in thread Any news on Compress::LZW?

I'd have done this myself if I didn't already know that there might be good ways to cheat and get better performance on memory, cpu or on the API. I really wanted SomeGuru to pick it up. *shrug* Having the original paper around would be pretty handy as well.

    SomeGuru, eh? Don't know him. :) Actually, I looked at the code (dont tell:) and it's just the LZW algorithm in perl... it doesn't output in any sort of data format, so there's work to be done there, and it doesn't have a decompressor (likely because there is no set data format :). I'm going to poke around some more on the subject... I'll also look at that Compress::SelfExtracting to see if the LZW can be isolated (and optimized, if it really is dog-slow).

    Update: I've pulled the compression code out of Compress::SelfExtracting. It's working perfectly... got a 2.91:1 compression on a text file I had laying around :) We'll see if the author cares about his code being repackaged :)

[Corion]: Meh. I think I have now the parts down that I want from a simple Javascript frontend for single-page- applications with a aPerl backend. But it seems that all Javascript templating modules either don't support two-way binding (which would be nice) or ...
[Corion]: ... don't support server-side precompilation (which means the client has to compile all templates to Javascript themselves), or are giant frameworks that expect to do everything (which is not what I want)
[Corion]: I feel that there is a talk somewhere in there, either about the structure and parts, or how I used several parts to get a complete whole.
[Corion]: Maybe I can still find something that is compatible with handlebars.js (which has JS precompilation) but allows for two-way data binding (which is great for the UI)
