Please is a fast, cross-language build system with an emphasis on extensibility and reproducibility.
It provides a consistent command-line interface for building and testing projects regardless of the languages and tools involved.
The software uses hermetic builds, hash-based caching and parallel task execution to minimise unnecessary work. Its declarative build language can be extended with custom rules to automate almost any part of a build or deployment process.
This is free and open source software.
Key Features
- Supports projects using multiple programming languages and toolchains.
- Provides consistent commands for building, testing and running targets.
- Creates hermetic builds with explicitly declared files and environment variables.
- Caches artifacts using hashes of rule inputs rather than modification timestamps.
- Runs independent build tasks concurrently to take advantage of multiple processor cores.
- Supports shared remote caches for distributing build artifacts between systems.
- Offers an extensible declarative build language with imperative programming constructs.
- Allows users to create custom build rules and command-line aliases.
- Supports tab completion for commands, arguments, flags and build labels.
- Can use Linux namespaces to provide additional build isolation.
- Cross-platform support – actively supports Linux, macOS and FreeBSD.
