Unable to import (ice-9 psyntax)

Unable to import (ice-9 psyntax)

[Robby Zambito]

Hello,

For some reason I am having trouble importing the (ice-9 psyntax)
module. Whenever I try to import it, I get the following error:

scheme@(guile-user)> (import (ice-9 psyntax))
While compiling expression:
No variable named syntax? in #<module (#{ g122}#) 7f539f071320>

I have Guile 3.0.9 installed from Guix, running on x86_64. I've tried
using a Guix pure container, importing it transitively through R7RS
libraries rather than directly in the REPL. All yield the same error.

Any ideas would be appreciated :)

Robby

Questions:

   * is /usr/local/lib/guile/3.0/ccache present in %load-compiled-path?
   * does /usr/local/lib/guile/3.0/ccache exist?
   * does /usr/local/lib/guile/3.0/ccache/ice-9/psyntax.go exist?
   * is /usr/local/lib/guile/3.0/ccache/ice-9/psyntax.go newer than
     /usr/local/share/guile/3.0/ice-9/psyntax.scm going by mtime?

Greetings,
Maxime

 From the information you have given me, I can't tell which one is 
newest.  You'll need to provide the milliseconds or more precise.

I think this line of questioning is irrelevant -- see other e-mail, and 
also I can reproduce the 'compiling .../psyntax.scm' thing.

This is an undocumented module; you aren't supposed to import it 
directly.  In fact, looking at the first few lines of ice-9/psyntax.scm, 
ice-9/psyntax.scm is part of the (guile) module; there does not exist a 
separate (ice-9 psyntax) module:

   (eval-when (compile)
     (set-current-module (resolve-module '(guile))))

The only use of psyntax is in ice-9/boot.scm:

module/ice-9/boot-9.scm:;; $sc-dispatch is an implementation detail of 
psyntax. It is used by
module/ice-9/boot-9.scm:(primitive-load-path "ice-9/psyntax-pp")

... and that uses ice-9/psyntax-pp.scm, not ice-9/psyntax.scm (the 
former is generated from the latter when Guile itself is compiled).

What are you trying to import (ice-9 psyntax) for?

Greetings,
Maxime.

I am trying to write a portable R7RS library which does a relative
include for its implementation. The code can be found here:
https://git.robbyzambito.me/robby/meta-json.git/tree/lib/zambyte/meta/json.sld?id=334e09f3388a74b5982138b57abb2021e12cf598#n66

The include-library-declarations (and include) in Guile work relative to
the working directory rather than from the calling file (contrary to the
documentation in the Guile manual), which is not desireable for a
library. Instead I'm trying to use include-from-path, which is defined
in (ice-9 psyntax). The problem is that include-from-path seems to be
available by default in Guile, but it was undefined when I was using it
in my R7RS library.

Asking your question made me realize (ice-9 psyntax) does not actually
export include-from-path though. In a nearly complete shot in the dark,
I instead imported (only (guile) include-from-path), which actually does
the trick!

https://git.robbyzambito.me/robby/meta-json.git/tree/lib/zambyte/meta/json.sld?id=7bf0fa24e0df6949d2e1f6c57fb67539d674810a#n67

This works as I wanted :)

Thanks,
Robby
