Yes, this is a good place, i.e. in the child after a (fork).

Yes, sorry for the confusion! The change in namespace semantics last year was a
serious cut, but namespaces in PicoLisp were relatively new at that time, and
the change resulted in a much more useful and efficient system.

Correct. (local) simply 'reads' the next s-expr in current-namespace-only, so
that all symbols in that expression are created here.

Thus you can either give a single symbol or a list of symbols.

I bit the bullet and refactored, all is good now with the newest version.

Regarding detach, would this be a proper way of doing a server where detach
is optional?:

(de server (P H Detach)
   (setq *Port P P (port *Port) *Home (cons H (chop H)))
   (gc)
   (loop
  (setq *Sock (listen P))
  (NIL (fork) (close P))
  (close *Sock) )
   (when Detach
  (detach))
   (task *Sock (http @))
   (http *Sock) )

Thanks Alex, will try and find the time to refactor all the local calls in
the ext library sources.

Regarding ssl and httpGate, I'm managing proxy forwarding with Nginx these
days (encrypted too) so I could actually just delete them as I don't use
them anymore. I should probably create a small writeup on how to do that
for a typical PL project listening on a non standard port. Nginx has been a
real eyeopener on how heavy Apache is in comparison.

I see (local) [clearHistory clearCache] but I also see (local) loadTxt
loadUrl in android.l?

It is the 'local' call:

   (local num?)


The syntax of 'local' changed last year, it must be

   (local) num?

of

   (local) [num?]

I use '[' and ']' if there is more than one symbol instead of '(' and ')' as a
convention. See @lib/vip.l, @lib/android.l or @lib/gis.l for extensive examples.

This should be fine, but as httpGate and ssl also changed a lot, I would
recommend to do (cd src; make tools gate) and copy these too.

Version 17.12 question / error

[Henrik Sarvell]

Hi,

I just downloaded and complied the 17.12 version in order to get detach
(was using a pre-detach version before).

When I try to run my stuff I get [ext/base.l:9] pico -- Bad symbol namespace

And that file currently looks like this:
https://bitbucket.org/hsarvell/ext/src/31474ae47656ae0c020f7009c9ed14c5cc86cc44/base.l?at=default=file-view-default

Also, I can not see any mention of a breaking change relating to this in
the CHANGES file.

And just to make sure I didn't copy the wrong file or anything (I compiled
in a separate dir and copied on top in the /opt/picolisp/bin/ dir):
