We clone this type very often in LSP pickers, for example diagnostics
and symbols. We can use a single Arc in many cases to avoid the
unnecessary clones.
The lsp location type has the lsp's URI type and a range. We can replace
that with a custom type private to the lsp commands module that uses the
core URI type instead.
We can't entirely replace the type with a new Location type in core.
That type might look like:
pub struct Location {
uri: crate::Uri,
range: crate::Range,
}
But we can't convert every `lsp::Location` to this type because for
definitions, references and diagnostics language servers send documents
which we haven't opened yet, so we don't have the information to convert
an `lsp::Range` (line+col) to a `helix_core::Range` (char indexing).
This cleans up the picker definitions in this file so that they can all
use helpers like `jump_to_location` and `location_to_file_location` for
the picker preview. It also removes the only use of the deprecated
`PathOrId::from_path_buf` function, allowing us to drop the owned
variant of that type in the child commit.
Whenever a document is changed helix maps various positions like the
cursor or diagnostics through the `ChangeSet` applied to the document.
Currently, this mapping handles replacements as follows:
* Move position to the left for `Assoc::Before` (start of selection)
* Move position to the right for `Assoc::After` (end of selection)
However, when text is exactly replaced this can produce weird results
where the cursor is moved when it shouldn't. For example if `foo` is
selected and a separate cursor is placed on each character (`s.<ret>`)
and the text is replaced (for example `rx`) then the cursors are moved
to the side instead of remaining in place.
This change adds a special case to the mapping code of replacements:
If the deleted and inserted text have the same (char) length then
the position is returned as if the replacement doesn't exist.
only keep selections invariant under replacement
Keeping selections unchanged if they are inside an exact replacement
is intuitive. However, for diagnostics this is not desirable as
helix would otherwise fail to remove diagnostics if replacing parts
of the document.
The `take_while` should limit the layers to those that can match the
input range so we don't always scan the entire `injection_layers`. We
can limit `depth == 1` layers to those that start before the search
`end`. Deeper layers overlap with shallower layers though so we need
to allow those layers as well in the `take_while`.
For example
```vue
<script setup lang="ts">
const foo = 'bar'.match(/foo/);
const bar = foo;
</script>
```
L2 and L3 are a typescript layer and the `/foo/` part is a small regex
layer. If you used `A-o` before the regex layer you would select the
entire typescript layer. The search in `layer_id_containing_byte_range`
would not consider the typescript layer since the regex layer comes
earlier in `injection_ranges` and that layer's start is after `end`.
The regex layer has a depth of `2` though so the change in this commit
allows scanning through that layer.

The line annotation as implemented in #5420 had two shortcomings:
* It required the height of virtual text lines to be known ahead time
* It checked for line anchors at every grapheme
The first problem made the API impractical to use in practice because
almost all virtual text needs to be softwrapped. For example inline
diagnostics should be softwrapped to avoid cutting off the diagnostic
message (as no scrolling is possible). While more complex virtual text
like side by side diffs must dynamically calculate the number of empty
lines two align two documents (which requires taking account both
softwrap and virtual text). To address this, the API has been
refactored to use a trait.
The second issue caused some performance overhead and unnecessarily
complicated the `DocumentFormatter`. It was addressed by only calling
the trait mentioned above at line breaks (instead of always). This
allows offers additional flexibility to annotations as it offers
the flexibility to align lines (needed for side by side diffs).
This introduces a custom URI type in core meant to be extended later
if we want to support other schemes. For now it's just a wrapper over a
PathBuf. We use this new URI type to firewall `lsp::Url`. This was
previously done in 8141a4a but using a custom URI type is more flexible
and will improve the way Pickers handle paths for previews in the child
commit(s).

We will use this in the child commit to improve the picker's running
indicator. Nucleo 0.4.0 includes an `active_injectors` member that we
can use to detect if anything can push to the picker. When that count
drops to zero we can remove the running indicator.
Nucleo 0.4.1 contains a fix for crashes with interactive global search
on a large directory.
When parsing injections, we skip adding a new layer if there is an
existing layer covering the same range. When doing so we did not update
the parent layer ID, so some layers could have `parent` layer IDs that
pointed to a layer that no longer existed in the `layers` HopSlotMap
which could cause a panic when using `A-o`.
To fix this we update the `parent` pointer for both newly created
injection layers and reused ones.
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.
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.
This uses the layer parentage information from the parent commit to
traverse the layers. It's a similar API to `tree_sitter:TreeCursor`
but internally it does not use a `tree_sitter::TreeCursor` currently
because that interface is behaving very unexpectedly. Using the
`next_sibling`/`prev_sibling`/`parent` API on `tree_sitter::Node`
reflects the previous code's behavior so this should result in no
surprising changes.
This commit adds a `parent` field to the `LanguageLayer`. This
information is conveniently already available when we parse injections.
This will be used in the child commit to create a type that can
traverse injection layers using this information.
Test Document
-------------
```
a)b
```
Steps to Reproduce
------------------
1. % # select_all
1. ms( # surround_add
1. mam # select_textobject_around
Debug and Release
-----------------
`thread 'main' panicked at 'Attempt to index past end of RopeSlice:
char index 7, RopeSlice char length 6', ropey-1.6.1/src/slice.rs:796:13`
Description
-----------
An index was selected beyond the end of the slice with chars_at. The fix
adds a guard check to `find_nth_open_pair`, like in the other find_nth*
functions.
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.
`syn_loader` was replaced rather than interior value being replace,
old value was still being referenced and not updated after `:config-refresh`.
By using `ArcSwap` like for `config`, each `.load()` call will return the most
updated value.

