1 # Language Tags
3 Code for language tags, LanguageTag wrapper for liblangtag and converter between BCP47 language tags, Locale(Language,Country,Variant) and MS-LangIDs.
5 Basic functionality used by almost every other module including comphelper, so even don't use that string helpers in this code to not create circular dependencies. Stick with sal and rtl!
9 If Microsoft introduced a new LCID for a locale that we previously defined as `LANGUAGE_USER_...`, for example `LANGUAGE_CATALAN_VALENCIAN` that we had as `LANGUAGE_USER_CATALAN_VALENCIAN`:
11 * `include/i18nlangtag/lang.h`
12     * add the new `LANGUAGE_...` value as defined by MS, here `LANGUAGE_CATALAN_VALENCIAN`
13     * rename the `LANGUAGE_USER_...` definition to `LANGUAGE_OBSOLETE_USER_...`, here `LANGUAGE_USER_CATALAN_VALENCIAN` to `LANGUAGE_OBSOLETE_USER_CATALAN_VALENCIAN`
14     * add a `#define LANGUAGE_USER_CATALAN_VALENCIAN LANGUAGE_CATALAN_VALENCIAN`
15         * so `svtools/source/misc/langtab.src` (where the defined name is an identifier) and other places using `LANGUAGE_USER_CATALAN_VALENCIAN` do not need to be changed
17 * `i18nlangtag/source/isolang/isolang.cxx`
18     * insert a mapping with `LANGUAGE_CATALAN_VALENCIAN` before (!) the existing `LANGUAGE_USER_CATALAN_VALENCIAN`
19     * rename the `LANGUAGE_USER_CATALAN_VALENCIAN` to `LANGUAGE_OBSOLETE_USER_CATALAN_VALENCIAN`
20         * so converting the tag maps to the new `LANGUAGE_CATALAN_VALENCIAN` and converting the old `LANGUAGE_OBSOLETE_USER_CATALAN_VALENCIAN` still maps to the tag.
22 * `i18nlangtag/source/isolang/mslangid.cxx`
23     * add an entry to `MsLangId::getReplacementForObsoleteLanguage()` to convert `LANGUAGE_OBSOLETE_USER_CATALAN_VALENCIAN` to `LANGUAGE_CATALAN_VALENCIAN`
26 When changing a (translation's) language tag (for example, `ca-XV` to `ca-valencia` or `sh` to `sr-Latn`):
28 * `solenv/inc/langlist.mk`
29     * replace the tag and sort alphabetically
31 * in `translations/source` do  `git mv old-tag new-tag`
32     * note that translations is a git submodule so <https://wiki.documentfoundation.org/Development/Submodules applies>
34 * `i18nlangtag/source/isolang/isolang.cxx`
35     * maintain the old tag's mapping entry in `aImplIsoLangEntries` to be able to read existing documents using that code
36     * add the new tag's mapping to `aImplBcp47CountryEntries` or `aImplIsoLangScriptEntries`
37     * change `mnOverride` from 0 to `kSAME` in `aImplIsoLangScriptEntries` or `aImplIsoLangEntries`
39 * `i18nlangtag/source/languagetag/languagetag.cxx`
40     * add the new tag's fallback strings to the fallback of the old tag in `LanguageTag::getFallbackStrings()`
42 * `i18nlangtag/qa/cppunit/test_languagetag.cxx`
43     * add a unit test for the new tag and old tag
45 * `l10ntools/source/ulfconv/msi-encodinglist.txt`
46     * replace the tag and sort alphabetically
48 * `setup_native/source/packinfo/spellchecker_selection.txt`
49     * replace the tag and sort alphabetically
51 If locale data exists:
53 * `i18npool/source/localedata/data/*.xml` for example `i18npool/source/localedata/data/sh_RS.xml`
54     * in the `<LC_INFO>` element
55         * change `<LangID>` to `qlt`
56         * after the `<Country>` element add a `<Variant>` element with the new full BCP 47 tag, for example `sr-Latn-RS`
57             * note that `<Variant>` has no `<VariantID>` or `<DefaultName>` child elements
58     * if any of the other `*.xml` files reference the locale in a `ref="..."` attribute, change those too; note that these references use '`_`' underscore instead of '`-`' hyphen just like the file names do
59     * rename `sh_RS.xml` to `sr_Latn_RS.xml`, `git mv sh_RS.xml sr_Latn_RS.xml`
61 * `i18npool/source/localedata/localedata.cxx`
62     * in `aLibTable` change the entry from old `sh_RS` to new `sr_Latn_RS`, do not sort the table
64 * `i18npool/Library_localedata_*.mk`     for example `i18npool/Library_localedata_euro.mk`
65     * change the entry for the changed `.xml` file, for example `CustomTarget/i18npool/localedata/localedata_sh_RS` to `CustomTarget/i18npool/localedata/localedata_sr_Latn_RS`, sort the list alphabetically
67 If dictionary exists:
69 * `dictionaries/*/dictionaries.xcu`      for example `dictionaries/sr/dictionaries.xcu`
70     * change the affected `<node oor:name="...">` elements to something corresponding, for example `<node oor:name="HunSpellDic_sh" ...>` to `<node oor:name="HunSpellDic_sr_Latn" ...>`
71     * in the `Locales` properties change the `<value>` element, for example `<value>sh-RS</value>` to `<value>sr-Latn-RS</value>`
73 If dictionary is to be renamed, for example `ku-TR` to `kmr-Latn`:
75 * `dictionaries/*/*`                     for example `dictionaries/ku_TR/*`
76     * if appropriate rename `*.dic` and `*.aff` files, for example `ku_TR.dic` to `kmr_Latn.dic` and `ku_TR.aff` to `kmr_Latn.aff`
77 * `dictionaries/Dictionary_*.mk`         for example `dictionaries/Dictionary_ku_TR.mk`
78     * rename file, for example to `Dictionary_kmr_Latn.mk`
79     * change all locale dependent file names and target, for example `ku_TR` to `kmr_Latn` AND `ku-TR` to `kmr-Latn`; note '`-`' and '`_`' separators, both are used!
