I wonder if it would no be a better fix to add a parameter for the default value to the macro STRING_TO_INT, to which the variable gets set if the string is empty. Might be more readable code not only to me.
Only issue would be the usage in
STRING_TO_INT(pitchFamily, pitchFamilyInt, "latin at pitchFamily")
as that needs no default value, given that "if (!pitchFamily.isEmpty()) {" already before. But then this code is already now not a perfect match for the macro, as the macro again checks if pitchFamily is empty.
Perhaps that code could be changed from
if (!pitchFamily.isEmpty()) {
int pitchFamilyInt;
STRING_TO_INT(pitchFamily, pitchFamilyInt, "latin at pitchFamily")
to
int pitchFamilyInt;
STRING_TO_INT(pitchFamily, pitchFamilyInt, -1, "latin at pitchFamily")
if (pitchFamilyInt != -1) {
with the new macro.
Just a proposal. Because you will find out that this patch is not complete, there are more places where the original variable will get used uninitliazed, because there is no default value. With the same macro STRING_TO_INT this seems at least true for
int m_svgWidth; //! set by read_ext()
int m_svgHeight; //! set by read_ext()
int m_svgChX; //!< set by read_chOff()
int m_svgChY; //!< set by read_chOff()
int m_svgChWidth; //! set by read_chExt()
int m_svgChHeight; //! set by read_chExt()
All are never initialized if their string is empty. And as the other STRING_TO_* macros seem to follow the same pattern, there is even more to do :)
