  • T198221: Support directionality for reference

PreliminariesEdit

An example with transcluded reference content,

<ref group='x' name='y'>{{Cite|foo|bar=baz}}</ref>

renders as follows. (Note the references section was autogenerated)

<p>
    <sup about="#mwt3" class="mw-ref" id="cite_ref-y_1-0" rel="dc:references" typeof="mw:Extension/ref" data-mw='{"name":"ref","body":{"id":"mw-reference-text-cite_note-y-1"},"attrs":{"group":"x","name":"y"}}'>
        <a href="./Main_Page#cite_note-y-1" style="counter-reset: mw-Ref 1;" data-mw-group="x"><span class="mw-reflink-text">[x 1]</span></a>
    </sup>
</p>


<div class="mw-references-wrap" typeof="mw:Extension/references" about="#mwt4" data-parsoid='{"group":"x","dsr":[52,52,0,0]}' data-mw='{"name":"references","attrs":{"group":"x"},"autoGenerated":true}'>
    <ol class="mw-references references" data-mw-group="x">
        <li about="#cite_note-y-1" id="cite_note-y-1">
            <a href="./Main_Page#cite_ref-y_1-0" data-mw-group="x" rel="mw:referencedBy"><span class="mw-linkback-text"></span></a>
            <span id="mw-reference-text-cite_note-y-1" class="mw-reference-text"><cite class="citation" about="#mwt2" typeof="mw:Transclusion" data-mw='{"parts":[{"template":{"target":{"wt":"Cite","href":"./Template:Cite"},"params":{"1":{"wt":"foo"},"bar":{"wt":"baz"}},"i":0}}]}'>...</cite></span>
        <li>
    </ol>
</div>

Ref and ReferencesEdit

First one <ref>One</ref>
Second one <ref>Two <p>p1</p> <p>p2</p> </ref>
Named one <ref name='three'>Three</ref>
Reused <ref name='three' />
Reused again <ref name='three' />

<references />

The HTML output for this wikitext is shown below. Parsoid provides the element id of the HTML via the data-mw.body.id property rather than copying the HTML dom in the data-mw.body.html property. But, both formats are considered valid and Parsoid accepts both formats when serializing HTML to wikitext.

If data-mw.body.id is specified, it is the client's responsibility to make sure that the element id is present in the DOM. If both data-mw.body.html and data-mw.body.id are specified, Parsoid uses the html property and ignores the id property.

        </li>
    </ol>
</div>

Auto-generated references blocksEdit

If the source wikitext had <ref> tags but no corresponding <references> tag to generate references, Parsoid auto-generates references blocks for every set of refs that need it. As of HTML version 1.2.1, for all such auto-generated reference block, the data-mw will have the autoGenerated property set to true.

Responsive wrappersEdit

In T159894, support was added for the cite extension's responsive parameter, which presents the references section as multiple columns based on the browser window size. This is achieved by wrapping the ordered list with a div. Of note, since this is part of the extension content, the transclusion annotations are placed on the wrapper.

DirectionalityEdit

A mw-cite-dir-XXX class is added to the reference list item based on the dir attribute specified on the reference definition. For example,

First one <ref dir="ltr">One</ref>

<references />

renders as,

<p>
    First one
    <sup about="#mwt2" class="mw-ref" id="cite_ref-1" rel="dc:references" typeof="mw:Extension/ref"
            data-mw='{"name":"ref","body":{"id":"mw-reference-text-cite_note-1"},"attrs":{"dir":"ltr"}}'>
        <a href="./Main_Page#cite_note-1" style="counter-reset: mw-Ref 1;"><span class="mw-reflink-text">[1]</span></a>
    </sup>
</p>

<div class="mw-references-wrap" typeof="mw:Extension/references" about="#mwt12" data-mw='{"name":"references","attrs":{}}'>
    <ol class="mw-references references">
        <li about="#cite_note-1" id="cite_note-1" class="mw-cite-dir-ltr">
            <a href="./Main_Page#cite_ref-1" rel="mw:referencedBy"><span class="mw-linkback-text"></span></a>
            <span id="mw-reference-text-cite_note-1" class="mw-reference-text">One</span>
        </li>
    </ol>
</div>

Error representationEdit

Parsoid's Cite implementation does not inline the i18n error text in the HTML. It instead annotates the erroneous <ref> with a mw:Error value in the typeof attribute and the i18n error key in the data-mw.errors property as shown in the following excerpt:

typeof="mw:Extension/ref mw:Error" data-mw='{"name":"ref","attrs":{"name":"example"},"errors":[{"key":"cite_error_ref_no_text"}]}'

Clients like VisualEditors will need to recognize these new attributes and display the actual error message in the correct language with parameters such as the name expanded in the error message text.

As part of T51538 the full suite of error conditions provided by Core Cite extension are being added to Parsoid Cite extension. Parsoid's Cite implementation will use the same mechanism for annotating the other error types.

CSS based configurationEdit

The display of footnotes, etc. are configured via CSS. This differs from the design of the legacy extension. See the announcement and task. FIXME: Say more ...
