[Java-readline-devel] Re: Inhibiting tab completion with java-readline

[Bernhard B. <ma...@ba...>]

Hi Ben,

I have been thinking about the issue of setting global readline variables 
already. I thought about writing one c-function and adding a number of static 
final int variables to the Readline-class. These could be private, the public 
methods (e.g. setInhibitCompletion()) would then all call the same method 
with the correct constant. On the other hand, if the variables were public, 
there would be even less java-functions (e.g. 
setReadlineVar(INHIBIT_COMPLETION,INHIBIT_COMPLETION_TRUE))

There are in fact quite a number of variables which could be exposed this way.

What do you think about that?
