ފަންވަތް:Str ≠ len
This template is used on approximately 38,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
This template uses Lua: |
{{str ≠ len}} meta-template.
It helps other templates check if a string is "not equal" vs. "equal" to a given length.
Note! For most usage cases it might be better to use{{str ≥ len}}. (See the see also section below.)
Usage
[އުނިއިތުރު ގެންނަވާ]This template takes 3 to 4 unnamed parameters.
Here is how to check if the string "abcde" is exactly 5 characters:
{{str ≠ len | abcde | 5 | Not equal. | Equal. }}
Which returns this:
- Equal.
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 exactly 100 characters:
{{str ≠ len | 1 = ab=cde | 2 = 100 | 3 = Not equal, "!=". | 4 = Equal, "=". }}
Which returns this:
- Not equal, "!=".
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.
Parameters
[އުނިއިތުރު ގެންނަވާ]Detailed parameter explanation:
{{str ≠ len | 1 = A string | 2 = A length | 3 = Data to return/render when "not equally long". | 4 = Data to return/render when "equally long". }}
Empty or undefined strings are considered to be of 0 length.
Length values below 0 are considered to be 0.
Technical details
[އުނިއިތުރު ގެންނަވާ]This template would be equivalent to templates named {{str != len}} or {{str == len}}, but we can't use those template names since they don't work well in MediaWiki.
Templates have problems to handle parameter data that contains pipes "|
", unless the pipe is inside another template {{name|param1}}
or inside a piped link [[Help:Template|help]]
. Thus templates can not handle wikitables as input unless you escape them by using the {{!}} template. This makes it hard to use wikitables as parameters to templates. Instead the usual solution is to use "HTML wikimarkup" for the table code, which is more robust.
