# Wiki:Editing

(Redirected from Help:Editing)

This page is about editing pages on this wiki in general. For editing command reference pages, also see Help:Command reference.

 TODO: Warning: explain here the use of ToDo category. (See: To-Do List)

## General

### May I edit pages without signing in?

Yes, but you are highly encouraged to sign in before contributing if possible. Even if your account has a username/nickname with no resemblance to your real name, this is still better than not signing in at all while editing.

### What commands do I use to edit this wiki?

In order of increasing generality, have a look at:

### How do I sign when posting a comment?

• You type: --~~~ (three tildes)
• Looks like: --Esteis
• You type: --~~~~ (four tildes)
• Looks like: --Esteis 16:37, 14 June 2012 (CEST)

### How do I edit the Main Page?

The Main Page is protected to avoid spammers. However, you can still edit it (let's hope for stupid spammers). Type Template:Main Page after contextgarden.net/ and edit that template.

## In-line elements

### ConTeXt commands

Use the cmd template for command names in running text:

• {{cmd|mycommand}},
• {{cmd|mycommand|parameters, text, etc.}}

That way, you get an automatic link to e.g. \startnarrower, or \startnarrower[middle].

You type You see
• {{cmd|startitemize}}
• {{cmd|startnarrower|[middle]}}
• {{cmd|startcolumns|2=[n=4]}}
• {{cmd|section|{First section}}}
Forgetting the pipe or the '2=' leads to this:
• {{cmd|startnarrower[middle]}}
• {{cmd|startcolumns|[n=4]}}
• {{cmd|section{First section}}}
• [[Command/startnarrower[middle]|\startnarrower[middle]]]
• \startcolumns
• [[Command/section{First section|\section{First section]]}

### The <cmd> tag is deprecated.

Sometimes, when editing an older page, you will see <cmd>\somecommand</cmd> on this wiki. This is an older, deprecated form, and you should turned it into {{cmd|somecommand}} wherever you see it.

### Linking to parameter description pages

In ConTeXt many key=value parameters are common across commands, so this wiki intends to have separate description pages for those parameters. Those are not linked from the text, in general, but they are linked from the syntax tables on command description pages. (Example.) The linking is achieved with {{key|alternative}}, which expands to [[Command/keyword:alternative]]. Nearly all the target pages do not exist yet, but don't let that stop you from linking to them. We'll get around to filling them in.

### Other inline code

For in-line markup of code, commands, parameters, etc. in running text use {{code|some code}}. If there are equality signs in the code, use e.g. {{code|1=some=code}}, because the wiki templating software interprets all text up to the first equality sign as a template parameter name. Please do use the code template instead of the <code> tags, as templates are much easier to change.

You type You see
In the following examples we use the
{{cmd|framed}} command with the
parameters {{code|1=background=color}}
and {{code|1=offset=1cm}}.


In the following examples we use the \framed command with the parameters background=color and offset=1cm.

Practically all of ConTeXt's source files are stored in the directory .../tex/context/base. There are two templates to link to online copies of the source files.

### Displaying ConTeXt output (and source)

This wiki allows you to type ConTeXt code to obtain a PNG of the resultant output, with extraneous whitespace cropped. This is very useful for including in-page examples. Below are two simple ones; for more, see Help:Context.

You type You see
<context>
The wiki is using ConTeXt Mark IV: \crlf
\contextversionnumber
</context>

<context source=yes text="This produces:">
The wiki still uses ConTeXt Mark IV: \crlf
\contextversionnumber
</context>

The wiki still uses ConTeXt Mark IV: \crlf
\contextversionnumber


This produces:

### Displaying a ConTeXt command syntax

If you want to show the calling convention(s) of a ConTeXt command, you can use <syntax> ... </syntax>. This is particularly useful in a "Command" page.

You type You see
<syntax>page</syntax>

 \page[...,...] [...,...] inherits from \pagebreak

### Displaying TeX or ConTeXt code alone

For displaying TeX and ConTeXt code use <texcode> ... </texcode>.

You type You see
<texcode>
\def\person#1#2{{\em #1 (#2)}}

\setupcolors [state=start]
\framed [background=color,
backgroundcolor=green,
offset=1cm ]{hello world!}
</texcode>

\def\person#1#2{{\em #1 (#2)}}

\setupcolors [state=start]
\framed [background=color,
backgroundcolor=green,
offset=1cm ]{hello world!}


### Displaying XML

For presenting XML source use <xmlcode> ... </xmlcode>.

You type You see
<xmlcode>
<?xml version="1.0"?>
<TeXML>
<env name="text">
Hello World
</env>
</TeXML>
</xmlcode>

<?xml version="1.0"?>
<TeXML>
<env name="text">
Hello World
</env>
</TeXML>


### Displaying other verbatim text

To dispay other verbatim text use <pre> ... </pre>.

You type You see
<pre>
This is some text and some code.

\unprotect
\def\!test{alfa}
\protect
</pre>

This is some text and some code.

\unprotect
\def\!test{alfa}
