     1.7 +# Commands for regenerating ICU4C locale data (.txt files) from CLDR.
     1.8 +#
     1.9 +# The process requires local copies of
    1.10 +#    - CLDR (the source of most of the data, and some Java tools)
    1.11 +#    - ICU4J  (used only for checking the converted data)
    1.12 +#    - ICU4C  (the destination for the new data, and the source for some of it)
    1.13 +#             (Either check out ICU4C from Subversion, or download the additional 
    1.14 +#              icu4c-*-data.zip file so that the icu/source/data/ directory is fully
    1.15 +#              populated.)
    1.16 +#
    1.17 +# For an official CLDR data integration into ICU, these should be clean, freshly
    1.18 +# checked-out. For released CLDR sources, an alternative to checking out sources
    1.19 +# for a given version is downloading the zipped sources for the common (core.zip)
    1.20 +# and tools (tools.zip) directory subtrees from the Data column in
    1.21 +# [http://cldr.unicode.org/index/downloads].
    1.22 +#
    1.23 +# The versions of each of these must match. Included with the release notes for
    1.24 +# ICU is the version number and/or a CLDR svn tag name for the revision of CLDR
    1.25 +# that was the source of the data for that release of ICU.
    1.26 +#
    1.27 +# Note: Some versions of the OpenJDK will not build the CLDR java utilities.
    1.28 +#   If you see compilation errors complaining about type incompatibilities with
    1.29 +#   functions on generic classes, try switching to the Sun JDK.
    1.30 +#
    1.31 +# Besides a standard JDK, the process also requires ant
    1.32 +# (http://ant.apache.org/),
    1.33 +# plus the xml-apis.jar from the Apache xalan package
    1.34 +# (http://xml.apache.org/xalan-j/downloads.html).
    1.35 +#
    1.36 +# Note: Enough things can (and will) fail in this process that it is best to
    1.37 +#   run the commands separately from an interactive shell. They should all
    1.38 +#   copy and paste without problems.
    1.39 +#
    1.40 +# It is often useful to save logs of the output of many of the steps in this
    1.41 +# process. The commands below put log files in /tmp; you may want to put them
    1.42 +# somewhere else.
    1.43 +#
    1.44 +#----
    1.45 +#
    1.46 +# There are several environment variables that need to be defined.
    1.47 +#
    1.48 +# a) Java- and ant-related variables
    1.49 +#
    1.50 +# JAVA_HOME:     Path to JDK (a directory, containing e.g. bin/java, bin/javac,
    1.51 +#                etc.); on many systems this can be set using
    1.52 +#                `/usr/libexec/java_home`.
    1.53 +#
    1.54 +# ANT_OPTS:      You may want to set:
    1.55 +#
    1.56 +#                -Xmx1024m, to give Java more memory; otherwise it may run out
    1.57 +#                 of heap.
    1.58 +#
    1.59 +# b) CLDR-related variables
    1.60 +#
    1.61 +# CLDR_DIR:      Path to root of CLDR sources, below which are the common and
    1.62 +#                tools directories.
    1.63 +# CLDR_CLASSES:  Defined relative to CLDR_DIR. It only needs to be set if you
    1.64 +#                are not running ant jar for CLDR and have a non-default output
    1.65 +#                folder for cldr-tools classes.
    1.66 +#
    1.67 +# c) ICU-related variables
    1.68 +# These variables only need to be set if you're directly reusing the
    1.69 +# commands below.
    1.70 +#
    1.71 +# ICU4C_DIR:     Path to root of ICU4C sources, below which is the source dir.
    1.72 +#
    1.73 +# ICU4J_ROOT:    Path to root of ICU4J sources, below which is the main dir.
    1.74 +#
    1.75 +#----
    1.76 +#
    1.77 +# If you are adding or removing locales, or specific kinds of locale data,
    1.78 +# there are some xml files in the ICU sources that need to be updated (these xml
    1.79 +# files are used in addition to the CLDR files as inputs to the CLDR data build
    1.80 +# process for ICU):
    1.81 +#
    1.82 +#    icu/trunk/source/data/icu-config.xml - Update <locales> to add or remove
    1.83 +#                CLDR locales for inclusion in ICU. Update <paths> to prefer
    1.84 +#                alt forms for certain paths, or to exclude certain paths; note
    1.85 +#                that <paths> items can only have draft or alt attributes.
    1.86 +#
    1.87 +#                Note that if a language-only locale (e.g. "de") is included in
    1.88 +#                <locales>, then all region sublocales for that language that
    1.89 +#                are present in CLDR data (e.g. "de_AT", "de_BE", "de_CH", etc.)
    1.90 +#                should also be included in <locales>, per PMC policy decision
    1.91 +#                2012-05-02 (see http://bugs.icu-project.org/trac/ticket/9298).
    1.92 +#
    1.93 +#    icu/trunk/source/data/build.xml - If you are adding or removing break
    1.94 +#                iterators, you need to update  <fileset id="brkitr" ...> under
    1.95 +#                <target name="clean" ...> to clean the correct set of files.
    1.96 +#
    1.97 +#    icu/trunk/source/data/xml/      - If you are adding a new locale, break
    1.98 +#                iterator, collation tailoring, or rule-based number formatter,
    1.99 +#                you may need to add a corresponding xml file in (respectively)
   1.100 +#                the main/, brkitr/, collation/, or rbnf/ subdirectory here.
   1.101 +#
   1.102 +#----
   1.103 +#
   1.104 +# For an official CLDR data integration into ICU, there are some additional
   1.105 +# considerations:
   1.106 +#
   1.107 +# a) Don't commit anything in ICU sources (and possibly any changes in CLDR
   1.108 +#    sources, depending on their nature) until you have finished testing and
   1.109 +#    resolving build issues and test failures for both ICU4C and ICU4J.
   1.110 +#
   1.111 +# b) There are version numbers that may need manual updating in CLDR (other
   1.112 +#    version numbers get updated automatically, based on these):
   1.113 +#
   1.114 +#    common/dtd/ldml.dtd                            - update cldrVersion
   1.115 +#    common/dtd/ldmlBCP47.dtd                       - update cldrVersion
   1.116 +#    common/dtd/ldmlSupplemental.dtd                - update cldrVersion
   1.117 +#    tools/java/org/unicode/cldr/util/CLDRFile.java - update GEN_VERSION
   1.118 +#
   1.119 +# c) After everything is committed, you will need to tag the CLDR, ICU4J, and
   1.120 +#    ICU4C sources that ended up being used for the integration; see step 17
   1.121 +#    below.
