ScriptForge.String service
The String service provides a collection of methods for string processing. These methods can be used to:Validate the contents of stringsFormat strings by trimming, justifying or wrapping their contentsUse regular expressions to search and replace substringsApply hash algorithms on strings, etc.
Definitions
Line breaks
The String service recognizes the following line breaks:
Symbolic nameASCII number
Line feed
Vertical tab
Carriage return
Line feed + Carriage return
File separator
Group separator
Record separator
Next line
Line separator
Paragraph separator
10 12 13 10 + 13 28 29 30 133 8232 8233
Whitespaces
The String service recognizes the following whitespaces:
Symbolic nameASCII number
Space
Horizontal tab
Line feed
Vertical tab
Form feed
Carriage return
Next line
No-break space
Line separator
Paragraph separator
32 9 10 11 12 13 133 160 8232 8233
Escape sequences
Below is a list of escape sequences that can be used in strings.
Escape SequenceSymbolic nameASCII number
\n \r \t
Line feed
Carriage return
Horizontal tab
10 13 9
To have the escape sequence "\n" interpreted as an actual string, simply use "\\n" instead of "\" & Chr(10).
Non-printable characters:
Characters defined in the Unicode Character Database as “Other” or “Separator” are considered as non-printable characters.Control characters (ascii code <= 0x1F) are also considered as non-printable.
Quotes inside strings:
To add quotes in strings use \' (single quote) or \" (double quote). For example:The string [str\'i\'ng] is interpreted as [str'i'ng]The string [str\"i\"ng] is interpreted as [str"i"ng]
Service invocation
Before using the ScriptForge.String service the ScriptForge library needs to be loaded using:GlobalScope.BasicLibraries.loadLibrary("ScriptForge")Loading the library will create the SF_String object that can be used to call the methods in the String service.The following code snippets show the three ways to call methods from the String service (the Capitalize method is used as an example):Dim s as String : s = "abc def"s = SF_String.Capitalize(s) ' Abc DefDim s as String : s = "abc def"Dim svc : svc = SF_Strings = svc.Capitalize(s) ' Abc DefDim s as String : s = "abc def"Dim svc : svc = CreateScriptService("String")s = svc.Capitalize(s) ' Abc DefThe code snippet below illustrates how to invoke methods from the String service in Python scripts. The IsIPv4 method is used as an example.from scriptforge import CreateScriptServicesvc = CreateScriptService("String")ip_address = '192.168.0.14'svc.IsIPv4(ip_address) # True
Properties
The SF_String object provides the following properties for Basic scripts:
NameReadOnlyDescriptionsfCRYesCarriage return: Chr(13)sfCRLFYesCarriage return + Linefeed: Chr(13) & Chr(10)sfLFYesLinefeed: Chr(10)sfNEWLINEYesCarriage return + Linefeed, which can be 1) Chr(13) & Chr(10) or
2) Linefeed: Chr(10)
depending on the operating system.sfTABYesHorizontal tabulation: Chr(9)
You can use the properties above to identify or insert the corresponding characters inside strings. For example, the Linefeed can be replaced by SF_String.sfLF.
The first argument of most methods is the string to be considered. It is always passed by reference and left unchanged. Methods such as Capitalize, Escape, etc return a new string after their execution.Because Python has comprehensive built-in string support, most of the methods in the String service are available for Basic scripts only. The methods available for Basic and Python are: HashStr, IsADate, IsEmail, IsFileName, IsIBAN, IsIPv4, IsLike, IsSheetName, IsUrl, SplitNotQuoted and Wrap.

This parameter is passed by reference, so after execution the value of start will point to the first character of the found substring. If no matching substring is found, start will be set to 0.casesensitive: The search can be case sensitive or not (Default = False).forward: Determines the direction of the search. If True, search moves forward. If False search moves backwards (Default = True)At the first iteration, if forward = True, then start should be equal to 1, whereas if forward = False then start should be equal to Len(inputstr)Dim lStart As Long : lStart = 1Dim result as Stringresult = SF_String.FindRegex("abCcdefghHij", "C.*H", lStart, CaseSensitive := True)MsgBox lStart & ": " & result'3: CcdefghHIn the example above, the new value of lStart can be used to keep searching the same input string by setting the Start parameter to lStart + Len(result) at the next iteration.

Returns the input string in reversed order.This method is equivalent to the built-in StrReverse Basic function.To use the StrReverse function, the statement Option VBASupport 1 must be present in the module.
svc.Reverse(inputstr: str): str
inputstr: The string to be reversed.MsgBox SF_String.Reverse("abcdefghij") ' "jihgfedcba" SplitLines -------------------------------------------------------------------------------------------- String service;SplitLines
SplitLines
Returns a zero-based array of strings with the lines in the input string. Each item in the array is obtained by splitting the input string at newline characters.
svc.SplitLines(inputstr: str, [keepbreaks: int]): str[0..*]
inputstr: The string to be split.keepbreaks: When True, line breaks are preserved in the output array (default = False).Dim a as Varianta = SF_String.SplitLines("Line1" & Chr(10) & "Line2" & Chr(13) & "Line3")' a = Array("Line1", "Line2", "Line3")a = SF_String.SplitLines("Line1" & Chr(10) & "Line2" & Chr(13) & "Line3" & Chr(10))' a = Array("Line1", "Line2", "Line3", "")a = SF_String.SplitLines("Line1" & Chr(10) & "Line2" & Chr(13) & "Line3" & Chr(10), KeepBreaks := True)' a = Array("Line1\n", "Line2\r", "Line3\n", "") SplitNotQuoted ---------------------------------------------------------------------------------------- String service;SplitNotQuoted
SplitNotQuoted
Splits a string into an array of elements using a specified delimiter.If a quoted substring contains a delimiter, it is ignored. This is useful when parsing CSV-like records that contain quoted strings.
