hey that does sound neat. What are you using to model teh butterflies? :)
<Smerdyakov>
A room full of butterflies

What else?
<hcarty>
Jeff_123: It's all satellite data, so no physical modeling at this point

<jeffwheeler>
I'm having trouble getting imports to work just right in Debian (Sid) -- specifically, I am unable to ``open Pxp_yacc'' (I have the package installed), with an error of an unbound module.
<jeffwheeler>
Googling seems to suggest that I would need to compile an mli file or something, but I'm new to this and am unsure if that is correct... or even how to go about doing that.
<bluestorm_>
you have to give the related .cmo/.cma file to the compiler
<bluestorm_>
do you know where is pxp located in you /usr/lib/ocaml ?
<orbitz>
hwo does the interpreter find stdlib ones? can you give it a directory and just say "find modules here"?
<bluestorm_>
hm
<bluestorm_>
orbitz: yes, -I
<bluestorm_>
but you still have to give modules name manually, iirc
<bluestorm_>
hm
<orbitz>
you still have to specifythe moudles to the itnerprter though
<bluestorm_>
seems pxp on debian use ocamlfind
<orbitz>
doe sit have the quivalent of a CLASPATH?
<bluestorm_>
jeffwheeler:
<orbitz>
bluestorm_: can i paramaterize a function around any tp eof Set?
<bluestorm_>
try (if your source is foo.ml) : ocamlfind ocamlc -package pxp -linkpkg foo.ml -o foo
<bluestorm_>
hm
<jeffwheeler>
oh, sorry, was looking at the other screen Googling some more
<orbitz>
or i guess more generic a question, can i paramaterize a function around aa functor
<bluestorm_>
i'm not fluent with functors
<bluestorm_>
but i'm afraid you can't
<orbitz>
that is the fear i have as well
<jeffwheeler>
thanks a bunch bluestorm_, I'll try that
<bluestorm_>
what you could do is to write a functor yourself
<bluestorm_>
giving that function
<bluestorm_>
and relying on the functor signature
<orbitz>
i cold pas Fucntor.foo to every functiont aht want sto call foo
<orbitz>
but that seems poor
<orbitz>
it would be nice if som ehow i could just do Set.foo and it coudl work across sets
<bluestorm_>
create a functor that would generate the your foo from the Set.Make output given
<jeffwheeler>
bluestorm_: works great; thank you
<bluestorm_>
(or even generate an enhanced Set from a single OrderedType)
lde has quit [Read error: 104 (Connection reset by peer)]
<bluestorm_>
orbitz: i agree having to use functors yourself may seem a bit heavy, but otherwise it's a quite nice solution
<orbitz>
bluestorm_: what is a solution to set that doens't use functors?
<bluestorm_>
hm ?
<bluestorm_>
are you asking for a non-functorial set-like library ?
<orbitz>
is there a version of Set that is like a Queue that does nto use a functor?
<bluestorm_>
i know there is some, but not in StdLib
<orbitz>
well the upside to osethign liek Queue is i don't care what type it holds
<bluestorm_>
ExtLib may have that
<orbitz>
the downside is it's mutating all around which i do not like
<bluestorm_>
orbitz: why are you so unwilling to use a functor yourself ?
<orbitz>
i was just thinking of if there was a non functo rway
<bluestorm_>
if Set is the datastructure you really need, i think you should try to use it instead of lesser equivalents
<bluestorm_>
hm
<orbitz>
bluestorm_: what would a functiont aht takes set and turns it to a list look like in this case?
<bluestorm_>
hm
<bluestorm_>
there are two possibilites
<bluestorm_>
you're only interested in a particular OrderedType case (for example ints), and thus you create an adequate Set yoursef (for example IntSet), and have a function to_list : IntSet.elt -> int set
<orbitz>
right, but what if i'm interested in turning a set of 'a to 'a list?
<bluestorm_>
orelse you want genericity, and you create a functor that takes an OrderedType as input, and produce an EnhancedSet back, with every function of Set, plus a to_list function
<bluestorm_>
to what i understand of functors, "set of 'a" does not make sense
<bluestorm_>
you only have YourSet.elt
<bluestorm_>
where YourSet is a module you created
<bluestorm_>
let me throw you some code
<orbitz>
bluestorm_: that woud work but i'm unsure it truly solves the problem, as I still need to know the name of the new module in order to call to_list
<bluestorm_>
hm orbitz
<bluestorm_>
do you know of the "elements" function ?
<bluestorm_>
val elements : t -> elt list
<orbitz>
right, but to list is just an example, what i'm really after is a way to perform owrk on a set withotu so much carring about the type
<orbitz>
perhaps my end goal is mistaken and it simply isn't a situation correctlyw ritten ocaml should come across
<hcarty>
Yes, pastebin.com seems to be broken here as well
<bluestorm_>
i use pastebin.be
<bluestorm_>
because it does OCaml
<bluestorm_>
orbitz: hm
<bluestorm_>
printf's typing is kinda obscure
<bluestorm_>
you can read the doc if you really want to know about it
<bluestorm_>
but it's not necessary
<bluestorm_>
for 99% of uses, it suffices to think that you have to type printf/scanf *with* the associated format string
<bluestorm_>
e.g. don't type (Printf.printf), type (Printf.printf "%s : %d\n")
<bluestorm_>
string -> int -> unit, it's easy
<orbitz>
maybe i'll atke al ook at it later then
<orbitz>
is this absically how it is allowe for an unknown number of arguments?
<bluestorm_>
yes
<bluestorm_>
there's some magic around here
<bluestorm_>
(or at least it's what you think when you don't know this stuff deeply enough, like me)
<munga_>
ok can anyone tell me why this example fails to compile with ocamlbuild ? http://pastebin.be/7655
<orbitz>
what's the error?
<orbitz>
can i export a record form a module or do i have to us ea create function?
<munga_>
I just figure it out ... I was calling camlp4 in the wrong way ... camlp4o instead of camlp4of !
Smerdy has joined #ocaml
<bluestorm_>
orbitz: you can
<bluestorm_>
you have to put the record in the module signature
<bluestorm_>
(the whole declaration)
kelaouchi has joined #ocaml
jedai has joined #ocaml

