Re: Terminal-based text editor with color syntax hilighting

I remember seeing vim in color over a terminal, and if I recall correctly, it can write colored source to HTML too... Unfortunately, I have such a hard time with vi - I feel like I have to RTFM every time I use it again. ;) Found some information about text terminal colors for emacs here: http://www.gnu.org/manual/elisp-manual-21-2.8/html_node/elisp_469.html Are there any others? What about Fte, I wonder... is that editor/IDE still being actively maintained? According to their website it supports Python color hilighting, but I'm not sure if the s-lang version does. I'll check into it. Thanks, Dave

Smoke: an automated build, regression and performance tracking toolset Presented by Trent Mick Tuesday April 1, 2003 7:00 PM ActiveState, 580 Granville St. Smoke is a SQL-backed client-server system used to manage information about builds of software packages as the source code base evolves, which builds pass, which regression tests pass, and how performance metrics evolve with the software.

PyQt QTableItem inheritance...
by Mike Meyer April 1, 2003

April 1, 2003

I've already tried posting this to the pyKDE mail list, and gotten no response. I'm trying to create an item in a QTable that uses the QDoubleValidator on the input edit field. The only way I can see to do this is subclass QTableItem, and override createEditor with a method that sets the validator, like so: class Float_Field(QTableItem): def __init__(self, table, data): print "Creating float field." QTableItem.__init__(self, table, QTableItem.OnTyping, str(data)) def createEditor(self): print "createEditor" editor = QLineEdit(self.text(), self.table().viewport()) self.connect(editor, SIGNAL("textChanged(QString &)"), self.table(), SLOT("doValueChanged")) editor.setValidator(QDoubleValidator(self)) return editor While I get the output from __init__, I never see the output from createEditor. Any help would be appreciated. Thanks, <mike -- Mike Meyer <mwm(a)mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.

Debug python for Windows?
by Sean Slattery April 1, 2003

April 1, 2003

Neither ActiveState nor the .exe provided at www.python.org have debug versions of python. Also, the build instructions provided with the .tgz for windows (PCbuild/readme.txt) are pretty skant and contain no clues as to how one should go about getting a complete debug python installation. Does anyone have either a binary, or better instructions for compiling a complete debug python under windows?

Re: PySqlite for the Python 2.3a

[...] David, I've now uploaded *unsupported* binaries for Python 2.3 alpha2 on Windows of the following to my homepage: - CVS snapshot of PySQLite as of today - CVS snapshot of pyPgSQL as of today - build of egenix mxDateTime 2.1beta5 (zip file) You can grab the goodies at: http://ghaering.de/python/unsupported/ "Unspported" means I'm only interested in bug reports against released versions of Python (2.1.x or 2.2.x) or PySQLite/pyPgSQL in combination with a released mxDateTime version. Bugs in the combination of a pre-release Python, pyPgSQL/PySQLite *and* mxDateTime are just too hard to track. Otherwise, have fun playing with the new 2.3 features :-) -- Gerhard

How to use dates with pysqlite
by Otto Tronarp April 1, 2003

April 1, 2003

Hi, I can't get dates to work with pysqlite. I was under the impression that it should autmatically cast columns of type date to a mx.DateTime if I hade mx.DateTime installed. However when I do a select from the database I always gets a string back. Any ideas of what I do wrong? Python 2.2.2 (#1, Mar 12 2003, 09:06:07) [GCC 3.2.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sqlite >>> from mx import DateTime >>> >>> con = sqlite.connect('testdb', autocommit=1) >>> cur = con.cursor() >>> cur.execute('create table test (d date)') >>> d = DateTime.Date(2003, 03, 31) >>> print d 2003-03-31 00:00:00.00 >>> cur.execute('insert into test values(%s)', d) >>> cur.execute('select * from test') >>> r = cur.fetchone() >>> print r ('2003-03-31 00:00:00.00',) >>> print type(r[0]) <type 'str'> >>> print type(d) <type 'DateTime'> >>> I would expect type(r[0]) to return the same as type(d) here.

Visual Python without ActivePython
by David Bolen April 1, 2003

April 1, 2003

I was looking to evaluate Visual Python, but was wondering if anyone knew a way to get it to operate with a regular distribution (not ActiveState's ActivePython) since it seems to check specifically for ActivePython on startup. I've already got 5 versions of Python installed on my system (and have carefully picked which ones get involved in the few single-use registry settings), and would prefer not to need ActivePython just for an evaluation (not to mention I'm not sure what registry "adjustments" installing it might do for free). I'd expect my standard 2.1 or 2.2 installation, including win32all, should be more than sufficient to run Visual Python.

ANNOUNCE: SCons 0.13 (build tool in Python) is now available
by Steven Knight April 1, 2003

April 1, 2003

SCons is a software construction tool (build tool, or make tool) written in Python. It is based on the design which won the Software Carpentry build tool competition in August 2000. Version 0.13 of SCons has been released and is available for download from the SCons web site: http://www.scons.org/ Or through the download link at the SCons project page at SourceForge: http://sourceforge.net/projects/scons/ RPM and Debian packages and a Win32 installer are all available, in addition to the traditional .tar.gz and .zip files. WHAT'S NEW IN THIS RELEASE? Release 0.13 contains an important fix for a critical bug found shortly after SCons version 0.12 was released. SCons version 0.12 has a bug that occurs when a build directory is used without duplicating source files in the build tree ("BuildDir(duplicate=0)") and any subsidiary SConscript file includes another SConscript file. This bug has been fixed in version 0.13, and a test has been added to the regression test base to catch this situation in the future. Release 0.13 also contains an unrelated fix to support fetching files using earlier versions of Perforce that don't use the Windows registry. ABOUT SCONS Distinctive features of SCons include: - a global view of all dependencies; no multiple passes to get everything built properly - configuration files are Python scripts, allowing the full use of a real scripting language to solve difficult build problems - a modular architecture allows the SCons Build Engine to be embedded in other Python software - the ability to scan files for implicit dependencies (#include files); - improved parallel build (-j) support that provides consistent build speedup regardless of source tree layout - use of MD5 signatures to decide if a file has really changed; no need to "touch" files to fool make that something is up-to-date - easily extensible through user-defined Builder and Scanner objects - build actions can be Python code, as well as external commands An scons-users mailing list is available for those interested in getting started using SCons. You can subscribe at: http://lists.sourceforge.net/lists/listinfo/scons-users Alternatively, we invite you to subscribe to the low-volume scons-announce mailing list to receive notification when new versions of SCons become available: http://lists.sourceforge.net/lists/listinfo/scons-announce ACKNOWLEDGEMENT Special thanks to Charles Crain for making this release possible by finding and fixing the critical bug fixed in this release. On behalf of the SCons team, --SK

Parsing C
by Daniel Timothy Bentley April 1, 2003

April 1, 2003

Hey, I find myself having to write a C interpreter in Jython. Are there any useful C compilers that are open-source in python? Or compiler-compilers that have files for a C compiler available? Or, compiler-compiler-compilers that have files for a compiler-compiler that have files for a C compiler available available? Really, I'm looking for a way to get a C compiler and mildly painlessly build it to create the AST that my program will look for. Oh, and the lexer in addition to the parser would be nice, but I bet it's all easy and fully of re-goodness in {p|j}ython. Thanks in advance, Dan
