Base class for syntax highlighters. Provides syntax highlighting data to a [TextEdit].
Base class for syntax highlighters. Provides syntax highlighting data to a [TextEdit]. The associated [TextEdit] will call into the [SyntaxHighlighter] on an as-needed basis. [b]Note:[/b] A [SyntaxHighlighter] instance should not be used across multiple [TextEdit] nodes.
Virtual method which can be overridden to clear any local caches.
Virtual method which can be overridden to return syntax highlighting data. See [method get_line_syntax_highlighting] for more details.
Virtual method which can be overridden to update any local caches.
Clears all cached syntax highlighting data. Then calls overridable method [method _clear_highlighting_cache].
Returns syntax highlighting data for a single line. If the line is not cached, calls [method _get_line_syntax_highlighting] to calculate the data. The return [Dictionary] is column number to [Dictionary]. The column number notes the start of a region, the region will end if another region is found, or at the end of the line. The nested [Dictionary] contains the data for that region, currently only the key "color" is supported. [b]Example return:[/b] [codeblock] var color_map = { 0: { "color": Color(1, 0, 0) }, 5: { "color": Color(0, 1, 0) } } [/codeblock] This will color columns 0-4 red, and columns 5-eol in green.
Returns the associated [TextEdit] node.
Clears then updates the [SyntaxHighlighter] caches. Override [method _update_cache] for a callback. [b]Note:[/b] This is called automatically when the associated [TextEdit] node, updates its own cache.
