When using the source editor with syntax highlighter on, when you have links inside a link to a file. The colouring of the square brackets ends at the square brackets for the link and not for the link to the file. If an external link is at the end of a file link (causing ]]]) at the end, the first two square brackets are coloured rather than the last two (]]] instead of ]]]). External links are also not styled when in file links. For example:
[[File:example.png|thumb|This a caption with a [[link]], okay?]] should be...
- A) [[File:example.png|thumb|This a caption with a [[link]], okay?]] (link colouring and darker background)
- B) [[File:example.png|thumb|This a caption with a [[link]], okay?]] (link colouring)
- C) [[File:example.png|thumb|This a caption with a [[link]], okay?]] (no styling / no link colouring)
[[File:example.png|thumb|This a caption with a [[link|display]], okay?]] should be...
- A) [[File:example.png|thumb|This a caption with a [[link|display]], okay?]] (link colouring and darker background)
- B) [[File:example.png|thumb|This a caption with a [[link|display]], okay?]] (link colouring)
- C) [[File:example.png|thumb|This a caption with a [[link|display]], okay?]] (no styling / no link colouring)
[[File:example.png|thumb|This a caption with a [https://en.wikipedia.org external link.]]] should be...
- A) [[File:example.png|thumb|This a caption with a [https://en.wikipedia.org external link.]]] (link colouring and darker background)
- B) [[File:example.png|thumb|This a caption with a [https://en.wikipedia.org external link.]]] (link colouring)
- C) [[File:example.png|thumb|This a caption with a [https://en.wikipedia.org external link.]]] (square bracket colouring fixed)
[[File:example.png|thumb|This a caption with a [https://en.wikipedia.org external link], okay?]] should be...
- A) [[File:example.png|thumb|This a caption with a [https://en.wikipedia.org external link], okay?]] (link colouring and darker background)
- B) [[File:example.png|thumb|This a caption with a [https://en.wikipedia.org external link], okay?]] (link colouring)
- C) Not changed
[[File:example.png|thumb|This a caption with a [https://en.wikipedia.org], okay?]] should be...
- A) [[File:example.png|thumb|This a caption with a [https://en.wikipedia.org], okay?]] (link colouring and darker background)
- B) [[File:example.png|thumb|This a caption with a [https://en.wikipedia.org], okay?]] (link colouring)
- C) Not changed
I prefer option A and I'm fine with either option B or option C. I originally posted this at Wikipedia:VisualEditor/Feedback on the English Wikipedia, but it makes more sense for it to be here.
