a extremely customizable Rust library for CLI apps by Evrone

update-informer is a library created primarily for CLI instruments which might be written in Rust — comparable 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. Usually, any program that can be utilized by way of terminal instructions falls into this class.


How does it work?

update-informer lets you routinely verify for brand spanking new variations on assets like Crates.io and GitHub. Crates.io is the Rust neighborhood’s crate registry, the principle useful resource the place all initiatives, libraries, and so on. are saved.

Once 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 offered, replace with this hyperlink.”

There are a variety of initiatives with comparable 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 well-liked.

Rust had an identical library, nevertheless it hadn’t been maintained for fairly a very long time, it didn’t have GitHub assist, and we weren’t fairly glad with the way it labored. It couldn’t be personalized or modified. So we developed a extra common resolution for Rust neighborhood that may be personalized in each potential means.

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 assist, along with Crates.io. It additionally presents the flexibility to configure the frequency of checks (you’ll be able to 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 loads of dependencies, leading to code base will increase, compilation time will increase, and so on.

The consequence seems like this:


Add update-informer to Cargo.toml:

update-informer = "0.2.0"

To verify for a brand new model on Crates.io, use the UpdateInformer::check_version perform. This perform takes the venture 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", Length::from_secs(60 * 60 * 24));
if let Okay(Some(model)) = informer.check_version() {
    println!("New model is offered: {}", model);

Additionally, you’ll be able to take the identify and model of the venture from Cargo utilizing surroundings 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, Length::from_secs(60 * 60 * 24)).check_version();

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

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

const EVERY_HOUR: Length = Length::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 (word that the venture identify should comprise the proprietor):

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

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

Plans for the long run

For the time being, the v0.2.0 model of the update-informer has been launched. If there may be curiosity from the neighborhood or requests for enhancements, then in fact we’ll work on bettering this instrument and increasing the performance. Sooner or later, we plan to assist all well-liked hosts, comparable to GitLab and Bitbucket, in addition to add assist for varied HTTP shoppers to cut back dependencies. Test the venture’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 — exhibits our initiative and understanding of what builders love and wish. Attain out to us through the shape beneath if you want to replace your venture to the newest variations of the know-how stack!
