canvas.bac

[basica]

Great new stuff to try out. Thanks for creating.

When run on 3.1, canvas.bac gave me this error..

In file included from baconshell.bac.c:2:0:
baconshell.bac.h:388:33: error: expected ')' before 'long'
In file included from baconshell.bac.h:645:0,
                 from baconshell.bac.c:2:
baconshell.PEN.h:3:33: error: expected ')' before 'long'
make: *** [baconshell.bac.o] Error 1

Looking at the PEN sub.

SUB PEN(size#, flag)

    IF flag THEN
        glEnable(GL_POINT_SMOOTH)
        glEnable(GL_LINE_SMOOTH)
    ELSE
        glDisable(GL_POINT_SMOOTH)
        glDisable(GL_LINE_SMOOTH)
    ENDIF
    glPointSize(size#)
    glLineWidth(size#)

ENDSUB


Seems to be correct ---
    IMPORT "glPointSize/Width(float)" FROM lib$ TYPE void

I notice that if I change the size# (float) to just size, there's no error.

Puzzled.

Hi basica,

You're running the canvas context from the BaCon scratchpad in BaConGUI, right?

Did you copy and paste everything correctly? Because this line you are mentioning:


IMPORT "glPointSize/Width(float)" FROM lib$ TYPE void

...does not seem correct to me.

When I copy and paste all canvas code into the scratchpad I do not receive any errors... can you describe exactly what you are doing when using 'canvas.bac'?

Thx
Peter

Peter,

Thanks for your reply.  This item below....

IMPORT "glPointSize/Width(float)" FROM lib$ TYPE void

was my lame shorthand for-

IMPORT "glPointSize(float)" FROM lib$ TYPE void
IMPORT "glLineWidth(float)" FROM lib$ TYPE void
The canvas.bac code I pasted to both the scratchpad, and main program, is correct, and produces the same above error for the PEN function. Same error if canvas.bac is  INCLUDED.

I guess I'm alone here

Are you sure that you're using BaConGUI 3.1, and not a pre 3.0.1 version? Because the recognition of '#' as double is available since 3.0.1.

Peter,

Thanks for looking into this. I definitely have BaConGUI 3.1.

If I remove the PEN sub or redefine "size#" to "size" everything works. The other subs using the '#" notation do not err.

(hmm. maybe this is caused by schools no longer teaching cursive penmanship

Hi basica,

Well, I am puzzled - it simply should work, nobody else experiences this error. Could it be that you're using a beta version of 3.1? Because these beta versions did not mention their beta status (e.g. you'll not see from the version number that you're actually using a beta).

Apart from the simple advise to reinstall BaConGUI 3.1 from scratch, you could also try to install the latest beta and try again.

Or you could post the temporary c/h code files in a tar.gz , so I can take a look at the generated sources? Because unfortunately, I cannot reproduce your problem...

Peter,

Thank you for your help. I've done all of your suggestions and can't seem to rid myself of that PEN error. Attached is a tar of the /tmp files when running the bacongui with canvas-1.3.bac pasted in the main window.

Basica

Hi basica,

Thanks for your files, I found the reason for this issue. It does not happen with the shell version or BaCon version, only the GUI version 3.1 suffers from this problem. I have installed 3.1 in a temporary location and I can see that it does not recognize the '#' suffix when used in the beginning of an argument list.

However, it turns out that I accidentally already fixed the problem in the beta release. It is the last fix "arguments to SUB/FUNC could not contain array with dimension (BaCon and BaConGUI version)" which solves this problem. Therefore I could not reproduce the issue.

So, if you install the latest beta it should work.

Peter,

Bingo.. I downloaded, compiled, and ran the Bacon-3.1.1 beta as you suggested - pasted canvas-1.3 in the scratchpad and "yes" it ran smooth as silk

Again, it amazes me how you can keep such a keen grasp on all these aspects.

Many thanks,
basica
