pomsky VS validator

I started with JS, and my first step was to write a simple script that checks if a regex is valid. I can call this script from Rust, but there's a problem: Starting a nodejs process takes about 100ms, which is not acceptable, especially for fuzzing.

I noticed this when a test case of a parser I wrote failed in CI on Windows. I then learned that the default stack size on Windows is only 1 MiB whereas its 8 MiB on Linux if I remember correctly. The parser has a hard-coded recursion limit to prevent stack overflows, which is currently set to 128. However, this limit is lower than necessary on Linux, and might still be too high for some platforms (embedded?)

I was informed that Rulex is a registered trademark and I'm not allowed to use the name for my project. A lawyer contacted me and gave me a week to rename the project, so I have to come up with a different name :(

In the other discussion, there's also a link to Rulex, which has similar goals but is more concise. Also claims to compile to multiple regex dialects.

Something similar happened to me a week ago. Someone emailed me that they found panics in rulex, and then created a PR to fix them. They even explained to me how to create a security advisory on GitHub because the panics could be used to DoS someone. It was very helpful.

Sorry for not being more specific. Since this is a parser, the span points into the text file that is being parsed, so it's not that relevant for most libraries. Here is the parser, it uses nom parser combinators. Unfortunately, and adding the spans to the errors involves some boilerplate.

I welcome contributions for rulex. It's a medium-sized project that should be fairly easy to understand, and has some "good first issues" :)

(That's how certain kinds of extensibility work in the validator crate. You just impl a method and validator won't care where it comes from as long as it's in scope because it's built using declarative macros.)

The rust proc macro system is my absolute favorite feature of the language. One of my other favorite libraries is https://github.com/Keats/validator

Hi! I'm happy to announce the release of garde. In summary, this is a rewrite of the validator crate.

Validator : Macros 1.1 custom derive to simplify struct validation inspired by marshmallow and Django validators

https://github.com/Keats/validator needs some help, it's a validation library that easily plugs into Web Development.

(The validate attribute is from the validator crate.)

Would love to use it in https://github.com/Keats/validator when it's ready!

Actually, /u/mehcode just reminded me that this exists: https://github.com/Keats/validator
