Hello,  
I want to run different python scripts from my Stream deck buttons and change the buttons appearance based the results.

I've defined a _Stream Deck Script Widget_ using JavaScript that calls a bash script that calls my python script....that's a lot of scripts in a row 😅 but I guess there is no other way, here's why:

**1 - Js Script:**

```javascript
(async () => {

  let pyScriptRelPath = './rel/path/to/script.py' // this path is relative from the `shellScriptAbsPath`
  let shellScriptAbsPath = `/abolute/path/to/execute.sh ${pyScriptRelPath}`; // absolute path to my shell script

  let shellScriptWrapper = {
      script: shellScriptAbsPath,
      launchPath: '/opt/homebrew/bin/bash', //my bash version
      parameters: '-c', 
      environmentVariables: ''
  };
  
  let result = await runShellScript(shellScriptWrapper);
  returnToBTT(result);
})();

```

JS calls a bash script, this script is a generic `execute.sh` to which I pass a relative path to the python scripts I want to execute, that is `pyScriptRelPath`.  
I do this because I'm planning to make this Js reusable and just pass this variable to it.

**QUESTION 1:** how to reuse this code?  
I've tried to do this with named trigger but there isn't any named trigger that resemble the **Stream Deck Script Widget** so I guess at the moment I can't do this and I would need to replicate this script in all my StreamDeck buttons that need to execute my scripts. Unless there is another solution.

**2 - Bash script**

```bash
#!/usr/bin/env bash
export PATH=$PATH:/usr/local/bin/;

# I do this to be able to execute my python from a relative path from where this file is located
parent_path=$( cd "$(dirname "${BASH_SOURCE[0]}")" ; pwd -P )
cd "$parent_path"

# path to my pyenv virtualenv python bin 
outputString=$("/my/pyenv/virtualenv/bin/python" ./$1)
echo $outputString 

exit;

```

This bash script:

- takes the relative path of my python script as input
- execute my python script using a specific virtualenv python version
- print the result (that will be the result passed to BTT)

**3 - Python Script**

```python

def main():
    print('{"text": "TEST", "BTTStreamDeckBackgroundColor": "100,100,100,255"}')

if __name__ == " __main__":
    main()

```

My python script print the escaped json that will be passed to bash and then to BTT to actually style the StreamDeck button.

**QUESTION 2**  
At the moment this works but given the Widget Option "Execute script every x seconds" the script is always executed at least once even if I put very big number.  
This will produce unwanted result in my workflow as I need the script to be executed EXACTLY once when and only when I push the button.  
I guess at the moment this isn't possible, isn't it?

In this case the widget functionality should be slightly modified to:

- allow for a default button appearance
- allow the script to be executed only when the button is pushed

Any other way to achieve these results (_question 1 and 2_) with the current limitations ?  
Also any way to simplify this workflow? That's a long line of scripts to be called 😅

Thanks
