Replace the int of the 'resolve' argument of several functions with a proper enum class.
* This avoids the inconsistencies in client code where often true/false is passed when an int is expected
* This avoids the use of magic numbers like 0, 1, 2 or the undocumented 3
If package.xml metadata file exists, it is scanned for FreeCAD version
compatibility before the Addon is loaded. If the Addon specifies that it is
explicitly not compatible with the current version of FreeCAD, the Addon is
not loaded.
* If all column vectors of the 3x3 sub-matrix are equal the function incorrectly claims that it's uniform scaling.
* Detect also non-uniform scaling and if was applied from the left or right side
* Replace the int with an enum and expose it to Python
* Add several new unit tests
Addon Manager: Dependency Installation
The Addon Manager can now attempt to use pip directly to install
required packages as specified in either metadata.txt or
requirements.txt files provided by AddOns. The packages are installed
into FreeCAD.getUserAppDataDir()/AdditionalPythonPackages directory.
Only simplified requirements.txt data is supported: any version
information is stripped out, and only packages are supported (that is,
no pip arguments, included files, etc.). Further, packages are checked
against a list of allowed packages prior to being suggested for
installation. Addon authors should submit a PR to the FreeCAD repo
adding their requirements to the allowed list, for packages that are not
already on the list (this is a malware-prevention mechanism).
- this is necessary to perform electrodynamics simulations. Since the typical values are in the range of 1e6 S/m, we need the new units kS and MS
- since this is for simulations, also add electrical conductivity to the FEM material cards
LGTM flagged several redundant imports, and was confused by the else
clause of one loop. This commit removes those imports, and because of
the loop's construction, removes the else entirely and lets the loop
fall through to the error state if it fails to find what it's looking
for.
* Better module import error handling
* Allow co-installation of Python2 and Python3 version of FreeCAD
* Add FreeCAD.Logger class for convenient logging in Python. See class
document for more details.
