Fix panic on paste from blackhole register (#4497)
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`.

Select text inserted by shell or paste (#4458)
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.

Fix panic from two windows editing the same document (#4570)
* 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

Fix `delete_char_backward` for paired characters (#4558)
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.

Closes https://github.com/helix-editor/helix/issues/4544.

Most commands that accept an argument show their current value if no

error message in the status bar if not provided with an argument:

```
Theme name not provided

It now shows the current theme name in the status bar if no argument is
specified.

GabrielDertoni 9fae4b8118 fix: terminal freezing on `shell_insert_output`
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.

Alexis (Poliorcetics) Bourget 34389e1d54 nit: Do less allocations in `ui::menu::Item::label` implementations

the functions. LSP labels especially can easily be called dozens of time in a single menu popup,
when listing references for example.

fix: write-all crash (#4384)
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.

Fix multi byte auto pairs (#4024)
* 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.

* migrate auto pairs tests to integration

* review comments

Michael Davis 66238e8556 Silence dead_code warning on AppBuilder::with_config
This function is not currently used but is likely to be useful in

Michael Davis 313579d27c Remove language-server configuration in integration tests
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.

Skyler Hawthorne d706194597 chore(write): serialize write operations within a Document
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.

Fix debug assertion for diagnostic sort order (#4319)
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.

Overlay all diagnostics with highest severity on top (#4113)
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.

Automatically track pseudo-pending text (#4077)
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`).

Michael Davis 032d76ccf2 Use Range::with_direction consistently 2 years ago
Michael Davis 274f2ea459 Use requested direction for new textobject selection range
This changes the behavior of operations like `]f`/`[f` to set the
direction of the new range to the direction of the action.

The original behavior was to always use the head of the next function.
This is inconsistent with the behavior of goto_next_paragraph and makes
it impossible to create extend variants of the textobject motions.

This causes a behavior change when there are nested functions. The
behavior in the parent commit is that repeated uses of `]f` will
select every function in the file even if nested. With this commit,
functions are skipped.

It's notable that it's possible to emulate the original behavior by
using the `ensure_selections_forward` (A-:) command between invocations
of `]f`.

Split helix_core::find_root and helix_loader::find_local_config_dirs (#3929)
* Split helix_core::find_root and helix_loader::find_local_config_dirs

The documentation of find_root described the following priority for
detecting a project root:
- Top-most folder containing a root marker in current git repository
- Git repository root if no marker detected
- Top-most folder containing a root marker if not git repository detected
- Current working directory as fallback

The commit contained in https://github.com/helix-editor/helix/pull/1249
extracted and changed the implementation of find_root in find_root_impl,
actually reversing its result order (since that is the order that made
sense for the local configuration merge, from innermost to outermost
ancestors).

Since the two uses of find_root_impl have different requirements (and
it's not a matter of reversing the order of results since, e.g., the top
repository dir should be used by find_root only if there's not marker in
other dirs), this PR splits the two implementations in two different
specialized functions.

In doing so, find_root_impl is removed and the implementation is moved
back in find_root, moving it closer to the documented behaviour thus
making it easier to verify it's actually correct

Improve keymap errors from command typos (#3931)
* Improve keymap errors from command typos

Currently, opening helix with a config containing a bad command mapping
fails with a cryptic error. For example, say we have a config (bad.toml)
with a command name that doesn't exist:

    [keys.normal]
    b = "buffer_close" # should be ":buffer-close"

When we `hx -c bad.toml`, we get...

> Bad config: data did not match any variant of untagged enum KeyTrie for key `keys.normal` at line 1 column 1
> Press <ENTER> to continue with default config

This is because of the way that Serde tries to deserialize untagged
enums such as `helix_term::keymap::KeyTrie`. From the Serde docs[^1]:

> Serde will try to match the data against each variant in order and the
> first one that deserializes successfully is the one returned.

