While moving completion resolve to the event system in #9668 we introduced what
is essentially a "DOS attack" on slow LSPs. Completion resolve requests were
made in the render loop and debounced with a timeout. Once the timeout expired
the resolve request was made. The problem is the next frame would immediately
request a new completion resolve request (and mark the old one as obsolete but
because LSP has no notion of cancelation the server would still process it). So
we were in essence sending one completion request to the server every 150ms and
only stopped if the server managed to respond before we rendered a new frame.
This caused overload on slower machines/with slower LS.
In this PR I revamped the resolve handler so that a request is only ever
resolved once. Both by checking if a request is already in-flight and by marking
failed resolve requests as resolved.
Make the popup positions more consistent.
Improvements:
1. if the signature popup content is bigger than the available space,
then the popup is always shown under the cursor, even if there more
space above the cursor than below
2. There is no mutation anymore inside required_size. Maybe in the future
we can update all widgets to have no mutations and change the trait

the behavior or `search` and `rsearch` match `search_next` and
`search_prev` in select mode.

Previously unnecessary/deprecated diagnostic tags replaced the highlight
for the severity of a diagnostic. This could cause either the severity
or unnecessary/deprecated scopes to disappear when diagnostic ranges
overlapped though. Plus the severity highlight can be interesting in
addition to the unnecessary/deprecated highlight.
So this change separates the unnecessary and deprecated highlights from
the severity highlights, so each is merged separately and when they
overlap, the highlights are combined.
Prior to this change, every integration test which wanted its line
endings to be handled transparently across platforms, i.e. test with
the same input that has its platform's line feed characters, converting
the line endings was up to each individual test by calling the
`platform_line` helper function. This significantly increases the amount
of boilerplate one has to copy between all the tests.
However, there are some test cases that need to exert strict control
over the exact input text without being manipulated behind the scenes by
the test framework.
So, with this change, the line feed conversions are factored into
the `TestCase` struct. By default, line endings of the input text
are converted to the platform's native line feed ending, but one can
explicitly specify in their test case when the input text should be left
alone and tested as is.
This reverts commit 0dc67ff885.
See the post-merge discussion in #9828. The old behavior was less
surprising and we have other ways to abort from a prompt, so let's
revert the behavior change.
This uses the new TreeCursor type from the parent commit to reimplement
the tree-sitter motions (`A-p/o/i/n`). Other tree-sitter related
features like textobjects are not touched with this change and will
need a different, unrelated approach to solve.
The refactor in bcf7b263 introduced a possible subtraction with overflow
when the statusline is layed out so that the left or right sides are
larger than the padding it would take to align the center area to the
middle.
When the left or right areas are too large, we can evenly space the
elements rather than trying to align the center area to the middle.
This prevents possible underflows and makes sense visually - it's
still easy to tell the areas apart at a glance.
The `shell_impl` and `shell_impl_async` functions no longer return
`success` because it was always `true`. If the command didn't succeed
both functions would return an `Err`.
This was also the reason, why `shell_keep_pipe` didn't work. It relied
upon the value of `success` and aborted in case of an `Err`.
It now removes any selection for which `shell_impl` returns `Err`.
If the command always fails, the selections are preserved and an error
message is displayed in the status bar.
In the `reload-all` command, we should not stop reloading the documents
if one error is found. Instead, we should report the error and continue
trying to reload the current open documents. This is useful in cases
where a backing file does not exist temporarily (e.g. when editing a git
patch in the outstanding chain that doesn't have a file just yet).
This change also remove the error messages in the cases where the
backing is `None`, like in new docs or `tutor`.

Steps To Reproduce

1. 2j # move_visual_line_down
1. C # copy_selection_on_next_line
1. mdm # surround_delete
Debug

`called `Result::unwrap()` on an `Err` value: Char range out of bounds:
char range 18446744073709551614..18446744073709551615,
Rope/RopeSlice char length 7', ropey-1.6.1/src/rope.rs:546:37`
Description
-----------
Processing the surrounding pairs in order violates the assertion the
ranges are ordered. To handle nested surrounds all positions have to
be sorted. Also surround_replace has to track the proper replacement
character for each position.
1. Create a document containing `{A}`
1. C-w v # vsplit
1. gl # goto_line_end
1. b # move_prev_word_start
1. ` # switch_to_lowercase
1. mrm( # surround replace
1. C-w v # vsplit
In the debug build surround_replace/delete will immedately assert with
`assertion failed: last <= from', transaction.rs:597:13`. The splits and
lowercase conversion are not needed to trigger the bug.
In the release build the surround becomes `)a(` and the last vsplit
causes the transaction to panic.
`internal error: entered unreachable code:
(Some(Retain(18446744073709551573)))', transaction.rs:185:46`
Since the selection direction is backwards get_surround_pos returns the
pairs reversed but the downstream code assumes they are in the forward
direction.
Joining lines with Alt-J does not properly select the inserted spaces
when the selection contains blank lines. In the worst case it panics
with an out of bounds index.
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value:
Char index out of bounds: char index 11, Rope/RopeSlice char length 10'

