Topic on Extension talk:ParserFunctions

In portuguese ,and I think also in several other languages, the comma is the decimal separator and the dot is the thousand separator, but in english is the opposite. In templates that use #expr in the portuguese Wikipedia the editors fill the fields using comma as decimal separator and it frequently generate erros. How can we solve this problem?

I do have the same problem in a German Wiki

For the record, for the separators for Portuguese (pt and pt-BR) are defined on the following line of languages/messages/MessagesPt.php (resp. MessagesPt_br.php)

$separatorTransformTable = array( ',' => "\xc2\xa0", '.' => ',' );

The problem seems to be analogous to bugzilla:19412 (which is about the {{#time: ... }} parser function).

I have added $expr = str_replace( ',', '.', $expr ); to the begin of ExprParser::doExpression() and replaced line 82 in ExtParserFunctions::expr() with

$result = self::getExprParser()->doExpression( $expr );
$result = $parser->mOptions->mUserLang->formatNum( $result );
return $result;

. The first replaces all commas in a given expression with dots and the second formats the output in the user language. Is this useful for you?

I think so. Thanks for you suggestion!

I requested this on bugzilla:52426.
