* Optimize rendering by using Ropey::byte_sliceBlaž Hrastnik2022-03-17
| | | | | | | This avoids costly conversions via byte_to_char (which are then reversed back into bytes internally in Ropey). Reduces time spent in slice/byte_to_char from ~24% to ~5%.
* Refactor :set to parse by deserializing values (#1799)Gokul Soumya2022-03-15
| | | | | * Refactor :set to parse by deserializing values * Implement serialize for idle_timeout config
* rename '--fetch/build-grammars' flags into '--grammar fetch/build'Michael Davis2022-03-10
| | | | | The old flags were a bit long. --grammar is also aliased to -g to make it even easier.
* migrate grammar fetching/building code into helix-loader crateMichael Davis2022-03-10
| | | | | | | | | 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.
* add 'use-grammars' to languages.tomlMichael Davis2022-03-10
| | | | | | | | 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.

* replace all submodule documentation with flags documentationMichael Davis2022-03-10

* rename tree_sitter_library in LanguageConfig to 'grammar'Michael Davis2022-03-10
| | | | | | | | This is not strictly speaking necessary. tree_sitter_library was used by just one grammar: llvm-mir-yaml, which uses the yaml grammar. This will make the language more consistent, though. Each language can explicitly say that they use Some(grammar), defaulting when None to the grammar that has a grammar_id matching the language's language_id.
* migrate helix-syntax crate into helix-core and helix-termMichael Davis2022-03-10
| | | | | | | | | | | | helix-syntax mostly existed for the sake of the build task which checks and compiles the submodules. Since we won't be relying on that process anymore, it doesn't end up making much sense to have a very thin crate just for some functions that we could port to helix-core. The remaining build-related code is moved to helix-term which will be able to provide grammar builds through the --build-grammars CLI flag.
* add tree-sitter sources to languages.tomlMichael Davis2022-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | Here we add syntax to the languages.toml languge [[grammar]] name = "<name>" source = { .. } Which can be used to specify a tree-sitter grammar separately of the language that defines it, and we make this distinction for two reasons: * In later commits, we will separate this code from helix-core and bring it to a new helix-loader crate. Using separate schemas for language and grammar configurations allows for a nice divide between the types needed to be declared in helix-loader and in helix-core/syntax * Two different languages may use the same grammar. This is currently the case with llvm-mir-yaml and yaml. We could accomplish a config that works for this with just `[[languages]]`, but it gets a bit dicey with languages depending on one another. If you enable llvm-mir-yaml and disable yaml, does helix still need to fetch and build tree-sitter-yaml? It could be a matter of interpretation.

* Ensure non empty grouped nodes in textobject queriesGokul Soumya2022-03-01
|
* Allow capturing multiple nodes in textobject queriesGokul Soumya2022-03-01
| | | | | | | | | | | | | | Treesitter captures can contain multiple nodes like so: ``` (line_comment)+ @comment ``` This would match each line in a comment as a separate `@comment` capture when what we actually want is the whole set of contiguous `line_comment` nodes to be captured under the `@comment` capture. This commit enables this behaviour.

* Configurable auto pairs (#1624)Skyler Hawthorne2022-02-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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

| * fix: ensure_grapheme_boundary_next_byte needs to index at valid charBlaž Hrastnik2022-01-23
| |
| * Speed up ensure_next_boundary during renderBlaž Hrastnik2022-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | 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%.

| * fix(auto_pairs): fix auto pairs with crlf (#1470)Skyler Hawthorne2022-01-17
| | | | | | | | | | | | | | | | | | | | | | Auto pairs were resulting in incorrect ranges in the resulting when the line terminators are CRLF (i.e. Windows). It turns out this is because when we were checking if the selection was a single-width cursor, it incorrectly assumed that this would be a single char. This is not the case, as a cursor can cover a multi-code point grapheme. Therefore, we must instead explicitly work with and check graphemes to determine if the cursor should move or extend the selection. Fixes #1436

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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`.
