[ANN] pyx12-1.4.0 released
pyx12-1.4.0 is available at http://pyx12.sourceforge.net/ What is Pyx12? == Pyx12 is a HIPAA X12 document validator and converter. X12 files are a form of electronic data interchange. The HIPAA transaction standard requires certain types of healthcare data to be transmitted in this form. Pyx12 parses an ANSI X12N (Healthcare) data file and validates it against a representation of the Implementation Guidelines for a HIPAA transaction. By default, it creates a 997 response. It can also create an HTML representation of the X12 document or can translate to and from several XML representations of the data file. What's New: === This is primarily a feature release: Run-time Map Customization: The validation specifications for each X12 transaction are contained in XML files (map files). For a particular transaction, the map file describes the loops, segments, and elements; their relationships, their requirement conditions; and their data types. As XML files, their contents can be altered using XSL transformations. The parsing and validation of an X12 document can be altered by giving one or more XSLT files as command line arguments. The XSLT files are applied to the correct map for the X12 document in turn. Using this feature, the validation of the document can be made more or less restrictive. The XSL transform should be written so that it only affects the intended map file. Applying the XSLT to any other map should result in no change. Also, the resulting XML map must validate against the XML Schema file 'map.xsd'. Regular Expression Element Value Validation: XSL transforms can also be used to apply a regular expression to a map element node. This allows further element value validation. See example XSLT files in %PYTHONDIR%\test\files and the XML Schema file 'map.xsd' for more details. For syntax, see python regular expression syntax. Windows installation using the python generated EXE file has been fixed. Map location lookups have been fixed. See http://pyx12.sourceforge.net/install.html for more information. The original maps (pre A1) have been removed from the package. XML Schemas for the maps and for dataele.xml have been created. Non-conforming maps have been fixed.

ANN: Front Range Pythoneers Meeting, Wed, May 16, 6-8 PM, in Boulder, Colorado - Weather Research with Python
== Meeting: Wednesday, May 16, 2007 == * Time: 6-8 PM * Location: bivio Software, Inc., 28th and Iris, Boulder, CO. Above Hair Elite in Suite S. There is abundant parking. This coming Wednesday, May 16, we have two researchers from the National Center for Atmospheric Research (NCAR) in Boulder presenting how they use Python as part of their weather research: * Joe VanAndel will present Linux and Python at 20,000 Meters Above the Sea, a NCAR/CNES dropsonde project that investigated the hurricane formation zone off the west coast of Africa. After introducing the driftsonde project, he will discuss how Linux was used in the on-board gondola computer and explain how using the Python programming language facilitated reprogramming the gondola in the middle of a flight. * Mary Haley will present Python Frameworks for Geoscience Visualization and Analysis. PyNGL and PyNIO are Python interfaces to a widely popular software package called the NCAR Command Language (NCL) for the access, analysis, and high-quality quantitative visualization of geoscientific data. Mary will briefly discuss NCL's history, and then segue into why Python was chosen for developing the next generation framework tools for file input/output, analysis and visualization. She will show an animation from a new high resolution Community Climate System Model (CCSM) run computed on a T341 grid (1024 points in longitude by 512 points in latitude) that was created using NCAR's new Python interfaces to NCL and other post production utilities. Some upcoming events you might be interested in: * Front Range Code Camp. Saturday, May 19. This would be an good setting to have a Python code jam. * Pythoneers Meeting, June 18. Steve Bethard from CU will present on Python and Natural Language Processing. * SciPy 2007 Conference, Aug 16-17. Held on the CalTech campus in Pasadena, CA, Aug 16-17. The deadline for abstracts is June 29. We will have food drink available as usual. This includes our usual free beer! Hope to see you there Wednesday!

Re: SQLObject 0.9.0
For reasons others will know, there are different branches to the SQLObject project. I think, analogously, python still has an active 2.4 branch, if that helps make sense of maintaining branches based on versions. I'm not sure why the announcements aren't bundled into one because just about everyone who sees this for the first time asks the same question. For the community being addressed (namely, users of SQLObject), this form provides a useful service: - they know that three branches are actively being maintained (0.7, 0.8, and 0.9). I would expect that in particular users of the 0.7 branch are glad to see that 0.7 is still alive even though 0.9 was just started. This is indeed more than is common, so releasing 0.7.7 simultaneously sends a clear message of affirmation (I explicitly looked for a notice that this would be the last 0.7 release, and found none) - for each branch, there is a list of changes for the branch, and I can easily see what changed in the version I'm interested in. Googling for old release announcements (e.g. SQLObject 0.7.5) brings up the announcement on hit 2, so I can also easily find announcemnts if I missed one. Those not using SQLObject, or even see this for the first time, this form gives the project higher attention than other projects - so it may attract users. It may also shy away users if they think this obsessive form of sending three usenet articles in a single hour is spam, but I guess the author is willing to take that risk.

