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).
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.
* rust-toolchain.toml: bump MSRV to 1.70.0

The aim is to make it slow enough it only triggers during a typing
pause, but not too slow. Initial value was chosen as a safe slow
default but I've been using 250 for a while.

* commit updated documentation changes
* changes scope method to return &str so that callers can decide whether or not to own
Use `default` instead of `reset`, as this is the conventional name for ANSI codes 39/49. The word `reset` should be reserved for ANSI code `0`, which resets both fg and bg colors at once, while also removing all modifiers. While the code uses the value name `Reset`, this is misleading and should not leak into the user space.
* transition to nucleo for fuzzy matching
* drop flakey test case
since the picker streams in results now any test that relies
on the picker containing results is potentially flakely
* use crates.io version of nucleo
* Fix typo in commands.rs

Since the clipboard provider now lives on the Registers type, we want
to eliminate it from the Editor. We can do that and clean up the
commands that interact with the clipboard by calling regular yank,
paste and replace impls on the clipboard special registers.
Eventually the clipboard commands could be removed once macro keybinding
is supported.
This fixes a discrepancy between regular registers which are used for
yanking multiple values (for example via `"ay`) and regular registers
that store a history of values (for example `"a*`).
Previously, the preview shown in `select_register`'s infobox would show
the oldest value in history. It's intuitive and useful to see the most
recent value pushed to the history though.
We cannot simply switch the preview line from `values.first()`
to `values.last()`: that would fix the preview for registers
used for history but break the preview for registers used to yank
multiple values. We could push to the beginning of the values with
`Registers::push` but this is wasteful from a performance perspective.
Instead we can have `Registers::read` return an iterator that
returns elements in the reverse order and reverse the values in
`Register::write`. This effectively means that `push` adds elements to
the beginning of the register's values. For the sake of the preview, we
can switch to `values.last()` and that is then correct for both usage-
styles. This also needs a change to call-sites that read the latest
history value to switch from `last` to `first`.
This is an unfortunately noisy change: we need to update virtually all
callsites that access the registers. For reads this means passing in the
Editor and for writes this means handling potential failure when we
can't write to a clipboard register.
These special registers join and copy the values to the clipboards with
'*' corresponding to the system clipboard and '+' to the primary as
they are in Vim. This also uses the trick from PR6889 to save the values
in the register and re-use them without joining into one value when
pasting a value which was yanked and not changed.
These registers are not implemented in Kakoune but Kakoune also does
not have a built-in clipboard integration.

This register also comes from Kakoune. It's read-only and produces the
current document's name, defaulting to the scratch buffer name
constant.
(Also see PR5577.)

These come from Kakoune:
* '#' is the selection index register. It's read-only and produces the
selection index numbers, 1-indexed.
* '.' is the selection contents register. It is also read-only and
mirrors the contents of the current selections when read.
We switch the iterators returned from Selection's `fragments` and
`slices` methods to ExactSizeIterators because:
* The selection contents register can simply return the fragments
iterator.
* ExactSizeIterator is already implemented for iterators over Vecs, so
it's essentially free.
* The `len` method can be useful on its own.
This sets up a new Registers type that will allow us to expand support
for special registers. (See the child commits.)
We start simple with the regular (`Vec<String>`) registers and the
simplest special register, the black hole. In the child commits we
will expand these match arms with more special registers.
The upcoming special registers will need a few things that aren't
possible with the current Registers type in helix-core:
* Access to the `Editor`. This is only necessary when reading from
registers, so the `&Editor` parameter is only added to
`Registers::read`.
* Returning owned values. Registers in helix-core returns references
to the values backed by the `Vec<String>` but future special registers
will need to return owned values. We refactor the return value of the
read operations to give `Cow<str>`s and iterators over those.
* Returning a `Result` for write/push functions. This will be used by
the clipboard special registers.
Pascal and I discussed this and we think it's generally better to
take a 'RopeSlice' rather than a '&Rope'. The code block rendering
function in the markdown component module is a good example for how
this can be useful: we can remove an allocation of a rope and instead
directly turn a '&str' into a 'RopeSlice' which is very cheap.
A change to prefer 'RopeSlice' to '&Rope' whenever the rope isn't
modified would be nice, but it would be a very large diff (around 500+
500-). Starting off with just the syntax functions seems like a nice
middle-ground, and we can remove a Rope allocation because of it.

