Day 1: Trebuchet?!

I found this really tough for a day 1 problem. Because I don't really know regex, I did not know the secret to finding overlapping patterns. I quickly figured out that "twone" was a possibility, because it was in the example, but then I had to find other examples and hardcode them into my split pattern.
This isn't general, my input doesn't have 'sevenine' for example.
Abso-fucking-lutly. I just find sharing a link easier than wrangling code blocks.
There are also hipster "forges" like Sourcehut, if that's your jam.
absolutely — removing my dependency on GitHub has actually been a blocker on me releasing code lately, and it’s something I want to tackle when we launch that open source community. if it helps collaboration, I can provide some ultra-janky git hosting on awful.systems with the same service that hosts our infrastructure code, though this’d be just basic git and gitweb with ssh public key auth
Re Perl findall, I used this regex in my "clean" solution which I didn't post because I figure it's more honest to submit what worked, not the smart stuff you found out later.
regex
# find all numerals and number in English from the string $line and put them into the array @spelled my @spelled = ( $line =~ (m/(?=(\d{1}|one|two|three|four|five|six|seven|eight|nine))/g );fuck yes scheme. you might have just inspired me to write some Lisp Machine Lisp solutions, since I might need a Lisp Machine codebase to test one of my side projects
I like your condensed solve method, yay for concise code
