This is a small library that adds functionality that I have written for other languages in the past and use frequently. I have ported them to a java lib for B4a. The MLStr object should be Dim'ed in Process_Globals.
Dim str As MLStr
Contents:
String Stripto(String line, String find)
Returns the contents of line up to the position of find, with the find character(s) stripped.
The remaining part of the line is returned in remainder. find can be a character or string.
If no match is found, stripto returns "". remainder is a stringbuilder and contains the remainder of the original line with the returned match deleted from it, INCLUDING the character searched for in find.
String Proper(String line)
Uppercases the first letter of each word in line.
returns the propered line "Peter Sellers"
ToHex(long arg)
Converts a long or int number to a hexadecimal string
String Unique()
Returns a unique String composed of the date and time (to the milisecond) in hexadecimal form
String copies(char s, int n)
Returns a string of n number of s characters
String tab(int n)
Returns a string with n number of spaces
int words(String st)
Returns the number of words in a string as an Int
gi will be 4
String wordn(String st, int wordnum)
Returns word number wordnum from the string st as a string.
Returns an empty string if wordnum is more than the word count.
String strip(String Line)
Strips all spaces from Line
String Mirt(String Line)
Trims all spaces from the beginning of the string Line
Useful for parsing strings with stripto
String Escape(String Line)
Escapes all spaces in the string Line.
Required for some file handling methods, especially at the operating system level
This method converts the string:
"This is a test"
to:
"This\ is\ a\ test"
which Linux/Android can then understand.
Comments and suggestions always welcome.

B4X:
Dim txt, tmp As String
txt = "Jem : Miller : Oklahoma City"
txt = stripto(tmp,":") 'will return "Jem " without the ":"
tmp = remainder 'will equal " Miller : Oklahoma City" without the first ":"String Proper(String line)
Uppercases the first letter of each word in line.
B4X:
name = "peter sellers"
name = proper(name)returns the propered line "Peter Sellers"
ToHex(long arg)
Converts a long or int number to a hexadecimal string
B4X:
Dim num As int
Dim hex As String
num = 1354
hex = tohex(num)String Unique()
Returns a unique String composed of the date and time (to the milisecond) in hexadecimal form
B4X:
Dim txt As String
txt = uniqueString copies(char s, int n)
Returns a string of n number of s characters
B4X:
Dim txt As String
txt = copies("*", 8) 'returns "********"String tab(int n)
Returns a string with n number of spaces
B4X:
dim tmp, txt as String
tmp = "Names"
txt = tab(40 - tmp.length) & tmpint words(String st)
Returns the number of words in a string as an Int
B4X:
Dim gi As Int
Dim txt As String
txt = "this is a test"
gi = words(txt)gi will be 4
String wordn(String st, int wordnum)
Returns word number wordnum from the string st as a string.
Returns an empty string if wordnum is more than the word count.
String strip(String Line)
Strips all spaces from Line
String Mirt(String Line)
Trims all spaces from the beginning of the string Line
Useful for parsing strings with stripto
B4X:
Dim tmp, txt As String
tmp = "This is a formatted line "
tmp = stripto(tmp," ")
txt = remainder.tostring 'txt will equal " is a formatted line "
' do something with tmp
tmp = Mirt(txt) 'tmp will equal "is a formatted line "String Escape(String Line)
Escapes all spaces in the string Line.
