a extremely customizable Rust library for CLI apps by Evrone


update-informer is a library created primarily for CLI instruments which can be written in Rust — akin to dotenv-linter, datanymizer. It checks for brand spanking new variations which were launched and sends notifications when an replace is discovered. update-informer was developed by an open-source fanatic Mikhail Grachev.

CLI stands for Command Line Interface — a command-line program that reads the instructions you enter and performs the requested motion. Typically, any program that can be utilized by way of terminal instructions falls into this class.


How does it work?

update-informer permits you to mechanically verify for brand spanking new variations on assets like and GitHub. is the Rust group’s crate registry, the primary useful resource the place all initiatives, libraries, and so on. are saved.

Whenever you add the update-informer library in your CLI utility, which runs within the console, it periodically (for instance, as soon as a day) checks to see if a brand new model has been launched. If one is out, then update-informer sends a message to the console like, “A brand new launch is obtainable, replace with this hyperlink.”

There are a selection of initiatives with related instruments. For instance, GitHub CLI can convey GitHub to your terminal. Its performance comes out of the field, and you’ll work with points, pull requests, checks, releases, and extra. There may be additionally a library like this in Javascript, which could be very fashionable.

Rust had an identical library, nevertheless it hadn’t been maintained for fairly a very long time, it didn’t have GitHub help, and we weren’t fairly happy with the way it labored. It couldn’t be custom-made or modified. So we developed a extra common answer for Rust group that may be custom-made in each doable approach.

update-informer generates a notification within the code throughout program begin (within the logs). One of many key options of this instrument that units it other than others is GitHub help, along with It additionally provides the power to configure the frequency of checks (you possibly can specify any size of time, even checking each single second) and has the minimal variety of dependencies — solely ureq, semver and serde. This is essential, since third-party options fairly often convey a number of dependencies, leading to code base will increase, compilation time will increase, and so on.

The end result appears like this:



Add update-informer to Cargo.toml:

update-informer = "0.2.0"

To verify for a brand new model on, use the UpdateInformer::check_version operate. This operate takes the mission identify and present model in addition to verify interval:

use update_informer::{registry::Crates, Test, UpdateInformer};

let informer = UpdateInformer::new(Crates, "repo", "0.1.0", Period::from_secs(60 * 60 * 24));
if let Okay(Some(model)) = informer.check_version() {
    println!("New model is obtainable: {}", model);

Additionally, you possibly can take the identify and model of the mission from Cargo utilizing atmosphere variables:

use update_informer::{registry::Crates, Test, UpdateInformer};

let identify = env!("CARGO_PKG_NAME");
let model = env!("CARGO_PKG_VERSION");
UpdateInformer::new(Crates, identify, model, Period::from_secs(60 * 60 * 24)).check_version();

Notice that the primary verify will begin solely after the interval has expired:

use update_informer::{registry::Crates, Test, UpdateInformer};

const EVERY_HOUR: Period = Period::from_secs(60 * 60);

let informer = UpdateInformer::new(Crates, "repo", "0.1.0", EVERY_HOUR);
informer.check_version(); // The verify will begin solely after an hour

To verify for a brand new model on GitHub (be aware that the mission identify should comprise the proprietor):

use update_informer::{registry::GitHub, Test, UpdateInformer};

let informer = UpdateInformer::new(GitHub, "proprietor/repo", "0.1.0", Period::from_secs(60 * 60 * 24));

Plans for the long run

In the meanwhile, the v0.2.0 model of the update-informer has been launched. If there’s curiosity from the group or requests for enhancements, then after all we’ll work on enhancing this instrument and increasing the performance. Sooner or later, we plan to help all fashionable hosts, akin to GitLab and Bitbucket, in addition to add help for varied HTTP purchasers to scale back dependencies. Test the mission’s GitHub and ship us pull requests!

Our work on open-source initiatives — and the truth that each month we select a number of OSS initiatives to sponsor — reveals our initiative and understanding of what builders love and wish. Attain out to us through the shape beneath if you must replace your mission to the most recent variations of the expertise stack!
