Hey Scott, GREP is wonderful stuff, but be prepared to bang your head against the wall more than a few times. :) A useful tool: http://gskinner.com/RegExr/ Speaking of which - I'd sure like to see BBEdit have a means to do live regex-match for prototyping patterns. This pattern assumes your url is on one line and that the final backslash is at the end of the line. Find: http://.+?/([^/]+)(/)$ Replace: <a href="&">\1</a> Parentheses represent captures. Find: 'http://' Literal string. '.+?' Any character, more than one, non-greedy. '/' Literal string. '[^/]+' Any character NOT '/'; more than one. '/' Literal string. '$' End of line. Replace: '&' The entire matched string '\1' The 1st capture. Another way to do it using positive lookahead assertion: Find: http://(.+?(?=/)/)+(.+?(?=/))(/) Replace: <a href="&">\2</a> You can find that on p. 179 of the BBEdit manual under Perl-Style Pattern Extensions. BTW - now is a very good time for you to start writing text filters too. You can save them and build up a library of examples. I've create a default text filter and given it a keyboard shortcut of Ctrl-J. I've also written a script to open that file in BBEdit and given it a keyboard shortcut of Ctrl-Opt-J. This makes it very convenient to write and execute a text filter — more convenient in some respects than using the find/replace dialog. ------------------------------------------------------------------------------------------- # PERL TEXT FILTER USING THE SAME REGEX AS THE FIRST EXAMPLE ------------------------------------------------------------------------------------------- #! /usr/bin/env perl use strict; while (<>) { s!http://.+?/([^/]+)(/)$!<a href="$&">$1</a>!; print; } ------------------------------------------------------------------------------------------- # A SIMPLE FIND/REPLACE TEMPLATE ------------------------------------------------------------------------------------------- #! /usr/bin/env perl use strict; while (<>) { # You can have multiple find/replace actions. s!FIND-PATTERN!REPLACE-PATTERN!; s!FIND-PATTERN!REPLACE-PATTERN!; print; } ------------------------------------------------------------------------------------------- Note that you can change the ! separator to other characters like '/', '#', or '~'. Perl will only find the first match unless you tell it otherwise: s![a-z]+!•!gi; 'g' = global 'i' = case-insensitive The default is a forward slash, but sometimes that's hard to read - especially when you have to escape a bunch of characters. Note also that in Perl capture references use the dollar sign instead of the backslash. Text filters are saved here: ~/Library/Application Support/BBEdit/Text Filters/ See the manual for more information. -- Best Regards, Chris -- -- You received this message because you are subscribed to the "BBEdit Talk" discussion group on Google Groups.
