Hi Folks

Could we please install the ParserFunctions MediaWiki extension ? See - http://meta.wikimedia.org/wiki/ParserFunctions

Many thanks ATB Paul

Some results from parser function parameters:

If Tests

If tests look to be working ok.

ifeq

{{#ifeq:{{lc:AbC}}|abc|yes}}  should evaluate to 'yes'

Result = yes 

{{#ifeq:banana|abc|true|false}}  should evaluate to 'false'

Result = false 

{{#ifeq:yellow|yellow|true|false}}  should evaluate to 'true'

Result = true


ifexpr

{{#ifexpr: 10 > 9 | yes | no}}  should evaluate to 'yes'

Result = yes. 

{{#ifexpr: 9 > 10 | yes | no}}  should evaluate to 'no'

Result = no.

To Investigate

May require other template(s). Though AFAIK I don't need these.  ;-) 

{{#len:string}} for string = 123456789 should evaluate to '9'

Result = {{#len:123456789}} 

{{#pos:string|target|offset}}  should evaluate to '10'

Result = {{#pos:blah blah target in string|target|offset}}

Table Row Test

I'll need to remove my workaround attempts.
