Batteries Included
A community-maintained foundation library for OCaml projects, providing a comprehensive standard library with consistent APIs.
What is Batteries Included?
OCaml Batteries Included is a community-maintained foundation library that extends the OCaml standard library with additional functionality and improved organization. It provides a comprehensive, consistent set of tools that OCaml developers can rely on across different installations, aiming to solve the problem of a fragmented or insufficient standard library.
OCaml developers seeking a more extensive and uniformly organized standard library for their projects, particularly those migrating from ExtLib or needing a reliable, installation-agnostic foundation.
Developers choose Batteries for its unified module hierarchy and consistent API design, which simplifies library usage and documentation access compared to mixing independent libraries. It also offers direct compatibility with ExtLib, easing migration for existing projects.

Use Cases
Best For
- Extending the OCaml standard library with missing utilities and functionality.
- Organizing OCaml libraries into a coherent, well-documented module hierarchy.
- Migrating projects from ExtLib to a more comprehensive foundation library.
- Ensuring consistent API design across different OCaml libraries.
- Accessing centralized documentation for a standard set of OCaml libraries.
- Building OCaml applications that require a reliable, community-maintained foundation across various installations.
Not Ideal For
- Projects heavily dependent on ExtLib's Unzip module, which Batteries currently lacks.
- Teams already invested in Jane Street's Core or Base libraries, which offer different design philosophies and might not integrate seamlessly.
- Minimalist OCaml applications where the extra dependencies and features of Batteries are unnecessary overhead.
- Performance-critical systems requiring minimal abstraction layers, as Batteries' extended functionality might introduce slight overhead.
Pros & Cons
Pros
Adds missing utilities and functionality to OCaml's core, providing a more comprehensive toolset for common development tasks.
Organizes libraries into a coherent module hierarchy with a single source of documentation, simplifying learning and reference, as highlighted in the README.
Ensures uniform interfaces across libraries, reducing cognitive load and improving code maintainability through standardized patterns.
Offers direct compatibility by allowing simple package swaps and module openings, easing transition for existing ExtLib users, per the README's guidance.
Cons
Lacks certain ExtLib modules like Unzip, which can hinder full migration for projects reliant on those features, as admitted in the compatibility note.
Requires multiple optional libraries for full functionality and testing, such as OUnit and qtest, adding steps to installation and configuration.
As a community-maintained project, updates and bug fixes may be slower compared to commercially backed alternatives, potentially affecting long-term support.
