Language Servers are now configured in a separate table in `languages.toml`:
```toml
[langauge-server.mylang-lsp]
command = "mylang-lsp"
args = ["--stdio"]
config = { provideFormatter = true }
[language-server.efm-lsp-prettier]
command = "efm-langserver"
[language-server.efm-lsp-prettier.config]
documentFormatting = true
languages = { typescript = [ { formatCommand ="prettier --stdin-filepath ${INPUT}", formatStdin = true } ] }
```
The language server for a language is configured like this (`typescript-language-server` is configured by default):
```toml
[[language]]
name = "typescript"
language-servers = [ { name = "efm-lsp-prettier", only-features = [ "format" ] }, "typescript-language-server" ]
```
or equivalent:
```toml
[[language]]
name = "typescript"
language-servers = [ { name = "typescript-language-server", except-features = [ "format" ] }, "efm-lsp-prettier" ]
```
Each requested LSP feature is priorized in the order of the `language-servers` array.
For example the first `goto-definition` supported language server (in this case `typescript-language-server`) will be taken for the relevant LSP request (command `goto_definition`).
If no `except-features` or `only-features` is given all features for the language server are enabled, as long as the language server supports these. If it doesn't the next language server which supports the feature is tried.
The list of supported features are:
- `format`
- `goto-definition`
- `goto-declaration`
- `goto-type-definition`
- `goto-reference`
- `goto-implementation`
- `signature-help`
- `hover`
- `document-highlight`
- `completion`
- `code-action`
- `workspace-command`
- `document-symbols`
- `workspace-symbols`
- `diagnostics`
- `rename-symbol`
- `inlay-hints`
Another side-effect/difference that comes with this PR, is that only one language server instance is started if different languages use the same language server.
There was an issue with autocompletion of a path with a space in it.

Currently, when forward deleting (`delete_char_forward` bound to `del`,
`delete_word_forward`, `kill_to_line_end`) the cursor is moved to the
left in append mode (or generally when the cursor is at the end of the
selection). For example in a document `|abc|def` (|indicates selection)
if enter append mode the cursor is moved to `c` and the selection
becomes: `|abcd|ef`. When deleting forward (`del`) `d` is deleted. The
expectation would be that the selection doesn't shrink so that `del`
again deletes `e` and then `f`. This would look as follows:
`|abcd|ef`
`|abce|f`
`|abcf|`
`|abc |`
This is inline with how other editors like kakoune work.
However, helix currently moves the selection backwards leading to the
following behavior:
`|abcd|ef`
`|abc|ef`
`|ab|ef`
`ef`
This means that `delete_char_forward` essentially acts like
`delete_char_backward` after deleting the first character in append
mode.
To fix the problem the cursor must be moved to the right while deleting
forward (first fix in this commit). Furthermore, when the EOF char is
reached a newline char must be inserted (just like when entering
appendmode) to prevent the cursor from moving to the right
Some deletion operations (especially those that use indentation)
can generate overlapping deletion ranges when using multiple cursors.
To fix that problem a new `Transaction::delete` and
`Transaction:delete_by_selection` function were added. These functions
merge overlapping deletion ranges instead of generating an invalid
transaction. This merging of changes is only possible for deletions
and not for other changes and therefore require its own function.
The function has been used in all commands that currently delete
text by using `Transaction::change_by_selection`.
When re requesting a completion that already has a selected item we
reuse that selections savepoint. However, the selection has likely
changed since that savepoint which requires us to use the selection
from that savepoint

The current implementation didn't reload the theme if no no theme was
explicitly configured (so the default theme was used). This commit
brings `refresh_theme` in line with the initialization code.
Add new theme highlight keys, for setting the colour of the breakpoint
character and the current line at which execution has been paused at.
The two new keys are `ui.highlight.frameline` and `ui.debug.breakpoint`.
Highlight according to those keys, both the line at which debugging
is paused at and the breakpoint indicator.
Add an indicator for the current line at which execution is paused
at, themed by the `ui.debug.active` theme scope. Update various themes
to showcase how the new functionality works.
Better icons are dependent on #2869, and as such will be handled in the
future, once it lands.

