<method name="get_line_syntax_highlighting">
<return type="Dictionary">
</return>
<argument index="0" name="line" type="int">
</argument>
<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.
