CSV Support for 0.11

In code above on begin missing:

from StringIO import StringIO

And finally a this moment for 0.11 and 0.12dev:

from trac.wiki.macros import WikiMacroBase
from trac.util import escape
from StringIO import StringIO
import csv

class CsvMacro(WikiMacroBase):
    """
    Display CSV data in a table. Simply copy and paste the CSV data into the macro body and hope for the best.

    Example:
    {{{
    {{{
    #!CSV
    123	123	123	123
    234	234	234	234
    }}}
    }}}
    Renders as

    || 123 || 123 || 123 || 123 ||
    || 234 || 234 || 234 || 234 ||
     """
       
    def get_macros(self):
        yield 'CSV'

    def expand_macro(self, formatter, name, txt):
        sniffer = csv.Sniffer()
        txt = txt.encode('ascii', 'replace')
        reader = csv.reader(StringIO(txt), sniffer.sniff(txt))
        formatter.out.write('<table class="wiki">\n')
        for row in reader:
            formatter.out.write('<tr>')
            for col in row:
                formatter.out.write('<td>%s</td>' % escape(col))
            formatter.out.write('</tr>\n')
        formatter.out.write('</table>\n')

Somehow I still couldn't get 0.11 to pickup the macro that I added to the plugins directory. So again I packed it as a real plugin and attached to the ticket, you can install it using:

easy_install http://trac-hacks.org/attachment/ticket/2801/CSV-0.11.zip?format=raw

As installable plugin
