Add library override/extend file definitions

Open on Drupal.org →

Problem/Motivation

Many library override/extend definitions can create a very large theme.info file, making it slightly difficult to maintain.

Proposed resolution

Themes should check for an existing theme.libraries.override.yml or theme.libraries.extend.yml file. If either file exists, the definitions in the file are used instead of the definitions in theme.info.

Remaining tasks

Reviews need, tests need to be written and run, documentation needs to be added. Waiting on initial feedback before proceeding.

User interface changes

None.

API changes

Theme developers will be allowed to specify a theme.library.override.yml or theme.library.extend.yml file, eg:

Override

# bartik.libraries.override.yml
core/drupal.dropbutton:
    css:
      component:
        /core/themes/stable/css/core/dropbutton/dropbutton.css: css/components/core/dropbutton.css

Extend

# bartik.libraries.extend.yml
system/base:
    - bartik/system.base