`MappableCommand::deserialize` fails (returns an Err variant) when a
command does not exist. Serde interprets this as the `KeyTrie::Leaf`
variant failing to match and declares that the input data doesn't
"match any variant of untagged enum KeyTrie."

Luckily the variants of KeyTrie are orthogonal in structure: we can tell
them apart by the type hints from a `serde:🇩🇪:Visitor`. This change
uses a custom Deserialize implementation along with a Visitor that
discerns which variant of the KeyTrie applies. With this change, the
above failure becomes:

> Bad config: No command named 'buffer_close' for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config

We also provide more explicit information about the expectations on
the field. A config with an unexpected type produces a message with
that information and the expectation:

    [keys.normal]
    b = 1

> Bad config: invalid type: integer `1`, expected a command, list of commands, or sub-keymap for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config

Before this change:

    baz

With `extend_line_above` or `extend_line` selected the line above.

    #[|foo
    bar]#
    baz

Which is inconsistent with `extend_line_below`. This commit changes
the behavior to select the current line when it is not already
selected.

    foo
    #[|bar]#
    baz

Then further calls of `extend_line_above` extend the selection up

Share the restore_term code between panic and normal exits (#3612)
It was starting to diverge as the normal exit code was restoring the prompt but the panic code
wasn't, and the panic code was disabling bracketed paste but the normal code wasn't.

This changes the panic path slightly in that we won't disable raw mode if exiting alternate screen
and disabling bracketed paste fails. If that happens, things are so busted I don't think it matters
anyway.

Discard LSP publishDiagnostic when LS is not initialized (#3403)
This is invalid according to the [LSP spec]:

> InitializeResult, with the exception that during the initialize
> request the server is allowed to send the notifications
> window/showMessage, window/logMessage and telemetry/event as well
> as the window/showMessageRequest request to the client.

So we should discard the message when the language server is not
yet initialized. This can happen if the server sends
textDocument/publishDiagnostics before responding to the initialize
request. clojure-lsp appears to exhibit this behavior in the wild.

jumplist: Add documents to view history (#3593)
This change adds documents to the view's document history Vec.

Previously, a sequence like so would have confusing behavior:

1. Open file A: any document with an active language server
2. Find some definition that lives in another file - file B - with `gd`
3. Jump back in the jumplist with `C-o` to file A
4. Use `ga` intending to switch back to file B

The behavior prior to this change was that `ga` would switch to file
A: you could not use `ga` to switch to file B.

Derive Document language name from languages.toml name key (#3338)
* Derive Document language name from `languages.toml` `name` key

This changes switches from deriving the language name from the
`languages.toml` `scope` key to `name` (`language_id` in the
`LanguageConfiguration` type). For the most part it works to derive the
language name from scope by chopping off `source.` or `rsplit_once` on
`.` but for some languages we have now like html (`text.html.basic`),
it doesn't. This also should be a more accurate fallback for the
`language_id` method which is used in LSP and currently uses the
`rsplit_once` strategy.

Here we expose the language's name as `language_name` on `Document` and
replace ad-hoc calculations of the language name with the new method.

This is most impactful for the `file-type` statusline element which is
using `language_id`.

* Use `Document::language_name` for the `file-type` statusline element

The `file-type` indicator element in the statusline was using
`Document::language_id` which is meant to be used to for telling
Language Servers what language we're using. That works for languages
with `language-server` configurations in `languages.toml` but shows
text otherwise. The new `Document::language_name` method from the
parent commit is a more accurate way to determine the language.

Sometime recently the functionality of `m` was changed to match the

The current naming suggests that they may work generally on any
textobject, whereas their implementation really focuses on pairs.

* Change description of m textobject to match actual functionality

The current implementation of `m` no longer merely looks at the pair
character the cursor is on, but actually will search for the pair

not the entire selection.

Remove C-n and C-p from the insert mode keymap (#3340)
These are read-line-like bindings which we'd like to minimize in
insert mode in general.

