I think I might make another page in the settings to allow one to choose what fields to search in and possibly which to display as details. I plan on embedding the code to search ports right in NPM, but if it doesn't clog things up I don't see why not to allow the ability to use an external program. The best reason being if the index file ever changes or is ax'ed and I get hit by a bus, no one has to learn Python to fix NPM lol.
A couple months ago I sat down and started trying to figure out the format of the index file in ports, it was pretty easy and I wrote a small script to search it and print out all the cells of information in each entry of the index that had a matching package-version in it.
This is a quick test script I wrote tonight that searchs for a port and displays a short info on it, being a test I wrote the port to look for in the file test rather then passing sys.argv over to save time. I plan to adopt NPM to using a variation of this for searching ports now.
