Looks very nice! ...but: is it working?

peter[~]$ ./render.lsp
sh: open: command not found

In the source, I see:

(exec (string "open "(env "HOME") "/Desktop/noname.ps"))

In my Linux environment I do not have a command called 'open'...

really sorry about that, Peter. I had been browsing Lutz's PostScript.lsp code module, lifted out the bits which i could test on my MacOS machine and forgot that you'll probably need to go via GhostScript if you don't have a built-in PostScript interpreter.

lucky I'm not a developer ... :-)

For Windows change Cormullion's render function to this:

Code: Select all

(define (render)
    (write-file "noname.ps" 
        (append [text]%!PS-Adobe-3.1
%%Creator: newLISP
[/text] buffer "showpage" "\r\n")))

and use ghostscript for display of the generated postscript file.

enjoy the meal,

Lutz

Ha! But when did this obsession with cornflakes start? :-)

I think cornflakes will be difficult. Too much PostScript, and not enough newLISP...
