I'm looking to create a really simple Vim plugin. Basically, for a given file extension, when you save the file in Vim it should run an external command and then refresh the file in Vim.
Digging around, there doesn't seem like a great reference for creating a Vim plugin. This one seems to be about it, but there's a good chance by googling skills are lacking this morning.
Any recommended tutorials or references I should look at?
