<method name="get_line_syntax_highlighting">
|
|
<return type="Dictionary" />
|
|
<param index="0" name="line" type="int" />
|
|
<description>
|
|
Returns the syntax highlighting data for the line at index [param line]. If the line is not cached, calls [method _get_line_syntax_highlighting] first to calculate the data.
|
|
Each entry is a column number containing a nested [Dictionary]. The column number denotes 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 [code]"color"[/code] is supported.
|
|
[b]Example:[/b] Possible return value. This means columns [code]0[/code] to [code]4[/code] should be red, and columns [code]5[/code] to the end of the line should be green:
|
|
[codeblock]
|
|
{
|
|
0: {
|
|
"color": Color(1, 0, 0)
|
|
},
|
|
5: {
|
|
"color": Color(0, 1, 0)
|
|
}
|
|
}
|
|
[/codeblock]

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.
