ANN OCaml Batteries Included alpha 1

ANN OCaml Batteries Included alpha 1

[David Teller]

      Dear list,

 We're happy to inform you that the first alpha version of OCaml
Batteries Included has just been released. You may find the source on
the Forge [1], as well as the release notes [2],  and you can browse the
documentation online, including a detailed presentation of what OCaml
Batteries Included is all about [3].  A GODI package has also been
uploaded for OCaml 3.10 .

The list of features is a tad too long for detailing it here. Let's just
say that there are new or improved data structures, i/o, unicode ropes,
syntax extensions, primitives for invoking some of the tools of the
toolchain, etc.

It's alpha-level code, so use with caution, and not all the features we
have in mind have been implemented yet. On the other hand, any form of
feedback is greatly appreciated.

Have fun coding,

Very good work! I have a small suggestion: in the instructions on how to
start using the batteries, include a small complete example of a
HelloWorld project which uses batteries (and package it up in a .zip).
This will help people get started. The current instructions presuppose
that the user already has some source code, which is not necessarily the
case.

Best regards,

Andrej

Thanks for the feedback.
In the .tgz, there's actually a directory called examples, which is
supposed to serve that purpose. We should make it clearer, though.

Cheers,
 David

Hi,

I think Batteries Included is a great idea and have been looking forward to 
seeing how it turns out.  I've just installed it and have been playing around 
with it.  A quick question, how do you get batteries to work in the toplevel?  
I tried the usual:

  # #use "topfind";;
  # #require "batteries";;
  No such package: bin_prot.syntax - Required by `batteries.bin_prot.syntax'

But I get an error.  Attempts to "#require" batteries.bin_prot.syntax yield 
similar errors.

This is quite important to me.  I don't know what the general sentiment of the 
community is, but the toplevel is one of the major reasons I use OCaml.  In 
fact, for every Makefile I write, I write an equivalent toplevel init file.  
This ensures that any code I write in the toplevel, will compile with no 
changes and vice versa.  Even when making simple edits to compiled code, I 
will open up a toplevel, load the library/file and open the correct name 
space of where the edit will take place (automated with some elisp of 
course).  This allows me to test, in the toplevel, each little change I make.

Thanks in advance,

Peng

Top-level with compiled libraries, Was: ANN OCaml Batteries Included

Hello. On the subject of using toplevel: I would love to use toplevel
to test my code but I need a lot of compiled libraries (written in C)
- such as FFTW, Lacaml, etc. - and as far as I know, it is not
possible to use compiled code from toplevel. Or am I wrong? Also, some
of my code is quite computationally intensive, so in byte-code it runs
too slowly.

Ideally, I would like to have only the module I am working on in
byte-code, playing with it interactively. All the other (stable)
modules and all the libaries would be a compiled code and the
byte-code and compiled code would seemlessly call each other. Is that
feasible?

Yours,

Jan

Yes. There's no problem using bindings to C from the toplevel.

AFAIK this is not possible. You will have to use byte code for  
everything except your C code of course.

Re: [Caml-list] ANN OCaml Batteries Included alpha 1

[David Teller]

          Hi,

 It seems we forgot one dependency in the README: you need Bin-prot to
get Batteries to work. I must confess that we could have removed that
dependency for Alpha 1, as we don't use any feature of Bin-prot yet.

Cheers,
 David

It is certainly possible to use Lacaml (and presumably also FFTW) in
toplevels.  There shouldn't be any noticable performance penalty,
since almost all of the computation time is spent in external
libraries written in Fortran or C.

Markus

I run into this problem occasionally as well.  My solution has always been to 
make the test problem smaller.  Eg. I was writing a driving directions 
generator (like Mapquest).  Testing on the US road network was too slow so I 
used the state of New Hampshire.  The toplevel helps my development and 
testing.  Once things look good, then I run on the real stuff with compiled 
code.

Thanks for your help.  Installing Bin-prot has seemed to fix that error.  
Unfortunately, now I get a different one.  To give some context, I am trying 
to create an equivalent toplevel init.ml file that corresponds to the 
ocamlbuild _tags file. 

To build a project with Batteries all you need is "<*>: use_batteries" in the 
_tags file.  I don't really use ocamlbuild so I am assuming the _tags file 
plays a similar role to your normal Makefile.

My equivalent init.ml file which aims to start an ocamltoplevel in an 
environment where any code that compiles will run in the toplevel consists, 
so far of:

  #use "topfind"
  #require "batteries"

The new error is: Reference to undefined global `Ref'

I am not familiar with Ref.  It looks like it's a module in Batteries, so I'm 
not sure why it's throwing this error.  I tried to open Data.Mutable to see 
if perhaps things worked despite the warning, but it does not appear to be 
so.

Any ideas?  I've attached the complete output below for reference.


Thanks in advance,


Peng