Re: Change serial timeout per read
[EMAIL PROTECTED] wrote:
What I actually want to do is to respond immediately if the expected
string comes in, but not raise a timeout unless it takes longer than
the maximum time. So if the device I'm communicating with usually
responds in a second, but _can_ take up to 20 seconds, I don't want to
do a sleep(20) then read the port since this will slow everything down
a lot in an average world. I want to keep checking for the expected
string, and act upon it as soon as I've got it, only raising a timeout
if I haven't got it after 20 seconds. I guess to do this using non-
blocking calls I have to do something like:
timesofar = 0
returnstring = port.read(1)
while len(returnstring)expectedlength:
if timesofar = timeout:
raise SerialException('Timeout')
time.sleep(checkportinterval)
timesofar += checkpointinterval
returnstring += port.read(1)
This seems rather messy. What I've tried this morning is to produce a
modified version of uspp with a second optional timeout parameter in
its read() function. If this is present, the timeout given is sent to
the port using SetCommTimeouts(). If it's not present, the timeouts
specified when the port was opened are sent. At first sight, with
minimal testing on Windows, this seems to be working, and will leave
my application code a lot cleaner than the non-blocking plus sleep
approach. Of course I don't know whether my method will work on Linux,
and there may be problems I haven't found yet.
If it works it works - no problem with that - fight the
dragons as you meet them, one at a time.
I normally put something like this in a read function
(from memory, not tested):
error = 0
k = ''
try:
k = port.read(1)
except IoError:
error = 1
return error,k
For this to work, you have to first unblock the port using fcntl:
def unblock(f):
given file f sets unblock flag to true
fcntl.fcntl(f.fileno(),f.F_SETFL, os.O_NONBLOCK)
Then you put a call to the read in a loop, and use time.time()
to do your time out, resetting a start_time variable at the start,
and every time you get a char, and using short sleeps
(millisec or so) after unsuccessful calls to make it less of a
busy loop.
The side benefit of this is that once you have received a char,
you can change gears and use a shorter time out to detect the
end of message, in a protocol and state agnostic way. - when
the device has stopped sending chars for a little while it has
finished saying what it wants to say. - so its easy to write a
get_a_reply routine with variable time out, moving the action
from the char to the message level:
start_time=time.time()
s = ''
while time.time()-start_time time_out:
error,k = get_a_char(port)
if error:
time.sleep(0.001)
continue
s += k # keep the first char
start_time = time.time()
while time.time() - start_time 0.005: # inter char time out
status,k = get_a_char(port)
if error:
time.sleep(0.001)
continue
s +=k
start_time = time.time()
break
return s # return empty string or what was received
Something similar works for me on Suse Linux - not sure if
fcntl works on windows.
And no it isn't pretty. - but then very little of what I write is...

In the rule-file i have HHMM(start) and HHMM(stop) - 0 0 to disable hours check (i can't check the timestamp in logfile cause not all the logfiles that i need to check have a timestamp in it). In the script i wrote: Actualtime=datetime.datetime.today().strftime(%H%M) if (startend): if (Actualtimestart): end=int(Hcheck)+1 else: if (int(Actualtime)int(end)): start=Actualtime if ((int(Actualtime)int(start)) or (int(Actualtime)int(end)) or ((start==0) and (end==0)) ): rule=error ...blablabla else: rule=skip blablabla Why i don't use the complete date with YYMMDDHHMM?

If i use also yymmdd, in the rule file i need to write a 2000 and 0400+1, the +1 to tell the script that the end is in the day after, to add a day.

vim e autoindentazione commenti
Ciao a tutti, alla fine dopo le mille dispute emacs vs vim mi sono messo a provarli entrambi... e mi pare ora di essere diventato un vimmaro (pur se molto 'custom' in quanto lo sto rendendo un bel po' + simile a cream). Una domanda stupida. Forse è più da comp.editors. Come faccio a far sì che vim prosegua automaticamente i commenti su più righe? Ho settato la lunghezza massima della riga a 79 caratteri, fin qui tutto ok, ma quando vado a capo, anche se la riga inizia con #, vim non lo aggiunge in automatico all'inizio. Al contrario con altri tipi di file (es. Java) questa aggiunta è automatica e la trovo molto, molto comoda.

