This is a collection of various hacks

Well, not a very large collection right now, since there's only few hacks here, but still... :-)


The idea behind beam_renamer is to be able to load an erlang module (which is already compiled) under a different name. Normally, there's an error message if one does that:

1> {x, Bin, _} = code:get_object_code(x).
2> code:load_binary(y, "y.beam", Bin).

=ERROR REPORT==== 8-Nov-2009::22:01:24 ===
Loading of y.beam failed: badfile

=ERROR REPORT==== 8-Nov-2009::22:01:24 ===
beam/beam_load.c(1022): Error loading module y:
  module name in object code is x

This is where beam_renamer comes in handy. It'll rename the module by replacing the module name within the beam file.

1> {x, Bin0, _} = code:get_object_code(x).
2> Bin = beam_renamer:rename(Bin0, y).
2> code:load_binary(y, "y.beam", Bin).

See the comments in the source code for more details.


stem_en is an implementation of the English Porter2 stemming algorithm.

The implementation has been tested on the sample English vocabulary and produces an identical result when compared to its stemmed reference equivalent. Some performance figures: stems 400,000 words per second on a 2.53 GHz Core 2 Duo MacBook Pro.

stem_sv is its Swedish counterpart. Some performance figures: stems 900,000 words per second on a 2.53 GHz Core 2 Duo MacBook Pro.
