I recently discovered Squirrel and after very short time it become my favourite scripting language in place of Lua. I find it small, elegant without clumpsy Lua syntax. Well done, Alberto!


However, I miss more examples and I would like to change it. The following is a simple class and generator for dealing with text files which I found a bit tricky in Squirrel.
