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%.

* 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`.

* 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
* Remove bracket constants
* 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 affect register and history in insert mode
* add insert_register

* 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.
b which was assigned to page_up conflicts with
align to bottom, so this commit replaces page up,
down, etc keybinds to use normal mode keybinds
(C-f, C-b, etc) in view mode too.
