Hi,

First, thanks for doing the video series, I'm learning a lot!

When I started doing it (before I found your series), I knew I needed a parser, so did some Googling, and it seems that nom and pest are two of the more popular crates.

You have been doing a lot of nom, so I was wondering if you'd be willing to have a go with pest?

Cheers!

Hi,

Nice repository and great learning materials, while browsing the Repository I saw that you're including the AoC inputs in the code.

It is explicitly asked not to do this by the the creator here.

Best Regards

Hi!

Sorry to ask a question here but I'm become nuts.
Disclaimer: I'm a beginner with Rust.

In your example here you unwrap (it's the solution which work for me) and I need to do the same but I want to use ? operator instead but the compiler tell me bad things and I don't known how to fix that. So I found your github and... you unwrap too so I don't know how to handle the error because I want to do a library so I need to handle error.

My goal is to parse a string slice like 04:53:33,324 or 2:3:44,123 which represent hour:minute:second,millisecond (my end goal is to parse a srt file).

If you have some time for that, I will really appreciate your help and some explaination because nom is awesome but it's hard too.

#[derive(Debug)]
struct Time {
    hour: u8,
    // minute: u8,
    // second: u8,
    // millisecond: u16,
}

impl Time {
    fn parse(input: &str) -> IResult<&str, Self> {
        let (input, hour) = digit1(input)?;
        println!("{:#?}", hour);
        Ok((
            input,
            Time {
                hour: hour.parse::<u8>().unwrap(),
            },
        ))
    }
}

I want to handle the error if the input is alphabetic for example.

Thx.

I got stuck on part two for this problem, so I went to use your code as a reference. Updated my logic to match, which passes all the sample cases, however it does not work for my input data.

I then pulled your exact code and ran it on my input data and it does not work. I'm having trouble finding what the specific edge case is, but here is my input data https://gist.github.com/dmaahs2017/0f711278cd6a32e403c010a520f99285. The answer is not 444, answer too high.

I think this means there may be bug in your day10 part 2 solution, but you happened to get lucky with the input data not containing a particular edge case.

When trying to run the "just create day-01" command I got an error stating :

/usr/bin/env: ‘cargo +nightly -Zscript’: No such file or directory
/usr/bin/env: use -[v]S to pass options in shebang lines

Indeed, changing the line to

#!/usr/bin/env -S cargo +nightly -Zscript 

allowed it to work on my system.

Hi, it looks like a bug

3 moves between 0 and 4:
1, 2, -2, -3, 0, 3, 4

-2 moves between 4 and 1:
1, 2, -3, 0, 3, 4, -2

if you add a check for 0 in the added variable and insert current at the end of the list, then everything will work too and the output from the example will match
