Re: [Semediawiki-user] Limiting the number of chars in a result field

[Philipp Z. <zal...@on...>]

Hi Neill,

that is possible by using the sub parser function. Simply choose a 
template as result printer for your query. Within that template then use 
the sub parser function to shorten your text.

E.g. {{#ifexpr: {{#len:{{{1|}}}}} > 300 | {{#sub:{{{1|}}}|0|300}} ... | 
{{{1|}}} }}
checks if the output parameter {{{1}}} contains more than 300 characters 
and if so cuts the rest and appends " ...".

regards,
Philipp
