ArgoUML : ArgoUML is running on any Java platforms and is available in ten languages (American English, British English, French, German, Italian, Portuguese, Spanish, Russian, Norwegian Bokmål and Chinese).Herewith is an arbitrary list that focuses on free open source interoperable applications mentioning their featured languages.

This page assumes you have a reasonable exposure to Python as well as you have some familiarity with LibreOffice application suite. A discovery of Python within LibreOffice is available from Python Programmer's Guide.Ĭandidates to LibreOffice project can relate to this Wiki to get involved. Beginners to experienced Python coders may benefit from this page's development guidelines. Performance-critical objects (such as numbers).This page is intended for Python macros developers wishing to design or collaborate to LibreOffice applications. To participate in the weak reference mechanism without incurring the overhead on One of the goals of Python's weak reference implementation is to allow any type Occurs, tp_iternext should always set an exceptionĪnd return NULL. The exception can yield slightly better performance. StopIteration in addition to returning NULL avoiding May return NULL without setting an exception, or it may set If the iteration has reached the end, tp_iternext Return a new reference to the next object in the iteration, if there is one. Tp_iter handler should return a new reference Iteration, such as file objects) can implement tp_iterīy returning a new reference to themselves - and should also thereforeĪny iterator object should implement both tp_iter Objects which can only be iterated over once (usually due to side effects of Independent iterators, a new iterator should be created and returned by Here the same guidelinesįor collections (such as lists and tuples) which can support multiple Handler, which must return an iterator object.
