Python output printed too late

[Antti Kaihola]

When compiling the attached .py source, the output from one of the Python "print" statements doesn't appear below the statement. It's printed just before the output of the next statement instead.

I'm on Ubuntu Hardy and running the current trunk of pyreport:
revision-id: <email address hidden>
date: 2008-01-28 10:52:23 +0100
build-date: 2008-09-18 16:18:30 +0300
revno: 26
branch-nick: pyreport

This is (sort of) fixed under revno 35 running under python 2.6. Some weirdness was going on with the parsing code that behaves differently between the versions. Unfortunately, now all code blocks are preceded by a blank line, and code output follows the subsequent rst comment. This should be a pretty easy fix, I'm having a go at it now.

Hi,

I have the same problem. The output arrive too late.
I'm on ubuntu hardy and python 2.5.2. How can i do ?

thanks in advance.

[Kamel (kamel-maths)]

It seems that the problem occurs whith comments as #! .
Without comments, it works pefectly.
Is there a solution with my configuration ?

[Gael Varoquaux (gael-varoquaux)]

I believe that I fixed this problem in revision 39 of the development version of pyreport. There should be a new release, but I'd love feedback on this issue.

And sorry for the slow answer, I have been struggling with so many things to do.

[Kamel (kamel-maths)]

You don't have to be sorry for the slow answer. I love your work and I accept to wait for that.

I don't know what is the revision 39. The version of pyreport I use is the 0.3.4a that I found in your homepage. A few minutes ago, I saw that there exists a younger version, the 0.3.4b at http://pypi.python.org/simple/pyreport/.
I have downloaded it to see if the problem still occurs with this version, but after extract it, I don't know how to install it.

Thanks.

You should be able to instal it using 'python setup.py install', in the
directory of the tarball. The way to install it is excatly the same way
as version 0.3.4a.

Hope this helps,

Sorry, I am completely lost.

I tried to install the version 0.3.4b but the version recognized by my computer still was the 0.3.4a. So I delete some files manually (I know it is not good but I was angry). Then I begin again to install the 0.3.4b. I have the impression all is ok but when I call pyreport I have : bash : pyreport : commande introuvable.

This is the message I have after 'python setup.py install' :
/usr/lib/python2.5/distutils/dist.py:263: UserWarning: Unknown distribution option: 'summary'
  warnings.warn(msg)

Removing /usr/lib/python2.5/site-packages/pyreport-0.3.4b.egg-info
Writing /usr/lib/python2.5/site-packages/pyreport-0.3.4b.egg-info

But after nothing ...
Thanks for your help.

OK, your previous problem may be due to pyreport being installed via
'easy_install', and thus overriding the standard install. Can you try
install pyreport via easy_install, by typing the following command:

easy_install pyreport

Tell me if this works.

Thank you for your patience.

The message after 'easy_install pyreport' :

Then the message when I call pyreport :

    raise ImportError("Entry point %r not found" % ((group,name),))

Hey Kamel,

This might very well be due to an error on my side. I just uploaded a
version 0.3.4c, can you try easy_install again?

Thanks,

Gaël

[Kamel (kamel-maths)]

I've just tried 'easy_install' but this still installs 0.3.4b and not 0.3.4c :

kamel@kamel-desktop:~$ sudo easy_install pyreport

Ha, yes, you need to give the '-U' flag to easy_install:

easy_install -U pyreport

Yes, it works and no more problem of too late output. Thanks a lot for that.

I have another question (less important) about pyreport but I don't know if it is the right place to ask.
It is about the first line #!/usr/bin/env python of a script. On my computer with pyreport it is interpreted as a comment of the report (rst line ?) and not as a python comment. So I don't obtain the same result as your examples of your homepage. Is it normal ?

It looks like a bug. I'll try to work on it later in the week. Right now
I have a few deadlines to work on.
