oarepo-theme 4.0.0

SemanticUI Invenio app theme overlay for NRP repositories

OARepo Theme

SemanticUI theme overlay for InvenioRDM based NRP repositories.

Overview

This package provides a customized Semantic UI theme configuration for Invenio applications, specifically designed to integrate with OARepo repositories. It extends the default Invenio-App-RDM theme with custom styling capabilities and supports integration with multiple OARepo UI packages.

Installation

pip install oarepo-theme

Requirements

• Python 3.14+
• InvenioRDM v14.x
• OARepo v14.x

Key Features

1. Webpack Theme Bundle Integration

Source: oarepo_theme/webpack.py

The package provides a WebpackThemeBundle that integrates with Invenio's asset management system.

Key capabilities:

• Webpack bundle configuration for Semantic UI assets
• Path aliases for Less/CSS customization
• Integration with Invenio's asset compilation pipeline
• Support for custom theme overrides

2. Theme Configuration

Source: oarepo_theme/assets/semantic-ui/less/theme.config

Centralized theme configuration that sets Semantic UI component themes:

/* Global */
@site        : 'rdm';
@reset       : 'default';

/* Elements */
@button      : 'rdm';
@container   : 'rdm';
@header      : 'rdm';
@input       : 'rdm';
@label       : 'rdm';
/* ... and more */

The configuration specifies which theme variant to use for each Semantic UI component, defaulting to the 'rdm' theme from Invenio-App-RDM.

3. Theme Override Order

Docs: https://nrp-cz.github.io/docs/customize/repository_ui/branding/theme#theme-hierarchy

Theme uses the SemanticUI theme layering system that supports multiple customization layers. Loading order (from lowest to highest priority):

1. Default Semantic UI theme
2. Invenio-theme
3. Invenio-App-RDM theme
4. OARepo package themes (oarepo_theme, oarepo_ui, oarepo_vocabularies_ui, etc.)
5. Site-specific overrides & custom component variables

Supported OARepo packages:

• oarepo_ui - Core UI components
• oarepo_vocabularies_ui - Vocabulary management UI
• oarepo_dashboard - Dashboard components
• oarepo_communities - Community features
• oarepo_requests_ui - Request workflow UI

Each package can provide:

• Component variables (.variables files)
• Style overrides (.overrides files)
• Custom SemanticUI (LESS) components

On top of that, site specific style customizations can be made.

4. Webpack Aliases

This theme bundle configures the following Webpack aliases for easy asset referencing:

Alias	Target	Purpose
../../theme.config$	less/theme.config	Main theme configuration file
../../less/site	less/site	Site-specific styles & overrides
../../less	less	Less source directory
@less	less	Less imports shorthand pointing to correct less sources
themes/oarepo	less/oarepo	OARepo theme directory

Development

Setup

# Clone repository
git clone https://github.com/oarepo/oarepo-theme.git
cd oarepo-theme

./run.sh venv

Running Tests

./run.sh test

Or run specific test file:

./run.sh test tests/test_webpack.py -s

The package includes tests that verify:

• Webpack alias configuration
• Theme bundle registration
• Asset directory paths
• Entry point loading

See tests/test_webpack.py for examples.

Usage in NRP repositories

Runtime usage

When you generate a new NRP repository based on InvenioRDM, the theme is automatically installed and registered for use via Invenio entry points

[project.entry-points."invenio_assets.webpack"]
oarepo_theme = "oarepo_theme.webpack:theme"

No additional configuration is needed - the theme will be available after installation.

Usage in tests

This theme package can be also used for front-end development & tests (Storybook), so that the tested UI shares the same styles as in the runtime.

When developing a UI-oriented library, include a dependency to your tests package extras:

#pyproject.toml
tests = [
    "pytest>=7.1.2",
    "oarepo-theme>=1.0.0dev1,<2.0.0",
    # ...
]

Then you can set-up Storybook tests to use this theme package:

./run.sh jstest setup --with-storybook

Customizing the Theme

To customize the theme in your application:

1. Override variables: Create files in your app's /assets/less/ directory:

   /* assets/less/globals/site.variables */
   @primaryColor: #2185d0;
   @linkColor: #4183c4;
   

2. Add custom styles: Create override files:

   /* assets/less/elements/button.overrides */
   .ui.button {
     border-radius: 4px;
   }
   

For more in-depth guide to theme customization, please refer to the official Theme Customization Docs.

Entry Points

The package registers the following Invenio entry point:

[project.entry-points."invenio_assets.webpack"]
oarepo_theme = "oarepo_theme.webpack:theme"

This entry point is automatically discovered by Invenio and makes the theme available to the asset compilation system.
