On my site,
- codemirrors are read-only, not used for editing
- Line numbers where languages start and finish are known
- For example, PHP & Typescript in one editor
- Using a separate codemirror for each language is possible, but I just wanted to explore putting all code in one codemirror.
following the examples CodeMirror Mixed-Language Parsing Example seems like it would take me many hours to get it working, so if no one has any ideas I think I would just use multiple codemirror instances instead.
If I had like 10 codemirros on one page, would that be a performance issue?
