An example from php markdown readme: |
|
||||
|
|
||||
. |
|
||||
*[HTML]: Hyper Text Markup Language |
|
||||
*[W3C]: World Wide Web Consortium |
|
||||
The HTML specification |
|
||||
is maintained by the W3C. |
|
||||
. |
|
||||
<p>The <abbr title="Hyper Text Markup Language">HTML</abbr> specification |
|
||||
is maintained by the <abbr title="World Wide Web Consortium">W3C</abbr>.</p> |
|
||||
. |
|
||||
|
|
||||
They can contain arbitrary markup (see pandoc implementation): |
|
||||
|
|
||||
. |
|
||||
*[`\]:`]: foo |
|
||||
\`]:\` |
|
||||
. |
|
||||
<p><abbr title="foo">`]:`</abbr></p> |
|
||||
. |
|
||||
|
|
||||
No empty abbreviations: |
|
||||
|
|
||||
. |
|
||||
*[foo]: |
|
||||
foo |
|
||||
. |
|
||||
<p>*[foo]: |
|
||||
foo</p> |
|
||||
. |
|
||||
|
|
||||
Intersecting abbreviations (first should match): |
|
||||
|
|
||||
. |
|
||||
*[Bar Foo]: 123 |
|
||||
*[Foo Bar]: 456 |
|
||||
|
|
||||
Foo Bar Foo |
|
||||
|
|
||||
Bar Foo Bar |
|
||||
. |
|
||||
<p><abbr title="456">Foo Bar</abbr> Foo</p> |
|
||||
<p><abbr title="123">Bar Foo</abbr> Bar</p> |
|
||||
. |
|
||||
|
|
||||
Don't bother with nested abbreviations (yet?): |
|
||||
|
|
||||
. |
|
||||
*[JS]: javascript |
|
||||
*[HTTP]: hyper text blah blah |
|
||||
*[JS HTTP]: is awesome |
|
||||
JS HTTP is a collection of low-level javascript HTTP-related modules |
|
||||
. |
|
||||
<p><abbr title="is awesome">JS HTTP</abbr> is a collection of low-level javascript <abbr title="hyper text blah blah">HTTP</abbr>-related modules</p> |
|
||||
. |
|
||||
|
|
||||
Mixing up abbreviations and references: |
|
||||
|
|
||||
. |
|
||||
*[foo]: 123 |
|
||||
[bar]: 456 |
|
||||
*[baz]: 789 |
|
||||
[quux]: 012 |
|
||||
and a paragraph continuation |
|
||||
|
|
||||
foo [bar] baz [quux] |
|
||||
. |
|
||||
<p>and a paragraph continuation</p> |
|
||||
<p><abbr title="123">foo</abbr> <a href="456">bar</a> <abbr title="789">baz</abbr> <a href="012">quux</a></p> |
|
||||
. |
|
||||
|
|
||||
Don't match the middle of the string: |
|
||||
|
|
||||
. |
|
||||
*[foo]: blah |
|
||||
*[bar]: blah |
|
||||
foobar |
|
||||
. |
|
||||
<p>foobar</p> |
|
||||
. |