In particular these two are troublesome if you have a low
`editor.idle-timeout` config and are using LSP completions: the
behavior of C-n/C-p switches from moving down/up lines to moving
down/up the completion menu, so if you hit C-n too quickly
expecting to be in the completion menu, you'll end up moving down
a line instead. Using C-p moves you back up the line but doesn't
re-trigger the completion menu. This kind of timing related change
to behavior isn't realistically that big of a deal but it can be
annoying.

Fix byte index error in signature help highlighting
The language server sends a char offset range within the

but helix uses byte offset ranges for rendering highlights. This

but the ranges were being highlighted correctly, and there were no
out of bound or indexing panics. Turns out rust-analyzer was
[incorrectly sending byte offsets] instead of char offsets and this
made it seem like all was well and good with offsets in helix during
initial testing.

Customizable/configurable status line (#2434)
* feat(statusline): add the file type (language id) to the status line

* refactor(statusline): move the statusline implementation into an own struct

* refactor(statusline): split the statusline implementation into different functions

* refactor(statusline): Append elements using a consistent API

This is a preparation for the configurability which is about to be
implemented.

* refactor(statusline): implement render_diagnostics()

This avoid cluttering the render() function and will simplify
configurability.

* feat(statusline): make the status line configurable

* refactor(statusline): make clippy happy

* refactor(statusline): avoid intermediate StatusLineObject

Use a more functional approach to obtain render functions and write to
the buffers, and avoid an intermediate StatusLineElement object.

* fix(statusline): avoid rendering the left elements twice

* refactor(statusline): make clippy happy again

* refactor(statusline): rename `buffer` into `parts`

* refactor(statusline): ensure the match is exhaustive

* fix(statusline): avoid an overflow when calculating the maximal center width

* chore(statusline): Describe the statusline configurability in the book

* chore(statusline): Correct and add documentation

* refactor(statusline): refactor some code following the code review

Avoid very small helper functions for the diagnositcs and inline them
instead.
Rename the config field `status_line` to `statusline` to remain
consistent with `bufferline`.

* chore(statusline): adjust documentation following the config field refactoring

* revert(statusline): revert regression introduced by c0a1870

* chore(statusline): slight adjustment in the configuration documentation

* feat(statusline): integrate changes from #2676 after rebasing

* refactor(statusline): remove the StatusLine struct

Because none of the functions need `Self` and all of them are in an own
file, there is no explicit need for the struct.

* fix(statusline): restore the configurability of color modes

The configuration was ignored after reintegrating the changes of #2676
in 8d28f95.

* fix(statusline): remove the spinner padding

* refactor(statusline): remove unnecessary format!()

feat(term): uniformize word-wise movement and deletion (#2500)
Ctrl-based shortcuts are common in numerous applications.

This change:
- Adds Ctrl+{Left/Right/Backspace/Delete} for word-wise movement/deletion in prompt, picker, …
- Removes Alt-Left and Alt-Right in prompt, picker, …
- Adds Alt-Delete in insert mode for forward word deletion

In some terminals, Alt-Backspace might not work because it is ambigous.
See: https://github.com/helix-editor/helix/pull/2193#issuecomment-1105042501
Hence, Alt alternative is not removed.

Reuse menu::Item trait in picker (#2814)
* Refactor menu::Item to accomodate external state

Will be useful for storing editor state when reused by pickers.

* Add some type aliases for readability

* Reuse menu::Item trait in picker

This opens the way for merging the menu and picker code in the
future, since a picker is essentially a menu + prompt. More
excitingly, this change will also allow aligning items in the
picker, which would be useful (for example) in the command palette
for aligning the descriptions to the left and the keybinds to
the right in two separate columns.

The item formatting of each picker has been kept as is, even though
there is room for improvement now that we can format the data into
columns, since that is better tackled in a separate PR.

* Rename menu::Item::EditorData to Data

* Call and inline filter_text() in sort_text() completion

Sort themes, language & files by score & then name (#2675)
* Sort themes by score & then name

Previously the themes were appearing unordered after typing ':theme '.
