TextFormattingFAQ (r1.2)

This topic has answers to frequently asked questions about text formatting. TextFormattingRules has more on formatting rules in general. It also has links to HTML documentation.

• Q: How do I make a separator?
• Q: How do I create a title or a heading?
• Q: Text enclosed in angle brackets like <filename> is not displayed. How can I show it as it is?
• Q: Some words (like WinAPI^?) have an unwanted question mark at the end. How can I prevent that?
• Q: How can I write fixed font text?
• Q: Text I enter gets wrapped around. How can I keep the formatting as it is?
• Q: How do I create tables?
• Q: Can I include images and pictures?
• Q: Can I write colored text?

You can make a horizontal separator by writing 4 or more dashes at the beginning of a line.

The most simple way is to enclose it in '*' Asterisk characters or '_' Underscore charcters.

This is an example header enclosed in Asterisk characters

This is an example header enclosed in Underscore characters

You could use also HTML tags for headings, e.g. <H4>This is an HTML heading</H4> will show up as:

This is an HTML heading

TWiki interprets text as HTML. The '<' and '>' characters are used to define HTML commands. Any valid text within angle brackets gets interpreted by the browser as an HTML command. Invalid text is ignored, that's why it doesn't show up.

There are two work arounds if you want to display angle brackets:

• Do an escape sequence in HTML:
  • Write < instead of <
  • Write > instead of >
  • Example: Write (a > 0) instead of (a > 0)
• Replace angle brackets with curly brackets.
  • Example: Write {is-writable} instead of <is-writable>

A question mark after a word is a link to a not yet existing topic. For example, WinAPI^? is a valid WikiTopic name in WikiNotation, but the actual topic WinAPI does not exist.

If you do not intend to create a topic for a valid TWiki topic name, you can prevent it being linked by putting an HTML tag in front of it. I usually use <NOP>. This is a non existing HTML tag, so a browser just ignores it.

• Example text:
  WinAPI as it is, <NOP>WinAPI with preceeding NOP.
• Example output:
  WinAPI^? as it is, WinAPI with preceeding NOP.

Enclose text in "=" equal signs.

• Example text:
  Proportional text, =fixed font text= , proportional again.
• Example output:
  Proportional text, fixed font text , proportional again.

Alternatively you could also use preformatted text, see next question for details.

TWiki interprets text as HTML. It is possible to use preformatted text to work around this. Use the preformatted HTML tags to keep the new line of text as it is. Do so by enclosing the text with <PRE> and </PRE> tags, e.g.

This text will keep its format as it is:
<PRE>
  Unit     Price   Qty  Cost
  -------  ------  ---  ------
  aaa       12.00    3   36.00
</PRE>

It is recommended to use preformatting for tables and source code.

There are three possibilities:

1. Use Wiki rule with "|" vertical bars.
2. Use HTML tables with <TABLE>, <TR>, <TD> tags.
3. Use preformatted text with <PRE> tags.

1. Use Wiki rule with "|" vertical bars

• Example text:
  | cell A1 | cell B1 | cell C1 |
| cell A2 | cell B2 | cell C2 |
• Example output:

  cell A1	cell B1	cell C1
  cell A2	cell B2	cell C2

2. Use HTML tables with <TABLE>, <TR>, <TD> tags

This is a manual process using HTML commands. Here is an example. If you enter this:

<TABLE BORDER=1>
  <TR>
    <TH> Head A  </TH> <TH> Head B  </TH>
  </TR><TR>
    <TD> Cell A2 </TD> <TD> Cell B2 </TD>
  </TR><TR>
    <TD> Cell A3 </TD> <TD> Cell B3 </TD>
  </TR>
</TABLE>

It is displayed as a table like this:

You can copy the example from <TABLE> to </TABLE> and change it to your needs.

More information about HTML tables can be found at http://www.htmlhelp.com/reference/wilbur/table/table.html

3. Use preformatted text with <PRE> tags

See Q: Text I enter gets wrapped around. How can I keep the formatting as it is?

Yes, this is possible. The easiest way of including images is to attach a GIF or JPG file to a topic and then to include it with text %ATTACHURL%/myImage.gif . FileAttachment has more.

There are actually two ways of including inline images.

1. Using URL ending in .gif, .jpg, .jpeg

This is a simple and automatic way of including inline images. Simply write the URL of the image file, this will create the inline image for you. Note: The images must be accessible as a URL.

• Example text:
  TWiki https://netfrag.org/twiki/pub/wikiHome.gif logo.
• Example output:
  TWiki logo.

2. Using <IMG> tag

This is a manual process where you have more control over the rendering of the image. Use the <IMG> tag of HTML to include JPEG and GIF files. Note: The display of the topic is faster if you include the WIDTH and HEIGHT parameters that have the actual image size. http://www.htmlhelp.com/reference/wilbur/special/img.html has more on inline images.

• Example text:
  TWiki <IMG SRC="../../../pub/wikiHome.gif" WIDTH=46 HEIGHT=50> logo.
• Example output:
  TWiki logo.

Place text you would like to specify a color inside <FONT COLOR="colorCode"> and </FONT> tags.

"colorCode" is the hexadecimal RGB color code. The color is composed by specifying the red, green and blue components of the color in hexadecimal notation. For example, to specify white, the red, green and blue components are 255, 255, 255, so you would use "#FFFFFF". Common color codes are:

• Example text:
  <FONT COLOR="#FF0000"> Red color </FONT> draws attention.
• Example output:
  Red color draws attention.
