Workflow

To make changes to esy and test them locally:

% git clone git://github.com/esy/esy.git
% cd esy
% make bootstrap

Run:

% make

to see the description of development workflow.

Running Tests

% make test

Branches

There are two branches:

• master — the active development, we cut new versions out of there regularly.
• 0.0.x — maintainance branch for 0.0.x releases.

Issues

Issues are tracked at esy/esy.

Publishing Releases

esy is released on npm.

Because esy is written in OCaml/Reason and compiled into a native executable we need to acquire a set of prebuilt binaries. We employ CI servers (thanks Travis CI) to build platform specific releases.

The release workflow is the following:

1. Ensure you arre on master branch and run

   % make bump-patch-verson
   % git push && git push --tags
   

   (this bumps patch version, use bump-minor-version or bump-major-version correspondingly to bump either minor or major version of esy)

2. Wait till CI finishes its task and uploads releases on GitHub, check https://github.com/esy/esy/releases for them.

3. Run

   % make release
   

   Which downloads platform specific releases (which CI uploaded GitHub) and produces an npm releases with needed metadata inside _release directory.

4. Ensure release inside _release directory is ok.

   You can cd _release && npm pack && npm install -g ./esy-*.tgz to test how release installs and feels.

5. Run cd _release && npm publish to publish release on npm.

   Release tag next is used to publish preview releases.
