Fixes#5807
When implementing [cached icons in the Component Browser](#5779), I assumed pixel_ratio may be only integral (1.0 on normal machines and 2.0 on Retina), but I forgot Windows by default scales its UI by 1.25, breaking the icons entirely.
Added support for named arguments in IDE.
https://user-images.githubusercontent.com/919491/223681303-4c716639-d06e-4e33-aa22-6ebca2801b01.mp4
Named arguments are now recognized in node expressions. The function argument placeholders are rendered around series of named arguments. Insertion and deletion of arguments either by connection dragging or by widget selection will cause arguments around to be rewritten into appropriate form, such that the meaning of the expression doesn't change. We no longer need to introduce any wildcards (`_`) in argument positions when editing an argument list of a resolved method.
For unresolved function calls, the old behaviour remains, as we don't have data about argument names or their desired order.
This change downgrades hashing algorithm used in caching IR and library bindings to SHA-1. It is sufficient and significantly faster for the purpose of simple checksum we use it for.
Additionally, don't calculate the digest for serialized bytes - if we get the expected object type then we are confident about the integrity.
Don't initialize Jackson's ObjectMapper for every metadata serialization/de-serialization. Initialization is very costly.
Avoid unnecessary conversions between Scala and Java. Those back-and-forth `asScala` and `asJava` are pretty expensive.
Finally fix an SBT warning when generating library cache.
Closes https://github.com/enso-org/enso/issues/5763
# Important Notes
The change cuts roughly 0.8-1s from the overall startup.
This change will certainly lead to invalidation of existing caches. It is advised to simply start with a clean slate.
This PR changes build script's `ide watch` and `ide start` commands, so they don't use `electron-builder` to package. Instead, they invoke `electron` directly, significantly reducing time overhead.
`ide watch` will now start Electron process, while continuously rebuilding gui and the client in the background. Changes can be puilled by reloading within the electron, or closing the electron and letting it start once again. To stop, the script should be interrupted with `Ctrl+C`.
This change adds serialization and deserialization of library bindings.
In order to be functional, one needs to first generate IR and
serialize bindings using `--compiled <path-to-library>` command. The bindings
will be stored under the library with `.bindings` suffix.
Bindings are being generated during `buildEngineDistribution` task, thus not
requiring any extra steps.
When resolving import/exports the compiler will first try to load
module's bindings from cache. If successful, it will not schedule its
imports/exports for immediate compilation, as we always did, but use the
bindings info to infer the dependent modules.
The current change does not make any optimizations when it comes to
compiling the modules, yet. It only delays the actual
compilation/loading IR from cache so that it can be done in bulk.
Further optimizations will come from this opportunity such as parallel
loading of caches or lazily inferring only the necessary modules.

Fixes#5188
Added a new method `ShapeOps::recolorize` which changes color depending on values on r, g, b channels. It should be explained more in the docs. It will allow us using colored cached icons in the Component Browser.
Fixes#5023
This PR adds the ability to add a parameter to shapes defined, with `shape!` macro being a reference to a cached shape.
The API and results may be read [in the example scene](33b6f5937e/lib/rust/ensogl/example/cached-shape/src/lib.rs)
It also contains many other changes, required to have it working:
* We render cached shapes to texture in a different mode than normal shapes: the alpha channel is replaced with information about signed distance. That allows us using cached shapes as normal shapes, i.e. translate them, add to other shapes etc.
* We initialize and arrange shapes as a part of Word initialization, not in pass.
* We keep and blend colors in RGBA instead of LCHA - this is preparation for replacing colors in the next task, and also speeds up our shaders a bit.
The code was refactored in the process: the cached-shape related things were moved to a single module.
Visualizations closing right after opening was caused by the GUI being unresponsive during loading of some visualizations. This caused the timer for measuring the time between space bar press and space bar release to be inflated. The delayed events triggered the "visualization preview mode”, thus closing the visualization has it seemed that the space bar was held down, even though the events just arrived with some delay.
The problem is mitigated by considering the number of frames that have passed between the space and down and the space bar up event, instead of just the wall clock time. If the number of frames is too low, this indicates that frames were dropped to the time is inflated.
Fixes https://github.com/enso-org/enso/issues/5223
Fixes an error in our scoring algorithm for computing match scores. It now correctly computes scores for patterns that are trailing the target text and ranks patterns at the end of the target text higher than patterns in the middle of the target text.
Closes #4965 (for now).

