Task T200704

Math-link is a template designed to implement {{math}} for links to workaround a 'bug' in TemplateStyles (phab:T200704).

Usage

edit

It is only necessary for the set of articles where all of the following are true:

  1. {{math}} would be used inside an internal link to wrap the link display text,
  2. {{math}} is used only for a part of the link display text, and
  3. The use of {{math}}, or one of the other templates using Template:Math/styles.css such as {{mvar}}, is the first use on the page.

If #1 or #3 is not true, use {{math}} instead. If #2 is not true, use {{math}} instead by wrapping the link and its expression text with the template, rather than putting the template inside the link text.

Item 1 is only an internal link. It is not an external link text and it is not an image link text.

Parameters

edit

There are two required parameters. The rest are optional and should be employed only where necessary.

|1=
|link=
Required. The link target.
|math=
Required. The first math display text.
|pre=
Optional. Display text intended to be placed before |math=.
|prespace=
Optional. Set to any value (such as |prespace=y) to add a space between the text from |pre= and |math=.
|midspace1=
Optional. Set to any value (such as |mid1space=y) to add a space between the text from |math= and |mid= or |math= and |math2=.
|mid=
Optional. Display text intended to be placed between |math= and |math2=. Will likely require the use of at least one of the |midnspace= parameters.
|midspace2=
Optional. Set to any value (such as |mid2space=y) to add a space between the text from |mid= and |math2= or |math= and |math2=.
|math2=
Optional. The second math display text.
|postspace=
Optional. Set to any value (such as |postspace=y) to add a space between the text from |mid= and |math2= or |math= and |math2=.
|post=
Optional. Display text intended to be placed after |math= (or |math2=).

Sunset

edit

This template is intended to be a "temporary" workaround until the bug is resolved, at which point it should be changed to implement {{math}} directly, with spaces where appropriate, and then substed and deleted.
