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.
Here we add syntax to the languages.toml languge
[[grammar]]
name = "<name>"
source = { .. }
Which can be used to specify a tree-sitter grammar separately of
the language that defines it, and we make this distinction for
two reasons:
* In later commits, we will separate this code from helix-core
and bring it to a new helix-loader crate. Using separate schemas
for language and grammar configurations allows for a nice divide
between the types needed to be declared in helix-loader and in
helix-core/syntax
* Two different languages may use the same grammar. This is currently
the case with llvm-mir-yaml and yaml. We could accomplish a config
that works for this with just `[[languages]]`, but it gets a bit
dicey with languages depending on one another. If you enable
llvm-mir-yaml and disable yaml, does helix still need to fetch and
build tree-sitter-yaml? It could be a matter of interpretation.
* Move runtime file location definitions to core
* Add basic --health command
* Add language specific --health
* Show summary for all langs with bare --health
* Use TsFeature from xtask for --health
* cargo fmt

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`.
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
* 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
