+# 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.

+# 2. Build the CLDR Java tools
+# Optionally build the jar, but ant will look inside the classes directory anyway
+
+cd $CLDR_DIR/tools/java
+ant all
+#ant jar
+
+# 3. Configure ICU4C, build and test without new data first, to verify that
+# there are no pre-existing errors. Here <platform> is the runConfigureICU
+# code for the platform you are building, e.g. Linux, MacOSX, Cygwin.
+
+cd $ICU4C_DIR/source
+./runConfigureICU <platform>
+make all 2>&1 | tee /tmp/icu4c-oldData-makeAll.txt
+make check 2>&1 | tee /tmp/icu4c-oldData-makeCheck.txt
+
+# 4. Build the new ICU4C data files; these include .txt files and .mk files.
+# These new files will replace whatever was already present in the ICU4C sources.
+# 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.
+# This process will take several minutes.
+# Keep a log so you can investigate anything that looks suspicious.
+#
+# Running "ant setup" is not required, but it will print useful errors to
+# debug issues with your path when it fails.
+#
+# If you see timeout errors when building the rbnf data, for example, then you are
+# likely not using a CLDR dtd cache; see "CLDR dtd caching" above. If you are using
+# a dtd cache and are still having timeout problems, the IP address of your system
+# may have been blocked due to previous excessive access. In this case you may need
+# to contact a Unicode sysadmin to restore access.
+#
+# Unfortunately, even if you have your DTD cache variable enabled, you may still
+# get blocked and unable to populate your cache because of multiple successive
+# requests to download the required DTD files. It is recommended that you
+# pre-populate your cache as shown above in step 1d.
+
+cd $ICU4C_DIR/source/data
+ant setup
+ant clean
+ant all 2>&1 | tee /tmp/cldr-newData-buildLog.txt
+
+# 5. Check which data files have modifications, which have been added or removed
+# (if there are no changes, you may not need to proceed further). Make sure the
+# list seems reasonable.
+
+git status
+
+# 6. Fix any errors, investigate any warnings. Currently for example there are
+# a few warnings of the following form in rbnf files:
+# [cldr-build] Warning: no version match with: $Revisionā¹$
+#
+# Fixing may entail modifying CLDR source data or tools - for example,
+# updating the validSubLocales for collation data (file a bug if appropriate).
+# Repeat steps 4-5 until there are no build errors and no unexpected
+# warnings.
+
+# 7. Now rebuild ICU4C with the new data and run make check tests.
+# Again, keep a log so you can investigate the errors.
+cd $ICU4C_DIR/source
+
+# 7a. If any files were added or removed (likely), re-run configure:
+./runConfigureICU <platform>
+make clean
+
+# 7b. Now do the rebuild.
+make check 2>&1 | tee /tmp/icu4c-newData-makeCheck.txt
+
+# 8. Investigate each test case failure. The first run processing new CLDR data
+# 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
+# by bad CLDR data, then file a CLDR bug, fix the data, and regenerate from
+# step 4. If the data is OK but the testcase needs to be updated because the
+# data has legitimately changed, then update the testcase. You will check in
+# the updated testcases along with the new ICU data at the end of this process.
+# Note that if the new data has any differences in structure, you will have to
+# update test/testdata/structLocale.txt or /tsutil/cldrtest/TestLocaleStructure
+# may fail.
+# Repeat steps 4-7 until there are no errors.
+
+# 9. Now run the make check tests in exhaustive mode:
+
+cd $ICU4C_DIR/source
+export INTLTEST_OPTS="-e"
+export CINTLTST_OPTS="-e"
+make check 2>&1 | tee /tmp/icu4c-newData-makeCheckEx.txt
+
+# 10. Again, investigate each failure, fixing CLDR data or ICU test cases as
+# 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
+# there are no pre-existing errors (or at least to have the pre-existing errors
+# as a base for comparison):
+
+cd $ICU4J_ROOT
+ant all 2>&1 | tee /tmp/icu4j-oldData-antAll.txt
+ant check 2>&1 | tee /tmp/icu4j-oldData-antCheck.txt
+
+# 12. Transfer the data to ICU4J:
+cd $ICU4C_DIR/source
+
+# 12a. You need to reconfigure ICU4C to include the unicore data.
+ICU_DATA_BUILDTOOL_OPTS=--include_uni_core_data ./runConfigureICU <platform>
+
+# 12b. Now build the jar files.
+cd $ICU4C_DIR/source/data
+# The following 2 lines are required to include the unicore data:
+ make clean
+ make -j6
+make icu4j-data-install
+cd $ICU4C_DIR/source/test/testdata
+make icu4j-data-install
+
+# 13. Now rebuild ICU4J with the new data and run tests:
+# Keep a log so you can investigate the errors.
+
+cd $ICU4J_ROOT
+ant check 2>&1 | tee /tmp/icu4j-newData-antCheck.txt
+
+# 14. Investigate test case failures; fix test cases and repeat from step 12,
+# or fix CLDR data and repeat from step 4, as appropriate, until there are no
+# more failures in ICU4C or ICU4J (except failures that were present before you
+# began testing the new CLDR data).
+
+# 15. Check the file changes; then git add or git rm as necessary, and
+# commit the changes.
+
+cd $HOME/icu/
+cd ..
+git status
+# add or remove as necessary
+# commit
+
+# 16. For an official CLDR data integration into ICU, now tag the CLDR and
+# ICU sources with an appropriate CLDR milestone (you can check previous
+# tags for format), e.g.:
+
+svn copy svn+ssh://unicode.org/repos/cldr/trunk \
+svn+ssh://unicode.org/repos/cldr/tags/release-NNN \
+--parents -m "cldrbug nnnn: tag cldr sources for NNN"
+

+git tag ...