While scrolling (with the `scroll`) command scrolloff was calculated
slightly differently than in `ensure_cursor_in_view` which could cause
the cursor to get stuck while scrolling
Virtual text lines (either caused by softwrapped inlay hints that take
multiple or line annotations) currently block scrolling downwards.
if the visual offset passed to char_idx_at_visual_offset or
visual_offset_from_block is within a virtual text line then the char
position before the virtual text and a visual offset are returned.
We previously ignored that visual offset and as a result the cursor
would be stuck at the start of the virtual text. This commit fixes
that by simply moving the cursor to the next char (so past the virtual
text) if this visual offset is non-zero
The current test DSL currently has no way to express being at the end of
a line, save for putting an explicit LF or CRLF inside the `#[|]#`. The
problem with this approach is that it can add unintended extra new lines
if used in conjunction with raw strings, which insert newlines for you.
This is a simple attempt to mitigate this problem. If there is an
explicit newline character at the end of the selection, and then it
is immediately followed by the same newline character at the right end
of the selection, this following newline is removed. This way, one can
express a cursor at the end of a line explicitly.
* helix-term: send the STOP signal to all processes in the process group
From kill(3p):
If pid is 0, sig shall be sent to all processes (excluding an unspecified set
of system processes) whose process group ID is equal to the process group ID

reason, there is no matching status code).

Multicursor completions may overlap and therefore overlapping
completions must be dropped to avoid crashes. Furthermore, multicursor
edits might simply be out of range if the word before/after the cursor
is shorter. This currently leads to crashes, instead these selections
are now also removed for completions.
This commit also significantly refactors snippet transaction generation
so that tabstops behave correctly with the above rules. Furthermore,
snippet tabstops need to be carefully mapped to ensure their position
is correct and consistent with our selection semantics. Finally,
we now keep a partially updated Rope while creating snippet
transactions so that we can fill information into snippets that
depends on the position in the document.
Most LSPs will complete case-insensitive matches, particularly from
lowercase to uppercase. In some cases, notably Pyright, this is given
as a simple insert text instead of TextEdit. When this happens, the
prefix text was left unedited.
* Generalised to multiple runtime directories with priorities
This is an implementation for #3346.
Previously, one of the following runtime directories were used:
1. `$HELIX_RUNTIME`
2. sibling directory to `$CARGO_MANIFEST_DIR`
3. subdirectory of user config directory
4. subdirectory of path to helix executable
The first directory provided / found to exist in this order was used as a
root for all runtime file searches (grammars, themes, queries).
This change lowers the priority of `$HELIX_RUNTIME` so that the user
config runtime has higher priority. More significantly, all of these
directories are now searched for runtime files, enabling a user to override
default or system-level runtime files. If the same file name appears
in multiple runtime directories, the following priority is now used:
1. sibling directory to `$CARGO_MANIFEST_DIR`
2. subdirectory of user config directory
3. `$HELIX_RUNTIME`
4. subdirectory of path to helix executable
One exception to this rule is that a user can have a `themes`
directory directly in the user config directory that has higher piority
to `themes` directories in runtime directories. That behaviour has been
preserved.
As part of implementing this feature `theme::Loader` was simplified
and the cycle detection logic of the theme inheritance was improved to
cover more cases and to be more explicit.
* Removed AsRef usage to avoid binary growth
* Health displaying ;-separated runtime dirs
* Changed HELIX_RUNTIME build from src instructions
* Updated doc for more detail on runtime directories
* Improved health symlink printing and theme cycle errors
The health display of runtime symlinks now prints both ends of the
link.
Separate errors are given when theme file is not found and when the
only theme file found would form an inheritence cycle.
* Satisfied clippy on passing Path
* Clarified highest priority runtime directory purpose
* Further clarified multiple runtime details in book
Also gave markdown headings to subsections.
Fixed a error with table indentation not building

