Requirements

This repository requires Rust language/compiler to build from source

As of last update to this ReadMe file, the recommended method of installing Rust is via the installer script...

Bash curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Quick Start

This repository is a Rust library, define it as a dependency within a project Cargo.toml file...

Cargo.toml (snip)

toml [dependencies] version_operators = "0.0.1"

Check Rust -- Doc -- Specifying Dependencies for details about defining dependencies.

Then include within a source file via use statement...

src/main.rs (snip)

Rust use version_operators::Version;

Usage

src/main.rs (example)

```Rust use version_operators::Version;

fn main() { let version = Version::from_str("1.14.3");

let expected = vec![1, 14, 3];

assert_eq!(version.to_vector(), expected);

} ```

Check the examples/ directory of this repository for more detailed examples of how this project may be utilized within other applications, use cargo run --example <name> to execute, eg...

examples/version-compare.rs

```Bash cargo run --example version-compare '1.14.3' '-lt' '1.14.4'

> true

cargo run --example version-compare '1.14.3' '==' '1.14.4'

> false

```

examples/version-math.rs

```Bash cargo run --example version-math '1.14.4' '-add' '1.14.3'

> [2, 28, 7]

cargo run --example version-math '1.14.4' '-sub' '1.14.3'

> [0, 0, 1]

```

Notes

Until version 0.1.0; methods, data structure properties, and implementation name(s) may have names and/or behavior change!

This repository may not be feature complete and/or fully functional, Pull Requests that add features or fix bugs are certainly welcomed.

Currently math and comparison operators start with the most significant bits of each version. This means that when operating on versions of unequal length it may be useful to zero-pad the shorter version...

```Rust use version_operators::Version;

fn main() { let versionone = Version.fromstr("1.14.3"); let versioninc = Version.fromstr("0.0.1"); let newversion = versionone + version_inc;

assert_eq!(new_version.to_vector(), vec![1, 14, 4]);

} ```

Check source code of examples/version-increment.rs for an example of targeting a portion of a version to increment...

```Bash cargo run --example version-increment '1.14.3' '1'

> [1, 15, 3]

```

Options for contributing to version and rust-utilities

Forking

Start making a Fork of this repository to an account that you have write permissions for.

• Add remote for fork URL. The URL syntax is git@github.com:<NAME>/<REPO>.git...

```Bash cd ~/git/hub/rust-utilities/version_operators

git remote add fork git@github.com:/version_operators.git ```

• Test changes via cargo...

Bash cargo test

• Commit your changes and push to your fork, eg. to fix an issue...

```Bash cd ~/git/hub/rust-utilities/version_operators

git commit -F- <<'EOF' :bug: Fixes #42 Issue

Edits

• <SCRIPT-NAME> script, fixes some bug reported in issue EOF

git push fork main ```

Note, the -u option may be used to set fork as the default remote, eg. git push -u fork main however, this will also default the fork remote for pulling from too! Meaning that pulling updates from origin must be done explicitly, eg. git pull origin main

• Then on GitHub submit a Pull Request through the Web-UI, the URL syntax is https://github.com/<NAME>/<REPO>/pull/new/<BRANCH>

Note; to decrease the chances of your Pull Request needing modifications before being accepted, please check the dot-github repository for detailed contributing guidelines.
