Not at the moment. It is totally focused on PicoLisp :)

Correct.

You could define a 'load>' method for the '+Buffer' class, or just a function as
it is now (as there is only one class).

A function would dispatch in the above way

   (de markup (Lst)
  (if (is-c-or-js-file? (: file))
  ...

A method would make sense if you defined various buffer classes, '+PilBuffer',
'+CBuffer', '+JsBuffer' each with its own 'load>' method (so the above 'if' is
not needed). A new file could be loaded in the default '+Buffer', and the class
changed dynamically if a certain file type is detected. The class could actually
change repeatedly, depending on what vip believes to recognize while you type in
the buffer :)

Interfacing with JavaScript is indeed quite simple.

In addition to the built-in stuff in @lib/form.js (including a JS lisp()
function which calls a Lisp function on the server!), or @lib/canvas.js for
canvas drawing, I interfaced to the TinyMCE editor (also in the distribution, in
@lib/tinymce.l) for some projects, e.g. https://BlitzMenu.7fach.de

Another example are the social privacy buttons (used in picolisp.com or
sushi.7fach.de), available in http://software-lab.de/socialshareprivacy.tgz.

Thanks!

Destructive element modification?

[Christopher Howard]

Hi list. How do I *destructively* modify the value of one element in a
list? E.g.

(setq Lst (1 2 3 4))

How do I set the second element to be 10, without creating a new list,
and without using "con" to change a lot of the list?

Does anyone know the algorithm that is being expressed here?

I am trying to understand the code... http://picolisp.com/wiki/?99p35

BBWT

[Lindsay John Lawrence]

Bijective Burrows Wheeler Transform

https://github.com/thinknlive/picolisp-bbwt

As I was working on this I realized I need to start thinking about how to
organize my code...

The two main functions, encodeBBWT and decodeBBWT feel larger than they
should be because I have defined smaller functions within them that use
variables in the same scope.

My question:  Is there an 'idiomatic' or recommended way to organize module
or project code in picolisp?

/Lindsay

P.S. I haven't paid much attention to namespaces or module management in
picolisp until now so I'll spend some time reading the docs with that in
mind.

Re: Future of PicoLisp?

[Mansur Mamkin]

Hi all!
About certbot:
See also other tools:
https://www.metachris.com/2015/12/comparison-of-10-acme-lets-encrypt-clients/
I've seen acmetool in action (written in Golang, so it requires no 
dependencies).
I see there is a tool, written even in Bash 

Best regards, 
Mansur

Re: Future of PicoLisp?

[Lindsay John Lawrence]

Hi Alex,

I've been using LetsEncrypt.

This page https://gethttpsforfree.com clearly documents the steps to get a
certificate manually.
I ended up writing an automated javascript (nodejs) version of the steps on
that page that works for my purposes but is essentially just 'get it done'
 code.

It should be straightforward to write a picolisp version of it...

Vip and different file types

[Erik Gustafson]

Hi Alex,

Does Vip recognize different file types?

My end goal is for C/Javascript comments to be rendered properly when those
files
are being edited. I think this would only involve a substitute 'markup'
function which
swaps PL comment syntax for C comment syntax to be executed when Vip is
called
with a C/JS file?

Maybe the alternate 'markupC' could be called through 'load>'? Something
like,

   (dm load> ()
  (if (is-c-or-js-file? (: file))
 (markupC
(=: text
   ... )
 (markup   # else markup as normal
... )
 ... )

I haven't made a serious attempt to get it working yet, would the above be
headed in
the right direction?

Thanks,
Erik

Great! I'll reach out to Zed and confirm that this is still kosher.

Sounds like a headache, I don't blame you. I'll be cheering for the Debian

I think we're doing fairly well here. css is very easy to integrate, see
http://picolisp.com/wiki/?css

For html 5, I usually just define the tags I need on a per project basis,
like the other tag functions in the 'lib/xhtml.l', e.g.

   (load "@lib/xhtml.l")

   (de  (Attr . Prg)
  (tag 'section Attr 2 Prg)
  (prinl) )

Henrik and Jose have done work with websockets. See:
https://bitbucket.org/hsarvell/pl-web

But don't let that stop you from running with your own ideas!

and also javascript (json, frameworks, ...)

Now we're talking! I think PicoLisp would pair nicely with some of the
popular libraries and frameworks. Joe built
https://github.com/joebo/pil-mithril-scaffold. A similar project for React
or Vue with a PicoLisp DB would be cool! I
made an attempt with React last year, but did not progress beyond a couple
'Hello World' programs and a clone
of the React Comment Box Tutorial backed by a PicoLisp DB.
https://github.com/erdg/picolisp-react

Anything that could help introduce PicoLisp and its built-in DB to a wider
web-dev audience would be time well
spent, in my mind. I'm happy to collaborate on that front!

I know others have used similar setups in the past (Henrik, was it?). Is
there an existing write-up regarding this?

Re: Future of PicoLisp?

[Jakob Eriksson]

And I would be interested in working on a package or module system similar to 
"pip" for Python.

I must confess that most discussions about namespaces etc on this list is way 
over my head... however could I be on the right track if I were to assume that 
using "local" in such modules would be a good start, so as to only export 
deliberately exposed symbols from a package?
