Re: [Tutor] Plugin system - how to manage plugin files?

Then, when my app started up, it simply got a list of all the "*_plugin.py" files in the current directory, dynamically imported the files using "my_module = __import__(name)" and then I could do whatever I wanted with that module using "my_module", such as instantiate an object for each module's "Plugin" class, etc. Actually, here's a snippet of code I had lying around that I slapped together a few years ago to remind myself of how I did this.

Re: [Tutor] PyWin32 - Library of functions to interact with windows?
If I may chime in... As Alan said, pywin is basically a thin wrapper around the Win32 API. The Win32 API is very complex. Thus pywin is, by necessity, also very complex. There is documentation for pywin, but it is very minimal as you've probably noticed. If you are a *very* bold beginner with lots of patience, the best documentation for pywin is actually the documentation for the Win32 API itself found on Microsoft's "MSDN Library" website [1]. Navigating and using this documentation requires a knowledge of the Windows architecture and C programming. Once you find what you want in the MSDN documentation, you can usually find the same function in pywin. Again, this is not going to be easy if you are a beginner (it is difficult even for more experienced programmers), but I wanted to let you know the info is out there. If you want to dive into Win32 programming and learn the basics, the books Alan mentioned are good. But again, Win32 programming is pretty low-level and complex. There is usually an easier way to do most things you need to do. Especially if you want to create GUI's in Python, don't start with pywin and Win32. Use EasyGUI, Tkinter, or wxPython (in order of easiest to most powerful) Now, back to your specific task. To clarify, I'm assuming you want to color the text that shows up in Window's console when you do "print" from Python, correct? It *is* possible to color console text with Python and pywin. But, it is tricky and not obvious. I've been wondering how to do this myself and I recently found some C code on the web [2] that does this and I translated that into to Python and pywin. It can be done in about 4 lines of Python. To get you started, here is the link [3] to the MSDN documentation that tells you what you need to know about coloring text in a Windows console window (what Python's print command uses). Then, it is up to you to translate this into Python and pywin. The link [2] could also help. If you are up for a challenge, give it a shot. If you get stuck or it takes too long, write back and I/we can nudge you in the right direction with a code snippet. (While writing this email, I also discovered that you can control the cursor position in a win32 console with pywin! Fun!) Best of luck, and feel free to ask for more help! -Scott [1] - http://msdn.microsoft.com/en-us/library/default.aspx [2] - http://www.dreamincode.net/forums/showtopic23272.htm [3] - http://msdn.microsoft.com/en-us/library/ms682088(VS.85).aspx ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

[Tutor] win32gui, SetForegroundWindow() and setting focus
Greetings all... I'm looking to use the win32api and win32gui modules to do a bit of Windows tinkering (win2k) and I've hit a snag. I'd like to programmatically set which window has the focus. But win32gui.SetForegroundWindow(hwnd) seems to be what I'm looking for, but, it isn't working quite as I expect meaning I probably have a bad assumption. SetForegroundWindow() works like a charm in simple cases from the command line. However, when I enumerate all top level windows and try to set each one as the foreground window in turn, it gets thru 1-2 windows out of the 8-10 I have open before giving me this: Traceback (most recent call last): File "D:\_code\python\apps\WinTests.py", line 25, in ? cycle_foreground() File "D:\_code\python\apps\WinTests.py", line 20, in cycle_foreground win32gui.SetForegroundWindow(handle) pywintypes.error: (0, 'SetForegroundWindow', 'No error message is available') What am I doing wrong in this case? Can my app "give away" its own focus but can't force a different app's window with focus to "give away" its focus? Is there any other way to accomplish this? I've attempted using a mix of SetFocus(), BringWindowToTop(), and EnableWindow() but couldn't find the magic combo. I've attached my test script. Run it as "WinTests cycle" to attempt to cycle the focus through all top level windows and see the traceback above. Run it as "WinTests 12345" to set focus the window with hwnd of 12345. Run it as "WinTests" to get a list of all top level windows and their hwnd's. I've tried reading the very-sparse win32 docs provided with ActiveState's PythonWin, I've read a bit on the win32 API on MSDN and I've googled around a bit, and haven't found much. Thanks for making this a great list, all... -Scott import win32gui import time import sys import win32con def win_enum_callback(hwnd, results): if win32gui.IsWindowVisible(hwnd) and win32gui.GetWindowText(hwnd) != '': results.append(hwnd) def print_list(): handles = [] win32gui.EnumWindows(win_enum_callback, handles) print '\n'.join(['%d\t%s' % (h, win32gui.GetWindowText(h)) for h in handles]) def cycle_foreground(): handles = [] win32gui.EnumWindows(win_enum_callback, handles) for handle in handles: print handle, win32gui.GetWindowText(handle) win32gui.SetForegroundWindow(handle) time.sleep(2.0) if __name__ == '__main__': if len(sys.argv) == 2 and sys.argv[1] == 'cycle': cycle_foreground() sys.exit(0) if len(sys.argv) == 2: win32gui.SetForegroundWindow(int(sys.argv[1])) else: print_list() ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Which Python Script Editor of Choice?
> > Komodo also often gets props from the "IDE People" I've known. To throw another one into the mix, ActiveState has a free/open source version of its Komodo IDE called "Komodo Edit". I downloaded it and played with it for a few minutes awhile ago. Seems pretty slick. Anyone have any first hand experience with this one? It also supports more than just Python (also does Perl, PHP, Ruby, Rails, etc.) http://www.activestate.com/Products/komodo_ide/komodo_edit.mhtml (FWIW, most of the time, I use PythonWin to edit code and a command prompt to run scripts) > Btw, if people know of good IDE's other than PIDA that are free, run on windows and linux and allow use of VIM as the editor, please let me know. Looking at Komodo Edit's page, it supports Win/Mac/Linux, has "Vi emulation", and is free (not crippled in any way that I know of. It just has a smaller feature set when compared to the full Komodo). ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Providing Solutions for all the Common Questions
To throw out an idea... http://www.showmedo.com/ is a site that believes that learning-by-watching is a very effective way to teach people new skills. So, they host lots of (user-generated) screencasts (usually 5-10 minutes) that show people how to do things. Because the site is Python focused, there are 350+ videos on learning Python (150+ beginner oriented vids). Would it be helpful to take the most common questions and create screencasts that demonstre the answers to common questions, post them to ShowMeDo and get a collection of links togeher?

Re: [Tutor] Print to std output with color
Curses is one way to go. Another is to use the PyWin32 module discussed in this thread: http://thread.gmane.org/gmane.comp.python.tutor/58450/focus=58454 Basically, here's a snippet of code that can get you started. This requires that you have the PyWin32 module installed (already installed by default if you use ActiveState's Python distribution for Windows). Using PyWin32 isn't for the faint of heart, but it does work. import win32console handle = win32console.GetStdHandle(win32console.STD_OUTPUT_HANDLE) handle.SetConsoleTextAttribute(win32console.FOREGROUND_BLUE) print 'blue text' On Wed, Jan 26, 2011 at 11:10 AM, Karim wrote: > > Hello all, > > Is there a simple way to print with color to stdout like the unix/linux > example below: > > *print( '^[[1;31mThis is a warning!^[[0m' ) > > where <=> ^[ > > *I see thing with curses module.
