Can ruby replace c?
cmk...@hotmail.com
Can ruby replace c ? Or no, because ruby is a high level language !!
Can ruby write inline assembly?
Does ruby have linker script, so i can link any piece to a specific
address, i need this often in driver programming.
In c, if i declare char[100], it consume 100 bytes, if in ruby, does
it have a datatype that represent one byte? I heard everything in ruby
is object, no exception, so the answer should be no.
Does ruby have pointer? a cpu-specific pointer? In 32 bit CPU,
pointer is 32 bits, in 16 bit CPU, pointer is 16 bits.
thanks

Perhaps when Matz and the team rewrite Ruby in Ruby.
If anybody could do that... it would be them. ;-)

Ruby is an interpreted high level language. You can do a lot of C-like things
in Ruby, but due to performance reasons, Ruby won't replace C, at least until
we have an extremely efficient compiler. It is a perfect language for many
things however.

IIRC there is a project that allows incline C or assembly code. Someone
with more specific memory out there?

Well, you can write C extensions. And there you can do pretty much
everything C allows (if you respect some caveats, as mem allocation etc.).

This is the closest you can get
s = "\000" * 100

No. And you don't need them and cannot use them in Ruby. You would have
to deal with this in an extension.

So there are quite a few iterations left before C will become Ruby (and,
given that D has been around for quite some time and hasn’t become even
close to finished, I’m guessing that the answer is “no”),

Windows is problematic since you'll need the compiler you built Ruby with
for the RubyInline stuff to work.
It's just fine on Mac's and other unix/linux boxen though.

'just fine' is an understatement though- this is a seriously under-rated
project!
cheers.

This one really cracked me up! The first time I see a joke written in a

While programming in Alpha may be problematic, when combined with Omega
it gives you a great amount of power.

No, it should work on Windows too provided you built your own Ruby.
You may need to set some ENV vars as well (like HOME or INLINE_DIR).

just didn't try hard enough.
The problem appears to be that it isn't picking up msvcrt-ruby18.lib
on the LINK step. It compiles when I copy the cl command line from the
error output and add the lib like so:
cl -nologo -LD -MD -Zi -O2b2xg- -G6 -I
c:/ruby/lib/ruby/1.8/i386-mswin32 -o Inline_MyTest_cb89.so
Inline_MyTest_cb89.c msvcrt-ruby18.lib -link /INCREMENTAL:no
/EXPORT:Init_Inline_MyTest_cb89
(with c:\ruby\lib added to the LIB environment variable) but how do I
get RubyInline to do this?
Any pointers anyone? (I'd love to play with this)

The C builder has API to do this:
class X
inline(:C) do |builder|
builder.add_link_flags "whatever"
# ...
end
end
It is fairly well documented. Just generate the rdoc and poke around.
The better route to go is to build your own ruby and it'll pick up
all the things it needs automatically.
Read rbconfig.rb for where we get all our building information.

Some have already started with Hebrew letters:

Some people would, it seems:

Can't find Alpha but Alphard exists:

Anyway, since we have Unicode we shouldn't feel limited to the Latin alphabet.
Let's make a language named after a Tibetan letter! ;)

Yes, it is actually very nice. If it were more widespread, I'd
probably still program in it. It has some nice syntactic sugar.

Z does exist but is a program specification language, a terrible thing
that you learn in university. Eiffel is a real language based on Z. So
we are just adding one or two more letters to the language name.

So *that's* why I found Eiffel so awful when I looked at it!
For what is worth, I'm looking at Sather right now. It is inspired from Eiffel
(up to its name, referring to the Sather tower of Berkeley :) ), but has
derived away from it, and adopted many nice ideas like iterator methods,
closures, etc... that make it look a bit like Ruby. Actually, Sather looks
quite a bit like Ruby, with the main difference being that it is statistically
typed. I often find conventions used by Ruby that are used by Sather too,
although not always for the same use (for instance, Sather uses the ! character
at the end of some methods, but it uses it for iterators rather than for
destructive methods). Method names are often similar to those used in Ruby.
All in all Sather is quite an interesting language from a Ruby point of view.
Too bad that its community is non-existent (although the official compiler, GNU
Sather, is still reasonably supported, last update being in June of this year).

I'm not familiar with statistical typing. Does this mean that the
compiler guesses a variable's type based on a random sample of similar
variables from previous programs? :-)

LOL! Oops! I naturally meant *statically* typed (never do five things at the
same time!), although I must say I like the idea of statistical typing the way
you describe it ;) . I foresee nice derivatives like fashionable typing (a
variable gets the type the majority of variables get at a certain time), ghetto
typing (the variable gets the type of variables that look like it in similar
programs) or rebel typing (the variable gets a completely different and if
possible opposite type from similar variables in classes in the inheritance
chain of the variable's class ;) ).
And they said Intercal was difficult ;) .

Because it was never useable in practice. A very bad compiler for
practical use and no libraries. It was always nothing more then a
research project from one professor and his small group.

Beta isn't that bad, but I prefer the Smalltalk-OO,
http://www.daimi.au.dk/~beta/
Alpha sounds more like assembler to me. ;-)
I guess we really need to switch over to spy-related themes for naming
programming languages. :-)
