Emacs Tricks With Go

I am still going through some Go tutorials. I am using Emacs as my editor.

There are some things that the go mode does not handle well; I don’t know if this is a shortcoming in the mode, or if I am using an old version, or if there is some conflict with another mode I am using. It’s actually a minor point.

It does not indent switch statements the way I want. All the “case” statements and everything inside them is indented as far as the “switch”. Hitting tab does not work. I have to hit “space” for every line. It gets pretty tedious.

But I found a way to do it:

  • set-mark-command (C-@) and highlight the region
  • indent-rigidly (C-x TAB)
  • hit the arrow key as many times as I need. This will indent all the lines the same amount.

 

I also learned something about opening files. I had a directory with a file called “time.go” and “showtime.go”. When I tried find-file (C-x C-f), or switch-to-buffer (C-x b), it kept picking up “showtime.go”, even though I wanted “time.go”. I was able to open “time.go” with find-alternate-file (C-x C-v). Then I had to re-open “showtime.go”. It’s not a perfect solution, but it worked for me.

These commands are not unique to the Go mode.

You’re welcome.
