More and more often I need a way to only recover a specific type of a dataflow error (in a similar manner as with panics). So the API for `Error.catch` has been amended to more closely resemble `Panic.catch`, allowing to handle only specific types of dataflow errors, passing others through unchanged. The default is `Any`, meaning all errors are caught by default, and the behaviour of `x.catch` remains unchanged.
implement simple variable assignments and function definitions.

- https://www.pivotaltracker.com/story/show/182497144 (the code blocks are not created yet, but the function declaration is recognized.)
# Important Notes
- Introduced S-expression-based tests, and pretty-printing-roundtrip testing.
- Started writing tests for TypeDef based on the examples in the issue. None of them parse successfully.
- Fixed Number tokenizing.
- Moved most contents of parser's `main.rs` to `lib.rs` (fixes a warning).
Hooking up Reporting_Stream_Encoder_Spec reveals missing renaming.
Also removed one more `here.` that wasn't run in tests.
Kudos to @radeusgd for finding those!
Modified UppercaseNames to now resolve methods without an explicit `here` to point to the current module.
`here` was also often used instead of `self` which was allowed by the compiler.
Therefore UppercaseNames pass is now GlobalNames and does some extra work -
it translated method calls without an explicit target into proper applications.
# Important Notes
There was a long-standing bug in scopes usage when compiling standalone expressions.
This resulted in AliasAnalysis generating incorrect graphs and manifested itself only in unit tests
and when running `eval`, thus being a bit hard to locate.
See `runExpression` for details.
Additionally, method name resolution is now case-sensitive.
Obsolete passes like UndefinedVariables and ModuleThisToHere were removed. All tests have been adapted.
Adds support for appending to an existing Excel table.
# Important Notes
- Renamed `Column_Mapping` to `Column_Name_Mapping`
- Changed new type name to `Map_Column`
- Added last modified time and creation time to `File`.
Implement generation of Java AST types from the Rust AST type definitions, with support for deserializing in Java syntax trees created in Rust.
### New Libraries
#### `enso-reflect`
Implements a `#[derive(Reflect)]` macro to enable runtime analysis of datatypes. Macro interface includes helper attributes; **the Rust types and the `reflect` attributes applied to them fully determine the Java types** ultimately produced (by `enso-metamodel`). This is the most important API, as it is used in the subject crates (`enso-parser`, and dependencies with types used in the AST). [Module docs](https://github.com/enso-org/enso/blob/wip/kw/parser/ast-transpiler/lib/rust/reflect/macros/src/lib.rs).
#### `enso-metamodel`
Provides data models for data models in Rust/Java/Meta (a highly-abstracted language-independent model--I have referred to it before as the "generic representation", but that was an overloaded term).
The high-level interface consists of operations on data models, and between them. For example, the only operations needed by [the binary that drives datatype transpilation](https://github.com/enso-org/enso/blob/wip/kw/parser/ast-transpiler/lib/rust/parser/generate-java/src/main.rs) are: `rust::to_meta`, `java::from_meta`, `java::transform::optional_to_null`, `java::to_syntax`.
The low-level interface consists of direct usage of the datatypes; this is used by [the module that implements some serialization overrides](https://github.com/enso-org/enso/blob/wip/kw/parser/ast-transpiler/lib/rust/parser/generate-java/src/serialization.rs) (so that the Java interface to `Code` references can produce `String`s on demand based on serialized offset/length pairs). The serialization override mechanism is based on customizing, not replacing, the generated deserialization methods, so as to be as robust as possible to changes in the Rust source or in the transpilation process.
### Important Notes
- Rust/Java serialization is exhaustively tested for structural compatibility. A function [`metamodel::meta::serialization::testcases`](https://github.com/enso-org/enso/blob/wip/kw/parser/ast-transpiler/lib/rust/metamodel/src/meta/serialization.rs) uses `reflect`-derived data to generate serialized representations of ASTs to use as test cases. Its should-accept cases cover every type a tree can contain; it also produces a representative set of should-reject cases. A Rust `#[test]` confirms that these cases are accepted/rejected as expected, and generated Java tests (see Binaries below) check the generated Java deserialization code against the same test cases.
- Deserializing `Code` is untested. The mechanism is in place (in Rust, we serialize only the offset/length of the `Cow`; in Java, during deserialization we obtain a context object holding a buffer for all string data; the accessor generated in Java uses the buffer and the offset/length to return `String`s), but it will be easier to test once we have implemented actually parsing something and instantiating the `Cow`s with source code.
- `#[tagged_enum]` [now supports](https://github.com/enso-org/enso/blob/wip/kw/parser/ast-transpiler/lib/rust/shapely/macros/src/tagged_enum.rs#L36-L51) control over what is done with container-level attributes; they can be applied to the container and variants (default), only to the container, or only to variants.
- Generation of `sealed` classes is supported, but currently disabled by `TARGET_VERSION` in `metamodel::java::syntax` so that tests don't require Java 15 to run. (The same logic is run either way; there is a shallow difference in output.)
### Binaries
The `enso-parser-generate-java` crate defines several binaries:
- `enso-parser-generate-java`: Performs the transpilation; after integration, this will be invoked by the build script.
- `java-tests`: Generates the Java code that tests format deserialization; after integration this command will be invoked by the build script, and its Java output compiled and run during testing.
- `graph-rust`/`graph-meta`/`graph-java`: Produce GraphViz representations of data models in different typesystems; these are for developing and understanding model transformations.
Until integration, a **script regenerates the Java and runs the format tests: `./tools/parser_generate_java.sh`**. The generated code can be browsed in `target/generated_java`.
If a node created by the user gets placed off-screen, the screen's camera is panned to make the node visible.

