How to call from Rust into JS, Java, C#, Ruby and Python?
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.

How do you guard against stack overflows
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 have to rename Rulex
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 :(

Melody 0.18 (a sane alternative to regular expressions)
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.

Fuzzing rust-minidump at Mozilla for Embarrassment and Crashes – Part 2
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.

Where would you put Error enums?
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.

Any active open source repos built using Rust that need development ?
I welcome contributions for rulex. It's a medium-sized project that should be fairly easy to understand, and has some "good first issues" :)

Regex generator
Sounds like you're looking for something like grex. Mind you, this does not save you from learning about regular expressions. It‘s more of a supporting tool.

RegExr: Learn, Build and Test Regex
If I understood what you mean, then yes, I bout one https://regex.help/ (powered by https://github.com/pemistahl/grex doing the heavy lifting).
- grex is a library as well as a command-line utility that is meant to simplify the often complicated and tedious task of creating regular expressions. It does so by automatically generating a single regular expression from user-provided test cases.
What are some alternatives?
When comparing pomsky and grex you can also consider the following projects:
melody - Melody is a language that compiles to regular expressions and aims to be more readable and maintainable
yaegi - Yaegi is Another Elegant Go Interpreter
regex-automata - A low level regular expression library that uses deterministic finite automata.
rust-csv - A CSV parser for Rust, with Serde support.
kleenexp - modern regular expression syntax everywhere with a painless upgrade path
codetour - VS Code extension that allows you to record and play back guided tours of codebases, directly within the editor.
taffy - A high performance rust-powered UI layout library
parallel-disk-usage - Highly parallelized, blazing fast directory tree analyzer
regex - An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.
percol - adds flavor of interactive filtering to the traditional pipe concept of UNIX shell
oil - Oils is our upgrade path from bash to a better language and runtime. It's also for Python and JavaScript users who avoid shell!
rust-iptables - Rust bindings for iptables
