Line numbers for rtf output

[Anteru]

(Original issue 1513 created by jonascj on 2019-05-06T12:56:56.977289+00:00)

I suggest to add a crude line numbering option to the RTF formatter available in pygments/pygmentize

Basically, after the rtf output is generated numbers padded with spaces could be added to the rtf document, in front of every line of highlighted code.

{ 2 } and {10 } serves very well as line numbers if put in front of every line of highlighted code (with a monospaced font of course). A script to do this is easily crafted, but it would be nice to add it to the RTF formatter. See the attached RTF-document as an example of my suggestion.

The only downside is that the code is not copy friendly in the final document (i.e. you will copy the line numbers as well), but who copies code from RTF/Word/LibreOffice documents anyway? My use case is students who do not write reports using LaTeX. This formatting option would make it easy to generate nice looking code snippets to paste into their reports (without resorting to taking screenshots).

I might get round to looking at submitting a patch during the summer, but maybe someone else will be hooked by this. In any case, now it is here for reference.

I’ve made a patch / changes to `pygments-main/pygments/formatters/rtf.py` which implements this.
Do I need permission to submit a PR?

Never mind, I found the way to make a pull request. As per [1] you have to click the “Create pull request”-button from within your own fork of the project, if you do not have write access to the project you wish to make a pull request to.

So I’ll just polish the patch a bit and learn basic hg, then submit the PR.

Any progress?

Not that I'm aware of, sorry.

@jonascj ping :)

I made something back then which could produce outputs such as the following (as rtf):

I remember almost submitting the patch but then discovering something (during testing) which stopped me doing so. Some cases which would fail, maybe lines that wrap (one line in the source code, but two lines in the highlighted rtf document) or maybe a problem with justifications of linenumbers above 9.

I'll see what I can find and submit it here, at least as a patch for discussion.
