# This tool is used to prepare lookup tables of Unicode character properties
|
|
# needed by gfx code to support text shaping operations. The properties are
|
|
# read from the Unicode Character Database and compiled into multi-level arrays
|
|
# for efficient lookup.
|
|
#
|
|
# To regenerate the tables in nsUnicodePropertyData.cpp:
|
|
#
|
|
# (1) Download the current Unicode data files from
|
|
#
|
|
# http://www.unicode.org/Public/UNIDATA/
|
|
#
|
|
# NB: not all the files are actually needed; currently, we require
|
|
# - UnicodeData.txt
|
|
# - Scripts.txt
|
|
# - BidiMirroring.txt
|
|
# - BidiBrackets.txt
|
|
# - HangulSyllableType.txt
|
|
# - LineBreak.txt
|
|
# - ReadMe.txt (to record version/date of the UCD)
|
|
# - Unihan_Variants.txt (from Unihan.zip)
|
|
# though this may change if we find a need for additional properties.
|
|
#
|
|
# The Unicode data files listed above should be together in one directory.
|
|
#
|
|
# We also require the file
|
|
# http://www.unicode.org/Public/security/latest/xidmodifications.txt
|
|
# This file should be in a sub-directory "security" immediately below the
|
|
# directory containing the other Unicode data files.
|
|
#
|
|
# We also require the latest data file for UTR50, currently revision-13:
|
|
# http://www.unicode.org/Public/vertical/revision-13/VerticalOrientation-13.txt
|
|
# This file should be in a sub-directory "vertical" immediately below the
|
|
# directory containing the other Unicode data files.
|
|
#
|
|
#
|
|
# (2) Run this tool using a command line of the form
|
|
#
|
|
# perl genUnicodePropertyData.pl \
|
|
# /path/to/harfbuzz/src \
|
|
# /path/to/icu/common/unicode \
