OpenAtlas is developed with some standards in mind.

Open source

To guaranty that the OpenAtlas application can be shared as open source (GPL 2) make sure that:
  • Only open source software is used and required
  • Non-code files are open data, e.g. a CC BY 4.0 license for images
  • When including 3rd party software or media it is important to:
    • Make sure that the license is compatible
    • Add a license file if available
    • Place them in openatlas/static/vendor

Bugs

Of course we do our best to avoid them in the first place but if bugs get apparent they always have the highest priority.

HTML

  • Standard: HTML 5. Exceptions may be acceptable if invalid but harmless HTML 5 is produced by 3rd party libraries.
  • Indentation: 2 spaces

Type-/JavaScript

  • Indentation: 2 spaces
  • Use semicolons at the end of statements, see Eslint: Semi Always for details.
Version Setup Configuration
Eslint 8.35.0 Through npm in relevant projects .eslintrc Checks for errors, coding standards and code smells in js/ts code

CSS

  • Indentation: 2 spaces

Python

  • Indentation: 4 spaces
  • Listed below are used standards and tests
Version PyCharm Configuration
PEP 8 integrated Style guide for Python code
nose tests 1.3.7 integrated tests/.noserc
tests/.coveragerc
Cover Python code using assertions, some parts (e.g. mail) are excluded via # pragma: no cover.
Can be run manually with: nosetests3 -c tests/.noserc
Mypy 1.01 plugin Mypy mypy.ini Optional static type checker for Python
Pylint 2.16.2 plugin Pylint .pylintrc Checks for errors, coding standards and code smells
SonarQube 5 sonar-project.properties Cumbersome to install (so not mandatory for developers) but interesting code hints. PyCharm plugin exists but doesn't seem to work for Python

Radon can be used to compute various code metrics. Installation: apt install radon. To show e.g. metrics about cyclic complexity: radon cc openatlas

Software packages (Debian)

Although pip offers some advantages (e.g more current packages and usable for different installation environments) we prefer packages from the Debian repository for the OpenAtlas backend.
Main reasons concern security, reliability and stability.
