0.20.0 to 0.21.0:
* The code from the @Kernel.Base.UserState@ module has been
moved to the module @Kernel.Drawing.Basis@.
* Moved @Image@ and @Query@ from @Objects.Basis@ to new module
@Objects.Image@. Moved @Chain@, @CtxPicture@ and
@TraceDrawing@ into the new @Drawing@ folder.
* Added @Wumpus.Basic.Kernel.Drawing.LocDrawing@ module.
* Rationalized the combinators exported by the drawing objects
@Image@, @LocImage@, @LocThetaImage@ and @Connector@.
0.18.0 to 0.20.0 (no release numbered v0.19.0):
* Added text advance-vector calculations to @QueryDC@ -
previously they were in Wumpus-Drawing.
* Changed argument order of @run@ functions to follow the usual
style - monadic action first and then dependent parameters
(initial state, reader environment etc.).
* Changed representation of Chains to a monadic type with an
explicit operation for next position.
* Removed @PrimW@ type - pairs are now used instead.
* Removed transformer version of @TraceDrawing@. All operations
in TraceDrawing are now specialized to work only on the
@TraceDrawing@ type. Added @UserState@ to TraceDrawing and
other drawing monads to compensate for the loss of
expressiveness.
* Changed the internals of @AdvObject@ and @PosObject@ so they
are more idiomatic - both are now essentially reader-writer
monads. Added PosObject functions for text primitives (moved
from Wumpus-Drawing).
* Changed the @obliterate@ method of the @Decorate@ class.
* Removed the Semigroup (OPlus) and Bifunctor classes. They are
no longer so pertinent now that Image, LocImage etc. are
newtypes rather than /ContextFuns/.
* Changed internals of LocImage, LocThetaImage and Connector
types so the internal points always have Double (PostScript
point) as the unit. This fixes a bug where otherwise changing
the font size for drawings with Em or En units would break the
layout.
* Added @ORIGIN@ to the @RectAddress@ enumeration. I had
overlooked that @BLC /= ORIGIN@.
* Added underline-position and underline-thickness to the font
metrics read by the font loader.
0.17.0 to 0.18.0:
* Major change - removed @ContextFun@ from @Kernel.Base@. Now
the drawing objects (Image, LocImage, Connector...) are
newtype wrapped Reader-Writer monads rather than aliases to
one of the arity family of ContextFuns. Being newtypes gives
a lot better opportunities for overloading.
* Changed Displacement API - it is smaller, and the function
naming is more uniform.
* Changed @DrawingPimitives@ to use @DrawStyle@.
* Moved vertices generating functions from @Geometry.Path@ to
@Geometry.Vertices@.
0.16.0 to 0.17.0:
* Changed representation of ContextFuns - context funs are no
longer an arity family of newtypes. The new representation
is simpler, but some of the opportunities for overloading
have been lost.
* Substantial round of renaming for the @DrawingContext@ types
an query and update functions.
* Re-worked the font metrics and font loader modules. The new
names should be more systematic. Removed the need for the
GhostScript font modules to match PostScript names to
GhostScript font files.
* Superceded the PointSupplyM class by adding snapping grid
scaling to the DrawingContext.
* Removed @ScalingContext@ module.
* Made text colour a distinct property in the DrawingContext.
Text is now drawn with the text colour rather than the stroke
colour.
* Added FontLoadLog to the DrawingContext - this allows access
to the errors recorded during font loading.
0.15.0 to 0.16.0:
* Moved the Geometry modules from Wumpus-Drawing into
Wumpus-Basic.
* Re-worked the @CtxPicture@ API, although the current naming
scheme is not satisfactory.
* Added extra Anchor classes.
* Added @PosImage@ object - this is a rectangle-framed object
that can be drawn from any of its corners or its center.
* Added @CF3@, an arity three /ContextFunction/.
* Added @Displacement@ module. This defines the @PointDisplace@
type and provides a library of @PointDisplace@ functions.
