New CLDR Developers

Here is a quick overview of what you need to know to do development work on CLDR. 

First, you need to have accounts set up for you on:
  1. trac — for getting and handling bug reports
  2. SVN — for submitting code / data
  3. cldr-dev — for discussions of issues, questions, etc.
  4. Google Docs — to view/edit the CLDR agenda and internal documents
  5. Google Sites — only if you are going to edit this website
If you don't get emails about these, contact Rick or other CLDR contacts. It is handy, though not necessary, for you to use a gmail account for the last two of these. Many people use a different account than their internal company email address.

Warning: some of these pages get stale. Ask questions on cldr-dev if you run into problems; you or the responder should also fix the stale page.

Next, get your Eclipse environment set up properly.
  1. http://cldr.unicode.org/development/eclipse-setup
  2. http://cldr.unicode.org/development/running-survey-tool/eclipse
Run the CLDR tests to be sure they pass before beginning work:

Command line:
  1. Be at root of SVN working directory
  2. cd tools/java
  3. ant all
  4. cd ../cldr-unittest
  5. ant check

  6. If you see test errors, for instance TestBasic/TestDtdComparison fails, run only the failing test like so:

    ant -Druncheck.arg="-v TestBasic/TestDtdComparison" check

    The -v tells test script to show stack trace at the test failure for debugging.

  7. To get all parameters that could be passed at runcheck.arg, run

    ant -Druncheck.arg="-?" check
Via eclipse:
  1. Go here
Once you are all set up, be sure to read the development process, for how to handle tickets, when you can't make changes, etc.

Other useful pages are under CLDR Development Site; you can also use the search box. Also, UTS #35: Unicode Locale Data Markup Language (LDML) is the specification of the XML format used for CLDR data, including the interpretation of the CLDR data.
