| 05:21 | <&jerith> | AoC day 2 done. |
| 05:22 | <&jerith> | (My brain decided 06h30 was an entirely reasonable time to be awake (it is not) so I was around for the unlock.) |
| 05:34 | <&McMartin> | Heh. |
| 05:34 | <&McMartin> | My Rust parsers leave something to be desired |
| 05:38 | <&jerith> | I used `nom` for parsing back in 2018. |
| 05:41 | <&jerith> | I can't remember if that's before or after the update that cleaned up its internal use of macros. |
| 05:42 | <&jerith> | Either way, I always end up with a "parser tools" module of some kind full of conveniences. In the Rust/nom case, this involved a lot of little wrapper macros for common things. |
| 05:43 | <&jerith> | Also, I see there's a pending invite to you for access to my (private) adventofcode-2018 github repo if you want to see what I did there. :-) |
| 05:45 | <&McMartin> | I looked at it years ago and decided I didn't want to take a framework wholesale like that. |
| 05:46 | <&McMartin> | And yeah, this involved things like heavy use of split().collect() and then doing nonsense like chars() iteration to make sure I can count indices into a string. |
| 05:46 | <&McMartin> | I would probably have made more sense to turn strings into Vec<u8>s and then get random access |
| 05:47 | <&jerith> | Maybe #aocspoilers for details involving particular problems? |
| 05:47 | <&jerith> | Although you managed to skirt around those without actually hitting them. ;-) |
| 05:49 | <&jerith> | I decided early on (maybe even as early as 2016) that I was going to use a parsing library as one of my very few external deps. |
| 05:53 | <&jerith> | (On the basis that otherwise I'd be reinventing a lot of stuff, and parsing input is not the interesting part of the problem anyway.) |
| 06:32 | <&McMartin> | I actually appreciate the low-grade hurly-burly of file access and string manipulation for this. |
| 06:33 | <&McMartin> | It's the kind of byte-level nonsense that Rust is supposed to be able to do as effectively as C/C++/etc. |
| 06:33 | <&McMartin> | (Though it turns out in practice, the rigid format of the input files gives C some comically unfair advantages) |

| 11:15 | <~Vorntastic> | A series of increasingly challenging programming challenges running through December until Christmas |

| 11:56 | < Yossarian> | Okay, another newb question... I haven't written any real code in a long time and let alone on Linux. It's about documentation with libraries or libdev entries in repo... |
| 11:57 | | Kindamoody is now known as Kindamoody|afk |
| 11:57 | < Yossarian> | Usually, if you compile one, you ought to get manpages or something, yes? |

| 12:05 | < Yossarian> | I'm looking for the documenation of fucntions for codec2 and I can't find it. |
| 12:06 | < Yossarian> | or curses |
| 12:07 | < Yossarian> | /usr/share/doc is looking light, too |
| 12:11 | < Yossarian> | or is codec2 so simple they don't provide these things? https://github.com/drowe67/codec2/blob/master/src/codec2.h |

| 13:59 | <&[R]> | Yossarian: did you compile it yourself or get it from a debianoid repo? |
| 14:00 | <&[R]> | Because debian likes to slice every package it can into as many parts as it can. So you might be missing -doc or -man packages |
| 14:01 | <&[R]> | `man ncurses` will bring up ncurses documentation (It's on disc0 if you don't have them locally) |
