Jqfmt like gofmt, but for jq

Summary

Description I'm frequently passed long shell one-liners that require some visual inspection before running. These days, there's about as much jq in that one-liner as there is bash. I wrote jqfmt to help add line breaks in sensible locations while reading (or writing!) jq. At time of initial development, I naturally turned to https://github.com/itchyny/gojq expecting to be able to generate and walk a syntax tree—but gojq didn't seem to provide an AST that could be "walked," and it doesn't export its parsing logic to be used in library form. So, I yanked the relevant code out of https://github.com/itchyny/gojq/blob/main/query.go and started from there. Side note: Ever tried Googling for "jq formatter"? Reading search results is a nightmare since jq itself is, among other things, a formatter. Getting started Install go install -v github.com/noperator/jqfmt/cmd/jqfmt@latest Usage 𝄢 jqfmt -h Usage of jqfmt: -ar arrays -f string file -o one line -ob objects -op string operators -v verbose Let's take this line of jq… 𝄢 echo '{one: .two, three: [.four, .five, [.fivetwo, .fivethree]], six: map(select((.seven | .eight | .nine)))}' | jqfmt { one: .two, three: [.four, .five, [.fivetwo, .fivethree]], six: map(select((.seven | .eight | .nine))) } …and format objects. 𝄢 echo '{one: .two, three: [.four, .five, [.fivetwo, .fivethree]], six: map(select((.seven | .eight | .nine)))}' | jqfmt -ob { one: .two, three: [.four, .five, [.fivetwo, .fivethree]], six: map(select((.seven | .eight | .nine))) } Nice! Let's also do arrays. 𝄢 echo '{one: .two, three: [.four, .five, [.fivetwo, .fivethree]], six: map(select((.seven | .eight | .nine)))}' | jqfmt -ob -ar { one: .two, three: [ .four, .five, [ .fivetwo, .fivethree ] ], six: map(select((.seven | .eight | .nine))) } It'll read easier if we also break on pipes. 𝄢 echo '{one: .two, three: [.four, .five, [.fivetwo, .fivethree]], six: map(select((.seven | .eight | .nine)))}' | jqfmt -ob -ar -op pipe { one: .two, three: [ .four, .five, [ .fivetw...
