Code Style

Please follow this code style when contributing to rwkv.cpp.

This list is not complete.

General

Overall, keep code in similar style as it was before.

• Keep lines at 180 characters or shorter.
• Separate logically grouped pieces of code with empty lines.
• Surround if, for, while, do and other similar statements with empty lines.
• Write documentation for public functions indended for outside use.
• Place single-line comments on the line before, not right after the code line.
• Start comments with a capital letter, use correct grammar and punctuation.

C/C++

• Use 4 spaces for indentation.
• Use The One True Brace Style:
  • Place braces on the same line as the statement.
  • Always add braces to if, for, while, do and other similar statements.

Python

• Use 2 spaces for indentation.
• Specify types for functions and parameters.
  • For void functions, specify -> None.
• Specifying types for local variables:
  • required, if they are global
  • required, if they are compound (lists, dicts, optionals, etc.)
  • optional otherwise.
• Use types from typing (List, Dict) instead of built-in (list, dict).
