Via Github I use the same set of "dot files" on several different computers and servers. On the Macs and Linux boxes under my direct control I have Sublime Text 2 installed and set up as my git merge and commit editor of choice. However, on remote (i.e., not under my direct control) servers I would select to use vim.
I would rather not create and maintain a second .gitconfig for those remote servers. Is there a way to do something like this:
[core]
if [[ $IS_REMOTE -eq 1 ]]; then
editor = "vim"
else
editor = "subl -n -w"
fi
where I've somehow set $IS_REMOTE based on the hostname?
Since it isn't possible to test an environment variable and programmatically alter the .gitconfig, and since scripting the creation of two .gitconfig files feels like more work than I really want to put forth, I'm just going to create two .gitconfig files. On those machines where I can setup Sublime Text 2 as my editor, and have control over the merge tool and diff tool, I'll use the "primary" gitconfig as the target of my symbolic link. On those machines where I don't have ST2 as an option, I'll use the "secondary" gitconfig file.
