Function Documentation

egsTokenize()

vector<string> egsTokenize

(

const string &

inp

)

Tokenize a string into individual tokens.

Splits the input string into tokens separated by whitespace or commas. Multiple consecutive whitespace characters are treated as a single separator. Commas are converted to spaces before tokenization.

Parameters

str	The input string to tokenize

Returns

A vector of strings containing the individual tokens

Note

Returns an empty vector if the input string is empty

Example:

auto tokens = egsTokenize("1,2   3-5, 6");
// Result: {"1", "2", "3-5", "6"}

egsParseIntegerRanges()

vector<int> egsParseIntegerRanges	(	vector< string >::const_iterator	begin,
		vector< string >::const_iterator	end
	)

Parse integers and integer ranges from string tokens.

Parses a sequence of string tokens, where each token can be either:

• A single integer (e.g., "42")
• An integer range using hyphen notation (e.g., "10-15")

Ranges are expanded to include all integers between the bounds (inclusive). The order of range bounds doesn't matter (e.g., "15-10" works the same as "10-15").

Parameters

begin	Iterator to the first token to parse
end	Iterator one past the last token to parse

Returns

Sorted vector of unique integers with duplicates removed

Note

Invalid tokens (non-numeric strings) are silently ignored

The returned vector is automatically sorted and deduplicated

Examples:

vector<string> tokens = {"5", "10-12", "8", "10"};
auto result = egsParseIntegerRanges(tokens.begin(), tokens.end());
// Result: {5, 8, 10, 11, 12}
 
vector<string> tokens2 = {"20-15", "invalid", "18"};
auto result2 = egsParseIntegerRanges(tokens2.begin(), tokens2.end());
// Result: {15, 16, 17, 18, 19, 20}
