pyncurses-list Mailing List for PyNcurses

Greetings,

I got the following problem when i try to run the form example in the 
example/ directory:

morpheus# python form_example.py
Traceback (most recent call last):
  File "form_example.py", line 2, in ?
    from ncurses.form import *
  File "/usr/local/lib/python2.3/site-packages/ncurses/form.py", line 
27, in ?
    from ncurses.panel import *
  File "/usr/local/lib/python2.3/site-packages/ncurses/panel.py", line 
23, in ?
    from ncurses.curses import *
  File "/usr/local/lib/python2.3/site-packages/ncurses/curses.py", line 
23, in ?
    from ncurses import _curses # import curses interface
ImportError: /usr/local/lib/python2.3/site-packages/ncurses/_curses.so: 
Undefined symbol "_nc_tracebits"


Im running Python 2.3 from a FreeBSD 5.2.1 system, and I installed both 
python and pynurses from the ports.

Any help would be greatly appriciated.

Best Regards,
Thomas Jacobsen

Dear *,

yesterday I downloaded the debianized version of pyncurses-0.3. Everytime
I tried "from ncurses import curses", I got an error saying "ImportError:
/usr/lib/python1.5/site-packages/ncurses/_curses.so: undefined symbol:
trace". After some research via "nm -D -g /usr/lib/libncurses.so", I found
out that the Debian version of libncurses.so does not contain the
debugging trace routines. This could also be the reason for an error I
saw on the mailinglist
(http://www.geocrawler.com/archives/3/2143/2000/11/0/4727576/).

After commenting out
  extern char *_nc_tracebits(void);
  extern char *_tracechar(const unsigned char);
  extern void trace(const unsigned int);
in "ncurses/_curses.i" and changing
  mcprint, has_key, _nc_tracebits, _tracechar, \
  trace, _nc_visbuf
to
  mcprint, has_key, _nc_visbuf
in "ncurses/curses.py" the examples seem to work fine (except for
menu_example.py which seems to have the same problems as mentioned by Tom
Newman in "http://www.geocrawler.com/archives/3/2143/2000/5/0/3689787/".)

Rebuilding the Debian-packet from source didn't work, because
"debian/rules" needed the missing files "compile.sh" and "install.sh". So
I had to re-debianize pyncurses. I submitted the patch to the tracker.

To Radovan: I don't want to "steal" your maintainership, I just don't want
to blame you for all the errors I possibly introduced.

share and enjoy, matthias

hi all,

is there any activity on the list?

I'm encountering nasty troubles trying to compile the package:

neither the distutils way nor the swig one will work on my box ;(
(see attachments)

Could any body point me to the correct link where i could find a
solution?

Thx

Hi all,

I would like to use pyNcurses to interface python with PostgresSQL.
I was trying the examples but  I see only very  rudimental examples,
the menu_example doesn't work for me and I  don't know how to use
colors.
I see this project is still in alpha release. Is it still active or it 
is dead?
Is there anyone on the list using pyNcurses for a real world project?
Someone has more sophisticated examples how to use pyNcurses?
I'm new to ncurses, I would like to know if  there is some documentation
about how to use pyNcurses.

Thank you very much for any help

Hello,

I've successfully used Pyncurses-package (.rpm) in my app with Mandrake
Linux 7.0.  But when I installed 7.2 of the same dist, Pyncurses stopped
working.  I compiled the .src.rpm, but no avail.  Here's the output:

-- 8< --
    from ncurses.panel import *
  File
"/var/tmp/pyncurses-buildroot/usr//lib/python1.5/site-packages/ncurses/panel.py",

Something is obviously missing but what could it be?


TIA,

jsh

        http://lemon.tky.hut.fi/linux/cplay/

        Supports both pyncurses and the old cursesmodule. I haven't
        done too much testing, but it seems ok.

Is the bug in ncurses or in pyncurses? (I've never used
either menu or panel, using cursesmodule-1.5b2 or the perl
Curses module. I create menus and text entry windows using
Curses::Widgets in perl.)

Harry and folks,

I got menu_example working. Here's the diff:

I had to change getch() to menu_window.getch() in the input
loop.

I had to add a refresh after the stdscr was created in
order to see it. Before I changed getch() to
menu_window.get(), the stdscr did get displayed (but the
menu window didn't).

KEY_DOWN and KEY_UP aren't recognized
(and they are when I'm using  cursesmodule-1.5b2). (I
haven't tried the HOME and END keys.)

This is a known bug when using both 'menu' and 'panel', I hope to get a
chance to look at it this weekend.

I forgot to mention: either I or one of the scripts removed
'keybound' and 'curses_version' from the
'# import some built-in functions
from _curses import...' 
statement in curses.py.