In cloud we want to allow users to create new project from the template. List of templates is a bit outdated and doesn't contain all from the https://github.com/enso-org/project-templates. This PR simply adds missing ones
A combination of commands triggered separate compilation that only recompiled part of builtins. A mechanism that workaround annotation processor's problems with separate compilation was updated to include changes from https://github.com/enso-org/enso/pull/4111. This was pretty tough to find given the rather unusual circumstances in CI.
# Important Notes
This eliminates the _random_ failures in CI related to separate compilation.
To reproduce a specific set of steps has to be executed:
```
sbt> all buildEngineDistribution engine-runner/assembly runtime/Benchmark/compile language-server/Benchmark/compile searcher/Benchmark/compile
(exit sbt)
sbt> test
```
Expressions returning polyglot values were not reporting the type of the result because we have to do additional magic that infers the correct Enso type. Since this is exactly what `TypeOfNode` does, I re-used the logic.
Straightforward solution failed in tests because of assertions:
```
[enso] WARNING: Execution of function main failed (Invalid library usage. Cached library must be adopted by a RootNode before it is executed.).
java.lang.AssertionError: Invalid library usage. Cached library must be adopted by a RootNode before it is executed.
```
That is why this PR replaces `ExecutionEventListener` with `ExecutionEventNodeFactory`.
# Important Notes
Usage of `TypeOfNode` for programs that **do not** import stdlib means that we report types that do not involve stdlib e.g.
`Standard.Builtins.Main.Integer` instead of `Standard.Base.Data.Numbers.Integer`. While surprising, this is correct and I would say desirable. While reviewing the code, notice the difference in expectations in our runtime tests.
Implementation of https://www.pivotaltracker.com/story/show/184012743https://user-images.githubusercontent.com/919491/214082311-cf49e43c-1d1f-4654-903c-a4224cd954d8.mp4
This is also a step towards more general widget support. The widget metadata is queried using `Meta.get_annotation` method through a dedicated visualization. For now only `Single_Choice` case is handled, and always all suggestions are is returned.
# Important Notes
There are limitations as to which node segments receive a widget. Only chain method calls are supported now (`thing.method` syntax), and only outside of lambda scope. Widgets in lambdas will require support for visualisations of lambda subexpressions, which is currently missing in the engine. The IDE technically tries to place the widgets there, but the data never arrives. It should work once the engine support is added.
This PR includes a mock for `Meta.get_annotation` call that only supports `Table.at` method. Real implementation is a separate task that is already in progress.
This PR contains the first implementation of `cached_shape!` macro, which should help us with reducing draw calls in our application.
```rust
mod icon1 {
use super::*;
ensogl_core::cached_shape! { 32 x 32;
() {
let shape = Circle(16.px()).fill(color::Rgba::green());
shape.into()
}
}
}
mod icon2 {
use super::*;
ensogl_core::cached_shape! { 202 x 312;
() {
let shape = Rect((200.px(), 310.px())).fill(color::Rgba::red());
shape.into()
}
}
}
```
The above code creates two cached shapes. They are similar to normal shapes (created with `shape!` macro), except that:
1. they do not allow for any parametrization
2. They are rendered at the application start to the special texture with cached shapes.
The texture will be used in next PRs to cache all Component Browser icons on the texture and draw all of them just by single, fast draw call. In the future, more shapes can be cached, further reducing draw calls and making them simple.
# Important Notes
The results are presented in `cached_shapes` debug scene: there are two shapes displayed and a scaled cached texture is displayed in the background.
In order to investigate `engine/language-server` project, I need to be able to open its sources in IGV and NetBeans.
# Important Notes
By adding same Java source (this time `package-info.java`) and compiling with our Frgaal compiler the necessary `.enso-sources*` files are generated for `engine/language-server` and then the `enso4igv` plugin can open them and properly understand their compile settings.
In addition to that this PR enhances the _"logical view"_ presentation of the project by including all source roots found under `src/*/*`.
https://github.com/enso-org/enso/pull/3764 introduced static wrappers for instance methods. Except it had a limitation to only be allowed for types with at least a single constructor.
That excluded builtin types as well which, by default, don't have them. This limitation is problematic for Array/Vector consolidation and makes builtin types somehow second-citizens.
This change lifts the limitation for builtin types only. Note that we do want to share the implementation of the generated builtin methods. At the same time due to the additional argument we have to adjust the starting index of the arguments.
This change avoids messing with the existing dispatch logic, to avoid unnecessary complexity.
As a result it is now possible to call builtin types' instance methods, statically:
```
arr = Array.new_1 42
Array.length arr
```
That would previously lead to missing method exception in runtime.
# Important Notes
The only exception is `Nothing`. Primarily because it requires `Nothing` to have a proper eigentype (`Nothing.type`) which would messed up a lot of existing logic for no obvious benefit (no more calling of `foo=Nothing` in parameters being one example).
This PR implements HTML generation from documentation IR for all suggestion database entries and replaces the old documentation panel with a newer one.
Additional adjustments to the looks of the documentation would be applied separately in a future PR. This PR focuses on the fastest possible delivery of a usable documentation panel. We want to test it in real-world use cases and gather feedback for future improvements.

