[rules-users] Re: How to create DSL template that produces rules based on arbitrary user's input?

You can do this. Keep in mind that the DSL engine will try to match each dsl mapping entry into the LHS of the rule, one by one, in the order they are declared in the mapping file. This means you can have one mapping that substitutes the word "and" for a comma, and so on. It may take some cle

Re: [rules-users] "or" not working

You must escape ( ... [condition][]\(=( But I'm not sure it will work, because expansion is doing nothing... I mean, text before and after expansion is the same and the system was designed to check for changes... Do you need to have ( alone in a line? Can't you use a more textual representa

Re: [rules-users] "or" not working

Thanks for your reply. Yes, I am using a DSL. So what you mean is I need to add 3 mappings in DSL like the following: ( mapped to ( ) mapped to ) or mapped to or right? I'll try that. Thanks a lot! On 8/8/08, Edson Tirelli <[EMAIL PROTECTED]> wrote: > >The error message indicates you are using

[rules-users] Use of a DAO in LHS

Hello, I have a DRL file in which I have a global variable representing a DAO. So, I succeed in writting a rule which uses this DAO to run a SQL query on the database from the RHS part. But now, I would like to use my DAO in the LHS, I mean I want to fire my rule only if a condition is ok on the r

Re: [rules-users] "or" not working

The error message indicates you are using DSL and the problem is not in the DRL, but in DSL. DSL requires every single line to be "matches" (or expanded), so if you have a line with a single ( and nothing more, either you have a mapping for it, or you escape the line with ">". Best way to

Re: [rules-users] "or" not working

You will need to give more details than what you are doing like the actual syntax of your rule. It looks like you are using a DSL, I would suggest you look at the actual DRL that DSL is outputting, then if you still have problems send that to the mailing list. Mark Yu Wang wrote: Hi, I need h

Outside of the WM. There are a number of rules in this decision table, but they all look just like this one. The way this works is that if it matches any of these rules, then it's an approved request. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Anstis

Well, IMO, common sense suggests highly specialised hand crafted code optimised to a particular problem domain *should* be faster than a generic algorithm (taking this further why not dump the high level languages all together and opt for C++ or assembler, if you really really want you squeeze perf
