Struct Awk 

pub struct Awk { /* private fields */ }

High-level wrapper for compiling and running an AWK script.

This type parses the script once and can be run with different input.

Example

use rawk_core::awk::Awk;

let awk = Awk::new("{ print }");
let output = awk.run(vec!["hello world".into()], None);
assert_eq!(output, vec!["hello world".to_string()]);

Implementations

impl Awk

pub fn new(script: impl Into<String>) -> Self

Parse an AWK script into an executable program.

The script is stored with a static lifetime to keep the AST valid.

pub fn run(&self, input: Vec<String>, filename: Option<String>) -> Vec<String>

Execute the compiled program against the given input lines.

When filename is None, FILENAME defaults to "-".
