[Gnumed-devel] Placeholder clarifications - injectable placeholders

[Busser, Jim]

Where at

        
http://gitorious.org/gnumed/gnumed/blobs/master/gnumed/gnumed/client/wxpython/gmMacro.py

it reads

61      #=====================================================================
62      # values for the following placeholders must be injected from the 
outside before
63      # using them, in use they must conform to the "placeholder::::max 
length" syntax,
64      # as long as they resolve to None they return themselves
65      _injectable_placeholders = {
66              u'form_name_long': None,
67              u'form_name_short': None,
68              u'form_version': None

Two questions:

1) bearing in mind that, in line 63, it does *not* say

        "placeholder::::optional-maximum-length"

must the user be careful that the general case that tolerates the 'optional', 
as described at

        http://wiki.gnumed.de/bin/view/Gnumed/GmManualLettersForms#Placeholders

*** does not apply *** in the case of injectable placeholders, and that -- for 
reasons of how the coding was done -- there is no way around having to specify, 
in the case of one of the injectable placeholders:

        "placeholder::::must-specify-a-maximum length"

2) where, in line 64, it states

        "as long as they resolve to None"

does this simply reflect a convention that was settled upon, within the code to 
translate and pass back to the form instance, in the case of a no-results query 
for the placeholder in question, the text value 'None'

??
