Last post by Frank Brübach - April 24, 2024, 09:33:10 PM
Hello all..

Some code example you can find Here and try to use... All example I added in ZIP and rar folder... If you have questions please ASK...

For Testing an example you can Push the "Quick Run" Button .. the Files you can save and load have *.habas endings.

Many thanks Theo for installing this new SUB Board and Charles for His great oxygen Basic language I could study the Last month and years during Corona time and Last year

Dont forget I am Hobby programmer Not  a Professional one.. the IDE iS 80 percent ready
I will improve IT step by step.. at the Moment its all in Interpreter modus

Creation building exe File will come too  IT Works already but I must Test all again

If you are starting the HalPromide24 Type in First some Text in console window to start the the HalPromide  IDE for Further working

I have added minimal Version of HalProment Basic 32 Bit , more will come later

First of all a Pic of the HalPromIde24  and an example with simple calculation

' simple calculation 2
' legend :
' dim = pim, dword = pro
' printy = print
' pstring = string
'
pim a,b,c,d as pro
a= 10 : b=20 : c=40 : d=a*b
printy a
printy d
pstring s = "Hello Batman " + a ' 10
printy s
pstring st = "Hello Spiderman " + d ' 200
printy st

pim k as float
k=2345.67 '2345.6699
printy k

OxygenBasic Examples / Re: Moveable objects qt
Last post by Frank Brübach - April 24, 2024, 02:40:28 PM
Hi Charles

It's Just an Idea how to improve or simplifier a collision for objects Made this fictive Code for consoleG  (Same example Like above)


' fictive code example only an idea for boundingbox for a cube m500 and m400
'
' This example serves for a moving the cube in discrete steps (e.g., one unit at a time)

' Movement logic for cube 500
if key_up_pressed then
    moveCube500(0, 1) ' Move up one unit at a time
elseif key_down_pressed then
    moveCube500(0, -1) ' Move down
elseif key_left_pressed then
    moveCube500(-1, 0) ' Move left
elseif key_right_pressed then
    moveCube500(1, 0) ' Move right
end if

int new_x, newy

' Function to move cube 500 and handle collision
sub moveCube500(int dx, int dy)
    ' Calculate new position
    new_x = cube500_x + dx
    new_y = cube500_y + dy
   
    ' Check for collision with cube 400
    collision = BoundingBoxIntersect(new_x, new_y, cube_width, cube_height, cube400_x, cube400_y, cube_width, cube_height)
   
    ' If no collision, update position
    if not collision then
        cube500_x = new_x
        cube500_y = new_y
    end if
end sub

Advanced Datatypes / Macros for using the Powerbasi...
Last post by Theo Gottwald - April 24, 2024, 10:08:33 AM
🚀 These powerful basic data objects are designed to be very versatile, which is why they use the slower variant data type.

This means they can be used for numbers as well as strings, but the downside is that they are relatively slow.

The object declaration also requires a lot of typing, but at least you can save some time with the macro below. Overall, I think this type of object data type is too slow for many things and therefore not universally applicable.
It also goes against the Power Basic principle of "smaller faster". 💡
#PowerBasic #DataTypes #Versatility #Efficiency


MACRO Make_Stack(P1) = LOCAL P1 AS ISTACKCOLLECTION:P1 = CLASS "StackCollection"  

' Usage:

LOCAL V01 AS VARIANT
LOCAL T01 AS LONG         

Make_Stack(stack)
stack.Push V01 
T01=stack.COUNT
V01=stack.Pop  


MACRO Make_Que(P1) = LOCAL P1 AS IQUEUECOLLECTION:P1 = CLASS "QueueCollection"  

' Usage:
LOCAL V01 AS VARIANT  
LOCAL T01 AS LONG         

Make_Que(queue)

Lets see if Charles agrees to give that person a chance to show up.
And show better culture then last time.
I remember that Jose blocked the person for some reasons.
However I can accept someone who may have changed over time.
I will never accept people with bad behavior or insults in this forum.

Here we are going to ask the same GPT-4 so we can see the result.

Quoteyou are an power basic expert you will deliver ready-to-compile perfectly optimized power basic code this time we will work on formula parser that can calculate the basic mathematics solve brackets and also knows most trigonometric operations split in functions where needed

ChatGPT
QuoteCertainly! We'll build a formula parser in PowerBASIC that handles basic arithmetic operations, solves expressions with nested brackets, and computes common trigonometric functions. The parser will be modular, with separate functions for each type of operation to facilitate readability and maintainability.

Overview of the Parser Design
Tokenization: Split the input string into tokens representing numbers, operators, parentheses, and function names.
Shunting Yard Algorithm: Convert the infix expression (standard notation) to postfix (Reverse Polish Notation, RPN) for easier computation.
Evaluation: Process the RPN expression to calculate the result.
Trigonometric Functions: Include functions for sin, cos, and tan.
We will focus on:

Basic arithmetic: +, -, *, /
Handling parentheses to manage operation precedence.
Trigonometric functions: SIN, COS, TAN (assuming input in radians).
PowerBASIC Code Implementation
First, let's set up the basic structure and tokenization mechanism.


