Add to $PATH

[rejeep]

Hi,

I'm trying to create an async job that runs the mocha command, which is a node-js file with this shebang #!/usr/bin/env node. The problem is that node lives in /usr/local/bin and that is not in Emacs default path.

I'm trying to add that to the path using this:

(let ((default-directory "/Users/user/")
      (exec-path (cons "/usr/local/bin/" exec-path)))
  (async-start-process
   "path"
   "/Users/user/echo_path.sh"
   (lambda (process)
     (with-current-buffer (process-buffer process)
       (print (buffer-string))))))

But the path is not added. I can use setenv, but that will set it for good, which I don't want. Sure I could use setenv again and restore the value, but that seems rather lame. Any way to only set the path while running the async job?

Is this perhaps related to #13?

Related, yes. But not the same issue. In order to do what I want, I need to:

• Be in the correct folder (https://github.com/jwiegley/emacs-async/issues/13 solves this)
• Have node in my path when I exec the mocha command. This is what this issue is about.

Setting exec-path is not the good approach because it will not affect you PATH in the view of your script, try instead modifying your PATH inside your script.
