I am happy to announce the release of OASIS v0.4.3.

Logo OASIS small

OASIS is a tool to help OCaml developers to integrate configure, build and install systems in their projects. It should help to create standard entry points in the source code build system, allowing external tools to analyse projects easily.

This tool is freely inspired by Cabal which is the same kind of tool for Haskell.

You can find the new release here and the changelog here. More information about OASIS in general on the OASIS website.

Here is a quick summary of the important changes:

  • Added -remove switch to the setup-clean subcommand designed to remove unaltered generated files completely, rather than simply emptying their OASIS section.
  • Translate path of ocamlfind on Windows to be bash/win32 friendly.
  • Description is now parsed in a more structured text (para/verbatim).


  • stdfiles_markdown (alpha): set default extension of StdFiles (AUTHORS, INSTALL, README) tp be '.md'. Use markdown syntax for standard files. Use comments that hides OASIS section and digest. This feature should help direct publishing on GitHub.
  • disable_oasis_section (alpha): it allows DisableOASISSection to be specified in the package with a list of expandable filenames given. Any generated file specified in this list doesn't get an OASIS section digest or comment headers and footers and is therefore regenerated each time `oasis setup` is run (and any changes made are lost). This feature is mainly intended for use with StdFiles so that, for example, INSTALL.txt and AUTHORS.txt (which often won't be modified) can have the extra comment lines removed.
  • compiled_setup_ml (alpha): allow to precompile setup.ml to speedup.

This new version closes 4 bugs, mostly related to parsing of _oasis. It also includes a lot of refactoring to improve the overall quality of OASIS code base.

The big project for the next release will be to setup a Windows host for regular build and test on this platform. I plan to use WODI for this setup.

I would like to thanks again the contributor for this release: David Allsopp, Martin Keegan and Jacques-Pascal Deplaix. Their help is greatly appreciated.
