Problem:
vim.treesitter does not know how to map a specific filetype to a parser.
This creates problems since in a few places (including in vim.treesitter itself), the filetype is incorrectly used in place of lang.
Solution:
Add an API to enable this:
- Add vim.treesitter.language.add() as a replacement for vim.treesitter.language.require_language().
- Optional arguments are now passed via an opts table.
- Also takes a filetype (or list of filetypes) so we can keep track of what filetypes are associated with which langs.
- Deprecated vim.treesitter.language.require_language().
- Add vim.treesitter.language.get_lang() which returns the associated lang for a given filetype.
- Add vim.treesitter.language.register() to associate filetypes to a lang without loading the parser.

This allows vim.treesitter.show_tree() to work on buffers where the
filetype does not match the parser language name e.g, bash/sh.

Problem: Some injections (like markdown) allow specifying arbitrary
language names for code blocks, which may be lead to errors when
looking for a corresponding parser in runtime path.
Solution: Validate that the language name only contains alphanumeric
characters and `_` (e.g., for `c_sharp`) and error otherwise.

Extend the capabilities of is_os to detect more platforms such as
freebsd and openbsd. Also remove `iswin()` helper function as it can be
replaced by `is_os("win")`.

This is essentially a convenience wrapper around the `pending()`
function, similar to `skip_fragile()` but more general-purpose.
Also remove `pending_win32` function as it can be replaced by
`skip(iswin())`.

"pos" has a long precedent as "position" in vim, and there is no reason
to use a verbose name here.

fix(treesitter): get_captures_at_position returns metadata
Return the full `metadata` table for the capture instead of just the
priority.
Further cleanup of related docs.

The @error capture is used for tree-sitter's ERROR node, which indicates
a parsing error -- which can be quite frequent (and jarring) while typing.
Users can still manually `hi link @error Error` in their config.

Treesitter parsers are now a mandatory part of the installation and
should be tested on all platforms. Remove `pending_c_parser` helper.

This removes the support for defining links via
vim.treesitter.highlighter.hl_map (never documented, but plugins did
anyway), or the uppercase-only `@FooGroup.Bar` to `FooGroup` rule.
The fallback is now strictly `@foo.bar.lang` to `@foo.bar` to `@foo`,
and casing is irrelevant (as it already was outside of treesitter)
For compatibility, define default links to builting syntax groups
as defined by pre-existing color schemes

Problem:
1. CI logs have too many (40+) logs mentioning SIGHUP:
```
WRN 2022-06-18T16:05:47.075 T3568.22499.0/c deadly_signal:177: got signal 1 (SIGHUP)
WRN 2022-06-18T16:05:47.273 T3569.91095.0/c deadly_signal:177: got signal 1 (SIGHUP)
WRN 2022-06-18T16:05:47.651 T3570.59545.0/c deadly_signal:177: got signal 1 (SIGHUP)
```
2. TS parser test still sometimes fails on BSD CI.
3. remote_spec test fails too often.
Solution:
1. Log deadly signals at INFO level. It hasn't been helpful in CI, and
for local troubleshooting it's reasonable to adjust the loglevel as
needed.
2. Adjust the TS parser test again. ref #18911
3. Skip the remote_spec test. The `--remote` feature was merged before
it was fully formed and needs to be revisited.

The "first run" has high variability. Looks like the test failures
correlate with 545dc82c1b22709c83ec23e9450f245f9ff1babc
, which makes sense because that improves "first run" performance.
So the `1000*` factor of this test could be adjusted to e.g. `300*` or `500*`.

This allows falling back to `@definition` when we have no mapping
`@definition.fancy-specialization`.
This behavior is described in tree-sitter's documentation
(https://tree-sitter.github.io/tree-sitter/syntax-highlighting#theme).

When trying to load a language parser, escape the value of
the language.
With language injection, the language might be picked up from the
buffer. If this value is erroneous it can cause `nvim_get_runtime_file`
to hard error.
E.g., the markdown expression `~~~{` will extract '{' as a language and
then try to get the parser using `parser/{*` as the pattern.

Based on https://github.com/neovim/neovim/pull/14445
This extends `vim.treesitter.query.get_node_text` to return the text
that spans a node's range even if start_row ~= end_row.
|
| |
|
|
|
| |
Change query to include anonymous nodes (`(_)` -> `[_]`) and
use new syntax (`{vim,lua}.match?`->`#{vim,lua}.match?`)
|
| |
|
|
|
| |
Add tsnode methods to change to the next, previous, named or unnamed
nodes.

test(treesitter): skip all parsers tests if parsers aren't installed

For the case of Clojure and other Lisp syntax highlighting, it is
necessary to create huge regexps consisting of hundreds of symbols with
the pipe (|) character. To make things more difficult, these Lisp
symbols sometimes consists of special characters that are themselves
part of special regexp characters like '*'. In addition to being
difficult to maintain, it's performance is suboptimal.
This patch introduces a new predicate to perform 'source' matching in
amortized constant time. This is accomplished by compiling a hash table
on the first use.
