Get CLI results in Vim

Still a nice trick. When you need to get the results from a command line into your documentation, you can use Vim's ability to run Bash / Zsh commands and read their outputs.

For instance, I want to list all the files contained into a directory:

:r ! ls -l my_dir

Another nice example, I want to show the directory tree of my project into my documentation :

:r ! tree -d

Note : On OSX, you can install tree with Homebrew easily:

brew install tree
