Sumo Logic's Scala-based interactive shell framework

These are the components we provide:

• shellbase-core_2.13 contains everything you need to make a basic, working shell
• shellbase-slack_2.13 contains the necessary pieces to post your commands to Slack.

• help / ? - Displays a summary of available commands.
• clear - Clears the text on the screen
• exit / quit - Exits the current shell
• sleep / zzz - Sleeps for the specified duration. Can use compact time: 5m means 5 minutes
• echo - Writes output to the screen (STDOUT)
• tee - Lets you fork stdout to a file
• time - Time how long a command took
• run_script / script - Execute the specified script. Will attempt to be smart about locating

We've put together a very simple example shell that can generate random numbers.

To build project in default Scala version:

./gradlew build

To build project in any supported Scala version:

./gradlew build -PscalaVersion=2.13.10

For testing, change your consumer pom.xml or gradle.properties to depend on the SNAPSHOT version generated. Make sure, your consumer can resolve artifacts from a local repository.

This project supports multiple versions of Scala. Supported versions are listed in gradle.properties.

• supportedScalaVersions - list of supported versions (Gradle prevents building with versions from outside this list)
• defaultScalaVersion - default version of Scala used for building - can be overridden with -PscalaVersion

1. Make sure you have all credentials.
   1. Can login as sumoapi https://oss.sonatype.org/index.html
   2. Can import and verify the signing key:

      gpg --import ~/Desktop/api.private.key
      gpg-agent --daemon
      touch a
      gpg --use-agent --sign a
      gpg -k
      

   3. Have nexus and signing credentials in ~/.gradle/gradle.properties

      nexus_username=sumoapi
      nexus_password=${sumoapi_password_for_sonatype_nexus}
      signing.gnupg.executable=gpg
      signing.gnupg.keyName=${id_of_imported_sumoapi_key}
      signing.gnupg.passphrase=${password_for_imported_sumoapi_key}
      

2. Remove -SNAPSHOT suffix from version in build.gradle
3. Make a release branch with Scala version and project version, ex. shellbase-3.0.1:

   export RELEASE_VERSION=shellbase-3.0.1
   git checkout -b ${RELEASE_VERSION}
   git add build.gradle
   git commit -m "[release] ${RELEASE_VERSION}"
   

4. Perform a release in selected Scala versions:

   ./gradlew shellbase-example:publish -PscalaVersion=2.12.17
   ./gradlew shellbase-slack:publish -PscalaVersion=2.12.17
   ./gradlew shellbase-core:publish -PscalaVersion=2.12.17
   ./gradlew shellbase-example:publish -PscalaVersion=2.13.10
   ./gradlew shellbase-slack:publish -PscalaVersion=2.13.10
   ./gradlew shellbase-core:publish -PscalaVersion=2.13.10
   
   

5. Go to https://oss.sonatype.org/index.html#stagingRepositories, search for com.sumologic, close and release your repo. NOTE: If you had to login, reload the URL. It doesn't take you to the right page post-login
6. Update the README.md and CHANGELOG.md with the new version and set upcoming snapshot version in build.gradle, ex. 3.0.2-SNAPSHOT
7. Commit the change and push as a PR:

   git add build.gradle README.md CHANGELOG.md
   git commit -m "[release] Updating version after release ${RELEASE_VERSION}"
   git push