Note - some of the new functions have taken names previously
used for anchor projection functions (@northwards@,
@southwards@, etc.), anchor projections are now build with the
function @projectAnchor@.
* Added the property @descender@ to the font metrics.
* Split drawing primitives from type in @Objects.Graphic@,
drawing primitives are now in the module
@Objects.DrawingPrimitives@.
0.14.0 to 0.15.0:
* Split previous @Wumpus-Basic@ package into two packages:
@Wumpus-Basic@ and @Wumpus-Drawing@. This is a pratical move
to separate the developed (although not yet polished) @Kernel@
and @FontLoader@ code from the prototypical @Drawing@ code.
* Renamed the @Drawing@ object to @CtxPicture@. Although
@CtxPicture@ is a less pleasant name, it should be less
confusing. A @CtxPicture@ is the essentially the @Picture@
type from Wumpus-Core with an implicit context -
@ContextPicture@ is simply too long and @CtxPicture@ is
almost jibberish but the previous unrelated name @Drawing@
was not helpful.
* @Kernel.Base.ScalingContext@ has been simplified.
ScalingContexts are no longer manipulated via a custom Reader
monad or transformer as the type signatures were too unwieldy.
* Added @TextMargin@ to the @DrawingContext@ - Wumpus-Drawing
can now calculate more appealing bounding boxes for text.
0.13.0 to 0.14.0:
* Re-organised module hierarchy, Wumpus-Basic is now divided
into two layers - Basic (Font loader, utils, kernel drawing)
and Drawing - /constructed/ graphic objects like arrows, dots,
etc.
* Re-designed the /ContextFunction/ function types. Context
functions with different numbers of /static arguments/ are
now separate newtypes. This has allowed a major cull of the
combinators operating on context functions (@prepro@,
@postpro@, @situ@, etc.) and now only a handful of special
combinators are needed. As the newtypes are instances of
Monad and Applicative the usual Applicative and Monad
combinators are now more readily useful.
* Work on the font loader code to improve its robustness, and
improved error signalling on load failure. Loading glyph
metrics now returns both the metrics (possibly fallback
metrics if parsing failed) and a log.
0.12.0 to 0.13.0:
* Major changes to @Basic.Graphic@ modules. @DrawingR@ is
renamed @Drawing@ and is substantially re-worked. Graphic
/functional/ types are now encapulated in the Drawing
constructor @Drawing (ctx -> pt -> prim)@ rather than
partially outside it @pt -> Drawing (ctx -> prim)@.
@Drawing@ monad renamed @TraceDrawing@ and @DrawingT@
transformer renamed @TraceDrawingT@.
* Rudimentary font loading added, only AFM files are supported.
* @Basic.Shapes.Coordinate@ re-worked. The Coordinate type is
now more like the Shapes types (excepting the intentional
difference in drawing style).
* @Basic.Shapes.Plaintext@ removed.
* @Basic.Text.LRText@ completely redesigned.
0.11.0 to 0.12.0:
* Changes Base types in @Basic.Graphic@. The @Graphic@ and
@Image@ types now produce (wrapped) @Primitives@, rather than
Hughes lists of @Primitives@. This means they can now be
transformed with the affine transformations. Removed the
function @ati@, it is replaced by @at@.
* Added @Basic.Utils.Combinators@.
* Arrowheads and Connectors reworked - Arrowheads are now a
functional type, Connectors use new Image combining
operations from @Basic.Graphic.Base@.
* Path connectors re-worked and renamed.
* Dot hierarchy changed - @Basic.Dots@ becomes
@Basic.Dots.AnchorDots@; @Basic.Dots.Primitive@ becomes
@Basic.Dots.Marks@.
* @Basic.Shapes@ - internals reworked.
0.10.0 to 0.11.0:
* Reworked arrowheads and connectors - connectors are now
configurable: there are functions to make connectors with
a left arrowhead, right arrowhead, none or both.
