Currently it is not possible to save a file with a language that
has an external formatter configuration unless the external
formatter is installed, even if the language has a Language Server
configuration capable of auto-format. This change checks that the
external formatter exists before using it to create a formatting
callback.
* 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.
Ported over from 61365dfbf3 in the `gui` branch. This will allow
adding our own events, most notably an idle timer event (useful
for adding debounced input in [dynamic pickers][1] used by interactive
global search and workspace symbols).

The command palette previously used + as a delimiter for denoting
a single key in a key sequence, (like C+w). This was at odds with
how the statusline displayed them with pending keys (like <C-w>).
This patch changes the palette formatting to the statusline formatting
* feat: make `move_vertically` aware of tabs and wide characters
* refactor: replace unnecessary checked_sub with comparison
* refactor: leave pos_at_coords unchanged and introduce separate pos_at_visual_coords
* style: include comment to explain `pos_at_visual_coords` breaking condition
* refactor: use `pos_at_visual_coords` in `text_pos_at_screen_coords`
* feat: make `copy_selection_on_line` aware of wide characters
* Display highest severity diagnostic in gutter
* Improve gutter diagnostic performance
Very slight improvement (doesn't really make a difference), iterates over the diagnostics of the line
once instead of twice.
* Add comment justifying unwrap
When a new View of a Document is created, a default cursor of 0, 0 is
created, and it does not get normalized to a single width cursor until
at least one movement of the cursor happens. This appears to have no
practical negative effect that I could find, but it makes tests difficult
to work with, since the initial selection is not what you expect it to be.
This changes the initial selection of a new View to be the width of the
first grapheme in the text.
* Use new macro syntax for encoding sequences of keys
* Make convenience helpers for common test pattern
* Use indoc for inline indented raw strings
* Add feature flag for integration testing to disable rendering
- Add file-picker.follow-symlinks configuration option (default is true), this
also controls if filename and directory completers follow symlinks.
- Update FilePicker to set editor error if opening a file fails, instead of
panicing.
Fix#1548Fix#2246
* allows passing extra formatting options to LSPs
- adds optional field 'format' to [[language]] sections in 'languages.toml'
- passes specified options the LSPs via FormattingOptions
* cleaner conversion of formatting properties
* move formatting options inside lsp::Client
* cleans up formatting properties merge
In certain circumstances it was possible to get into an infinite loop
when replaying macros such as when different macros attempt to replay
each other.
This commit adds changes to track which macros are currently being
replayed and prevent getting into infinite loops.
* Fix panic on close last buffer (#2367)
In certain circumstances it was possible to cause a panic when closing
buffers due to some mishandling of view document history.
A change has been made to delete removed documents from the history of
accessed documents for each view. The ensures we don't attempt to jump
to a deleted document by mistake.
* Move remove document code into View function 'remove_document'
* Replace 'view.jumps.remove' call with 'view.remove_document' call
This line uses the Display trait for io::ErrorKind which was
stabilized in Rust 1.60.0. We can set MSRV all the way back to
1.57.0 by replacing it with a pretty-print.
Closes#2460.
* add Tree::swap_split_in_direction()
* add swap_view_{left,down,up,right} commands, bound to H,J,K,L
respectively in the Window menu(s)
* add test for view swapping
Change the layout of existing split view from horizontal to vertical and
vica-versa. It only effects the focused view and its siblings, i.e. not
recursive.
Command is mapped to 't' or 'C-t' under the Window menus.
Inserting these with the `HashMap::insert` method evades the call
to `Selection::ensure_invariants`. The effect is that the scratch
buffer (or other buffers opened through these code-paths) can start
with a selection at (0, 0), when a file with equivalent contents ("\n")
would start with (0, 1).
I.e.:
hx
and
touch f
hx f
start with different selections even though they have an equivalent
Rope. With this change they both start with (0, 1).
* feat(commands): better handling of buffer-close
Previously, when closing buffer, you would loose cursor position in other docs.
Also, all splits where the buffer was open would be closed.
This PR changes the behavior, if the view has also other buffer
previously viewed it switches back to the last one instead of the view
being closed. As a side effect, since the views are persisted,
the cursor history is persisted as well.

