Typedefs
using	DB_VALUE = std::variant<std::monostate, std::string, int64_t, double, bool>
	A single database cell, where monostate is SQL NULL.

Functions
std::string	DatabaseValueToString (const DB_VALUE &aValue)
	Convert a database value to the text KiCad stores for it.
std::string	DatabaseValueToString (const char *)=delete
	A C string would silently convert to bool, so the caller must build a std::string.
std::string	NormalizeDecimalText (const std::string &aText)
	Trim redundant trailing zeros and a dangling decimal point from decimal text, for example "4700000.0000" becomes "4700000", and add the missing zero to ".5".

DB_VALUE

using DB_VALUE = std::variant<std::monostate, std::string, int64_t, double, bool>

A single database cell, where monostate is SQL NULL.

Function Documentation

DatabaseValueToString() [1/2]

std::string DatabaseValueToString ( const char * )

delete

A C string would silently convert to bool, so the caller must build a std::string.

DatabaseValueToString() [2/2]

std::string DatabaseValueToString

(

const DB_VALUE &

aValue

)

Convert a database value to the text KiCad stores for it.

Doubles use the shortest text that reads back to the same value, booleans become "1" or "0" and NULL becomes an empty string. Strings are returned unchanged.

NormalizeDecimalText()

std::string NormalizeDecimalText

(

const std::string &

aText

)

Trim redundant trailing zeros and a dangling decimal point from decimal text, for example "4700000.0000" becomes "4700000", and add the missing zero to ".5".

A leading sign is kept except that a zero value with a decimal point becomes "0". Text without a decimal point or that is not plain decimal is returned unchanged.
