ah
<orbitz>
giv eit awhile, you'll hate Python
<orbitz>
god knows I do
<orbitz>
(slighlty joking. I don't mind python but after a decade I have found certain aspects of it bother me considerbaly)
<halfie>
Ocaml is not a problem I think. It is the whole idea of functional programming that is strange .. for years I have been using C and Python
<halfie>
so OCaml is a mind-bender of sorts
<orbitz>
Ocaml isn't too bad since you can be fairly imperative in it
<orbitz>
the main problem iwth Ocaml is the lack of a good distirbution IMO

orbitz: what do you mean by distribution?
<orbitz>
aavogt: For someone who comes from Python, what you get in the ocaml tar.gz from INRIA is severely aenemic
<orbitz>
People new to ocaml also don't care about GODI or Batteries or OASIS. They want to slam them some keyboard and make cool programs with the minimal amount of work to get the libraries to do that
<aavogt>
python is the exception with respect to standard library size
<orbitz>
Ruby too?
<aavogt>
I have not looked at ruby
<orbitz>
aavogt: Even C++'s stdlib has a superior string module IMO
<orbitz>
Heck, some might argue C's doe stoo
<orbitz>
the difference being it's really really freakin easy to write those functions in Ocaml, but a newb doesn't nkow that
<orbitz>
What comes standard in haskell is also pretty huge
<aavogt>
ghc is getting rid of libraries
<aavogt>
ex. opengl bindings are separate
<aavogt>
orbitz: if you consider what's in the spec though, haskell has less than the inria ocaml
<orbitz>
I find that hard to believe
<orbitz>
aavogt: default ocaml only has 1 integer type and it is 16 bits
<orbitz>
aavogt: this is just the haskell report, not necssiarlyw hat GHC will include. is this correct (GHC has so much more than Haskell defines)
<aavogt>
so what are we actually comparing here?
<orbitz>
I also don't think Ocaml is a committee language
<orbitz>
so it's hard to compare
<orbitz>
I would say Ocaml is closer to GHC than close to Haskell 98
<halfie>
join #mpd
<orbitz>
In terms of being a distirbution of a language rather htan teh definition
<orbitz>
But regardless of what haskell defines you sohuld get, in GHC you get a lot of stuff with the base download. In Ocaml you get less. And IMO I think this is a fact that keeps some people from seriously using Ocaml. They download it, realize that String module doesn't even have a split function, roll their eyes and go back to Python
<orbitz>
I'm exagerating of course but I think the problem still exists
enthymeme has quit [Quit: rcirc on GNU Emacs 23.1.1]
<halfie>
you bet it exists (going back to Python right now!) ;)
<aavogt>
this is because it's hard to learn something new to accomplish something you could already
<halfie>
yes, sadly the whole system which I am trying to extend is written in Ocaml .. So probably I will have to re-write the whole thing in Python
<halfie>
or learn OCaml ...
<orbitz>
halfie: I suggest you learn Ocaml. While it has the problem i just pointed out (in my opinion), Ocaml the language is absolutely fantastic
<orbitz>
halfie: I am moving a lot of my Python to Ocaml in my spare time
<halfie>
orbitz: I see. I will try my best to learn Ocaml ...
<orbitz>
the first 20 or so minutes is all about finances which you may be un interested in, but i beleive Minksy maeks a great argument for hcoosing Ocaml if you are concerned with the quality and realiableness of your software

hello : I've a small problem with Str ... can anybody have a look at this : http://pastebin.org/148083 ?
<munga>
the problem is that the string_match function never returns (ocaml 3.11)
<flux>
interesting
<flux>
seems like a (serious) bug, the regexp isn't anything exotic either
<flux>
my recommendation regardless of the issue: use Pcre instead
<flux>
it has perl regexps and it doesn't use ugly global state

flux thanks for the assessment I'll fill a bug on the bts
ikaros has joined #ocaml
<thelema>
well, the regex definitely diverges. Looks like flaw in the engine.
<flux>
maybe it's not state machine-based
<thelema>
almost certainly it's not - there's not nearly enough code
<thelema>
I think.
<flux>
heh, Str.string_match (Str.regexp "\\(.*\\)*z") "hello hello hello hello" 0;; takes a little time
<flux>
but if I add more characters, the time apparently doubles always
<flux>
so it's a complexity issue. possibly unfixable?
thrasibule has joined #ocaml

possibly.

