QgsNumericFormat subclasses provide a means to format a numeric value
as a string, applying various formatting options. E.g. a default
string to value formatter (included here) includes settings for
controlling the number of decimal places, whether a thousands separator
should be shown, whether a leading + sign should be shown, whether
trailing zeros should be shown.
This PR also includes a formatter for bearings, allowing various
formats of numeric bearings to be applied (e.g. control over decimal
places, etc + control over whether direction E/W suffixes are shown,
or whether values should be limited to either the +/- 180 range or
0-360 degree range)
When formatting values, a QgsNumericFormatContext class is used
to provide context. Currently, this includes the thousands and
decimal separators to apply when formatting (which are taken by
default from the user's locale).
A registry of formatters is included to allow easy addition of
other formats in future (e.g. currencies, percentages, scientific
notation, etc...) and to allow plugin based formats.
The intention is to follow this up with gui configuration widgets
for the formats, and then expose them in various places through
the qgis ui (e.g. in the range editor widget for fields, in scalebar
numbers, as an option for formatting numeric labels, etc)
So that these files are all grouped together, making it easier to locate
all the components of the labeling engine and hopefully making things
easier to navigate
the file was manually added later to the installted headers, but not on mac
it is not possible to install a file in a Headers subfolder within a framework if the original header is not in the same cmake current directory
installing a header in a subdirectory is achieved by setting the MACOSX_PACKAGE_LOCATION property of the source file
but setting a property can only be achieved if it is in the same cmake directory (from the docs: Source file properties are visible only to targets added in the same directory [0])

... you are too slow and QJson API is so ugly.
Now using this wonderful json lib:

Results in release mode (QJson tests are not shown but
QJson was even slower than string concat).

Similarly to raster calculator, mesh calculator can take dataset groups from current mesh layer and
combine them with various aritmentic/logical operators to new dataset group.
Adds a new interface QgsAbstractValidityCheck which defines
a single "check" which can be performed on a given QgsValidityCheckContext.
A new application-wide QgsValidityCheckRegistry registers
and manages instances of all known checks, and allows running
of all registered checks of a specific type at once.
Initially the framework is focused toward print layout validity
checks, but the interface has been designed to be generic enough
to allow alternative types of validity checks (e.g. project save
validity checks, processing model validity checks, etc.).
The API is designed to be used both by internal validity checks
and also to be extended by custom, organisation-specific
validity checks. E.g., for print layout validity checks we could have:
Causes sip to generate the type hinting stub (".pyi") files
alongside the generated python modules.
This allows editors like PyCharm to become aware of the
types of objects returned by functions, making the autocompletion
much more useful (e.g. by showing all the members available
for a returned type). It also fixes a bunch of incorrect
warnings highlighted in PyCharm for things like calling
static methods in a class (and, generates some new, but valid,
warnings when unexpected types are passed to functions!)
TODO: work out why PyCharm can't show the docstrings
for methods when the pyi file is present.
Introducting MDAL, QgsMeshLayer, mesh data providers (mesh_memory, mdal)
to read and visualize raw meshes: vertices and faces. Support dragging
2dm files from browser on canvas to visualize 2dm meshes.
Support for QgsMeshLayer in Python API.
