Workflow
To make changes to esy and test them locally:
% git clone git://github.com/esy/esy.git
% cd esy
% esy
% yarn
% node scripts/bootstrap.js
On Linux/macOS (soon on Windows too) you can run:
% make install-githooks
which will install git hooks which will do pre commit validation.
To test the esy executable in development you can use bin/esy.
Updating bin/esyInstallRelease.js
bin/esyInstallRelease.js is developed separately within the esy-install-npm-release/ directory.
Run:
% make bin/esyInstallRelease.js
to update the bin/esyInstallRelease.js file with the latest changed, don't
forget to commit it.
Running Tests
Run:
% 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.0.2.x— maintainance branch for 0.2.x releases.0.3.x— maintainance branch for 0.3.x releases.
Workflow for esy.sh
To make changes to esy.sh:
- Bootstrap site's dev environment:
% make site-bootstrap
- Run site locally:
% make site-start
- 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 for each supported platform (Windows,
macOS and Linux). We employ CI servers (thanks Azure) to build platform specific
releases.
The release workflow is the following:
-
Ensure you are on
masterbranch and assuming you want to release the
version currently defined inpackage.json(see step 6.), run% make release-tag % git push && git push --tags -
Wait till CI finishes its task and release
@esy-nightly/esypackage.You can test it manually.
-
Run
% make release-preparewhich downloads the nightly corresponding to the current commit working
directory is at and "promotes" it to a release. It will create
_release/packagedirectory. -
Ensure release inside
_release/packagedirectory is ok.You can
cd _release/package && npm pack && npm install -g ./esy-*.tgzto test how
release installs and feels. -
Run
% make release-publishto upload the release on npm.
Use
% make NPM_RELEASE_TAG=next release-publishto publish the release under
nexttag (so users won't get it automatically but
only explicitly requested). -
Bump version in
package.jsonto the next patch version.We expect the next version to be mostly a patch version. In case you
want to release new minor or major version you need to bump it before the
release.
