Juno-2 is a drawing editor that features a powerful constraint
|
|
solver, extensibility through an embedded programming and constraint
|
|
definition language, and double-view editing.
|
|
|
|
Constraints allow you to specify locations in your drawing
|
|
declaratively. For example, to draw an equilateral triangle, you
|
|
first draw an arbitrary triangle and then constrain its sides to
|
|
be equal; Juno-2 will adjust the vertices to make the triangle
|
|
equilateral. Moreover, the constraints are maintained whenever part of
|
|
the picture is changed, so constraints make it easier to maintain a
|
|
picture in the face of modifications.
|
|
|
|
Constraints in Juno-2 are declarative, and they can include non-linear
|
|
functions and ordered pairs. Moreover, the Juno-2 constraint solver is
|
|
not limited to acyclic constraint systems. This means that Juno-2's
|
|
constraint solver is significantly more powerful and easier to use
|
|
than other ``one-way'' constraint solvers such as DeltaBlue.
|
|
|
|
This port installs some examples into "${PREFIX}/share/examples/Juno".
|
|
Not all of them work; read the README file there.
