Revision as of 16:32, 18 December 2010
The indenter Template:in5 indents text by 5 spaces or
the count specified by
parameter 1 (range: 1 to 50 spaces).
- Usage: {{in5}} <--indents by 5 spaces
- Usage: {{in5|8}} <--indents by 8 spaces
- Usage: {{in5|47}} <--indents by 47
- Usage: {{in5}} <--indents by 5 spaces
Spaces outside the double braces will add an extra space on either
side,
such as the 12 spaces inserted by: " {{in5|10}} ".
NOTE: The name "in5" was chosen because other names were debated, such as
the name "in" being redefined as 6 different uses.
Examples
The following are examples showing larger amounts of spacing:
- Example 1: xx{{in5|10}}yy{{in5|10}}zz, produces: xx yy zz
- Example 2: xx{{in5|10}}yy{{in5|15}}zz, produces: xx yy zz
- Example 3: aa{{in5|20}}bb{{in5|20}}cc, produces: aa bb cc
- Example 4: "32.0{{in5|7}}" produces: "32.0 "
The example 4 shows the ability to put trailing spaces, such as spaces after a number in a wikitable column (coded as: | 32.0{{in5}} ). Typical numbers (with "align=right"), in a table column, often appear crowded at the right-hand side, so appending "{{in5}}" can improve readability, in tables with lines between columns.
Universal template
This Template:in5 is intended as a universal template, with the same name on all Wikipedia sites. The name "in5" with the digit "5" is unlikely to conflict with other-language Wikipedias. Care must be taken not to name a universal template with a name that would be an awkward or peculiar word in the other languages. However, in some cases, a universal template might need a different name in a few conflicting languages.
Comparison with Template:spaces
There are other templates that insert spaces, although none had allowed 50 spaces. For example, the Template:spaces has had a limit of about 15 spaces (during 2009-2010):
| Example of {{spaces|10}} and... with {{spaces|14}} with {{spaces|15}} with {{spaces|25}} |
xx{{spaces|10}}yy, produces: xxTemplate:Spacesyy xxTemplate:Spacesyy xxTemplate:Spacesyy xxTemplate:Spacesyy |
| Example of {{in5|10}} and... with {{in5|14}} with {{in5|15}} with {{in5|25}} with {{in5|45}} |
xx{{in5|10}}yy, produces: xx yy xx yy xx yy xx yy xx yy |
Again, using {{in5}} reliably allows up to 50 spaces at a time.
Performance
Template {in5} generates a mix of and spaces to avoid the space compression done by the MediaWiki parser. Each   is stored inside the formatted page (such as seen by the browser option: <View><Source>). The output is optimized to be the shortest possible markup language for spaces, in a variety of different browsers.
Typically, {in5} runs much faster than Template:spaces, generating 1/3 the markup per use (as 72% less text, over 50 fewer characters each time). Also, {in5} allows 50 spaces, whereas {spaces} has been limited to 15 spaces during 2009-2010.
