Implementations

impl<'a> CodeView<'a>

pub fn new(id: &'a str, text: &'a str) -> Self

pub fn lang(self, lang: Option<&'a str>) -> Self

The language (a name, alias or extension; see ashlar_syntax::Lang::from_name). Unknown or None shows plain text.

pub fn lang_for_path(self, path: &str) -> Self

The language for a file path ("src/main.rs").

pub fn revision(self, revision: u64) -> Self

Bump when the text changes. (A change of the text’s address or length is noticed anyway; an edit that keeps both needs a new revision.)

pub fn wrap(self, wrap: bool) -> Self

Wrap long lines at the view’s width (off: long lines are clipped).

pub fn line_numbers(self, yes: bool) -> Self

Show the line-number gutter (on by default).

pub fn theme(self, theme: &'a SyntaxTheme) -> Self

Token colours (default: SyntaxTheme::from_tokens of the current tokens).

pub fn highlighter(self, h: &'a dyn Highlighter) -> Self

The highlighting engine (default: Builtin).

pub fn marks(self, marks: &'a [Range<usize>]) -> Self

Byte ranges to mark (search hits), sorted by start and not overlapping.

pub fn scroll_to_line(self, line: Option<usize>) -> Self

Scroll so this line (0-based) is visible.

pub fn max_height(self, h: f32) -> Self

Cap the view’s height (default: the available height).

pub fn show(self, ui: &mut Ui) -> CodeViewResponse
