Detailed Description

NUMERIC_EVALUATOR compatible wrapper around EXPRESSION_EVALUATOR.

This class provides a drop-in replacement for NUMERIC_EVALUATOR that uses the new EXPRESSION_EVALUATOR backend. It maintains the same API to allow seamless migration of existing code.

The key difference is that expressions are automatically wrapped in...} syntax before evaluation.

Example usage:

// Old NUMERIC_EVALUATOR code:
NUMERIC_EVALUATOR eval(EDA_UNITS::MM);
eval.Process("1 + 2");
wxString result = eval.Result(); // "3"
 
// New compatible code:
NUMERIC_EVALUATOR_COMPAT eval(EDA_UNITS::MM);
eval.Process("1 + 2");
wxString result = eval.Result(); // "3"

Member Function Documentation

◆ Clear()

void NUMERIC_EVALUATOR_COMPAT::Clear ( )

Clear parser state but retain variables.

Resets the parser state for processing a new expression. User-defined variables are retained.

Definition at line 1920 of file text_eval_wrapper.cpp.

References m_evaluator, m_lastInput, m_lastResult, and m_lastValid.

Referenced by BOOST_AUTO_TEST_CASE(), and ~NUMERIC_EVALUATOR_COMPAT().

◆ ClearVar()

void NUMERIC_EVALUATOR_COMPAT::ClearVar ( )

Remove all variables.

Definition at line 2064 of file text_eval_wrapper.cpp.

References m_evaluator.

Referenced by BOOST_AUTO_TEST_CASE(), and ~NUMERIC_EVALUATOR_COMPAT().

◆ GetVar()

double NUMERIC_EVALUATOR_COMPAT::GetVar ( const wxString & aString )

Get a variable value.

Parameters

aString Variable name

Returns: Variable value, or 0.0 if not defined

Definition at line 2043 of file text_eval_wrapper.cpp.

References m_evaluator, and result.

Referenced by BOOST_AUTO_TEST_CASE(), and ~NUMERIC_EVALUATOR_COMPAT().

◆ IsValid()

bool NUMERIC_EVALUATOR_COMPAT::IsValid ( ) const

Check if the last evaluation was successful.

Returns: True if last Process() call was successful

Definition at line 1938 of file text_eval_wrapper.cpp.

References m_lastValid.

Referenced by BOOST_AUTO_TEST_CASE(), and ~NUMERIC_EVALUATOR_COMPAT().

◆ LocaleChanged()

void NUMERIC_EVALUATOR_COMPAT::LocaleChanged ( )

Handle locale changes (for decimal separator)

This is a no-op in the EXPRESSION_EVALUATOR implementation since it handles locale properly internally.

◆ OriginalText()

wxString NUMERIC_EVALUATOR_COMPAT::OriginalText ( ) const

Get the original input text.

Returns: The last input string passed to Process()

References m_lastInput.

Referenced by BOOST_AUTO_TEST_CASE(), and ~NUMERIC_EVALUATOR_COMPAT().

◆ Process()

bool NUMERIC_EVALUATOR_COMPAT::Process ( const wxString & aString )

Process and evaluate an expression.

Parameters

aString Expression to evaluate

Returns: True if evaluation was successful

◆ RemoveVar()

void NUMERIC_EVALUATOR_COMPAT::RemoveVar ( const wxString & aString )

Remove a single variable.

Parameters

aString Variable name to remove

◆ Result()

wxString NUMERIC_EVALUATOR_COMPAT::Result ( ) const

Get the result of the last evaluation.

Returns: Result string, or empty if invalid

References m_lastResult.

◆ SetDefaultUnits()

void NUMERIC_EVALUATOR_COMPAT::SetDefaultUnits ( EDA_UNITS aUnits )

Set default units for evaluation.

Parameters

aUnits The default units to use

◆ SetVar()

void NUMERIC_EVALUATOR_COMPAT::SetVar	(	const wxString &	aString,
