Such old urban places would just be car-free in the Netherlands (sometimes with limited access for delivery and emergency vehicles), a trend fortunately becoming popular in other European cities now. The “urban” in the title is a bit mislea

I would love to see the diff between the hand-rolled recursive-descent parser and the ANTLR syntax! I certainly feel the amount of boilerplate in my hand-rolled recursive-descent parser is manageable. Of course it's not as succinct as

Yeah, ultimately there's an element of personal taste at play. The authoritative tone of "how to write ..." is meant in jest, but obviously by doing that I risk being misunderstood. A more accurate title would be "how I

Did you set your login shell to Elvish? Vim unfortunately relies on your shell being a POSIX shell, but you can fix that with "set shell=/bin/sh" in your rc file.

Right, I may have forgot to mention that lexerless parsers are somewhat unusual. I didn't have much time in the talk to go into the reason, so here it is: - You'll need a more complex lexer to parse a shell-like syntax. For exampl

That seems to be a bad translation, the original text means something like “sharpen something fully and it won’t last so long” (presumably due to it being more brittle). The text (like the rest of Tao Te Ching) is pretty vague and doesn’t a

Oh, I definitely didn't read your entire comment as negative, just the way you used "elvishism". Elvish definitely has its quirks! But I hope you'll find it a compelling package overall :)

> Elvish visibly leans into this to try to have a consistent syntax. Sometimes the similarities go deeper, too; IIRC, its number types are inspired by Scheme, for example. Yes! Similarity to Lisp is very much a deliberate design choice a

It wasn't directly borrowed from any other language ( https://news.ycombinator.com/item?id=40317577 ) but there's definitely something nice about the syntax that causes multiple languages to use it. Elvish predates

Thank you for the compliment!

I take your comment as implying that https://elv.sh is nice, clean and elegant, and thank you for the compliment :) I can't speak for other people, but I made it on my own and don't have any formal training in design.

Yes! I haven't been using it as my daily driver for almost 10 years now. There are detailed instructions on how to get it and use it as your default shell in https://elv.sh/get/ .

It was inspired by browsers' location bar - the name (location mode) and the default ^L binding are a nod to browsers too. These days browsers will often suggest results from search engines but back then (at least in Firefox?) it was j