Re: setting extra data to a wx.textctrl
On May 10, 10:51 pm, Pom [EMAIL PROTECTED] wrote: Hello group! I have an application which uses a lot of mysql data fields, all the same data type (floats). I created a panel which executes a SELECT * FROM tablename and makes as much fields as needed, using de cursor.description as wx.statictext and the cursors field contents copied into wx.textctrls. At creation time, I loop over all the fields in the record and create a tuple which contains ((textctrl1, fieldname1), (textctrl2, fieldname2), ...) so I can keep track of which textctrl holds which piece of fielddata. The problem I'm having is: to know the fieldname in an text_event, I use event.GetEventObject(), then perform an iteration over the tuple and when I find a match I use the field name to update the mysqltable. When having a few fields, this is ok. But I have over 100 fields in 1 record and it really slows things down. Now my question is: should I use a python dictionary (with an object as first lookup field) ? On windows, I've seen a Tag property in a textbox which was meant to be used for this kind of stuff. Maybe it's better to override the wx.textctrl so I can add an extra string value? Anyone having the best solution for this ? thx! Both of your ideas seem sound to me. You could also look into using statically assigned IDs that increment by one. Then you could just increment or decrement by one and look up the field by ID. Of course, that might get ugly and there are some IDs that are supposedly reserved. But it's an idea. Also, I've heard that Dabo (http://dabodev.com/) is good for database work.

Dyla'07: 3rd Workshop on Dynamic Languages and Applications
Dear colleague, Please, note that after the workshop, best papers will be selected, and a second deadline will then be set regarding preparation of the Electronic Communications of the EASST. Note that we submission deadline has been extended. The important dates: - May 27: deadline for the workshop submissions. Submissions should follow LNCS format (www.springer.com/lncs) and should be sorter than 10 pages. **extended deadline** - June 12-13: Author notification of their submission - June 15, 2007: ECOOP'07 Early Registration - July 31: Workshop - August 5: Selection of best papers for Electronic Communications of the EASST - September 10: deadline for revised and extended version of submission for the communications. Regards, Dyla organisers * Call for Papers Dyla 2007: 3rd Workshop on Dynamic Languages and Applications July 31, 2007, Berlin (Collocated with ECOOP 2007) http://dyla2007.unibe.ch * Objective = The goal of this workshop is to act as a forum where we can discuss new advances in the conception, implementation and application of object-oriented languages that radically diverge from the statically typed class-based reflectionless doctrine. The goal of the workshop is to discuss new as well as older forgotten languages and features in this context. Topics of interest include, but are certainly not limited to: - agents, actors, active objects, distribution, concurrency and mobility - delegation, prototypes, mixins - first-class closures, continuations, environments - reflection and meta-programming - (dynamic) aspects for dynamic languages - higher-order objects messages - ... other exotic dynamic features which you would categorize as OO - multi-paradigm static/dynamic-marriages - (concurrent/distributed/mobile/aspect) virtual machines - optimisation of dynamic languages - automated reasoning about dynamic languages - regular syntactic schemes (cf. S-expressions, Smalltalk, Self) - Smalltalk, Python, Ruby, Scheme, Lisp, Self, ABCL, Prolog, ... - ... any topic relevant in applying and/or supporting dynamic languages. We solicit high-quality submissions on research results and/or experience. Submitted papers must be unpublished and not submitted for publication elsewhere. Submissions should not exceed 10 pages, LNCS format (www.springer.com/lncs). Submission == Prospective attendees are requested to submit a position paper or an essay (max 10 pages, references included) on a topic relevant to the workshop to Alexandre Bergel ([EMAIL PROTECTED]). Submissions are demanded to be in .pdf format and should arrive before May 13, 2007. A selection of the best papers will be made, which will require an extension for an inclusion in a special issue in Electronic Communications of the EASST (eceasst.cs.tu-berlin.de). For this purpose, a new deadline will be set after the workshop. Moreover, Springer publishes a Workshop-Reader (as in the case of previous ECOOPs) which appears after the Conference and which contains Workshop-Reports (written by the organizers) and not the position papers submitted by the participants. Important dates === May 27, 2007: deadline for the workshop submissions.

