Wayne Watson sierra_mtnv...@sbcglobal.net wrote My assumption was is was fully a DOS window. No its a DOS window on steroids!

Re: [Tutor] Looking for ConfigObj Documentation
As it turns out QuickEdit is turned on in my XP, but certainly not by me. The unfolding of what the cmd prompt actually does reminds me of a couple of incidents. When I wrote a book on an interpretive Basic language in the early 90s, the very first paragraph began with how to exit from the interpreter. At the time, it seemed popular with such interpreters to obfuscate the exit command by using names like SYSTEM! Yikes! When I was introduced the C by the Kernighan and Ritchie book, I almost jumped for joy with their famous "Hello World" program. This was a book to be read. When I casually, and I mean casually, started looking at python a few years ago, I started with what I might call a (well-known) bloated book on the subject, it took until chapter 3 for the author to say anything about running programs. The first programming job I had found me staring at a government issued 200 page manual printed in capitals on a then popular language. What a huge bore. It's a wonder that I continued, or anyone, for that matter. I guess the right start matters, or in the words of the hero in Schindler's List (movie), "It's all about presentation." After this cmd console "discovery", I'd say this is quite possibly something I'd put in the first chapter of any book on Python. Nice to know about F8 (and F7), tab or other attempts didn't do it for me. I'll take Alan's suggestion on spending some time on the reading XP Help.

Re: [Tutor] Looking for ConfigObj Documentation
Title: Signature.html Yes, to a potential bad idea. I'm not quite sure why I put that in there. Possibly what I really wanted is the location of the file. There are some other entries where I want to know the location of the file. For example, the mask file. I likely want to load that file when the program opens. Similarly with the Events folder. In fact, I probably want the folder's name chosen by the user, and the location. Folders and files are not completely thought out. The hard core data, time, gray choice, lat/long, etc., are currently the most important. Distracted? It happens to me all the time?:-) I tell people my life could be summed up by two words, interrupted projects. I could very likely build the file myself from looking at the descriptions of boolean, etc., but you mentioned something about possibly a validation function(?) that sounded like maybe I didn't yet know all the wrinkles in the file.

As far as I can tell, line 1 of config.obj looks OK. It's a comment. Something is amiss. I hate to say it, but IDLE is really holding you back. It's convenient because it installs automagically with Python, but it does funky, confusing things - as in this case, where it's somehow stepped on the real error and assigned blame in the wrong place; you've already experienced its internal conflicts with Tkinter... I use wxPython for my GUI goodness, and swear by SPE (Stani's Python Editor). I don't want to re-ignite the IDE wars, but I definitely think you need to do yourself a favor and move away from IDLE. Anyway, I didn't mean for that to be a standalone program, but to be picked apart into chunks and dropped into an existing program (or, actually, just to be used as an example - maybe of what _not_ to do, but an example...) First error: if argv is None: argv = sys.argv == you haven't imported "sys" Second error: app = MyApp(0) == you haven't defined a class called "MyApp", so you can't do this... So I cut it down to just this bit: test = Global.cfgFile.validate(Global.vtor, copy=True) Global.cfgFile.write() (unindented all the way to the left, so that it executes as the main body of the program) and it works just fine... except: Third error (well, issue not error): Take all my comments out! They weren't meant to be included in final code. ConfigObj allows inline comments in your config file, and in the configspec - so my comments show up in there too. Here's what Initial.sen ends up looking like: mask_file_name = None gray_scale = True post_event_stack = False post_event_format = Tiff 2 show_real_time = False hourly_rate = 0 slowdown = 1 # I don't know what # this value is/does, so this is probably wrong start_time = 00:00:00 # or you could make the default None? stop_time = 00:00:00 # as a default latitude, if any... I've cut everything down; I'm attaching it as Global_Config1.py (just to avoid confusion with the earlier version). If you do actually want to use it as the basis of anything, you'll want to place the call to .validate() somewhere near the beginning of the action - remember, the call to .write() just afterward is completely optional; I had it in there for testing and have kept it in there for the same reason. Does PYTHONPATH apply in Win XP? I haven't played at the level of paths for a long time in any OS. We can worry about an install "package" later for the modules. It might be best for the users of this program. Ya know, I have no idea anymore. I thought I knew - but I just did a SET from a command prompt, and I don't have a PYTHONPATH variable. I seem to reacall something from a year or two ago... (looking now) Oh yes - there's a directory under your Python directory (Python25 in my case) called "Lib", and a folder under that called "site-packages"; any text files with the extension ".pth" will be scaned for the names of folders to add to the search path.

