A wxHtmlWindow forms implementation.
by Tom B. 13 Sep '04

13 Sep '04

It consists of a pre-filter, http://users.commspeed.net/tbabbitt/tom2/HTMLparse.py usage: import HTMLparse,urllib2 TomFilter = HTMLparse.TomFilter() webtext = urllib2.urlopen('http://www.yahoo.com') formtxt = TomFilter.formfilter(webtext,'http://www.yahoo.com') # after feeding imagelist = TomFilter.imagelist linklist = TomFilter.linklist scripttext = TomFilter.scripttext linktextlist = TomFilter.linktextlist background = TomFilter.background backgroundcolor = TomFilter.backgroundcolor The parser, completes URL's, changes form tags to custom wxControl tags and mangles frames into rows of tables. (note encoding('utf_8','ignore'). The next part is a custom module for web controls. http://users.commspeed.net/tbabbitt/tom2/webwig.py The controls post there events to a custom event and are available as a class called WebEvent. (Note Radio buttons are implemented as check boxes so you have to uncheck at the event end.) The only thing left to be done is to link the events to the program running the wx.html window. import wx import wx.html as html import wx.lib.wxpTag import webwig def __init__(self): ....self.Bind(webwig.EVT_UPDATE_WEBFORM,self.OnPyEvent) ....self.WebObjects = {} def OnPyEvent(self, event): ....self.WebEvent = event.GetVal() ....if self.WebEvent.Typ[:4] == 'int_': ........self.WebObjects[self.WebEvent.Id] = self.WebEvent ........self.WebObjects[self.WebEvent.Id].Typ = self.WebObjects[self.WebEvent.Id].Typ[4:] ....else: ........self.WebObjects[self.WebEvent.Id] = self.WebEvent This gives you a WebEvent object and dictionary of all web objects on page. WebEvent objects have the following properties, self.WebEvent.Name # the control name self.WebEvent.Value # the control value self.WebEvent.WebValue # in the form u'&%s="%s"' % (Name ,Value ) self.WebEvent.URL # the full URL self.WebEvent.FormData # the full Form data in dictionary self.WebEvent.Data # extra data from select and data from hidden, in form 'action'|'http://'|'method'|'POST' ect. self.WebEvent.Id #the controll Id self.WebEvent.Win # the control itself Here is code for the Demo (love the new demo). http://users.commspeed.net/tbabbitt/tom2/demowebwig.py I have also written a program to display its features it requires, PIL , http://www.pythonware.com/products/pil/ image_view (ScrolledWindow PIL viewer) http://users.commspeed.net/tbabbitt/tom/image_view.py the Browser http://users.commspeed.net/tbabbitt/tom2/TomBrowse.py Inspired by the demo it separates the web page components into notebook pages and runs the Content of a STC through the above event. Errors are displayed on a log page. I know how much people have wanted something like this so I just want to get the code out there. The tag handler complains on pages with hidden tags but I can find nothing wrong with my tag syntax. There is an unhanded exception when I use the SetPage from the event definition but when the page is saved it loads back ok so I probably need to destroy the web objects on the event end. Infinite Abundance, Tom Babbitt

