Question

my simple test of TopicVarsPlugin is that it works a little, ie., it seems to render properly in "preview", but not in the standard view.

btw, i have the ConditionalPlugin installed as well, which is modified per Peter Thoeny's suggestion to fix multiple line support for if/else/endif (see below).

here's my page :

   * set this TopicVarsPlugin variable
      * Set SAE_LEVEL = 3

SAE_LEVEL is %SAE_LEVEL%
SAE_LEVEL is [%SAE_LEVEL%]

%IF{ %SAE_LEVEL% eq 2 }% yes 3 is equal to 2.%ELSE% no, 3 is not equal to 2. %ENDIF%

---------------------------------------------------

i get this output in "Preview Changes", which is correct :



    *  set this TopicVarsPlugin? variable
          o Set SAE_LEVEL = 3

SAE_LEVEL is 3 SAE_LEVEL is [3]

no, 3 is not equal to 2. 

------------------------------------------------

after "save changes" i get this output, which does not
properly render  :

    *  set this TopicVarsPlugin? variable
          o Set SAE_LEVEL = 3

SAE_LEVEL is 3 SAE_LEVEL is [3]

%IF{ 3 eq 2 }% yes 3 is equal to 2.%ELSE% no, 3 is not equal to 2. %ENDIF% 

----------------------------------------------------------------------------

This is the communication with Peter Thoeny regarding the ConditionalText multiple
line issue :

I have not tried out this Plugin. Looking at the
source, it is coded to work only on one line.
To span multiple lines you need to add a 's' switch
to the regex in sub commonTagsHandler. 

Change from:
    $_[0] =~ s/$prefixPattern$condPattern_ifelse.../.../geo;
    $_[0] =~ s/$prefixPattern$condPattern_ifonly.../.../geos;
To:
    $_[0] =~ s/$prefixPattern$condPattern_ifelse.../.../geos;
    $_[0] =~ s/$prefixPattern$condPattern_ifonly.../.../geos;

Regards,
Peter
