How to run a setup command with 'pip install'?
Hello, I have a trouble installing the DMSL package with pip. The package doesn't have *.c files, which must be produced with Cython by 'pyhton setup.py build_ext' command. How do I run it with 'pip install'? Please see http://stackoverflow.com/questions/7189336/ for details. Regards, Andrei -- http://mail.python.org/mailman/listinfo/python-list

Detect if specific Python.app instance is already running
Hello,
I am experimenting with OS X apps written in Python and need to detect if there
is already an instance of Python.app running with certain script. My script
modifies CFBundleName on-the-fly from "Python" to "MyApp" to change the app
title in the menubar. If I start another instance and check CFBundleName of the
running apps, it will only tell me the original value, i.e. "Python":
for app in NSWorkspace.sharedWorkspace().runningApplications():
bundle = NSBundle.bundleWithURL_(app.bundleURL())
name = bundle.infoDictionary().get('CFBundleName')
if name in ('Python', 'MyApp'):
print name # => prints Python
So I need to find a way to mark a Python.app instance that runs MyApp script to
be able to abort launching duplicate instances. Is there such way?
Thanks,
Andrei

Re: Detect if specific Python.app instance is already running
Alright, I have had some development in http://stackoverflow.com/questions/30694560/detect-if-specific-python-app-instance-is-already-running and can prevent running multiple instances of the same app/script (by lockf), but I still need to identify which Python.app instance is running certain script. I guess it's more Cocoa-related question but I hope someone had same problem with tkinter etc. Andrei -- https://mail.python.org/mailman/listinfo/python-list

The problem is a bit tricky as I see it. Multiple instances of Python.app needs to be run since it may run different tkinter apps etc. What I need is rather simple: 1. start app, mark the instance with tkinter app name 2. start another one, detect that the same instance is already running and identify it 3. focus on the first instance, close the second one I have solved it with a lock file and a pid file (I guess I could use just one file for both jobs, but didn't have time to test it yet). I believe it could be done without files, i.e. by setting some public attributes on app instances. I could probably also use OS X key storage for this but it gets too similar to the file approach and I am not sure if it's any better. I may be wrong in my thinking. If so, just let me know :) Thanks, Andrei -- https://mail.python.org/mailman/listinfo/python-list
Re: Looking for a python IDE
> I am looking for a good IDE for Python. Commercial or Open Software. > If possible with visual GUI designer. > For the moment I am considering Komodo. There is no Python IDE that has a fully-integraded approach like Delphi or VS with all bells and whistles. Tools tend to be somewhat separate and can be combined at will, using any editor you like with any GUI designer you like. Boa constructor is an attempt at buildings something like Delphi, but it's quirky and has an unclear maintenance status. Some of the big names in Python IDEs are Spe, Eric, Idle, PythonWin and WingIDE. GUI designers you can use are wxGlade (for wxPython), Glade (for PyGTK) and QtDesigner (for Qt). Spe + wxGlade and Eric + QtDesigner are natural fits. It's really a jungle out there - your personal taste and toolkit preferences will have to determine your choice. If I like wxGlade, it won't help you if you want to build Qt apps, Eric doesn't work if you run Windows, etc. Yours, Andrei -- http://mail.python.org/mailman/listinfo/python-list
Python 2.7 importing pyc files without py files
Hi, I encountered a strange issue. I have an application which uses extensively python 2.7.6 (CPython). The issue that I see is the following: If there are only pyc files, the loading time of the application is much more than if I have pyc and py files. It is behind with 2 minutes more than if it had py files Do you have any idea why this is happening ? Maybe is because, python tries to search the py file in all the paths and this search is exhaustive ? This is the best guess I could figure it out but I'm not sure. Also, if this is the scenario, there is a way I can stop this, to not search for the py files ? is there an api ? or a compiling flag I should set ? -- https://mail.python.org/mailman/listinfo/python-list

Which Python Framework for REST API and Facebook Wrapper?
I will be designing a REST based API for a cross-platform back end that will serve both desktop Facebook users as well as mobile users. It will handle operations such as user creation, retrieval of user and other data, payment verification and in the case of the desktop side, handle the html/css template customization. The database back end is MySQL and I do need a cache system. Currently we were using Codeigniter (PHP) for our codebase but as CI seems on the way out, I do not wish to start a new project based on it. I was looking at Laravel for PHP, but, Python is very attractive to me as a language and since the introduction of WSGI, I am confident it can make a difference in performance and code maintainability over PHP while being able to plug in to our dedicated server infrastructure. Since I am not experienced with Python frameworks (though learning curve is not much of an issue for me) I look to the community to understand which Python framework can rival or surpass Codeigniter in terms of performance in heavy traffic backend solutions (over 1M requests per day, with up to 100 req/sec at peak). I really want to make the switch from PHP to Python as I believe that Python can solve more problems with less code and faster execution time, not to mention freedom from brackets and semicolons. -- https://mail.python.org/mailman/listinfo/python-list
Get EXE (made with py2exe) path directory name
I need to get absolute path name of a file that's in the same dir as the exe, however the Current Working Directory is changed to somthing else. I turn my script into an executable with py2exe, then I create a shortcut to the EXE on the desktop. I change the "Start In" variable of the shortcut "C:\somthing_else", so now the currect working directory of the executable is not the same as the directory where the EXE is located. I need to load a file that's in the same directory as the EXE, so I do the following: dir = os.path.dirname(sys.argv[0]) filepath = os.path.join(dir, 'server.pkey') however it doesn't seem to work.

