I have found myself in the situation where I would have Vim running in one window, and a terminal open on the other monitor with my tests. And noticed I was constantly dancing across the keyboard
⌘-tab;⌃-p;↩;⌘-tab (switch windows to Terminal; previous command; enter; switch windows to Vim). Of course this muscle memory was broken when I switched to my browser in between. I wanted to automate this.
I could use autotest, but our test suite is slow to start up and I wanted to focus on one test.
I could run that test within Vim, but MacVim does not show the color escapes when running a command, plus it blocks my editing while I wait for the tests to run.
I could use Vim in the terminal, but I like my ⌘ key mappings and colors.
How to do it:
Run your test in Vim, the line I would use is something like this (just replace the command bit with the one you want to run):
map <D-r> :silent execute "!ruby test/unit/post_test.rb &> /tmp/vim.log &" <cr>
And tail the logs:
$ tail -f /tmp/vim.log
Now when ever I press
⌘-r I can keep on tinkering with the code while the tests run on the other monitor.
I don’t keep that command in my
.vimrc file because I am constantly going back and changing the command – this has become a macro that I change around as I am focusing on different parts of my code.
q: to interactively edit and run past Vim commands.
Beauty of this is it works on any command, in any language I am programming in.