# 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.
Introduces unboxed (and arity-specialized) storage schemes for Atoms. It results in improvements both in memory consumption and runtime.
Memory wise: instead of using an array, we now use object fields. We also enable unboxing. This cuts a good few pointers in an unboxed object. E.g. a quadruple of integers is now 64 bytes (4x8 bytes for long fields + 16 bytes for layout and constructor pointers + 16 bytes for a class header). It used to be 168 bytes (4x24 bytes for boxed Longs + 16 bytes for array header + 32 bytes for array contents + 8 bytes for constructor ptr + 16 bytes for class header), so we're saving 104 bytes a piece. In the least impressive scenarios (all-boxed fields) we're saving 8 bytes per object (saving 16 bytes for array header, using 8 bytes for the new layout field). In the most-benchmarked case (list of longs), we save 32 bytes per cons-cell.
Time wise:
All list-summing benchmarks observe a ~2x speedup. List generation benchmarks get ~25x speedups, probably both due to less GC activity and better allocation characteristics (only allocating one object per Cons, rather than Cons + Object[] for fields). The "map-reverse" family gets a neat 10x speedup (part of the work is reading, which is 2x faster, the other is allocating, which is now 25x faster, we end up with 10x when combined).
This is a followup to https://github.com/enso-org/enso/pull/4046#pullrequestreview-1248164069.
- Compiler job cancelation is now handled - the cache entry will be cleared or the job will be resumed if there is still demand.
- The compilation awaiting process has been rewritten to not use polling. The "read cache" job is now only used to dispatch known valid reads. It is always completed within a single run cycle.
- Changed shader struct to use `ImString` for storing code, so it can be cheaply cloned. This is now common, as we are cloning it from cache.
`@` should not be legal to use as a binary operator. I accepted it in the parser because it occurred in the .enso sources, but it was actually used to create a syntax error to test error recovery.

The fix consists of two parts:
1. All the "review-apply" and "store temporary md" actions in the searcher controller are now guarded by an ignored transaction.
2. Because some of the temporary state may reach the UR frames assigned to other actions, added a bunch of code for removing all temporary expressions from the code and use it after restoring a frame. We may consider using it after project load as well.
### Important Notes
Added a useful method "log_err" to ResultOps (so every Result will have those).
Logging: Replace tracing with an efficient logging implementation, with 0-runtime cost for disabled log levels. (https://www.pivotaltracker.com/story/show/183755412)
Profiling: Support submitting `profiler` events to the User Timing Web API, so that measurements can be viewed directly in the browser. (https://www.pivotaltracker.com/story/show/184003550)
# Important Notes
Logging interface:
- The macros (`warn!`, etc.) now take standard `format_args!` arguments (the tracing implementations accepted a broader syntax).
- Compile-time log levels can now be set through the CLI, like so:
`./run ide start --log-level=trace --uncollapsed-log-level=info`
Profiling:
- The hotkey Ctrl+Alt+Shift+P submits all `profiler` events logged since the application was loaded to the Web API, so that they can then be viewed with the browser's developer tools. Note that standard tools are not able to represent async task lifetimes or metadata; this is a convenient interface to a subset of `profiler` data.
- As an alternative interface, a runtime flag enables continuous measurement submission. In the browser it can be set through a URL parameter, like http://localhost:8080/?emit_user_timing_measurements=true. Note that this mode significantly impacts performance.
Fixes an error when the logger processes NPE:
```
[internal-logger-error] One of the printers failed to write a message: java.lang.NullPointerException
```
Fixes https://www.pivotaltracker.com/story/show/184216698
Reduced impact of node dropdown widgets on load times by deferring creation of grid views until each widget is opened. This also improves node editing time, as the dropdowns are not recreated immediately.
This approach of lazy initialization now caused a significant lag when opening the dropdown. Two major causes of the lag spike is glyph generation (msdfgen, `new_glyph`) and shader compilation (happened every time, because each dropdown has unique layer stack). To reduce the impact of that, the shader compiler now caches the shaders based on generated shader source. Glyph creation hasn't been changed and is still slow. The startup performance is now roughly where it was before introducing widgets.

