Not all unicode characters are allowed as XML output. When writing disallowed characters the SAX parser throws an exception
when loading a project file that results into a broken document and thus to a possible loss of data.
This PR replaces all disallowed characters with an underscore and prints a warning.
This fixes https://github.com/FreeCAD/FreeCAD/issues/22123
Note: It does not fix an already corrupted project file.
At the application level, support the existence of subdirectories inside
the original config and data paths for a specific version of the
software. For a new installation, create them, but for an existing
installation use the most recent available version, even if it's not the
current one (and even if it's not versioned at all). Any migration must
be done at the GUI level due to the amount of data that is potentially
being copied during that process.
Use std::filesystem wherever possible, replacing most uses of
std::string when the object is actually a path. This is the first stage
of refactoring, and does not make any changes to Application that affect
client code. Access to the new directory-handling class is implemented,
but is unused by any external code.
Within code often it is required to temporarly override value of some
object properties. To properly restore old values they must be stored
somewhere and the developer must remember to manualy restore them.
This commit introduces utilities that can be used to make it easier
using RAII idiom to guard the overrides.
* [Core] Fix#15558: Direct expression in ternary operator
* [Core] Added tests for Non-Numeric conditions in ternary op.
* [Core] prevent relational operator chains at grammar level.
* [Core] Rewrite expressions grammar as a layered grammar.
* [Core] Revert to left associative relops (like C/C++) plus tests.
Made several fixes to TaskMeasure:
* Move to correct namespace
* Handle possible exception in update() method
* Add null pointer checks for buttonBox
* Cannot use 'Measure::MeasurePython' as template argument in addObject<>
because the macro PROPERTY_HEADER_WITH_OVERRIDE determines the invalid
string 'App::FeaturePythonT<FeatureT>' so that an exception is raised
Note: The changes might fix issue 20304
* [Core] Add Boolean Functions to expressions (AND, OR, BOOL, NOT)
* [Core] Add `if` function to expressions to overcome ternary operator limitations
* [Core] Update expressions grammar to recognize relational operations as arguments
* [Core] The `if` function has been removed as no consensus was reached regarding its convenience or necessity. Its inclusion was considered potentially confusing or redundant.
* [Core] Make boolean cast based on Confusion threshold.
* Ensure the ::Remove flag of DocumentObject is set to true before calls to breakLinks
* TechDraw: remove then add balloon annotation when changing the SourceView
* Revert "TechDraw: remove then add balloon annotation when changing the SourceView"
This reverts commit 483b4fe4a0715ff63c2669af33fc3beb60a93f54.
* Concatenate all of Document::addObject[s] functions into calls to Document::_addObject
* Fix minor logic errors
* use ::isPerformingTransaction instead of direct operators
* Uniform case for enum
* Remove dupplicate code for Document::removeObject
* Use CamelCase for enum and fix comment
Dimensionless quantities have all exponents equal to zero.
Such quantities are simply numbers. The associated unit is
the unit one, symbol 1, although this is rarely explicitly
written.
See chapter 2.3.3 Dimensions of quantities, The International
System of Units, 9th edition.
Quantity is often queried for Unit just to see if it has a dimension.
Ask Quantity directly using isDimensionless() method and modify that
method not to care about Quantity value validity; no user was ever
asking for value validity.
