Add cider-find-ns

[expez]

Here are some very common situations for me:

1. I know some function exists, but I don't recall the exact name.
2. I think maybe some function exists in lib and I want to check before I write it myself

I'm solving these now by using cider-classpath, C-s down to the lib, open the jar, look at the list of files and then picking something that looks promising.

cider-find-ns would give a completing read of all the available namespaces available on classpath, not just in my own project, and jumps to the selected ns.

If memory serves there's no mapping between namespaces and source files. How would you propose to tackle this? Maybe just use the info from a random var in the ns?

tools.namespace has everything we need to implement this. Specifically we can build a tracker for everything on classpath. The tracker has a :filemap which is a map of namespaces to files.

PR welcome, then! :-)

Anyone working on this?

[expez]

Guess I'm not most likely candidate and I haven't gotten to it yet

@expez When/if you get to this, maybe the ns-list op could use tools.namespace as well ?!

[alexander-yakushev]

Does the ns-list returns only the list of namespaces, or their content as well?

[expez]

@alexander-yakushev what we need to implement this is a map of ns => file which can be created using tools.namespace.

[bbatsov]

Yeah, this will probably be easy. The problem is that we'll also need to check if a namespace is loaded or not when we use this in places like the namespace browser. This shouldn't be hard, but still - it's a work we have to do.
