A property _ObjectUUID will be added to an object before it is being to
copied, if the property does not exists. Anoter propert _SourceUUID
property will be added to any copied object, with value set to its
source objct's _ObjectUUID.
To compare if two property contains the same content. The default
implementation in Property uses the persistense interface to save both
properties to string and compares the content. This may not work at the
moment if the property saves content in separate file or in binary.
Various properties have cheaper implementation to direct compare their
internal values.
New property status bit 'CopyOnChange' is added for any document object
to publish any property as a 'Configuration' option. When Link is
linked to any object with such property, it will duplicate those
properties and added it Link itself as dynamic properties. If the user
changes any of these dynamic properties, the Link will auto copy the
linked to object and apply the new configuration to it.
The Link has a new property 'LinkCopyOnChange' to allow user to
enable/disable this feature.
Spreadsheet's 'Configuration Table' feature will publish its
configuration property with 'CopyOnChange'.
Currently, once the linked object is copied, it will be independent with
the original object. There is no mechanism to auto sync changes back to
the copy.
No longer add dynamic property for alias, simply rely on
get(Dynamic)PropertyByName() to check for aliases.
Add new API PropertyContainer::getPropertyNamedList() so that
ExpressionCompleter can discover properties with aliases.
Cell binding allows one to bind a range of cells of one sheet to another
range of cells of an arbitary sheet, including any empty cells in the
range.
The binding is implemented with PropertyExpressionEngine and
PropertySheet::setPathValue(), which binds a special path of
PropertySheet, such as
.cells.Bind.A1.D1
to an expression, such as
tuple(.cells, <<A2>>, <<A5>>)
The A1 and D1 in the example above specifies the binding start and end
cell address. And <<A2>> and <<A5>> are the range of cells to bind to.
Note that you can use any expression that evalutes to string for the
binding destination, e.g. <<A%d>> % B1, which uses the value inside B1
to construct the binding destination. The '.cells' in the tuple shown
above is an example to bind cells of the same PropertySheet. It can be
change to to reference to any other spreadsheet, even those outside the
current document, e.g. Document#Spreadsheet001.cells
+ it's an obscure way to clear the error state by instantiating PyException, instead use the clear() method
+ do not handle unknown exceptions because this suppresses all exceptions and thus makes error search more complicated
Rather than trying to use a generic Py::Object and assigning properties
to it, use a Py::Dict object for simple data structures like Url,
Maintainer, and Author.
Update metadata standard to include subdirectory
Constructing a string from a null pointer is undefined behavior: it
turned out to work with gcc and MSVC, but with XCode/clang it results in
a segmentation fault. Theis fix assumes that the expected behavior is to
yield an empty string.
Changes the way PropertyContainer handles existing property while
restoring. Previously it will first ask DynamicProperty to restore
if possible, then fallback to static property if else.
This patch looks up existing property first, and only fallback to
DynamicProperty if not found. This handles situation when an object
changes an originally dynamic property into a static one. With the
original code, it will add an auto renamed dynamic property that no
one knows its existence.
* distinguish between temp and cache location
* document's transident directory is created in the cache location
* add functions to access temp and cache location via Python
Any object reference inside this function is treated as hidden to
exclude it from dependency calculation. This function allows some form
of cyclic depdenency.
Merger note: renamed from "HREF" to "HIDDENREF" to avoid confusion with
the standard "hypertext reference" use of HREF.
The enumeration items are exposed through sub path '.Enum'. When
'ShowAll' is enabled in property view, this sub path is exposed as a
sub property item named 'Enum', and can be either manually edited or
bound with an expression.
