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.

Workflow for esy.sh

To make changes to esy.sh:

  1. Bootstrap site's dev environment:
% make site-bootstrap
  1. Run site locally:
% make site-start
  1. When you are happy with the changes:
% make site-publish

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.
