Run Reia module on top of YAWS
Reported by Philipp Pirozhkov | November 6th, 2008 @ 01:20 AM
Since we need to have support for web applications, it's a good idea to use a mature web servers, one of which is YAWS. So it would be nice to be able to run such a module in YAWS: module A def out(a)
(~html, "Hello, World!")
with minimal Reia changes and YAWS configuration

I've tried to do so, but ran into two issues: 1. Erlang doesn't want to load modules with Capitalized module name (not file name!). 2. Reia outputs data with type declaration attached, so instead of: {html, "Hello, World"} we are getting {tuple, {html, {string, "Hello,World"}}}
I've changed parser so that all module names are compiled to be lower-case in .beam files. But that breaks dispatcher and tests (and even ire itself), so that all that stuff should be changed to use lower-case module names. secondly i've patched reia_string (moved its functionality to reia_list), Tuple, reia_dispatcher to remove type declarations. both are bad ideas, uh?
Tony suggested to use a simple shim between Reia appmod and YAWS: -module(my_shim). -export([out/1])
out(Arg) -> reia_erl:r2e('A':out(reia_erl:e2r(Arg)).
This seems to solve both issues.
