regen is a Rust library and command-line tool for generating all strings matching a regular expression.
The detailed module documentation, including code examples for all features, can be found at https://docs.rs/regen.
Usage: regen [options] <pattern>
Options:
-m, --max-length LENGTH
The maximum number of elements (characters or bytes)
in the generated strings
-c, --count Print out the count of generated strings instead of
the strings themselves
To use the regen library add the following to your Cargo.toml:
[dependencies]
regen = "0.1"A quickstart example:
// Uncomment the following when using the older Rust 2015 edition:
// extern crate regen;
use regen::{Generator, Result};
fn main() -> Result<()> {
let mut out = Vec::new();
let mut gen = Generator::new("[a-z]{2}")?;
while gen.append_next(&mut out).is_some() {
// Process 'out'...
// and possibly out.clear() depending on the scenario.
}
Ok(())
