Template:Str ≤ len
Template documentation (for the above template, sometimes hidden or invisible)
- Description
- This template helps other templates check if a string is "shorter or equally long" vs. "longer" than a given length.
- Syntax
- Detailed parameter explanation:
{{str ≤ len
| 1 = A string, 0-500 characters long.
| 2 = 0 - 500
| 3 = Data to return/render when "shorter than or equally long".
| 4 = Data to return/render when "longer than".
}}
|
- Empty or undefined strings are considered to be of 0 length. Strings longer than 500 are not truncated to 500.
- Length values below 0 are considered to be 0. Length values above 500 are considered to be 500.
- Thus a string longer than 500 is always considered to be "longer", even if it is compared with the "correct" length value.
- Sample output
- This template takes 3 to 4 unnamed parameters. Here is how to check if the string "abcde" is 4 characters or less:
{{str ≤ len | abcde | 4
| Equal or shorter.
| Longer.
}}
|
- Which returns this: Longer.
- Templates have a problem to handle parameter data that contains equal signs "
=". But that is easily solved by using numbered parameters. Here we check if the string "ab=cde" is 100 characters or less:
{{str ≤ len
| 1 = ab=cde
| 2 = 100
| 3 = Equal "=" or shorter.
| 4 = Longer, not "=".
}}
|
- Which returns this: Equal "=" or shorter.
- It probably is a good habit to always use the numbered parameters, since you might not know beforehand exactly how the data will look that your template will feed to this meta-template.
