The restricted layer list contains layer names and layer ids if layer ids are used as service layer name.
This code adds layer short name to the restricted layer list if layer ids are not used as service layer name.
instead of always getting first feature from the layer
This means that e.g. expression builder previews in composer atlas
will use the current atlas preview feature
Also remove an unnecessary restriction that blocks the preview if
a layer has no features
Before, when a field didn't passed the defined constraints
it showed a message in the form of "field name: Constraint defined message".
Now, if if a field alias is defined, the message is in the form of
"field alias: Constraint defined message"
See #15455
TauDEM is quite specific set of tools and it requires installation of
some additional tools. So we decide to turn it into separate provider,
reducing core codebase size and maintenance efforts.
Tagged as feature to not forget mention in changelog and documentation
This adds a new item_variables expression function when expressions
are used inside a composition context.
The function takes a single argument, the id for an item inside
the composition, and returns a map of variable name to value
for that item.
This allows you to do things like insert text in a label fetching
properties of another item in the composition, eg
Insert scale of map into a label:
map_get( item_variables( 'map'),'map_scale')
Insert x coordinate of map center into a label:
x(map_get( item_variables( 'map'),'map_extent_center'))
Intended as a registry for the various processing components,
including providers, algorithms and various parameters and outputs.
Currently handles only registration of providers, as a step toward
removing processing's algList (this requires first porting
the algorithm class to c++)
A QgsProcessingRegistry instance is attached to QgsApplication,
and is retrieved by QgsApplication::processingRegistry()
Nothing particularly exciting here yet, but this commit
moves the definition of the provider base class to a c++
QgsProcessingProvider abstract base class.
As part of this some existing python methods were renamed
to make their use clearer and to fit with the QGIS c++
api conventions:
- getName was renamed to id
- getDescription was renamed to name
- getIcon was renamed to icon
These API breaks are documented
spell check will be done automatically in words by default (when some conditions are fulfilled)
possibility to avoid in words checking by adding :* at the end in spelling.dat
one can add #spellok at the end of a line of code to skip spell check on this line
Returns current locale used by QGIS. By default this is current
system locale. If user enabled locale override in QGIS settings
overriden locale will be returned.
