ccat

cat on steroids. Leveraging great go modules to ease my CLI life.

build

you need go >=1.15, available build tags:

• libcurl: build with the libcurl opener.
• fileonly: build with the local file opener only.
• nomd: build without the markdown interpreter (glamour).
• nohl: build without the syntax-highlighter.
• crappy: build with some crappy (but useful) openers/mutators (needs a recent go version).

for instance: go build --tags libcurl,crappy .

examples

cat -X "kubectl get all" -i -w -t ready,Running --bg
NAME           READY   STATUS    RESTARTS   AGE
pod/busybox3   1/1     Running   1          17m

service/kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   21d

( "READY and "Running" have different background colors )
