Make sure to end up with the same syntax highlighting inside various sections of diffs by processing the code first before detecting specific changes between the lines. Also try and make sure that when highlighting individual lines in a diff that it is tokenized the same as it would be when part of an entire file with more context.
Fixes: #12190
* Make copy/paste work for source code
Fix regression casued by #12047 so copy/paste works properly in all browsers.
Fixes#12184
Also while looking at this I saw a small display issue for blame view. I think #12023 was merged into original PR through an update branch before #12047 was merged and made one of the css ruules not apply anymore.
* use pseudo-element to prevent copying of comment + symbol even when not visually selected
* remove added newline here should not be necessary anymore
* make sure empty line is newline so there is something to select and copy
* Remove newline when highlighting random chunks of code
Somewhere when tokenizing a newline gets added to code formatted by chroma. This breaks the case of 'added-code' inside of an 'added-line' in a diff. Just remove any newline when processing chunks of code since we don't need it.
Fixes#12172
* don't process empty lines
* This is the proper way to fix this by telling chroma not to add the newline in the first place
* 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#7729Fixes#10157Fixes#11825Fixes#7728Fixes#3872Fixes#3682
And perhaps gets closer to #9553
