From 2fbdd37362a05c380cb2bc2fd8416599e26e9de9 Mon Sep 17 00:00:00 2001 From: Erik Date: Tue, 15 Nov 2016 13:27:39 +0100 Subject: [PATCH 001/108] Initial commit - independent reader / writer object for designspace documents. - imports and exports easy to subclass objects for instance, source and axis data. - roundtrips - intended to be compatible with use in MutatorMath, Superpolatpor and varlib.

So we have: descriptor.filename: the path to the UFO, relative to the documentpath descriptor.path: the resolved, absolute path to the UFO This means we have to be aware of a couple of situations, described in updatePaths() and testPatgNameResolve(). Case 1: both filename and path attributes are None. Action: write the descriptor as is, without filename attr. Case 2: filename attribute points somewhere, but the path attribute is None. So we can't actually verify if the UFO really exists, but we don't have to. Action: write the filename attribute as is. We could calculate a new path though. Case 3: filename attribute is None, path attribute has a path. So there is no legacy value for filename that we need to look out for. Action: we can calculate a new relative path and store that in filename. Case 4: filename and path attributes are not None, but they're in conflict, pointing to different places/ So the absolute path of the UFO and the absolute path of the document produce a different relative path than is stored in filename. One of them must be wrong. When a new filename is set, make sure to set the path attribute to None and vice versa. --- Lib/designSpaceDocument/__init__.py | 166 +++++++++++++++++++++++++--- 1 file changed, 150 insertions(+), 16 deletions(-) diff --git a/Lib/designSpaceDocument/__init__.py b/Lib/designSpaceDocument/__init__.py index b7236de6a..5fa3d4575 100644 --- a/Lib/designSpaceDocument/__init__.py +++ b/Lib/designSpaceDocument/__init__.py @@ -66,7 +66,7 @@ class SourceDescriptor(SimpleDescriptor): def __init__(self): self.filename = None # the original path as found in the document - self.path = None + self.path = None # the absolute path, calculated from filename self.name = None self.location = None self.copyLib = False @@ -159,8 +159,8 @@ class InstanceDescriptor(SimpleDescriptor): 'kerning', 'info'] def __init__(self): - self.filename = None # the original path as found in the document - self.path = None + self.filename = None # the original path as found in the document + self.path = None # the absolute path, calculated from filename self.name = None self.location = None self.familyName = None @@ -570,8 +570,10 @@ class BaseDocReader(object): def readSources(self): for sourceElement in self.root.findall(".sources/source"): filename = sourceElement.attrib.get('filename') - # print("aa", self.path, filename) - sourcePath = os.path.abspath(os.path.join(os.path.dirname(self.path), filename)) + if filename is not None and self.path is not None: + sourcePath = os.path.abspath(os.path.join(os.path.dirname(self.path), filename)) + else: + sourcePath = None sourceName = sourceElement.attrib.get('name') sourceObject = self.sourceDescriptorClass() sourceObject.path = sourcePath # absolute path to the ufo source @@ -802,9 +804,69 @@ class DesignSpaceDocument(object): reader.read() def write(self, path): + self.path = path + self.updatePaths() writer = self.writerClass(path, self) writer.write() + def updatePaths(self): + """ + Right before we save we need to identify and respond to the following situations: + In each descriptor, we have to do the right thing for the filename attribute. + + case 1. + descriptor.filename == None + descriptor.path == None + + -- resolve: + write as is, descriptors will not have a filename attr. + useless, but no reason to interfere. + + + case 2. + descriptor.filename == "../something" + descriptor.path == None + + -- resolve: + write as is.

Data is added to the document +by creating such descriptor objects, filling them with data and then +adding them to the document. This makes it easy to integrate this object +in different contexts. + +The **DesignSpaceDocument** object can be subclassed to work with +different objects, as long as they have the same attributes. + +.. code:: python + + from designSpaceDocument import DesignSpaceDocument + doc = DesignSpaceDocument() + doc.read("some/path/to/my.designspace") + doc.axes + doc.sources + doc.instances + +Validation +========== + +Some validation is done when reading. + +Axes +~~~~ + +- If the ``axes`` element is available in the document then all + locations will check their dimensions against the defined axes.

If you save the document the axes will be + there. + +Default font +~~~~~~~~~~~~ + +- The source with the ``copyInfo`` flag indicates this is the default + font. +- In mutatorMath the default font is selected automatically. A warning + is printed if the mutatorMath default selection differs from the one + set by ``copyInfo``. But the ``copyInfo`` source will be used. +- If no source has a ``copyInfo`` flag, mutatorMath will be used to + select one. This source gets its ``copyInfo`` flag set. If you save + the document this flag will be set. +- Use ``doc.checkDefault()`` to set the default font. + +Localisation +============ + +Some of the descriptors support localised names. The names are stored in +dictionaries using the language code as key. That means that there are +now two places to store names: the old attribute and the new localised +dictionary, ``obj.stylename`` and ``obj.localisedStyleName['en']``. + +Rules +===== + +**The ``rule`` element is experimental.** Some ideas behind how rules +could work in designspaces come from Superpolator. Such rules can maybe +be used to describe some of the conditional GSUB functionality of +OpenType 1.8. The definition of a rule is not that complicated. A rule +has a name, and it has a number of conditions. The rule also contains a +list of glyphname pairs: the glyphs that need to be substituted. + +Variable font instances +~~~~~~~~~~~~~~~~~~~~~~~ + +- In an variable font the substitution happens at run time: there are + no changes in the font, only in the sequence of glyphnames that is + rendered. +- The infrastructure to get this rule data in a variable font needs to + be built. + +UFO instances +~~~~~~~~~~~~~ + +- When making instances as UFOs however, we need to swap the glyphs so + that the original shape is still available. For instance, if a rule + swaps ``a`` for ``a.alt``, but a glyph that references ``a`` in a + component would then show the new ``a.alt``. +- But that can lead to unexpected results. So, if there are no rules + for ``adieresis`` (assuming it references ``a``) then that glyph + **should not change appearance**. That means that when the rule swaps + ``a`` and ``a.alt`` it also swaps all components that reference these + glyphs so they keep their appearance. +- The swap function also needs to take care of swapping the names in + kerning data. + +SourceDescriptor object +----------------------- + +Attributes +~~~~~~~~~~ + +- ``filename``: string.

Such rules can maybe be used to describe some of the conditional GSUB functionality of OpenType 1.8. The definition of a rule is not that complicated. A rule has a name, and it has a number of conditions. The rule also contains a list of glyphname pairs: the glyphs that need to be substituted. - -### Variable font instances -* In an variable font the substitution happens at run time: there are no changes in the font, only in the sequence of glyphnames that is rendered. -* The infrastructure to get this rule data in a variable font needs to be built. - -### UFO instances -* When making instances as UFOs however, we need to swap the glyphs so that the original shape is still available. For instance, if a rule swaps `a` for `a.alt`, but a glyph that references `a` in a component would then show the new `a.alt`. -* But that can lead to unexpected results. So, if there are no rules for `adieresis` (assuming it references `a`) then that glyph **should not change appearance**. That means that when the rule swaps `a` and `a.alt` it also swaps all components that reference these glyphs so they keep their appearance. -* The swap function also needs to take care of swapping the names in kerning data. - -## SourceDescriptor object -### Attributes -* `filename`: string.
