🔗 Langpacks-core for i18n functionality
🔗 Summary
Add langpacks-core-*
subpackages to langpacks
for easier installation of minimal core i18n support for a language
(locale, default font, and any default input-method if needed).

🔗 Current status
- Targeted release: Fedora 31
- Last updated: 2019-07-22
- Tracker bug: #1732123
- Release notes tracker: #365
🔗 Detailed Description
In Fedora 30 we replaced the remaining Yum language-support groups in Comps by extending the langpacks
meta packages to handle the installation of fonts (and input-methods) required for a language, in addition to locale and translation package weak dependencies.
However this all or nothing approach can be too heavy for some use cases, since the old language-support groups did not pull in translation langpacks.
With this Change we want to refine the approach to allow finer-grained installation of language support.
So users who only want basic support installed for a language (without translation langpacks and additional fonts for example)
can install langpacks-core-XY
to get just the default font, locale(s) and a weak dependency for any default input method.
Note: in this proposal XY
stands just for the ISO language code (eg es
for Spanish).
Users who want general default Fedora international support should continue to install @fonts
, @input-methods
, and
glibc-all-langpacks
(as they are already in Fedora Workstation, etc).
Later we may consider whether to separate the input methods into separate meta langpacks subpackages.
🔗 Benefit to Fedora
This allows more flexibility for users who want to do custom installations/Spins, or starting from minimal images/installs. They will be able to add basic i18n support for one or more specific language in a predictable standard way without pulling in additional langpacks for translations and extra fonts which may not be required for each added languages.
Users wanting full support for a language can continue to install the langpacks-XY
package for their language.
🔗 Scope
- Proposal owners:
- Add
langpacks-core-*
subpackages to langpacks for core i18n functionality:- default font
- glibc locale
- weak dependency on ibus IME if needed
- Other langpacks weak deps and additional fonts will remain in
langpacks-XY
. langpacks-XY
will requirelangpacks-core-XY
.- glibc locales subpackages weak dependencies will be updated to depend on
langpacks-core-XY
- Add
- Other developers: No other changes should be needed - current package translation langpacks will continue to depend on
langpacks-xx
.
- Release engineering: #8507
- Policies and guidelines: No major changes here
- Trademark approval: N/A (not needed for this Change)
🔗 Upgrade/compatibility impact
No impact - the design is fully backwards compatible: langpacks-XY
will pull in the new langpacks-core-XY
.
🔗 How To Test
This Change implementation is available for testing using copr repo.
- dnf list langpacks-*
- dnf install langpacks-core-XY
- dnf install langpacks-XY
🔗 User Experience
Fedora users will have more flexibility with installation of i18n support packages and langpacks.
🔗 Dependencies
glibc.spec needs to be updated with s/langpacks/langpacks-core/
once langpacks
has implemented langpacks-core
.
No other packages should be directly affected by the current proposal.
🔗 Contingency Plan
- Contingency mechanism: Proposal owners will revert to F30
langpacks
and glibc - Contingency deadline: Beta freeze
- Blocks release? No
- Blocks product? N/A
🔗 Documentation
No additional documentation at this stage.
