Cygwin has a home directory where I can store a .vimrc file to set up syntax highlighting. I know on linux machines this file is usually in a home directory and that it can be stored globally (although I haven't figure out how the global thing works yet).
I'm windows user (I apologize), so I use different shells for different things, and am not all too sure why syntax highlighting is not working when I launch it from the git bash shell. It works fine for cygwin and for putty. but not so much for git's mingw32.
Another thing is that when I ssh to a remote server using cygwin, I cannot use Vim, but I can use Vim just fine when I connect using Putty's shell.
Any help on this topic would be greatly appreciated.
Git bash uses MSYSGIT, which comes with its own Vim . One way to look it up -
In your git bash type
$ type vim
it will tell you which vim executable is used. In my machine it points to
/bin/vim
if you type
vim --version, it spits out a lot of environment.
pipe it to a grep, like this
vim --version | grep vimrc and this will tell you the location(s) where this instance of vim will look for vimrc.