Harry,

Success!
Thanks for your help.

Here's what I did:

- removed the lines mentioning keybound and curses_version
from both _curses.i and ncurses_new.h (I had to use the
debian patch)
- ran make_c.sh
- ran setup.py build
- ran setup.py install
- ran the example scripts from inside their directory
(examples/)

example/menu_example.py gives me a full-screen box
containing, on the line above the bottom border:

Press space to select, arrow and Home/End to navigate

I.e., there are no choices printed. And the space, arrow,
Home and End keys do anything. But I haven't yet looked at
the script - maybe I can figure it out.

Try running curses_example.py from inside the 'examples/' directory, or if
you did not run `./setup.py install`  from inside the
'build/lib.linux2-ppc' directory. If you run it from the top directory it
will pick up the 'ncurses/' as module ncurses and will not be able to
import _curses.so because that is in 'build/lib.linux2-ppc/ncurses' (or
'/usr/lib/python15/site-packages/ncurses' if you ran
`./setup.py install`.

Here's the only reference to keybound in curses.h:

extern char *keybound (int, int);

and keybound does not appear in the list of function
prototypes in curses.h

When I do that, I no longer get the keybound error message,
but now I get this:

  File "examples/curses_example.py", line 2, in ?

They are slightly bigger than mine, but that is almost certainly the
result of being built for PPC which I am almost certain has larger
binaries. (PS Is the PPC as fast as they say? A friend of mine keeps
promising to put Linux on his Mac but keeps wimping out.)

Tom,

  Try removing _curses.i line 243, many functions in ncurses are really
macros, and macros do not get along with SWIG (at least not 1.1.5), for
whatever reason your version of ncurses may have keybound as a macro while
mine has it as a function (you could also look into curses.h, all the
definitions are commented in the prototype to show whether they are macros
or not.) Try building again with line 243 missing from _curses.i , tell mo
the result and we will work from there.

hi,

Thanks for creating this module, Harry.

I ran setup.py build and setup.py install.
I get this when I try any of the example scripts or even a
script that says nothing but 'import ncurses.curses':

Traceback (innermost last):
  File "curses_example.py", line 2, in ?
    from ncurses.curses import * # import the curses module
  File
"/usr/lib/python1.5/site-packages/ncurses/curses.py", line
23, in ?
    from ncurses import _curses # import curses interface
ImportError:
/usr/lib/python1.5/site-packages/ncurses/_curses.so:
undefined symbol: keybound

I then cleaned all the files made in the previous try and ran
make_c.sh. No change - I got the same error message.

linux 2.2.15pre3 on a power mac (linuxppc distro)
ncurses 5.0
python 1.5.2-7

I've used ncurses successfully using the python module cursesmodule.1.5b2
and using the perl module Curses.

Is keybound the first symbol in _curses.so? I'm wondering
if the problem has nothing to do with 'keybound', but
rather with importing _curses.so at all...

Here's the sizes of the .so files. Do these look right?

-rwxrwxr-x   1 root     root       219780 May  2 18:52 _curses.so*

-rwxrwxr-x   1 root     root        56810 May  2 18:52 _panel.so*

The two features I don't use, panels and colors, an you've asked about
both ;) There are color functions in there, but I have not tested them
(having no experience my self with ncurses) I will check these out (as
well as the panel problem.)

I will try to work up an example of this an put it on the list.

Hopefully there will be more examples as more people use the library,
right now there are only three of us on the list, but 167 people
downloaded  0.2, and 87 people have downloaded 0.3 in the last three days,
so I hope there are more users than that. I do almost all of my work in
the form module for clients with monochrome terminals, so I do not have
alot of experience with certain areas of ncurses, but if people will tell
me where they are having problems I will do my best to try to figure them
out.

How was the new installation procedure?

Hello,

I want to create an application that uses colors and buttons...

1. Is it possible to use colors with pyncurses? How?

2. How do i create "ok", "clear", "cancel" buttons that give
color feedback to the user? How do I tab between the buttons?

3. Can someone direct me to script examples of pyncurses or
ncurses.

Thanks alot!

pauld | p...@ch...

There is a new procedure for compiling the CVS version of PyNcurses.

First, you must install the Python Distutils available from one of the
following addresses:

http://www.python.org/sigs/distutils-sig/download/Distutils-0.8.1.tar.gz
ftp://pyncurses.sourceforge.net/pub/pyncurses/Distutils-0.8.1.tar.gz

These are easy to install, untar them and change to the Distutils-0.8.1
directory, then run the following commands:

=2E/setup build
su
=2E/setup install

To install PyNcurses run the following commands
=2E/make_c # generates C from SWIG
=2E/setup build
su
=2E/setup install
