What's broken?

Colors won't work for cmdrunner when using nodejs chalk or colorette library

See this issue for more details on why this is: #577

I tried giving FORCE_COLOR=1 as env variable but it seems chalk and colorette both failed to give NC character after they had it coloured. It'll be great if this is supported from cmdrunner instead. As both the libraries detects no support for color but on the other hand if I check for iTerm.app it seems to detect 256-bit color support for my current configuration.

@abhayjatindoshi Can you give more details on how you are using this? I.e. what is your config?

Have you tried wrapping this in a shell script and setting FORCE_COLOR=1 in that? CmdRunner probably doesn't use any environment variables passed to wtf

[abhayjatindoshi]

I tried to run the node script wrapped in a shell file as below.

# ~/temp.sh
export FORCE_COLOR=1
node ~/folder-path/index.js arguments

When I execute temp.sh on iTerm.app it gives the expected output.

Even on Terminal.app it works well like below

But when I execute that file on wtfutil as I said before the NOCOLOR char doesn't work. so even the :: are getting coloured like below.

This is my configuration on config.yml for cmdrunner

    cmdrunner_web:
      type: 'cmdrunner'
      title: '⬆️ ⬇️'
      cmd: 'sh'
      args: ["/Users/mac-name/temp.sh"]
      enabled: true
      position: 
        top: 1
        left: 0
        height: 1
        width: 1
      refreshInterval: 5

Thanks for the additional info! That is very interesting. Can you run echo $TERM, both on a base terminal AND as part of the shell script? I imagine it is consistent and reasonable, but want to make sure I can mirror your env as exact as possible here.'

Also, can you share more of the program you are testing with?

[abhayjatindoshi]

I've made up a small zip for you. It contains 3 files.

1. main.sh - shell file that you can use in cmdrunner
2. color.js - node js file which runs prints colored text using chalk library
3. color.sh - shell fille that prints the colored text using echo

Setting up is simple. unzip to your home folder and run either sh ~/temp/main.sh file or cd ~/temp; npm install

When you run the main.sh you'll see that color is set also for "color" word in node chalk case when you run on cmdrunner. The same if executed in a shell it shows word "color" without any color.

I THINK this is a bug in tview and potentially in chaulk.

Note that the 2 scripts are not actually working the same. The shell script is clearing the style, and chaulk is setting the foreground color to the default (white)

So chaulk is NOT clearing styles, so much as setting the default color. Tview doesn't handle default color, which I'll open a PR for.