This sorts them first by fuzzy score and then by name so that they
generally appear in a more ordered fashion in the initial list.

The sort by name does not really pay off when there is a score so an
alternative approach would be to sort by name if there is string to
fuzzy match against and otherwise sort by score.

I've lowercased the names as that avoids lower case & upper case letters
being sorted into separate groups. There might be a preferable approach
to that though.

* Sort language & files by score then name

And change to use sort_unstable_by instead of sort_unstable_by_key as it
allows us to avoid some allocations.

I don't fully understand the flow of the 'filename_impl' function but
this seems to deliver the desired results.

Add single width left margin for completion popup (#2728)
* Add single width left margin for completion popup

* Clear with ui.menu style before rendering menu

When rendering a completion popup, the popup component will clear
the area with ui.popup and then the menu component would draw over
it using a table component. We remove the left edge of the area
before passing it to the table component (so that it will be left
as padding), and the table component uses ui.menu as the style.
If ui.menu and ui.popup are different the left edge of the popup
will look different from the rest of the popup. We avoid this by
clearing the whole area with ui.menu in Menu::render

check selection's visible width when copying on mouse click (#2711)
* check selection's visible width when copying on mouse click

Mouse-click-up copies the selection produced by dragging. The event
is ignored if the selection has a width of 1 though so you don't
copy when clicking rather than dragging. The current check copies
text when it has a visible width of 1 but is actually multiple
characters in the rope like a CRLF line-ending. With this change
we check the unicode width of the character(s) in the selection
rather than the range length, so clicking on a CRLF line-ending
does not copy.

Default rulers color to red (#2669)
* Default rulers color to red

Currently if the theme a user is using doesn't have `ui.virtual.rulers`
set and they set up a ruler it just fails silently making it really hard
to figure out what went wrong. Did they set incorrectly set the ruler?
Are they using an outdated version of Helix that doesn't support rulers?

This happened to me today, I even switched to the default theme with
the assumption that maybe my theme just doesn't have the rulers setup
properly and it still didn't work.

Not sure if this is a good idea or not, feel free to suggest better
alternatives!

Skyler Hawthorne 0f3c10a021 Fix initial selection of Document in new view
When a new View of a Document is created, a default cursor of 0, 0 is
created, and it does not get normalized to a single width cursor until
at least one movement of the cursor happens. This appears to have no
practical negative effect that I could find, but it makes tests difficult
to work with, since the initial selection is not what you expect it to be.

This changes the initial selection of a new View to be the width of the
first grapheme in the text.

* feat(theme): add separate diagnostic colors

This commit adds separate diagnostic highlight colors for the different
types of LSP severities. If the severity type doesn't exist or is
unknown, we use some fallback coloring which was in use before this
commit.

Some initial color options were also added in the theme.toml

Resolves issue #2157

* feat(theme): add docs for new diagnostic options

* feat(theme): adjust defaults & reduce redundancy

- the different colors for different diagnostic severities are now
  disabled in the default theme, instead diagnostics are just generally
  underlined (as prior to the changes of this feature)
- the theme querying is now done once instead of every iteration in the
  loop of processing every diagnostic message

Exclude cursor when doing ctrl-w (#2431)
Currently ctrl-w in insert mode deletes the cursor which results in
unexpected behavior. The patch also reduces the selection to cursor before
performing prev word to remove the behavior of removing unnecessary text
when nothing should be removed.

1. `::#(|)#::` after `ctrl-w` should be `#(|)#::`, previously `#(|)#:`
2. `#(|::)#` after `ctrl-w` should be `#(|::)#`, previously `#(|)#`

prevent selection collapse when inserting a newline (#2414)
Inserting a newline currently collapses any connected selections when inserting
or appending. It's happening because we're reducing the selections down to
their cursors (`let selection = ..` line) and then computing the new selection
based on the cursor. We're discarding the original head and anchor information
which are necessary to emulate Kakoune's behavior.