Removing the len check short-circuit was the only thing needed as

Repeating completions currently crates a savepoint when a completion
popup was triggered (so after the request completed). Just like for
normal completions the savepoint must be created at the request.
The occurrence of the completion request was previously not saved in
`last_insert`. To that end a new `InsertEvent::RequestCompletion`
variant has been added. When replayed this event creates a snapshot
that is "actived" by the `TriggerCompletion` event and subsequently
used during any `InsertEvent::CompletiuonApply` events.
Completion requests are computed asynchronously to avoid common micro
freezes while editing. This means that once a completion request
completes, the state of the editor might have changed. Currently,
there is a check to ensure we are still in insert mode. However,
we also need to ensure that the view and document hasn't changed
to avoid accidentally using a savepoint with the wrong view/document.
Furthermore, the editor might request a new completion while the
previous completion request hasn't complemented yet. This can
lead to weird flickering or an outdated completion request replacing
a newer completion that has already completed (the LSP server
is not required to process completion requests in order). This change
also needed to ensure determinism/linear ordering so that completion
popup always correspond to the last completion request.
Fixing autocomplete required moving the document savepoint before the
asynchronous completion request. However, this in turn causes new bugs:
If the completion popup is open, the savepoint is restored when the
popup closes (or another entry is selected). However, at that point
a new completion request might already have been created which
would have replaced the new savepoint (therefore leading to incorrectly
applied complies).
This commit fixes that bug by allowing in arbitrary number of
savepoints to be tracked on the document. The savepoints are reference
counted and therefore remain valid as long as any reference to them
remains. Weak reference are stored on the document and any reference
that can not be upgraded anymore (hence no strong reference remain)
are automatically discarded.
Currently, the selection is not saved/restored when completion
checkpoints are applied. This is usually fine because undoing changes
usually restores maps selections back in insert mode. But this is not
always the case and especially problematic in the presence of
multi-cursor completions (since completions are applied relative to
the selection/cursor) and snippets (which can change the selection)
* LSP: Support textDocument/prepareRename
'textDocument/prepareRename' can be used by the client to ask the
server the range of the symbol under the cursor which would be changed
by a subsequent call to 'textDocument/rename' with that position.
We can use this information to fill the prompt with an accurate prefill
which can improve the UX for renaming symbols when the symbol doesn't
align with the "word" textobject. (We currently use the "word"
textobject as a default value for the prompt.)

* use max_line_width + 1 during softwrap to account for newline char
Helix softwrap implementation always wraps lines so that the newline
character doesn't get cut off so he line wraps one chars earlier then
in other editors. This is necessary, because newline chars are always
selecatble in helix and must never be hidden.
However That means that `max_line_width` currently wraps one char
earlier than expected. The typical definition of line width does not
include the newline character and other helix commands like `:reflow`
also don't count the newline character here.
This commit makes softwrap use `max_line_width + 1` instead of
`max_line_width` to correct the impedance missmatch.

When it was only used for `:reflow` it made sense to have a default

a default set to `80` would make soft-wrapping behave more aggressively.
* Allow softwrapping to ignore `text-width`
Softwrapping wraps by default to the viewport width or a configured
`text-width` (whichever's smaller). In some cases we only want to set
`text-width` to use for hard-wrapping and let longer lines flow if they
have enough space. This setting allows that.

This fixes blank row text in a DynamicPicker which is initially given
no options. This can happen for language servers which respond to
the workspace symbol request for an empty query with an empty list
of symbols, and that behavior is somewhat common since returning all
symbols as the spec suggests is very expensive.
For empty options, `Picker::new` calculated the widths of each column
as 0. We can recalculate the column widths when the new options are
set to fix this. This refactor is also a good opportunity to formalize
setting new options on a picker: besides setting the new options and
calculating column widths we also want to reset the cursor and rescore
the options.
Previously we did not respond to malformed or unhandled LSP requests.
The JSONRPC spec says that all non-notification requests must have
responses:
> When a rpc call is made, the Server MUST reply with a Response,
> except for in the case of Notifications
(Note that Helix is the "Server" in this case. Also from the spec:
"The Server is defined as the origin of Response objects and the
handler of Request objects.")
So this change sends error replies for requests which can't be parsed
or handled. Request IDs are also now added to the log messages for
unhandled requests.
This moves the `Application::claim_term` and
`helix-term::application::restore_term` functions into the helix-tui
crate. How the terminal should be claimed and restored is a TUI concern
and is implemented differently through different TUI backends.
This cleans out a lot of crossterm and TUI code in Application and
makes it easier to modify claim/restore based on information we query
from the terminal host. The child commit will take advantage of this
to cache the check for whether the host terminal supports the keyboard
enhancement protocol. Without this change, caching that information
takes much more code which is not easily reusable for anything else.
The code to restore the terminal is somewhat duplicated by this patch:
we want to restore the terminal in cases of panics. Panic handler hooks
must live for `'static` and the Application's terminal does not.
This refactors the snippet logic to be largely unaware of the rest of
the document. The completion application logic is moved into
generate_transaction_from_snippet which is extended to support
dynamically computing replacement text.
When accepting a snippet completion we automatically delete the
placeholders for now as doing so manual is quite cumbersome. In the
future we should keep these as a mark + virtual text that is
automatically removed once the cursor moves there.

