Re: [cinjug-users] Constants imply DP (was: Question on last Monday's meeting)

Automate. I didn't test it but you get the idea. Code generation rocks.

MyConstants.properties
   something=somethingelse

Generate Code.sh
   echo "class MyConstants {" > MyConstants.java
   cat MyContants.properties | \
       sed -e "s/([^)])=([^)])/String \1 = \"\2\";" >> MyConstants.java
   echo "}" >> MyConstants.java

   cat MyContants.properties |
       sed -e "s/([^)])=([^)])/    var \1 = \"\2\";" > MyConstants.js

A more elegant way would be to use ant and use its copy file with filter 
variables to generate the language specific files from build variables.
