Description: |
The attached patch extends the basic conversion of static RE to simple glob in several ways ... * TclReToGlob function created that does some more extensive conversions, but still conservative to what is possible * Add INST_REGEXP that does simple [regexp ?-nocase? ?--? $exp $str] fully compiled * Use TclReToGlob in the compilation of regular expressions and cache the result * Use cached glob whenever a RE evaluation is requested that matches the profile (has glob equiv, doesn't request match info, no offset, etc) | |||

Logged In: YES user_id=72656 Originator: YES Applied for 8.5b3. Note that this also takes effect in some -regexp option usage by commands (wherever Tcl_RegExpExecObj is called with 0 offset, 0 matches and 0 flags with an RE that has a glob equiv). hobbs added on 2007-11-12 09:01:54: File Added - 253873: retoglob.diff |