Added a dropdown widget to graph node for all span tree nodes that have tag values present. When an option is selected, the controller receives a partial expression update, which targets specific crumbs of the expression (similar to how edge endpoint updates work).
https://user-images.githubusercontent.com/919491/210219931-8ae418fd-3ac4-44a5-abea-9e670f15cdf9.mp4
# Important Notes
Right now the dropdown widget is recreated every time the node is edited, including a dropdown option being selected. This causes it to close every time. I wanted to get around that by diffing span trees, but I wasn't able to do it in useful way. Additionally, current implementation of node input expression view heavily relies on being reinitialized from scratch every time. This led to more necessary changes than I was comfortable with for this task. I believe it will be easier to implement it as part of more complete widget support, especially after dynamic data support, as we will have proper widget type information.
Implements https://www.pivotaltracker.com/n/projects/2539304/stories/184023380
Dropdown component. Planned to be used in nodes as a single and multiple selection widget, both for static and dynamically loaded values. Initial support is focused on static data, with limited support for dynamic sources. Notably, loading states are not supported yet. Full support for that is planned to be added later with widget lazy-loading.
- Supports single and multiple selections.
- Dedicated API for providing a static list of all entries.
- Range-based query API for dynamically loading data as it is scrolled (only basic support - will need more work for proper async lazy-loading).
- Internal entry cache and query batching to avoid querying data one by one (the batching for now is very basic, will have to be improved for proper lazy-loading).
- Automatic dropdown width adjustment based on the entry label lengths, up to a set max allowed value.
- Open and close animation.
- Keyboard support for focusing and selecting entries.
# Important Notes
Implementing the dropdown on top of grid-view have uncovered some assumptions around grid-view layers. It was assumed to always be a part of the component browser. Removing that assumption required a mechanism for propagating camera update information through layer tree. This is now implemented using a `camera_parent` layer field. Ideally each layer should simply have at most a single parent, and camera inheritance would follow that. That refactor turned out to be quite involved, so right now the simpler temporary solution is introduced in order to not delay this PR further.
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`.
This PR provides a visual indication of whether the project's current state differs from the most recent snapshot saved in the VCS. The project name displayed in the IDE changes to a darker text to indicate that the VCS snapshot is outdated, and back to a lighter text when the current project state corresponds to the last saved VCS snapshot.
https://user-images.githubusercontent.com/117099775/208088438-20dfc2aa-2a7d-47bf-bc12-3d3dff7a4974.mp4
The outdated project snapshot indicator is set when:
* A node is moved.
* A node is added or removed.
* The text editor is used to edit the text.
* The project is auto-saved, and the auto-saved project state does not correspond to the last saved snapshot in the VCS.
The outdated project snapshot indicator is cleared when:
* A new project snapshot is successfully saved using `ctrl+s`.
* The project is auto-saved, and the auto-saved project state is confirmed to correspond to the last saved snapshot in the VCS. This occurs, for example, when a project change is undone and the project is reverted to the last saved snapshot state.
The auto-save events do not occur immediately after a project change but have a short delay, thus the VCS status update is affected by the same delay when triggered by an auto-save event.
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.
This fixes https://www.pivotaltracker.com/story/show/182844611
This is an enhancement of the `Slider` component implemented in #3852. It adds the following features:
* Tooltips and precision change hints
* Selectable slider limit behaviors
* Textual slider value editing
* Vertical slider layout
#### Tooltips
An information tooltip can now be added to a slider, it is shown when the mouse hovers over the component. Additionally, a pop-up indicating the slider's precision appears when the slider's precision has been adjusted.
https://user-images.githubusercontent.com/117099775/206148098-3b4dc059-18aa-4200-9ee0-5d4382363810.mp4
#### Slider limits
The previous slider implementation clamped the adjusted value to the slider's minimum/maximum limits. Now the following behaviors are available:
* Hard limits: Clamp the value to a range within the slider's limits.
* Soft limits: The value can extend beyond the slider's limits. When this occurs, an overflow indicator will be displayed on the side of the limit that is exceeded.
* Adaptive limits: The value can extend beyond the slider's limits. When this occurs, the exceeded limit will temporarily be adjusted to double the slider's range. This will be performed iteratively until the value falls within the extended limits. When a limit is extended and the value is adjusted to fit a smaller range, the extended limit will be iteratively halved until only the necessary range is covered. The slider's extended limits will never shrink to a range smaller than the original range.
These behaviors can be set to the lower and upper limits of a slider independently.
https://user-images.githubusercontent.com/117099775/206148139-6149c91d-ef49-4e2d-97f6-71084f52591c.mp4
#### Textual editing
The slider's value can now be entered through a text input field. Double-click to edit the slider's current value. To confirm the edit press `enter`, or press `escape` to cancel the edit. If an invalid value is entered on confirmation the slider will revert to its value before the edit. The slider's precision will be adjusted based on the number of decimal places of the value entered.
https://user-images.githubusercontent.com/117099775/206148170-d3fa4c82-6e73-4b1c-9be9-cb99979f7b70.mp4
#### Vertical layout
The slider component now supports a vertical layout. In this case value adjustment is performed by a vertical mouse movement, and a horizontal movement adjusts the slider's precision. The slider's track now fills the component in a vertical direction, and the slider's label is displayed near the top end of the component.
https://user-images.githubusercontent.com/117099775/206148211-0f176aaf-bc1b-45e2-afd7-0d28391aafcb.mp4
#### Scroll bar mode
The slider component supports two indicator modes:
* `Track`: The component is filled with a colored bar from the lower limit (empty) to the upper limit (full) dependent on the slider's value.
* `Thumb`: The component contains a rounded indicator that moves along the slider from one end to the other, indicating the slider's value proportionally to the slider's limits. The width of the indicator is configurable.
In addition, the value text, text entry, and precision adjustment can be turned off to provide a scroll bar appearance when used with the `Thumb` indicator.

