Connection` object.
- `Connection` represents the standard API for database connections and provides a base JDBC implementation.
- `SQLite_Connection` has the `Connection` API but with custom `databases` and `schemas` methods for SQLite.
- `Postgres_Connection` has the `Connection` API but with custom `set_database`, `databases`, `set_schema` and `schemas` methods for Postgres.
- Updated `Redshift` - no public API change.

# Important Notes
- Modified standard library Java helpers dependencies so that `std-table` module depends on `std-base`, as a provided dependency. This is allowed, because `std-table` is used by the `Standard.Table` Enso module which depends on `Standard.Base` which ensures that the `std-base` is loaded onto the classpath, thus whenever `std-table` is loaded by `Standard.Table`, so is `std-base`. Thus we can rely on classes from `std-base` and its dependencies being _provided_ on the classpath. Thanks to that we can use utilities like `Text_Utils` also in `std-table`, avoiding code duplication. Additional advantage of that is that we don't need to specify ICU4J as a separate dependency for `std-table`, since it is 'taken' from `std-base` already - so we avoid including it in our build packages twice.
This is a step towards the new language spec. The `type` keyword now means something. So we now have
```
type Maybe a
Some (from_some : a)
None
```
as a thing one may write. Also `Some` and `None` are not standalone types now – only `Maybe` is.
This halfway to static methods – we still allow for things like `Number + Number` for backwards compatibility. It will disappear in the next PR.
The concept of a type is now used for method dispatch – with great impact on interpreter code density.
Some APIs in the STDLIB may require re-thinking. I take this is going to be up to the libraries team – some choices are not as good with a semantically different language. I've strived to update stdlib with minimal changes – to make sure it still works as it did.
It is worth mentioning the conflicting constructor name convention I've used: if `Foo` only has one constructor, previously named `Foo`, we now have:
```
type Foo
Foo_Data f1 f2 f3
```
This is now necessary, because we still don't have proper statics. When they arrive, this can be changed (quite easily, with SED) to use them, and figure out the actual convention then.
I have also reworked large parts of the builtins system, because it did not work at all with the new concepts.
It also exposes the type variants in SuggestionBuilder, that was the original tiny PR this was based on.
PS I'm so sorry for the size of this. No idea how this could have been smaller. It's a breaking language change after all.
- Added `Zone`, `Date_Time` and `Time_Of_Day` to `Standard.Base`.
- Renamed `Zone` to `Time_Zone`.
- Added `century`.
- Added `is_leap_year`.
- Added `length_of_year`.
- Added `length_of_month`.
- Added `quarter`.
- Added `day_of_year`.
- Added `Day_Of_Week` type and `day_of_week` function.
- Updated `week_of_year` to support ISO.
# Important Notes
- Had to pass locale to formatter for date/time tests to work on my PC.
- Changed default of `week_of_year` to use ISO.
Implements https://www.pivotaltracker.com/story/show/182879865
# Important Notes
Note that removing `set_at` still does not make our arrays fully immutable - `Array.copy` can still be used to mutate them.
* Builtin Date_Time, Time_Of_Day, Zone
Improved polyglot support for Date_Time (formerly Time), Time_Of_Day and
Zone. This follows the pattern introduced for Enso Date.
Minor caveat - in tests for Date, had to bend a lot for JS Date to pass.
This is because JS Date is not really only a Date, but also a Time and
Timezone, previously we just didn't consider the latter.
Also, JS Date does not deal well with setting timezones so the trick I
used is to first call foreign function returning a polyglot JS Date,
which is converted to ZonedDateTime and only then set the correct
timezone. That way none of the existing tests had to be changes or
special cased.
Additionally, JS deals with milliseconds rather than nanoseconds so
there is loss in precision, as noted in Time_Spec.
* Add tests for Java's LocalTime
* changelog
* Make date formatters in table happy
* PR review, add more tests for zone
* More tests and fixed a bug in column reader
Column reader didn't take into account timezone but that was a mistake
since then it wouldn't map to Enso's Date_Time.
Added tests that check it now.
* remove redundant conversion
* Update distribution/lib/Standard/Base/0.0.0-dev/src/Data/Time.enso

Use Proxy_Polyglot_Array as a proxy for polyglot arrays, thus unifying
the way the underlying array is accessed in Vector.
Used the opportunity to cleanup builtin lookup, which now actually
respects what is defined in the body of @Builtin_Method annotation.
Also discovered that polyglot null values (in JS, Python and R) were leaking to Enso.
Fixed that by doing explicit translation to `Nothing`.

First of all this PR demonstrates how to implement _lazy visualization_:
- one needs to write/enhance Enso visualization libraries - this PR adds two optional parameters (`bounds` and `limit`) to `process_to_json_text` function.
- the `process_to_json_text` can be tested by standard Enso test harness which this PR also does
- then one has to modify JavaScript on the IDE side to construct `setPreprocessor` expression using the optional parameters
The idea of _scatter plot lazy visualization_ is to limit the amount of points the IDE requests. Initially the limit is set to `limit=1024`. The `Scatter_Plot.enso` then processes the data and selects/generates the `limit` subset. Right now it includes `min`, `max` in both `x`, `y` axis plus randomly chosen points up to the `limit`.
The D3 visualization widget is capable of _zooming in_. When that happens the JavaScript widget composes new expression with `bounds` set to the newly visible area. By calling `setPreprocessor` the engine recomputes the visualization data, filters out any data outside of the `bounds` and selects another `limit` points from the new data. The IDE visualization then updates itself to display these more detailed data. Users can zoom-in to see the smallest detail where the number of points gets bellow `limit` or they can select _Fit all_ to see all the data without any `bounds`.
# Important Notes
Randomly selecting `limit` samples from the dataset may be misleading. Probably implementing _k-means clustering_ (where `k=limit`) would generate more representative approximation.
- Removed various unnecessary `Standard.Base` imports still left behind.
- Added `Regex` to default `Standard.Base`.
- Removed aliasing from the examples as no longer needed (case coercion no long occurs).
- Remove `import Standard.Table` from within the Table library (directly importing types).
- Reviewed what was in `Standard.Database` - a few tweaks and removals.
- Removed various un-needed aliasing following Hubert's import work.
