Pants is a scalable build system for monorepos: codebases containing multiple projects, often using multiple programming languages and frameworks, in a single unified code repository.
Pants installs, orchestrates and runs dozens of standard underlying tools – compilers, code generators, dependency resolvers, test runners, linters, formatters, packagers, REPLs and more – composing them into a single stable, hermetic toolchain, and speeding up your workflows via caching and concurrency.
Pants is designed to be easy to adopt, use, and extend. It doesn’t require you to refactor your codebase or to create and maintain massive amounts of build metadata. You invoke it directly on source files and directories, so it doesn’t require users to adopt a new conceptual model.
It’s currently focused on Python, Go, Java, Scala, Kotlin, Shell, and Docker, with support for other languages and frameworks coming soon.
This is free and open source software
Features include:
- Explicit dependency modeling using static analysis instead of handwritten metadata.
- Fine-grained invalidation.
- Shared result caching.
- Concurrent and remote execution.
- Unified interface for multiple tools and languages.
- Extensibility and customizability via a plugin API that uses idiomatic async Python 3, in case you need any customizations.
- Code introspection features.
- Requires very minimal BUILD file metadata/boilerplate. It uses a combination of static analysis and sensible defaults to infer most of that information on the fly.