#### Example scene shortcuts
The example scene contains two shortcuts in order to evaluate the dynamic addition and removal of the slider components:
* `CTRL+D` drops all the slider components that are added to the scene.
* `CTRL+A` adds a new set of example slider components to the scene.

# Important Notes
The root cause of the issue was a missing deref before `flavor()` call. The autoderef doesn't work there, because the `ShapeSystemFlavorProvider` trait is implemented for all types, including `Ref`. We should reconsider if blanket default impl is a good idea, as this is a very scary footgun.
Apart from that, the cleanup of layer elements was not handling systems with same ID but different flavors correctly. That could cause text to disappear when given layer had text of multiple fonts, and all shapes of one of them got removed. Now the element is removed from layer only when all systems sharing given system ID have no more instances to render.
* 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.
This PR is a draft PR while I learn EnsoGL. The eventual goal is to implement the projects list portion of the cloud dashboard in this PR. This PR will implement part of https://www.pivotaltracker.com/n/projects/2539513/stories/183557950
### Important Notes
This PR is still really rough and contains a lot of hacks & hard-coded values. The FRP usage is also likely to be suboptimal and need fixing.
Fix issues noted here: https://github.com/enso-org/enso/pull/3678#issuecomment-1273623924
- Time complexity of an operation during line-redrawing scaled quadratically with number of lines in a change; now linear.
- Time complexity of adding `n` selections to a group was `O(n^2)`. Now it is `O(n log n)`, even if the selections are added one by one.
Also fix a subtle bug I found in `Group::newest_mut`: It returned a mutable reference that allowed breaking the *sorted* invariant of the selection group. The new implementation moves the element to invalidated space before returning a reference (internally to `LazyInvariantVec`), so that if it is mutated it will be moved to its correct location.
### Important Notes
New APIs:
- `NonEmptyVec::extend_at` supports inserting a sequence of elements at a location, with asymptotically-better performance than a series of `insert`s. (This is a subset of the functionality of `Vec::splice`, a function which we can't safely offer for `NonEmptyVec`).
- `LazyInvariantVec` supports lazily-restoring an invariant on a vector. For an invariant such as *sorted* (or in this case, *sorted and merged*), this allows asymptotically-better performance than maintaining the invariant with each mutation.
This PR fixes the `code_to_insert` method of entry to insert valid code according to the newest language version. Also created a separate method for getting imports required by given entry.
Now, method entries do not add imports (except when they are extensions), and are insterted with place for this type `_.method`. Static methods and constructors are inserted with the type name, and proper import for type is added.
There are some additional work done:
* The ReferentName and NormalizedName were removed, as we are now case-sensitive.
* All QualifiedName structures were replaced with new one in `name` module, as there is no longer functional difference between type qualified name and module qualified name.
* The QualifiedName structure removes "Main" module segment where it is not necessary, thus simplifying our code base and avoiding potential issues.
* Added macro `mock_suggestion_database` which should make creating consistent mocks of SuggestionDatabase much simpler.
* Fixed bug where the visualization preview show no value for some time.

