| # Checking out the CLDR Archive |
| |
| A number of the tools in CLDR depend on access to older versions. These tools include: |
| |
| - [Generating Charts](https://cldr.unicode.org/development/cldr-big-red-switch/generating-charts) |
| - [Update Validity XML](https://cldr.unicode.org/development/updating-codes/update-validity-xml) |
| - [Updating English/Root](https://cldr.unicode.org/development/cldr-development-site/updating-englishroot) |
| - \[Note: add others when we find them] |
| - Some tests |
| - TestCompatibility.java |
| - TestTransforms.java |
| - TestValidity.java |
| - Some other tools (typically when given a version argument on the command line) |
| - FindPluralDifferences |
| - ... |
| |
| ### Here's how to do that. |
| |
| 1. Create an archive directory **cldr\-archive**. The Simplest is if it on the same level as your local CLDR repository. In other words, if your [CLDR\_DIR](https://cldr.unicode.org/development/cldr-development-site/running-cldr-tools) is .../workspace/cldr, then create the directory **…/workspace/cldr\-archive** <br> |
| (Note: The Java property **ARCHIVE** can be used to overide the path to cldr\-archive). |
| 2. Open up ToolConstants.java and look at ToolConstants.CLDR\_VERSIONS. You'll see something like: |
| 1. **public static final** List\<String\> ***CLDR\_VERSIONS*** \= ImmutableList.of( |
| 2. "1\.1\.1", |
| 3. "1\.2", |
| 4. "1\.3", |
| 5. "1\.4\.1", |
| 6. "1\.5\.1", |
| 7. "1\.6\.1", |
| 8. "1\.7\.2", |
| 9. "1\.8\.1", |
| 10. ... |
| 11. "41\.0" |
| 12. // add to this once the release is final! |
| 13. ); |
| - NOTE: this should also match CldrVersion.java (those two need to be merged together) |
| 3. Add the just\-released version, such as "**42\.0**" to the list above |
| - Also update **DEV\_VERSION** to "43" (the next development version) |
| - Finally, update CldrVersion.java and make similar changes. |
| 4. Now, run the tool **org.unicode.cldr.tool.CheckoutArchive** |
| - Or from the command line:<br> |
| **mvn \-DCLDR\_DIR\=** *path\_to/cldr* **\-\-file\=tools/pom.xml \-pl cldr\-code compile \-DskipTests\=true exec:java \-Dexec.mainClass\=org.unicode.cldr.tool.CheckoutArchive \-Dexec.args\=""** |
| - Note other options for this tool: |
| *\-\-help* will give help |
| *\-\-prune* will run a 'git workspace prune' before proceeding |
| *\-\-echo* will just show the commands that would be run, without running anything |
| (For example, **\-Dexec.args\="\-\-prune"** in the above command line) |
| |
| The end result (where you need all of the releases) looks something like the following: |
| |
|  |
| |
| ## Advanced Configuration |
| |
| - You can set the property **\-DCLDR\_ARCHIVE** to point to a different parent directory for the archive |
| - You can set **\-DCLDR\_HAS\_ARCHIVE\=false** to tell unit tests and tools not to look for the archive |