FUNCTION PBMain() AS LONG
    LOCAL expr AS STRING
    expr = "3 + 4 * (2 - 1) + SIN(0.5)"
    PRINT "Result: "; EvaluateExpression(expr)
END FUNCTION

' Function to evaluate the expression
FUNCTION EvaluateExpression(BYVAL expr AS STRING) AS DOUBLE
    LOCAL tokens() AS STRING
    Tokenize(expr, tokens)
    ' Convert to RPN and then evaluate
    LOCAL rpn() AS STRING
    ShuntingYard(tokens, rpn)
    FUNCTION = EvaluateRPN(rpn)
END FUNCTION
Tokenization Function

SUB Tokenize(BYVAL expr AS STRING, tokens() AS STRING)
    LOCAL currentToken AS STRING
    LOCAL ch AS STRING
    FOR i AS LONG = 1 TO LEN(expr)
        ch = MID$(expr, i, 1)
        SELECT CASE ch
            CASE "0" TO "9", "."
                currentToken += ch
            CASE "+", "-", "*", "/", "(", ")"
                IF LEN(currentToken) THEN
                    REDIM PRESERVE tokens(UBOUND(tokens) + 1)
                    tokens(UBOUND(tokens)) = currentToken
                    currentToken = ""
                END IF
                REDIM PRESERVE tokens(UBOUND(tokens) + 1)
                tokens(UBOUND(tokens)) = ch
            CASE ELSE
                IF ch <> " " THEN
                    currentToken += ch
                END IF
        END SELECT
    NEXT
    IF LEN(currentToken) THEN
        REDIM PRESERVE tokens(UBOUND(tokens) + 1)
        tokens(UBOUND(tokens)) = currentToken
    END IF
END SUB


Shunting Yard Algorithm for Handling Operators and Parentheses

SUB ShuntingYard(BYVAL tokens() AS STRING, rpn() AS STRING)
    LOCAL stack AS STRING
    LOCAL token AS STRING
    LOCAL outQueue AS STRING
    ' Implementation of the shunting yard algorithm
    ' [Implementation goes here]
END SUB

RPN Evaluation Function

FUNCTION EvaluateRPN(BYVAL rpn() AS STRING) AS DOUBLE
    LOCAL stack AS DOUBLE
    ' Evaluate the RPN expression
    ' [Implementation goes here]
END FUNCTION

Adding Trigonometric Functions

QuoteThis is the outline for your formula parser. We need to fill in the ShuntingYard and EvaluateRPN functions to complete the parser. If you have specific preferences for handling trigonometric functions or any other specifics, please let me know, and we can adjust the implementation accordingly.

User
Please complete this funtion make it ready to compile:

FUNCTION EvaluateRPN(BYVAL rpn() AS STRING) AS DOUBLE
    LOCAL stack AS DOUBLE
    ' Evaluate the RPN expression
    ' [Implementation goes here]
END FUNCTION


ChatGPT
QuoteTo complete the EvaluateRPN function for evaluating an expression in Reverse Polish Notation (RPN), we will implement a stack-based evaluation approach. Here's how it works:

Traverse the RPN expression token by token.
Push operands (numbers) onto a stack.
When an operator or function token is encountered, pop the required number of operands from the stack, apply the operator or function, and push the result back onto the stack.
Continue until the entire RPN expression has been processed. The value remaining in the stack will be the result of the expression.
Here's a detailed implementation of the EvaluateRPN function, which is ready to compile and integrate with the rest of your PowerBASIC code:

FUNCTION EvaluateRPN(BYVAL rpn() AS STRING) AS DOUBLE
    LOCAL stack(1 TO 256) AS DOUBLE   ' A stack to hold operands
    LOCAL sp AS LONG                  ' Stack pointer
    LOCAL token AS STRING             ' Current token
    LOCAL op1, op2 AS DOUBLE          ' Operands for calculations

    FOR EACH token IN rpn
        SELECT CASE token
            CASE "+", "-", "*", "/"
                IF sp < 2 THEN
                    ? "Error: Insufficient values in the expression"
                    EXIT FUNCTION
                END IF
                op2 = stack(sp): sp = sp - 1
                op1 = stack(sp): sp = sp - 1
                SELECT CASE token
                    CASE "+"
                        stack(sp + 1) = op1 + op2: sp = sp + 1
                    CASE "-"
                        stack(sp + 1) = op1 - op2: sp = sp + 1
                    CASE "*"
                        stack(sp + 1) = op1 * op2: sp = sp + 1
                    CASE "/"
                        IF op2 = 0 THEN
                            ? "Error: Division by zero"
                            EXIT FUNCTION
                        END IF
                        stack(sp + 1) = op1 / op2: sp = sp + 1
                END SELECT
            CASE "SIN", "COS", "TAN"
                IF sp < 1 THEN
                    ? "Error: Insufficient values for the function"
                    EXIT FUNCTION
                END IF
                op1 = stack(sp)
                SELECT CASE token
                    CASE "SIN"
                        stack(sp) = SIN(op1)
                    CASE "COS"
                        stack(sp) = COS(op1)
                    CASE "TAN"
                        stack(sp) = TAN(op1)
                END SELECT
            CASE ELSE
                ' Assume the token is a number and push it onto the stack
                sp = sp + 1
                stack(sp) = VAL(token)
        END SELECT
    NEXT

