Hi @ocervell, it should also work with that kind of complex expressions.
In any case your expression seems to be a good test case, could you please paste a text version of it? I would like to included in the test suite and fix the output.

Thanks for report it 👍

I confirm there's a bug, I was able see it using this fragment of your expression:

(sum(rate(metric_test_app{app="turtle",proc="web"}[2m])) by(node))

and I opened a pull request to fix it.

Here's an example of the output before:

and after the fix from #5:

note: those example were generated using

pygmentize -f png -O "line_numbers=False,style=monokai" -o example.png example.promql

I'll wait for your full text PromQL expression to test it before merging this fix.

Hi @pabluk,

Thanks for the swift response !

Here is the full expression:

(sum(rate(metric_test_app{app='turtle',proc='web',vendor=~'vendor.',status=~'(4|5)..'}[2m])) by(node)) or (sum(rate(metric_test_app{app='turtle',proc='web',vendor=~'vendor.'}[2m])) by(node)-sum(rate(metric_test_app{app='turtle',proc='web',vendor=~'vendor.',status!~'(4|5)..'}[2m])) by(node))/sum(rate(metric_test_app{app='turtle',proc='web',vendor=~'vendor.',status!~'(4|5)..'}[2m])) by(node)*100",

Great! the output of the full expression looks better now

by the way, your full expression allowed me to find out and fix a typo on a regexp.

I'll merge the PR and publish a new release asap.

Thanks again for helping out to improve this PromQL lexer!

The new release 0.0.6 is now available on PyPI https://pypi.org/project/pygments-promql/

Perfect ! Thanks a lot :)