* Reworked shapes - internally shapes now create a @Path@ rather
than a @Graphic@ this means the path can be manipulated (e.g.
round cornered rectangles, diamonds... can be constructed).
@Coordinate@ is no longer a @Shape@ - it is now similar object
but of a different type. Likewise, @FreeLabel@ has been
replaced by @Plaintext@ which is not a @Shape@, but has some
similar properties.
* @Basic.Paths.Base@ - @Path@ type changed, @PathEmpty@
constructor removed so empty paths cannot be created. This
allows a better API for taking points on a path. It also
means @Path@ is no longer an instance of Monoid. Type changes
to various functions (e.g. @tipR@, @tipL@) reflecting that as
paths cannot now be empty, functions on them can generally be
total. @toPrimPathU@ removed as converting to a PrimPath as
now always /safe/. @tracePoints@ renamed @traceLinePoints@,
@tracePointsCurve@ renamed @traceCurvePoints@, @midpoint@
renamed @midway@.
* @Basic.Graphic@ - the types @ConnDrawingR@, @ConnGraphic@ etc.
have had their names expanded to @ConnectorDrawingR@,
@ConnectorGraphic@...
* @Basic.SafeFont@ - font names changed to use underscore
separators rather than camelCase. Wumpus generally uses
underscored names for /constants/.
* Removed @conn@ from @Basic.Graphic.Drawing@. Connectors should
be used instead.
* The class @DrawingCtxM@ now has @Applicative@ as a superclass.
* @lineSpacing@ renamed @baselineSpacing@.
0.9.0 to 0.10.0:
* @Basic.Graphic.BaseClasses@ and @Basic.Graphic.BaseTypes@
merged into same module so they can depend on each other
without orphans instances.
* @DrawingF@ renamed to @DrawingR@, the related type synonyms
have also been changed, e.g. @LocDrawingF@ is now
@LocDrawingR@.
* Method names in the @DrawingCtxM@ class changed - @askCtx@ is
now @askDC@, @localCtx@ is now @localize@. Removed the
functions @askDF@, @asksDF@, @pureDF@ that worked for
@DrawingF@ (now @DrawingR@), @DrawingR@ now uses the
Applicative\'s @pure@ and the @DrawingCtxM@ class for these
functionalities.
* @Basic.Graphic.DrawingContext@ - renamed @primary_colour@ to
@stroke_colour@ and @secondary_colour@ to @fill_colour@. The
setter functions has been similarly renamed.
* Added the type synonym @DrawingContextF@ to
@Basic.Graphic.DrawingContext@. Changed relevant function
signatures to use it.
* Re-worked the Path modules - base types entirely different,
connectors entirely different, monadic path construction
largely the same.
* Initial work on round cornered paths.
* Removed the type class @TextAnchor@ from @Basic.Anchors@.
This was a left-over from a previous implementation of
Shapes and is not relevant to the current implementation.
* Added @DirectionContext@ to @Basic.Graphic@.
* @localLG@ removed it can be acheived with composition -
@localize upd . loc_graphic_function@. @lgappend@ is also
removed - it can be recreated applicatively.
0.8.0 to 0.9.0:
* Re-worked @Basic.Text.LRSymbol@ changed the type name and the
types of the run functions. Added more symbols and a new demo
@Symbols.hs@.
* @ScalingContext@ added to @Basic.Graphic@. Changed
@monoTextWidth@ to take a character count, the old behaviour
is recreated by the new function @monoTextLength@.
* @Basic.Graphic.Chain@ removed. It is now superseded by
@Basic.Chains@.
* Added new property to @DrawingContext@ for line spacing
scaling factor, and added a new drawing primitive
@textlineMulti@ for multi-line, left justified labels.
