Template:Abbr

The following documentation is located at Template:Abbr/doc. [<Edit> Template:Abbr/doc]
[⧼Purge⧽ Template:Abbr]

The {{abbr}} OEIS Wiki formatting and function template shows a tooltip with the unabbreviated text when the mouse rolls over the corresponding abbreviation; it uses the {{Abbr/list}} helper function template containing a "database" table (of abbreviations and their associated terms) to figure out the unabbreviated term, if either the first argument or the second argument is the empty string.

FEATURE: Use _base text or preferably _base text_ to automatically turn it into a wiki link, e.g. base text. (Do not use the automatic link creation feature if base_text itself contains any underscore!)

NOTE: Many web browsers (such as Firefox, Google Chrome, Internet Explorer, Opera, Safari) show tooltip text as a tooltip when the user mouse hovers over base text. However, this behavior is not guaranteed and should not be relied on.

Usage

{{abbr|unabbreviated text|abbreviation}}

where

1. First argument: The "long form" unabbreviated text (showing as tooltip), which the "short form" is an abbreviation for;
2. Second argument: The "short form" abbreviation, showing as text on the page;

or (by accessing the "database" table of abbreviations and their corresponding unabbreviated text), either with first argument explicitly set to empty string

{{abbr||abbreviation}}

or with second argument implicitly set (as default) to empty string

{{abbr|abbreviation}}

Uses the Template:Abbr/list helper function template containing a "database" table (of abbreviations and their associated terms), if {{{1|}}} or {{{2|}}} is empty string. 

FEATURE: Surround the abbreviation with underscores, e.g. _abbreviation_ to turn it into a wiki link, e.g. [[abbreviation]].