In using .mli files can i seperate type annotation from function defintion in Ocaml? like how in Haskell i can do foo :: x -> y
<flux>
in ocaml you would put such type definitions in the mli-file, yes
<flux>
if you want to put the type definition to the .ml-file, you can use syntax like: let foo : x -> y = fun x -> ..
<orbitz>
cool, because i liek top level functions type annotated but let foo (x : int) (y : int) : int = .. is pretty ugly IMO
<orbitz>
flux: ah, is that common at all? seems almost uglier?
jsk-afk is now known as jsk
ssp2055 has joined #ocaml
<flux>
I use at times. it has the advantage of catching type errors earlier and the syntax is more close to the one in the mli-files.
<thelema>
if you want, you can do :
<thelema>
let f : int -> int -> bool = fun x y -> x = y + 3
<thelema>
but best is to annotate in the .mli

<Camarade_Tux>
you're trying to compile ocamlopt yourself?
<babalu>
no i've installed the mingw port of ocaml and now i'm trying to use ocamlopt.exe to compile my program
<Camarade_Tux>
ok, you have a file named "*ws2_32*" somewhere?
<Camarade_Tux>
(not the .dll, on your mingw system)

<Camarade_Tux>
also, quick, dirty work-around: copy libws2_32.a to libws2_32, that's really ugly but I'm curious if it fixes the problem and if there are others
<babalu>
sorry it's in lib\
<babalu>
Camarade_Tux, it still cannot find it even after this
ulfdoz has joined #ocaml

ah!
<Camarade_Tux>
remmeber, and I had that problem two days ago =)
<Camarade_Tux>
export OCAMLLIB=/c/mingw/lib
<Camarade_Tux>
and try again
<babalu>
:D
<Camarade_Tux>
(and remove that ugly copy I told you to do ;-) )
<babalu>
Camarade_Tux, i'm working on windows right now so will this syntax work?
<Camarade_Tux>
you're in msys?
<babalu>
in what? yes i'm using the windows console
<Camarade_Tux>
I mean: only cmd.exe or in msys?
<babalu>
cmd.exe
<Camarade_Tux>
you haven't installed msys at all?
<babalu>
what is that?
<Camarade_Tux>
it's a kind of minimal posix system (minimal, ugly, often annoying)
<babalu>
i've added c:\mingw\lib to the OCAMLLIB environment variable, but now i get: >> Fatal error: cannot open pervasives.cmi Fatal error: exception Misc.Fatal_error
<Camarade_Tux>
where have you installed the ocaml files?
<babalu>
in C:\Program Files\Objective CaML

rename that folder to something without space, it always causes problems
<Camarade_Tux>
actually, move it outside of Program\ Files for now, maybe c:\mingw\ocaml
<babalu>
damn vista and authorization issues
<Camarade_Tux>
I said something wrong, OCAMLLIB shouldn't point to C:\mgw\lib (but if it works), it should be set to C:\mingw\ocaml\lib, but we'll see how it goes
<babalu>
Camarade_Tux, i reinstalled ocaml in C:\mingw\ocaml but i still have the same error
<Camarade_Tux>
babalu: ok, got it (I started a windows virtual machine to test): you should only need to set OCAMLLIB to c:\mingw\lib
<Camarade_Tux>
on the other hand, I have ocaml directly in the same tree as mingw
<Camarade_Tux>
meaning ocaml.exe is in c:\mingw\bin
<babalu>
hm ok; so what should i do?
<Camarade_Tux>
you need the PATH environment variable to contain C:\mingw\bin and OCAMLLIB to be the location you have pervasives.cmi in
ulfdoz has quit [Ping timeout: 246 seconds]
<babalu>
Camarade_Tux, OCAMLLIB does contain c:\mingw\ocaml\lib and there is pervasives.cmi in this folder
<babalu>
and the path environment variable also contains mingw\bin (i needed to add it for the program 'as')
<Camarade_Tux>
OCAMLLIB is only c:\mingw\ocaml\lib or is there another path separated with a ';' or ':'?
<babalu>
well i also put c:\mingw\lib, separated with a ';' C:\MinGW\ocaml\lib;C:\MinGW\lib
<Camarade_Tux>
I'm not sure ocamlopt will try to split that variable so try with _only_ C:\mingw\ocaml\lib
<babalu>
but then i got the libws2_32 error message, should i copy the content of mingw\lib into mingw\ocaml\lib?
<Camarade_Tux>
you tried with only c:\mingw\ocaml\lib and are still getting it?
