ReadDelimitedText() [1/2]

int ReadDelimitedText	(	char *	aDest,
		const char *	aSource,
		int	aDestSize
	)

Copy bytes from aSource delimited string segment to aDest buffer.

The extracted string will be null terminated even if truncation is necessary because aDestSize was not large enough.

Parameters

aDest	is the destination byte buffer.
aSource	is the source bytes as a C string.
aDestSize	is the size of the destination byte buffer.

Returns

the number of bytes read from source, which may be more than the number copied, due to escaping of double quotes and the escape byte itself.

Deprecated:

should use the one which fetches a wxString, below.

ReplaceIllegalFileNameChars() [1/2]

bool ReplaceIllegalFileNameChars	(	std::string *	aName,
		int	aReplaceChar = 0
	)

Checks aName for illegal file name characters.

The Windows (DOS) file system forbidden characters already include the forbidden file name characters for both Posix and OSX systems. The characters \/?*|"<> are illegal and are replaced with xx where xx the hexadecimal equivalent of the replaced character. This replacement may not be as elegant as using an underscore ('_') or hyphen ('-') but it guarantees that there will be no naming conflicts when fixing footprint library names. however, if aReplaceChar is given, it will replace the illegal chars

Parameters

aName	is a point to a std::string object containing the footprint name to verify.
aReplaceChar	(if not 0) is the replacement char.

Returns

true if any characters have been replaced in aName.

split()

static std::vector<std::string> split ( const std::string &  aStr, const std::string &  aDelim  )

Split the input string into a vector of output strings.

Parameters

aStr	Input string with 0 or more delimiters.
aDelim	The string of delimiter. Multiple characters here denote alternate delimiters.

Returns

StrNumCmp()

int StrNumCmp	(	const wxString &	aString1,

		bool	aIgnoreCase = false
	)

Compare two strings with alphanumerical content.

This function is equivalent to strncmp() or strncasecmp() if aIgnoreCase is true except that strings containing numbers are compared by their integer value not by their ASCII code. In other words U10 would be greater than U2.

Parameters

aString1	A wxString reference to the reference string.
aString2	A wxString reference to the comparison string.
aIgnoreCase	Use true to make the comparison case insensitive.

Returns

An integer value of -1 if aString1 is less than aString2, 0 if aString1 is equal to aString2, or 1 if aString1 is greater than aString2.

ValueStringCompare()

int ValueStringCompare	(	const wxString &	strFWord,
		const wxString &	strSWord
	)

Compare strings like the strcmp function but handle numbers and modifiers within the string text correctly for sorting.

eg. 1mF > 55uF

Returns

-1 if first string is less than the second, 0 if the strings are equal, or 1 if the first string is greater than the second.
