PyX

TODO:
  - style module:
    - default patterns
    - make dash length available
  - text module:
    - SlantFont & Co support
    - keep an eye on PEP 324 (popen 5): it could make the texrunner much easier
    - messageparser for replaced fontsizes: Warning
    - messageparser for size differences at the end: Warning not Exception
    - messageparser for overfull/underfull vbox/hbox: Warning not Exception
    - newline removal when not disturbing texmessages only
  - graph.graph module
    - common bboxes for different graphs
    - 3d graphs, circular graphs
    - axis painter labelattrs=None + automatic axis partitioning leads to no valid partitioning
    - when all titles are None, a graph key currently raises an exception
    - translatecanvas should be the default in graph.style.symbol
  - graph.style and graph.data modules
    - exceptions in drawsymbol & friends...
    - fix docu (or code) of gridattrs functionality of axis painters
      (how can one, e.g. draw a grid at the ticks and not at the subticks)
  - graph.data module:
    - use csv module (new in 2.3)
    - Check for "inf" and "nan" in datafiles.
      (When plotted, the graph does not complain, but the postscript will be broken)
  - graph.style module:
    - add styles using curves instead of lines
    - add "steps" style for histogram-like plots
  - canvas module:
    - contructor should only take a texrunner keyword argument
    - set method???
    - SVG support
  - style and color module:
    - support modification of existing styles via __call__
  - bbox module:
    - height -> getheight, ...
  - mathtree:
    - might be moved into the graph
    - perform calc by means of Python itself (see eval code in graph.data, but
      we should use compiled code instead of eval)
  - dvifile module:
    - support single-character mode
  - color module:
    - what should we do for palette when only one entry
  - connector module:
    - is the early conversion with unit.topt unit-modification-save?
  - deformer module:
    - better names for the helper functions ?
    - why does smoothed through away short normpathitems instead of simply ignoring them?
      Where is the difference? [MS]
  - open discussion:
    - clearly distingish between readers and writers. dvifile, epsfile, etc. might
      be renamed to dvireader, epsreader ...
  - canvas module:
    - stroking of patterns does not work in PDF
    - patterns call the outputPS method in registerPS and have no writer at that 
      time -> rewrite this code

  Documentation:
    - path module:
      - describe + vs <<
      - more details in path constructor: allowed pathels, first pathel...
      - set method
    - deco module:

    - box module:
      - linealign and circlealign
    - unit module:
      update length constructor description (strings are no longer supported, etc.)
    - graph module:
      styles: document what data name the styles accept (require). Try also to be more
      userfriendly and not to describe immediately the internals of the implementation:
      (see e.g. class.style.symbol)

      of the bbox
    - enlarge and enlarged do no longer interprete unqualified lengths as

  - unit module:
    - unit.cm, unit.t_cm, etc. are no longer sub classes but instances

    - create siteconfig on install to store positions of the shared data
      and the global pyxrc
  - graph modules:

      - modularization of the graph styles by separating data handling and drawing tasks

      from a path.
    - normsubpath can now deal with short (i.e. shorter than epsilon) segments correctly
    - the intersect and split methods of normpath and normsubpath have been completely rewritten and
      now take the accuracy epsilon correctly into account. Note that for a closed subpath the
      split function now returns the segment containing the closing point as first element

      small pending issues, but the basic restructuring is done with this release):
      - graph splitted into several modules in pyx/graph and pyx/graph/axis
      - painters are using the new attribute scheme including changeable
        attributes
      - graph styles rewrite
      - graph data rewrite
    - axis zeropath feature has been removed

      normsubpaths which themselves consist of normlines and normcurves This is
      much more convenient for any routines working with normpaths.
    - reversing of closed sub paths does not change the first point of the sub
      path
    - renamed: arclength -> arclen
    - renamed: lentopar -> arclentoparam
    - renamed: glue -> joined
    - normpath now supports join, the in-place version of joined
    - path and normpath method raise exception instead of returning None

    - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
  - bbox module:
     - added inplace add (__iadd__), enlarge and transform methods
     - callers use inplace add where possible now (yielding a considerable
       speedup)

  - unit module:
    - new classes for visual and width lengths, aliases for user length (u_pt = pt)
    - all length classes have now by default a quantifier 1 (instead of 0), such that,
      for instance, 5*unit.t_cm() == unit.t_cm(5)
    - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
    - convert_to is now an internal function, which moreover does not longer accept tuples or lists
  - bbox module:
    - new class _bbox (the former bbox) which accepts points in the constructor. This is used
      for internal purposes.
    - the bbox constructor now accepts user lengths in the constructor.
    - new methods height, width, top, bottom, left, right
    - ll & ur ???, what about ul and lr -> ugly!
    - enlarge (was enhance) now allows selective enlargement to the left, bottom, right and top
    - output HiResBoundingBox
    - never reduce bbox upon output
  - epsfile module:
    - new constructor signature, more in line with rest of PyX:
      epsfile(x, y, filename, **additional_args)
  - data module:
    - removed additional column support in addcolumn; removed _addcolumn
    - line reduction for datafile like the every parameter in gnuplot
  - canvas module:
    - new way of PS prolog generation that writes only necessary parts
    - added support for patterns
    - canvas.insert() now supports arguments
    - bbox of canvas can be specified in writetofile command explicitely
    - writetofile does not return self anymore
    - arrow template now uses intersection with circle to get size right
      (as per a suggestion by Michael Schindler)
  - mathtree module:
    - added abs function
    - changed the handling of extern functions and all variables
  - color module:
    - gradient renamed to palette
  - numerous bugfixes:
    - problem with sizefile on windows (tex module)
    - allow for strings in graphxy's width and height; allow for width only (graph module)
    - disable rating for labelattrs equals None (graph module)
    - defaultstyle selection, when a list of data is provided to the plot function (graph module)
    - traverse when adding functions as arguments of operators (mathtree module)
    - allow for extern functions in addcolumn (data module)
    - just one common place for the version number
    - fix incorrect exception name MathError (path module)
    - prevent double return of intersections for closed sub paths
    - ...

0.2 (2003/01/17):
  - unit module:
    - allow division of length by numbers
  - trafo module:
    - new transformation: slant
    - renamed all trafo methods to use the participle (i.e translate->translated)
    - the name of all trafo subclasses are verbs (i.e. translation->translate)
  - graph module:
    - mark class renamed to symbol
    - (text-)box distance measurement
    - moved axis partitioning to axis and axis painter
    - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
    - splitaxis
    - baraxis, baraxispainter, and bar style
  - data module:
    - previously named datafile module
    - class "_datafile" renamed to class "data"
    - class sectionfile added
    - testsuite
  - mathtree module:
    - extern variables and functions (support in graph.function, graph.paramfunction and data.data)
    - testsuite
  - text module:
    - deferred to Version 0.3
    - running TeX "on the fly" is basically implemented
  - numerous bugfixes:
    - transformation bug (#624068, trafo module)
    - canvas transformations (canvas module???)
    - textbox alignment (graph module)
    - return linewidth upon calculation with linewidths (unit module)
    - allow column number variables with several digits
    - ...
