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`.

* feat(commands): ensure_selections_forward
Add command that ensures that selections are in forward direction.
Fixes: https://github.com/helix-editor/helix/issues/1332
* Add keybinding for ensure_selections_forward
Add `A-:` keybinding for the ensure_selections_forward command.
* Re-use range.flip for flip_selections command
* feat: Update settings at runtime
fix the clippy warning

* feat(ui): file encoding in statusline
Display file encoding in statusline if the encoding
isn't UTF-8.
* Re-export encoding_rs from core
From there it can be imported by other mods
that rely on it.
* feat(lsp): configurable diagnostic severity
Allow severity of diagnostic messages to be configured.
E.g. allow turning of Hint level diagnostics.
Fixes: https://github.com/helix-editor/helix/issues/1007
* Use language_config() method
* Add documentation for diagnostic_severity
* Use unreachable for unknown severity level
* fix: documentation for diagnostic_severity config
* tmp add code for dedent
* finish normal_mode with dedent behavior
* use function pointer
* rebase from origin
* check dedent condition inside normal_mode implementation
* 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`.
