Structure:

• Introduction
• Naming Conventions
• Comments and Documentation (you can get it from here: https://github.com/AdguardTeam/CodeGuidelines/blob/master/Java.md#comments-and-documentation)
• General Code Quality (short language-specific points about code quality)
• Best Practices (detailed guides, more common than the code quality points)

I think it is worth considering compiling a guideline for Adblock Filter Lists.

In my opinion, there are two main groups of policies:

• Syntactic / formatting specifications
• Application specifications: routines, best practices <-> bad practices

I think such guidelines could be:

• Preferred scriptlet quote marks,
• Formatting of CSS selectors, e.g. whether there should be a space before !important
• Application of general <-> specific principles (e.g. EasyList is a very general list, and AG filters are more specific),
• Contraindication of multiple selectors within a rule: example.com##.ad1, .ad2
• Taking into account the limitations of content blockers, e.g. creating regular exception network rules next to scriptlets
• Comment guides, e.g. put one space after comment marker, link issues before rules
• Rule ordering/grouping, where to place a new rule
• Where to place a new domain if the rule is already exists
• etc.

The description of the filter repo doesn't cover such things:

I would be happy if you could share your opinion. 🙂

I propose to consider Airbnb JavaScript guidelines
https://github.com/airbnb/javascript

They updates guide regularly, I think it will be convenient for us.
