To begin, check out the website.
Read the blog or the changelog to learn about new features.
You can install Pomsky by...
- downloading a pre-built binary
- using the shell or PowerShell installer
- using the Windows msi installer
- installing the
@pomsky-lang/cliNPM module globally - installing the
pomsky-binAUR package
See the releases page for instructions.
Ensure you have a recent Rust toolchain installed. Instructions for how to install Rust can be found here. Then run
cargo install pomsky-binPomsky is currently compatible with PCRE, JavaScript, Java, .NET, Python, Ruby, Rust, and RE2. The regex flavor must be specified during compilation, so Pomsky can ensure that the produced regex works as desired on the targeted regex engine.
Note: You should enable Unicode support in your regex engine, if it isn't enabled by default. This is explained here.
There are a few situations where Pomsky expressions are not portable, explained here.
Never compile or execute an untrusted Pomsky expression on your critical infrastructure. This may make you vulnerable for denial of service attacks, like the Billion Laughs attack.
Pomsky looks for mistakes and displays helpful diagnostics:
- It shows an error if you use a feature not supported by the targeted regex flavor
- It detects syntax errors and shows suggestions on how to resolve them
- It parses backslash escapes (which are not allowed in a Pomsky expression) and explains what to write instead
- It looks for likely mistakes and displays warnings
- It looks for patterns that can be very slow for certain inputs and are susceptible to Denial-of-Service attacks (coming soon)
I wrote an in-depth comparison with similar projects, which you can find here.
