I used to use nn, now I use tin which is fairly similar and still

It kinda worked for me but I had to change it a little:
os.system('for file in /tmp/*.tex; do pdflatex "$file"; done')
Maybe you're picking up other files in /tmp that are not .tex files?

No, the tmp folder only contains files, and your modification still
won't work for me.
By the way I have the same error if I do:
files2compile = os.listdir('./tmp/')
for f in files2compile:
os.system('pdflatex '+f)

I think your bug is in the lines you chose not to share with us. I
bet you've forgotten to close the last file you create, so that file
has changes that haven't been flushed out to the disk yet. Make sure
you call close() on each of the files when you're done writing them.

==============================================================================

From: Alan Harris-Reid
I have a web-page where each row in a grid has edit/delete buttons to
enable the user to maintain a selected record on another page. The
buttons are in the form of a link with href='/item_edit?id=123', but
this string appears in the URL and gives clues as to how to bypass the
correct sequence of events, and could be risky if they entered the URL
directly (especially when it comes to deleting records).
Is there another way of passing a record-id to a method
a) without it appearing in the URL?
b) without the user being able to fathom-out how to attach which id to
which URL?
As each link contains row-id, I guess there is nothing to stop someone
from getting the id from the page source-code. Is it safe to use the
above href method if I test for authorised credentials (user/password
stored as session variables, perhaps?) before performing the edit/delete
action?
I am currently using CherryPy 3.2, but I guess the theory could apply to
any HTTP framework or web app..
Any help would be appreciated.

You should *never* use a GET request to do actions like deleting
records. You already are aware of it being risky, so don't do this. You
should use GET for getting information, and POST for modifying information.
> Is there another way of passing a record-id to a method
> a) without it appearing in the URL?
Use a POST request. Note that the user still has to select something,
and that this information is send by the browser, and hence the user can
see this information (and maybe others), and repeat the action with, for
example, a Python program.
> b) without the user being able to fathom-out how to attach which id to
> which URL?
I am not sure what you want to prevent here. If you're afraid that user
A can delete things that belong user B, than "hiding" things or making
them "hard to guess" are not going to help much. If you have several
users, you must use some login procedure (and sessions).

Yes. But still make sure that session ids are not easy to guess, and
expire. And make very sure that session ids can't leak to others.
Moreover, each time you modify a database use POST. One could argue to
also use POST for logging out, otherwise another site might be able to
log your users out if they visit that site.

Well, if it's really ok for them to delete records programmatically even
if it's ok for them to delete through the web site. I'd probably
encrypt the post parameters if this was a concern.

That's fine so long as I can also treat the source as source, at need.
You may have just reinvented Smalltalk's Squeak editor (reputedly the
testbed for all of modern GUIs...).
Current editors suck because they can't see into the code and browse
it - unless it's so statically typed it's painful.
That's why I wrote this:

Your idea is certainly not new. Moreover, I've been using such an IDE
and implemented support for a (small) language in it:
Programs are hierarchical compositions of formulae satisfying
structural and extra-structural relationships. A program editor can
use knowledge of such relationships to detect and provide immediate
feedback about violations of them. The Synthesizer Generator is a
tool for creating such editors from language descriptions. An editor
designer specifies the desired relationships and the feedback to be
given when they are violated, as well as a user interface; from the
specification, the Synthesizer Generator creates a full-screen editor
for manipulating programs in the language.
http://portal.acm.org/citation.cfm?id=390010.808247
It might be a good start to read as much as possible on the Synthesizer
Generator if you want to write such an IDE for Python. I am sure you
could write such an IDE in the Synthesizer Generator, but I have no idea
if it's still available. And back when I used it (at university) one had
to pay for it, and most likely was closed source as well.

? I edit Python in MonoDevelop 2.2; and I can browse my file,
classes, etc... So I don't know what you mean by "can't see into the
code". It works pretty well.
Of course it can't tell that I've set x = {an integer}, as that only
happens at runtime.

You just said that your code browsing "works pretty well, except when
it doesn't".
Hence my blog entry. If your editor analyzed your code at runtime,
instead of just static analysis, then it could see that x = an
integer, or an object, no matter how dynamic your language.

So, '$Id: gmpy.c 237 2010-01-10 03:46:37Z casevh $' would be Revision

Then gmpy.version() isn't really intended to be a version per se,

Historically, gmpy really didn't have alpha/beta/rc versions and
gmpy.version() just had the version "number" and didn't indicate the
status. If I change it, I'd rather go to "1.1.1rc1" or "1.2.0a0" but
that might break some applications.

From: Raymond Hettinger
For those who are interested, the Sauce Labs team, http://saucelabs.com/about/team,
is hosting two free tutorial open space sessions at Pycon in Atlanta.
In the short session, people bringing their laptops should be able to
record a web session in their browser, convert the recorded activity
to a Python script, modify the script to accept a number of inputs ,
and replay the script locally on their laptops. Once you've learned
how to fully automate your own browser, submit the same script to the
Sauce Labs cloud to run the tests in parallel across multiple browsers
and operating systems, and view the results with instant video
playback.
The tutorials should be of interest to web developers wanting fast,
cross-browser testing and it should be of general interest to anyone
wanting to use Python to automate browser sessions.
The tutorials are being led by Jason Huggins, the creator of Selenium
(an open source web app testing tool http://seleniumhq.org/ ).
Several familiar names from the Python community will also be on-hand:
