Improving mvim for MacVim
MacVim comes with a clever script called mvim which allows you to open files in MacVim via the command line (much like mate for TextMate). This is a wonderful tool, but does possess some idiosyncrasies. It creates a new window (rather than a new tab) when you invoke it and it also won’t take stdin as input unless you pass a dash1.
To fix this I modified the script to check for an existing macvim process, and if it exists attach tabs to it.2 Additionally, it checks for args and if none are present (or just -) the script invokes stdin. I am not much of a bash hacker though, so there are a few caveats…
-
–remote-tab-silent doesn’t seem to work with listening on stdin, so the script always pops it out into a new window.
-
You (apparently) can’t pass extra parameters when using –remote-tab-silent, so tricks like mvim /etc/hosts +5 to have it open with the cursor on line 5 will not work.
These are both irritating, but I feel the advantages outweigh the disadvantages. Hopefully someone can contribute fixes to these problems!