If you're really confined to built-ins (ie you can't import

Why not?
If you can import modules, then you want to look

If a second word is provided it will be used as an id, otherwise an unique id will be build according the type of widget. the window is created with glade, widgets are provided as attributs of the instance, and signals are autoconnected on method on_[widgetId]_[event](self,*args) (if a signal is missing in your class, it warns you at run time) It will not replace the use of glade-3 for complex widget ... but I think it's an easy way to code very easily/quickly a simple pygtk window/form. I think it could be really useful/handly for beginners too. for people which are involved in pygtk/python/gui ... i'd like to hear your comments/ideas ...

You are walking the directory structure *twice*, using two different
methods at the same time. Also, there is no standard `path` module, and
several implementations around, so it would be a good idea to tell us
which one you use.
If you want to omit a directory, and include just filenames matching a
pattern:
import os, sys, os.path, fnmatch
def findinterestingfiles(root_dir):
for dirpath, dirnames, filenames in os.walk(root_dir):
if Archived in dirnames:

Depends on what you're doing exactly. I've done something like this
and it only hits the page once:
URL = 'http://quote.yahoo.com/d/quotes.csv?s=%sf=sl1c1p2'
TICKS = ('AMZN', 'AMD', 'EBAY', 'GOOG', 'MSFT', 'YHOO')
u = urlopen(URL % ','.join(TICKS))
for data in u:
tick, price, chg, per = data.split(',')
# do something with data
If you're grabbing all the data in one fell swoop (which is what you
should aim for), then it's harder for Yahoo! to know what you're doing
exactly. And I can't see why they'd care as that is all a browser does
anyway. It's when you hit the site a bunch of times in a short period
of time that sets off the alarms.

textmate and the command line use different python versions they also
search in different places..

PATH='/opt/local/lib/python2.4/site-packages/'
sys.path.append(PATH)

Just because an objecty has a true truth-value doesn't mean that it is equal to the True object. -- Grant Edwards grante Yow! Why don't you ever at enter any CONTESTS, visi.comMarvin??

Re: setting extra data to a wx.textctrl
[EMAIL PROTECTED] wrote: On May 10, 10:51 pm, Pom [EMAIL PROTECTED] wrote: Hello group! I have an application which uses a lot of mysql data fields, all the same data type (floats). I created a panel which executes a SELECT * FROM tablename and makes as much fields as needed, using de cursor.description as wx.statictext and the cursors field contents copied into wx.textctrls. At creation time, I loop over all the fields in the record and create a tuple which contains ((textctrl1, fieldname1), (textctrl2, fieldname2), ...) so I can keep track of which textctrl holds which piece of fielddata. The problem I'm having is: to know the fieldname in an text_event, I use event.GetEventObject(), then perform an iteration over the tuple and when I find a match I use the field name to update the mysqltable. When having a few fields, this is ok. But I have over 100 fields in 1 record and it really slows things down. Now my question is: should I use a python dictionary (with an object as first lookup field) ? On windows, I've seen a Tag property in a textbox which was meant to be used for this kind of stuff. Maybe it's better to override the wx.textctrl so I can add an extra string value? Anyone having the best solution for this ? thx! Both of your ideas seem sound to me. You could also look into using statically assigned IDs that increment by one. Then you could just increment or decrement by one and look up the field by ID. Of course, that might get ugly and there are some IDs that are supposedly reserved. But it's an idea. Also, I've heard that Dabo (http://dabodev.com/) is good for database work. You might look at that.

wrote in news:[EMAIL PROTECTED] in comp.lang.python: [] == [] True ['-o'] == [] False ['-o'] == False False To test wether something is true use if. To test wether something is false use if not. The python values True and False are for when you need to *store* a boolean value (for later testing). I you want to to see if an arbitry expression would test as true or false at the interactive prompt use bool(): bool([]) False bool(['-o']) True There is *never* any need to write things like: expression == True or: expression == False Once you stop doing this things will become much simpler.

Recursion limit problems
Hello everyone, I am runing into recursion limit problems. I have found that the culprit was related to the __hash__ function that I had assigned to the objects that were added to a set. Basically my __hash__ function is the following: def __hash__(self): out_int = 0 for property,value in self: out_int ^= hash( property )^hash( value ) return out_int And the iterator for this object is: def __iter__(self): for property,value in self.__dict__.iteritems(): yield property,value After commenting the __hash__ function and using the default provided by Python (I suppose it is based on the position in memory of the object), the recursion limit problems went away. (This problem was happening even after increasing the recursion limit to the maximum of my platform, MacOSX). I am not that versed in Python, so I don't know exactly I could do to overcome this problem, any ideas are deeply appreciated. Thanks! -- http://mail.python.org/mailman/listinfo/python-list
