I'd like back all the hours I've spent over the years trying figure out the correct incantations of quotation marks and escape characters to get computers to do what I want with some text.
Hey Canadian nerds! I have held the domain registration for regex.ca for a very long time. When I lived in Canada it was my primary domain, but I haven't used it for years. Does anyone on the fediverse have a good use for it?
I'm going to release it but if you've got a good pitch I'll pay for a 1 year renewal and then transfer it to your ownership.
@tripleo You’re thinking of #Perl’s “taint mode” (stop your teenage giggling), where outside data is untrusted unless it’s the extracted subpattern match in a #RegularExpression.
If you work with text data in R, the gregexpr() function is essential for pattern matching. It finds all occurrences of a pattern within a string. Key parameters include pattern, text, ignore.case, perl, fixed, and useBytes. You can match characters, ignore case, use advanced regex, and search fixed strings.
In my latest blog post, I cover how to find specific strings in data columns using the str_detect function from the stringr package and base R functions. You'll see practical examples with both grepl for identifying matches and gregexpr for counting occurrences.
