[Implemented] gettoken, nexttoken , ...

Some statements like gettoken, nexttoken, ... would be useful.
They can split strings into tokens at certain positions (delimiter-string).
The delimiter-string is a set of characters, which define the positions, where the string will be cut.

Example:
source$ = "This is a text, we will split into substrings."

result$ = gettoken(source$," ,")

will generate the following results after 9 calls:

This
is
a
text
we
will split
into
strings

You can find these statements in JAVA. They are very useful for working with input-streams of any kind.

Hi,

Wonder if your example would work even in JAVA ...

you can do it in PB :

Code: Select all

 
A$ = "this is a test"


Global A$

Procedure.s gettoken( B$, C$ )
  len_B = Len( B$ )
  posit = FindString( B$, C$, 1 )
  If posit > 0
    E$ = Left( B$, posit )
    A$ = Right( A$, len_B - posit )
  Else
    E$ = B$
    A$ = "" 
  EndIf

  
  ProcedureReturn E$

EndProcedure

OpenConsole( )



While Len( A$ )
  D$ = gettoken( A$, " " ) ;
  PrintN( D$ )
Wend
   

Input( )

CloseConsole( )

Hope this helps.

You're absolutly right. The code is NOT Java, but "gettoken" and nexttoken".

Thank you for the help.

What do you need this for? I'm wondering if you're trying to parse the command
line arguments to your app? If so, use the ProgramParameter() command. If not,
I'll just shut up.

commands: GetWord$() and CountWords_()

Very useful for a parser !!

Frederic:
maybe you can take a look and add
GetWord() and CountWords()
directly into PureBasic ??
I need this 2 commands too, and when its included
in PureBasic, its sure i can use it in the future.
(Maybe the addon lib doesnt work anymore, in future
version of PB)
