Jan 8, 2014 Replies: 6 This is a new version of my old MLStr strings library. it includes methods to find and retrieve whole words from a string as well as some methods that I use a lot in b4a and other languages. It is small and a bit specialized, but quite useful. A test app is included in the zip. Unzip the file and copy MLStr.jar and MLStr.xml to your additional libraries directory. Unzip the mlstrtest.zip somewhere. Then refresh from the IDE libs tab (right click in that panel) if b4a is already running, or just start b4a and open the Strtst project. Current version is 2.2.0 MLStr Author: Jem Miller Version: 2.2 MLStr Fields: Remainder As String Methods: IsInitialized As Boolean Tests whether the object has been initialized. AposCheck (var As String) As String Checks to see if the string "var" contains apostrophies. If so, it puts them in a set of single quotes This is primarily for SQL statements. Copies (inp As String, num As Int) As String Returns a string of "num" occurances of "inp" copies("*",5) will return 5 *'s Escape (Str As String) As String Escapes the spaces in a stirng. Primarily used for file paths like C:\Program Files (x86) or other paths with spaces tmp = str.Escape(tmp) if used with the path above will return: C:\Program\ Files\ (x86) which is linux (and android) friendly. getWords (StartWord As Int, NumWords As Int, Str As String) As String This method ignores punctuation Punctuation is defined as any character not in a-z, A-Z, or 0-9 all punctuation is counted as a word break like a space st = getWords(2,5,"(this is)a test_of my-lib") Returns "is a test of" getwords2 (StartWord As Int, NumWords As Int, Str As String) As String Returns NumWords form Str beginning at StartWord Returns "" if StartWord > total words in Str or if Str = "" Word count begins at 1 and not 0. if NumWords > the number of words remaining in the line, the remainder of the line is returned from StartWord count In this method, only spaces are used as word breaks st = getwords2(2,5,"(this is)a test_of my-lib") Returns "is)a test_of my-lib" hex (numb As Int) As String Returns the hex string value of a number initialize As String Initializes the MLStr object. isChar (ch As Char) As Boolean Checks to see if a character is a normal character (a-z, A-Z, or 0-9) isPunct (ch As Char) As Boolean Checks to see if a character is punctuation (not a-z, A-Z, or 0-9) LastPos (Find As Char, Str As String) As Int Returns the last position of "Find" in "Str" NewLines (num As Byte) As String Returns "num" occurances of CRLF. This is useful for formatting text files newlines(3) returns 3 linefeeds PosWord (wordNum As Int, Str As String) As Int Returns the character postion of the first letter of the Word at postion NumWord i = PosWord(4,"This is a test test of the MLStr-library") returns 11 (the first letter of the word test) Returns 0 if error PosWord2 (wordNum As Int, Str As String) As Int Returns the character postion of the first letter of the Word at postion NumWord i = PosWord2(4,"This is a test test of the MLStr-library") returns 11 (the first letter of the word test) Returns 0 if error This method uses spaces as word breaks. Proper (line As String) As String Uppercases the first letter of EACH word in a string Strip (line As String) As String Strips ALL spaces from "line" StripIt (line As String, ch As Char) As String Strips all occurances of the character "ch" from the string "line" StripTo (line As String, find As String) As String Returns everything in the string "line" up to the point where it finds the string "find". Deletes everything before "find" and returns what is left in the Remainder string. Find can be a single character or a string. stripto("this is a string"," ") will return "this" and Remainder will equal "is a string" Notice that the " " is gone from the return value AND in Remainder. This is true of all find values sent to the routine. The find value is always deleted. Unique As String Returns a unique identifier based on the current date and time converted to hex wordcnt (Str As String) As Int Same as words wordcnt2 (Str As String) As Int Same as words2 WordN (st As String, nm As Byte) As String Returns word number "nm" from string "St" wordn("this is a test",3) will return "a" This method accounts for non- letters and non-numbers WordN2 (st As String, nm As Byte) As String Returns word number "nm" from string "St" wordn2("this is a test",3) will return "a" This method only only uses spaces to break words. Words (st As String) As Int Returns the number of words in "St" words("this is a test") will return 4. This method accounts for punctuation including all non-letters or non-numbers Words2 (st As String) As Int Returns the number of words in "St" words2("this is a test") will return 4. This method uses spaces as word breaks Version 2.0 - Initial release Version 2.1 - Adds the Escape method that I forgot in v2.0 and fixes a bug in the StripTo method that did not properly handle strings as the Find target. Version 2.20 - Adds new methods for using only spaces as word breaks. I didn't realize how many times I need to use spaces as breaks and ignore punctuation such as hyphens. ---Jem Attachments MLStr-2.2.zip MLStr-2.2.zip 16.4 KB · Views: 704 Last edited: Mar 10, 2014 Click to expand...

HotShoe Well-Known Member Licensed User Longtime User Mar 10, 2014 #4 New version 2.20 is attached to first post. I added new methods to use only spaces as word breaks. I found I use this a lot in my coding and when I made the methods punctuation aware, it broke many of my coded routines. --- Jem

MolsonB Member Licensed User Longtime User May 6, 2015 #7 Doh... I was using a different library for string functions and got away with not initializing it (by mistake). This librabry replaced it, but didn't like not being initialized. Thanks for the catch.
