Collect filenames of current subtree

In Vim you can edit directories, but sometimes it is more convenient to have the names of all files in the complete subtree listed in one buffer. The netrw plugin which creates the directory listing can be tweaked to show a tree view, by using the g:netrw_liststyle variable in your .vimrc or from the command-line before invoking the directory explorer:
Sometimes though, you may simply want to list out all the files in a directory tree in a buffer. The below function does just this. It globs the file names of the current directory and iterates through all the names, globbing it again if it is a directory. Note, it can be very slow for large directories.
The following mapping abbreviates the invocation to pressing
map <Leader>L :call ListTree('.')<CR> function! ListTree(dir) new set buftype=nofile set bufhidden=hide set noswapfile normal i. while 1 let file = getline(".") if (file == '') normal dd elseif (isdirectory(file)) normal dd let @" = glob(file . "/*") normal O normal P let @" = glob(file . "/.[^.]*") if (@" != '') normal O normal P endif else if (line('.') == line('$')) return else normal j endif endif endwhile endfunction
