NAME
fribidi_remove_bidi_marks - remove bidi marks out of an stringSYNOPSIS
#include <fribidi.h>FriBidiStrIndex fribidi_remove_bidi_marks
(
FriBidiChar *str,
const FriBidiStrIndex len,
FriBidiStrIndex *positions_to_this,
FriBidiStrIndex *position_from_this_list,
FriBidiLevel *embedding_levels
);
PARAMETERS
- FriBidiChar *str
- Input string to clean.
- const FriBidiStrIndex len
- Input string length.
- FriBidiStrIndex *positions_to_this
- List mapping positions to the order used in str.
- FriBidiStrIndex *position_from_this_list
- List mapping positions from the order used in str.
- FriBidiLevel *embedding_levels
- List of embedding levels.
DESCRIPTION
This function removes the bidi and boundary-neutral marks out of an string and the accompanying lists. It implements rule X9 of the Unicode Bidirectional Algorithm available at http://www.unicode.org/reports/tr9/#X9, with the exception that it removes U+200E LEFT-TO-RIGHT MARK and U+200F RIGHT-TO-LEFT MARK too.If any of the input lists are NULL, the list is skipped. If str is the visual string, then positions_to_this is positions_L_to_V and position_from_this_list is positions_V_to_L; if str is the logical string, the other way. Moreover, the position maps should be filled with valid entries.
A position map pointing to a removed character is filled with -1. By the way, you should not use embedding_levels if str is visual string.
For best results this function should be run on a whole paragraph, not lines; but feel free to do otherwise if you know what you are doing. Deprecated. Use fribidi_remove_special_chars instead.
RETURNS
New length of the string, or -1 if an error occured (memory allocation failure most probably).SEE ALSO
