Antlr plugin set up for cps-path-parser (optional)

The cps-path-parser module uses Antlr. IntelliJ has an Antlr-v4 plugin If you want to use it it needs to be configured as follows:

  1. Right-click on cps-path-parser/src/main/antlr4/org/onap/cps/cpspath/parser/antlr4/CpsPath.g4 file in the project file tree.
  2. Select "Configure ANTLR..."
  3. Set "Output directory where all output is generated" to <your git repo>\cps-path-parser\target\generated-sources\antlr4
  4. Set "Package/namespace for the generated code" to: org.onap.cps.cpspath.parser.antlr4
  5. Click [OK] 

CPS Specific Code Style set up

  • InteliJ IDE: As we have noticed some slight formatting issues that are not controlled by the IDE we prefer that CPS contributors use IntelliJ (community edition is perfectly good for Java development)
  • CPS CheckStyle Scheme: CPS as extended the standard ONAP CheckStyle configuration. Once you have downloaded CPS you can find the definition in <your_git_folder>checkstyle/src/main/resources/cps-java-style.xml
  • Groovy: CPS uses Groovy/Spock for unit testing. There is some additional formatting setup to ensure consistent formatting of Groovy files.

Configure CPS code CheckStyle Plugin for IntelliJ

  1. Select, File, Settings, Tools, Checkstyle  
  2. Click on + beside the 'Configuration File' box to add a configuration
  3. Set description to something like 'ONAP Rules'
  4. Click on Browse to select the file <your_git_folder>checkstyle/src/main/resources/cps-java-style.xml
  5. Complete the Wizard (you can set exclusion properties if needed)
  6. Activate the Configuration File you just added by selecting the relevant checkbox
  7. optional: Click [OK] to close the settings popup

Configure CPS code style auto formatting for IntelliJ (using the same CheckStyle rules and automating it for you (smile))

  1. Select, File, Settings, Editor, Code Style
  2. Click on the gear icon at the end of the line for "Scheme:"
  3. Optional: As importing a schema overrides the current scheme you might want to first use the 'Duplicate..' and  'Rename...' options to create an easily identifiable scheme e.g. 'CPS Standard'
  4. Import Scheme→Checkstyle Configuration
  5. Click on Browse to select the file  <your_git_folder>checkstyle/src/main/resources/cps-java-style.xml
  6. optional: Click [OK] to close the settings popup

Configure CPS Java code style auto formatting for IntelliJ

  1. Select, File, Settings, Editor, Code Style, Java
  2. Ensure the same scheme is selected (as suggested in step 3 in the previous instructions: 'CPS Standard')
  3. Click [OK] to close the settings popup

Configure CPS Groovy code style auto formatting for IntelliJ

  1. Select, File, Settings, Editor, Code Style, Groovy
  2. Ensure the same scheme is selected (as suggested in step 3 in the previous instructions: 'CPS Standard') However does does not affect Groovy setting and you manually need to set below too:
    1. Select 'Tabs and Indents' tab
    2. Set 'Tab size' to 4
    3. Set 'Indent' to 4
    4. Set 'Continuation indent' to 4
    5. Set 'Label indent' to (this is the only one that is different from Java and it to indent under the give: when then: labels!)
    6. Select 'Imports' tab
    7. Set 'Class count to use import with '*'' to 999
    8. Set 'Names count to use static import with '*'' to 999
  3. Click [OK] to close the settings popup

Common Style Conventions

FieldUPPER_SNAKE_CASEDATASPACE_ID
LiquibaseTablelower_snake_casefragment
Fieldlower_snake_casedataspace_id

*A caveat to these styling conventions is that we should try to conform to the model which we are developing for. So if we model in yang we should manipulate that data using the kebab-casing convention as that is the convention used in yang models. However there are some endpoints where a convention has been set to use camelCasing when manipulating yang data. In these cases the current convention should be upheld to avoid backward incompatible changes.

Code Analysis

We recommend that most user stories are accompanied with  small wiki page to document/clarify some analysis for that user story.

See Implementation Proposals

Unit Test

CPS is promoting Groovy and Spock for our unit test. All new modified code should include good quality test

see Groovy & Spock you can also contact the PTL Toine Siebelink for more details


DB Schema  Changes (Liquibase Change Sets)

See

User Story Demos

As part of our best practice to finish a user story it should be demonstrated to team and if possible recorded

see CPS User Story Demos

Jenkins Job 

ONAP uses Jenkins based CICD tool chain.  However, contributors are only given read access to the Jenkins servers.  All jobs are created by automatic generation from JJB definitions.
