Auto updater included?

[nikivdev]

I was looking for alfred rust crate and this one seemed the best. However I am not sure about how to add auto updating.

This rust library: https://github.com/spamwax/alfred-workflow has it.

I am coming to rust from https://github.com/deanishe/awgo in Go and it has auto updater too.

Does this library have this functionality?

It doesn't currently have built-in functionality for this. I'm happy to accept a PR. I don't think it would be too hard to implement. What I think is hard is implementing an API that will work for most use cases.

Ideas

Here is how I would manage the update checks, then use detach::spawn to spawn an async task (doesn't block UI)

use std::time::{Duration, SystemTime};
use std::fs;
use powerpack::detach;
use powerpack::env;

const UPDATE_INTERVAL: Duration = Duration::from_secs(24 * 60 * 60);

fn check_for_updates() -> Result<()> {
    let cache_dir = env::workflow_cache().unwrap();
    let last_update_file = cache_dir.join(".last-update");

    let check_update = match fs::metadata(&last_update_file) {
        Ok(metadata) => {
            let now = SystemTime::now();
            let then = metadata.modified()?;
            now.duration_since(then)? > UPDATE_INTERVAL
        }
        Err(err) if err.kind() == io::ErrorKind::NotFound => true,
        Err(err) => return Err(err.into()),
    };

    if check_update {
        detach::spawn(|| {
            // check github releases (graphql?, semver compatible?)
            
            // if there is a later one
            //     download latest to cache_dir     
            //     install release (using open?)
            
            fs::File::create(&last_update_file).unwrap();
            
        })?;
    }

    Ok(())
}

Possible crates

• semver crate can be used to handle semver stuff
• curl, reqwest, ureq are all great options for HTTP requests
