Hacking on rust and having fun, while trying to debug this fish issue https://github.com/fish-shell/fish-shell/issues/7944

In this commit https://github.com/fish-shell/fish-shell/commit/7fea321b3e58f5801bf7544d7e73cedbed5221df

I see a tmux test, good example of how to do this; useful idea for my editor-testing scheme.

Side quest meanwhile involves getting neovim config in lua - I wanted to use the clientserver feature to avoid having to do special handling to get the :drop command through to the parent vim in a vim terminal.

Now that fish is moving more to rust (rust overtook c++ in the last 2 weeks) I have renewed interest in that. Here's a tiny grep program from a rust commandline guide:

https://rust-cli.github.io/book/tutorial/impl-draft.html

use clap::Parser;

#[derive(Parser)]
struct Cli {
    /// The pattern to look for
    pattern: String,

    /// The file being searched
    path: std::path::PathBuf,
}


fn main() {
    let args = Cli::parse();
    println!("so you tryna search {} in {}", args.pattern, args.path.display());

    let content = std::fs::read_to_string(&args.path).expect("unable to read file");

    for line in content.lines() {
        if line.contains(&args.pattern) {
            println!("{}", line)
        }
    }
}
