#44885 [Bgs]: grouped optional args is no longer supported

ID: 44885 Updated by: rquadling@php.net Reported By: colder@php.net Status: Bogus Bug Type: Doc Build problem Operating System: Irrelevant PHP Version: Irrelevant New Comment: Docbook doesn't have a methodparamgroup like tag (made up name). If it did and the group could be marked choice="opt" and could be nested, then this would work be used. Another option is to not render the ] as part of the <methodparam> tag. Instead, accumulate a count for the <methodsynopsis> and render all the ] at the close of </methodsynopsis> That way every choice="opt" would act as another level of option-ness. Currently though, as Hannes says, 2 methodsynopsis is the route being used.

This was an error in the XSL which was fixed in PhD. The markup for rand() is simply wrong. This function can be used in two different ways, either by passing no parameters or two. The correct way to do this is having two methodsynopsis, one that takes no arguments and another one that takes two (requiered) arguments. -Hannes ------------------------------------------------------------------------ [2008-05-01 23:54:59] philip@php.net The trouble with that is this: int rand ([ int $min [, int $max ]] ) versus this: int rand ([ int $min , int $max ] ) and rand() follows the latter because it requires either 0 or 2 arguments and not 1. PhD creates the first if choice="opt" is used twice. So basically we need a syntax for each and it appears both our dsssl and xsl based build systems treated this differently. The BC approach would add the following to PhD: if (only the first arg is optional) { make them all optional together; } But it's a strange syntax and ideally we'd come up with some better markup. ------------------------------------------------------------------------ [2008-05-01 23:54:21] colder@php.net Well no, that will make it rand([min[, max]]), which is also wrong, it's rand([min, max]) as in either the two or none. ------------------------------------------------------------------------ [2008-05-01 23:53:13] colder@php.net title made no sense ------------------------------------------------------------------------ [2008-05-01 23:27:17] cellog@php.net correct is: <methodparam choice="opt"><type>int</type><parameter>min</parameter></methodparam> <methodparam choice="opt"><type>int</type><parameter>max</parameter></methodparam> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
