What is this?
Several people are working on the Jmol source code at the same time, probably including you! To keep track of the changes and make sure no-one accidentally erases the work done by the other contributors, Jmol uses the subversion (SVN) version control system. These systems are a bit cryptic for the beginning user, therefore an overview of the main procedure is given on this wiki page. General introductions can also be found on the internet, for example a short one here, and an on-line book on SVN here (of the book, the chapter Basic Work Cycle gives a good quick start.
Accessing a Release
You can browse the latest source code online or anonymously checkout the project contained in the Subversion (SVN) repository.
To checkout the source code use the following command:
svn co https://jmol.svn.sourceforge.net/svnroot/jmol/trunk/Jmol
This will check out to the Jmol subdirectory on your system.
You can update the source code from withing your Jmol sandbox by saying:
svn update
Compiling a Release
Compiling can be done via command line by starting Ant in the top directory, or via an IDE compiler as Eclipse, Netbeans, or JBuilder. The compiled files will be written to the 'build' subdirectory.
Editing a Release
Changes in the Jmol code should follow the Jmol Coding Style.
Hint: Start looking for the source files for the main parts of the program in the 'src/org/jmol' and 'src/org/openscience' subdirectories.
Commiting a bug fix or new feature
Before commiting updated code to the svn server, always do the following:
- Test your code thoroughly, try different systems and 'incorrect' input.
- When the code is working fine, modify the
Jmol.properties file in src/org/jmol/viewer. Simply use the same format as the other modifications.
For example, a Jmol.properties file could start with :
version=11.3.8_dev # --------------------------------------------------------------------
That means that the next release will probably be 11.3.8 and there has
been no modifications yet in Jmol for this new release
After your modification, the 
Jmol.properties file should for example start with:
version=11.3.8_dev # bug fix: "axes scale ..." did not work for the "axes unitcell" option # --------------------------------------------------------------------
These lines will then simply be copy / pasted by the maintainers into the change log accessible on sourceforge with the new version, and the maintainers can quickly edit the Jmol.properties file to prepare for the next version.
Now you are ready to commit, make sure that you are commiting from the top of the Jmol directory tree. The commit message should be short but descriptive.
svn update svn status # -- at this point, if conflicts appeared after svn update, solve the conflicts, repeat 'svn status' -- # svn diff ant spotless dist ant test svn commit -m "Fixed: axes scale ... did not work for the axes unitcell option"
It is a good idea to keep the jmol-users@lists.sourceforge.net mailing list informed of the changes you made.
SVN Conflicts
'svn update' will check for changes commited to the server in the time since your last update. Possible output is:
A Added D Deleted U Updated C Conflict G Merged
The most problematic message of these ones is probably the 'C' conflict message. For general ways to deal with conflicts, you can check this reference
For example:
~> svn update C src/org/jmol/viewer/Jmol.properties U src/org/jmol/modelsetbio/NucleicMonomer.java Updated to revision 8025.
The conflicting files (marked with a C) need to be checked. Note that 'svn update' will give this warning only once, to see if the conflicts have been solved in the mean time, use 'svn status'.
The conflicting file will contain something like:
version=11.3.8_dev # ----------------------------------------------------------------------------- #version=11.3.7 # bug fix: reading of JVXL files for orbitals loses phase information # bug fix: ACD/Labs nonstandard cml "builtin" property reader # bug fix: isosurface interior cavity was not setting meshdata surfaceSet null <<<<<<< .mine # bug fix: "axes scale ..." did not work for the "axes unitcell" option ======= # bug fix: select dna can select rna if chain is mixed hybrid dna+rna >>>>>>> .r8025
In this case, the line describing the big fix marked as 'mine' need to go up to the 11.3.8_dev part. Also remove the arrows and equal signs. Conflicts within the code will require a lot more attention, so it is smart to update regularly and don't wait very long to commit code that you've finished. After correcting the errors, perform an
svn diff
to check if there are any conflicts left that didn't get fixed.