# Important Notes
The tests in controller/searcher.rs file are not of the best quality, but those will be overhauled anyway when implementing my next task.
This `Slider` component allows adjusting a numeric value with the mouse. The value is increased or decreased by clicking on the component and dragging it to the left or right.
The `Slider` has a configurable default value. `Ctrl`+clicking on the component resets its value to that default. When the value is moved away from the default, the value is printed in **bold**.
The `Slider` precision is increased or decreased by clicking the component and dragging upward or downward. This precision influences how quickly the value changes when the mouse moves horizontally, the steps in which the value is incremented or decremented, and the number of digits used to display the value. There is a margin around the component within which the precision is not changed. Beyond this margin, the precision is increased or decreased in powers of 10 (e.g. `0.1` -> `0.01` -> `0.001` when moving the mouse downwards, or `0.1` -> `1.0` -> `10.0` when moving the mouse upwards). The margin and distance between consecutive steps along the vertical axis are configurable.
The value of the `Slider` is limited to a configurable range, and cannot be adjusted beyond that range. A colored bar fills the component to indicate the current value within the range.
#### Video demonstration
https://user-images.githubusercontent.com/117099775/202244982-2f6f419d-7281-41f6-8607-7e492ad25b46.mp4
#### Future additions
This is the first iteration of the `Slider` component. Additional features are planned for the future:
* Textual editing of the value.
* Improved visual feedback on precision changes.
* Additional out-of-range behaviors.
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).
This change adds support for Version Controlled projects in language server.
Version Control supports operations:
- `init` - initialize VCS for a project
- `save` - commit all changes to the project in VCS
- `restore` - ability to restore project to some past `save`
- `status` - show the status of the project from VCS' perspective
- `list` - show a list of requested saves
# Important Notes
Behind the scenes, Enso's VCS uses git (or rather [jGit](https://www.eclipse.org/jgit/)) but nothing stops us from using a different implementation as long as it conforms to the establish API.
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.
Ensure all tokens from the input are represented in trees resulting from invalid inputs--tests now cover every reachable code line that creates an `Invalid` node. (Also implemented stricter validation, mainly of `import`/`export` statements.)
See: https://www.pivotaltracker.com/story/show/183405907
Another set of improvements extracted from #3611. This time it includes a fix to the Rust part of the parser.
# Important Notes
After digging into metadata parsing I realized the positions used to query the BTree data structure are wrong. This PR tries to address that by re-arranging the order of serialized fields and passing `startCode` and `endCode` locations in.
Originally I though I need changes on the Rust side to support `in` operator. Turned out I can do that just with changes on the Java side.
Qualified names in imports were missing UUIDs. Fixed now.
Split `HasOutputTypeLabel::output_type_label` method implementation non-generic part into a separate function. This significantly reduces compile time without risking any performance regressions. That function is currently only used for debug network visualization using graphviz, but still contributed a significant compilation time.
I've made a single attempt to profile the compiler itself, and it turned out that the compiler spent a significant amount of time trying to resolve `Pattern` implementation for closures in that method. Each of those also had to separately go through codegen and optimization. That happened for each node type in the codebase, per crate. Moving that into separate non-inline function removed all those unnecessary duplicates from. I also took this opportunity to rewrite that small piece of parsing to make it a bit cleaner.
The method of measurement is explained here: https://blog.rust-lang.org/inside-rust/2020/02/25/intro-rustc-self-profile.html
In this specific case, I've used `self-profile` to generate a profile for all crates, then used `crox` and [perfetto](https://ui.perfetto.dev/) to analyze the output.
This also shows a pattern to be aware of - using closures in generic context forces the compiler to make a separate closure type per each instantiation, even if that closure doesn't close on anything and could be a static function. This in effect forces even more instantiations or unnecessary type resolutions for all code paths that touch that closure. Using static functions or separating the non-generic part away in those cases would likely continue to help with compile times and file size.

# Important Notes
There was [a discussion](https://discord.com/channels/401396655599124480/1036562819644141598) about proper location of the library. It was concluded that _"there's no functional difference between a dylib and a jar."_ and as such the library is placed in `component` folder.
Currently the old parser is still used for parsing. This PR just integrates the build system changes and makes us ready for smooth flipping of the parser in the future as part of #3611.
Wrap big and commonly copied `Application` struct into `Rc` to avoid large structure sizes for all widgets.
The `Application` struct by itself takes 704 bytes, measured by `size_of::<Application>()`. This structure is very often directly copied into components and widgets. Most notably, the generic `Widget` struct contains it. There are also cases, where structs (especially various `Model`s) contain multiple other child widgets directly, and end up indirectly copying the application multiple times.
All of `Application` clones are logical references (via `CloneRef`), so wrapping it into extra `Rc` doesn't change semantics in any way, but makes all structs that clone it way smaller. This reduces the amount of `memcpy`s and overall volume of allocated memory.
Measurement of a few example structs:
Before change:
```
size_of Application: 704 B
size_of Scrollbar: 712 B
size_of Scrollbar Model: 1576 B
```
After change:
```
size_of Application: 4 B
size_of ApplicationData: 704 B
size_of Scrollbar: 12 B
size_of Scrollbar Model: 176 B
```
Ideally we would not need to clone application reference into each component, but that's out of scope of this PR since it requires a lot more effort.
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.
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.