* Add initial support for LSP DidChangeWatchedFiles
* Move file event Handler to helix-lsp
* Simplify file event handling
* Refactor file event handling
* Block on future within LSP file event handler
* Fully qualify uses of the file_event::Handler type
* Rename ops field to options
* Revert newline removal from helix-view/Cargo.toml
* Ensure file event Handler is cleaned up when lsp client is shutdown
* _apply_motion generalization where possible
API encourages users to not forget setting `editor.last_motion` when
applying a motion. But also not setting `last_motion` without applying a
motion first.
* (rename) will_find_char -> find_char
method name makes it sound like it would be returning a boolean.
* use _apply_motion in find_char
Feature that falls out from this is that repetitions of t,T,f,F are
saved with the context extention/move and count. (Not defaulting to extend
by 1 count).
* Finalize apply_motion API
last_motion is now a private field and can only be set by calling
Editor.apply_motion(). Removing need (and possibility) of writing:
`motion(editor); editor.last_motion = motion`
Now it's just: `editor.apply_motion(motion)`
* editor.last_message: rm Box wrap around Arc
* Use pre-existing `Direction` rather than custom `SearchDirection`.
* `LastMotion` type alias for `Option<Arc<dyn Fn(&mut Editor)>>`
* Take motion rather than cloning it.

This resolves some confusing behavior where a scratch document created
by piping into hx is discarded when navigating away from that document.
We discard any scratch documents that are not modified and the original
`Editor::new_file_from_stdin` would create unmodified documents. We
refactor this function to create an empty document first and then to
apply the text from stdin as a change.
Does not change any behavior other than making the tuple slightly
more idiomatic. Keymap infobox shows key events, then the respective
description. This commit makes sure that order is used from the get go,
rather than flipping it midway.
* Add `helix_lsp::client::Client::supports_feature(&self, LanguageServerFeature)`
* Extend `doc.language_servers_with_feature` to use this method as filter as well
* Add macro `language_server_with_feature!` to reduce boilerplate for non-mergeable language server requests (like goto-definition)
* Refactored most of the `find_map` code to use the either the macro or filter directly via `doc.language_servers_with_feature`
Language Servers are now configured in a separate table in `languages.toml`:
```toml
[langauge-server.mylang-lsp]
command = "mylang-lsp"
args = ["--stdio"]
config = { provideFormatter = true }
[language-server.efm-lsp-prettier]
command = "efm-langserver"
[language-server.efm-lsp-prettier.config]
documentFormatting = true
languages = { typescript = [ { formatCommand ="prettier --stdin-filepath ${INPUT}", formatStdin = true } ] }
```
The language server for a language is configured like this (`typescript-language-server` is configured by default):
```toml
[[language]]
name = "typescript"
language-servers = [ { name = "efm-lsp-prettier", only-features = [ "format" ] }, "typescript-language-server" ]
```
or equivalent:
```toml
[[language]]
name = "typescript"
language-servers = [ { name = "typescript-language-server", except-features = [ "format" ] }, "efm-lsp-prettier" ]
```
Each requested LSP feature is priorized in the order of the `language-servers` array.
For example the first `goto-definition` supported language server (in this case `typescript-language-server`) will be taken for the relevant LSP request (command `goto_definition`).
If no `except-features` or `only-features` is given all features for the language server are enabled, as long as the language server supports these. If it doesn't the next language server which supports the feature is tried.
The list of supported features are:
- `format`
- `goto-definition`
- `goto-declaration`
- `goto-type-definition`
- `goto-reference`
- `goto-implementation`
- `signature-help`
- `hover`
- `document-highlight`
- `completion`
- `code-action`
- `workspace-command`
- `document-symbols`
- `workspace-symbols`
- `diagnostics`
- `rename-symbol`
- `inlay-hints`
Another side-effect/difference that comes with this PR, is that only one language server instance is started if different languages use the same language server.
When re requesting a completion that already has a selected item we
reuse that selections savepoint. However, the selection has likely
changed since that savepoint which requires us to use the selection
from that savepoint
