[2022 day 19] after trying ever day for the last 11 days, nothing seems to work
I've tried this, didn't seem to help me much. I think this was the code

I'm really proud of solving this year, some close calls for giving up in there for sure! 18, 19, and 24 threw me for a loop. Thanks topaz for another great year 💙

Day 14 2019
For part 2, I have one hint for you. I never could quite figure out how to handle spares and use them correctly. So I just ended up calculating decimals. As in, it requires 2.7 of material X. And then figuring out how to round later. Maybe this helps. My repo is https://github.com/yspreen/adventofcode

[2019 Day 7] Part two: Examples work, puzzle input does not
Okay, this bug hid extremely well. My extraction of opcodes from the input was faulty, and apparently only now did some edge-case catch that! Incredible. This is the fix commit: https://github.com/yspreen/adventofcode/commit/5edfa126b7176f2fa7776fe15eb4b4eff1386bb2

Planespotting with Rust: using nom to parse ADS-B messages
Just in case you are not familiar with nom, it is a parser combinator written in Rust. The most basic thing you can do with it is import one of its parsing functions, give it some byte or string input and then get a Result as output with the parsed value and the rest of the input or an error if the parser failed. tag for example is used to recognize literal character/byte sequences.

Show HN: Rust nom parsing Starcraft2 Replays into Arrow for Polars data analysis
I may be the only one not familiar, but nom refers to https://github.com/rust-bakery/nom which looks like a pretty handy way to parse binary data in Rust.
-
Is this a good way to free up some memory?
Lots of people use nom for their parsing needs, but that's not the only game in town and there other options.
-
What is the state of the art for creating domain-specific languages (DSLs) with Rust?
As much as I love nom as well as other parser combinator libraries, regex-based parsers, BNF/EBNF-based parsers, etc. I always end up going back to plain old text-based char-by-char scanners.

What's everyone working on this week (22/2023)?
I am using nom / nom_locate to build the parser side because I've done a handful of other projects with it, and I plan to use tower-lsp to hook up the language server side.

Tokenizing
Look into a parsing library such as https://github.com/rust-bakery/nom

Something like pydantic but for just strings?
If we were in /r/learnrust I'd have recommended the nom crate for this.

lua bytecode parser written in rust
Thanks to the flexibility of [nom](https://github.com/rust-bakery/nom), it is very easy to write your own parser in rust, read [this article](https://github.com/metaworm/luac-parser-rs/wiki/Write-custom-luac-parser) to learn how to write a luac parser

Should I revisit my choice to use nom?
I've been working on an assembler and right now it uses nom. While nom isn't great for error messages, good error messages will be important for this particular assembler (current code), so I've been attempting to use the methods described by Eyal Kalderon in Error recovery with parser combinators (using nom).
