regen

regen is a Rust library and command-line tool for generating all strings matching a regular expression.

Documentation

The detailed module documentation, including code examples for all features, can be found at https://docs.rs/regen.

Command-line tool usage

``` Usage: regen [options]

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 ```

Library usage

To use the regen library add the following to your Cargo.toml:

toml [dependencies] regen = "0.1"

A quickstart example:

```rust // 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.appendnext(&mut out).issome() { // Process 'out'... // and possibly out.clear() depending on the scenario. }

Ok(())

}

```
