bistro is anOCaml library to build and runcomputations represented by a collection of interdependent scripts, asis often found in applied research (especially computationalbiology).

Features:

• build complex and composable workflows declaratively
• simple and lightweight wrapping of new components
• resume-on-failure: if something fails, fix it and the workflow willrestart from where it stopped
• distributed workflow execution
• development-friendly: when a script is modified, bistroautomatically finds out what needs to be recomputed
• automatic naming of generated files
• static typing: detect file format errors at compile time!

The library provides a datatype to represent scripts (includingmetadata and dependencies), an engine to run workflows and astandard library providing components for popular tools (althoughmostly related to computational biology and unix for now).

Questions, suggestions or contributions are welcome, please file anissue as needed.

Amanualis available, but feel free to file issues if something is unclear ormissing. There is also agenerated API documentation.

Detailed instructions are available in themanual. Ina nutshell,bistro can be installed usingopam. You need a recent (at least 4.03.0)installation of OCaml. Once this is done, simply type
