Language-specific configuration

Fields

extensions: Vec<String>

File extensions for this language (e.g., [“rs”] for Rust)

filenames: Vec<String>

Exact filenames for this language (e.g., [“Makefile”, “GNUmakefile”])

grammar: String

Tree-sitter grammar name

comment_prefix: Option<String>

Comment prefix

auto_indent: bool

Whether to auto-indent

auto_close: Option<bool>

Whether to auto-close brackets, parentheses, and quotes for this language. If not specified (null), falls back to the global editor.auto_close setting.

auto_surround: Option<bool>

Whether to auto-surround selected text with matching pairs for this language. If not specified (null), falls back to the global editor.auto_surround setting.

highlighter: HighlighterPreference

Preferred highlighter backend (auto, tree-sitter, or textmate)

textmate_grammar: Option<PathBuf>

Path to custom TextMate grammar file (optional) If specified, this grammar will be used when highlighter is “textmate”

show_whitespace_tabs: bool

Whether to show whitespace tab indicators (→) for this language Defaults to true. Set to false for languages like Go that use tabs for indentation.

use_tabs: bool

Whether pressing Tab should insert a tab character instead of spaces. Defaults to false (insert spaces based on tab_size). Set to true for languages like Go and Makefile that require tabs.

tab_size: Option<usize>

Tab size (number of spaces per tab) for this language. If not specified, falls back to the global editor.tab_size setting.

formatter: Option<FormatterConfig>

The formatter for this language (used by format_buffer command)

format_on_save: bool

Whether to automatically format on save (uses the formatter above)

on_save: Vec<OnSaveAction>

Actions to run when a file of this language is saved (linters, etc.) Actions are run in order; if any fails (non-zero exit), subsequent actions don’t run Note: Use formatter + format_on_save for formatting, not on_save

Trait Implementations

impl Clone for LanguageConfig

fn clone(&self) -> LanguageConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LanguageConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LanguageConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LanguageConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&LanguageConfig> for PartialLanguageConfig

fn from(cfg: &LanguageConfig) -> Self

Converts to this type from the input type.

impl JsonSchema for LanguageConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for LanguageConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
