Direct python API to generate a diagram

[Al]

Is there any documentation (or doxygen) for creating sequence diagrams
directly from python code?
When all the relevant information (sequence diagram interactions) are
already available in native form in python, it is simpler to call the
API to build the diagram rather then generate a .diag file and call
seqdiag to generate the image.

Thanks

Hi

Sorry, there are no documents for python codes.

You can use blockdiag API like this::

from blockdiag import parser, builder, drawer

tree = parser.parse_string(source)
diagram = builder.ScreenNodeBuilder.build(tree)
draw = drawer.DiagramDraw('PNG', diagram, filename="foo.png")
draw.draw()
draw.save()

This is another example using blockdiag API
(works at http://interactive.blockdiag.com/ )

Hi,

This problem looks like no setuptools. Are you using it for setup?
blockdiag needs it for pluggable structure (entry_point feature).
