[ruby-talk:11200] Re: Fw: Re: [agenda-dev] Python

I have just recently acquired a PDA that runs linux, the Agenda VR3.
It runs a MIPS based NEC chip, the VR4181 I think. It is still in
developer version, and lots of people are writing open-source linux
PDA applications for it, using FLTK as the default GUI toolkit.
The default scripting language for the device has not been decided yet, 
although Python & Ruby seem to be the main 2 contenders. 

I would like to try to encourage the use of Ruby as the default, but I 
don't know if anyone has actually successfully compiled ruby for the 
device. The main advantages of ruby I think seem to be smaller interpreter 
size & smaller FLTK bindings (I don't think Ruby's FLTK bindings use SWIG
- somebody correct me) Python's FLTK bindings are more mature though,
it seems, and more people seem to know Python than Ruby. 

Sorry about the longish unsnipped discussion below, but I didn't know how 
else to get across the context of the discussion they've been having. If
anyone has any tips about compiling ruby for strange MIPS chips or reducing
the size of the interpreter or libraries James Fenn (email below) would
probably be a good person to get in contact with, or alternatively, if
people don't mind, mail them to the list or mail them to me & I'll pass 
them on.

> Ruby with all of the relevant c libraries compiled in (minus ncurses module, tk module, etc) is around 700k on my i386 box and the native libs when compresed about 200k - This is for fully featured ruby. Without any bells and whistles, it's about 520k. But the bells and whistles are nice :)
