mako strips first line in templates if it starts with single #

[xrot...@googlemail.com]

Hi group,
I think I found a bug in mako (just confirmed with mako 0.8 as well):
When the first line in a template starts with '#' (not '##'!), the line will be stripped from the rendered output (see below).
I encountered this behaviour when trying to add a
# coding=utf8
line to script.py.mako in an alembic configuration.

Python 2.7.3 (default, Aug  1 2012, 05:14:39)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from mako.template import Template
>>> t = Template('# coding=utf8\n"""\nstuff\n"""')
>>> t.render()
u'"""\nstuff\n"""'
>>> t = Template('\n# coding=utf8\n"""\nstuff\n"""')
>>> t.render()
u'\n# coding=utf8\n"""\nstuff\n"""'

best
robert

yeah that's actually by design, we support being able to put the "## coding" directive directly in a template to specify the template's encoding, but as you note, it does it for "#" as well - which is because in the early days, we used "#" for comments, not "##", and in the case of the coding directive we left the old behavior in place.

Anyway, you can always subvert mako's lexer using the <%text> tag:

"""<%text># coding: utf-8</%text>

stuff
