Another issue with exclusive line-orientation is that ack BR> can't search across line boundaries (I'm not 100% sure, so if I'm BR> wrong, please correct me). i have been mulling over those ideas and i think i have something which may sort of work. instead of the array of lines for the shift register, we use a string buffer as a text shift register. (this is only for when the word/char context options are selected). new lines get appended to the buffer, and matches are done against the buffer text. the match will include the appropriate amount of context to grab (optional as it could be near begin or eof). you would also need to only match when you have enough context in the buffer (like the before/after logic we are using for the line version). once a match is found it is printed immediately since we know we have all the desired context in the match already and we grabbed the whole match. and we can trim off text from the beginning of the buffer when we have enough text in it. plenty to be worked out but i think the concept is valid. but let's see how the lines versions goes before we tackle these options. thanx, uri -- Uri Guttman ------ [EMAIL PROTECTED] -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Free Perl Training --- http://perlhunter.com/college.html --------- --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- _______________________________________________ Boston-pm mailing list Boston-pm@mail.pm.org http://mail.pm.org/mailman/listinfo/boston-pm
