Treesitter captures can contain multiple nodes like so:
```
(line_comment)+ @comment
```
This would match each line in a comment as a separate
`@comment` capture when what we actually want is the
whole set of contiguous `line_comment` nodes to be
captured under the `@comment` capture. This commit enables
this behaviour.
* 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
* remove Rc
* remove some explicit cloning with another impl
* fix lint
* review comments
* global auto-pairs = false takes precedence over language settings
* make clippy happy
* print out editor config on startup
* move auto pairs accessor into Document
* rearrange auto pair doc comment
* use pattern in Froms
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%.
* add select_next_sibling and select_prev_sibling commands
* refactor objects to use higher order functions
* address clippy feedback
* move selection cloning into commands
* add default keybindings under left/right brackets
* use [+t,]+t for selecting sibling syntax nodes
* setup Alt-{j,k,h,l} default keymaps for syntax selection commands
* reduce boilerplate of select_next/prev_sibling in commands
* import tree-sitter Node type in commands
Auto pairs were resulting in incorrect ranges in the resulting when the
line terminators are CRLF (i.e. Windows). It turns out this is because
when we were checking if the selection was a single-width cursor, it
incorrectly assumed that this would be a single char. This is not the
case, as a cursor can cover a multi-code point grapheme. Therefore,
we must instead explicitly work with and check graphemes to determine
if the cursor should move or extend the selection.
Fixes#1436
* 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`.

* 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
* Add injection regex for more languages
To support embedding them in other languages like markdown.
* Add llvm-mir highlighting
LLVM Machine IR is dumped as yaml files that can embed LLVM IR and
Machine IR.
To support this, add a llvm-mir-yaml language that uses the yaml
parser, but uses different injections to highlight IR and MIR.
* Update submodule with fixed multiline comments

* feat(commands): ensure_selections_forward
Add command that ensures that selections are in forward direction.
Fixes: https://github.com/helix-editor/helix/issues/1332
* Add keybinding for ensure_selections_forward
Add `A-:` keybinding for the ensure_selections_forward command.
* Re-use range.flip for flip_selections command
* feat(ui): file encoding in statusline
Display file encoding in statusline if the encoding
isn't UTF-8.
* Re-export encoding_rs from core
From there it can be imported by other mods
that rely on it.
* feat(lsp): configurable diagnostic severity
Allow severity of diagnostic messages to be configured.
E.g. allow turning of Hint level diagnostics.
Fixes: https://github.com/helix-editor/helix/issues/1007
* Use language_config() method
* Add documentation for diagnostic_severity
* Use unreachable for unknown severity level
* fix: documentation for diagnostic_severity config
* use auto pairs with selections
Previously, the auto pairs code was converting the user selection into
its cursor form, and setting the transaction's selection to that cursor.
This has the effect of destroying the user's selection if they type a
pair character that gets auto completed.
This fixes the code to work with the user's selection, inserting auto
pairs where appropriate, but either keeping or extending the user's
selection.
* use movement::Direction instead of bool
* assume 0-width cursor is forward