In Kakoune, inserting a newline retains the existing selection and _slides_
it (moves head and anchor by the same amount) forward by the newline and
indentation amount. Appending a newline extends the selection to include the
newline and any new indentation.

With the implementation of insert_newline here, we slide by adding the global
and local offsets to both head and anchor. We extend by adding the global
offset to both head and anchor but the local offset only to the head.

add reflow command (#2128)
* add reflow command

Users need to be able to hard-wrap text for many applications, including
comments in code, git commit messages, plaintext documentation, etc. It
often falls to the user to manually insert line breaks where appropriate
in order to hard-wrap text.

This commit introduces the "reflow" command (both in the TUI and core
library) to automatically hard-wrap selected text to a given number of
characters (defined by Unicode "extended grapheme clusters"). It handles
lines with a repeated prefix, such as comments ("//") and indentation.

* reflow: consider newlines to be word separators

* replace custom reflow impl with textwrap crate

* Sync reflow command docs with book

* reflow: add default max_line_len language setting

A-hl currently is not very consistent with hl when next object is

confusing such that some people think it should swap the keys with A-jk,
so it is better to use A-pn since that only specifies two direction.

A-jk have the same issue as in it usually moves right and is not
consistent with the behavior of jk so people may think A-hl is better,
maybe A-oi is better here since A-hl will be swapped to A-pn, A-oi can
convey the meaning of in and out, similar to some window manager keys?

feat(commands): better handling of buffer-close (#1397)
* feat(commands): better handling of buffer-close

Previously, when closing buffer, you would loose cursor position in other docs.
Also, all splits where the buffer was open would be closed.

This PR changes the behavior, if the view has also other buffer
previously viewed it switches back to the last one instead of the view
being closed. As a side effect, since the views are persisted,
 the cursor history is persisted as well.

The search implementation would start searching at the next grapheme

not be found (without wraparound) because the first grapheme is skipped.

Resolve conflicts between prompt/picker bindings (#1792)

**Ctrl + k** and **Ctrl + j**
This should kill till the end of the line on prompt, but is overridden
by the picker for scrolling. Since there are redundancies (`Ctrl + p`,
`Ctrl + n`), we can remove it from picker.

**Ctrl + f** and **Ctrl + b**
This are used by the prompt for back/forward movement. We could modify
it to be Ctrl + d and Ctrl + u, to match the `vim` behaviour.

Michael Davis b157c5a8a4 fetch and compile tree-sitter grammars in helix-term build

more quickly - both shallow and in parallel.

Michael Davis 4fc991fdec migrate grammar fetching/building code into helix-loader crate
This is a rather large refactor that moves most of the code for
loading, fetching, and building grammars into a new helix-loader
module. This works well with the [[grammars]] syntax for
languages.toml defined earlier: we only have to depend on the types
for GrammarConfiguration in helix-loader and can leave all the
[[language]] entries for helix-core.

Michael Davis 08ee949dcb add 'use-grammars' to languages.toml
The vision with 'use-grammars' is to allow the long-requested feature
of being able to declare your own set of grammars that you would like.
A simple schema with only/except grammar names controls the list
of grammars that is fetched and built. It does not (yet) control which
grammars may be loaded at runtime if they already exist.

Michael Davis 8330f6af20 add --fetch-grammars and --build-grammars CLI flags 3 years ago
Michael Davis eeb3f8e963 migrate helix-syntax crate into helix-core and helix-term
helix-syntax mostly existed for the sake of the build task which
checks and compiles the submodules. Since we won't be relying on
that process anymore, it doesn't end up making much sense to have
a very thin crate just for some functions that we could port to
helix-core.

The remaining build-related code is moved to helix-term which will
be able to provide grammar builds through the --build-grammars CLI
flag.

Fix bug with auto replacing components in compositor (#1711)
* Fix bug with auto replacing components in compositor

This was last known to be working with 5995568c at the
time of commit, but now doesn't work with latest rust
stable.

The issue probably stems from using
std::any::type_name() for finding a component in the
compositor, for which the docs explicitly warn against
considering it as a unique identifier for types.

