Not my site, just sharing a link I saw on HN.

Here's a solution with perl (assuming you don't want to change http/https after the start of ( instead of start of a line):

perl -pe 's/\[[^]]+\]\(\K(?!https?)[^)]+(?=\))/lc $&=~s|%20|-|gr/ge' ip.txt

• e flag allows you to use Perl code in the substitution portion.
• \[[^]]+\]\(\K match square brackets and use \K to mark the start of matching portion (text before that won't be part of $&)
• (?!https?) don't match if http or https is found
• [^)]+(?=\)) match non ) characters and assert that ) is present after those characters
• $&=~s|%20|-|gr change %20 to - for the matching portion found, the r flag is used to return the modified string instead of change $& itself
• lc is a function to change text to lowercase

Memory, Sorrow, and Thorn by Tad Williams

I'm not the site author, just submitting the link.

Not sure which part you need to be logged in to view - I'm seeing links to different articles and exercises and they are all visible without logging (I checked in an incognito window).

Is it regex or sed/awk syntax (or both) that gives you trouble?

I had similar reaction and didn't even try to learn them for years - then I caught the stackoverflow craze of answering CLI questions (and learning from others).

magic is used and studied/understood like science

I haven't read Dungeon Crawler Carl yet, but that should fit your criteria right? Many of the progression fantasy books usually have a magic system with tangible tiers and usually rules are known too.

Cradle by Will Wight and Mage Errant by John Bierce are both complete series and I'd put their magic system as hard. Mage Errant dives deeper into the workings, especially as the main characters are students and one of their teachers is especially knowledgeable. Arcane Ascension by Andrew Rowe is another series with such academy focus and a progression magic system.

Finished The Magicians of Caprona (Chrestomanci, #4) by Diana Wynne Jones earlier today. It had the usual whimsical charm but the characters and plot took a while to get used to.

Haven't decided yet what I'll read next, but thinking of starting the "Harper Hall" trilogy. I read Dragonriders of Pern a few years back, don't remember much. Will be interesting to see if I'd enjoy Harper Hall, which IIRC was said to be more on the cozy side.

I use GVim for coding and text editing in general.

Programming wise, CLI tools (grep, sed, awk, sort, head, etc) are enough for most of my tasks. I've written a few Python TUI projects (uses Textual framework) but these are around 300-400 lines, so Vim is more than enough for my purposes. Don't even need any plugins.

That depends on the regex flavor. Some of them have full support for variable length lookbehinds, for example JavaScript and third-party regex module for Python.

The book is a 2023 Hugo finalist in the "Best Novel" category and the author is part of the "Astounding Award for Best New Writer" (https://file770.com/2023-hugo-finalists-2/)

It was one of my best reads last year and so happy that it popularized the cozy fantasy subgenre.
