multi-lingual guile: language strictness

multi-lingual guile: language strictness

[Matt Wette]

Hi All,

I posed a question on #guile IRC last weekend asking for use cases for 
making Guile
multi-lingual.  The use case that came up was the desire to use Guile as 
an extension
that supports multiple languages for users.  To that end, I wonder how 
important it is
to make these extension languages meet published language conventions or 
standards.
I believe to do so is too difficult: the Guile community does not have 
the volunteer
workforce people to achieve this.  I think it would be more practical to 
look for
reasonable approximations.  If this is the direction to go, then should 
Guile name
these extension languages according to what they attempt to mimic (e.g., 
javascript),
or rather rename to something that has a similar sounding name (e.g., 
guavascript), or,
as another option, rename with an extension monicker (e.g., javascriptx)?

Is this possibility for making Guile multi-lingual a promised 
feature,
or more of a wishlist type thing? I'll have to think about some 
ways
that might be good to approach this, because the limiting
volunteer-community is definitely going to be an issue.

It's already a thing.

There are some other user-supplied languages installable as packages,
such as the delightful Wisp and guile-log

Is it possible to call them at the same time, via the C interface?

I would think so.  In general all languages see the same name space.

scheme@(guile-user)> ,L ecmascript
Happy hacking with ECMAScript!  To switch back, type `,L scheme'.
ecmascript@(guile-user)> function foo(x) { return x + 1; };
ecmascript@(guile-user)> foo(1);
$1 = 2
ecmascript@(guile-user)> ,L scheme
Happy hacking with Scheme!  To switch back, type `,L ecmascript'.
scheme@(guile-user)> (foo 1)
$2 = 2

Yes, that is what I asked for, to be able to create objects in one language and interact with the same objects in another.

+1 for a "pidgin-" prefix (somewhat tongue-in-cheek ;-P

Or perhaps "pidguin-"?

But more seriously: I like the "extension" (be it prefix or suffix)
pattern most: people see what's intended and that it isn't the
"real thing".

Cheers

+1 on distinguishing non-conformant implementations, makes life easier
when Guile later supports (whether inbuilt or not) a conforming
implementation of that language.

I guess javascript is the exception to that rule, because Guile's
javascript is probably the closest thing to a conforming ES4
implementation out there.

I like the idea of a consistent suffix or prefix for nonconformant
implementations, even in the guildhall.

Since when is that that the case? The manual page for
ECMAScript (6.24.3) states:

Which make it sound like that implementation is far from
good.
