Autodevelop buildout extension

This package provides a buildout extension for automatically developing source eggs in the current project.

You might also want to look at mr.developer which does a similar job but also manages your SCM interactions, which autodevelop explicitly does NOT do.

Finding your develop eggs automatically

You just need to add an extension to your buildout.cfg:

extensions = isotoma.buildout.autodevelop

By default this will check every directory below where you execute buildout for Buildout managed directories like develop-eggs-directory will be excluded. If you want to further restrict the search path, you can till the extension where to search:

extensions = isotoma.buildout.autodevelop
autodevelop =

This will develop any source eggs contained in your src and externals directories.

Testing 'real' eggs automatically

We package all our eggs and deploy from a local PyPI mirror. It's useful to be able to automatically run the egg build and test the buildout with that egg, rather than the checkout. You will flush out your MANIFEST problems if you make use of this.

You need to put the extension into 'localeggs' mode:

extensions = isotoma.buildout.autodevelop

mode = localeggs

Under the hood, the extension will call python sdist for each egg that would have been developed and rewrites ${buildout:find-links} to use that.

Automatic version numbers

You probably won't want this, its a bit of an edge case.

If you are deploying from an SVN tag that contains your source code but you want the deployment to use eggs from your PyPI mirror anyway then autodevelop can automatically update the pins in your buildout to match the version of the code in your tag, by rewriting the [versions] section of your config.

This looks like this:

extensions = isotoma.buildout.autodevelop

 mode = deploy

Optional Parameters

If you don't want to scan the entire checkout, provide a subfolder to check


This software is available from our recipe repository on github.
