How to display line numbers with pygmentize

rated 0 times [ 3] [ 0] / answers: 1 / hits: 2245 / 3 Years ago, tue, july 27, 2021, 10:05:27

I often use the command pygmentize filename.py to show color source files with code formatting. This works like a charm. I now also want to show line numbers like cat -n filename.py does.

I read around and found some suggestions like adding -O linenos=1 or -O linenos=True. None of this seems to work though.

Does anybody have any idea how I can show line numbers when viewing source files on the command line with pygments? All tips are welcome!

You can add line numbers using perl like this:

pygmentize file.py | perl -e 'print ++$i." $_" for <>'

Update (to alias the previous command):

To create an alias, just define the following bash function somewhere in your ~/.bashrc:

pyg() {

pygmentize $1 | perl -e 'print ++$i." $_" for <>'

}

Open a new terminal and call the command with pyg file.py.