It adds a Comand Prompt Here item to the menu when you right-click on a folder. I remember seeing a few articles explaining how to do this yourself - but why bother? 2) Tab completion is turned on by default in Windows XP - just type the first few letters of the filename, and Windows will fill in the rest. If there are several files that start with what you typed, you might need to add a few letters to get the right one, but it still saves lots and lots of typing. It even intelligently handles long filenames with spaces in them, putting them in quotes when required. If it's turned off on your machine, you can turn it back on through TweakUI (see #1 above) under Command Prompt. So for example, you would right-click on your project folder, select Command Prompt Here, type python followed by G and a tab, then Enter. (Or maybe GL then Tab, or whatever - you get the drift.) If you want a command prompt in your desktop folder, just right-click on a folder on your desktop, select CPH, then type cd.. Much simpler than Start/Run/cmd followed by cd \Documents and Settings\username\Desktop. Copy and paste DOES work, but not with keyboard shortcuts (presumably, those are intercepted by the command prompt itself) - right-click in the command window and select Paste. -- www.fsrtechnologies.com ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

File "C:\Sandia_Meteors\New_Sentinel_Development\Sentuser_Utilities_Related\sentuser\configobj.py", line 1637, in _parse ParseError, infile, cur_index) File "C:\Sandia_Meteors\New_Sentinel_Development\Sentuser_Utilities_Related\sentuser\configobj.py", line 1748, in _handle_error raise error ParseError: Invalid line at line "1". As far as I can tell, line 1 of config.obj looks OK. It's a comment. Something is amiss. I hate to say it, but IDLE is really holding you back. It's convenient because it installs automagically with Python, but it does funky, confusing things - as in this case, where it's somehow stepped on the real error and assigned blame in the wrong place; you've already experienced its internal conflicts with Tkinter... I use wxPython for my GUI goodness, and swear by SPE (Stani's Python Editor). I don't want to re-ignite the IDE wars, but I definitely think you need to do yourself a favor and move away from IDLE. Anyway, I didn't mean for that to be a standalone program, but to be picked apart into chunks and dropped into an existing program (or, actually, just to be used as an example - maybe of what _not_ to do, but an example...) First error: if argv is None: argv = sys.argv == you haven't imported "sys" Second error: app = MyApp(0) == you haven't defined a class called "MyApp", so you can't do this... So I cut it down to just this bit: test = Global.cfgFile.validate(Global.vtor, copy=True) Global.cfgFile.write() (unindented all the way to the left, so that it executes as the main body of the program) and it works just fine... except: Third error (well, issue not error): Take all my comments out! They weren't meant to be included in final code. ConfigObj allows inline comments in your config file, and in the configspec - so my comments show up in there too. Here's what Initial.sen ends up looking like: mask_file_name = None gray_scale = True post_event_stack = False post_event_format = Tiff 2 show_real_time = False hourly_rate = 0 slowdown = 1 # I don't know what # this value is/does, so this is probably wrong start_time = 00:00:00 # or you could make the default None? stop_time = 00:00:00 # as a default latitude, if any... I've cut everything down; I'm attaching it as Global_Config1.py (just to avoid confusion with the earlier version). If you do actually want to use it as the basis of anything, you'll want to place the call to .validate() somewhere near the beginning of the action - remember, the call to .write() just afterward is completely optional; I had it in there for testing and have kept it in there for the same reason. Does PYTHONPATH apply in Win XP? I haven't played at the level of paths for a long time in any OS. We can worry about an install "package" later for the modules. It might be best for the users of this program. Ya know, I have no idea anymore. I thought I knew - but I just did a SET from a command prompt, and I don't have a PYTHONPATH variable. I seem to reacall something from a year or two ago... (looking now) Oh yes - there's a directory under your Python directory (Python25 in my case) called "Lib", and a folder under that called "site-packages"; any text files with the extension ".pth" will be scaned for the names of folders to add to the search path.

