If you’ve ever tried to search Google for code you know it can be a pain. There are several special characters that Google doesn’t recognize, sometimes it seems like Google’s looking in every place except where you want to look, and Google’s syntax don’t always work well in narrowing down your search for code.
Enter Krugle. Krugle, at http://www.krugle.com/, is a search engine specifically designed to find code, with several ways to narrow down your searches.
I did a search for Perl files containing the word Excel in the comments (trying to answer the question “How are people using Excel and Perl?”) I got 763 results, listed in groups of ten. Results included a snippet, file name, and the domain from which the information came.
In addition to the code tab (where you can do these code searches), there are two other tabs as well. There’s a Tech Pages tab, which searches for documentation, tutorials, etc. (Searching for Spreadsheet::WriteExcel got me over 125 pointers to information, including tutorials, general information pages, and a wiki or two. Unfortunately it also brought back some cruft like lists of Perl modules installed at hosting companies.) There’s also a projects page; enter a query string and get all projects which match that string (searching for Excel here found 30 projects, including a couple I’m going to have to look at further…..)
If you’re not much into programming, skip the code search and see what the Projects and Tech Pages tabs have to offer. There’s a little bit of searchgunk, especially in the Tech Pages results, but it’s easily avoided. I could spend a lot of time here…
