[alex40724]

See also #10862

Assessment:

Phiki is a syntax highlighter written in PHP. It uses TextMate grammar files and Visual Studio Code themes to generate syntax highlighted code for the web.

General Information:

• Name of the dependency: phiki/phiki
• Version: 2.0.5
• this dependency was already used in ILIAS.
• the dependency's license is compatible with ILIAS' license: MIT

Type of dependency:

• composer
• npm

Usage:

• components/ILIAS/COPage

Reasoning:

We abandonded the previous geshi library due to lacking maintenance. The syntax highlighter is being used in the page editor for code paragraphs. Having a syntax highlighter greatly improves readability of code snippets fostering teaching and learning of programming languages.

Maintenance:

• Last release of the Library: 2025-11-04
• One main developer, 11 contributors
• Monthly releases since Oct 2024