This is a workaround for a freeze when suspending Helix with C-z on
non-Windows systems. The check for the keyboard enhancement protocol
locks up crossterm's internal event reading/polling system by trying to
set up multiple concurrent readers. `input_stream.next()` sets up one
reader looking for regular crossterm events while the
`supports_keyboard_enhancement` query sets up another looking for
internal events. The latter hangs for two seconds or until the former
yields an event. By handling signals first we don't lock up the mutex
by trying to read keyboard events.
Since crossterm 0.26.x, we receive press/release keyboard events on
Windows always. We can ignore the release events though to emulate
the behavior of keyboard input on Windows on crossterm 0.25.x.
When the Kitty Keyboard Protocol is enabled, S-backspace is
distinguished from backspace with no modifiers. This is awkward when
typing because it's very easy to accidentally hold shift and press
backspace temporarily when typing capital letters.
Kakoune (which is also a Kitty Keyboard Protocol application) treats
S-backspace as backspace too:

Send a `Disconnect` DAP request if the `Terminated` event is received.
According to the specification, if the debugging session was started by
as `launch`, the debuggee should be terminated alongside the session. If
instead the session was started as `attach`, it should not be disposed of.
This default behaviour can be overriden if the `supportTerminateDebuggee`
capability is supported by the adapter, through the `Disconnect` request
`terminateDebuggee` argument, as described in
[the specification][discon-spec].
This also implies saving the starting command for a debug sessions, in
order to decide which behaviour should be used, as well as validating the
capabilities of the adapter, in order to decide what the disconnect should
do.
An additional change made is handling of the `Exited` event, showing a
message if the exit code is different than `0`, for the user to be aware
off the termination failure.

The completion component has a separate branch for handling the
Escape key but it can use the `ignore_escape_key` helper added for
signature-help instead.
This should not cause a behavior change - it's just cleaning up the
completion component.
* feat(ui): deprecated completions
Mark deprecated completions using strike-through
(CROSSED_OUT modifier). The deprection information
is taken either from the `deprecated` field of the
completion item or from the completion tags.
The field seems to be the older way of passing
the deprecated information and it was already
marked as deprecated for Symbol. In completion
item the field is still valid but it seems that
the LSP is moving in the general direction of using
tags for this kind of information and as such
relying on tags as well seems reasonable and
future-proof.
So far LSP always required that `PositionEncoding.characters` is an
UTF-16 offset. Now that LSP 3.17 is available in `lsp-types` request
the server to send char offsets (UTF-32) or byte offsets (UTF-8)
instead. For compatability with old servers, UTF-16 remains as the
fallback as required by the standard.

This matches the behavior from 42ad1a9e04
but for the first and last change. The selection rules are the same
as for goto_next/prev_change: additions and modifications select the
added and modified range while deletions are represented with a point.
This will allow testing more of the code base, as well as enable UI-
specific testing.
Debug mode builds are prohibitively slow for the tests, mostly
because of the concurrency write tests. So there is now a profile for
integration tests that sets the optimization level to 2 for a few helix
crates, and lowers the number of rounds of concurrent writes to 1000.

The new version of the `toml` crate is based on `toml_edit` and does
not support zero copy deserialization anymore. So we need to deserialize
`String` instead of `&str` in the keympa
increment/decrement (C-a/C-x) had some buggy behavior where selections
could be offset incorrectly or the editor could panic with some edits
that changed the number of characters in a number or date. These stemmed
from the automatic jumping behavior which attempted to find the next
date or integer to increment. The jumping behavior also complicated the
code quite a bit and made the behavior somewhat difficult to predict
when using many cursors.
This change removes the automatic jumping behavior and only increments
or decrements when the full text in a range of a selection is a number
or date. This simplifies the code and fixes the panics and buggy
behaviors from changing the number of characters.
After changes in #5239, the loaded configuration wasn't stored,
resulting in a success message even if the instance kept the previous
configuration values.
Commit 1b89d3e535 introduced a regression
where opening a new file would no longer work, because attempting to
canonicalize its path would lead to a "No such file or directory"
error. Fall back to opening a new file when encountering an error to
fix this case.
This commit addresses issue 5193, where the author
requested that the name of the binary needed is printed along
with the rest of the health information.
This commit adds a format! macro which formats in the name of the
binary and then it will be printed along with the rest of the
debug information. The value in cmd is referenced to the call
to which, and then consumed upon the call to format!
This roughly matches the behavior of the diagnostic picker: when
jumping to a diagnostic with `[d`/`]d`/`[D`/`]D`, the range of the
diagnostic is selected instead of the start point.
A language server might send None as the response to workspace symbols.
We should treat this as the empty Vec rather than the server sending
an error status. This fixes the interaction with gopls which uses
None to mean no matching symbols.
If the new results shown by the picker select a file that hasn't been
previewed before, the idle timeout would not trigger highlighting on
that file. With this change, we reset the idle timeout and allow that
file to be highlighted on the next idle timeout event.
This change uses the idle-timeout event to trigger fetching new results
in the DynamicPicker, so idle-timeout becomes a sort of debounce. This
prevents querying the language server overly aggressively.
Most language servers limit the number of workspace symbols that
are returned with an empty query even though all symbols are
supposed to be returned, according to the spec (for perfomance
reasons). This patch adds a workspace symbol picker based on a
dynamic picker that allows re-requesting the symbols on every
keypress (i.e. when the picker query text changes). The old behavior
has been completely replaced, and I have only tested with
rust-analyzer so far.
The error messages for a theme that failed to be deserialized (or
otherwise failed to load) were covered up by the context/with_context
calls:
* The log message for a bad theme configured in config.toml would only
say "Failed to deserilaize theme"
* Selecting a bad theme via :theme would show "Theme does not exist"
With these changes, we let the TOML deserializer errors bubble up, so
the error messages can now say the line number of a duplicated
key - and that key's name - when a theme fails to load because of a
duplicated key.
Providing a theme which does not exist to :theme still gives a helpful
error message: "No such file or directory."
* Reset mode when changing buffers
This is similar to the change in
e4c9d4082a139aac3aea4506918171b96e81f5b9: reset the editor to normal
mode when changing buffers. Usually the editor is already in normal
mode but it's possible to setup insert-mode keybindings that change
buffers.
* Move normal mode entering code to Editor
This should be called internally in the Editor when changing documents
(Editor::switch) or changing focuses (Editor::focus).

