GBlearn 2 and lush2.0.1

Hello list

This is my first email to the list, and Im sorry to come with problems
for you guys :)

I am interested in using the gblearn framework to build OCR recognition
software in bad conditions (think CAPTCHA) for a research I am
conducting, and I have a small lisp background, so lush seemed like a
great asset.

But the code for lenet and gblearn itself does not work with the latest
lush version. Comparing the 2.0.1 code with the code at the CVS, which I
suspect is from lush 1.0, I have managed to track the problem down to
the load-matrix function, and I just used this line on the index.c file
to solve the immediate problem :

   /* little fix to resolve the load-matrix not found error . */
   dx_define("load-matrix", xload_array);
   /* END FIX */

The problem is, the more I investigated the diffs between the indexes
from the different versions, the more it became clear that there were
great differences between the version regarding matrixes (or arrays as
they are now called in the index.c).

I am writing to ask wiser people as to what should I do about it. Use
the old version? Export the names as old ones? Try to fix the code of
gblearn (Im inclined to do this)?

Thanks for the attention.

configure --without-readline


I just tried building lush without readline support. It looks like that is 
not possible anymore, not sure it ever was. Anyways, this turns out to be 
another road block for OS X users.

Any volunteers out there who would help with supporting '--without-readline'
builds?

ANN: Lush 2.0 released

All,

Lush 2.0 is finally out and available as source at
http://sourceforge.net/projects/lush/files/lush2/lush-2.0.tar.gz

There are no major new features since beta2 but a number of bugs
have been fixed. Thanks to all who reported bugs, in particular to
Fabian.

For the future I am planning to release more frequently and target
more moderate goals for each release. For Lush 2.1 I plan to further
improve the gnuplot interface and to make Lush work on OS X 10.6.

Cheers,
Ralf

canonical reference/citation for LUSH

Sorry if I am repeating myself (didn't find email, so I could have asked
that before):

what would be the canonical reference you would like people to use for
referencing lush?

bug tracker


On a related note, I disabled the Bug Tracker on the lush project page.
I had wanted to do this for a while since nobody seems to look at it
and tons of spam had been posted to it. As an alternative there is Trac
where people can create tickets for defects or enhancement requests.
Trac is accessible from lush's SF project page.

finalizing the Lush 2.0 release

Hi all,

I have been fixing a number of lush 2.0 bugs over the last
couple of days and want to do the lush 2.0 release soon.

If any of you have access to other platforms than a current
Ubuntu linux I would appreciate it if you would try to build
it on your system (I know there are problems with OS X 10.6).
Here is the tarball:
http://sourceforge.net/projects/lush/files/lush2/lush-2.0.tar.gz/download

If I don't hear from anyone about build problems or otherwise
then I will announce the release in two days or so.

Cheers,
Ralf

problem running a demo

Hello,
I just downloaded from sf and installed lush on /usr/local on my 64 bit
AMD ubuntu 9.10. I tried creating a file spline.lisp with the listing
from the web site. I am getting :

...
...
Generating C for var_gsl_qrng_sobol ...
gcc -DHAVE_CONFIG_H   -std=c99 -DNO_DEBUG -Wall -O3 -march=nocona
-pthread -I/usr/local/share/lush2/include
-c /home/osman/.lush2/packages/gsl/C/aux_globalvar.c
-o /home/osman/.lush2/packages/gsl/C/x86_64-unknown-linux-gnu/aux_globalvar.o
dldbfd: x86_64 relocation overflow (gsl_rng_default_seed)
  This happens when accessing data variables
  located in a shared object loaded via dlopen
  Instead of
     extern int remotevar;
     if (remotevar = 15) ....
  You can do:
     extern int remotevar;
     static int* volatile premotevar = &remotevar
     if (*premotevar = 15) ....

*** module-load : dld/bfd error
*** Overflow during relocation :
"/home/osman/.lush2/packages/gsl/C/x86_64-unknown-linux-gnu/au ... 
Debug toplevel [y/N] ?n

Anything I can do?
Thanks in advance

String functions


I have been working on revising the string functions
lately. Names like 'left', 'right', and 'index', have
been bugging me since I started using lush. Here is a
summary of the current state:

? ^Astr-
Search Results for: str-
   1. (str-cat  <s1> ... <sn>)
   2. (str-mid  <s> <n> [<l>])
   3. (str-right  <s> <n>)
   4. (str-left  <s> <n>)
   5. (str-insert <s> <n> <s1>)
   6. (str-subst <s> <s1> <s2>)
   7. (str-del <s> <n> <l>)
   8. (str-join <unsep> <ss>)
   9. (str-split <s> <sep>)
  10. (str-startswith <s> <prefix>)
  11. (str-endswith <s> <suffix>)
  12. (str-find <s> <r> [<n>])
  13. (str-val <s>)
  14. (str-strip <s>)
  15. (str-stripl <s>)
  16. (str-stripr <s>)
  17. (declare (-str-) <var1>...<varN>)
choice>

There are also two new functions 'string-to-vector'
and 'vector-to-string', which do the obvious.
