PTP/policy/developer guidelines

PTP adheres to the Eclipse Foundation development conventions and guidelines. Please make sure you read through these before committing code (if you're a committer) or submitting code contributions (if not).

The following practices should also be observed:

Java Errors/Warnings

Developers should override default compiler error/warning and use project specific errors/warnings. These errors should be enabled:

Method with a constructor name - Error Assignment has no effect - Error Possible accidental boolean assignment - Error finally does not complete normally - Error Using a char array in string concatenation - Error Null pointer access - Error Potential null pointer access - Warning Unused Import - Error

All commiters and contributors submitting patches should enable API tooling by setting target baseline platform. Do not commit code with API errors.

Patches with errors listed above including API errors will not be accepted without corrections.

Additional requirements for Java source

  • Use interfaces as much as possible
  • All interfaces and methods must include a Javadoc comment
  • Interface implementations must include a non-Javadoc comment (using Generate Element Comment)
  • All classes, methods and fields should have an access modifier (public, protected, private)
  • Use the following class, method and field modifier order:
    1. Access modifier
    2. abstract
    3. static
    4. final
    5. transient
    6. volatile
  • All source should be formatted using the "Eclipse" built-in code formatter
  • All members should be sorted

Additional requirements for C source

  • All functions must be commented
  • Only include header files that are explicitly used
  • Always initialize variables before use (including static)
  • Always test explicitly for NULL
  • Always use NULL for pointers, not 0
  • Always test for an explicit value from strcmp

C source formatting guidelines:

  • Function body '{' and '}' on their own line
  • Function type on its own line (including static qualifier)
  • Function arguments separated by one space
  • Functions local to a file should be declared static
  • One variable declaration per line
  • Variable declarations should be followed by a blank line
  • No spaces before or after '(' and ')' in functions
  • Opening brace on same line as last ')' in an if statement expression
  • Space separating 'if' and '('
  • No spaces after '(' or before ')' in if statements
  • No braces around return values
  • Opening brace on same line as 'else'
  • 'else' on same line as '}'
  • Only use '/*' and '*/' for comments
  • Put '/*' and '*/' on their own line for multiline comments
  • Start each line of a multiline comment with an '*' aligned with the '*' in the '/*'

Naming conventions for global objects:

  • Capitalize the first letter of each word (e.g.MIBreakpointGetBreakInsertInfo)
  • Do not use '_' or '-'
  • Use descriptive names

Naming conventions for local/utility objects:

  • All lowercase
  • Separate words with '_'
  • Do not use '-'
