+
+# Updating English/Root
+
+Whenever you update English or Root, there is one additional step that needs to be done for the vetting viewer and tests to work properly.
+
+Update CldrVersion.java to have the newest release in the list.
+
+## Run GenerateBirth
+
+The tool is in tools/java/org/unicode/cldr/tool/GenerateBirth.java. It requires a set of sources from all previous major CLDR release, trunk, and a generation directory. These three directories must be structured as follows. The tool takes environment parameters for the second two.
+
+**cldr (set with \-t \<target\>, default\=CldrUtility.BASE\_DIRECTORY, set with environment variable \-DCLDR\_DIR)**
+
+... common/ ... tools/ java/ (apps such as GenerateBirth are run from here) ...
+
+**CldrUtility.ARCHIVE\_DIRECTORY**
+
+1. Create the archive ([Creating the Archive](https://cldr.unicode.org/development/creating-the-archive)) with all releases (if you don't have it already)
+2. The archive directory should have the latest version of every major and minor version (where versions before 21\.0 have the major version split across the top two fields).
+3. You will probably need to modify both CldrVersion.java and ToolConstants.java to bring them up to date.
+
+**log (set with \-l \<log\>, default\=CldrUtility.UTIL\_DATA\_DIR, set with CLDR\_DIR** 
+
+Pass an argument for \-t to specify the output directory. Takes a few minutes to run (and make sure you have set Java with enough memory)!
+
+The tool generates (among other things) the following two binary files (among others) in the output directory specified with \-t: 
+
+- **outdated.data**
+- **outdatedEnglish.data**
+
+Replacing the previous versions in /cldr/tools/java/org/unicode/cldr/util/data/births/. These files are used to support OutdatedPaths.java, which is used in CheckNew.
+
+Readable data is found in https://github.com/unicode\-org/cldr\-staging/tree/master/births/\* That should also be checked in, for comparison over time. Easiest to read if you paste into a spreadsheet!
+
+## Binary File Format
+
+| outdatedEnglish.data | outdated.data |
+|---|---|
+| **int:size** | **str:locale** |
+| long:pathId str:oldValue | **int:size** |
+| long:pathId str:oldValue | long:pathId |
+| ... | long:pathId |
+|  | ... |
+|  | **str:locale** |
+|  | **int:size** |
+|  | long:pathId |
+|  | long:pathId |
+|  | ... |
+| **\$END\$** | **\$END\$** |
+| ~50KB | ~100KB |
+
+In a limited release, the file **SubmissionLocales.java** is set up to allow just certain locales and paths in those locales.
+
+## Testing
+
+Make sure TestOutdatedPaths.java passes. It may take some modifications, since it depends on the exact data.
+
+Run TestCheckCLDR and TestBasic with the option **\-prop:logKnownIssue\=false** (that option is important!). This checks that the Limited Submission is set up properly and that SubmissionLocales are correct.
+
+
+
+If you run into any problems, look below at debugging.
+
+**Check in the files**
+
+Eg https://github.com/unicode-org/cldr/pull/243
+
+## Debugging
+
+It also generates readable log files for double checking. These will be in {workspace}/cldr\-aux/births/\<version\>/, that is: CLDRPaths.AUX\_DIRECTORY \+ "births/" \+ trunkVersion. Examples: https://unicode.org/repos/cldr-aux/births/35.0/en.txt, https://unicode.org/repos/cldr-aux/births/35.0/fr.txt.
+
+Their format is the following (TSV \= tab\-delimited\-values) — to view, it is probably easier to copy the files into a spreadsheet. 
+
+- English doesn't have the E... values, but is a complete record.
+- Other languages only have lines where the English value is more recently changed (younger) than the native’s.
+- So what the first line below says is that French has "bengali" dating back to version 1\.1\.1, while English has "Bangla" dating back to version 30\.
+
+| Loc | Version | Value | PrevValue | EVersion | EValue | EPrevValue | Path |

+
+A value of � indicates that there is no value for that version.