    IF sp <> 1 THEN
        ? "Error: The RPN expression is invalid."
        EXIT FUNCTION
    END IF

    FUNCTION = stack(1)  ' The result is the only item left on the stack
END FUNCTION

QuoteThis implementation assumes that the RPN array passed to the function is properly formatted and all tokens are valid. The function checks for common errors such as insufficient operands for operators and division by zero. Error handling is minimal and prints error messages to the console.

You can now integrate this function into your formula parser project in PowerBASIC, ensuring that your RPN array generation and tokenization processes align with the requirements of this evaluation function.

Please also complete this function, ready to compile:

To implement the Shunting Yard algorithm, we'll be managing operators, operands, and parentheses to convert an infix expression (standard mathematical notation) into postfix notation (Reverse Polish Notation, RPN). This process will use a stack to hold operators and a queue for the output.

The key steps in the Shunting Yard algorithm include:

Handling operators and applying the correct precedence and associativity.
Managing left and right parentheses to correctly group operations.
Handling function tokens by treating them similarly to parentheses.
Here's a complete and ready-to-compile implementation of the Shunting Yard subroutine for use in PowerBASIC:

SUB ShuntingYard(BYVAL tokens() AS STRING, rpn() AS STRING)
    DIM stack(1 TO 256) AS STRING   ' Stack to hold operators and function tokens
    DIM sp AS LONG                  ' Stack pointer
    DIM output() AS STRING          ' Output queue for RPN tokens
    DIM opCount AS LONG             ' Counter for output array
    LOCAL token AS STRING
    LOCAL topToken AS STRING

    ' Loop through each token in the input array
    FOR EACH token IN tokens
        SELECT CASE token
            CASE "+", "-", "*", "/"
                DO WHILE sp > 0 AND AlsoHigherPrecedence(stack(sp), token)
                    ' Pop from stack to output
                    opCount = opCount + 1
                    REDIM PRESERVE output(opCount)
                    output(opCount) = stack(sp)
                    sp = sp - 1
                LOOP
                ' Push the current operator onto the stack
                sp = sp + 1
                stack(sp) = token
            CASE "("
                ' Push "(" onto stack
                sp = sp + 1
                stack(sp) = token
            CASE ")"
                ' Pop from stack to output until "(" is encountered
                DO WHILE sp > 0 AND stack(sp) <> "("
                    opCount = opCount + 1
                    REDIM PRESERVE output(opCount)
                    output(opCount) = stack(sp)
                    sp = sp - 1
                LOOP
                IF sp = 0 THEN
                    ? "Error: Mismatched parentheses"
                    EXIT SUB
                END IF
                sp = sp - 1  ' Pop the "("
            CASE ELSE
                ' Assume the token is a number or a function name; push directly to output
                opCount = opCount + 1
                REDIM PRESERVE output(opCount)
                output(opCount) = token
        END SELECT
    NEXT

    ' Pop all operators from the stack to the output
    DO WHILE sp > 0
        opCount = opCount + 1
        REDIM PRESERVE output(opCount)
        output(opCount) = stack(sp)
        sp = sp - 1
    LOOP

    ' Copy output to rpn array
    REDIM rpn(1 TO opCount)
    FOR LONG i = 1 TO opCount
        rpn(i) = output(i)
    NEXT
END SUB

' Helper function to determine precedence
FUNCTION AlsoHigherPrecedence(BYVAL stackOp AS STRING, BYVAL incomingOp AS STRING) AS LONG
    FUNCTION = ((stackOp = "*" OR stackOp = "/") AND (incomingOp = "+" OR incomingOp = "-")) OR (stackOp = incomingOp AND (stackOp = "*" OR stackOp = "/"))
END FUNCTION
This subroutine:

Handles basic arithmetic operations with correct precedence rules.
Manages parentheses for grouping expressions.
Directly places numbers (or function results, not handled in this specific implementation but can be added similarly) into the output queue.
Make sure to adjust this example according to the specific rules and operations your parser is supposed to handle, especially if you add more complex functions or operations.

User
After this I ask GPT-4 to give me the complete final code for the parser.
QuoteSure, let's consolidate and provide a complete, ready-to-compile PowerBASIC program that includes all the components discussed earlier for the formula parser.
