Usage
{{sp}} will insert a single, regular breaking space.
This template is especially useful when using parser functions, and you need to insert a space at the beginning or end of an optional string. Any space character at these positions, inserted using the space bar, is automatically trimmed. Use this template if you want the space to appear in the output.
Parameters
There are no parameters.
Syntax
The template's syntax is
{{sp}}
Examples
In parser functions
Consider the mock template {{Linguist}}. It has a fixed string, "He speaks Greek", and an optional sub-string, "and Latin", which is included if the parameter |latin is specified. The code for the template looks like this:
He speaks Greek{{#if:{{{latin|}}}|and Latin}}.
Inserted spaces in the examples below are coloured in Firefox light blue (see the Mozilla Style guide).
Adding a space using the space bar
- 1. No additional space
If the parameter |latin is left out, i.e. the template is called with the code string {{Linguist}}, the output looks alright (see the table below).
However, if the template is called with the code string {{Linguist|latin=yes}}, and no space at all is included in the template code, the words "Greek" and "and" will be merged into "Greekand".
| Template code | "latin" invoked | Output |
|---|---|---|
He speaks Greek{{#if:{{{latin|}}}|and Latin}}. |
No | He speaks Greek. |
| Yes | He speaks Greekand Latin. |
- 2. Space inside function
Including a space inside the function will give the same output as in example 1, since (as mentioned above) all leading and trailing spaces are trimmed.
| Template code | "latin" invoked | Output |
|---|---|---|
He speaks Greek{{#if:{{{latin|}}}| and Latin}}. |
No | He speaks Greek. |
| Yes | He speaks Greekand Latin. |
- 3. Space outside function
If the space instead is placed outside the function, the template will work when including the sub-string. But, if |latin is left out, this code will output a space between the last word and the full stop.
| Template code | "latin" invoked | Output |
|---|---|---|
He speaks Greek {{#if:{{{latin|}}}|and Latin}}. |
No | He speaks Greek . |
| Yes | He speaks Greek and Latin. |
Adding a space using this template
- 4. {{sp}} inside function
Using this template to add a space before the optional string (i.e. {{sp}}and Latin), you will get the correct output both when leaving out |latin, and when it's invoked.
| Template code | "latin" invoked | Output |
|---|---|---|
He speaks Greek{{#if:{{{latin|}}}|{{sp}}and Latin}}. |
No | He speaks Greek. |
| Yes | He speaks Greek and Latin. |
