Continuous Integration¶
Since a COGS model is just plain text, many people can collaborate on the same model and synchronize their work using version control software like subversion or git. Outputs can automatically be built whenever the model changes using a continuous integration system. This allows for a transparent development process and fast iterations.
Scenario¶
Whenever a change is made to the model, the model should be validated and all outputs should automatically be generated and uploaded to a staging site where they can be reviewed.
GitLab and AppVeyor Example¶
AppVeyor is a service that provides free continuous integration for open source projects. For an example of how AppVeyor can be configured to perform continuous integration for a COGS model, see the following files from the Structured Data Transform Language (SDTL) model.
AppVeyor Configuration and Initialization¶
The following two files provide the job configuration and dependency installation.
Build Script¶
The following batch file executes all publishers and builds the Sphinx documentation for the model.
Deployment to Staging¶
The following PowerShell script deploys the generated documentation and artifacts to GitLab pages, where it is immediately available on the Web.