`replace_or_push()` takes a boxed `Component` and
passes it to `find_id()` which compares this with a
bare Component. `type_name()` returns `Box<T>` for
the former and `T` for latter and we have a false
negative. This has been solved by using a generics
instead of trait objects to pass in a `T: Component`
and then use it for comparison.

I'm not exactly sure how this worked fine at the
time of commit of 5995568c; maybe the internal
implementation of `type_name()` changed to properly
indicate indirection with Box.

Show infobox to hint textobjects with `mi` and `ma` (#1686)
* Show infobox to hint textobjects with `mi` and `ma`

* Add note to infobox than any pair of characters will work too

The wording could probably be a little more clear, but I wanted to
keep it short but still accurate.

* Don't allocate a vec for the static help text

* Fix bug where `mi<esc>` would swallow next input and persist infobox

* Better help text for arbitrary pair matching in textobject selection

* Add way to add fake pending key data below status, use with `mi`/`ma`

This is a bit hacky as it makes use of global state which will end
up managed in multiple places, but has precedent in the way autoinfo
works. There should probably be a bigger refactor to handle this
kind of state better.

* Return early on anything other than `mi` and `ma` for autoinfo

* Remove "ascii" from help text with `mi` and `ma`

* Update helix-term/src/ui/editor.rs

An unwrap was unneccesarily present due to a prior contribution of mine

original pull request adding filetype filtering, but was merged before I
could address.

ignore Enter keypress when menu has no selection (#1704)
* ignore Enter keypress when menu has no selection

supersedes #1622

Builds on the work in #1285. I want to allow Enter to create a newline
when there is no selection in the autocomplete menu.

This occurs somewhat often when using LSP autocomplete in Elixir which
uses `do/end` blocks (and I set the autocomplete menu delay to 0 which
exacerbates the problem):

```elixir
defmodule MyModule do
  def do_foo(x) do
    x
  end
  def other_function(y) do|
end
```

Here the cursor is `|` in insert mode. The LSP suggests `do_foo` but I
want to create a newline. Hitting Enter currently closes the menu,
so I end up having to hit Enter twice when the module contains any
local with a `do` prefix, which can be inconsistent. With this change,
we ignore the Enter keypress to end up creating the newline in this case.

* pop compositor layer when ignoring Enter keypress

* move closing function out of consumed event result closure

* explicitly label close_fn as an 'Option<Callback>'

Configurable auto pairs (#1624)
* impl auto pairs config

Implements configuration for which pairs of tokens get auto completed.

In order to help with this, the logic for when *not* to auto complete
has been generalized from a specific hardcoded list of characters to
simply testing if the next/prev char is alphanumeric.

It is possible to configure a global list of pairs as well as at the
language level. The language config will take precedence over the
global config.

* rename AutoPair -> Pair

* clean up insert_char command

Blaž Hrastnik 11c3ba9350 Speed up ensure_next_boundary during render
This code:

    let start = ensure_grapheme_boundary_next(text, text.byte_to_char(start));
    let end = ensure_grapheme_boundary_next(text, text.byte_to_char(end));

Would convert byte to char index, but then internally immediately convert back
to byte index, operate on it, then convert it to char index.

This change reduces the amount of time spent in ensure_grapheme_boundary from
29% to 2%.

feat(commands): shrink_selection (#1340)
* feat(commands): shrink_selection

Add `shrink_selection` command that can be used to shrink
previously expanded selection.

To make `shrink_selection` work it was necessary to add
selection history to the Document since we want to shrink
the selection towards the syntax tree node that was initially
selected.

Selection history is cleared any time the user changes
selection other way than by `expand_selection`. This ensures
that we don't get some funky edge cases when user calls
`shrink_selection`.

Related: https://github.com/helix-editor/helix/discussions/1328

* Refactor shrink_selection, move history to view

* Remove useless comment

* Add default key mapping for extend&shrink selection

* Rework contains_selection method

* Shrink selection without expand selects first child
