الگو:TOC link
This template create a link depending on the context of transclusion. It should be used only in a Page:*. It creates either a link to a given page number (in Page:* numbering) passed in parameter 1, or a link (parameter 3) to a subpage name (parameter 2) of a book. This template can be used also in context (... See p. 243) outside table of contents.
Example: Take the book whose title is Transactions of the Geological Society, 1st series, vol. 1 in the main space, the corresponding page names are [[Page:Transactions of the Geological Society, 1st series, vol. 1.djvu/xxxx]] where xxxx is the page number in the djvu file; these pages may have a different number on the scanned book, for instance page #203 in the djvu file may be the scan of p. 191 in the scanned book; so in order to show 191 you write this:
{{TOC link|203|On the Wrekin and on the Great Coal-field of Shropshire|191}}
- In Page:Transactions of the Geological Society, 1st series, vol. 1.djvu/425 the created link is [[Page:Transactions of the Geological Society, 1st series, vol. 1.djvu/203|191]].
- When this page is transcluded in main namespace, the created link is [[../On the Wrekin and on the Great Coal-field of Shropshire#191|191]]. (see Transactions of the Geological Society, 1st series, vol. 1/Index).
- Transclusion of a page using this template work also from an Index: page but only if the name of the index is identical to the name of the djvu file, in this case the created link is identical to #1.
- Parameter 3 is used as anchor, typically this is used in context like (see p. 123) to allow links with anchor from a book to itself.
- If you would like a link with complex formatting like italics, which cannot be used in links, the optional parameter 4 is used. Parameter 4 will function as the link text, and parameter 3 will function as the link target (i.e. parameter 3 does not have the italic text, and parameter 4 does). An example of this is here, for Chapters 4 & 16, where some words are italic.
- Note
- that the name of an index must always be the same as the name of the corresponding djvu file; a renaming will be necessary if the names are different, though this is only needed if you want to link from a transcluded Page: in an Index:
- formatting of text style, eg. small capitals, needs to wrap around the outside of the template, not be placed inside the template
Rationale
[ویرایش]- Using relative links allow to rename works without creating link through redirect, both page in main (top-level page and sub-page should be renamed as a whole) or the djvu and its subpages can be renamed without maintenance burden
- Avoiding relative link directly in Page:, which create a blue link when transclued in main but a red link in Page:
- It avoid link to Page: in main which can confuse reader if they don't understand what namespace and transclusion are.
- It allows a short way to express a link from a works to itself.
