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 have been 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 means of terminal instructions falls into this class.


How does it work?

update-informer means that you can mechanically examine for brand spanking new variations on assets like and GitHub. is the Rust group’s crate registry, the primary useful resource the place all tasks, libraries, and many others. 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 accessible, replace with this hyperlink.”

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

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 resolution for Rust group that may be custom-made in each doable manner.

update-informer generates a notification within the code throughout program begin (within the logs). One of many key options of this device that units it aside from others is GitHub help, along with It additionally gives 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 carry lots of dependencies, leading to code base will increase, compilation time will increase, and many others.

The outcome appears like this:



Add update-informer to Cargo.toml:

update-informer = "0.2.0"

To examine for a brand new model on, use the UpdateInformer::check_version operate. This operate takes the mission title and present model in addition to examine 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’ll be able to take the title and model of the mission from Cargo utilizing atmosphere 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();

Word that the primary examine 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 examine will begin solely after an hour

To examine for a brand new model on GitHub (notice that the mission 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 longer term

In the intervening time, the v0.2.0 model of the update-informer has been launched. If there’s curiosity from the group or requests for enhancements, then in fact we are going to work on bettering this device and increasing the performance. Sooner or later, we plan to help all common hosts, akin to GitLab and Bitbucket, in addition to add help for varied HTTP shoppers to cut back dependencies. Test the mission’s GitHub and ship us pull requests!

Our work on open-source tasks — and the truth that each month we select a number of OSS tasks to sponsor — exhibits our initiative and understanding of what builders love and want. Attain out to us through the shape under if it is advisable to replace your mission to the newest variations of the expertise stack!