Also `offset_coodrs_to_in_view` was refactored to reduce duplicated position calculations.
* Fix a wrong offset calculation in `offset_coords_to_in_view_center`
It ignored `scrolloff` if `centering` is false.
Completion edits - either basic `insert_text` strings or structured
`text_edit`s - are assumed by the LSP spec to apply to the current
cursor (or at least the trigger point). We can use the range (if any)
and text given by the Language Server to create a transaction that
changes all ranges in the current selection though, allowing auto-
complete to affect multiple cursors.
* Change default TS object bindings
Changes 'match inside/around' bindings for:
- type definition from `c` to `t`
- comments from `o` to `c`
- tests from `t` to `T`
Also changes those for the `]` / `[` bindings.

* Add a undo/redo split test case for crossing branches
* history: Switch up/down transaction chaining order
The old code tends to work in practice because, usually, either up_txns
or down_txns are empty. When both have contents though, we can run into
a panic trying to compose them all since they will disagree on the
length of the text. This fixes the panic test case in the parent
commit.

This matches the insert-mode behavior for Vim and Kakoune: if the
current line is empty except for whitespace, `<ret>` should insert a
line ending at the beginning of the line, moving any indentation to the
next line.
The 'revisions' field on History can't be treated as linear: each
Revision in the revisions Vec has a parent link and an optional child
link. We can follow those to unroll the recent history.
When using undo/redo, the history revision can be decremented. In that
case we should apply the inversions since the given revision in
History::changes_since. This prevents panics with jumplist operations
when a session uses undo/redo to move the jumplist selection outside
of the document.
This case panics since undo/redo call View::apply and here, the edit
that moves the jumplist selection out-of-bounds is not yet applied when
View::apply is called in undo/redo. View::apply should only be called
by the EditorView now.
* Add a test case for updating jumplists across windows
* Apply transactions to all views on history changes
This ensures that jumplist selections follow changes in documents, even
when there are multiple views (for example a split where both windows
edit the same document).
* Leave TODOs for cleaning up View::apply
* Use Iterator::reduce to compose history transactions

