Issue 73: problem with reading from stdin http://code.google.com/p/html5lib/issues/detail?id=73
New issue report by arthurdejong:
I have tried using pisa which uses html5lib to convert a HTML document to
PDF. The HTMl content is read from stdin and passed to html5lib.
The problem is that html5lib tries to do seek() in inputstream.py on such
streams and fails. The failure of seeks seems to be silently ignored.
On Solaris 8, Python 2.4.4, html5lib-0.11.1-py2.4.egg the following shell
snippet demonstrates the problem, this works:
pisa - - < /tmp/test.html > /tmp/test2.pdf
because stdin is a file and doing seek is valid, but this fails:
cat /tmp/test.html | pisa - - > /tmp/test3.pdf
It seems to first to try to detect the encoding, seek back to the start and
parse again. Explicitly setting the encoding worked for me but won't always
be an option.
Also (for the benefit of users that happen to run in to this in combination
with pisa) pisa 3.0.22 won't work together with html5lib 0.11.1 (does with
0.10) and fails with the following error:
AttributeError: 'module' object has no attribute 'isValidEncoding'
An ugly workaround for this is to put the following in the start of the
pisa script:
import html5lib.inputstream
html5lib.inputstream.isValidEncoding = html5lib.inputstream.codecName
Thanks.
