Bug ID: 52426
Summary: Make {{#expr: ... }} work with localized separators
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Keywords: i18n
Severity: normal
Priority: Unprioritized
Component: ParserFunctions
Assignee: [email protected]
Reporter: [email protected]
Classification: Unclassified
Mobile Platform: ---
As reported on
https://www.mediawiki.org/wiki/Thread:Extension_talk:ParserFunctions/Use_comma_as_decimal_separator
and
https://pt.wikipedia.org/w/index.php?oldid=36562067&uselang=en#Re:_Casas_decimais_no_ParserFunctions
a code such as {{#expr: 1,5 * 3 }} doesn't work on ptwiki:
https://pt.wikipedia.org/w/index.php?oldid=36571994&uselang=en
(Expression error: Unrecognized punctuation character ",".)
Currently, we have the following on languages/messages/MessagesPt.php:
> $separatorTransformTable = array( ',' => "\xc2\xa0", '.' => ',' );
so, the character "," should be treated as the decimal separator, and the
result should be 4.5, as if the user had used {{#expr: 1.5 * 3 }} on enwiki.
A user suggested at
https://www.mediawiki.org/wiki/Thread:Extension_talk:ParserFunctions/Use_comma_as_decimal_separator/reply_(3)
the following change:
Add
> $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.
Could something like this be changed in the extension's code, for use on
Portuguese Wikipedia?