Language Servers may signal that they do not support a method in
the initialization result (server capabilities). We can check these
when making LSP requests and hint in the status line when a method
is not supported by the server. This can also prevent crashes in
servers which assume that clients do not send requests for methods
which are disabled in the server capabilities.
There is an existing pattern the LSP client module where a method
returns `Option<impl Future<Output = Result<_>>>` with `None` signaling
no support in the server. This change extends this pattern to the rest
of the client functions. And we log an error to the statusline for
manually triggered LSP calls which return `None`.
Previously, jumplists could grow unchecked. Every transaction is
applied to jumplist selections to ensure that they are up to date
and within document bounds, so this would cause every edit to become
more expensive as jumplist lengths increased throughout a session.
Setting a maximum number of entries limits the cost.
Vim and Neovim limit their jumplists:
* b298fe6cba/src/structs.h (L141)
* e8cc489acc/src/nvim/mark_defs.h (L57)
Notably, Kakoune does not. In Kakoune, changes are applied to jumplist
entries lazily as you hit `<C-o>`/`<C-i>` though, so Kakoune doesn't
have the same growing cost concerns. Kakoune also does not have a
concept of a View which limits the cost further.
Vim and Neovim limit to 100. This seems unreasonably high to me so I've
set this to 30 to start. We can increase if this is problematically
low.
d6323b7cbc changed the behavior of paste
to select the newly inserted text. This is preferrable in normal mode
because it's useful to be able to act on the new text. This behavior
is worse for insert or select mode though:
* In insert mode, the cursor ends up on the last character of the newly
selected text, so further typing inserts text before the last
character.
* In select mode, the current selection is replaced with the new text
selection which doesn't extend the current selection. With this
change, the selection is extended to include the new text.
This aligns the behavior more closely with Kakoune, but it's
coincidental instead of intentional: Kakoune doesn't implement
bracketed paste (AFAIK) which causes this behavior in insert mode,
and Kakoune doesn't have a select mode.
Previously, commands such as `r<tab>` (replace with tab) or `t<tab>`
(select till tab) had no effect. This is because `KeyCode::Tab` needs
special treatment (like `KeyCode::Enter`).
This change handles a language server exiting. This was a UX sore-spot:
if a language server crashed, Helix did not recognize the exit and
continued to send requests to it. All requests would timeout since they
would not receive responses. This would also hold-up Helix closing
itself down since it would try to gracefully shutdown the server which
is implemented in the LSP spec as a request.
We could attempt to automatically restart the language server on crash.
I left this for future work since that change will need to be slightly
complicated: it will need to cover the case of a language server
repeatedly crashing.
d7d0d5ffb7 resolves completion items on
the idle-timeout event. The `Completion::resolve_completion_item`
function blocks on the LSP request though, which blocks the compositor
and in turn blocks the event loop. So until the language server returns
the resolved completion item, Helix is unable to respond to keypresses
or other LSP messages.
This is typically ok since the resolution request is fast but for some
language servers this can be problematic, and ideally we shouldn't be
blocking like this anyways.
When receiving a `completionItem/resolve` request, the Volar server
sends a `workspace/configuration` request to Helix and blocks itself
on the response, leading to a deadlock. Eventually the resolve request
times out within Helix but Helix is locked up and unresponsive in that
window.
This change resolves the completion item without blocking the
compositor.
PR #4134 switched the autocomplete menu from alphabetical to fuzzy
sorting. This commit removes the still existing filtering by prefix and

This fixes an edge case for completing shellwords. With a file
"a b.txt" in the current directory, the sequence `:open a\<tab>`
will result in the prompt containing `:open aa\ b.txt`. This is
because the length of the input which is trimmed when replacing with
completion is calculated on the part of the input which is parsed by
shellwords and then escaped (in a separate operation), which is lossy.
In this case it loses the trailing backslash.
The fix provided here refactors shellwords to track both the _words_
(shellwords with quotes and escapes resolved) and the _parts_ (chunks
of the input which turned into each word, with separating whitespace
removed). When calculating how much of the input to delete when
replacing with the completion item, we now use the length of the last
part.
This also allows us to eliminate the duplicate work done in the
`ends_with_whitespace` check.
The text within the command palette used a custom format to display
the keybinding for a command. This change switches to the key sequence
format that we use for pending keys and macros.

* removed unnecessary cast
* improve memory allocation
* small correction
d6323b7cbc introduced a regression for
shell commands like `|`, `!`, and `<A-!>` which caused the new
selections to be incorrect. This caused a panic when piping (`|`)
would cause the new range to extend past the document end.
The paste version of this bug was fixed in
48a3965ab4.
This change also inherits the direction of the new range from the old
range and adds integration tests to ensure that the behavior isn't
broken in the future.

* removing digits lower-bound, permitting spacer
* removing max line num char limit; adding notes; qualified successors; notes

