Development Guidelines

How your code should look like

• make sure the code is Java 1.5 compatible
  • no @Override for methods for implemented interfaces
• make sure there is no trailing white space
• don't use multiple consecutive empty lines
• Document your code thoroughly. Many people will thank you :)

Configuring Eclipse

Internationalization

• make sure you use use tr(...) for all localized strings

  import import static org.openstreetmap.josm.tools.I18n.tr;
  
  // use tr(...) for exception messages
  //
  throw new Exception(tr("error message always in tr()"));
  
  // use tr(...) for labels, title, tooltip texts and the like 
  //
  new JLabel(tr("Label always in tr()"));
  
  // etc.
  

• never assemble localized messages with +. Use format placeholders instead.

DONT new JLabel(tr("My Label " + labelId));

DO new JLabel(tr("My Label {0}",labelId));

Only exception: + can be used to break long lines of non-variable texts.
