FastRI is an alternative to the "ri" tool, used to browse RDoc/RI Ruby API documentation. As of 0.3.0, FastRI can operate in standalone mode (without using a DRb server, see below), so it can now fully replace ri for most intents and purposes. Why prefer it over ri? FastRI actually works is much faster than ri can perform fast full-text...

rcodetools is a collection of Ruby code manipulation tools. Currently, rcodetools comprises: xmpfilter: automagic Test::Unit assertions/RSpec expectations and code annotations rct-complete: 100% accurate (editor-independent) code completion rct-doc: document browsing and code navigator rct-meth-args: precise method info (meta-programming aware)...

If you've ever written a piece of code that worked fine in a Rails app but bombed elsewhere, you've probably been relying on a Railism unknowingly. I used rcodetools' rct-meth-args to generate a list of Railisms (extensions to the core/stdlib classes), by processing an intermediate tags file*1. The list is fairly comprehensive, since it takes...

You have heard about latent semantic analysis (if you haven't, take a look at this nice article on a SVD recommendation system written in 50 lines of Ruby). And you told yourself "hey, this is cool", to file it in your head right away. Or maybe you tried to actually use it, but were scared off by the algebra 101 part, or got lazy when you...

WEBrick isn't as fashionable as it once was, but it's still invaluable for development and testing. I recently needed it to handle rewrite rules, and google didn't return anything better than Simon Strandgaard's code. On that same thread, GOTOU Yuuzou indicated that he wanted to add proper URL rewriting support to HEAD (1.9). It's been two...

Overview rcodetools is a collection of Ruby code manipulation tools. It includes xmpfilter and editor-independent Ruby development helper tools, as well as emacs and vim interfaces. Currently, rcodetools comprises: xmpfilter: automagic Test::Unit assertions/RSpec expectations and code annotations rct-complete: 100% accurate...

_why has repainted eigenclass.org, and made me realize that eigenclass' design can be tiring to the eye if you've not set your monitor to fairly low brightness & contrast levels (which I have). I used a quick Ruby script to rewrite the CSS stylesheets (making most colors 20% darker), and you're getting a new logo with a 50% probability on...

The first attempts to optimize my pure-Ruby, 200LoC full-text search engine based on suffix arrays (which evolved into the in-progress FTSearch) led me to perform some n-gram analysis over Ruby's core/stdlib docs (as well as a pack of gems). With a suffix array, locating a word in the corpus involves a binary search of complexity , N being the...

Seeing the bar turn green is great for the morale; this is one of the several benefits of writing tests (even if you don't go fully TDD). Running tests manually can disrupt your workflow, though, so we're all using autotest to have our tests executed in the background continuously. autotest includes a number of extensions to notify the result...

The last time I blogged about the FTSearch (simple) full-text search engine, it already indexed the Reuters corpus over twice faster than Ferret. I have rewritten a few more methods in C and got an extra 50% speed boost, making it now over 3 times faster than Ferret when indexing. Today's news is that I've implemented enough functionality to...