If `a\ b.txt` were a local file, `:o a\ <tab>` would fill the prompt
with `:o aa\ b.txt` because the replacement range was calculated using
the shellwords-parsed part. Escaping the part before calculating its
length fixes this edge-case.
This changes the completion items to be rendered with shellword
escaping, so a file `a b.txt` is rendered as `a\ b.txt` which matches
how it should be inputted.
8584b38cfb switched to shellwords for
completion in command-mode. This changes the conditions for choosing
whether to complete the command or use the command's completer.
This change processes the input as shellwords up-front and uses
shellword logic about whitespace to determine whether the command
or argument should be completed.
* Fix range offsets in multi-selection paste
d6323b7cbc introduced a regression with
multi-selection paste where pasting would not adjust the ranges
correctly. To fix it, we need to track the total number of characters
inserted in each changed selection and use that offset to slide each
new range forwards.
* Inherit selection directions on paste
* Add an integration-test for multi-selection pasting
The sequence "_y"_p panics because the blackhole register contains an
empty values vec. This causes a panic when pasting since it unwraps
a `slice::last`.
This follows changes in Kakoune to the same effects:
* p/<space>p: 266d1c37d0
* !/<A-!>: 85b78dda2e
Selecting the new data inserted by shell or pasting is often more
useful than retaining a selection of the pre-paste/insert content.
* Clamp highlighting range to be within document
This fixes a panic possible when two vsplits of the same document
exist and enough lines are deleted from the document so that one of
the windows focuses past the end of the document.
* Ensure cursor is in view on window change
If two windows are editing the same document, one may delete enough of
the document so that the other window is pointing at a blank page (past
the document end). In this change we ensure that the cursor is within
view whenever we switch to a new window (for example with `<C-w>w`).
* Update helix-term/src/ui/editor.rs

When backward-deleting a character, if this character and the following
character form a Pair, we want to delete both. However, there is a bug
that deletes both characters also if both characters are closers of some
Pair.
This commit fixes that by adding an additional check that the deleted
character should be an opener in a Pair.

This bug occurs on `shell_insert_output` and `shell_append_output`
commands.
The previous implementation would create a child process using the Rust
stdlib's `Command` builder. However, when nothing should be piped in
from the editor, the default value for `stdin` would be used. According
to the Rust stdlib documentation that is `Stdio::inherit` which will
make the child process inherit the parent process' stdin. This would
cause the terminal to freeze.
This change will set the child process' stdin to `Stdio::null` whenever
it doesn't pipe it. In the `if` statement where this change was made
there was an extra condition for windows that I am not sure if would
require some special treatment.
This is mostly for the sake of the diagnostics pickers: without
rendering the diagnostic styles, it's hard to tell where the entries
in the picker are pointing to.
Some language servers may not send the `documentation` field if it
is expensive to compute. Clients can request the missing field with
a completionItem/resolve request.
In this change we use the idle-timeout event to ensure that the current
completion item is resolved.
This complicates the code a little but it often divides by two the number of allocations done by
the functions. LSP labels especially can easily be called dozens of time in a single menu popup,
when listing references for example.
When we do auto formatting, the code that takes the LSP's response and applies
the changes to the document are just getting the currently focused view and
giving that to the function, basically always assuming that the document that
we're applying the change to is in focus, and not in a background view.
This is usually fine for a single view, even if it's a buffer in the
background, because it's still the same view and the selection will get updated
accordingly for when you switch back to it. But it's obviously a problem for
when there are multiple views, because if you don't have the target document in
focus, it will ask the document to update the wrong view, hence the crash.
The problem with this is picking which view to apply any selection change to.
In the absence of any more data points on the views themselves, we simply pick
the first view associated with the document we are saving.
When force quitting, we need to block on the pending writes to ensure
that write commands succeed before exiting, and also to avoid a crash
when all the views are gone before the auto format call returns from
the LS.

* Fix test::print for Unicode
The print function was not generating correct translations when
the input has Unicode (non-ASCII) in it. This is due to its use of
String::len, which gives the length in bytes, not chars.
* Fix multi-code point auto pairs
The current code for auto pairs is counting offsets by summing the
length of the open and closing chars with char::len_utf8. Unfortunately,
this gives back bytes, and the offset needs to be in chars.
Additionally, it was discovered that there was a preexisting bug where
the selection was not computed correctly in the case that the cursor
was:
1. a single grapheme in width
2. this grapheme was more than one char
3. the direction of the cursor is backwards
4. a secondary range
In this case, the offset was not being added into the anchor. This was
fixed.

