[[:Category:Foo]] syntax

[Istador]

When using the normal link syntax for category pages inside an article [[Category:Foo]], it doesn't add a link to the text, but adds the page to the category. Therefore it's okay to not parse them as part of the text.

But there is a special special syntax with a colon in front that allows linking to category pages: [[:Category:Foo]]
It can also be piped to change the visual text on the page: [[:Category:Foo|Bar]].

https://en.wikipedia.org/wiki/Help:Category#Linking_to_category_pages

wtf_wikipedia doesn't support this syntax.

Code:

wtf('pre [[Category:Foo]] post').sentences(0).toHtml()
wtf('pre [[:Category:Foo]] post').sentences(0).toHtml()
wtf('pre [[:Category:Foo|Bar]] post').sentences(0).toHtml()

Actual result:

<span class="sentence">pre post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre post</span>

Expected result:

<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./Category:Foo">Category:Foo</a> post</span>
<span class="sentence">pre <a class="link" href="./Category:Foo">Bar</a> post</span>

ah interesting. Thanks for the heads-up @Istador . I think we should support this.

Updated code for wtf_wikipedia version 10.0.3 with wtf-plugin-html version 1.0.0:

wtf('pre [[Category:Foo]] post').sentences()[0].html()
wtf('pre [[:Category:Foo]] post').sentences()[0].html()
wtf('pre [[Category:Foo|Bar]] post').sentences()[0].html()
wtf('pre [[:Category:Foo|Bar]] post').sentences()[0].html()

Actual result:

<span class="sentence">pre post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre post</span>

Expected result:

<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./Category:Foo">Category:Foo</a> post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./Category:Foo">Bar</a> post</span>

File syntax is affected too.

wtf('pre [[File:Foo.png]] post').sentences()[0].html()
wtf('pre [[:File:Foo.png]] post').sentences()[0].html()
wtf('pre [[File:Foo.png|Bar]] post').sentences()[0].html()
wtf('pre [[:File:Foo.png|Bar]] post').sentences()[0].html()

Actual result:

<span class="sentence">pre post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre post</span>

Expected result:

<span class="sentence">pre <a class="link" href="./File:Foo.png">File:Foo.png</a> post</span>
<span class="sentence">pre <a class="link" href="./File:Foo.png">File:Foo.png</a> post</span>
<span class="sentence">pre <a class="link" href="./File:Foo.png">Bar</a> post</span>
<span class="sentence">pre <a class="link" href="./File:Foo.png">Bar</a> post</span>

---

File syntax within tables also seems broken:

wtf('{|\n|-\n|pre [[File:Foo.png]] post\n|}').tables()[0].data[0].col1.data.text
wtf('{|\n|-\n|pre [[:File:Foo.png]] post\n|}').tables()[0].data[0].col1.data.text
wtf('{|\n|-\n|pre [[File:Foo.png|Bar]] post\n|}').tables()[0].data[0].col1.data.text
wtf('{|\n|-\n|pre [[:File:Foo.png|Bar]] post\n|}').tables()[0].data[0].col1.data.text

Actual result:

"pre [[File:Foo.png]] post"
"pre [[:File:Foo.png]] post"
"pre Foo.png post"
"Bar]] post"

Expected result:

"pre File:Foo.png post"
"pre File:Foo.png post"
"pre Bar post"
"pre Bar post"

Thanks, I’ll check this out over the next few days
Cheers

hey Robin, thanks for the heads-up. bit of a rats-nest these interwiki links are. You're right - the parser changed slightly in 10.0.3

you can check the wikipedia sandbox to see how it behaves:

i think the category syntax works as we'd like it to

yeah, the file syntax must have some special check in the wp parser. I'll check it out.
thanks

[spencermountain]

oh wait, i'm wrong. You're correct.
maybe we need to rollback the interwiki change.
rats!

[spencermountain]

think I got this fixed in 10.1.0 - let me know?
thanks for your patience.
cheers

[Istador]

wtf_wikipedia version 10.1.0 with wtf-plugin-html version 1.0.0:

wtf('pre [[Category:Foo]] post').sentences()[0].html()
wtf('pre [[:Category:Foo]] post').sentences()[0].html()
wtf('pre [[Category:Foo|Bar]] post').sentences()[0].html()
wtf('pre [[:Category:Foo|Bar]] post').sentences()[0].html()
wtf('pre [[File:Foo.png]] post').sentences()[0].html()
wtf('pre [[:File:Foo.png]] post').sentences()[0].html()
wtf('pre [[File:Foo.png|Bar]] post').sentences()[0].html()
wtf('pre [[:File:Foo.png|Bar]] post').sentences()[0].html()
wtf('{|\n|-\n|pre [[File:Foo.png]] post\n|}').tables()[0].data[0].col1.data.text
wtf('{|\n|-\n|pre [[:File:Foo.png]] post\n|}').tables()[0].data[0].col1.data.text
wtf('{|\n|-\n|pre [[File:Foo.png|Bar]] post\n|}').tables()[0].data[0].col1.data.text
wtf('{|\n|-\n|pre [[:File:Foo.png|Bar]] post\n|}').tables()[0].data[0].col1.data.text

Actual result:

<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./:Category:Foo">Category:Foo</a> post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./:Category:Foo">Bar</a> post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./:File:Foo.png">File:Foo.png</a> post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./:File:Foo.png">Bar</a> post</span>
pre [[File:Foo.png]] post
pre File:Foo.png post
pre Foo.png post
pre Bar post

Expected result:

<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./Category:Foo">Category:Foo</a> post</span>
<span class="sentence">pre post</span>
<span class="sentence">pre <a class="link" href="./Category:Foo">Bar</a> post</span>
<span class="sentence">pre <a class="link" href="./File:Foo.png">File:Foo.png</a> post</span>
<span class="sentence">pre <a class="link" href="./File:Foo.png">File:Foo.png</a> post</span>
<span class="sentence">pre <a class="link" href="./File:Foo.png">Bar</a> post</span>
<span class="sentence">pre <a class="link" href="./File:Foo.png">Bar</a> post</span>
pre File:Foo.png post
pre File:Foo.png post
pre Bar post
pre Bar post

For reference the wiki preview:

Based on this wikitext:

pre [[Category:Foo]] post

pre [[:Category:Foo]] post

pre [[Category:Foo|Bar]] post

pre [[:Category:Foo|Bar]] post

pre [[File:Foo.png]] post

pre [[:File:Foo.png]] post

pre [[File:Foo.png|Bar]] post

pre [[:File:Foo.png|Bar]] post

---

The ./:Category and ./:File hrefs instead of ./Category and ./File are neglectible because wikis seem to redirect these URLs correctly to the variant without a colon. Though it would be better without to avoid a redirect.

---

I think it's subjectible what wtf_wikipedia should do with files without the colon syntax, because if these files would exist, the wiki would render them as links with an image inside and not as links with text. Though the textual representation in tables should be identical / consistent with that?