#### Visuals
A screencast showing a number of node creation scenarios when the camera is panned to the newly created node, including when zoomed out.

# Important Notes
- Camera is panned also if the node is only partially visible, or if there's not enough free space visible around the node. The specific amount of free space that needs to be visible around a newly created node is configured in the theme.
- If the screen area is so small that the node cannot be fully fit in it (either horizontally or vertically), showing the left and top boundaries of the node's area takes priority over showing the corresponding opposite edges.
Initial work restructuring the `Database.connect` API
- New SQLite API with support for InMemory.
- Updated PostgreSQL API with SSL and Client Certificate Support.
- Updated Redshift API.
# Important Notes
Follow up tasks:
- PostgreSQL SSL additional testing.
- Driver version updating.
- `.pgpass` support.
Implement simple placeholder icons for all entry kinds supported in the Suggestion Database. The icons are planned to be used in Component Browser as default icons for entries. This is intended to allow visually distinguishing different entry kinds.
The following additional fixes and tweaks are applied:
- Icons previously using only 1 color from the theme now use the color provided through shape parameters instead.
- The `data_science` and `network` icons now use only the 2 colors provided through shape parameters.
- The `join` icon has its shape and colors modified and uses only the 2 colors provided through shape parameters.
- The demo scene now parametrizes icon shapes using colors from the Component Browser Design Doc.

Make the local scope components available to the Component Browser through `component::List` (previously known as "Hierarchical Action List").

# Important Notes
- Note: the PR description does not include a screencast due to the changes in this PR not having any visual effect at this moment. The result of this PR's changes would be only observed in the Component Browser, but the Component Browser is not merged yet. As described in the task's Acceptance Criteria, the changes in this PR are currently only covered by tests.
- The `component::group::Data::new_empty_visible` constructor was renamed to `from_name_and_id` and changed to set the `visible` field to a default value. All known code paths appear to call the `update_sorting_and_visibility` method before checking the value of the `visible` field, so setting the value to `true` when creating the object does not seem needed.

