Die namespace, die

[Dave Ray]

Hi,

Often when testing or working with multi-methods, I want to completely
obliterate a namespace and start from scratch. So I added this to my
.vim/after/ftplugin/clojure.vim:

function! s:ResetNamespace()
let ns = foreplay#ns()
" switch to neutral ground, kill the ns, switch back to the ns.
let cmd = "(in-ns 'clojure.core)(remove-ns '" . ns . ")(ns " . ns . ")"
echo cmd
try
call foreplay#eval(cmd)
catch /^Clojure:.*/
return ''
endtry
endfunction

" Command that brutally guts a namespace.
command! -buffer -bar ResetNamespace :call s:ResetNamespace()

It leaves the ns empty so you'll have to re-require.

Anyway, I've found it very useful, so I thought I'd share and solicit
feedback, especially on the lame VimL cribbed from foreplay.

Cheers,

Dave

Hi,

you might want to use in-ns instead of ns to switch back. Using ns sets up all reference to clojure.core which will lead to trouble in case you want special treatment there:

(ns foo.bar

  (:refer-clojure :exclude (==)))

As a rule of thumb: ns is not about namespace switching.

Thanks Meikel. Good point. I try to avoid needing :refer-clojure if I
can help it so I don't think about it much :)

I think you could also use https://github.com/clojure/tools.namespace 

I use it and it works great so far.
