If you are new to Emacs, you may run into some errors, especially after you copied some elisp snippets from the Internet or elsewhere. Don't panic! It happens, it's just part of the learning process. Even an experienced Emacs user could run into there issues from time to time.

BTW, I'm improving my English by watching YouTube videos every single day; If you're also learning English, or any languages, LanguagePuppy can definitely help you. It's a Chrome extension I developed using Clojure. Check it out:

There are many packages of Emacs that leverage subprocesses to do their jobs, Magit, eglot, elpy, to name a few. And there are times that a subprocess doesn't work as expected, for example, Magit is slow, and you're sure that it's ok when running git commands on shell. So how to spot these problems effectively and quickly?

The problem is that we don't know what's going on exactly, so here I want to share a few Elisp advices to make the subprocess creating visible, and print the exact program and its arguments to the *Message* buffer. Visibility is the key.
