Chat Log filter request: wildcards or regexes

Dear forum mods,

could please inject this request into the regular proposal / feature request process? Devs should have no problem to understand what I mean. Thanks :-)

Dear Devs,

could you please, please, please (with cherry on top) increase the flexibility of chat log configuration by adding support for wildcards, substring parsing, or whatever? A simple standard solution with low dev efforts would suffice, no rocket science required, no special user interface required (a simple rule table which is maintained by direct chat log commands in /isort style would be perfect, as long as they are persistent).

Variant 1: database based wildcard parsing, e.g. by SQL or NoSQL query syntax or whatever suits best
Example 1: The % you put up for sale in the % markets % sold for % gil (after fees).

Variant 2: rule based substring parsing, e.g. by [e]grep-like implementation
Example 2: /grep [-add|del|list] [-v] <rule number> <regular expression>

Thanks and cheers,

Sol
