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.

# 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.