svc.SplitNotQuoted(inputstr: str, [delimiter: str], [occurrences: int], [quotechar: str]): str[0..*]
inputstr: The string to be split.delimiter: A string of one or more characters that will be used as delimiter. The default delimiter is the Ascii space " " character.occurrences: The maximum number of substrings to return. The default value is 0, meaning that there is no limit to the number of returned strings.quotechar: Either the single (') or double (") quote.arr1 = SF_String.SplitNotQuoted("abc def ghi")' arr1 = Array("abc", "def", "ghi")arr2 = SF_String.SplitNotQuoted("abc,""def,ghi""", ",")' arr2 = Array("abc", """def,ghi""")arr3 = SF_String.SplitNotQuoted("abc,""def\"",ghi""", ",") ' arr3 = Array("abc", """def\"",ghi""")arr4 = SF_String.SplitNotQuoted("abc,""def\"",ghi"""",", ",")' arr4 = Array("abc", """def\"",ghi""", "")svc = CreateScriptService("String")arr1 = svc.SplitNotQuoted('abc def ghi')# arr1 = ('abc', 'def', 'ghi')arr2 = svc.SplitNotQuoted('abc,"def,ghi"', ",")# arr2 = ('abc', '"def,ghi"')arr3 = svc.SplitNotQuoted(r'abc,"def\",ghi"', ",")# arr3 = ('abc', '"def\\",ghi"')arr4 = svc.SplitNotQuoted(r'abc,"def\",ghi"",', ",")# arr4 = ('abc', '"def\\",ghi""', '')Beware of the differences between Basic and Python when representing strings. For example, in Basic two "" characters inside a string are interpreted as a single " character. In Python, strings enclosed with single quotes can contain " characters without having to double them. StartsWith -------------------------------------------------------------------------------------------- String service;StartsWith
StartsWith
Returns True if the first characters of a string are identical to a given substring.This method returns False if either the input string or the substring have a length = 0 or when the substring is longer than the input string.
svc.StartsWith(inputstr: str, substring: str, [casesensitive: bool]): bool
inputstr: The string to be tested.substring: The substring to be searched at the start of inputstr.casesensitive: The search can be case sensitive or not (Default = False).MsgBox SF_String.StartsWith("abcdefg", "ABC") 'TrueMsgBox SF_String.StartsWith("abcdefg", "ABC", CaseSensitive := True) 'False TrimExt ----------------------------------------------------------------------------------------------- String service;TrimExt
TrimExt
Returns the input string without its leading and trailing whitespaces.
svc.TrimExt(inputstr: str): str
inputstr: The string to trim.MsgBox SF_String.TrimExt(" Some text. ") ' "Some text."MsgBox SF_String.TrimExt(" ABCDEF" & Chr(9) & Chr(10) & Chr(13) & " ") ' "ABCDEF" Unescape ---------------------------------------------------------------------------------------------- String service;Unescape
Unescape
Converts any escaped sequence (\\, \n, \r, \t) in the input string to their corresponding Ascii character.
svc.Unescape(inputstr: str): str
inputstr: The string to be converted.MsgBox SF_String.Unescape("abc\n\tdef\\n")' "abc" & Chr(10) & Chr(9) & "def\n" Unquote ----------------------------------------------------------------------------------------------- String service;Unquote
Unquote
Removes the single or double quotes enclosing the input string.This is useful when parsing CSV-like records that contain quoted strings.
svc.Unquote(inputstr: str, [quotechar: str]): str
inputstr: The string to unquote.quotechar: Either the single (') or double (") quote (default).Dim s as String' s = "Some text" (without enclosing quotes)s = SF_String.Unquote("""Some text""")' The string below does not have enclosing quotes, so it remains unchanged' s = "Some text" (unchanged)s = SF_String.Unquote("Some text")' Quotes inside the string are not removed' s = "The ""true"" meaning" (unchanged)s = SF_String.Unquote("The ""true"" meaning") Wrap ------------------------------------------------------------------------------------------------- String service;Wrap
Wrap
Converts the input string into an array of substrings so that each item in the array has at most a given number of characters.In practice, this method returns a zero-based array of output lines, without newlines at the end, except for the pre-existing line-breaks.Tabs are expanded using the same procedure performed by the ExpandTabs method. Symbolic line breaks are replaced by their equivalent Ascii characters.If the wrapped output has no content, the returned array is empty.
svc.Wrap(inputstr: str, [width: int], [tabsize: int]): str
inputstr: The string to wrap.width: The maximum number of characters in each line (Default = 70).tabsize: Before wrapping the text, the existing TAB Chr(9) characters are replaced with spaces. The argument tabsize defines the TAB stops at TabSize + 1, 2 * TabSize + 1 , ... N * TabSize + 1 (Default = 8).a = "Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit..."b = SF_String.Wrap(a, 20)' Array("Neque porro ", "quisquam est qui ", "dolorem ipsum quia ", "dolor sit amet, ", "consectetur, ", "adipisci velit...")a = "Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit..."b = svc.Wrap(a, 20)# ('Neque porro ', 'quisquam est qui ', 'dolorem ipsum quia ', 'dolor sit amet, ', 'consectetur, ', 'adipisci velit...')
