Args Extractor

Extracting arguments from a command line (prompt) is much easier than ever !

Classic usage

For this prompt : echo "hello world" | ./your_program arg1 arg2 -i -f file.txt

PromptExtractor will extract :

• program_name : "./your_program"
• content_piped : Some("hello world\n")
• arguments : Some(["arg1", "arg2"])
• parameters: Some({"-i": [], "-f": ["file.txt"]})

use args_extractor::{Prompt, PromptExtractor};

fn main() -> Result<(), String> {
    let prompt = PromptExtractor::extract()?;
    println!("{:?}", prompt);

    // # For your own Configuration building process
    // let config = Config::build(prompt)?;

    Ok(())
}

Mock usage

use args_extractor::{Prompt, PromptExtractor};
use std::vec::IntoIter;

fn string_into_iter(input: &str) -> IntoIter<String> {
    input.split_whitespace().map(String::from).collect::<Vec<String>>().into_iter()
}

fn main() -> Result<(), String> {
    let args = string_into_iter("program.exe arg1 arg2 -i -f file.txt");
    let prompt = PromptExtractor::extract_from(args)?;
    println!("{:?}", prompt);

    // # For your own Configuration building process
    // let config = Config::build(prompt)?;

    Ok(())
