= Development Guidelines =

== How your code should look like ==

 * make sure the code is Java 1.6 compatible
 * make sure there is no trailing white space
 * don't use multiple consecutive empty lines
 * JOSM uses 4 characters indentation and no tab stops
 * Document your code '''thoroughly'''. Many people will thank you :)

== 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.

 * When using apostrophe, the following rules apply:
   
   For all {{{tr}}} the apostrophe is special. (Like backslash in C)[[BR]]
   It needs to be escaped by another apostrophe:

   {{{new JButton(tr("Don''t press me more than {0} times!", n))}}}
