Development Guidelines

How your code should look like

• make sure the code is Java 1.5 compatible: no missing @Override or @Deprecated
• make sure there is no trailing white space
• don't use multiple consecutive empty lines

Configuring Eclipse

Internationalization

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

  import import static org.openstreetmap.josm.tools.I18n.tr;
  
  threw new Exception(tr("error message always in tr()"));
  
  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.
