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 — similar to dotenv-linter, datanymizer. It checks for brand 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. Normally, any program that can be utilized by means of terminal instructions falls into this class.


How does it work?

update-informer means that you can mechanically test for brand new variations on sources like and GitHub. is the Rust neighborhood’s crate registry, the principle 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 accessible, replace with this hyperlink.”

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

Rust had the same library, however it hadn’t been maintained for fairly a very long time, it didn’t have GitHub assist, and we weren’t fairly happy with the way it labored. It couldn’t be personalized or modified. So we developed a extra common answer 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 software that units it other than others is GitHub assist, along with It additionally affords the flexibility 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 quite a lot 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 test for a brand new model on, use the UpdateInformer::check_version perform. This perform takes the venture title and present model in addition to test 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 accessible: {}", model);

Additionally, you possibly can take the title and model of the venture from Cargo utilizing surroundings variables:

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

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

Be aware that the primary test 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 test will begin solely after an hour

To test for a brand new model on GitHub (observe that the venture title should include 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

In the mean time, 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 are going to work on enhancing this software and increasing the performance. Sooner or later, we plan to assist all widespread hosts, similar to GitLab and Bitbucket, in addition to add assist for numerous HTTP purchasers 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 — reveals our initiative and understanding of what builders love and want. Attain out to us by way of the shape beneath if it is advisable replace your venture to the most recent variations of the know-how stack!