It's a very powerful module - does lots of things you don't need yet, and
maybe never will - and I agree that it could benefit from a
hit-the-ground-running guide...
Here's a quick-and-dirty; you can flesh out the details from the
documentation you downloaded. (By the way, you'll also want to use the
validate module - another 14 pages or so...)
==
* Download configobj.py and validate.py; put them somewhere in your

* Add two lines to the top of your program:
from configobj import ConfigObj
from validate import Validator
* To make working with your spec easier,
import StringIO # allows you to work with strings as if they were
files
# You could just create a spec file, and open it normally, but this
keeps everything in one place.
* Somewhere in your program, create your spec and load it. There are a
lot of ways you can do this - for me, the simple thing is to put it in a
class. I create a class called Global - it's a crutch, I know...
class Global(object):
cfgFileName = os.getcwd() + os.sep + 'Initial.sen' # current
directory + \ + filename - but you could put it anywhere and call it
anything
# create your spec as a multi-line string between triple quotes
tmpStr =
mask_file_name = string(default=None)
gray_scale = boolean(default=True)
post_event_stack = boolean(default=False)
post_event_format = string(default=Tiff 2)
show_real_time = boolean(default=False)
hourly_rate = integer(min=0, default=0)
slowdown= integer(min=0, max=10, default=1) # I don't know what
this value is/does, so this is probably wrong
start_time = string(default=00:00:00) # or you could make the
default None?
stop_time = string(default=00:00:00)
lat = float(min=0.0, max=90.0) # I have no idea what you'd want
as a default latitude, if any...
cfgSpec = StringIO.StringIO(tmpStr) # turns the above string
into a file-like object, which ConfigObj is expecting
cfgFile = ConfigObj(cfgFileName,
configspec=cfgSpec, raise_errors=True,
write_empty_values=True,
create_empty=True, indent_type='',
list_values=True) # creates the actual ConfigObj object
vtor = Validator() # creates a validator to match your config
data against your spec
* Invoke the above code when your program starts - I do it just before
my mainloop, like so:
def main(argv=None):
if argv is None:
argv = sys.argv
test = Global.cfgFile.validate(Global.vtor, copy=True) # tries
to load cfgFile; if it doesn't exist, creates it; fills in defaults for any
missing values
Global.cfgFile.write() # saves the validated file (you don't
need to do this here at the start, but I usually do)
app = MyApp(0)
app.MainLoop()
if __name__ == '__main__':
main()
* Your ConfigObj is ready to use! Simply access the contents like a
regular dictionary. To save back to the file, call the write() method.
Global.cfgFile['mask_file_name'] = 'bogus.txt'
Global.cfgFile.write()
maskFile = Global.cfgFile['mask_file_name']
* Or use the values directly without copying to intermediate variables:
with open(Global.cfgFile['mask_file_name'], 'w+b') as maskFile:
maskFile.write('some bogus text')
==
I'm attaching that as a text file too - I suspect that my indentation won't
survive the trip...
My Global class is an ugly hack. I'm sure you'll come up with something
more aesthetically pleasing...
ConfigObj has lots of very cool features - sections, repeated sections,
custom input validators - that's what the 50+ pages of documentation are
about. When you need that stuff, it's available.

OK, I got the ObjectConfig and Validate downloads, and copied your

I'm attaching that as a text file too - I suspect that my indentation
won't survive the trip...
My Global class is an ugly hack. I'm sure you'll come up with
something more aesthetically pleasing...
ConfigObj has lots of very cool features - sections, repeated sections,
custom input validators - that's what the 50+ pages of documentation
are about. When you need that stuff, it's available.

