I'm a Vim user trying to learn Spacemacs. In Vim, I execute a Scheme program by typing :mit-scheme < xxx.scm. After the program exits, I can continue editing simply by press Enter.

However, doing this in Spacemacs (in evil mode, of course) would create a new buffer, which I have to kill manually by typing three characters: <space> b d. This is quite inconvenient for me, because I'm a inexperienced programmer who needs to execute programs very frequently while debugging.

How to make execute a program more efficiently in Spacemacs? For example, I want close the output window/buffer in one keystroke. I'm also glad to know if I can replace :mit-scheme < xxx.scm with some key bindings.

  • For scheme I think you could use something like Geiser nongnu.org/geiser which should help you do things much easier.

  • @caisah Seem that Geiser is shipped with the Scheme layer. However, when I try to use those key bindings, a SPC m is undefined error is thrown.

  • @caisah I've installed the Scheme layer successfully! However, it only prints out the value of the last expression, while I want to see the value of every expression in a .scm file, just like what happens when I feed the whole file to a REPL.

I've got an workaround: open an terminal in Emacs with the Shell layer. After installing the Shell layer, you can toggle a shell window using SPC '​.

You can execute mit-scheme < xxx.scm in that terminal, which seems more convenient to me than using the Scheme layer
