about

promfmt is a very naive PromQL formatter. One can pipe a promql query in it, and it gets formatted.

I really hope someone will create a proper formatter some day, but for now this one will have to do in my vimrc :).

Example

echo 'sum by (bla, bladiebla, woot) (rate(somemetric{labelx="asdfasdf",labely="jajanounou"}[5m])) * 1024' | ./promfmt

sum by (bla, bladiebla, woot) (
    rate(
      somemetric{labelx="asdfasdf",labely="jajanounou"}[5m]
    )
  )
*
  1024

or in .vimrc

augroup promql
  autocmd!
  autocmd FileType promql nmap <F3> :%!cat - \| promfmt<CR>
augroup END
