I know this doesn't quite answer your question but I find your approach a bit heavy for such (apparently) simple files to parse. Instanciating objects for each state will not help performance if that's what your aiming at. This leads me to my shameless plug: you should have a look at my tokenizer/parser modules and how I use them to parse JSON. You can find them here:
- Parser : https://github.com/Floby/node-parser - Tokenizer : https://github.com/Floby/node-tokenizer - parsing JSON : https://github.com/Floby/node-json-streams - A little article that I haven't finished yet about parsing : http://projects.flo.by/parsing-streams/ Hope this will help you. But I admit you'd need a good understanding of how closures work. On Wednesday, 6 February 2013 23:24:03 UTC+1, Ismael Gorissen wrote: > > So I need to parse .strings file.
