Let's call it an alpha, since I'm actually trying it out at Abortion

New page

{{module rating|alpha}}
This module is supposed to take all the normal File:/Image: parameters from the call to a parent template ''(though it will might use its own args in preference for debug purposes)'' and return them back one by one for use by a template. Most important, it figures out by a process of elimination which of these is the caption.

== Usage ==
This is designed to be used with a template like [[:Template:Pseudo image]] which receives the parameters that ''used'' to go to a File: or Image: thumbnail. For example,

<nowiki>[[File:Abortionmethods.png|thumb|right|220px|Example: chart of abortion times]]</nowiki>

is replaced in the template by

<nowiki>{{Pseudo image|thumb|right|220px|link=:File:Abortionmethods.png|Example: chart of abortion times|image={{#invoke:Block diagram|main|''a bunch of stuff to draw the diagram as divs''}}}}</nowiki>

The current division of labor in the process is that the [[Template:Pseudo image]] accepts this call, and outputs the graphics, while this module is limited to sorting out the parameters. Therefore, calls to the module itself accept an extra parameter ''query=(field name)'' and return the desired field for use within the template. The field names presently supported are:

* ''thumb'' - returns the value "yes" if there a |thumb| or |thumbnail| is given.
* ''frame'' - returns "yes" if there is a |frame|
* ''px'' - returns the horizontal pixel size ### if there is a |###px| or |###x##px|
* ''xpx'' - returns the vertical pixel size ### if there is a |##x###px| or |x###px|
* ''float'' - returns ''left'', ''right'', ''center'', ''none'' if any one of these is present
* ''vertical'' - returns ''baseline'',''middle'',''sub'',''super'',''text-top'',''text-bottom'',''top'', or ''bottom'' if any of these is present
* ''caption'' - returns the first field that isn't any one of the preceding. Note: as a convenience, it also ignores blank fields and picks a later nonblank field instead, though that shouldn't happen anyway.
* If two different values are given for the same field (''Pseudo image|thumb|left|right|center|'', whichever comes later as they're listed above should dominate, but let's call it "undefined", i.e. don't do this. ;)
* Note that this module ignores fields like alt=, link= etc. for determining the caption because they are not unlabeled fields, but should actually return the values if queried anyway. But there's no obvious reason not to use those as simply <nowiki>{{{alt|}}},{{{link|}}}</nowiki> etc. without #invoking anyway.
