Re: pil64 Darwin Port

Hi Axel, asm-pil32 is a project that would allow us to get rid of C-pil32 entirely. not sure it is a good idea. The asm version is inferior to the c version in terms of portability. Cheers, Tomas -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe

Re: picolisp on beaglebone

Hi Alex, If you are in the installation directory (i.e. in a local installation as in your case), start it as ./pil lib/test.l $(/bin/pwd) -bye + It should just print OK if everything is all right. Otherwise it drops into an error handler. got OK, everything works then:-) Thank you,

Re: First class environments (Was: ... dynamic scoping and lambda

Hi Alex, The following example is conceived, a normal application would not use 'X' and 'Y' in that way, but other parts of the form's runtime environment are indeed following this schema. But this example may show what I mean by separating activation of an environment from its execution:

Re: First class environments (Was: ... dynamic scoping and lambda

Hi Alex, What I mean is to separate the _activation_ of an environment from its _execution_. In PicoLisp, the call to 'job' (the activation of the environment) can be in a library, not only the definition. Only this makes it possible, for example, to store code fragments like (foo X Y) as

Re: efficiently building a large list

Hi Joe, Sidebar: Is there a way to disable the interactive session from printing the return of a statement? For example, if I do a (setq ABC L) where L is a million items, I'd prefer the option of not having all million items print on my console. I've worked around this by wrapping it in a

Re: FEXPRs

Hi Alex, FEXPRs a not so very important. They just allow you to avoid having to quote everything. I don't understand all the fuss that is made about them. It is perhaps because they are more powerful than the holy macros. If you don't have a compiler, then it doesn't matter. However, they

Re: PicoLisp SSL Problem

Hi Alex, Yes, but as I tried to explain in my previous mail, it won't work with the application server. It depends on 'httpGate' rewriting parts of the HTTP header, and inserting certain PicoLisp-specific new headers, which would not work if 'httpGate' believes to work unencrypted. Perhaps,
