#regular expressions

[poondaedalin]

I've recently been messing around with a Firefox extension that lets you replace text on websites based on matching text or a regular expression

So my first instinct was to look at Scientific American and replace the word "AI" with "the wizards"

Fun with LazyTown transcript data

I downloaded transcripts of all 78 episodes of LazyTown and have been having fun using regular expressions with the SublimeText search function to look stuff up, because yes, I am that nerdy. :D

Unfortunately, the transcripts aren't perfect, as I think they might have been ripped from Youtube's auto closed-captioning feature. (For example, several episodes feature a character named "Sporticus.") But they saved me the trouble of transcribing each episode myself, and beggars can't be choosers. Anyway!

Robbie refers to Sportacus as an elf 7 times, across six episodes.

The word "apple" appears 129 times, across 37 episodes.

Times Robbie (or anyone else) refers to his Rotten Plans™ as "schemes": exactly 1 (and it's in the very last episode, too).

Most common nickname by Robbie for Sportacus in season 1: Sportakook (research is ongoing for seasons 2-4, but preliminary data suggests Sportaflop takes the crown in season 3).

Blue insults include: blue-suited blowhard blue buffoon blue elf blue jumping kangaroo blue typhoon blue snoop blue cartoon

Ways the transcriber spelled "diggiriggidong": diggiriggidong digga-rigga-dong digga-wigga-dong digga-rigga-dog digga digga dung diggi-riggi-dong digga-digga-dong dig-a-brig-a-dong dingi-riggi-dong digga bigga dong diga-wiga-dong dingaringa-dong dig-a-rig-a-dong diggiriggi dong

Example of searching for Sport- nicknames below the cut

I'm currently using this regular expression to search for nicknames:

sport(?!(acus|icus|s\>|[[:space:]]|[[:punct:]]))

This looks for the letters "sport" but NOT followed by "acus", "icus", "s" and then the end of the word (so not the word "sports"), a whitespace character, or a punctuation character. It is not case-sensitive.

And here's what it looks like when I run my search:

As you can see, it's easier to tabulate "uses of the word 'elf'" or whatever than all of Robbie's nicknames for his nemesis, but I think it's research worth doing. :D

Im going over regex fundamentals and if anyone could help I'm having trouble with this lesson:

RegexOne provides a set of interactive lessons and exercises to help you learn regular expressions

I even had the solution it says is correct but it seems to not be accepting it?

Transcript Under the Cut

Megan: Oh no! The killer must have followed her on vacation!

[Megan points to computer.] Megan: But to find them we'd have to search through 200 MB of emails looking for something formatted like an address! Cueball: It's hopeless!

Off-panel voice: Everybody stand back.

Off-panel voice: I know regular expressions.

The word PERL! appears in a bubble.

I am a little confused why I never hear about regex libraries compiling regexes to a list of function pointers.

From my naive initial think at the problem, seems like you could save a lot of branches that way; a good middle ground between

the usual approach of compiling to an intermediate representation which is only more-efficiently interpreted, and

the heavyweight approach of JIT-compiling the regex to actual machine code.

did you know Go's regex engine has a repetition limit? me either! that & more in my new journal entry :3