* Added required-root-patterns for situational lsp activation using globbing
* Replaced filter_map with flatten
* updated book to include required-root-patterns option
* fixed wrong function name for path
* Added globset to helix-core. Moved globset building to config parsing.
* Normalize implements AsRef
* cargo fmt
* Revert "cargo fmt"
This reverts commit ca8ce123e8.
* Replace FileType::Suffix with FileType::Glob
Suffix is rather limited and cannot be used to match files which have
semantic meaning based on location + file type (for example, Github
Action workflow files). This patch adds support for a Glob FileType to
replace Suffix, which encompasses the existing behavior & adds
additional file matching functionality.
Globs are standard Unix-style path globs, which are matched against the
absolute path of the file. If the configured glob for a language is a
relative glob (that is, it isn't an absolute path or already starts with
a glob pattern), a glob pattern will be prepended to allow matching
relative paths from any directory.
The order of file type matching is also updated to first match on globs
and then on extension. This is necessary as most cases where
glob-matching is useful will have already been matched by an extension
if glob matching is done last.
* Convert file-types suffixes to globs
* Use globs for filename matching
Trying to match the file-type raw strings against both filename and
extension leads to files with the same name as the extension having the
incorrect syntax.
* Match dockerfiles with suffixes
It's common practice to add a suffix to dockerfiles based on their
context, e.g. `Dockerfile.dev`, `Dockerfile.prod`, etc.
* Make env filetype matching more generic
Match on `.env` or any `.env.*` files.
* Update docs
* Use GlobSet to match all file type globs at once
* Update todo.txt glob patterns
* Consolidate language Configuration and Loader creation
This is a refactor that improves the error handling for creating
the `helix_core::syntax::Loader` from the default and user language
configuration.
* Fix integration tests
* Add additional starlark file-type glob

Previously we used the root syntax tree for bracket matching. We can use
the new functionality in `Syntax` for finding the correct syntax tree
for a given byte range though so we use the correct syntax tree within
injections. This improves bracket matching behavior within HTML
injections like script or style tags for example.
helix-stdx is meant to carry extensions to the stdlib or low-level
dependencies that are useful in all other crates. This commit starts
with all of the path functions from helix-core and the CWD tracking that
lived in helix-loader.
The CWD tracking in helix-loader was previously unable to call the
canonicalization functions in helix-core. Switching to our custom
canonicalization code should make no noticeable difference though
since `std::env::current_dir` returns a canonicalized path with
symlinks resolved (at least on unix).
`:tree-sitter-subtree` could previously only print subtrees of nodes
in the root injection layer. We can improve on that by finding the layer
that contains the given byte range and printing the subtree within that
layer. That gives more useful results when a selection is within an
injection layer.
Diagnostics are currently extended if text is inserted at their end. This is
desirable when inserting text after an identifier. For example consider:
let foo = 2;
--- unused variable
Renaming the identifier should extend the diagnostic:
let foobar = 2;
------ unused variable
This is currently implemented in helix but as a consequence adding whitespaces
or a type hint also extends the diagnostic:
let foo = 2;
-------- unused variable
let foo: Bar = 2;
-------- unused variable
In these cases the diagnostic should remain unchanged:
let foo = 2;
--- unused variable
let foo: Bar = 2;
--- unused variable
As a heuristic helix will now only extend diagnostics that end on a word char
if new chars are appended to the word (so not for punctuation/ whitespace).
The idea for this mapping was inspired for the word level tracking vscode uses
for many positions. While VSCode doesn't currently update diagnostics after
receiving publishDiagnostic it does use this system for inlay hints for example.
Similarly, the new association mechanism implemented here can be used for word
level tracking of inlay hints.
A similar mapping function is implemented for word starts. Together
these can be used to make a diagnostic stick to a word. If that word
is removed that diagnostic is automatically removed too. This is the exact
same behavior VSCode inlay hints eixibit.
