This fixes the modification indicator when saving from insert mode with
a config such as
[keys.insert]
C-s = ":write"
Previously the modification indicator would be stuck showing modified
even if the buffer contents matched the disk contents when writing after
some changes in insert mode with this binding. In insert mode we do not
eagerly write undo checkpoints so that all changes made become one
checkpoint as you exit insert mode. When saving, `Document`s `changes`
`ChangeSet` would be non-empty and when there are changes we show the
buffer as modified. Then switching to normal mode would append the
changes to history, bumping the current revision past what it was when
last saved. Since the last saved revision and current revision were then
unsynced, the modification indicator would always show modified.
This matches [Kakoune's behavior]. Kakoune has a different architecture
for writes but a very similar system for history, transactions and undo
checkpoints (what it calls "undo groups"). Upon saving Kakoune creates
an undo checkpoint if there are any uncommitted changes. It does this
after the write has gone through since its writing system is different.
For our writing system it's cleaner to make the undo checkpoint before
performing the save so that the history revision increments before we
send the save event.
[Kakoune's behavior]: 80fcfebca8/src/buffer.cc (L565-L566)
Previously `gf` on `~/.config/helix` for example would error if the
entire path was selected but succeed and open a picker for the directory
contents if the selection was one one-width cursor. We need to expand
tildes for all paths instead of just the auto-detected paths.
This also refactors the `goto_file` blocks a little so that we construct
`paths` once instead of creating the Vec and immediately clearing it
when the selection is one single-width cursor.
This fix allows for multiple language servers at once which support
workspace commands. This was previously broken as just the first
language server supporting workspace commands was queried when listing
allowed worspace commands.
The fix is in two parts. Firstly, querying all workspace commands from
all language servers available and using them when actually running the
command in `lsp_workspace_command`. Secondly, doing the same in
`completers::lsp_workspace_command` such that completion still works as
expected.
The fix has one remaining issue, which I am unsure how to handle in the
best way possible, but which I also don't think should happen often:
Multiple language servers may register commands with the same name. This
will lead to that command being listed in the popup menu and in the
completion list multiple times, which can be possibly confusing. One
could disambigue them in the popover menu, but I am not sure the same
can be done for completion. When running `lsp-workspace-command` with
parameters, this behavior is "fixed" by displaying an error in that
case. I am unsure if this is the best fix for this issue in that case,
but could not find a better one.
Saving while in insert mode causes issues with the modification
indicator and this is very easy to reproduce with the current state of
the auto-save hook. We can tweak the hook slightly to await the mode
switch out of insert mode to perform the save.
The debounce is preserved: if you save and then immediately exit insert
mode the debounce will be respected. If the debounce lapses while you
are in insert mode, the save occurs as you switch out of insert mode
immediately.

This is useful for resetting multiple changes at once. For example you
might use 'maf' or even '%' to select a larger region and reset all
changes within.
The original behavior of resetting the change on the current line is
retained when the primary selection is 1-width since we look for chunks
in the line range of each selection.
It can be convenient to define project specific debugger templates, some of
which might not necessitate prompting the user to define completion.
This commit makes completion optional for debugger templates and starts the
dap immediately if undefined or empty.

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

Currently the editor mode has no effect on the behavior of `search` and
`rsearch`. We can pass in the right movement for the editor mode to make
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
-----
`assertion failed: last <= from', transaction.rs:597:13`
Release
-------
`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'
Steps to reproduce:
* Create a new document
```
a
b
c
d
e
```
* % (Select all)
* Alt-J (join and select the spaces)