+# Documenting CLDR Tools
+
+*Developers: Make sure your tool is easily accessible from the command line.*
+
+You can add the @CLDRTool annotation to any class in cldr\-code that has a main() function, and it will be documented as part of the JAR cldr\-code.jar is used.
+
+See [CLDR Tools](https://cldr.unicode.org/development/cldr-tools) for general information about obtaining and using CLDR tools.
+
+## Coding it
+
+An example from ConsoleCheckCLDR.java will start us out here
+
+  @CLDRTool(alias \= "check",
+
+  description \= "Run CheckCLDR against CLDR data")
+
+  public class ConsoleCheckCLDR { …
+
+Then, calling ```java -jar cldr-tools.jar -l``` produces:
+
+  *check \- Run CheckCLDR against CLDR data*
+
+&emsp;&emsp;*\<http://cldr.unicode.org/tools/check\>*
+
+&emsp;&emsp;*\= org.unicode.cldr.test.ConsoleCheckCLDR*
+
+And then ```java -jar cldr-tools.jar check``` can be used to run this tool. All additional arguments after "check" are passed to **ConsoleCheckCLDR.main()** as arguments.
+
+Note these annotation parameters. Only "alias" is required.
+
+- **alias** \- used from the command line instead of the full class name. Also forms part of the default URL for documentation.
+- **description** \- a short description of the tool.
+
+Additional parameters:
+
+- **url** \- you can specify a custom URL for the tool. This is displayed with the listing.
+- **hidden** \- if non\-empty, this specifies a reason to *not* show the tool when running "java \-jar" without "\-l". For example, the main() function may be a less\-useful internal tool, or a test.
+## Documenting it
+
+Assuming your tools’s alias is *myalias,* create a new subpage with the URL http://cldr.unicode.org/tools/myalias (a subpage of [CLDR Tools](https://cldr.unicode.org/development/cldr-tools)). Fill this page out with information about how to use your tool.

+
+# 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:
+
+![alt-text](../images/development/creatingTheArchive.png)
+
+## 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

+# Running Tests
+
+You will always need to run tests when you do a check\-in.
+
+1. Preconditions
+	- If you change the DTD, be sure to read and follow [Updating DTDs](https://cldr.unicode.org/development/updating-dtds) first.
+	- If you added a new feature or fixed a significant bug, add a unit test for it. 
+		- See unittest/NumberingSystemsTest as an example.
+		- Remember to add to unittest/TestAll
+2. Run **TestAll \-e**
+	- These are the unit tests in exhaustive mode
+	- If you are doing something you know to be simple, you could do the shorter run of just **TestAll**
+3. Run **ConsoleCheckCLDR \-e \-z final\_testing \-S common,seed**
+	- This runs the same set of test that the Survey Tool does.
+	- If you know what you are doing, you can run a set of filtered tests.
+4. Other tests
+	1. The unit tests are not complete, so you get a better workout if you are doing anything fancy by running:
+	2. [**NewLdml2IcuConverter**](https://cldr.unicode.org/development/coding-cldr-tools/newldml2icuconverter)
+	3. [**Generating Charts**](https://cldr.unicode.org/development/cldr-big-red-switch/generating-charts)
+		1. If you have interesting new data, write a chart for it. See subclasses of Chart.java for examples.
+
+## Running tests on the command line
+
+```bash
+$ export CLDR_DIR=/path/to/svn/root/for/cldr
+
+$ cd $CLDR_DIR/tools/java && ant all
+
+$ cd $CLDR_DIR/tools/cldr-unittest && ant unittestExhaustive datacheck
+```
+
+\[TODO: add more commands here; can't we automate all this into a single build rule for ant?] TODO: [TODOL ticket:8864](http://unicode.org/cldr/trac/ticket/8864) 
+
+## Debugging
+
+\[TODO: add more tips here]
+
+### Regexes
+
+We use a lot of regexes!
+
+1. There is org.unicode.cldr.util.RegexUtilities.showMismatch (and related methods) that are really useful in debugging cases where regexes fail. You hand it a pattern or matcher and a string, and it shows how far the regex got before it failed.
+2. To debug RegexLookup, there is a special call you can make where you pass in a set. On return, that set is filled with a set of strings showing how far each of the regex patterns progressed. You can thus see why a string didn't match as expected.
