Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/1839

Originally assigned to: @NghiaTranUIT on GitHub.

Description

In my case, I have some variables with fixed keys, but their values change frequently. Previously, I manually opened the script and wrote the new values, but it became tedious. So, I tried writing the variables to the ~/.zshrc file and changed the ENV in ~/.zshrc quickly. However, I found that Proxyman couldn't read the latest variables.

Is it possible to provide a hook for Proxyman to get the latest environment variables? Or, can Proxyman support a feature to save simple variables and let me choose one from the menu bar quickly?

Thank you!

Why this feature/change is important?

Proxyman is a very professional and easy-to-use tool. Adding such a feature doesn't feel very complicated, but it would provide higher customization options for professional users.

Proxyman Scripting can read your ENV from ~/.zshrc (docs).

Here is the example:

async function onResponse(context, url, request, response) {
  console.log($PATH);
  console.log($ACCESS_TOKEN);
  console.log($PROXYMAN_PATH);
 
  // Done
  return response;
}

@NghiaTranUIT commented on GitHub (Nov 5, 2023): Proxyman Scripting can read your ENV from `~/.zshrc` ([docs](https://docs.proxyman.io/scripting/environment-variables#2.-environment-variables)). Here is the example: ```js async function onResponse(context, url, request, response) { console.log($PATH); console.log($ACCESS_TOKEN); console.log($PROXYMAN_PATH); // Done return response; } ```

Thank you for your reply!

I am able to use the ENV from ~/.zshrc, and I find that the Proxyman documentation is very comprehensive. However, my problem is whether Proxyman can automatically read the updated from ~/.zshrc ?

It's not automatically load the env yet because it's an expensive operation. That's the reason why I introduced the "Reload env" button.

How often your ENV is changed that you need to reload the ENV automatically?

Actually, The frequency of changes actually depends on how busy I am at the moment. I am working on multiple projects simultaneously, and each project has a fixed key. However, the value that determines the flow direction for each project is different. That's why I want to have a 'Quick Switch and Reload' feature. I usually do it manually，which is why I would like to have a hook to inform Proxyman to reload the ENV ？

By the way, I fully understand that automatically loading environment variables is also an expensive operation. Therefore, I'm wondering if it's possible to provide a hook or API for me to call?

I guess I can introduce a helper func, like:

_reloadENV();

It runs synchronously and you can run it directly in your Scripts. How do you feel?

Does this mean I have to call it within a script in Proxyman? Can I have my own program call it instead? Some external applications or shell scripts that I developed myself. If this is very difficult, then calling it within a Proxyman script is also good, at least I can use it.
