muwrap
muwrap is a simple command-line utility for wrapping text.
Pipe text into muwrap, and it'll echo a wrapped version of that text. It
automatically handles comment characters.
$ cat >example
// This is an example of a long comment. Let me show you how to use muwrap to automatically wrap this comment into multiple lines.
$ muwrap <example
// This is an example of a long comment. Let me show you how to use muwrap to
// automatically wrap this comment into multiple lines.
Installation
If you're using Arch Linux, you can install muwrap-git from the AUR, for example using yay:
$ yay -S muwrap-git
Otherwise, see Building below.
Building
muwrap is written in Nim. Install Nim, and then run this command to compile it:
$ nim compile main.nim
This will create the main executable. You should put this somewhere in your
path. For example, if you have ~/bin/ in your path, run:
$ mv main ~/bin/muwrap
Kakoune
I use this with Kakoune. Just select some text, and then
type |muwrap<ret> to replace it with the wrapped version, assuming you have
muwrap in your path. You can bind it to ,w with this line in your kakrc:
map global user w '|muwrap<ret>'