Information manager/organizer with tags question.
Hello, I would like to write an information manager/organizer type of app but first I'd like to ask if there is something like that already existing. I asked on yahoo questions but did not get a response. I also searched freshmeat but even though they have plenty of projects that are tangentially related, I was unable to find anything close enough. What I'm thinking about is this: a database with an interface that stores records by tags and allows filtering and sorting by these tags. When I enter a new record, I enter a title and any number of tags. Interface would have a filter by: pull down menu separated in two sections, favorite tags and recent tags. To the right of that would be a button to add another filter, which would create a new pull down menu to filter current results further. Then there would be a search field where you'd type in a word and it would show a list of all matching tags; then you would click on one of the tags to add it to last filter menu's 'recent' list. Interface would be two-pane with an option to switch to single pane, where one pane is a list of matching records and the other is current record. List of matching records would be sortable by clicking on column titles. Going into the record would bring up a screen with title and body text of the record, if the record is a file it'd show title, list of tags and a button that opens that file. (unless it's a text file that can be viewed and edited there). The idea is to have a central hub of all information, that is very easy to search and locate not only the exact document you're looking for but also a specific subset of documents, including all of the ones you do need and excluding ones that you do not, which allows you to work with them as a set without the need to specifically select each and every one you need. For the first version it'd be enough to have plain text body field. Later I'd like to have a rich document format, probably html. Later I'd also like to add an option for matching synonymous words to tags. If you search for certainty, it would match assurance tag if the option is on. For instance, if I wanted to find this message, I'd search for Usenet posts, tag, my name (as author). I would know that I only made one Usenet post about tags. If I made unrelated posts about html tags, for instance, I'd filter by 'information manager', and then I'd find this post and more posts that I might make about this. If I wanted to include possible replies, I'd remove my name from filters. Then I could sort by date to see latest posts. The reason for this idea is that right now I keep my information, or at least most of it, in an outliner program called treepad. It's a tree-like view program where you make a hierarchical structure similar to file system, where each 'file' is a text entry field. This is reasonably useful but is limited to only one possible subset, i.e. you could put all posts under 'Usenet posts/info manager/a, b, c' but it's impossible to filter it further or to combine it with some subset of a different topic. Many chunks of information belong to multiple topics and you can't always remember if you filed under one or the other. Therefore I think this tag-based approach would be much more flexible. I have experience with doing a few simple apps in Tkinter and also a db driven site in TurboGears. I'm not sure what framework I should use for this. I generally would prefer gtk because of responsiveness and nice looks, but it may be a bit tough since I never did any gtk development at all. Should I prototype in Tkinter? Would Django be better suited for this or TurboGears? Of course there isn't any need to do anything if there is already an app that does this. Please tell me if it does, or if there is something very close that could have this set of features added easily. I was thinking about wikis, in fact. I might be best off starting with a wiki done in TurboGears and going from there. I'd get html markup pages right away, with links, nice formatting.. TG has many components that could be useful for this app. -- http://mail.python.org/mailman/listinfo/python-list

Open a file with default handler app?
Hi, I searched for this on google and in this group, but my awesome
google-fu powers failed me. Is there a way to open any file using
default program that'd open it? In other words, to do the same action
as double-clicking in windows explorer? And secondly, is there a way
to do the same thing for linux that'd work across all desktop
environments and distributions, or at least in all major ones? What
I'm trying to do here is to have records (or items) in my app where
you could attach any kind of file and open it from there by clicking
'open'. Then it would go and do something like os.system("launch %s" %
filename). So any way to do this except for keeping your own
dictionary of file types and relevant apps? thx, -ak

escape string to store in a database?
Hi, I'd like to store chunks of text, some of them may be very large, in a database, and have them searchable using 'LIKE %something%' construct. These pieces of text may have single and double quotes in them, I tried escaping them using re module and string module and either I did something wrong, or they escape either single quotes or double quotes, not both of these. So that when I insert that text into a db record, this causes an error from the database. What's the accepted way of dealing with this? I have a workaround currently where I encode the string with b64, and then unencode it when searching for a string, but that's a dumb way to do this. For my app, searching quickly is not very crucial, but would be nice to have.. thanks, -ak -- http://mail.python.org/mailman/listinfo/python-list

What you want to do is either 1. load everything up into a string,
replace
text, close file, reopen it with 'w' flag, write string to it. OR if
file is too big, you can read each line, replace, write to a temp
file,
then when done move the file over the old one.
I think there are technical reasons why file-reading and iteration api
are not very suitable for reading and writing at the same time. I
think
you'd have to set the filepointer back one line (it can be manipulated
by giving it bytes ahead/back, so that would be difficult in itself),
then delete the line and then write new string. It may be even harder
than
