```
from Standard.Base import all
main =
value = 1
case value of

_ -> IO.println "other"
```
# Important Notes
Had to write new `ExecCompilerTest` as comparing the AST with old compiler produced miserable results - the old AST wasn't ready for negative constants in `case of` at all.
Add `Test.with_clue` function similar to ScalaTest's [with_clue](https://www.scalatest.org/user_guide/using_assertions).
This is useful for tests where the assertion depends on context which is not clear from it's operands.
### Important Notes
Using with_clue changes `State Clue` which is extracted by the `fail` function.
The State is introduced by `Test.specify` when the test is not pending.
There should be no changes to the public API apart form the addition of `Test.with_clue`.
Apparently
```
git --git-dir .enso/.vcs log refs/heads/master
fatal: ambiguous argument 'refs/heads/master': unknown revision or path not in the working tree.
```
but
```
git --git-dir .enso/.vcs log HEAD
fatal: ambiguous argument 'refs/heads/master': unknown revision or path not in the working tree.
```
works just fine on Windows.
Added some safeguards to avoid propagating weird errors because of retrieving element from an
empty Option.
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.

#### 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.

#### 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.

#### 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.

#### 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.
The presence of `.git` in Enso's data directory (`.enso`), which should be under VCS as well, turned out to be really problematic. Git (and JGit) treat `.enso` as a submodule which prevents as from manual inspection of the repo. Additionally, every commit changed the submodule version, which in turn was reporting invalid/changed status always.
This change renames `.enso/.git` to `.enso/.vcs` which eliminates a lot of problems. Additionally, rather than doing `git add .` we selectively add files to the index, thus preventing most of the issues reported in the ticket.
This change also means that JGit's status needs to filter `.enso/.vcs` as those will be marked as untracked always.
# Important Notes
To manually test the status of the project's repo do
```
git --git-dir .enso/.vcs status
```
Using lambda instead of higher order function.
# Important Notes
Running:
```
sbt:runtime> benchOnly VectorBenchmarks.averageOverArrayProxy
```
speeds up from `0.038 ms/op` to `0.016 ms/op` on my computer. Which seems good enough.
Fixes bug in visualization of host polyglot values - `ExpressionNode` is only wrapped once Chrome inspector instrument is attached to the context. With this fix, when chromeinspector is attached (`enso --run --inspect ...`), all the host values are reinterpreted as text - the assumption is invalidated. But when running as language server, nothing is wrapped.
Fixes regression https://www.pivotaltracker.com/n/projects/2539304/stories/183895961
# 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.
Allow arbitrary expression evaluation in the chromeinspector console. Moreover, allow modifications of any variable in any stack frame.
# Important Notes
- Implement inline parsing in `EnsoLanguage.parse(InlineParsingRequest)`.
- Debugging experience is affected by this [bug in Truffle](https://github.com/oracle/graal/issues/5513), which causes NPEs when a host object gets into chromeinspector. I tried to implement a workaround, but it does not work all the time. Nevertheless, it should not matter that much - if there is a NPE in the debugger, you can just ignore it, as it should be concealed in the debugger and should not be propagted outside. See comments in the `docs/debugger`.
* 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.

No more `_Data` constructors!
Fixes the regression when IDE fails to create a project from template. Project name should start with an upper case letter to pass the server side validation.
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.
- Moved `Any`, `Error` and `Panic` to `Standard.Base`.
- Separated `Json` and `Range` extensions into own modules.
- Tidied `Case`, `Case_Sensitivity`, `Encoding`, `Matching`, `Regex_Matcher`, `Span`, `Text_Matcher`, `Text_Ordering` and `Text_Sub_Range` in `Standard.Base.Data.Text`.
- Tidied `Standard.Base.Data.Text.Extensions` and stopped it re-exporting anything.
- Tidied `Regex_Mode`. Renamed `Option` to `Regex_Option` and added type to export.
- Tidied up `Regex` space.
- Tidied up `Meta` space.
- Remove `Matching` from export.
- Moved `Standard.Base.Data.Boolean` to `Standard.Base.Boolean`.
# Important Notes
- Moved `to_json` and `to_default_visualization_data` from base types to extension methods.
Save a snapshot of the project directory to the VCS on `ctrl+s`. If the operation fails because the VCS was not initialized previously, it will try to initialize the VCS first and then save a snapshot.
Converting `Integer.parse` into a builtin and making sure it can parse big values like `100!`. Adding `locale` parameter to `Locale.parse` and making sure it parses `32,5` as `32.5` double in Czech locale.
# Important Notes
Note that one cannot
```
import Standard.Table as Table_Module
```
because of the 2-component name restriction that gets desugared to `Standard.Table.Main` and we have to write
```
import Standard.Table.Main as Table_Module
```
in a few places. Once we move `Json.to_table` extension this can be improved.
Disabling `musl` as it isn't capable to load dynamic library.

```
Is it OK, @radeusgd to disable `musl`? If not, we would have to find a way to link the parser in statically, not dynamically.
Implements https://www.pivotaltracker.com/story/show/183915527
Adds a common entry point to the `Benchmarks` test suite, so that all benchmarks can be run at once.
Usually we are running only one set of benchmarks that we want to measure, but for the purpose of checking if they are still compiling after a language change, it can be useful to run all of them (currently this takes a pretty long time though, but may work when going for lunch break :)).
Related to https://www.pivotaltracker.com/story/show/183369386/comments/234258671
It appears that when were doing
`from XYZ import all`
the module `XYZ` was also being taken into account during name resolution.
This was unfortunate and became problematic when one had a type with the same name defined in it.
During pattern matching one could not simply do
```
from XYZ import all
...
case ... of
_ : XYZ -> ...
```
since the compiler would complain that we try to pattern match on a type but give it a module.
The module is now excluded from the name resolution, when importing everything from the module.
It appears that this "feature" was used in a number of our tests, so they had to be adapted.
This fixes task 4 in https://www.pivotaltracker.com/story/show/183833055
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.
