unigenwidth(1) Generate C code for POSIX wcwidth and wcswidth functions

SYNOPSIS


unigenwidth unifont.hex combining.txt

DESCRIPTION

unigenwidth reads a collection of glyphs in Unifont's .hex format, then reads a list of combining characters as a hexadecimal list. From these two files, it produces C code to implement the POSIX wcwidth(3) and wcswidth(3) functions. The format of these definitions is based upon POSIX 1003.1-2008 System Interfaces, pages 2251 and 2241, respectively.

EXAMPLE

Sample usage:

unigenwidth unifont.hex combining.txt > wccode.c

FILES

*.hex files for Unifont glyph data; combining.txt for combining code points.
