Re: Function To Search Directory And Display File List
Well, as an ugly first-pass hack:
:let s = expand("*template")
:echo substitute("\n".s."\n",
'^\%([^[:cntrl:]]*[[:cntrl:]]\)\{'.(confirm('Which file?',
s)).'}\([^[:cntrl:]]*\).*', '\1', 'g')
Thanks a *ton* Tim! This looks very succinct (if not a bit
frightening). I'll definitely try this one out too.
The 10k foot view is "offer the user the list of files (the
confirm() call) extract the Nth position from that list of files
as determined by the index returned from the confirm() call".
Wow, I'm glad that I started Vim scripting after version 7 was released,
because it looks like it was much more difficult to script using version
6.
Vim7 added lists (among other more advanced datatypes, IIRC)
which makes this hack considerably less taxing. The above hack
is a way of treating a string like a list, using the newline
characters (which happen to be control-characters, and thus match
the POSIX-type [[:cntrl:]] notation) as demarcations between list
items.
You could probably change the
"\n".s."\n"
to just
"\n".s
as, looking over it, it doesn't seem to require something
following the item of interest.
Hope this helps make a bit more sense of the chaos. :)

Re: Function To Search Directory And Display File List
Try :set wildmenu I put the above line in my .vimrc file and now can do the following: :e *s*#then hit tab and any file in the current directory that contains an 's' is displayed in a menu.

1. Searches a directory for all files that end in the string "Template"
2. Return those file names to the user as chooseable list, similar to
the way that the spell checker functionality works when you use the z=

Well, as an ugly first-pass hack:
:let s = expand("*template")
:echo substitute("\n".s."\n",
'^\%([^[:cntrl:]]*[[:cntrl:]]\)\{'.(confirm('Which file?',
s)).'}\([^[:cntrl:]]*\).*', '\1', 'g')
Those two lines create a prompt with available matches for
whatever is stashed in "s".
Instead of an :echo you can do an assignment, or make it the
return value of a function so you don't have to recreate this
beast repeatedly.
It can be wrapped in a function if desired. Hari's suggestion
was a good one, but requires Vim7 (at least it didn't work on 6.3
when I tried it because of the need for the inputlist() and
split() functions). As you reference the "like spell-checker",
you're likely running 7.0 and thus are safe with his much clearer
method.
The above two-liner, despite its brutish opacity, should work at
least back to 6.0.

If all that you want to do is ability to search and open the file, one of the existing plugins might be able to help you. But if you want to ask the user to select one and do something with that selection, you can use the glob() and inputlist() functions to do this, something like this: let files = glob(dir.'*Template') if files != '' let filelist = split(files, "\n") let sel = inputlist(['Select file:']+filelist) if sel != -1 let selectedFile = filelist[sel] endif endif -- HTH, Hari __ Do You Yahoo!?
