* Split helix_core::find_root and helix_loader::find_local_config_dirs
The documentation of find_root described the following priority for
detecting a project root:
- Top-most folder containing a root marker in current git repository
- Git repository root if no marker detected
- Top-most folder containing a root marker if not git repository detected
- Current working directory as fallback
The commit contained in https://github.com/helix-editor/helix/pull/1249
extracted and changed the implementation of find_root in find_root_impl,
actually reversing its result order (since that is the order that made
sense for the local configuration merge, from innermost to outermost
ancestors).
Since the two uses of find_root_impl have different requirements (and
it's not a matter of reversing the order of results since, e.g., the top
repository dir should be used by find_root only if there's not marker in
other dirs), this PR splits the two implementations in two different
specialized functions.
In doing so, find_root_impl is removed and the implementation is moved
back in find_root, moving it closer to the documented behaviour thus
making it easier to verify it's actually correct
* helix-core: remove Option from find_root return type
It always returns some result, so Option is not needed
* Improve keymap errors from command typos
Currently, opening helix with a config containing a bad command mapping
fails with a cryptic error. For example, say we have a config (bad.toml)
with a command name that doesn't exist:
[keys.normal]
b = "buffer_close" # should be ":buffer-close"
When we `hx -c bad.toml`, we get...
> Bad config: data did not match any variant of untagged enum KeyTrie for key `keys.normal` at line 1 column 1
> Press <ENTER> to continue with default config
This is because of the way that Serde tries to deserialize untagged
enums such as `helix_term::keymap::KeyTrie`. From the Serde docs[^1]:
> Serde will try to match the data against each variant in order and the
> first one that deserializes successfully is the one returned.
`MappableCommand::deserialize` fails (returns an Err variant) when a
command does not exist. Serde interprets this as the `KeyTrie::Leaf`
variant failing to match and declares that the input data doesn't
"match any variant of untagged enum KeyTrie."
Luckily the variants of KeyTrie are orthogonal in structure: we can tell
them apart by the type hints from a `serde:🇩🇪:Visitor`. This change
uses a custom Deserialize implementation along with a Visitor that
discerns which variant of the KeyTrie applies. With this change, the
above failure becomes:
> Bad config: No command named 'buffer_close' for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config
We also provide more explicit information about the expectations on
the field. A config with an unexpected type produces a message with
that information and the expectation:
[keys.normal]
b = 1
> Bad config: invalid type: integer `1`, expected a command, list of commands, or sub-keymap for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config

* Add command line parameter to specify log file
I had the logs of my debug helix mixed in with the logs from the
production helix.
Add a `--log` command line argument to redirect any logs to other
files, making my debugging easier :-)
* Update completion files with `--log` argument
The tutor file is loaded as .txt which can potentially spawn a
language server. Then the path is unset, but the LS remains active.
This can cause panics since updates are now submitted for a doc
with no path.
As a quick workaround we remove the extension which should avoid
detection.
Fixes#3730
* Don't change config to default when refreshing invalid config
* Propely handle theme errors with config-reload
* Extract refresh theme into seperate function
Helix is first and foremost a modal editor. Willingness to support non-modal
editing is there, but it is not one that should be encouraged with the default
settings. There are an increasing number of users who are stumbling because
they are trying to use Helix as a non-modal editor, so this is an effort to
encourage new users to stop and take notice that Helix has a different paradigm
than VSCode, Sublime, etc. Users can still add these bindings back to their own
configs if they wish.
`extend_line_above` (and `extend_line` when facing backwards) skip
a line when the current range does not fully cover a line.
Before this change:
foo
b#[|a]#r
baz
With `extend_line_above` or `extend_line` selected the line above.
#[|foo
bar]#
baz
Which is inconsistent with `extend_line_below`. This commit changes
the behavior to select the current line when it is not already
selected.
foo
#[|bar]#
baz
Then further calls of `extend_line_above` extend the selection up
line-wise.
* fix: Recalculate completion when going through prompt history
* Update completion when the prompt line is changed
It should not be possible to update the line without also updating the
completion since the completion holds an index into the line.
* Fix Prompt::with_line recalculate completion
with_line was the last function where recalculate completion had to be
done manually. This function now also recalculates the completion so
that it's impossible to forget.
* Exit selection when recalculating completion
Keeping the selection index when the completion has been recalculated
doesn't make sense. This clears the selection automatically, removing
most needs to manually clear it.
* Remove &mut on save_filter

It was starting to diverge as the normal exit code was restoring the prompt but the panic code
wasn't, and the panic code was disabling bracketed paste but the normal code wasn't.
This changes the panic path slightly in that we won't disable raw mode if exiting alternate screen
and disabling bracketed paste fails. If that happens, things are so busted I don't think it matters
anyway.
Fixes a panic with a config like:
[keys.normal.space]
x = [":buffer-close"]
by bailing out of the command-execution handling if the document
doesn't exist after handling a command.
This refactor changes the overall structure of the goto_ts_object_impl
command without removing any functionality from its behavior. The
refactored motion:
* acts on all selections instead of reducing to one selection
* may be repeated with the `repeat_last_motion` (A-.) command
* informs the user when the syntax-tree is not accessible in the current buffer
This is invalid according to the [LSP spec]:

> or notifications to the client until it has responded with an

So we should discard the message when the language server is not
yet initialized. This can happen if the server sends
textDocument/publishDiagnostics before responding to the initialize
request. clojure-lsp appears to exhibit this behavior in the wild.

This change adds documents to the view's document history Vec.
(This is used by `ga` for example to access the last buffer.)
Previously, a sequence like so would have confusing behavior:
1. Open file A: any document with an active language server
2. Find some definition that lives in another file - file B - with `gd`
3. Jump back in the jumplist with `C-o` to file A
4. Use `ga` intending to switch back to file B
The behavior prior to this change was that `ga` would switch to file
A: you could not use `ga` to switch to file B.
When changing focus, the lookup with `current!` may change the
view and end up executing mode transition hooks on the newly
focused view. We should use the same view and document to execute
mode transition hooks so that switching away from a view triggers
history save points.
* Derive Document language name from `languages.toml` `name` key
This changes switches from deriving the language name from the
`languages.toml` `scope` key to `name` (`language_id` in the
`LanguageConfiguration` type). For the most part it works to derive the
language name from scope by chopping off `source.` or `rsplit_once` on
`.` but for some languages we have now like html (`text.html.basic`),
it doesn't. This also should be a more accurate fallback for the
`language_id` method which is used in LSP and currently uses the
`rsplit_once` strategy.
Here we expose the language's name as `language_name` on `Document` and
replace ad-hoc calculations of the language name with the new method.
This is most impactful for the `file-type` statusline element which is
using `language_id`.
* Use `Document::language_name` for the `file-type` statusline element
The `file-type` indicator element in the statusline was using
`Document::language_id` which is meant to be used to for telling
Language Servers what language we're using. That works for languages
with `language-server` configurations in `languages.toml` but shows
text otherwise. The new `Document::language_name` method from the
parent commit is a more accurate way to determine the language.
* let extend-line respect range direction
* fix extend above logic
* keep `x` existing binding
* Update book/src/keymap.md
