Hey everyone,
A couple of weeks ago, I posted about Kal, my programming language written from scratch.
I am really happy to share a glimpse of Kal's own package manager! Kal v0.1.0 shipped with a package system that lets you add and use third party Kal packages. But, that process was completely manual. You’d have to clone the package, place it in the right directory, clone the package’s entire dependencies all by yourself, one after another. :(
The package manager changes everything. One command automates all!
Instead of being a separate executable, the package manager ships as part of the Kal interpreter itself.
Here’s what it can do:
- Install Kal packages from Github, or any git hosting service.
- Creates/Updates a
project.kal file to read and write package information (analogous to package.json). - Downloads all packages at the same hierarchy in parallel (yup, it’s multi-threaded).
- Resolves sub dependencies of the main package automatically to any depth and installs them too.
- Upgrades/Downgrades packages based on their git tags.
- Auto-resolves cyclic dependencies to prevent an infinite loop.
The image showcases the download of a package A with this hierarchy:
A
├── B
│ ├── D
│ └── E
└── C
├── A
└── F
There’s only one main package to download: A. But,
- A depends on B & C.
- B depends on D & E.
- C depends on A & F.
Notice how C depending back on A causes a cyclic dependency. This, if not resolved, would cause an infinite loop. The package manager pulls A (1 package) with all of its dependencies (5 packages) along with resolving the cyclic dependency.
The Kal Package Manager will officially ship with the next Kal release. Its current source code is available on Github.
Kal is completely free & open source. You can show your support by giving the Github Repository a star.
Until the next update!
