How do I create a directory for my codes?

When you start developing MercuryDPM applications ("Drivers"), you need a directory in which to store them. All MercuryDPM developers can should create a directory to store their aplications, and use svn for version control. Here is how you do it:

1. Open a terminal, enter the subfolder Drivers/USER in the source directory, and svn-copy the template USER directory into a directory named after you, e.g.

   MercurySource/Drivers/USER$ svn cp Template Marlin

2. Enter your directory. If you have already written a driver code, svn-remove the template driver, copy your driver into your folder and svn-add the driver.

   MercurySource/Drivers/USER$ cd Marlin
   MercurySource/Drivers/USER/Marlin$ cp $DIRECTORY/MyFirstDriver.cpp .
   MercurySource/Drivers/USER/Marlin$ svn add MyFirstDriver.cpp
   MercurySource/Drivers/USER/Marlin$ svn rm TemplateDriver.cpp

   If you are just starting to develop a driver, and svn-rename the template driver to the name you want to give your driver, e.g.

   MercurySource/Drivers/USER$ cd Marlin
   MercurySource/Drivers/USER/Marlin$ svn mv TemplateDriver.cpp MyFirstDriver.cpp

3. return to your build directory and update cmake.

   MercurySource/Drivers/USER/Marlin$ cd ../../../../MercuryBuild
   MercuryBuild$ cmake .
   -- Build files have been written to: /Users/weinhartt/Mercury/Trunk/cmake-build-debug

   Updating cmake made a make command for your driver, you can test this:

   MercuryBuild$ make MyFirstDriver
   [100%] Built target MyFirstDriver

4. then check-in your changes (after testing that all codes compile):

   MercuryBuild$ make fullTest
   MercuryBuild$ cd ../MercurySource
   MercurySource$ svn st
   A  +    Drivers/USER/Marlin
   A  +    Drivers/USER/Marlin/MyFirstDriver.cpp
   D  +    Drivers/USER/Marlin/TemplateDriver.cpp
   MercurySource$ svn ci -m "added a USER directory named Marlin"

   Now you can modify the driver code to your specific application.
