[Rest2web-develop] processing uservalues as a test condition in a template

[Ben <bi...@ma...>]

Hello,

First of all, thank you very much for rest2web, again and again, that's
a great piece of software for maintaining websites with ReStructuredText!

I'm afraid I've a very very silly question so I apologize in advance for
such a request, however I'm a bit stuck.

I've discovered that I actually can embedded some code in the
ReStructured Text file, for instance, this syntax is valid and does what
it has to do:

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

My ReST doc
=============

.. raw:: html

   <# print_details(default_section, page_title='', item_wrapper='<div
class="rightbox"><h2>Articles</h2><ul>%s</ul></div>',
do_description=False) #>

Some other stuff
----------------------------------

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--


However, instead of adding this code in my (numerous!) ReST files and
mix code and content, I would like to have a specific value for that
(for instance, a value such as 'localnavbar: yes' in the local pages
uservalues) and process the condition on the template side.
And I'm afraid this is a bit too audacious for me, could someone give me
a hand?

In my template, I tried:

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

if <% localnavbar %>==yes:
    print_details(default_section, page_title='', item_wrapper='<div 
    class="rightbox"><h2>Articles</h2><ul>%s</ul></div>',
   do_description=False)
else:
    print "<!-- nope -->"
#>

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

r2w complains a lot about <% localnavbar %> as an invalid syntax. I
monkey-like tried thispage['localnavbar'] etc. but without success. I
think I'm clearly missing something from:
http://www.voidspace.org.uk/python/rest2web/reference/uservalues.html
but I cand find what!

Any help would be much appreciated.
Many thanks,

  -- Ben

Hello Ben,

I think the syntax you want is something like:

<#
if ocalnavbar == 'yes':
    print_details(default_section, page_title='', item_wrapper='<div
    class="rightbox"><h2>Articles</h2><ul>%s</ul></div>',
   do_description=False)
else:
    print "<!-- nope -->"
#>

Hi, Michael,

Thank you for your email and have a good Easter holiday!
I'm afraid I tried this syntax as well, and I get an error since the
localnavbar doesn't seem to be defined [1].

This is what I've put in 2 rest files header:
    uservalues
    localnavbar: yes
    /uservalues

(to let you know, about 30 other  files don't have this value defined,
if it matters?)

and the error is:

Processing indexfile.
Guessing encoding. We guessed: UTF-8
Building stage.html
[err] Traceback (most recent call last):
[err]   File "/usr/bin/r2w", line 170, in <module>

[err]

(for your information, stage.txt does not have such a localnavbar value)

[1] yes, I've tried again and I fixed the little typo in your example
(ocalnavbar -> localnavbar).

This code is being executed for a file that doesn't have the variable 
defined - i.e. stage.txt.

Is this in your template? If so it will be executed for every file.

You could get round this by putting something like the following 
*before* the code:

try:
    localnavbar
except NameError:
    localnavbar = 'no'
