HEEx is a templating engine on top of Elixir's EEx templating
language specific to HTML that is included in Phoenix.LiveView
(though I think the plan is to eventually include it in base
Phoenix). It's a superset of EEx with some additional features
like components and slots.
The injections don't work perfectly because the Elixir grammar is
newline sensitive (the _terminator rule). See
https://github.com/elixir-lang/tree-sitter-elixir/issues/24
for more information.
* Make `:write` create nonexistent subdirectories
Prompting as to whether this should take place remains a TODO.
* Move subdirectory creation to new `w!` command
After the incremental parsing rewrite for injections (which was released
in 22.03 https://helix-editor.com/news/release-22-03-highlights/#incremental-injection-parsing-rewrite),
we can now do combined injections which lets us pull in some templating
grammars. The most notable of those is embedded-template - a pretty
straightforward grammar that covers ERB and EJS.
The grammar and highlights queries are shared between the two but they have
different injections.
* Add runtime language configuration (#1794)
* Add set-language typable command to change the language of current buffer.
* Add completer for available language options.
* Update set-language to refresh language server as well
* Add language id based config lookup on `syntax::Loader`.
* Add `Document::set_language3` to set programming language based on language
id.
* Update `Editor::refresh_language_server` to try language detection only if
language is not already set.
* Remove language detection from Editor::refresh_language_server
* Move document language detection to where the scratch buffer is saved.
* Rename Document::set_language3 to Document::set_language_by_language_id.
* Remove unnecessary clone in completers::language
It looks like a24fb17b2a (and
855e438f55) broke the typescript
highlights because typescript
; inherits: javascript
but it doesn't have those named nodes in its grammar.
So instead we can separate out JSX into its own language and copy
over everything from javascript and supplement it with the new
JSX highlights. Luckily there isn't too much duplication, just the
language configuration parts - we can re-use the parser with the
languages.toml `grammar` key and most of the queries with `inherits`.
Currently, the picker's re-using a few bindings which are also present
in the prompt. This causes some editing behaviours to not function on
the picker.
**Ctrl + k** and **Ctrl + j**
This should kill till the end of the line on prompt, but is overridden
by the picker for scrolling. Since there are redundancies (`Ctrl + p`,
`Ctrl + n`), we can remove it from picker.
**Ctrl + f** and **Ctrl + b**
This are used by the prompt for back/forward movement. We could modify
it to be Ctrl + d and Ctrl + u, to match the `vim` behaviour.

changes:
- typed fields within records which do not declare a default
value are now correctly highlighted as record fields
- the EEP49 'maybe' form is now parsed
- fixes for highlights for 'begin' and 'after' tokens
* 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
* Revert rebase slipup
* Add missing key bindings to keymap docs
* Add a note about readline bindings in insert mode
* Rewrite section on selection extend mode
We seem to have settled on this model, so no reason to say in the
docs that this is experimental. I also don't think we have any
movements that don't obey extend mode left.
* Fix table formatting
* Fix missing command for command palette binding
* Fix missed capitalization of descriptions in keymap docs
* Be consistent with multiple bindings in keymap docs
* Fix differently marked up commands in keymap docs
* Make special key capitalization consistent

* Move minor mode entry bindings to the minor modes section of keymap docs
* Add note about default register used in search commands in keymap docs
* Fix formatting of rebased addition
* Remove note about potential removal of select mode
It's been decided since to keep it

This is a rather large refactor that moves most of the code for
loading, fetching, and building grammars into a new helix-loader
module. This works well with the [[grammars]] syntax for
languages.toml defined earlier: we only have to depend on the types
for GrammarConfiguration in helix-loader and can leave all the
[[language]] entries for helix-core.
The vision with 'use-grammars' is to allow the long-requested feature
of being able to declare your own set of grammars that you would like.
A simple schema with only/except grammar names controls the list
of grammars that is fetched and built. It does not (yet) control which
grammars may be loaded at runtime if they already exist.
* Add arrow key mappings for tree-sitter parent/child/sibling nav
This helps my use case, where I use a non-qwerty layout with a
programmable mechanical keyboard, and use a layer switching key (think
fn) to send left down up right from the traditional hjkl positions.
* Add new bindings to docs
* add workflow for pushing nix flake artifacts to Cachix
* add docs on using the cachix cache from nix
* remove submodule clone from cachix workflow
* remove flake check
* Implement buffer-close-all
* Implement buffer-close-others
* Refactor all buffer close variants to use shared logic
* Fix clippy lint
* Docgen for new commands
* Shorten error message for attempting to close buffers that don't exist
* Refactor shared buffer methods to pass only editor, not whole compositor
* Switch signature of bulk buffer closing to use slice of DocumentIds
Addresses feedback that accepting an IntoIterator implementor is too
much for an internal. Also possibly saves some moving?
* 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 kotlin language
Queries taken from https://github.com/nvim-treesitter/nvim-treesitter/blob/master/queries/kotlin seem to work well enough for my needs though I don't use kotlin heavily.
* Update lang-support doc
* Updates the kotlin highlight query to use helixs scopes
* Updates the queries from PR feedback
* Adds 'shallow = true' to gitmodules
* Removes kotlin locals.scm
* Remove blank line

* Add tree-sitter-twig grammer and highlights
The gammar itself is quite basic, but is much better than nothing
for working with real files consisting mostly of html.
* Docgen for newly added grammar
After the changes to upgrade and reenable tree-sitter-haskell #1417
for the purpose of enabling Haskell syntax highlighting #1384, we
might as well take the final step.

* add tree-sitter-regex
* adapt regex highlights from upstream
* inject regex into elixir sigil_r/2 and sigil_R/2
* generate lang-support docs
* capture interesting nodes in character-ranges
* make $.character_class captures more consistent
* fix fallthrough behavior for character classes
* capture pattern characters as 'string'
* use latest tree-sitter-regex
* set elixir regex injections as combined
* add link to upstream queries
* inject regex in rust into 'Regex::new' raw string literals
* 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`.
Related: https://github.com/helix-editor/helix/discussions/1328
* Refactor shrink_selection, move history to view
* Remove useless comment
* Add default key mapping for extend&shrink selection
* Rework contains_selection method
* Shrink selection without expand selects first child
Indentation of single line statements doesn't work, i.e.
for (;;)<hit enter>
leads to
for(;;)
<cursor here>
Only blocks with curly braces are indented.
* Add injection regex for more languages
To support embedding them in other languages like markdown.
* Add llvm-mir highlighting
LLVM Machine IR is dumped as yaml files that can embed LLVM IR and
Machine IR.
To support this, add a llvm-mir-yaml language that uses the yaml
parser, but uses different injections to highlight IR and MIR.
* Update submodule with fixed multiline comments

This ensures that children nodes of $.message are included in the
injection, such as $.user or issue/pr numbers. Without this change,
diffs containing '#' or '@' characters can trip up the injection and
be parsed separately.

- Rename markup.underline.link to markup.link.url
- Add markup.link.label
- Add markup.quote
(The constructor theme scope was missing from the
docs, so unrelated to this commit).
* 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
* goto_file
* support goto_file under current cursor

* 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.
