I thought the expression parser will come in handy. :)

I got an Duby update, and had to make one minor change to get dubyline to
compile under 64-bit Linux. See patch below.

Anyway, I simplified your instruction on integrating Duby with Lazarus IDE
as well. Simply add the following to the "Tools > Configure Build Lazarus >
Advanced tab > Other" dialog and edit box. Obviously change the paths to
match your environment.

  -Fu/opt/git/duby_svn/dubylib -Fu/opt/git/duby_svn/dubylaz

Then simply add 'dubydebugger' to uses clause of the DebugManager.pas unit
included with Lazarus IDE.

No need to copy Duby units to the Lazarus source directories - keeps things
a bit more tidy, and development in Duby can continue, and when Lazarus
gets rebuilt, Duby updates are automatically included (again no copying of
units required). :-)

Duby appeared in the debugger list of Lazarus IDE, but I couldn't get it to
debug a program though. I couldn't start my application via the IDE. :-/
Any hints?
