Library content
Package Strings contains functions to manipulate strings.
In the table below an example call to every function is given using the default options.
| Function | Description |
|---|---|
| len = length(string) | Returns length of string |
| string2 = substring(string1,startIndex,endIndex) | Returns a substring defined by start and end index |
| result = repeat(n) result = repeat(n,string) |
Repeat a blank or a string n times. |
| result = compare(string1, string2) | Compares two substrings with regards to alphabetical order |
| identical = isEqual(string1,string2) | Determine whether two strings are identical |
| result = count(string,searchString) | Count the number of occurrences of a string |
| index = find(string,searchString) | Find first occurrence of a string in another string |
| index = findLast(string,searchString) | Find last occurrence of a string in another string |
| string2 = replace(string,searchString,replaceString) | Replace one or all occurrences of a string |
| stringVector2 = sort(stringVector1) | Sort vector of strings in alphabetic order |
| hash = hashString(string) | Create a hash value of a string |
| (token, index) = scanToken(string,startIndex) | Scan for a token (Real/Integer/Boolean/String/Identifier/Delimiter/NoToken) |
| (number, index) = scanReal(string,startIndex) | Scan for a Real constant |
| (number, index) = scanInteger(string,startIndex) | Scan for an Integer constant |
| (boolean, index) = scanBoolean(string,startIndex) | Scan for a Boolean constant |
| (string2, index) = scanString(string,startIndex) | Scan for a String constant |
| (identifier, index) = scanIdentifier(string,startIndex) | Scan for an identifier |
| (delimiter, index) = scanDelimiter(string,startIndex) | Scan for delimiters |
| scanNoToken(string,startIndex) | Check that remaining part of string consists solely of white space or line comments ("// ...\n"). |
| syntaxError(string,index,message) | Print a "syntax error message" as well as a string and the index at which scanning detected an error |
The functions "compare", "isEqual", "count", "find", "findLast", "replace", "sort" have the optional input argument caseSensitive with default true. If false, the operation is carried out without taking into account whether a character is upper or lower case.
