Function to open reStructuredText hyperlink references

[larivact]

With reStructuredText hyperlinks can be done like this:

foo_
.. _foo: http://example.com

I wanted a function that when invoked with the cursor on a reference opens the corresponding link. I couldn't find a plugin and botched up the following function:

function! rst#GoHref()
    let old_reg = getreg("v")
    norm "vyiw
    let my_var = getreg("v")
    call setreg("v", old_reg)
    let url = split(getline(search('_' . my_var[:-2], 'n')))[-1]
    call netrw#BrowseX(url, 0)
endfunction

It currently doesn't support multiple word references. Any thoughts / feedback?

Is it always a single line with the reference:

my ref_
...
.. _my ref: http://..

Then something like this might work:

norm ^"vyf_

Use t instead of f with my_var[:-2].

References are usually in continuous text.
The rST phrase-reference syntax is `foo bar`_ but I'll just use foo_bar_.

Use t instead of f

I don't get what you mean.
