coerl

cörl colourises curl's output.

Usage

Use coerl instead of curl. curl is still required.

$ COERL_SSL_DATA_OFF=0 coerl -vs -d '{}'
$ COERL_TEXT_OFF=1 COERL_SSL_DATA_OFF=1 coerl --compressed -sv 'https://api.spotify.com/v1/search' | jq .

$ alias curl=coerl
$ curl -sv -L https://google.com > /dev/null
$ COERL_DATA_OFF=1 COERL_TEXT_OFF=1 curl -sv -L https://google.com > /dev/null

Installation

$ go get -u github.com/op/coerl

Knobs

Background

Short version:

-v has too much data
-I writes to stdout and breaks piping
colours can help

curl together with its (verbose) output is great in many ways. The --include flag includes the HTTP-header in the output. However this breaks piping of the output, to eg. jq or rq, since headers are written to stdout. Using the --verbose flag fixes this but also introduces heaps of output.

This hack adds some colours to the --verbose output of curl.

Credit goes to httpstat for inspiration.

Limitations

Guessing is done to determine if the data is for SSL or not.
