Hello,

I need to use an interval tree.

Biocaml has one, batteries have imap/iset, nice!

However, I have intervals of reals, not integers. :(

I want to build the tree (once), then query it with a real number
(many times) like in: which intervals contain the query real number?

Should I convert my floats to ints (by sorting them then ranking) before
inserting them into some existing interval tree for integers?
I am not so concerned about the pre-processing time.

Should I write from scratch?

Thanks for any suggestion,
F.

OCaml/MinGW

GCC shipped with (current) MingW no longer recognizes -mno-cygwin
argument, my oline searches for a workaround were fruitless, but
turns out there is one, one can create a self specs file and
make gcc (the driver) strip -mno-cygwin from cc1 invokation. This
can be done by putting a file named "specs" into a directory listed
under "install:" in the output of `gcc -print-search-dirs' containing
following line:
*cc1: %<mno-cygwin

Hope that would save someone the trouble of making things run.

[ANNOUNCE] llpp v10

Hello,

New version of llpp is now available (tagged v10) at
http://repo.or.cz/w/llpp.git 

Blurb:

llpp a graphical PDF viewer which aims to superficially resemble
less(1)

Changes (relative to v7, last version being announced here):

* MuPDF grown itslef XPS and CBZ support
* Margin trimming
* Multi column mode
* Probably more, since:

llpp$ git diff --stat v7..v10 | tail -1
 11 files changed, 5206 insertions(+), 2514 deletions(-)

sys command

Hello,

Does anyone know how I can launch a batch file from Ocaml without pop up 
windows.

Thanks

Fady

syntactic detail

Hi,

Ocaml allows me to add '_' at the end of a floating point literal, e.g.:

	1._

What can be a purpose for that?

In case of long or Long integers, optional adding of '_' between the
integer and 'l' or 'L' make sense ('l' is hard to discriminate from '1'
for many fonts). But in case of floats, I am not sure.

llpp video

Here's a video[1] that shows how to build and use llpp[2]. It drags,
with the building fetching part, till ~3:35, but, hopefuly, gets up to
speed after that.

Compiling Cryptokit on Windows

Hi list,

There has been some discussion during the last few months were some 
argued that there was not enough Windows users to test libraries. Well 
it happens that I need to compile Cryptokit for Windows. Here are my 
first results, which failed miserably. I'm using OCaml 3.12.

1) With Cryptokit 1.5.

INSTALL.txt states that I need findlib. I installed OCaml from:
	http://protz.github.com/ocaml-installer/
And it seems that ocamlfind is not installed by this tool. After more 
search I read here:
	http://www.camlcity.org/archive/programming/findlib.html
that "Volunteers are still wanted who port findlib to Windows and 
Macintosh."

So I guess that every OASIS project needs findlib, but findlib does not 
work on Windows, so all OASIS projects will not be usable on Windows? I 
thought on the contrary that OASIS was a step towards unification?

I tried anyway without findlib, running:
	ocaml setup.ml -configure
I get this error: "'c:\Program' n'est pas reconnu en tant que commande 
interne" (i.e. "unrecognized internal command"). The command which is 
supposed to be run is:
	c:\Program Files\OCaml\bin\ocamlc.opt.EXE -config > somefile.txt
It just misses quotes, which seems kind of silly.

2) With Cryptokit 1.3.

So I gave up and tried an older version whose INSTALL file explains how 
to install on Windows.

I checked variables in Makefile.win and ran:
	make -f Makefile.win
Now the error I get is that gcc cannot find "C:\Program 
Files\OCaml\lib/ocamlrun.a", which actually does not exist, so this is 
not a surprise. This file "ocamlrun.a" does not exist either on my 
Debian computer, so I'm a little surprised here.

I think I'll try cross-compiling now, or maybe editing "setup.ml" to put 
quotes around the command.

Cheers,

--

TFPIE: Trends in Functional Programming in Education 2012

CALL FOR PAPERS/PRESENTATIONS TFPIE 2012
International Workshop on Trends in Functional Programming in Education 2012
June 11 2012
University of St Andrews, Scotland
http://www.cs.ru.nl/P.Achten/TFPIE_2012/TFPIE_2012_home.html

The first International Workshop on Trends in Functional Programming in Education, TFPIE 2012, will be
co-located with TFP 2012 at the University of St Andrews in Scotland. The goal of TFPIE is to gather
researchers, professors, teachers, and all professionals that use or are interested in the use of
functional programming in education. TFPIE aims to be a venue where novel ideas, classroom-tested
ideas, and work in progress on the use of functional programming in education are discussed. The one-day
workshop will foster a spirit of open discussion by having a review process for publication after the workshop.

The program chairs of TFPIE 2012 will screen submissions to ensure that all presentations are within scope
and are of interest to participants. Potential presenters are invited to submit an extended abstract
(4-6 pages) or an article (up to 16 pages). The authors of all accepted presentations will have their
preprints and their slides made available on the workshop's website/wiki. Any visitors to the TFPIE 2012
website/wiki will be able to add comments. This includes presenters who may respond to comments and
questions as well as provide pointers to improvements and follow-up work. After the workshop, the
program committee will review, using prevailing academic standards, the articles accepted for
presentation to select the best for publication in Electronic Proceedings in Theoretical Comp
 uter Science (EPTCS). Articles rejected for presentation and all extended abstracts will not be formally
reviewed by the PC.

TOPICS OF INTEREST

TFPIE 2012 welcomes submissions describing practical techniques used in the classroom, tools used
and/or developed, and any creative use of functional programming (FP) to aid education in or outside
Computer Science. Topics of interest include, but are not limited to:

FP and beginning CS students
FP in Artificial Intelligence
FP in Robotics
FP and Music
Advanced FP for undergraduates
FP in graduate education
Engaging students in research using FP
FP in Programming Languages
FP in the high school curriculum
FP as a stepping stone to other CS topics
FP and Philosophy

If you are not sure if your work is appropriate for TFPIE 2012, please contact the PC chairs by e-mail
