Since there may be specific operations you want to perform on the selection returned from a tlib#input#List(), I implemented a new function
tlib#cmd#BrowseOutputWithCallback(callback, command) that executes the CALLBACK function passing the selection as an argument.

As a practical example of this new functionality, I also added a new TBrowseScriptnames command that allows you to select from the :scriptnames output and opens the selected file in the current window.

(I also reimplemented tlib#cmd#BrowseOutput(command) using a callback for DRYness.)

I wrote documentation for these, emulating other tlib documentation; but I wasn't able to determine how you generate the help docs from this markup (I sure would like to know! :-)

Please let me know if you would like me to make any further changes before accepting, or if you don't think this is an appropriate addition to tlib.

Thanks. I was somehow surprised that TBrowseScriptnames wouldn't let me select multiple files. But since tlib#cmd#BrowseOutputWithCallback() is a general purpose function using single selection is safer.

The docs are generated with vimdedoc.rb (see I'm not happy with the script's code but it works for my own vim plugins.

I wasn't familiar with multiple selection from a tlib#input#List(), so that's the main reason it's not there. I could add it, if you like. I think it should be pretty easy to check in the callback whether the incoming argument is a String or a List and act accordingly.

I'm not sure what the proper behavior would be in the case of multiple selections for an "edit file" callback. Add all of the files to the arglist? Edit all of them in turn, leaving the last one active? Create new splits for each? New tabs? Use some existing setting to determine proper behavior?

As long as nobody misses it, there probably is no use in improving the function.

Most of my tlib-related plugins usually edit the files right away. People who stay closer to vim's spirit would probably prefer adding the files to the arglist. An extra option could be of use for those plugins too. Could it be the command to use? E.g.

let g:tlib_edit_cmd = 'edit'

Users could also set it to: arga, split, vert split, tabe
