[ragel-users] Enabling / disabling transitions depending on host language expression.

Yes, look for "semantic conditions" near the end of the ragel guide.

Subject: [ragel-users] Enabling / disabling transitions depending on host
 	language expression. 
 
Hello,

With Ragel, is there a way to enable/disable transitions depending on
the evaluation of an expression in the host language?

I have the following in mind:

main := m1 | m2 | m3

And I would like to inhibit entering m1 or m2 or m3 depending on runtime state.
Is this possible? If it's a wrong approach, what's the canonical Ragel
approach then?

Thank you,
Gregory
