Hi guys, I'm looking for a regex that will change sth. like this: print "testcode $testvar \n"; in printnlog("testcode $testvar \n"); I tried %s/print\s*(.\{-});/printnlog(\1);/g but gvim says print\s*(.\{-}); doesn't match. Where is my fault? Is it ok to use '*' after '\s' because later '{-};' will stop the greed? Thanks in ...
In What regular expressions can never match? /$./ was given as a response. I played around with that a bit, and discovered that the following two lines of code generate different output. The second matches, but the first does not. Can anyone explain why? $ printf 'a\nb\n' | perl -0777 -ne 'print if m/$./m' $ perl -0777 -e '$_="a\nb\...

Does a regular expression exist for (theoretical) tryptic cleavage of protein sequences? The cleavage rule for trypsin is: after R or K, but not before P. Example: Cleavage of the sequence VGTKCCTKPESERMPCTEDYLSLILNR should result in these 3 sequences (peptides): VGTK CCTKPESER MPCTEDYLSLILNR Note that there is no cleavage after ...
I am using RewriteMatch to redirect all traffic from subdir1 to subdir2, while keeping all other parts of the url the same. So for instance, http://www.mydomain.com/subdir1/ would redirect to http://www.mydomain.com/subdir2/ I am using this rule: RedirectMatch 302 /subdir1/.* /subdir2/$1 which works for the url http://www.m...
Do I really get any benefit out of doing the following (as opposed to just putting the actual regex in place of the ${pcr} in both if statements)? (alot more lines are in the real data set but just using DATA for example. my $defs = 0; my $tests = 0; my $pcr = qr/\s*[\/\\]?\s*/; while (<DATA>) { $defs = ($1 ? 0 : 1) if /<(${pcr})d...
Suppose I have: my $string = "one.two.three.four"; How should I play with context to get the number of times the pattern found a match (3)? Can this be done using a one-liner? I tried this: my ($number) = scalar($string=~/\./gi); I thought that by putting parentheses around $number, I'd force array context, and by the use of scal...
I have a container of regular expressions. I'd like to analyze them to determine if it's possible to generate a string that matches more than 1 of them. Short of writing my own regex engine with this use case in mind, is there an easy way in C++ or Python to solve this problem? ...
I'm writing a function to "title case" strings e.g. "this is a title" to "This is a Title." The following line doesn't work because the regex group reference is lost (or so I assume). Is there an easy way to uppercase my matching letter in the replace function? replace( $input, '\b[a-z]' , upper-case('$0')) ...
Hello. I am working on a project that requires the parsing of "formatting tags." By using a tag like this: <b>text</b>, it modifies the way the text will look (that tag makes the text bold). You can have up to 4 identifiers in one tag (b for bold, i for italics, u for underline, and s for strikeout). For example: <bi>some</b> text</i>...

Hi all, I'm relativly new to regular expressions but I managed to create a working expression to validate dates (without leap years, and assuming people enter a valid 30 or 31 digit for a month). This is the expressen: /^\d[1-31]{2}\-\d[1-12]{2}\-\d[1900-2009]{4}$/ But I would like to have a dynamic regular expression like: $yearSpa...
