Hi,

I have an equipment db which i add to using a data record.

syntax in triggers that i use is

#addkey recordname keyword %trim(%1)
and so on

Ive noticed that if i have the following item (and similar) to add to the db

keyword pole arm
Name ----Pete's Polearm-----)>
weight 18

etc

the data record gets entered as follows

recordname:

data record view

keyword |pole arm - as it should
Name |----Pete's Polearm-----)>weight|type|level|etc|etc - incorrect

instead of

recordname:

keyword |pole arm
Name |----Pete's Polearm-----)>
weight |18

etc

I know its to do with the meta characters. How do i prevent this from happening?

Thanks

Use %subchar to get rid of them before adding it to the record. The biggest one to cause a problem is parenthesis "()". They are used internally to preform nesting of lists and records within lists and records.

Thanks for the reply.

I thought about using %subchar but this posses a problem for adding certain items to my db from the mud

E.g one item is this:-

:::[======-

or lets say it was

:::([======-

another item

.=very large club=.

or

+->sword>-+

For the ones with words i could remove all the symbols and still have something to put into the db.However, with
the first example i would have a blank entry. Do i use %subchar to get rid of the big problem causers like paranthesis as you mentioned and hope the others dont mess the script up?

Hi,

Has anyone got any ideas on this? Would some sort of translation be a solution? i.e :::[======- convert to some other characters before updating to the DB?
Or is there a way to encapsulate the meta characters so that it can be entered into the datarecord correctly?

Regarding your problem. You don't have to replace every char, only parentheses, and "" symbols. Parentheses because as Vijilante said they're used internally for nesting and grouping. Similarly, "" symbols are used to group parameters supplied to commands.
Any item containing only these will of course be a problem, but its doubtful you'd have very many. A record named :::[======- shouldn't cause a problem. You wouldn't need to replace any of the characters. So long as you're careful to group each field to be added to the database with "" or {}.

Thanks Danlo. Tested it with a few variations and it works.
