precompile-regexp

Description

The function precompile-regexp returns a precompiled regular expression object suitable for passing as pattern to functions like find-regexp-in-string.

case-sensitive controls whether string is precompiled as a case sensitive or case insensitive search. A non-nil value means a case sensitive pattern. The value nil (the default) means a case insensitive pattern.

error-function is used when the string is not a legal regular expression. In this case, if error-function is not nil, it is applied to a list of arguments which are designators for a condition like the arguments that error takes. If error-function is nil, precompile-regexp returns nil as the first argument and the list of arguments as a second return value, condition-designators. error-function defaults to error.
