[Caml-list] ocamlbuild and pack
Hi List, I have the following problem. I have three files, each consisting of one line: a.ml: type t = float b.ml: type t = A.t c.ml: include B Now I want to put these modules into a pack, but I only want to export A and C, so I write a file project.mli: module A : sig type t end module C : sig type t = A.t end As I want to use ocamlbuild, I also create a file project.mlpack: A C Now, the command "ocamlbuild project.cmo" works fine, but I can't build a library from that: ocamlbuild project.cma Circular dependencies: "project.cmo" already seen in [ "b.cmo"; "project.cmo" ] There clearly aren't any circular dependencies, are there? Am I missing something? The problem goes away if I export B instead of C. So the troublemaker seems to be the include directive. I almost forgot: I am using ocaml 3.10.2 from godi.

[Caml-list] [ANN] mlpost 0.6
Hi List,
We have just released version 0.6 of mlpost, an ocaml library to
produce nice looking postscript figures with tex-typeset elements.
You can get it at:
http://mlpost.lri.fr/
Here is the changelog:
o - changes in behaviour, new features
* - incompatible changes in the interface
* "open Mlpost" is not added to input files any more -
users have to add by themselves
* the type Command.figure becomes Command.t
o inclusion of external images (png, jpg etc)
o transformations on boxes
o Box.{grid,gridl,gridi}: new options hpadding, vpadding, stroke, pen
o additional options for many functions
o corrections of some small bugs in box calculations
o A function in the API to scan a TeX file for the prelude
Have fun,
the authors of Mlpost

Is this the best way to > hide a module ? I don't know of a solution without changing your code. You could either remove your internal .mli files and put all the interfaces into algo.mli. Or you create a file signatures.mli which contains the relevant signatures. In pub1.mli, you could then write include Signatures.Pub1, and so on, and similarly for algo.mli.

I'd have thought the latter would be a harmless type annotation... My guess is that the problem here is not about scope but about quantifiers : the type of f is quantified universally by default but the annotation constrains the type of f to a fixed (yet unknown) type in the subsequent expression (in that sense, yes, the scope of f plays a crucial role). I think John Harrop is right and the scope of 'a is really the issue here. First of all, transforming "let ... in" into a top-level let makes the code work again: # let f (x : 'a) : 'a = x;; val f : 'a -> 'a = # f true;; - : bool = true # f 3;; - : int = 3 which suggests that the scope of type variables in annotations is a top-level let-binding. I think I have read about this somewhere, but I can't find the right page of the manual ... Also, the following code fails: # let f (x : 'a) : 'a = x in (f true, (3 : 'a));; Error: This expression has type int but an expression was expected of type bool Here it is clear that all annotations are talking about the same variable 'a. If 'a was existentially bound twice (once for the function definition, once for the constant 3), a type error would not occur. Johannes ___ Caml-list mailing list.

You can either use the mlpost-users list on mlpost's ocamlforge site -
it hasn't seen much use yet, but this shouldn't hold you off - or
simply send an email to one of the developers.
> I would like to draw variable size curly braces,
Unfortunately, this is trickier than one might think. TeX itself makes
use of some special characters in the font to do it. However, there
still are several possibilities.
The first is to simply scale the "{" character to the right size,
using either Picture.tex or Box.tex and the corresponding xscale /
yscale functions. However, it's difficult to get it right, it never
has quite the right proportions, and rarely looks good.
The second option is to obtain the intended size (using Box.height /
Box.width etc.), get a float value of this size using the
Concrete.float_of_num function and generate the curly brace using the
corresponding latex macro.
The third option would be to use the same trick as latex does
(aligning several characters of the font) in mlpost, but off the top
of my head I couldn't do it right now.
We really should put such a function in the interface ...
Johannes

The output of the ./configure script (at the beginning of the GODI output) prints if it uses the cairo backend (in the 0.7.x versions, Concrete is still part of the cairo backend; this will be better in 0.8). You need bitstring and the cairo-bindings for this, but the GODI package has the right dependencies. Johannes -- Johannes Kanig johannes.ka...@lri.fr ___ Caml-list mailing list.

[Caml-list] [ANN] release mlpost 0.8.0
Hello Caml-list, Mlpost 0.8 is finally out! You can get it at http://mlpost.lri.fr/ or at the ocamlforge. Notable changes are a few new modules, such as Tree_adv which delivers more powerful placement of trees, using overlays, or Real_plot, a nice alternative to Plot for float-valued functions. There also is a new system of contributions (contribs), and two contribs for the moment. The first, Mlpost_lablgtk, allows to easily include Mlpost figures into a GTK interface. The other one, Mlpost_dot, draws graphs using a placement as given by the dot(graphviz) tool. The Cairo backend is considered stable now and delivers mostly identical results as the Metapost backend. It supports PS, PDF , PNG and SVG output. A few minor bugs have been fixed, thanks to Julien Signoles, Stéphane Glondu and others. Finally, there are 4 incompatible changes, hopefully they do only affect a few people. See the CHANGES file for more details. Have fun and do not hesitate to submit bug reports, either by mail to the developers, or via the bug tracking system on the forge. If you want to follow the Mlpost development more closely, we are now using a public git repository at the INRIA forge: git clone git://scm.gforge.inria.fr/mlpost/mlpost.git The Mlpost developers -- Johannes Kanig johannes.ka...@lri.fr ___ Caml-list mailing list.
