anyhow VS tidy

Depending on your use case, thiserror and/or anyhow.

There is ? as well as the anyhow(https://github.com/dtolnay/anyhow) crate that deals with long nested result chains.

There are crates out there that help you reduce this boiler plate. thiserror is good for creating custom errors and color-eyre or anyhow are good for dynamic errors.

Give anyhow a look.

I've brought anyhow::Result into scope, making error handling super easy to use. We don't need to specify all our Error types. It can automatically convert any errors that implement std::error::Error, which should be all of them. If an error propagates all the way up to main(), we'll get all the info it's captured printed to stdout.

Alternatively, if you've got a lot of error types and you're outside a library (so directly in a binary where you don't plan to reuse code elsewhere) you can use anyhow. This gives you an error type you can basically propagate any other error through. On top of that you can attach context information at every return. It's basically a more complicated Result>.

One approach is to define a separate error type for each crate and then use anyhow, eyre or Box to wrap the error, whever a function can return errors originating in several different crates.

Have you tried anyhow and thiserror for making it as simple as .context("Message") or ? to type-convert and propagate errors up the call stack?

I like the concept of finding where the algorithm is "overly strict". And I appreciate teh creativity coming up with this banana example. However, I think given the goal of my project, I do not want to have to "restrict the passphrase generator to a fixed number of words" or similar restrictions on the generator. In other words, making restrictions on the password generator is not "allowed" (more crassly, I want to make my algorithm "idiot proof").

Currently, Tidy can tell users if their created word list "clears" these "lines". However, there's an open issue discussing the accuracy and necessity of these "lines".

Casual programmer here. I've been gradually working on a command-line tool for working with word lists (like you'd use to make a passphrase) I'm calling Tidy.

I'm calling it Tidy. Would love to know if I'm missing any useful features! Or if anything is not working as promised. It's written in Rust -- I welcome contributions via GitHub!
