Go – Add GoLang syntax highlighting for VIM

govimvim-pluginvim-syntax-highlighting

I'm trying to add Go language syntax highlighting to VIM on ubuntu with resources and direction supplied here http://go-lang.cat-v.org/text-editors/vim/.

Go comes with a go.vim file that contains syntax settings for VIM and the above page offers the following instructions

Place $GOROOT/misc/vim/syntax/go.vim in ~/.vim/syntax/ and put the following in ~/.vim/ftdetect/go.vim:

au BufRead,BufNewFile *.go set filetype=go

This is more or less the same vein of procedure for customizing vim syntax I've seen elsewhere
(Vim 7.3 on Ubuntu 12.10 doesn't have 'ftplugin' directory anywhere and https://github.com/jnwhiteh/vim-golang/blob/master/readme.txt)

So I think I'm doing the right thing when I create directories:
~/.vim
~/.vim/syntax
~/.vim/ftdetect

and follow the above instructions by adding

go.vim to ~/.vim/syntax/
and creating a file, go.vim, in ~/.vim/ftdetect/ which contains

au BufRead,BufNewFile *.go set filetype=go

Yet syntax highlighting does not seem to occur. Is there something I need to do to force VIM to look at these new settings files?

UPDATE:

Go 1.4 Release Notes

Miscellany

The standard repository's top-level misc directory used to contain Go support for editors and IDEs: plugins, initialization scripts and so on. Maintaining these was becoming time-consuming and needed external help because many of the editors listed were not used by members of the core team. It also required us to make decisions about which plugin was best for a given editor, even for editors we do not use. The Go community at large is much better suited to managing this information. In Go 1.4, therefore, this support has been removed from the repository. Instead, there is a curated, informative list of what's available on a wiki page.

The standard Go distribution includes Go files for Vim in go/misc/vim/. This directory contains a readme.txt file which contains installation instructions.

Vim plugins for Go (http://golang.org)

To use all the Vim plugins, add these lines to your $HOME/.vimrc.
" Some Linux distributions set filetype in /etc/vimrc.
" Clear filetype flags before changing runtimepath to force Vim to reload them.
filetype off
filetype plugin indent off
set runtimepath+=$GOROOT/misc/vim
filetype plugin indent on
syntax on
If you want to select fewer plugins, use the instructions in the rest of this file.

Use `\r` instead of `\n`.

Substituting by \n inserts a null character into the text. To get a newline, use \r. When searching for a newline, you’d still use \n, however. This asymmetry is due to the fact that \n and \r do slightly different things:

\n matches an end of line (newline), whereas \r matches a carriage return. On the other hand, in substitutions \n inserts a null character whereas \r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it). xxd shows a hexdump of the resulting file.

echo bar > test
(echo 'Before:'; xxd test) > output.txt
vim test '+s/b/\n/' '+s/a/\r/' +wq
(echo 'After:'; xxd test) >> output.txt
more output.txt

Before:
0000000: 6261 720a                                bar.
After:
0000000: 000a 720a                                ..r.

In other words, \n has inserted the byte 0x00 into the text; \r has inserted the byte 0x0a.