* Create a new document

e
```
* % (Select all)
* Alt-J (join and select the spaces)
URIs need to be normalized to be comparable. For example a language
server could send a URI for a path containing '+' as '%2B' but we might
encode this in something like 'Document::url' as just '+'. We can
normalize the URI straight into a PathBuf though since this is the only
value we compare these diagnostics URIs against. This also covers
edge-cases like windows drive letter capitalization.
* Use next and avoid a redundant prefix strip
* Avoid allocations
Especially when `expand_tilde` is claled on a path
that doesn't contain a tilde.
* Add a test
* Use Into<Cow<…>>
* Put the expand_tilde test at the end of the file
* Remove unused importsw

`completion/resolveItem` requests. We can now refactor this to use an
event system hook instead and lower the timeout.

`syn_loader` was replaced rather than interior value being replace,
old value was still being referenced and not updated after `:config-refresh`.
By using `ArcSwap` like for `config`, each `.load()` call will return the most

* Replace FileType::Suffix with FileType::Glob
Suffix is rather limited and cannot be used to match files which have
semantic meaning based on location + file type (for example, Github
Action workflow files). This patch adds support for a Glob FileType to
replace Suffix, which encompasses the existing behavior & adds
additional file matching functionality.
Globs are standard Unix-style path globs, which are matched against the
absolute path of the file. If the configured glob for a language is a
relative glob (that is, it isn't an absolute path or already starts with
a glob pattern), a glob pattern will be prepended to allow matching
relative paths from any directory.
The order of file type matching is also updated to first match on globs
and then on extension. This is necessary as most cases where
glob-matching is useful will have already been matched by an extension
if glob matching is done last.
* Convert file-types suffixes to globs
* Use globs for filename matching
Trying to match the file-type raw strings against both filename and
extension leads to files with the same name as the extension having the
incorrect syntax.
* Match dockerfiles with suffixes
It's common practice to add a suffix to dockerfiles based on their
context, e.g. `Dockerfile.dev`, `Dockerfile.prod`, etc.
* Make env filetype matching more generic
Match on `.env` or any `.env.*` files.
* Update docs
* Use GlobSet to match all file type globs at once
* Update todo.txt glob patterns
* Consolidate language Configuration and Loader creation
This is a refactor that improves the error handling for creating
the `helix_core::syntax::Loader` from the default and user language
configuration.
* Fix integration tests
* Add additional starlark file-type glob

Currently, helix implements operations which change the paths of files
incorrectly and inconsistently. This PR ensures that we do the following
whenever a buffer is renamed (`:move` and workspace edits)
* always send did_open/did_close notifications
* send will_rename/did_rename requests correctly
* send them to all LSP servers not just those that are active for a
buffer
* also send these requests for paths that are not yet open in a buffer (if
triggered from workspace edit).
* only send these if the server registered interests in the path
* autodetect language, indent, line ending, ..
This PR also centralizes the infrastructure for path setting and
therefore `:w <path>` benefits from similar fixed (but without didRename)
* injecting the icon through a resource file, no extra deps
* formatted
* scripted rc compilation
* formatted and restructured
* simplified conditional func call
We use `which::which` in many crates, so `which` was a separate
dependency across all of them. We can centralize `which` into the
stdx crate so it's easy for all crates to depend on it.
I also moved the rest of `helix-view/src/env.rs` into helix-stdx's
`env` module since it only contained a thin wrapper around `which`
and `std::env`.
helix-stdx is meant to carry extensions to the stdlib or low-level
dependencies that are useful in all other crates. This commit starts
with all of the path functions from helix-core and the CWD tracking that
lived in helix-loader.
The CWD tracking in helix-loader was previously unable to call the
canonicalization functions in helix-core. Switching to our custom
canonicalization code should make no noticeable difference though
since `std::env::current_dir` returns a canonicalized path with
symlinks resolved (at least on unix).
* feat(lsp): implement show document request
Implement [window.showDocument](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#window_showDocument)
LSP server-sent request.
This PR builds on top of helix-editor#5820,
moves the external-URL opening functionality into shared crate-level
function that returns a callback that is now used by both the
`open_file` command as well as the window.showDocument handler if
the URL is marked as external.

`:tree-sitter-subtree` could previously only print subtrees of nodes
in the root injection layer. We can improve on that by finding the layer
that contains the given byte range and printing the subtree within that
layer. That gives more useful results when a selection is within an
injection layer.
Make the pluralization of files and selections consistent to emphasize
the 1-to-1 relation between files and selections. The prior wording
with plural "files" and singular "selection" can mislead users into
thinking the command can open multiple files from a single selection.
Diagnostics are currently extended if text is inserted at their end. This is
desirable when inserting text after an identifier. For example consider:
let foo = 2;
--- unused variable
Renaming the identifier should extend the diagnostic:
let foobar = 2;
------ unused variable
This is currently implemented in helix but as a consequence adding whitespaces
or a type hint also extends the diagnostic:
let foo = 2;
-------- unused variable
let foo: Bar = 2;
-------- unused variable
In these cases the diagnostic should remain unchanged:
let foo = 2;
--- unused variable
let foo: Bar = 2;
--- unused variable
As a heuristic helix will now only extend diagnostics that end on a word char
if new chars are appended to the word (so not for punctuation/ whitespace).
The idea for this mapping was inspired for the word level tracking vscode uses
for many positions. While VSCode doesn't currently update diagnostics after
receiving publishDiagnostic it does use this system for inlay hints for example.
Similarly, the new association mechanism implemented here can be used for word
level tracking of inlay hints.
A similar mapping function is implemented for word starts. Together
these can be used to make a diagnostic stick to a word. If that word
is removed that diagnostic is automatically removed too. This is the exact
same behavior VSCode inlay hints eixibit.
