* ignore Enter keypress when menu has no selection
supersedes #1622
Builds on the work in #1285. I want to allow Enter to create a newline
when there is no selection in the autocomplete menu.
This occurs somewhat often when using LSP autocomplete in Elixir which
uses `do/end` blocks (and I set the autocomplete menu delay to 0 which
exacerbates the problem):
```elixir
defmodule MyModule do
def do_foo(x) do
x
end
def other_function(y) do|
end
```
Here the cursor is `|` in insert mode. The LSP suggests `do_foo` but I
want to create a newline. Hitting Enter currently closes the menu,
so I end up having to hit Enter twice when the module contains any
local with a `do` prefix, which can be inconsistent. With this change,
we ignore the Enter keypress to end up creating the newline in this case.
* pop compositor layer when ignoring Enter keypress
* move closing function out of consumed event result closure
* explicitly label close_fn as an 'Option<Callback>'
* 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
* Add Event::Used to use event callback without consuming
* Close popup if contents ignored event
* collect event results before executing callbacks
* don't add new result variant, use Ignored(..) instead
* break in match cases
* Make auto_close configurable
* fix merge
* auto close hover popups
* fix formatting
Some users (including myself) want to turn off filtering of files
prefixed with `.`, as they are often useful to edit. For example, `.env`
files, configuration for linters `.eslint.json` and the like.
The unwrap (or '.ok()' rather) triggers for some errors but not
negative status codes. In the case where helix is being packaged
in an empty git repository, the existing mechanism will fail because
git init
git rev-parse HEAD
gives a negative exit code and prints to stderr
stderr: "fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree....
with a stdout of "HEAD\n" (too short to slice with [..8]).
* feat(commands): command palette
Add new command to display command pallete that can be used
to discover and execute available commands.
Fixes: https://github.com/helix-editor/helix/issues/559
* Make picker take the whole context, not just editor
* Bind command pallete
* Typable commands also in the palette
* Show key bindings for commands
* Fix tests, small refactor
* Refactor keymap mapping, fix typo
* Ignore sequence key bindings for now
* Apply suggestions
* Fix lint issues in tests
* Fix after rebase

In order to implement this completer, the completion function needs to
be able to access the compositor's context (to allow it to get the
list of buffers currently open in the context's editor).
If building from source and the source is contained in a larger
repository, we'd contain the wrong version. It's also easy to
accidentally have a newer tag that would change the version.
This code:
let start = ensure_grapheme_boundary_next(text, text.byte_to_char(start));
let end = ensure_grapheme_boundary_next(text, text.byte_to_char(end));
Would convert byte to char index, but then internally immediately convert back
to byte index, operate on it, then convert it to char index.
This change reduces the amount of time spent in ensure_grapheme_boundary from
29% to 2%.
* add select_next_sibling and select_prev_sibling commands
* refactor objects to use higher order functions
* address clippy feedback
* move selection cloning into commands
* add default keybindings under left/right brackets
* use [+t,]+t for selecting sibling syntax nodes
* setup Alt-{j,k,h,l} default keymaps for syntax selection commands
* reduce boilerplate of select_next/prev_sibling in commands
* import tree-sitter Node type in commands
* add show_subtree command for viewing tree-sitter subtree in Popup
* remove '.slice(..)' from show_subtree command
* name docs and subtree Popups 'hover'
* 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`.

* using if let...
* fix check
* using char_is_whitespace instead of ch.is_whitespace
* fix clippy
* abstract restore_indent function
* Add auto pairs for same-char pairs
* Add unit tests for all existing functionality
* Add auto pairs for same-char pairs (quotes, etc). Account for
apostrophe in prose by requiring both sides of the cursor to be
non-pair chars or whitespace. This also incidentally will work for
avoiding a double single quote in lifetime annotations, at least until
<> is added
* Slight factor of moving the cursor transform of the selection to
inside the hooks. This will enable doing auto pairing with selections,
and fixing the bug where auto pairs destroy the selection.
Fixes#1014
* Move `runtime/themes/base16_default_terminal.toml` to
`base16_theme.toml` alongside `theme.toml`
* Use `terminfo` crate to detect whether the terminal supports true
color and, if the user has no theme configured and their terminal does
not support true color, load the alt default theme instead of the
normal default.
Remove `terminfo` dependency, use `COLORTERM` env instead
Prevent user from switching to an unsupported theme
Add `true-color-override` option
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
Following the addition of `xtask`, `cargo run` has multiple possible
targets, necessitating the usage of `cargo run --bin hx` to run Helix
during development. This allows `cargo run` to be used to run `hx`.
1. pressing o on a line with no indentation will open a new line as
expected, but esc will then delete the line altogether
2. the kill_line behavior happens after insert mode changes are already
commited to history, and the change isn't commited. pressing u after
this will break highlighting & undo history
This reverts commit c08d2fae58.
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.

* Add constants for bracket chars
* Abort early if char under cursor is not a bracket
* Simplify bracket char validation
* Refactor node search and unify find methods

* Add command to inc/dec number under cursor
With the cursor over a number in normal mode, Ctrl + A will increment the
number and Ctrl + X will decrement the number. It works with binary, octal,
decimal, and hexidecimal numbers. Here are some examples.
0b01110100
0o1734
-24234
0x1F245
If the number isn't over a number it will try to find a number after the
cursor on the same line.
* Move several functions to helix-core
* Change to work based on word under selection
* It no longer finds the next number if the cursor isn't already over
a number.
* It only matches numbers that are part of words with other characters
like "foo123bar".
* It now works with multiple selections.
* Add some unit tests
* Fix for clippy
* Simplify some things
* Keep previous selection after incrementing
* Use short word instead of long word
This change requires us to manually handle minus sign.
* Don't pad decimal numbers if no leading zeros
* Handle numbers with `_` separators

* don't call exit_select_mode in insert mode
* avoid set_selection
* avoid duplicated current!
* 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
* Add commit hash to version info, if present
* Rename GIT_HASH to indicate that it includes version, fix linter error
* Add whitespace after use statement

Adds ctrl! and alt! macros (which existed before the big keymap
refactor) and uses them in event handling of Components. Note
that this converts crossterm's KeyEvent to our own KeyEvent on
each invocation of handle_event in Components.
Space mode and view mode are duplicated on two different
keybinds, and they tend to get out of sync by contributers
forgetting to update both of them. This commit adds a test
that explicitly checks that they are identical. Prevents
issues like #1050.