* Synthezied attribute /getters/ such as @textDimensions@ moved
from @Basic.Graphic.DrawingContext@ to the new module
@Basic.Graphic.Query@. The type of all the functions has
changed to DrawingF. @lowerxHeight@ is renamed
@monoLowerxHeight@ emphasizing that the metrics pertain to
monospaced Courier font.
* Added Shapes modules.
* TurtleMonad module - the TurtleDrawing type and run functions
have been removed and the internals have been reworked.
Turtle is now run solely as a /local effect/ within the
Drawing monad.
0.7.0 to 0.8.0:
* Re-introduced LRText and LRSymbol - they now work with
Wumpus-Core\'s kerning support.
* Changes to @Graphic.Basic.BaseTypes@ - @DrawingObject@
renamed to @DrawingF@. @HPrim@ wrapped as a newtype to
support a Monoid instance. Removed @appendGraphic@ and @gcat@
as they can be achieved with @mappend@ and @mconcat@.
@appendAt@ renamed to @lgappend@. @PointT@ remaned to
@PointF@.
* Changes to @Graphic.Basic.Drawing@ - @drawAt@, @drawAtImg@,
@drawConn@, @drawConnImg@ all removed. They are replaced
by @draw@ and @drawi@ together with then new @at@ and @conn@
combinators.
* Changes to @Basic.Graphic.PrimGraphic@ - @localDrawingContext@
renamed to @localLG@ and moved to @Basic.Graphic.BaseTypes@.
* Updates to @Basic.SafeFonts@ to work with changes to
@Wumpus.Core@.
0.6.0 to 0.7.0:
* Major rework of Graphic types, the old types (AGraphic,
GraphicF etc.) and the old drawing monads have been removed.
The new types are based on the AGraphic and related types but
their implementation is different. The new types track the
/graphics state/ within the type (the DrawingContext) plus
how to draw themselves. For real drawings, graphics are
collected with a Writer-like monad the @Basic.Graphic.Drawing@
monad which replaces the DrawingCtx and Trace monads. The
Turtle monad remains and has been updated to work with the new
drawing monads.
* LRText and LRSymbol modules temporarily removed as they
contradict the new, optimized kerning functionality in
@Wumpus.Core@.
0.5.0 to 0.6.0:
* Updates to work with wumpus-core-0.30.0.
* The code from @Basic.Graphic@ has been moved in to
@Basic.Graphic.Primitive@ - this module is due a major
overhaul. @Basic.Graphic@ is now an /import/ shim for
@Basic.Graphic.Primitive@.
0.4.0 to 0.5.0:
* Re-worked the PictureLanguage module.
* SVGColours and X11Colours moved into @Wumpus.Basic.Colour@.
Naming scheme for colours changed to use underscore between
words rather than camelCase.
* Updates to work with wumpus-core-0.30.0.
0.3.0 to 0.4.0:
* Reworked the monads. Monads.DrawingMonad replaces
Monads.Trace, Monads.DrawingCtx, Monads.ConsDrawing. The
SnocDrawing monads have been removed as they were a design
mistake.
* Removed MGraphicF type, added AGraphic.
* Initial work on arrow drawing and extended text drawing.
0.2.0 to 0.3.0 :
* Added the anchors, monads, drawingAttrs...
* Added the module @PictureLanguage@ from Wumpus-Core.
It is located with the path prefix @Wumpus.Deprecated@.
At some point it will be replaced...
* Basic.Graphic - rectangles and lines now take the supplied
point to be the center rather than the bottom-left corner.
Name changes - @circle@ changed to @disk@, @text@ changed to
@textline@.
0.1.1 to 0.2.0:
* Added the module @Wumpus.Basic.Graphic@.
* SafeFonts changed to be size neutral. PostScript\'s
@scalefont@ command (which wumpus-core uses in the generated
output) should be able to scale to any integer size.
* New demo @ColourCharts.hs@.
0.1.0 to 0.1.1:
* Added missing LICENSE file to the Cabal file.
* Added this CHANGES file.
