I dunno. Things got confusing because people were conflating terms and
standards. "C" is really ambiguous in practice--it could mean any of the C
standards or implementations, or it could mean the imaginary "C" language
grammar that some people erroneously believe C++ supports.

Isn't this almost exactly the point that was being alluded to, before these
tangential points started?

Re: HTML Parser Recommendation

They support C95, but have publicly stated they have no intention to ever
support C99, C11, or any newer C standard. For all intents and purposes,
their C compiler is dead. Their C95 support is complete, so all they do is
make sure nothing breaks.

Occassionaly you do see C99-like features, such as variable argument macros,
the __restrict qualifier, and most recently stdint.h, but these come via
their inclusion in the C++ standard. And sadly C++ has declined to adopt
most of what's new in C99 and C11, including named initializers or compound
literals. In fact, the specifications for <stdbool.h> clash, and C++ refused
to even support the _Bool type native to C.

Basically, C and C++ have diverged. Microsoft knows this, and has basically
chosen to abandon C, though maintaining backward compatability for older
code.

Ah, thanks for clearing that up. I was thinking the whole time that
MSVC did claim to support C, although it was stated so vehemently
that I started to question myself.

Re: HTML Parser Recommendation

Craig Barnes — 2013-05-23T22:40:09

Sure, but some people may expect Lua libraries to stick to the part of C
that MSVC *does* support, regardless of what it claims to be. I was
simply making it clear in case it went against anyone's expectations.
I know very little about MSVC but it wasn't my intention to get into a
political debate.

(a site from Microsoft):

  "Visual Studio 2012
  Visual Studio includes a C compiler that you can use to create
  everything from basic C programs to Windows API applications."

In my eyes, it seems they do claim to support C.

Re: HTML Parser Recommendation

Daniel Silverstone — 2013-05-23T21:52:08

If it's not a C compiler, it shouldn't compile C.  (Note C is not a strict
subset of C++ and you can compile C which is not valid C++ with MSVC).

Fortunately for those who need hubbub etc compiled for WIN32, there is MINGW32.


Sigh.

Coda Highland — 2013-05-23T21:47:43

MSVC doesn't support C99 because it's a C++ compiler. The languages
are divergent. (It DOES support C++11 pretty well.) Sort of silly to
be criticizing a compiler for not supporting something it never
claimed to support.

Not silly to say "well, then that compiler can't compile my code."
Because I wouldn't try to compile it with a FORTRAN compiler, either.

We don't support that, or compilers that can't cope with 13 year old
standards.

Couldn't you just compile it as C++ and add extern"C" where necessary?

You are of course welcome on #netsurf or netsurf-dev if you need any

I, personally, do not quite approve some of design decisions in
busted. (No, I do not want to talk about it — that's mostly taste
things.)

That is IMHO, and maybe busted is great for others, but I reserve the
right to not advertise it in my talks :-)

ldoc documentation?

Bernd Eggink — 2013-05-23T18:00:06

Is there a documentation of ldoc somewhere? I mean, something more 
thorough than what ldoc -h outputs?

One question I can't answer at the moment is the following: In a 
directory containing a set of related sources, is there a way to 
automatically generate an index.html which assembles links to all the 
other html files?

Thanks in advance,
Bernd

The twitter account and therefore the paper.li account should already
listen to the RSS news entries, tweets from that source are prefixed with
"News:". Actually there seems to be a problem with the feed from looking at
the pull logs, where it is timing out since about an hour ago.

Re: Hand over global userdata to LUA-called C-function

Pierre-Yves Gérardy — 2013-05-23T14:52:01

It looks like you could use the registry. It's a table-like object
that's only accessible from C, using the Lua API. A kind of C-side
global store for C-functions.

Put the userdata in the registry when you initialize the interpreter,
and get it from there in the C-functions.

Once per module.

In the example, two distinct modules are beind require()'d.

The cacheing optimization pertaining to multiple inclusions of a given
module is a completely different subject that my example does not
cover...
