/**

|
|
* GtkCssLocation:
|
||
|
|
* @bytes: number of bytes parsed since the beginning
|
||
|
|
* @chars: number of characters parsed since the beginning
|
||
|
|
* @lines: number of full lines that have been parsed
|
||
|
|
* If you want to display this as a line number, you
|
||
|
|
* need to add 1 to this.
|
||
|
|
* @line_bytes: Number of bytes parsed since the last line break
|
||
|
|
* @line_chars: Number of characters parsed since the last line
|
||
|
|
* break
|
||
|
|
*
|
||
|
|
* @GtkCssLocation is used to present a location in a file - or other
|
||
|
|
* source of data parsed by the CSS engine.
|
||
|
|
*
|
||
|
|
* The @bytes and @line_bytes offsets are meant to be used to
|
||
|
|
* programmatically match data. The @lines and @line_chars offsets
|
||
|
|
* can be used for printing the location in a file.
|
||
|
|
*
|
||
|
|
* Note that the @lines parameter starts from 0 and is increased
|
||
|
|
* whenever a CSS line break is encountered. (CSS defines the C character
|
||
|
|
* sequences "\r\n", "\r", "\n" and "\f" as newlines.)
|
||
|
|
* If your document uses different rules for line breaking, you might want
|
||
|
|
* run into problems here.
