* Server-side syntax hilighting for all code This PR does a few things: * Remove all traces of highlight.js * Use chroma library to provide fast syntax hilighting directly on the server * Provide syntax hilighting for diffs * Re-style both unified and split diffs views * Add custom syntax hilighting styling for both regular and arc-green Fixes #7729 Fixes #10157 Fixes #11825 Fixes #7728 Fixes #3872 Fixes #3682 And perhaps gets closer to #9553 * fix line marker * fix repo search * Fix single line select * properly load settings * npm uninstall highlight.js * review suggestion * code review * forgot to call function * fix test * Apply suggestions from code review suggestions from @silverwind thanks Co-authored-by: silverwind <me@silverwind.io> * code review * copy/paste error * Use const for highlight size limit * Update web_src/less/_repository.less Co-authored-by: Lauris BH <lauris@nix.lv> * update size limit to 1MB and other styling tweaks * fix highlighting for certain diff sections * fix test * add worker back as suggested Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: Lauris BH <lauris@nix.lv>
