Research direction

Start with the Constants section of the Moodle Coding Style page at the linked URL, then review its current guidance and examples alongside the referenced PSR-1 guidance. Done means the page documents class constant naming, makes clear that define() is not the preferred form for new code, and explains the guidance for namespaced constants.

Written by the indexing model from the issue text.

Description

documentation enhancement help wanted needs-triage
What is the Moodle feature that needs documenting?

https://moodledev.io/general/development/policies/codingstyle#constants

The Constants section of the Moodle Coding Style currently only describes global constants, and both examples use define(). It says nothing about class constants, even though they are the preferred form in modern Moodle code and are explicitly covered by PSR-1 (and therefore by PSR-12 and PER-3.0, which we defer to where MCS is silent).

This leaves three gaps:

  • Developers have no documented guidance on class constant naming, and have to infer it from PSR-1.
  • The page implies define() is the normal way to declare a constant in new code.
  • Namespaced constants are not mentioned at all, despite being permitted by PHP and appearing in PSR examples. They don't support autoloading, and the PSR examples using PascalCase are a common source of confusion (see MDLSITE-7040).
Is this documentation specific to a Moodle version?

None
