A rewrite of the Serpent OS tooling in Rust, enabling a robust implementation befitting Serpent and Solus

We will initially focus on moss and stone (library), restoring parity while focusing on some key areas

• Version agnostic read APIs
• Decoupled repository indices with support for format upgrades
• Asynchronous I/O (specifically fetches)
• Memory consumption + safety
• Upgrade of installations

When the tooling is at a point exceeding the functionality of our first version, focus will shift to the build infrastructure as well as the Rust version of boulder (.stone build tooling).

It is recommended to use an up to date version of Rust via rustup.

Progress:

• Read support for .stone
• Repository manipulation
• Plugin system for layered graph of dependencies
• Search support
• Transactions
• Installation support
• Removal support
• sync support (See: serpent-os#73 (comment))
• Trigger integration (usysconf-rs)
• GC / cleanups of latent states
• Features (previously: Subscriptions)

$ cargo test

$ cargo build -p moss
$ cargo run -p moss -- $args

Remember to use the -D sosroot argument to specify a root directory, otherwise moss will happily eat your operating system.

cargo build --release

# create the sosroot/ directory
mkdir -pv sosroot/

# Add the volatile repo
./target/release/moss -D sosroot/ repo add volatile https://dev.serpentos.com/volatile/x86_64/stone.index

# List packages
./target/release/moss -D sosroot/ list available

# Install something
./target/release/moss -D sosroot/ install systemd bash libx11-32bit

Please ensure all tests are running locally without issue:

$ cargo test

# Prior to commiting a change:
$ cargo fmt

# Prior to pushing anything, check:
$ cargo clippy

moss-rs is available under the terms of the MPL-2.0
