Description

Hi all,

GitLab uses Monaco/Monarch to highlight files/snippets and GitLab is now the official Scilab (https://www.scilab.org/) development platform. Having this feature would simplify the reading of Scilab code in repository, issues, wiki, ...

Here are some links to other implementations:

• Pygments: https://pygments.org/docs/lexers/#pygments.lexers.matlab.ScilabLexer
• Chroma: https://github.com/alecthomas/chroma/blob/master/lexers/embedded/scilab.xml
• Highlight: https://github.com/highlightjs/highlight.js/blob/main/src/languages/scilab.js

Thanks.