ANN: ProfitPy 0.1
by Troy Melhase 11 Sep '04

11 Sep '04

ProfitPy - An Automated Stock Trading Toolkit for Python ============================================================================= ProfitPy 0.1 Released 11 September 2004 What is ProfitPy? ----------------------------------------------------------------------------- ProfitPy is a set of libraries and tools for the development, testing, and execution of automated stock trading systems[1]. The main web site for the toolkit is here: http://profitpy.sourceforge.net/ Specifically, ProfitPy is a collection of Python packages, modules, and scripts that work together to help you implement an automated stock trading program (or programs). The package features: * A library with classes for accounts, orders, tickers, and more * A GUI program for executing and plotting trades in real-time[2] * A GUI tool to collect ticker data for off-line use * A CLI tool to back-test trading strategies * Dozens of technical indicators and plotting widgets to display them * An X11 keystroke tool for automating the TWS application Screenshots ----------------------------------------------------------------------------- A picture is worth a thousand words. It beats documentation, at least: http://profitpy.sourceforge.net/screenshots.html Where can I get ProfitPy? ----------------------------------------------------------------------------- ProfitPy is available for download from SourceForge: http://sourceforge.net/projects/profitpy What are the requirements? ----------------------------------------------------------------------------- ProfitPy requires the following packages. Newer versions may (or may not!) be substituted: * Python 2.3.4 http://www.python.org/ * PyKDE 3.11.3 http://www.riverbankcomputing.co.uk/pykde/ * PyQwt 4.0rc0 http://sourceforge.net/projects/pyqwt/ * SciPy 0.3 http://www.scipy.org/ * IbPy 0.4 http://sourceforge.net/projects/ibpy/ ProfitPy can make use of these optional components as well: * The Eric3 Python IDE http://www.die-offenbachs.de/detlev/eric3.html The ProfitPy main GUI features a source code viewing widget. If the Eric3 IDE is present and importable, its source editor widget will be used instead. * X11::GUITest http://sourceforge.net/projects/x11guitest The main GUI and the collection tool make use of a keystroke automation script for TWS. This script requires the X11::GUITest Perl package. ProfitPy applications and tools connect to the Interactive Brokers[3] client application to receive data and send orders. This system, TWS, requires a web browser capable of executing Sun(R) Java(tm) applets. TWS can also be started directly with Sun(R) Java(tm) and the stand-alone package supplied by IB. What is Python? ----------------------------------------------------------------------------- >From the "What is Python?" page (http://python.org/doc/Summary.html): Python is an interpreted, interactive, object-oriented programming language. It is often compared to Tcl, Perl, Scheme or Java. Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac, MFC). New built-in modules are easily written in C or C++. Python is also usable as an extension language for applications that need a programmable interface. The Python implementation is portable: it runs on many brands of UNIX, on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't listed here, it may still be supported, if there's a C compiler for it. Ask around on comp.lang.python -- or just try compiling Python yourself. The Python implementation is copyrighted but freely usable and distributable, even for commercial use. What is TWS? ----------------------------------------------------------------------------- >From the page "Trader Execution and Clearing System Features" (http://interactivebrokers.com/html/companyInfo/market_ib.html): * IB's Trader Workstation can be run directly from your browser, or you can install it on your PC and run it from your desktop. This Java based application allows traders to quickly enter orders and see results. * Direct Access: Unlike other "online" brokers that send your order through an e-mail type system, IB offers a direct-access order entry system that transmits your order to the proper market center, usually within one second of entry. * Real-Time Streaming Quotes: Display real-time, streaming quotes for markets of interest to the investor. Quotes are live and change continuously as the markets change, no periodic manual update or "refresh" is required. What else? ----------------------------------------------------------------------------- ProfitPy is Free Software and is concordantly licensed under the GPL. Refer to the LICENSE file in the distribution for more information. I never intended to release this code to the public. Much of it is specific to my trading applications. Please note that the superficial design flaws are very important, as they hide the fundamental ones. YMMV. ProfitPy is not a product of Interactive Brokers, nor am I affiliated with IB. I am a satisfied IB customer, of course. The TWS demo system is available here: http://interactivebrokers.com/cgi-pub/jtslink.pl?user_name=edemo Thank you! ----------------------------------------------------------------------------- Thank you, for I am very interested in your experience with ProfitPy. Please drop me an note with any feedback you have. -- Troy Melhase, troy(a)gci.net -- I am the Christian the Devil warned you about. [1] I trade stocks, not futures, options, or anything else, just stocks. ProfitPy reflects this, but I know of nothing that limits the code to only stocks. [2] Please excuse the misuse of "real time". I understand that none of this is true real time. [3] Interactive Brokers website: http://www.interactivebrokers.com/

m3ute2 0.2.0.0 (first public release!)
by Jody Burns 09 Sep '04

09 Sep '04

m3ute2 is a command-line tool for copying lists of files (or directories, or single files) with extensive filename-level filtering options. http://sf.net/projects/m3ute2/ m3ute2 is a program I developed in order to copy subsets of my music collection from my desktop computer to my laptop so I could listen to it while on the road. It has grown from that humble beginning to encompass a variety of features that give the user fine control over how files are copied. It also can tell you if there is enough space at the destination for the files you want to copy. m3ute2 can resume, skip, or entirely overwrite partially copied files. m3ute2 locks both the source and destination file during copying so that file corruption is less likely to occur. m3ute2 can apply user-supplied regular expressions or standard UNIX filename matching patterns (such as the classic '*.*') when determining if a specific file will be copied. m3ute2 can create reports about lists of files before you copy them to give you statistical information about the files and estimations about how long the copy operation will take and how much space will be used at the destination. m3ute2 will warn you if you attempt to copy an amount of information which exceeds the usable capacity of the destination, either through physical limitations or disk usage quotas. m3ute2 can also interface with the SysInternals contig.exe file defragmentation tool when copying to a local volume so the files at your destination will be as contiguous as possible. m3ute2 is implemented purely in Python and is distributed in both source and Windows binary installer forms. m3ute2 currently only works on Windows 2000/XP/Server 2003 but porting it to a POSIX system would be a small task and we would welcome any suggestions or help the community has to offer on this subject. Come check it out! m3ute2 is GPL'd and we'd love comments or suggestions. http://sf.net/projects/m3ute2/
