# Commands for regenerating ICU4C locale data (.txt files) from CLDR.
|
|
#
|
|
# The process requires local copies of
|
|
# - CLDR (the source of most of the data, and some Java tools)
|
|
# - ICU4J (used only for checking the converted data)
|
|
# - ICU4C (the destination for the new data, and the source for some of it)
|
|
#
|
|
# For an official CLDR data integration into ICU, these should be clean, freshly
|
|
# checked-out. For released CLDR sources, an alternative to checking out sources
|
|
# for a given version is downloading the zipped sources for the common (core.zip)
|
|
# and tools (tools.zip) directory subtrees from the Data column in
|
|
# [http://cldr.unicode.org/index/downloads].
|
|
#
|
|
# The versions of each of these must match. Included with the release notes for
|
|
# ICU is the version number and/or a CLDR svn tag name for the revision of CLDR
|
|
# that was the source of the data for that release of ICU.
|
|
#
|
|
# Besides a standard JDK, the process also requires ant
|
|
# (http://ant.apache.org/),
|
|
# plus the xml-apis.jar from the Apache xalan package
|
|
# (http://xml.apache.org/xalan-j/downloads.html).
|
|
#
|
|
# Note: Enough things can (and will) fail in this process that it is best to
|
|
# run the commands separately from an interactive shell. They should all
|
|
# copy and paste without problems.
|
|
#
|
|
# It is often useful to save logs of the output of many of the steps in this
|
|
# process. The commands below put log files in /tmp; you may want to put them
|
|
# somewhere else.

#
|
|
# CLDR dtd caching
|
|
#
|
|
# Parts of the build process (notably building the new ICU data files in step 4)
|
|
# require http: access to files in the CLDR repository; for example, processing
|
|
# the files in icu4c/source/data/xml/ may require access to
|
|
# http://www.unicode.org/repos/cldr/trunk/common/dtd/ldml.dtd
|
|
#
|
|
# Unless you cache the dtds locally by
|
|
# 1. creating a temp directory e.g. ~/.cldrdtd
|
|
# 2. setting CLDR_DTD_CACHE to it e.g. -DCLDR_DTD_CACHE=~/.cldrdtd
|
|
# your system will make excessive network requests, which will result in the
|
|
# Unicode server blocking access.
|
|
#
|
|
#----
|
|
#
|
|
# There are several environment variables that need to be defined.
|
|
#
|
|
# a) Java- and ant-related variables
|
|
#
|
|
# JAVA_HOME: Path to JDK (a directory, containing e.g. bin/java, bin/javac,
|
|
# etc.); on many systems this can be set using
|
|
# `/usr/libexec/java_home`.
|
|
#
|
|
# ANT_OPTS: You may want to set:
|
|
#
|
|
# -Xmx4096m, to give Java more memory; otherwise it may run out
|
|
# of heap.
|
|
# -DCLDR_DTD_CACHE=~/.cldrdtd (or some other temp directory
|
|
# that already exists), to reduce frequent http: access to dtds
|
|
# and consequent blockage by Unicode server.
|
|
#
|
|
# b) CLDR-related variables
|
|
#
|
|
# CLDR_DIR: Path to root of CLDR sources, below which are the common and
|
|
# tools directories.
|
|
# CLDR_CLASSES: Path to the CLDR Tools classes directory. If not set, defaults
|
|
# to $CLDR_DIR/tools/java/classes
|
|
#
|
|
# c) ICU-related variables
|
|
# These variables only need to be set if you're directly reusing the
|
|
# commands below.
|
|
#
|
|
# ICU4C_DIR: Path to root of ICU4C sources, below which is the source dir.
|
|
#
|
|
# ICU4J_ROOT: Path to root of ICU4J sources, below which is the main dir.
|
|
#
|
|
#----
|
|
#
|
|
# If you are adding or removing locales, or specific kinds of locale data,
|
|
# there are some xml files in the ICU sources that need to be updated (these xml
|
|
# files are used in addition to the CLDR files as inputs to the CLDR data build
|
|
# process for ICU):
|
|
#
|
|
# icu4c/source/data/icu-config.xml - Update <locales> to add or remove
|
|
# CLDR locales for inclusion in ICU. Update <paths> to prefer
|
|
# alt forms for certain paths, or to exclude certain paths; note
|
|
# that <paths> items can only have draft or alt attributes.
|
|
#
|
|
# Note that if a language-only locale (e.g. "de") is included in
|
|
# <locales>, then all region sublocales for that language that
|
|
# are present in CLDR data (e.g. "de_AT", "de_BE", "de_CH", etc.)
|
|
# should also be included in <locales>, per PMC policy decision
|
|
# 2012-05-02 (see http://bugs.icu-project.org/trac/ticket/9298).
|
|
#
|
|
# icu4c/source/data/build.xml - If you are adding or removing break
|
|
# iterators, you need to update <fileset id="brkitr" ...> under
|
|
# <target name="clean" ...> to clean the correct set of files.
|
|
#
|
|
# If there are new CLDR resource bundle types, you may need to
|
|
# updated the <remapper> sections to put these in the correct
|
|
# data subfolder for ICU.
|
|
#
|
|
# icu4c/source/data/xml/ - If you are adding a new locale, break
|
|
# iterator, collation tailoring, or rule-based number formatter,
|
|
# you may need to add a corresponding xml file in (respectively)
|
|
# the main/, brkitr/, collation/, or rbnf/ subdirectory here.
|
|
#
|
|
#----
|
|
#
|
|
# For an official CLDR data integration into ICU, there are some additional
|
|
# considerations:
|
|
#
|
|
# a) Don't commit anything in ICU sources (and possibly any changes in CLDR
|
|
# sources, depending on their nature) until you have finished testing and
|
|
# resolving build issues and test failures for both ICU4C and ICU4J.
|
|
#
|
|
# b) There are version numbers that may need manual updating in CLDR (other
|
|
# version numbers get updated automatically, based on these):
|
|
#
|
|
# common/dtd/ldml.dtd - update cldrVersion
|
|
# common/dtd/ldmlBCP47.dtd - update cldrVersion
|
|
# common/dtd/ldmlSupplemental.dtd - update cldrVersion
|
|
# common/dtd/ldmlSupplemental.dtd - updateunicodeVersion
|
|
# keyboards/dtd/ldmlKeyboard.dtd - update cldrVersion
|
|
# tools/java/org/unicode/cldr/util/CLDRFile.java - update GEN_VERSION
|
|
#
|
|
# c) After everything is committed, you will need to tag the CLDR, ICU4J, and
|
|
# ICU4C sources that ended up being used for the integration; see step 17
|
|
# below.

# This process uses ant with ICU's data/build.xml and data/icu-config.xml to

# operate (via CLDR's ant/CLDRConverterTool.java and ant/CLDRBuild.java) the
|
|
# necessary CLDR tools including LDML2ICUConverter, ConvertTransforms, etc.
|

#
|

# Running "ant setup" is not required, but it will print useful errors to

# from the Survey Tool can result in thousands of failures (in many cases, one

|
# CLDR data fix can resolve hundreds of test failures). If the error is caused

|
|
# appropriate, and repeating steps 4-7 and 9 until there are no errors.
|
|
|
|
# 11. Now with ICU4J, build and test without new data first, to verify that