* Move top level lsp config to editor.lsp
This is mainly done to accomodate the new lsp.signature-help config
option that will be introduced in https://github.com/helix-editor/helix/pull/1755
which will have to be accessed by commands. The top level config
struct is split and moved to different places, making the relocation
necessary

* Show infobox to hint textobjects with `mi` and `ma`
* Add note to infobox than any pair of characters will work too
The wording could probably be a little more clear, but I wanted to
keep it short but still accurate.
* Don't allocate a vec for the static help text
* Fix bug where `mi<esc>` would swallow next input and persist infobox
* Better help text for arbitrary pair matching in textobject selection
* Add way to add fake pending key data below status, use with `mi`/`ma`
This is a bit hacky as it makes use of global state which will end
up managed in multiple places, but has precedent in the way autoinfo
works. There should probably be a bigger refactor to handle this
kind of state better.
* Return early on anything other than `mi` and `ma` for autoinfo
* Remove "ascii" from help text with `mi` and `ma`
* Update helix-term/src/ui/editor.rs

* impl auto pairs config
Implements configuration for which pairs of tokens get auto completed.
In order to help with this, the logic for when *not* to auto complete
has been generalized from a specific hardcoded list of characters to
simply testing if the next/prev char is alphanumeric.
It is possible to configure a global list of pairs as well as at the
language level. The language config will take precedence over the
global config.
* rename AutoPair -> Pair
* clean up insert_char command
* remove Rc
* remove some explicit cloning with another impl
* fix lint
* review comments
* global auto-pairs = false takes precedence over language settings
* make clippy happy
* print out editor config on startup
* move auto pairs accessor into Document
* rearrange auto pair doc comment
* use pattern in Froms
* feat(commands): shrink_selection
Add `shrink_selection` command that can be used to shrink
previously expanded selection.
To make `shrink_selection` work it was necessary to add
selection history to the Document since we want to shrink
the selection towards the syntax tree node that was initially
selected.
Selection history is cleared any time the user changes
selection other way than by `expand_selection`. This ensures
that we don't get some funky edge cases when user calls
`shrink_selection`.

If the terminal is wrongly detected to not support true color,
`true-color-override = true` will override the detection.
Rename `true-color-override` to `true-color`
* Macros WIP
`helix_term::compositor::Callback` changed to take a `&mut Context` as
a parameter for use by `play_macro`
* Default to `@` register for macros
* Import `KeyEvent`
* Special-case shift-tab -> backtab in `KeyEvent` conversion
* Move key recording to the compositor
* Add comment
* Add persistent display of macro recording status
When macro recording is active, the pending keys display will be shifted
3 characters left, and the register being recorded to will be displayed
between brackets — e.g., `[@]` — right of the pending keys display.
* Fix/add documentation
Tree sitter returns an index referring to the position of the scope in
the scopes array. We can use that same index to avoid a hashmap lookup
and instead store the styles in an array.
This currently stores the styles in both a map and an array because the
UI still uses hashmap lookups, but it's a reasonable tradeoff.

* helix-view/view: impl method to remove document from jumps
* helix-view/editor: impl close_document
* helix-view/editor: remove close_buffer argument from `close`
According to archseer, this was never implemented or used properly. Now
that we have a proper "buffer close" function, we can get rid of this.
* helix-term/commands: implement buffer-close (bc, bclose)
This behaves the same as Kakoune's `delete-buffer` / `db` command:
* With 3 files opened by the user with `:o ab`, `:o cd`, and `:o ef`:
* `buffer-close` once closes `ef` and switches to `cd`
* `buffer-close` again closes `cd` and switches to `ab`
* `buffer-close` again closes `ab` and switches to a scratch buffer
* With 3 files opened from the command line with `hx -- ab cd ef`:
* `buffer-close` once closes `ab` and switches to `cd`
* `buffer-close` again closes `cd` and switches to `ef`
* `buffer-close` again closes `ef` and switches to a scratch buffer
* With 1 file opened (`ab`):
* `buffer-close` once closes `ab` and switches to a scratch buffer
* `buffer-close` again closes the scratch buffer and switches to a new
scratch buffer
* helix-term/commands: implement buffer-close! (bclose!, bc!)
Namely, if you have a document open in multiple splits, all the splits
will be closed at the same time, leaving only splits without that
document focused (or a scratch buffer if they were all focused on that
buffer).
* helix-view/tree: reset focus if Tree is empty
* Launch with defaults upon invalid config/theme
* Startup message if there is a problematic config
* Statusline error if trying to switch to an invalid theme
* Use serde `deny_unknown_fields` for config
