Template:Doc/doc

Don't forget to purge the contents of the base page upon creating or editing this subpage.
The template {{doc}}
is designed to add a block of documentation to various pages (mainly template pages). The subpages of a certain language will be loaded into the documentation block depending on the language of the user interface. In the case of English, the documentation will be taken from the /doc
subpage. But in all other cases, the documentation will be taken from the subpage /doc/<lang code>
Tools
The main tools are located on the top right, above the documentation block:
Create
– opens the creation of the documentation page. Appears only if the documentation page does not exist.View
– opens the documentation page.Edit
– opens the editing of the documentation page.History
– opens the history of changes to the documentation page.

Also, in the upper right corner there is a button marked with an ellipsis [ … ]. It expands/collapses additional tools:
Sandbox
– opens the creation of a subpage/sandbox
and copies the code of the original page, or, if this page exists, simply opens it.Testcases
– opens the/testcases
subpage. Useful for testing a template in different situations.Subpages
– opens Special:PrefixIndex and inserts the page name to search for all subpages.Purge
– opens a window with a message about purging the page.
Language bar
On the top right, under the tools, there are flags that switch documentation to another language. Switching is implemented by inserting &uselang=<lang code>
into the page link, so if you click on another language, then along with the documentation, the interface language will change.
The language bar can be removed if you set {{{nolang}}} to 1.
If there is no documentation in a certain language, the message “The <page> documentation page does not exist” will be displayed. if {{{pagespace}}} or actual page space is “User”, then the message “The <user> did not provide information about himself on this language (<page>).” will be displayed instead.
Parameters
- {{{1}}}: parameter for switching the template assignment:
- If you need a standard documentation block, do not enter anything in this parameter.
- 0 – will display the message “This is a documentation subpage for <page>”.
- 1 – will display the message “This is the sandbox subpage for <page>”.
- 2 – will display the message “This page is not a sandbox”.
- 3 – will display the message “This is the <page> info subpage”. Useful for user subpages.
- {{{docpage}}}: the page that will be used as documentation.
- {{{content</lang code>}}}: content that will be used as documentation, instead of a separate page. When used, the main tools are hidden.
- {{{pagespace}}}: the page space is determined automatically, but you can enter your own. The text in the header depends on this parameter:
- Template → “Template Documentation”
- File → “Summary”
- User → “About”
- In all other cases it will be “Documentation”

- {{{tools}}}: controls which tool buttons should be displayed:
- 0 – no buttons.
- 1 – only buttons “Create”, “View”, “Edit” and “History”.
- In all other cases there will be all buttons
- {{{nolang}}}: removes the language bar if set to 1.
- {{{examples}}}: examples that can be copied and used on other pages go here. When used, the “Examples” button appears, on the left under the title of the documentation block.
- {{{noscroll}}}: if you are using the {{{examples}}} parameter with few examples, this setting will turn off the right extra padding (scrollbar-gutter) needed for the scrollbar.
Creating documentation

|
.To start creating documentation, click on the “Create” button on the top right. At the very beginning of the documentation, add the template {{doc}}
and enter 0 in the parameter {{{1}}}. After that, you will see a message stating that this is a documentation subpage. And so that this message does not appear in the documentation block, it should be written in this way:
<noinclude>{{doc|0}}</noinclude>
Then the text of the documentation itself is written. First there is a brief description, and then – depending on what the documentation is written for.
