Method Descriptions

void _clear_highlighting_cache ( ) virtual

Virtual method which can be overridden to clear any local caches.

Dictionary _get_line_syntax_highlighting ( int line ) virtual const

Virtual method which can be overridden to return syntax highlighting data.

See get_line_syntax_highlighting for more details.

void _update_cache ( ) virtual

Virtual method which can be overridden to update any local caches.

void clear_highlighting_cache ( )

Clears all cached syntax highlighting data.

Then calls overridable method _clear_highlighting_cache.

Dictionary get_line_syntax_highlighting ( int line )

Returns syntax highlighting data for a single line. If the line is not cached, calls _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.

Example return:

var color_map = {
    0: {
        "color": Color(1, 0, 0)
    },
    5: {
        "color": Color(0, 1, 0)
    }
}

This will color columns 0-4 red, and columns 5-eol in green.

TextEdit get_text_edit ( ) const

Returns the associated TextEdit node.

void update_cache ( )

Clears then updates the SyntaxHighlighter caches. Override _update_cache for a callback.

Note: This is called automatically when the associated TextEdit node, updates its own cache.