Truffle is using [MultiTier compilation](190e0b2bb7) by default since 21.1.0. That mean every `RootNode` is compiled twice. However benchmarks only care about peak performance. Let's return back the previous behavior and compile only once after profiling in interpreter.
# Important Notes
This change does not influence the peak performance. Just the amount of IGV graphs produced from benchmarks when running:
```
enso$ sbt "project runtime" "withDebug --dumpGraphs benchOnly -- AtomBenchmark"
```
is cut to half.
Try following enso program:
```
main =
here.debug
foreign js debug = """
debugger;
```
it crashes the engine with exception:
```

`AtomBenchmarks` are broken since the introduction of [micro distribution](https://github.com/enso-org/enso/pull/3531). The micro distribution doesn't contain `Range` and as such one cannot use `1.up_to` method.
# Important Notes
I have rewritten enso code to manual `generator`. The results of the benchmark seem comparable. Executed as:
```
sbt:runtime> benchOnly AtomBenchmarks
```

This PR adds sources for Enso language support in IGV (and NetBeans). The support is based on TextMate grammar shown in the editor and registration of the Enso language so IGV can find it. Then this PR adds new GitHub Actions workflow file to build the project using Maven.
- Remove `from_xls` and `from_xlsx`.
- Add `headers` support to `File_Format.Excel`.
- Altered default read for Excel to be the first sheet.
- Altered behavior so that single cells grow down and right when reading sheet.
- Altered `Excel_Range` so knows if single cell or 1x1 range address.
# Important Notes
- Renamed `Range` to `Cell_Range` to avoid name clash.
A semi-manual s/this/self appied to the whole standard library.
Related to https://www.pivotaltracker.com/story/show/182328601
In the compiler promoted to use constants instead of hardcoded
`this`/`self` whenever possible.
# Important Notes
The PR **does not** require explicit `self` parameter declaration for methods as this part
of the design is still under consideration.
This PR merges existing variants of `LiteralNode` (`Integer`, `BigInteger`, `Decimal`, `Text`) into a single `LiteralNode`. It adds `PatchableLiteralNode` variant (with non `final` `value` field) and uses `Node.replace` to modify the AST to be patchable. With such change one can remove the `UnwindHelper` workaround as `IdExecutionInstrument` now sees _patched_ return values without any tricks.
Changelog:
- Describe the `EditKind` optional parameter that allows enabling engine-side optimizations, like value updates
- Describe the `text/openBuffer` message required for the lazy visualizations feature
This introduces a tiny alternative to our stdlib, that can be used for testing the interpreter. There are 2 main advantages of such a solution:
1. Performance: on my machine, `runtime-with-intstruments/test` drops from 146s to 65s, while `runtime/test` drops from 165s to 51s. >6 mins total becoming <2 mins total is awesome. This alone means I'll drink less coffee in these breaks and will be healthier.
2. Better separation of concepts – currently working on a feature that breaks _all_ enso code. The dependency of interpreter tests on the stdlib means I have no means of incremental testing – ALL of stdlib must compile. This is horrible, rendered my work impossible, and resulted in this PR.

This PR implements a new selection box that will replace an old (not really working) one in the component browser. The old selection box wasn't working well with the headers of the component groups, so we were forced to make a much harder implementation.
The new implementation duplicates some visual components and places them in a separate layer. Then, a rectangular mask cuts off everything that is not "selected". This way:
- We have more control over what the selected entries should look like.
- We can easily support the multi-layer structure of the component groups with headers.
- We avoid problems with nested masks that our renderer doesn't support at the moment.
To be more precise, we duplicate the following:
- Background of the component group becomes the "fill" of the selection.
- Entries text and icons - we can alter them easily.
- Header background and header text. By placing them in separate scene layers we ensure correct rendering order.
https://user-images.githubusercontent.com/6566674/173657899-1067f538-4329-44f9-9dc2-78c8a4708b5a.mp4
# Important Notes
- This PR implements the base of our future selection mechanism, selecting entries with a mouse and keyboard still has several issues that will be fixed in the future tasks.
- The scrolling behavior will also be improved in future tasks. Right we only restrict the selection box position so that it never leaves the borders of the component group.
- I added a new function to `add` shapes to new layers in a non-exclusive way (we had only `add_exclusive`) before. I have no idea how we didn't use this feature before even though we mention it a lot in the docs.
- The demo scene restricts the position of the selection box for one-column component groups but does not for the wide component group.
Put information about Virtual Component Groups in the Hierarchical Actions List.
https://www.pivotaltracker.com/story/show/181865548
# Important Notes
- This PR implements the subtask 2 of 2 in the ["Virtual Component Groups in the Hierarchical Action List" task](https://www.pivotaltracker.com/story/show/181865548).
- Note: the PR description does not include a screencast due to the changes in this PR not having any visual effect at this moment. The result of this PR's changes would be only observed in the Component Browser, but the Component Browser is not merged yet. As described in the task's Acceptance Criteria, the changes in this PR are currently only covered by tests.
- Manual integration testing with the Engine showed that a response to an `executionContext/getComponentGroups` request is non-empty only after an `executionContext/executionComplete` message is received by the IDE. (See also [a discussion on Discord](https://discord.com/channels/401396655599124480/983669600854106112).) This was not known by the IDE team or documented before, and the existing code was modified to take this into account. The protocol docs are expected to be updated by the Engine team.
- A list of component groups looked up in the suggestion database is cached in the node searcher as an optimization.

This change makes sure that Runtime configuration of `runtime` is listed
as a dependency of `runtime-with-instruments`.
That way `buildEngineDistribution` which indirectly depends on
`runtime-with-instruments`/assembly triggers compilation for std-bits,
if necessary.
# Important Notes
Minor adjustments for a problem introduced in https://github.com/enso-org/enso/pull/3509
Remove a `Symbol`from the `SymbolRegistry` when its `SpriteSystem` is dropped.
This fixes the remaining buffer leak (after #3504) in https://www.pivotaltracker.com/story/show/181943457
# Important Notes
- The `SymbolRegistry` now assigns unique `SymbolId`s, so that we can tell if a `SymbolId` refers to a `Symbol` that has already been unregistered (this shouldn't happen, but it's not statically-obvious that it doesn't, so if it occurs we shouldn't misbehave).
- Also fix a bug in how `buffer_count` was tracked (we were decrementing more than incrementing!).
- Removed `select` method.
- Removed `group` method.
- Removed `Aggregate_Table` type.
- Removed `Order_Rule` type.
- Removed `sort` method from Table.
- Expanded comments on `order_by`.
- Update comment on `aggregate` on Database.
- Update Visualisation to use new APIs.
- Updated Data Science examples to use new APIs.
- Moved Examples test out of Tests to own test.
