}

Syntax highlighter with ANSI color. Rustyline will try to handle escape sequence for ANSI color on windows when not supported natively (windows <10).

Currently, the highlighted version must have the same display width as the original input.

Provided methods

fn highlight<'l>(&self, line: &'l str, pos: usize) -> Cow<'l, str>[src]

Takes the currently edited line with the cursor position and returns the highlighted version (with ANSI color).

For example, you can implement blink-matching-paren.

fn highlight_prompt<'b, 's: 'b, 'p: 'b>(
    &'s self,
    prompt: &'p str,
    default: bool
) -> Cow<'b, str>[src]

Takes the prompt and returns the highlighted version (with ANSI color).

fn highlight_hint<'h>(&self, hint: &'h str) -> Cow<'h, str>[src]

Takes the hint and returns the highlighted version (with ANSI color).

fn highlight_candidate<'c>(
    &self,
    candidate: &'c str,
    completion: CompletionType
) -> Cow<'c, str>[src]

Takes the completion candidate and returns the highlighted version (with ANSI color).

Currently, used only with CompletionType::List.

fn highlight_char(&self, line: &str, pos: usize) -> bool[src]

Tells if line needs to be highlighted when a specific char is typed or when cursor is moved under a specific char.

Used to optimize refresh when a character is inserted or the cursor is moved.