Thanks. I recall installing several libraries though, where somehow
they were packaged to automatically install when opened.
In the http://www.voidspace.org.uk/python/configobj.html
description, I do not see much of an explanations of examples of items
like, integer(min=0, default=0). It looks like they may be called
configspecs. I see this in section 5.3.2.2.
key1 = integer(0, 30, default=15)
key2 = integer(default=15)
key3 = boolean(default=True)
key4 = option('Hello', 'Goodbye', 'Not Today', default='Not Today')
but not much else. Validators? Are there others like integer, booleand
and option? Items like start_time would then be called keywords?

general idea as the DOS search path, it's a list of directories where
Python will look for modules you ask it to import.
From the docs: (http://docs.python.org/tutorial/modules.html)
The Module Search Path
When a module named spam is
imported, the interpreter searches for a file
named spam.py
in the current directory, and then in the list of
directories specified by the environment variable PYTHONPATH. This
has the same syntax as the shell variable PATH, that is, a
list of
directory names. When PYTHONPATH is not set, or when the file is
not
found there, the search continues in an installation-dependent default
path; on
Unix, this is usually .:/usr/local/lib/python.
Actually, modules are searched in the list of directories given by
the variable sys.path
which is initialized from the directory containing the input script
(or the current directory), PYTHONPATH and the installation- dependent
default. This allows Python programs that know what they're doing to
modify or
replace the module search path. Note that because the directory
containing the
script being run is on the search path, it is important that the script
not have
the same name as a standard module, or Python will attempt to load the
script as
a module when that module is imported. This will generally be an error.

The configspec (configuration specification) is that thing I put inside of
triple quotes. It's basically a template of what your config file will look
like once it has actual data in it.
In 5.3.2, the sentence The validate method uses the
validatehttp://www.voidspace.org.uk/python/validate.htmlmodule to do
the validation links to the validate.py documentation - but
you won't see that if you're reading it on paper...
Remember I said there's a bunch of stuff there you might not need just now?
A good deal of it has to do with extending ConfigObj for your own twisted,
nefarious purposes (bwahahahahaha!) - you can write your own validators for
just about any kind of values you can imagine. However, just to get
started, the built-ins are probably good (from the validate.py doc,
http://www.voidspace.org.uk/python/validate.html#the-standard-functions):
The standard functions come built-in to every Validator instance. They work
with the following basic data types :
- integer
- float
- boolean
- string
- ip_addr
plus lists of these datatypes.
Adding additional checks is done through coding simple functions.
The full set of standard checks are :
'integer':
matches integer values (including negative). Takes optional 'min' and 'max'
arguments :
integer()
integer(3, 9)# any value from 3 to 9
integer(min=0) # any positive value
integer(max=9)
'float':
matches float values Has the same parameters as the integer check.
'boolean':matches boolean values: True or False.
Acceptable string values for True are :
true, on, yes, 1
Acceptable string values for False are :
false, off, no, 0
Any other value raises an error.
'string':
matches any string. Takes optional keyword args 'min' and 'max' to specify
min and max length of string.
'ip_addr':
matches an Internet Protocol address, v.4, represented by a dotted-quad
string, i.e. '1.2.3.4'.
'list':
matches any list. Takes optional keyword args 'min', and 'max' to specify
min and max sizes of the list. The list checks always return a list.
'tuple':
matches any list. This check returns a tuple rather than a list.
'int_list':
Matches a list of integers. Takes the same arguments as list.
'float_list':
Matches a list of floats. Takes the same arguments as list.
'bool_list':
Matches a list of boolean values. Takes the same arguments as list.
'string_list':
Matches a list of strings. Takes the same arguments as list.
'ip_addr_list':
Matches a list of IP addresses. Takes the same arguments as list.
'mixed_list':
Matches a list with different types in specific positions. List size must
match the number of arguments.
Each position can be one of :
int, str, boolean, float, ip_addr
So to specify a list with two strings followed by two integers, you write
the check as :
mixed_list(str, str, int, int)
'pass':
matches everything: it never fails and the value is unchanged. It is also
the default if no check is specified.
'option':
matches any from a list of options. You specify this test with :
option('option 1', 'option 2', 'option 3')
