The development flow includes:

Create workspace, clone sources

To create a workpace you can use devfile:

$ dsc workspace:start -f https://raw.githubusercontent.com/redhat-developer/devspaces-chectl/master/devfile.yaml

See more about devfile

After starting the workspace Theia will clone sources of dsc to /projects/dsc directory.

dsc is written in TypeScript. For its development there is a dedicated dev container which has preinstalled software for comfortable development. That allows the developer to build, test and launch dsc inside the container.

You workspace is initialized with a list of commands described in the devfile in commands section. Those command allow you to:

  • build
  • test
  • generate devfile
  • create workspace
  • package binaries
  • format sources

You can run commands in one of three ways.

  1. It an easiest way is to use My Workspace panel at the left. You can launch commands by simple click.

  2. Terminal => Run Task... menu. You can fin and pick a command in the appeared command palette.

  3. Manually by opening a terminal in the dev container and running commands in /projects/dsc directory.

Build

yarn

Open My Workspace panel at the left and launch Build command. It will run yarn command in /projects/dsc directory inside dev container. The command will install all necessary dependencies and compile the project. Upon successfull assembly, a new bin directory will appear in project directory and will have two files: run and run.cmd.

Run tests

yarn test

Tests for dsc are written using jest framework. To run tests, go to My Workspace panel, find and launch Test command. The command will run yarn test inside dev container. Testing summary will be printed to the output.

Run

./bin/run --help

To test ensure dsc is built successfully, launch Run command. It wil run dsc with --help directive.

Generate Devfile

./bin/run devfile:generate \
    --name="dsc-test" \
    --language="typescript" \
    --dockerimage="quay.io/devspaces/theia-dev-rhel8:latest" \
    --git-repo="https://github.com/redhat-developer/devspaces-chectl.git" \
    --command="yarn" > /projects/sample.devfile

We added a command which generates a simple devfile /projects/sample.devfile. Workspace created from this devfile will have dsc project with running TypeScript language server. There will be a dev container for building, running and debugging dsc. It will be possible to easily build dsc by running yarn command from My Workspace.

Create Workspace

We still found a solution how to create a workspace by a command from container.

# upload devfile content to clbin, save link into a file
cat /projects/sample.devfile | curl -F 'clbin=<-' https://clbin.com > /projects/clbin

# run dsc, pass the given URI
uri=$(cat /projects/clbin); ./run workspace:start -f=$uri

To create a workspsace run Create Workspace command from My Workspace. The command will upload content of the generated /projects/sample.devfile devfile to https://clbin.com. And then will use given public URI to the devfile when running dsc.

Package binaries

For packaging binaries, oclif is used. It generates packages for Linux, Windows and MacOS operation systems and puts the result in dist/channels/stable directory. To start packaging just run Package Binaries commands from My Workspace. It will run the following in /projects/dsc directory.

yarn oclif-dev pack

Note: you need to build your dsc before by yarn command, or install all node packages by running npm install in /projects/dsc directory.

Push changes, provide Pull Request

dsc is using several Pull Request checks

  • Conventional Commits convention for the commit messages. There is a required Pull Request check named Semantic Pull Request that is ensuring that all commits messages are correctly setup. In order to merge a Pull Request, it has to be green.

  • Signed Commits. Each commit needs to have the Signed-off part It needs to be added on the commit message:

feat(hello): This is my first commit message

Signed-off-by: John Doe <dsc@redhat.com>

Git even has a -s command line option to append this automatically to your commit message:

$ git commit -s -m 'feat(hello): This is my first commit message'
  • Unit tests with Travis-CI. It will ensure that yarn test command is passing.

All these checks are mandatory in order to have the Pull Request merged.

Make Release

Create 7.0.0 version

$ ./make-release.sh 7.0.0

To run the script with docker env

$ ./run-script-in-docker.sh make-release.sh 7.0.0

Commit the changes of the script and then, push release branch by overriding current remote release branch
