Is there a Python Version Manager?
Having STFW and come up empty, I'm wondering if anyone knows if there is an analogue to the Ruby Version Manager http:// rvm.beginrescueend.com/ in the Python world? rvm is essentially a tool that can install several Ruby implementations side by side and easily hot swap them in your shell session. Check a few pages of their website and you will get the idea. In the python world, the closest I have seen to rvm, are tools that just archive a (C)Python distribution around your project. Not what I need. Why I ask, is after years of using systems that package *modern* versions of Python, I'm now stuck with a work station running 2.4 as latest and greatest! Personally I draw the line at supporting 2.6, 3.1, and otherwise YMMV -- that means building and maintaining my own builds outside the OS'es package management is going to become a reality real soon, not to mention a pain. So something like rvm but for Python, would be a real life saver in my near future. and if writing a Python analogue to rvm is necessary, would anyone be interested in helping with such a project? -- http://mail.python.org/mailman/listinfo/python-list

Even more, if I use IDLE, running scripts fails. However, if I _first_ type from PyQt4 import QtGui in the python shell, the script executes without problems.

Everything that you import however, is basically the name of a .pyd and .dll file there. E.g. from pyQt4 import QtGui = there is a QtGui.pyd and QtGui.dll module. The .pyd file is what you're really importing, but I don't recall the relationship to the dll files clumped around it. You can probably find it in the python or windows manuals somewhere.

Thanks for being patient. Jeremy launching external programs, irregardless of language, generally falls into 3 major categories: 0.) blocks until program is done; like system 1.) replaces your program with process, never returns; like exec 2.) quickly return after asynchronously launching the program Most languages will implement the first method because of the standard system() function in C, which is fairly popular in it's own right. Most multi-tasking operating systems will implement some form of exec function, which Python exposes through the os module. The last method is the least portable, because obviously if the OS lacks multi-tasking you're screwed. The best examples of 2. are the UNIX popen() function and Microsoft's spawn() family, when used with the P_DETACH flag. Python being made with much loving kindless, exposes each interface. More system specific functions are exposed through the os module in a fairly portable way in so much as is actually possible under Unix and Windows. The standard subprocess module provides a portable Popen class and a few convenience functions for all occasions - including good documentation on how to use it to establish the common goals most people will ever have, when wishing to invoke an external program.

Most of what you refer to are **separate operating system specific programs** and have absolutely nothing to do with the shell. Very sophisticated scripts are possible using bash and ksh, there is even a form of ksh that has tk capabilities! (tksh). The Python and Bourne-derived languages are however fundamentally different creatures, and use very different data models. You should **not** write Python (or Perl) scripts as if they were shell scripts -- doing so is very bad practice. When you want a shell script, write a shell script. When you write a Python script, write a Python script. It really is that simple. As a rule of thumb, when you have need of data structures beyond what scalar strings and very simple word lists can provide -- you should use Python. bash and ksh provide support for arrays, and ksh even has dictionaries! (Hashes in Perl speak.) That makes programming in bash/ ksh more robust then pure sh, but also less portable. The best time to use bash is when you require bash specific features, other wise don't use bash. The same can be said for ksh. When the words array, dictionary, class, object, and/or using multiple source files comes to mind when implementing a program - you probably want to use Python, Perl, Ruby, or some other general programming language, not a shell scripting language like bash. You should be cautious to avoid mixing bash and Python code in one file.

I tend to write programs that understand EDITOR, BROWSER, etc; wish the rest of the world did. So what does the intervening custom layer do before directing the remote vim to edit the file? Or is it something that comes in handy when the client does not undertand environment variables? Nothing really, it only does what it was tasked with. Last compiled source: http://pastebin.ca/1611045 which was built out of a msvc project in some measure of haste. I noticed that 'clientserver' vim provides a few functions, presumably to make the process more flexible. But these functions are vim-specific, naturally, so wouldn't this suggest a client vim + server vim setup? IOW, apart from adding logic to the process of selecting the server, I don't really see much else the vim client would be able to do once it has directed his request to the server. OTOH, some of these functions, such as server2client(), and the matching remote_peek() remote_read() look promising but unless I missed something, I didn't see anything about an API that would let me call them outside the context of vim. C:\Documents and Settings\Terrygvim --servername TEST C:\Documents and Settings\Terrygvim --servername TEST --remote-send :!start no tepad sucksCR works as expected. Maybe part of what makes the whole thing so confusing, to me at least, is that I can't fall back on anything I've seen before, where both the client (vim instance or other application) and the server interact with the user. I assume using vim in client mode, only serves to send data to the server via some pre defined OS-specific method before exit()'ing. I can think of one particular scenario where the added complexity and overhead would be more than counterbalanced when using a client server setup, making for instance a system administrator's chores a lot easier when he has to work with the same configuration file(s) on a number of systems, giving him the ability to edit them in a single 'central' instance of vim, with the benefit of easy diff'ing, cut'n'pasting, running custom scripts, etc. With ssh remote X that's probably not too hard to set up in a way that's sufficiently user-friendly. Somehow, I doubt vim's clientserver feature is any where near as powerful as the Id Tech 3 engine mates client and server, but then again they service different problems ^_^. Even though I only tried with the client application and the vim server running on the same machine, I've had mixed results in this respect: Everything appeared to consistently work without a glitch as long as I made sure that I had the client wait for the vim server to unload the buffer(s), but there were some pretty strange results as soon as I dropped the 'wait' bit from my requests: more often than not, I only managed to create an empty buffer on the server side, and on a couple of occasions, I even ended up with a buffer that looked just about right in terms of length, but where all the data had been converted to NULLs (0x00). I believe that clientserver may depend on access to the X display under unix, or at least it doens't works on the X'less ssh connection I tested with last week. Under Win32 it probably mucks about with winmessages or ole stuff. (Note: my primary work station is BSD, not WinNT) -- http://mail.python.org/mailman/listinfo/python-list

