Markup CGI - please test

In quiet moments I've been working on a python CGI script to do code markup. If you are interested enough to test it, here it is:
Markup CGI
Key features are:
1. User control over format and colour
2. Line numbering.
3. Cookies to remember settings.

Here's a sample:

Code:

[001] #Replace this code with your own
[002] 
[003] def Hello(name="World"):
[004]     """A simple function"""
[005]     print "Hello "+name #Classic
[006]     a =1+1
[007]     b=(6+7)-2
[008]     if a < b :
[009]         print "a=%s, b=%s"%(a,b)
[010] 
[011] Hello("you")
[012] Hello()
[013] Hello("The Universe")
[014] 
[015]

You don't have to like my colours

that's really nice but I did get this error:

Code:

KeyError	Python 2.2.3: /usr/bin/python
Fri Oct 15 10:27:32 2004

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

 /home/pharsc2/public_html/cgi-bin/syntax.py
  622                 oblock= cgi.escape(makeBlock(data),True)
  623                 #oblock=oblock%items
  624                 print html1%items,
  625                 fname = str(time.time()+random.random())
  626                 tf = file(os.sep+"tmp"+os.sep+fname,"w")
html1 = '\n <head>\n <meta http-equiv="Conten...tle>\n </head>\n <body>\n <hr>\n ', items = {'com': 'Red', 'entity': '1', 'key': 'BLACK', 'markup': 'vbmarkup', 'num': 'BLACK', 'op': 'BLACK', 'reformat': '1', 'str': 'Green'}

KeyError: res
      __doc__ = 'Mapping key not found.'
      __getitem__ = <bound method KeyError.__getitem__ of <exceptions.KeyError instance>>
      __init__ = <bound method KeyError.__init__ of <exceptions.KeyError instance>>
      __module__ = 'exceptions'
      __str__ = <bound method KeyError.__str__ of <exceptions.KeyError instance>>
      args = ('res',)

Weird, learning something about cookies - should have realised it is stateless and you can't guarantee that if one is received then they are all received.

Hopefully, now fixed with an update to a default dictionary.

Tested it with normal Python code and code copied from the shell and it works perfectly

. If you havn't posted a link to this in the tips and tricks thread do it already

.

Keep it up Paul,

Mark.

Mark,
Thanks for that

I think I'll allow a little more testing before suggesting it for everyday use tho - I just changed it so line numbers start from a more logical 1.

I haven't used cookies directly before so the bug that jimmy2k1 reported is a bit of a funny to me. I patched it by having defaults that get updated by whatever cookies are returned but I'm not happy with that. Anyone have any ideas?

I might change it so that one cookie has all settings which is probably tidier anyway.

Nice stuff

. One error I noticed was, when I enter something like this:

Code:

#!/usr/bin/env python
x = "foo" + "bar" + "baz"

the output is colourized, but the spaces between the + symbols are removed in the output.

Code:

#!/usr/bin/env python
x = "foo"+"bar"+"baz"

Also, your VBcode output has a space before the #!/usr/bin/env python line

You can fix the first example by selecting "No" in the reformat section

. Not sure about the second though.

Yep Scorp, you got bit by formatting

Reformat: No - means (hopefully) don't make any change to layout.

Reformat: Style 1 Tries to impose some PEP 8 style guidelines to the code. This means ignoring spaces/tabs and putting them back in where guidelines suggest they should go. The rules are fairly simplistic but try to make the code layout consistent. (Looks like I need to modify the comment handling slightly for when it's at the beginning of a line.) I put it in because my code gets a little sloppy after editing and I wanted something to tidy it up. 9/10 times it does okay.

Reformat Style 2 Is an alternative that some may prefer. (suck it an see)

The mark-up decisions are made by the tokenizer module so it should be compatible with IDLE and other packages that use it.
This might lead to funny colouration when marking up none-python code but seems to work for C/C++ okay as a lot of the reserved words are common.

Fixed spurious space insertion when comment was in column 0 and Style 1 is used.