I'm compiling a simple program with ocamlbuild that uses camlp4 to write a parser. The compilation goes thought, but ocamlbuild fails to link camlp4lib.cma and therefore I get
<munga_>
Error while linking dnf.cmo: Reference to undefined global `Camlp4'
<munga_>
how can I convince ocamlbuild to link everything with camlp4lib.cma ?
<munga_>
of course it works if I do it by hand
<munga_>
shall I write a plugin fot this purpose ?
<bluestorm_>
-I +camlp4
<bluestorm_>
or -I camlp4 maybe
<bluestorm_>
hmm
<bluestorm_>
it's ocamlbuild
<bluestorm_>
don't know if you have to say something specific about not-in-the-usual-directory .cma, then
<bluestorm_>
munga_:
<bluestorm_>
« You may need to add options such as -cflags -I,/usr/local/lib/ocaml/ and -lflags -I,/usr/local/lib/ocaml/ if the libraries you wish to link with are not in OCaml's default search path. »
<munga_>
Do you have any idea how I can add these flags in my _tags ?
<hcarty>
orbitz: You can mess with camlp4 to get .[] .() .{} etc to do different things. They are all defined in the OCaml sources as sugar for the matching *.get functions
<orbitz>
that's ok, i was mostly curious as to how it works. at first iw as thinking string migh tbe a class but . is not the oeprator to calla metho don a class so that led me here
<munga_>
no ... doesn't work . the manual is kinda obscure ...
<bluestorm_>
seems you have to write a plugin
<bluestorm_>
to define your self tags
<orbitz>
when definign a class you do blah = object(self), is teh self necesary? I ge tan unsued variable warning form the compielr so I mad eit object(_). what is the self for?
<bluestorm_>
the self is for referring to the object
<bluestorm_>
kinda like "this" in some languages
<bluestorm_>
you can omit it if you have no use for it
<bluestorm_>
= object ...
<orbitz>
can one create anonymous classes?
<bluestorm_>
you create anonymous objects
<bluestorm_>
"class" are named objects schemes (don't know if it's the correct wording though)

what does it do there?

It lets you type (foo ~-1) rather than (foo (-1))

If that makes any sense... it's an associativity thing, but I don't remember the proper name. Unary operator perhaps?
