|
||
| This document explains how to update the C++ and Java version of the MeasureUnit | ||
| class with new CLDR data. | ||
|
|
||
| Code is generated by running MeasureUnitTest.java unit tests, which writes | ||
| generated code to System.out. Two ways to access this: | ||
|
|
||
| 1. Within **eclipse**: | ||
| - Open MeasureUnitTest.java, run it by clicking on the green play button on | ||
| menu bar. | ||
| - Copy the generated code from the eclipse console to the clipboard. | ||
|
|
||
| 2. With **ant**: | ||
| - Run: `ant checkTest | ||
| -Dtestclass='com.ibm.icu.dev.test.format.MeasureUnitTest'` | ||
| - Open the checkTest output: `out/junit-results/checkTest/html/index.html` | ||
| - Navigate to "System.out" at the bottom of the MeasureUnitTest page to find | ||
| the generated code, and copy to the clipboard. | ||
|
|
||
| After syncing CLDR data with ICU do the following. This documentation assumes | ||
| that you are updating the MeasureUnit clases for ICU 68. | ||
|
|
||
| * Check out | ||
| $GIT_ROOT/icu4j/main/common_tests/src/test/java/com/ibm/icu/dev/test/format/MeasureUnitTest.java | ||
| * Open MeasureUnitTest.java. | ||
| * Find the `testZZZ` test, its code should all be commented out. This test will | ||
| execute last and will run the desired code. | ||
|
|
||
| Make sure DRAFT_VERSIONS at top of MeasureUnitTest.java is set correctly. | ||
| These are the ICU versions that have draft methods. | ||
|
|
||
| ## Update MeasureUnit.java | ||
|
|
||
| * Change `testZZZ` to run `generateConstants(“68”); // ICU 68.` | ||
| * Run MeasureUnitTest.java, copy the generated code (see instructions above). | ||
| * Open MeasureUnit.java: | ||
| $GIT_ROOT/icu4j/main/core/src/main/java/com/ibm/icu/util/MeasureUnit.java | ||
| * Look for line containing: | ||
|
|
||
| `// Start generated MeasureUnit constants` | ||
| * Look for line containing: | ||
|
|
||
| `// End generated MeasureUnit constants` | ||
| * Replace all the generated code in between with the contents of the clipboard | ||
| * Run the MeasureUnitTest.java to ensure that the new code is backward | ||
| compatible. These compatibility tests are called something like | ||
| `TestCompatible65`, which tests backward compatibility with ICU 65. | ||
| * Create a compatibility test for ICU 68. Change `testZZZ` to run | ||
| `generateBackwardCompatibilityTest(“68”)` | ||
| * Run tests. | ||
| * Copy generated test (see instructions above) into MeasureUnitTest.java | ||
| * Run tests again to ensure that new code is backward compatible with itself | ||
|
|
||
| ## Update ICU4C | ||
|
|
||
| * checkout ICU4C | ||
|
|
||
| ### Update measunit.h | ||
|
|
||
| * Change testZZZ to run `generateCXXHConstants(“68”); // ICU 68`. | ||
| * Run MeasureUnitTest.java, copy the generated code (see instructions above). | ||
| * Open $GIT_ROOT/icu4c/source/i18n/unicode/measunit.h. Look for line containing: | ||
|
|
||
| `// Start generated createXXX methods` | ||
| * Look for line: | ||
|
|
||
| `// End generated createXXX methods` | ||
| * Replace all the generated code in between with the contents of the clipboard | ||
|
|
||
| ### Update measunit.cpp | ||
|
|
||
| * Change testZZZ to run generateCXXConstants(); | ||
| * Run MeasureUnitTest.java, copy the generated code (see instructions above). | ||
| * Open $GIT_ROOT/icu4c/source/i18n/measunit.cpp. Look for line containing: | ||
|
|
||
| `// Start generated code for measunit.cpp` | ||
| * Look for lines | ||
|
|
||
| `// End generated code for measunit.cpp` | ||
| * Replace all the generated code in between with the contents of the clipboard | ||
|
|
||
| ### Run C++ tests | ||
|
|
||
| * Run `./intltest format/MeasureFormatTest` from `test/intltest` to ensure new | ||
| code is backward compatible. | ||
| * Create a compatibility test for ICU 68. Change `testZZZ` in eclipse to run | ||
| `generateCXXBackwardCompatibilityTest(“68”)` | ||
| * Run tests. | ||
| * Copy generated test (see instructions above) into | ||
| $GIT_ROOT/icu4c/source/test/intltest/measfmttest.cpp. Make other necessary | ||
| changes to make test compile. You can find these changes by searching for | ||
| `TestCompatible65()` | ||
| * Run tests again to ensure that new code is backward compatible with itself | ||
|
|
||
| ## Finishing changes | ||
|
|
||
| These last changes are necessary to permanently record the ICU version number of | ||
| any new measure units. Without these changes any new functions for this release | ||
| will be considered new for the next release too. | ||
|
|
||
| * Change `testZZZ` to run `updateJAVAVersions(“68”);` | ||
| * Run MeasureUnitTest.java, copy the generated code (see instructions above). | ||
| * Append the clipboard contents to the values of the JAVA_VERSIONS variable | ||
| near the top of MeasureUnitTest.java. | ||
|
|
||
| **Important:** what you are copying are just the new functions for the current | ||
| ICU version, in this case 68. Therefore append, do not replace. | ||
|
|
||
| ## Updating units.txt and unitConstants | ||
|
|
||
| The standard ldml2icu process is used to update ICU's resource files (see | ||
| [cldr-icu-readme.txt](https://github.com/unicode-org/icu/blob/main/icu4c/source/data/cldr-icu-readme.txt)). | ||
| CLDR's units.xml defines conversion rates in terms of some constants defined in | ||
| `unitConstants`. | ||
|
|
||
| For efficiency and simplicity, ICU does not read `unitConstants` from the | ||
| resource file. If any new constants are added, some code changes would be | ||
| needed. This would be caught by `testUnitConstantFreshness` unit test in | ||
| `units_test.cpp`. | ||
|
|
||
| They are hard-coded: | ||
| * Java: `UnitConverter.java` has the constant names in | ||
| `UnitConverter.Factor.addEntity()` and constant values in | ||
| `UnitConverter.Factor.getConversionRate()`. | ||
| * C++: `units_converter.cpp` has the constant names in | ||
| `addSingleFactorConstant()`, with the constant values in `double | ||
| constantsValues[]` in the `units_converter.h` header file. |
