    pub tab_size: usize,
    pub use_tabs: bool,
    pub auto_indent: bool,
    pub auto_close: bool,
    pub auto_surround: bool,
    pub whitespace: WhitespaceVisibility,
    pub formatter: Option<FormatterConfig>,

    pub highlighter: HighlighterPreference,
    pub textmate_grammar: Option<PathBuf>,
}

Resolved editor configuration for a specific buffer.

This struct contains the effective settings for a buffer after applying language-specific overrides on top of the global editor config.

Use BufferConfig::resolve() to create one from a Config and optional language ID.

Fields

tab_size: usize

Number of spaces per tab character

use_tabs: bool

Whether to insert a tab character (true) or spaces (false) when pressing Tab

auto_indent: bool

Whether to auto-indent new lines

auto_close: bool

Whether to auto-close brackets, parentheses, and quotes

auto_surround: bool

Whether to surround selected text with matching pairs

whitespace: WhitespaceVisibility

Resolved whitespace indicator visibility

formatter: Option<FormatterConfig>

Formatter command for this buffer

format_on_save: bool

Whether to format on save

on_save: Vec<OnSaveAction>

Actions to run when saving

highlighter: HighlighterPreference

Preferred highlighter backend

textmate_grammar: Option<PathBuf>

Path to custom TextMate grammar (if any)

Implementations

impl BufferConfig

pub fn resolve(global_config: &Config, language_id: Option<&str>) -> Self

Resolve the effective configuration for a buffer given its language.

This merges the global editor settings with any language-specific overrides from Config.languages.

Arguments

• global_config - The resolved global configuration
• language_id - Optional language identifier (e.g., “rust”, “python”)

pub fn indent_string(&self) -> String

Get the effective indentation string for this buffer.

Returns a tab character if use_tabs is true, otherwise returns tab_size spaces.

Trait Implementations

impl Clone for BufferConfig

fn clone(&self) -> BufferConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BufferConfig

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

Formats the value using the given formatter.
