Gum Spin option to print output while executing command ?

[aravind-kumar]

Hi

Started using gum for my shell scripts, it's pretty cool and easy to use. 😄

I was wondering if theres a way to print the output while the command is run as opposed to after completion.

The command takes a few minutes to complete and the user can only see the spinner .

I would like to also show the output of the command while spinner is spinning , to show progress.

Today when i use --show-output option i see can see the whole output after completion of the command.
I looked at the code : link

we seem to print the output after executing the command.

I was wondering if theres a way i could have the spinner be fixed running at the top (Like a header) while the output of command is filled below as the command is run.

I tried to play with the input command :

• I tried to redirect the stdout and err as part of input command with "2>&1"
• I tried to rediect the output to terminal with | tee /dev/stdout
• The closest i could get to achieving the behaviour was passing a sleep command to spin and running the actual command in parallel
  • With this approach i could get the output while the spinner was running for pre-determined sleep time
  • But this had its own set of issues like when the actual command failed and the spinner kept running
  • I couldnt control the spin time and the spinner kept spinning at the bottom of the screen while the output of command filled top
