Note, this has been superceded by the version in the most recent Ptolemy II release.


Collaborative software projects benefit when participants read code created by other participants. The objective of a coding style is to reduce the fatigue induced by unimportant formatting differences and differences in naming conventions. Although individual programmers will undoubtedly have preferences and habits that differ from the recommendations here, the benefits that flow from following these recommendations far outweigh the inconveniences. Published papers in journals are subject to similar stylistic and layout constraints, so such constraints are not new to the academic community.

Software written by the Ptolemy Project participants follows a variant of this style guide. Although many of these conventions are arbitrary, the resulting consistency makes reading the code much easier, once you get used to the conventions. We recommend that if you extend Ptolemy II in any way, that you follow these conventions. To be included in future versions of Ptolemy II, the code must follow the conventions.