This PR fixes an IDE freeze introduced by https://github.com/enso-org/enso/pull/3732 and reimplements reverting edited nodes to their previous state.
The cause of the IDE freeze is quite interesting. A detailed investigation is available [here](https://gist.github.com/vitvakatu/785e34881368b8cfda61715d7543cbd0).
The graph editor needs to update the Presenter state only if the user is editing the node. Before this PR, the graph editor notified the Presenter with a visual representation of the node content instead of code expression. It caused inconsistency between the states of the controller and Presenter and caused severe performance issues.

# Important Notes
- ~~There is a more complex alternative solution – it requires refactoring of the `component::node::input::area` module. The Presenter can be notified with `expression.code` changes, not `expression.viz_code`. I found a simpler solution (`.gate(&edit_mode)`), which has the same effect but does not require additional refactoring.~~ Said solution is implemented in a separate commit
We've had an old attempt at integrating a Rust parser with our Scala/Java projects. It seems to have been abandoned and is not used anywhere - it is also superseded by the new integration of the Rust parser. I think it was used as an experiment to see how to approach such an integration.
Since it is not used anymore - it make sense to remove it, because it only adds some (slight, but non-zero) maintenance effort. We can always bring it back from git history if necessary.

# Important Notes
- The "Label" visual component was fixed. Previously, the width calculation of the background was not synchronized correctly with the text width. As a result, a zero-width background was displayed when a Label was shown for the first time.
There is one place in code, where we can potentially panic on double borrow, because the drop routine is done while having data borrowed.
# Important Notes
The issue was easily reproducible on @Frizi machine.
Another part of #3611 ready for integration into `develop` branch.
# Important Notes
Test `org.enso.compiler.EnsoCompilerTest.testTestGroup` is ignored as it has problems with source offsets - identifiers don't have the appropriate names due to `Tree.codeRepr()` being _off_.
- Special precedence rules for case-of so that `:` operator works without parens or nospace-grouping.
- Support an old-lambda syntax: `x->x-> x`. According to the usual rules, the first nospace group would be parsed as an operator section. The expression now parses as a lambda that contains a lambda.
- Match old parser treatment of # in doc comments.
- Tweak precedence so (a : B = c) works.
- Documented constructors.
- 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.
This PR introduced an overhauled Component List Panel implementation, making use of the efficient EnsoGL grid view component. Also, it delivers a couple of new features:
* A part of the new design: there are no more section headers in grid, instead groups are "glued" together. The local scope section is under "popular" (old "favorites").
* The keyboard management inside grid works.
* there is a mouse hover highlight
* selecting the lowest entry in section when jumping with navigation bar.
* accepting input as-is with cmd/ctrl + Enter.

### Important Notes
**What is not implemented:**
* [Focus management between panels.](https://www.pivotaltracker.com/story/show/180872763) The grid is always focused. To accept the current input, use ctrl+Enter shortcut.
* [Proper handling of selection when having empty space on the right and pressing right arrow.](https://www.pivotaltracker.com/story/show/183487880)
* When entering a module, its name is not added to the input as described in the design doc. Will be a part of [this User Story](https://www.pivotaltracker.com/story/show/181058321).
**Known issues**
* [the selection, especially in the local scope section, has sometimes an undesirable offset](https://www.pivotaltracker.com/story/show/183487730). The cause is known, but not so easy to fix.
* The inserted nodes are often producing errors. The Browser's inherits the outdated understanding of the language from old Node Searcher, and it does not include new form of imports, static methods etc. Those all will be fixed as a part of [this User Story](https://www.pivotaltracker.com/story/show/181058321).
* The performance is improved, but still not ideal, due to problems in [text areas](https://www.pivotaltracker.com/story/show/183406745).
* To scroll the documentation panel, you must first click on it.
- Implement macro-contexts-lite (`from` is now only a keyword at the beginning of a line)
- Support special nospace-group handling for old lambdas (so expressions like this work: `x-> y-> x + y`)
- Fix a text-escape incompatibility
# Important Notes
- There is now an `OperatorFunction`, which is like a `Function` but has an operator for a name, and likewise an `OperatorTypeSignature`.

