# 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
# - EastAsianWidth.txt
# - BidiMirroring.txt
# - HangulSyllableType.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/UCD-directory
#
# This will generate (or overwrite!) the files
#
# nsUnicodePropertyData.cpp
# nsUnicodeScriptCodes.h
#
# in the current directory.

# NOTE that HB_SCRIPT_* constants are now "tag" values, NOT sequentially-allocated
# script codes as used by Glib/Pango/etc.
# We therefore define a set of MOZ_SCRIPT_* constants that are script _codes_
# compatible with those libraries, and map these to HB_SCRIPT_* _tags_ as needed.
# CHECK that this matches Pango source (as found for example at
# http://git.gnome.org/browse/pango/tree/pango/pango-script.h)
# for as many codes as that defines (currently up through Unicode 5.1)
# and the GLib enumeration
# http://developer.gnome.org/glib/2.30/glib-Unicode-Manipulation.html#GUnicodeScript
# (currently defined up through Unicode 6.0).
# Constants beyond these may be regarded as unstable for now, but we don't actually
# depend on the specific values.
