I've attached a patch to add a "go" filetype to vim, with syntax highlighting and filetype configuration. I also updated the vim-ft-vroom repo URL to point to the renamed repo while I'm at it ("vim-ft.vroom"->"vim-ft-vroom").
These files originally came from the golang repository and are currently maintained at https://github.com/google/vim-ft-go. The files are under a BSD license there, but I've obtained approval from Google to include them in vim under the Vim license. David -- -- You received this message from the "vim_dev" maillist.
