Struct SyntaxState 

pub struct SyntaxState { /* private fields */ }

Buffer level state for parsing and highlighting visible lines.

Implementations

impl SyntaxState

pub fn try_new(lang: &str, gb: &GapBuffer, cfg: &Config) -> Result<Self, String>

pub fn prepare_insert_char(&mut self, idx: usize, ch: char, gb: &GapBuffer)

pub fn prepare_insert_string(&mut self, idx: usize, s: &str, gb: &GapBuffer)

pub fn prepare_delete_char(&mut self, idx: usize, gb: &GapBuffer)

pub fn prepare_delete_range(&mut self, from: usize, to: usize, gb: &GapBuffer)

pub fn apply_prepared_edit(&mut self, gb: &GapBuffer)

Mirror an edit that has been made to the underlying GapBuffer to the syntax state in order to keep syntax ranges in sync.

Panics

This method will panic if the edit was not previously prepared using one of the prepare_* methods.

pub fn update(&mut self, gb: &GapBuffer, from: usize, n_rows: usize)

Update internal state for the requested region to prepare for a call to Self::iter_tokenized_lines_from.

pub fn iter_tokenized_lines_from<'a>( &'a self, line: usize, gb: &'a GapBuffer, dot_range: Range, load_exec_range: Option<(bool, Range)>, ) -> LineIter<'a>

Yield per-line RangeTokens for use in a UI impl to render the contents of the associated buffer.

pub fn pretty_print_tree(&self) -> Option<String>

Return a string representation of the current syntax tree if possible

Trait Implementations

impl Debug for SyntaxState

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

Formats the value using the given formatter.
