Michael Davis 1f916e65cf Create helix-stdx crate for stdlib extensions
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).

feat(lsp): implement show document request (#8865)
* feat(lsp): implement show document request

Implement [window.showDocument](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#window_showDocument)
LSP server-sent request.

This PR builds on top of helix-editor#5820,
moves the external-URL opening functionality into shared crate-level
function that returns a callback that is now used by both the
`open_file` command as well as the window.showDocument handler if
the URL is marked as external.

* add return

* use vertical split

* refactor

Initialize diagnostics when opening a document (#8873) 5 months ago
Pascal Kuthe 783ff27b1b consistent diagnostic sorting 6 months ago
Pascal Kuthe 515ef17207 make diagnostics stick to word boundaries
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.

LSP: Discard publishDiagnostic from uninitialized servers (#7467)
The spec explicitly disallows publishDiagnostic to be sent before
the initialize response:

> ... the server is not allowed to send any requests or notifications to
> the client until it has responded with an InitializeResult ...

(https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize)

But if a non-compliant server sends this we currently panic because we
'.expect()' the server capabilities to be known to fetch the position
encoding. Instead of panicking we can discard the notification and log
the non-compliant behavior.

Philipp Mildenberger 7d4f7eb4bd Fix 'WorkspaceConfiguration' request with empty configuration section strings 1 year ago
Philipp Mildenberger 71551d395b Adds support for multiple language servers per language.
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.

helix-term: send the STOP signal to all processes in the process group (#3546)
* helix-term: send the STOP signal to all processes in the process group

From kill(3p):

    If pid is 0, sig shall be sent to all processes (excluding an unspecified set
    of  system processes) whose process group ID is equal to the process group ID
    of the sender, and for which the process has permission to send a signal.

This fixes the issue of running `git commit`, attempting to suspend
helix with ^Z, and then not regaining control over the terminal and
having to press ^Z again.

* helix-term: use libc directly to send STOP signal

* helix-term: document safety of libc::kill

* helix-term: properly handle libc::kill's failure

I misread the manpage for POSIX `kill` -- it returns `-1` in
the failure case, and sets `errno`, which is retrieved via
`std::io::Error::last_os_error()`, has its string representation printed
out, and then exits with the matching status code (or 1 if, for whatever
reason, there is no matching status code).

* helix-term: expand upon why we need to SIGSTOP the entire process group

Also add a link back to one of the upstream issues.

Generalised to multiple runtime directories with priorities (#5411)
* Generalised to multiple runtime directories with priorities

This is an implementation for #3346.

Previously, one of the following runtime directories were used:

1. `$HELIX_RUNTIME`
2. sibling directory to `$CARGO_MANIFEST_DIR`
3. subdirectory of user config directory
4. subdirectory of path to helix executable

The first directory provided / found to exist in this order was used as a
root for all runtime file searches (grammars, themes, queries).

This change lowers the priority of `$HELIX_RUNTIME` so that the user
config runtime has higher priority. More significantly, all of these
directories are now searched for runtime files, enabling a user to override
default or system-level runtime files. If the same file name appears
in multiple runtime directories, the following priority is now used:

1. sibling directory to `$CARGO_MANIFEST_DIR`
2. subdirectory of user config directory
3. `$HELIX_RUNTIME`
4. subdirectory of path to helix executable

One exception to this rule is that a user can have a `themes`
directory directly in the user config directory that has higher piority
to `themes` directories in runtime directories. That behaviour has been
preserved.

As part of implementing this feature `theme::Loader` was simplified
and the cycle detection logic of the theme inheritance was improved to
cover more cases and to be more explicit.

* Removed AsRef usage to avoid binary growth

* Health displaying ;-separated runtime dirs

* Changed HELIX_RUNTIME build from src instructions

* Updated doc for more detail on runtime directories

* Improved health symlink printing and theme cycle errors

The health display of runtime symlinks now prints both ends of the
link.

Separate errors are given when theme file is not found and when the
only theme file found would form an inheritence cycle.

* Satisfied clippy on passing Path

* Clarified highest priority runtime directory purpose

* Further clarified multiple runtime details in book

Also gave markdown headings to subsections.

Fixed a error with table indentation not building
table that also appears present on master.

LSP: Send replies for malformed and unhandled RPC requests (#6058)
Previously we did not respond to malformed or unhandled LSP requests.
The JSONRPC spec says that all non-notification requests must have
responses:

> When a rpc call is made, the Server MUST reply with a Response,
> except for in the case of Notifications

(Note that Helix is the "Server" in this case. Also from the spec:
"The Server is defined as the origin of Response objects and the
handler of Request objects.")

So this change sends error replies for requests which can't be parsed
or handled. Request IDs are also now added to the log messages for
unhandled requests.

Michael Davis 3d85024717 Move terminal claim/restore code to helix-tui
This moves the `Application::claim_term` and
`helix-term::application::restore_term` functions into the helix-tui
crate. How the terminal should be claimed and restored is a TUI concern
and is implemented differently through different TUI backends.

This cleans out a lot of crossterm and TUI code in Application and
makes it easier to modify claim/restore based on information we query
from the terminal host. The child commit will take advantage of this
to cache the check for whether the host terminal supports the keyboard
enhancement protocol. Without this change, caching that information
takes much more code which is not easily reusable for anything else.

The code to restore the terminal is somewhat duplicated by this patch:
we want to restore the terminal in cases of panics. Panic handler hooks
must live for `'static` and the Application's terminal does not.

fix: Handle signals before crossterm events (#6170)
This is a workaround for a freeze when suspending Helix with C-z on
non-Windows systems. The check for the keyboard enhancement protocol
locks up crossterm's internal event reading/polling system by trying to
set up multiple concurrent readers. `input_stream.next()` sets up one
reader looking for regular crossterm events while the
`supports_keyboard_enhancement` query sets up another looking for
internal events. The latter hangs for two seconds or until the former
yields an event. By handling signals first we don't lock up the mutex
by trying to read keyboard events.
