<method name="get_line_syntax_highlighting">

<return type="Dictionary" />

<argument index="0" name="line" type="int" />
|
|
<description>
|
|
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.
