Fallback to all types if the selected types aren't present

[aarondill]

Summary 💡

Ideally, I'd like to use the default -T, but if there are no matches, instead of displaying no image and no Languages, I'd like to fall back to -T programming markup prose data.

Alternative: use onefetch -o json and jq to run onefetch once to detect if there's no LanguagesInfo.languagesWithPercentage, then regenerate onefetch output with the right argument. This requires running onefetch twice and parsing the output 😔

Motivation 🔦

I'd like to use the default -T programming markup most of the time, but I have some repos that have meaningful files (like docker compose.yaml) but no programming languages.

  local types=(programming markup)
  [ -n "$(onefetch -o json | jq '.infoFields[].LanguagesInfo.languagesWithPercentage | select(.)')" ] || types=(programming markup prose data)
  onefetch --no-color-palette --nerd-fonts -T "${types[@]}" -- "$current_repository"

This workaround works for me, but it would be nice not to have to run onefetch twice every time.

This has caused enough confusion that I think we should do something, and this is probably the best way to handle it. However, we do lose the chance to optimize a bit. AFAICT the only ways to handle this is to either sum up languages that we may not display or do a second pass over the repo if the original sum is 0.
