Release Procedures

Jmol/JSmol Development

• Getting Involved in J(S)mol evolution
• Release Procedures
• Important! Use the Jmol Coding Style
• Developing J(S)mol with Eclipse
• Internationalisation (status)
• ProgrammeerZomer / SummerOfCode
• MultiUser Jmol
• Developer mailing list (mirror)

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 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 already commited. Possible output is:

   A  Added
   D  Deleted
   U  Updated
   C  Conflict
   G  Merged

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 by hand. Note that 'svn update' will give this warning only once, so do the corrections immediately, or you will forget about them!

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.
