E20:Page editing

From E20

E20wiki is a wiki, meaning anyone can edit any unprotected article and the changes are viewable immediately.

It is very easy to edit a page. Click on the Edit tab at the top of the article. You can also discuss a page on its "talk page" -- simply click the Discuss tab, and then on the new page, click the Edit tab.

Then start typing in the edit box. It is helpful if you write a short description in the edit summary box about what you changed. When finished, it is preferred if you first preview your change (click the Show preview button), and once it is satisfactory, commit the change by clicking the Save page button.

To do more advanced edits, you will need to know Wiki markup. The following article attempts to describe the most important and most commonly encountered markup, but to get a complete description, see Wikipedia:How to edit a page.

General tips

  • Use a neutral point of view (don't advocate a particular opinion, or use the wiki to advertise)
  • Where appropriate, cite your sources
  • For longer edits, use a text editor to edit and spell check, then copy and paste back to the wiki and preview before committing the change
  • Use the What links here link to make sure all articles linking to your page have in mind the content you provided
  • Search the wiki to see if there is similar content in other articles already

The wiki markup

To practice editing without fear of harming any particular page, use the sandbox. Again, for a comprehensive list of the markup and its effects, see Wikipedia:How to edit a page.

Sections, paragraphs, lists and lines

What it looks like What you type

New section

Subsection

Sub-subsection

* Start with a second-level heading (==); do not use first-level headings (=).

  • Do not skip levels (e.g., second-level followed by fourth-level).

A single newline generally has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the diff function (used internally to compare different versions of a page).

But an empty line starts a new paragraph.

  • When used in a list, a newline does affect the layout (see below).

You can break lines
without starting a new paragraph.

  • Please use this sparingly.

without starting a new paragraph.
  • Lists are easy to do:
    • Start every line with a star.
      • More stars means deeper levels.
        • A newline in a list

marks the end of a list item.

  • An empty line starts a new list. 
* Lists are easy to do:
** Start every line with a star.
*** More stars means deeper levels.

marks the end of a list item.

  • You can even do mixed lists

list of definitions

the item's definition
another item
the other item's definition
  • One item per line; a newline can appear before the colon, but using a space before the colon improves parsing. 
; Definition list : list of definitions
; item : the item's definition

A colon indents a line or paragraph.

A manual newline starts a new paragraph.

  • This is primarily for displayed material, but is also used for discussion on Talk pages.

IF a line starts with a space THEN
it will be formatted exactly
as typed;
in a fixed-width font;
lines won't wrap;
ENDIF
this is useful for:
* pasting preformatted text;
* algorithm descriptions;
* program source code;
* ASCII art;
* chemical structures;
* league tables for sports roleplaying.

* WARNING: If you make it wide, you force the whole page to be wide and hence less readable, especially for people who use lower resolutions. Never start ordinary lines with spaces.

A horizontal dividing line: this is above it

and this is below it.

  • Mainly useful for separating threads on Talk pages.
  • Also used to disambiguate within an article without creating a separate page.
