cmd runner not working as expected

[GideonWolfe]

What's broken?

I have tried a couple times to incorporate commands I run in the terminal to cmdrunner widgets without success.

1. First example, iponmap. iponmap takes a list of IP addresses and displays them on a map in the terminal.

I have a script that goes

curl -s 'http://some.site/api...' | jq 'some json parsing' | iponmap

When I try to run this script from a cmdrunner widget, the widget is simply blank, no errors or anything.

2. ghcal prints a text representation of your github contributions into the terminal. When I run ghcal --no-ansi in my shell, I get

But when I try to run this command in a wtf cmdrunner, the window just says "exit status 1", which I have never gotten from just running the command.

Here is how I am trying to launch it

Without seeing your shell script I can't know what's going on there, but with the ghcal example, that also fails in this very simple version: https://gist.github.com/senorprogrammer/5ae02f3bd39ab4bd5e3415cfc1802c6c

Something about ghcal isn't playing nicely with how commands are executed in Go. In that example gist, using ls works just fine.

Here is the entirety of my script

#!/bin/bash
curl -s "http://jellyfin.domain/Sessions?api_key=API_KEY" | jq -r '.[] | .RemoteEndPoint' | iponmap

Which essentially pipes a list of IPs

192.364.3.65
546.767.45.3
23.545.6.45

to iponmap. (these are random IP, they don't work)

[Seanstoppable]

iponmap seems to be due to the library used to render it.
https://github.com/chjj/blessed is an widget api, of which programs can be interactive.
Just using the hello world example from the repo, I get the same behavior.
You'll notice that on quitting, you drop back into your terminal as is, so it doesn't look like it is exporting content such that another app can grab it, like other scripts which are spitting out data to the terminal.

[GideonWolfe]

Ah, unfortunate in both cases then. Thanks for looking into it guys!

[senorprogrammer]

Thanks for that info @Seanstoppable, that's extremely helpful. And you're welcome @GideonWolfe , should you have any other issues, don't hesitate to ask. You bringing this up has shown me that I should provide some documentation on possible limitations of the command runner.

Adding to this issue for posterity. Recently got "exit status 2" from using CmdRunner to run a Python script which prints to std out no problem when ran in terminal. I initially specified the file path relative to home dir using "~", changing to absolute file path got it to work.
