- Removed Array methods: `new`, `copy` and `new_[1234]`.
- New builtins for `Vector.insert`, `Vector.remove` and `Vector.flatten`.
- Replaced `Vector_Builder` use of `Array.copy` to a `Vector.Builder` approach.
Mostly stuff to tidy up the static methods in the CB.
- Remove default pattern from `parse_to_table` (caused IDE to freeze).
- Rename any `_` arguments to what they are.
- Merge `Date.now` into `Date.today`
- Merge the Interval constructors into a single constructor.
- Hide various methods.
Fixes#6955 by:
- using `visualisationModule` to specify the module where the visualization is to be used
- referring to method in `Meta.get_annotation` with `.method_name` - e.g. unresolved symbol notation
- evaluating arguments to `Meta.get_annotation` in the context of the user module (which can access the extension functions)
- Removed `module` argument from `enso_project` (new `Project_Description.new` API).
- Removed the custom option from date and time parse/format dropdowns.
- The `format` dropdown uses the value to create the dropdown. (Screenshot below)
- Removed `StorageType` coalescing rules and replaced them with simpler logic in `ObjectStorage`.
- Update signature for `add_row_number` and add aliases.
- Add type detection for `Mixed` columns when calling column functions.
- Excel uses column name for missing headers.
- Add aliases for parse functions on text.
- Adjust `Date`, `Time_Of_Day` and `Date_Time` parse functions to not take `Nothing` anymore and provide dropdowns.
- Removed built-in parses.
- All support Locale.
- Add support for missing day or year for parsing a Date.
- All will trim values automatically.
- Added ability to list AWS profiles.
- Added ability to list S3 buckets.
- Workaround for Table.aggregate so default item added works.
This adds the spec for all update actions, but implements the common input validation framework and `Insert`. Tests for remaining actions are marked as pending - these will be implemented in a subsequent PR.
Related to #6912
It essentially solves it by removing any builtins that would take an EnsoDate/EnsoTimeOfDay/EnsoTimeZone and replacing them with Java utils that do the same operation.
This is not a proper solution - the builtin conversion is still invalid for the date/time types - but at this moment we may just no longer use the invalid conversion so it is much less of an issue. We still need to be aware of this if we want to introduce builtins taking date/time in the future.
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`.

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`.

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

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)

- 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.
- Handle `WithWarnings` in `IndirectInvokeCallableNode`.
- Handle no RootNode in `ErrorResolver`.
- Allow table vizualisation to cope if no `data` passed.
- Add `Warning.has_warnings` to check if warnings present.
- Adjust `set_value` for `JS_Object` so creates a new object each time.
- 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:

# 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).