This PR implements the actual integration of the breadcrumbs panel with the component list panel. A special breadcrumbs controller (`controller::searcher::breadcrumbs`) is tracking the currently opened module with a list of its parents. The searcher presenter uses the API of the controller to sync the displayed list of breadcrumbs with the controller state.
https://user-images.githubusercontent.com/6566674/193064122-7d3fc4d6-9148-4ded-a73e-767ac9ac83f8.mp4
# Important Notes
- There is an `All` breadcrumb displayed at all times at the beginning of the list. It will be replaced with a section name as part of [Section Title on Component Browser's Breadcrumbs Panel](https://www.pivotaltracker.com/story/show/182610561) task.
- I changed the implementation of `project::main_module_id`, `project::QualifiedName::main_module`, and `API::main_module` so that they are logically connected which each other.
- I adjusted the Breadcrumbs View to avoid "appearance" animation glitches when opening new modules. `set_entries` was replaced with the `set_entries_from` endpoint.
When running the profiling run-graph and flamegraph demo scenes, if a profile file is not found in the directory served over http, fall back to generating demo data.
This PR disables the wasm-opt optimization in the crates that can be used as WASM entry points. Unfortunately, wasm-pack does not allow for disabling wasm-opt through a command line flag, so we have to disable it by setting an appropriate flag in each Cargo.toml.

This PR adds a possibility to generate native-image for engine-runner.
Note that due to on-demand loading of stdlib, programs that make use of it are currently not yet supported
(that will be resolved at a later point).
The purpose of this PR is only to make sure that we can generate a bare minimum runner because due to lack TruffleBoundaries or misconfiguration in reflection config, this can get broken very easily.
To generate a native image simply execute:
```
sbt> engine-runner-native/buildNativeImage
... (wait a few minutes)
```
The executable is called `runner` and can be tested via a simple test that is in the resources. To illustrate the benefits
see the timings difference between the non-native and native one:

# Important Notes
Notice that due to a [bug in GraalVM](https://github.com/oracle/graal/issues/4200), which is already fixed in 22.x, and us still being on 21.x for the time being, I had to add a workaround to our sbt build to build a different fat jar for native image. To workaround it I had to exclude sqlite jar. Hence native image task is on `engine-runner-native` and not on `engine-runner`.
Will need to add the above command to CI.
When a GridView is navigated using the keyboard, scroll it to display the newly selected entry.
https://www.pivotaltracker.com/story/show/182593635
#### Visuals
See below for a video demonstrating automatic scrolling of the GridView when arrow keys are pressed on the keyboard. The first video below shows the default scrolling behavior in a GridView without headers.
Note:
- When the Grid View is scrolled, the mouse hover highlight moves away from the mouse position. This is not a new regression, the behavior is the same in the `develop` branch (e.g. when scrolling using the mouse).
https://user-images.githubusercontent.com/273837/190183984-91f7808c-3606-43f8-bcda-ac4d5f84e00f.mov
The video below shows the behavior in a GridView with headers when the GridView is first scrolled to its top-left corner. The following guidance from the Design Doc is enabled and showcased:
> Users can change the selected component by pressing the arrow keys. The Focus does not move up if it does not have to (in most cases, the focus is located in the second row from the bottom). Instead, the component list scrolls down if there are enough entries.
https://user-images.githubusercontent.com/273837/189151546-e50aaf22-6f4d-41cb-809f-60038305745f.mov
The next video shows the behavior in the same GridView as in the previous example when the GridView is first scrolled away from any of its boundary entries. Notably, scrolling happens only when the selection is moved using the keyboard arrow keys, not when changing the selection using the mouse. This behavior is based on a discussion with @wdanilo on Discord.

# Important Notes
* The styling is not detailed yet due to time constraints (I want to move to integration this grid view to Component Panel List ASAP) and the fact that I could not get new mplus1 font working with text Area.

# Important Notes
- This PR implements an old interaction of the design of the component browser. The new design of the breadcrumbs can not be easily integrated into the current look of the component browser, so we would need to update styles later. It should be a relatively simple task. *The implementation uses color from the new design though. (but not fonts and sizes)*
- I found a bug in the grid view implementation that causes panics at runtime in some conditions. The reason is triggering FRP endpoints while constructing new entries. This issue is fixed in the PR.

#### Visuals
See below for videos showcasing GridView selection keyboard navigation in the `grid_view` debug scene. In the videos, messages in the Developer Console can be observed. When a keypress would result in the selection being moved out of the GridView, the selection is not moved and a message is emitted in the Developer Console instead, showcasing an FRP output signal emitted on such event. Please note that the videos are recorded with the tracing level changed to `DEBUG`. In a default build, the tracing level is set to `WARN`, and the messages visible in the videos are not displayed in the Developer Console.

The following video shows moving the selection between "regular" entries and header entries. It also shows a current usability limitation of the selection keyboard navigation feature, such that the Grid is not scrolled when the selection leaves the visible part of the Grid, and the selection may thus disappear from view.

# Important Notes
- Keyboard navigation only works when a GridView has focus.
- Selection keyboard navigation only works if the selection was already set to some entry beforehand.
- If keyboard navigation would move selection outside of the grid, the selection movement is canceled and an FRP event is emitted.
`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.
