# Generate utt tables. Note: this script has now been converted to Python 3.
|
|
|
|
# The source file pcre2_tables.c contains (amongst other things), a table that
|
|
# is indexed by script name. In order to reduce the number of relocations when
|
|
# loading the library, the names are held as a single large string, with
|
|
# offsets in the table. This is tedious to maintain by hand. Therefore, this
|
|
# script is used to generate the table. The output is sent to stdout; usually
|
|
# that should be directed to a temporary file. Then pcre2_tables.c can be
|
|
# edited by replacing the relevant definitions and table therein with the
|
|
# temporary file.

|
# Modified by PH 17-March-2009 to generate the more verbose form that works
|
|
# for UTF-support in EBCDIC as well as ASCII environments.
|
|
# Modified by PH 01-March-2010 to add new scripts for Unicode 5.2.0.
|
|
# Modified by PH 04-May-2010 to add new "X.." special categories.
|
|
# Modified by PH 30-April-2011 to add new scripts for Unicode 6.0.0
|
|
# Modified by ChPe 30-September-2012 to add this note; no other changes were
|
|
# necessary for Unicode 6.2.0 support.
|
|
# Modfied by PH 26-February-2013 to add the Xuc special category.
|
|
# Comment modified by PH 13-May-2014 to update to PCRE2 file names.
|
|
# Script updated to Python 3 by running it through the 2to3 converter.
|
|
# Added script names for Unicode 7.0.0, 20-June-2014.
|
|
# Added script names for Unicode 8.0.0, 19-June-2015.