Re: best vi / emacs python features
I typically use several editors: /bin/ed, nvi, EDIT.COM, and Vi Improved. These are the advantages that I find these various editors give me: ed -- I can quickly edit files without having to wait on an ncurses app to start up. Although I rarely have access to GNU versions of ed, they use readline which is a big perk when you make a typo. nvi -- smaller and faster then vim, works great over slow ssh links or when editing huge files. I like nvi over the original vi, because most of the limitations of the old-school vi are removed; unlimited undo is the best feature added. EDIT.COM -- much faster then notepad over remote connections, and it understands both DOS and UNIX end of lines; meaning I can skip converting formats, the only downside is it's still a 16-bit program. vim -- My favourite and most used editor. I like it because it can be made fairly compatible with vi, but has superior tag stack handling, and the multiple-window, :ex command line history, and completion features leave their nvi equivalents in the dust. (vi had no completion or command history, and lacked split windows.) Vim also has improved register handling, regular expression support, tab pages for organizing workspaces, a client/server mode, and most importantly can be made to adapt itself (e.g. spaces, tabs, eol's) based on file type without much bother. That makes it much easier to use with Python files then most editors in my tool bag. I am a freak: I do not use nor want syntax highlighting. I don't want my editor to understand mail, irc, or the www either, I want it to edit text efficiently so I can go on with the rest of my life as soon as possible. Given the choice of using a space cadets editor like emacs or something primitive one like ed, I would choose *ed* just to speed things up and save on wrist strain.

On Oct 8, 3:29 am, Chris Jones cjns1...@gmail.com wrote: I do have a question: You mentioned Vim's clientserver mode. What's it good for? It's most valuable for sending data to an existing instance of vim, by name. Both files and keystrokes can be sent fwiw. vim basically organizes it self into buffers, windows, pages, and servers. A buffer is essentially a file, a window a look into a buffer, a page a group of windows, and a server is an instance of vim (group of pages). As a matter of standard operating procedure, I organize tab pages into module or project oriented workspaces; each page usually contains a split window: open to a source file and a corresponding header^* file. It's a work flow I got used to using for dealing with C++ and Perl code, but it is still useful for Python as well. On top of that, I sometimes group instances of vim into 'servers' by type. So for example, I may have a vim servers (instances) each for FooProject, BarPorject, and another for editing personal documents or configuration files. When I have programs that launch vim to handle editing tasks, I'll often make them send the file to an appropriate vim server, so everything is grouped accordingly. Example: when projects require the use of Visual C++, I have the IDE set to open most files with a custom program: which execs gvim --servername MSVC -- remote-tab-silent TheFileNameToOpen.ext. So that every file opened through VC will be in one GVim window. The same could be done with several webbrowsers, mail clients, and newsreaders. It makes using using vim as an external program to something fatter much more convenient. GNU Screen and a decent terminal emulator can be more handy then clientserver, when the work station supports it that is;).

Re: Comparison of parsers in python?
Peng Yu wrote: This is more a less just a list of parsers. I would like some detailed guidelines on which one to choose for various parsing problems. Regards, Peng It depends on the parsing problem. Obviously your not going to use an INI parser to work with XML, or vice versa. Likewise some formats can be parsed in different ways, XML parsers for example are often build around a SAX or DOM model. The differences between them (hit Wikipedia) can effect the performance of your application, more then learning how to use an XML parsers API can effect the hair on your head. For flat data, simple unix style rc or dos style ini file will often suffice, and writing a parser is fairly trivial; in fact writing a config file parser is an excellent learning exercise, to get a feel for a given languages standard I/O, string handling, and type conversion features. These kind of parsers tend to be pretty quick because of their simplicity, and writing a small but extremely fast one can be enjoyable at times; one of these days I need to do it in X86 assembly just for the hell of it. Python includes an INI parser in the standard library. XML serves well for hierarchical data models, but can be a royal pain to write code around the parsers (IMHO anyway!), but often is handy. Popular parsers for XML include expat and libxml2 - there is also a more Pythonic wrapper for libxml/libxslt called py-lxml; Python also comes with parsers for XML. Other formats such as JSON, YAML, heck even S-expressions could be used and parsed. Some programs only parse enough to slup up code and eval it (not always smart, but sometimes useful). In general the issues to consider when selecting a parser for a given format, involve: speed, size, and time. How long does it take to process the data set, how much memory (size) does it consume, and how much bloody time will it take to learn the API ;). The best way to choose a parser, is experiment with several, test (and profile!) them according to the project, then pick the one you like best, out of those that are suitable for the task. Profiling can be very important. -- TerryP -- http://mail.python.org/mailman/listinfo/python-list

So obviously ANSI C and the hunt for a suitable networking library to fill in the biggest time waster came to mind.
