go-vl

go-vl provides vl filter to make CUI table vertical.

Usage

For example, this is output of kubectl get pods.

$ kubectl get pods
NAME                         READY     STATUS    RESTARTS   AGE
hello-web-4017757401-ntgdb   1/1       Running   0          9s
hello-web-4017757401-pc4j9   1/1       Running   0          9s

The vl filter makes it vertical like below.

$ kubectl get pods | vl
********** 1 ********************
    NAME: hello-web-4017757401-ntgdb
   READY: 1/1
  STATUS: Running
RESTARTS: 0
     AGE: 9s
********** 2 ********************
    NAME: hello-web-4017757401-pc4j9
   READY: 1/1
  STATUS: Running
RESTARTS: 0
     AGE: 9s

--grep option works.

$ kubectl get pods | vl --grep pc4j9
********** 1 **********
    NAME: hello-web-4017757401-pc4j9
   READY: 1/1
  STATUS: Running
RESTARTS: 0
     AGE: 9s

And --ps flag to parse lines separated by only 1 space between columns.

$ ps
  PID TTY          TIME CMD
12523 pts/4    00:00:00 bash
30087 pts/4    00:00:00 ps

$ ps | vl --ps
********** 1 **********
 PID: 12523
 TTY: pts/4
TIME: 00:00:00
 CMD: bash
********** 2 **********
 PID: 30087
 TTY: pts/4
TIME: 00:00:00
 CMD: ps
