iRule Manual

Rumor has it there is something like this in the works but I don't know the status of it. In the mean time, we are starting to put on steam with our 101 series of tech tips and this one is a pretty good one to start with. How about for my next tech tip (by the latest of next Thursday), I'll do a write-up on iRule Syntax. If you have any other ideas, please let us know and we'll get them in the pipeline for upcoming tech tips.

If it's brackets and such that you're having problems with then you should look for TCL references, not iRule ones. iRules are built in the TCL language, and it sounds like the problems you're having are language related.

 

 

TCL is (as I like to put it) "simply complex". The actual rules behind the language are incredibly simple, and there's really very little to them. However, they interact in some quite complex ways.

 

 

Usually I use the TCL reference liked to by the iRule editor:

The basic rules of the language as far as what the different kinds of brackets do are here:

I'd suggest giving that a read (or maybe 3), and also looking at some of the control construct documentation. It's helped me a lot (though I still get easily confused).
