bistro is an OCaml library to build and run
computations represented by a collection of interdependent scripts, as
is often found in applied research (especially computational
biology).

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 will
  restart from where it stopped

• distributed workflow execution

• development-friendly: when a script is modified, bistro
  automatically 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 (including
metadata and dependencies), an engine to run workflows and a
standard library providing components for popular tools (although
mostly related to computational biology and unix for now).

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

Documentation

A
manual
is available, but feel free to file issues if something is unclear or
missing. There is also a
generated API documentation.

Installation

Detailed instructions are available in the
manual. In
a nutshell, bistro can be installed using
opam. You need a recent (at least 4.03.0)
installation of OCaml. Once this is done, simply type

opam install bistro

to install the library, or:

opam pin add -y bistro --dev-repo

to get the current development version.