This change removes language server configuration from the default
languages.toml config for integration tests. No integration-tests
currently depend on the availability of a language server but if any
future test needs to, it may provide a language server configuration
by passing an override into the `test_syntax_conf` helper.
Language-servers in integration tests cause false-positive failures
when running integration tests in GitHub Actions CI. The Windows
runner appears to have `clangd` installed and all OS runners have
the `R` binary installed but not the `R` language server package.
If a test file created by `tempfile::NamedTempFile` happens to have a
file extension of `r`, the test will most likely fail because the
R language server will fail to start and will become a broken pipe,
meaning that it will fail to shutdown within the timeout, causing a
false-positive failure. This happens surprisingly often in practice.
Language servers (especially rust-analyzer) also emit unnecessary
log output when initializing, which this change silences.
`helix_view::apply_transaction` closes over `Document::apply` and
`View::apply` to ensure that jumplist entries are updated when a
document changes from a transaction. `Document::apply` shouldn't
be called directly - this helper function should be used instead.
If a document is written with a new path, currently, in the event that
the write fails, the document still gets its path changed. This fixes
it so that the path is not updated unless the write succeeds.
The way that document writes are handled are by submitting them to the
async job pool, which are all executed opportunistically out of order. It
was discovered that this can lead to write inconsistencies when there
are multiple writes to the same file in quick succession.
This seeks to fix this problem by removing document writes from the
general pool of jobs and into its own specialized event. Now when a
user submits a write with one of the write commands, a request is simply
queued up in a new mpsc channel that each Document makes to handle its own
writes. This way, if multiple writes are submitted on the same document,
they are executed in order, while still allowing concurrent writes for
different documents.
Instead of repeatedly checking if it is in_bounds, calculate the
max_indent beforehand and just loop. I added a debug_assert to "prove"
that it never tries drawing out of bounds.
Better performance, and otherwise very long lines with lots of tabs
will wrap around the u16 and come back on the other side, messing up
the beginning skip_levels.
Also changes workspace diagnostic picker bindings to <space>D and
changes the debug menu keybind to <space>g, the previous diagnostic
picker keybind. This brings the diagnostic picker bindings more in
line with the jump to next/previous diagnostic bindings which are
currently on ]d and [d.
The debug assertion that document diagnostics are sorted incorrectly
panics for cases like `[161..164, 162..162]`. The merging behavior
in the following lines that relies on the assertion only needs the
input ranges to be sorted by `range.start`, so this change simplifies
the assertion to only catch violations of that assumption.
Undo/redo/earlier/later call `Document::apply_impl` which applies
transactions to the document. These transactions also need to be
applied to the view as in 0aedef0.
Here we separate the diagnostics by severity and then overlay the Vec
of spans for each severity on top of the highlights. The error
diagnostics end up overlaid on the warning diagnostics, which are
overlaid on the hints, overlaid on info, overlaid on any other severity
(default), then overlaid on the syntax highlights.
This fixes two things:
* Error diagnostics are now always visible when overlapped with other
diagnostics.
* Ghost text is eliminated.
* Ghost text was caused by duplicate diagnostics at the EOF:
overlaps within the merged `Vec<(usize, Range<usize>)>` violate
assumptions in `helix_core::syntax::Merge`.
* When we push a new range, we check it against the last range and
merge the two if they overlap. This is safe because they both
have the same severity and therefore highlight.
The actual merge is skipped for any of these when they are empty, so
this is very fast in practice. For some data, I threw together an FPS
counter which renders as fast as possible and logs the renders per
second.
With no diagnostics, I see an FPS gain from this change from 868 FPS
to 878 (+1.1%) on a release build on a Rust file. On an Erlang file
with 12 error diagnostics and 6 warnings in view (233 errors and 66
warnings total), I see a decrease in average FPS from 795 to 790
(-0.6%) on a release build.
It is easy to forget to call `Document::apply` and/or `View::apply` in
the correct order. This commit introduces a helper function which
closes over both calls.
This change adds View::apply calls for all Document::apply call-sites,
ensuring that changes to a document do not leave invalid entries in
the View's jumplist.

If the close method fails, the editor will quit before restoring the
terminal. This causes the shell to break if, e.g. the LS times out
shutting down.
This fixes this by always restoring the terminal after closing, and
printing out a message to stderr if there is an error.
This change automatically tracks pending text for for commands which use
on-next-key callbacks. For example, `t` will await the next key event
and "t" will be shown in the bottom right-hand corner to show that we're
in a pending state.
Previously, the text for these on-next-key commands needed to be
hard-coded into the command definition which had some drawbacks:
* It was easy to forget to write and clear the pending text.
* If a command was remapped in a custom config, the pending text would
still show the old key.
With this change, pending text is automatically tracked based on the
key events that lead to the command being executed. This works even
when the command is remapped in config and when the on-next-key
callback is nested under some key sequence (for example `mi`).

* keymap: Rename A "Insert at end of line"
The language for the `A` binding is potentially confusing because
`A` behaves like `i` done at the end of the line rather than `a`.
This change renames the command to match Kakoune's language[^1].
[^1]: 021da117cf/src/normal.cc (L2229)
* keymap: Rename I `insert_at_line_start`
* Select inserted space after join
* Split join_selections with space selection to A-J
Kakoune does that too and some users may still want to retain their selections.
* Update join_selections docs
When signature help is too large it may cause a panic when it is too
large, now I just make the hover do an intersection with surface to make
sure it never overflow.
