Another stupid coding trick



  • I had way too much time on my hands tonight and so I created a batch file that generates a mandelbrot set.

     It's not perfect because of the lack of floating point, but still...

    code:

    @echo off
    echo mandelbrot batch file by Jonathan Schwartz
    SETLOCAL ENABLEDELAYEDEXPANSION
    SETLOCAL ENABLEEXTENSIONS 
    set MaxX=80
    set MaxY=49
    

    set /a Im = -3000
    rem for each line of image
    for /L %%G in (1, 1, %MaxY%) do (
    set /a Re = -6000
    set thing=
    rem for each pixel in the line
    for /L %%H in (1, 1, %MaxX%) do (
    set /a Zr = !Re!
    set /a Zi = !Im!
    set /a n = 39
    rem 20 iterations
    rem for /L %%I in (1, 1, 20) do (call :thirdloop)
    call :thirdloop
    if !n! == 59 (set /a n = 95)
    call :getcharfrominteger n
    rem echo !n!
    rem echo re!Re!
    set /a Re = !Re! + 9000 / %MaxX%

    	rem echo !Re!
    )
    echo !thing!
    rem echo im!Im!
    set /a Im = !Im! + 6000 / %MaxY%
    

    )
    goto :EOF

    :thirdloop
    rem loop up to 20 times
    set /a index = 0
    :thirdloopbody
    	if !index! GEQ 20 goto :EOF
    	set /a index = !index! + 1
    	set /a a = ^(!Zr! * !Zr!^)/3000
        set /a b = ^(!Zi! * !Zi!^)/3000
    	set /a temp = !a! + !b!
    	rem echo a and b !temp!
    	rem if !temp! LSS 0 set thing=%thing%err
        if !temp! GEQ 12000 goto :EOF
        set /a Zi = ^(!Zr! * !Zi!^)/3000
        set /a Zr = !a! - !b! + !Re!
        set /a Zi = !Zi! + !Zi! + !Im!
        set /a n = !n! + 1
    goto thirdloopbody
    

    rem gets chars in range 39-59 + 95
    rem puts character back into passed in variable
    :getcharfrominteger
    set /a charcode = %1
    if !charcode! EQU 95 goto getcharfromintegerjumparea
    if !charcode! GEQ 39 (
    if !charcode! LEQ 59 goto getcharfromintegerjumparea
    )
    set %1 = ""
    goto :EOF
    :getcharfromintegerjumparea
    goto code!charcode!
    :code39
    set thing=%thing%^'
    goto :EOF
    :code40
    set thing=%thing%^(
    goto :EOF
    :code41
    set thing=%thing%^)
    goto :EOF
    :code42
    set thing=%thing%*
    goto :EOF
    :code43
    set thing=%thing%^+
    goto :EOF
    :code44
    set thing=%thing%^,
    goto :EOF
    :code45
    set thing=%thing%-
    goto :EOF
    :code46
    set thing=%thing%.
    goto :EOF
    :code47
    set thing=%thing%/
    goto :EOF
    :code48
    set thing=%thing%0
    goto :EOF
    :code49
    set thing=%thing%1
    goto :EOF
    :code50
    set thing=%thing%2
    goto :EOF
    :code51
    set thing=%thing%3
    goto :EOF
    :code52
    set thing=%thing%4
    goto :EOF
    :code53
    set thing=%thing%5
    goto :EOF
    :code54
    set thing=%thing%6
    goto :EOF
    :code55
    set thing=%thing%7
    goto :EOF
    :code56
    set thing=%thing%8
    goto :EOF
    :code57
    set thing=%thing%9
    goto :EOF
    :code58
    set thing=%thing%:
    goto :EOF
    :code59
    set thing=%thing%^;
    goto :EOF
    :code95
    set thing=%thing%_
    goto :EOF

  • The only thing that is even less useful than a Mandelbrot set visualizer is an ASCII Mandelbrot set visualizer implemented as a batch script.

    Out of interest, what do the numbers at the edge mean?



  • they're there to try to make the edge look like a mandelbrot edge.

    umm... and what about making mandelbrot set visualizer (zoomable) on excel table, with vba?

    that would be about the same level of usefulness

    A bit more stupid though.

    Except 500% awesome.



  • Ha ha... this is awesome. 

    Lucky for you. My "stupid coding trick" was moved to the Funny Stuff forum almost immediately after I posted it. At least here on the side bar it'll get far more views.

    i'd already try to do it, exept that i have OpenOffice, so no VBA for me 😞

    never thought i would miss it...

    That must have been legendary.

    I know you're somewhat new to posting here, but rezzing a 2 week-old thread to post something like this is gay.

    Well what I had to say was important enough to excuse this breach of ana...err étiquette. Wasn't it?

    No, it was retarded.  You could have sent a PM.

    Nope, in particular since chartre is a) also correct, even though obsolete and b) has other meanings which make it funnier.
