This is a documentation subpage for Template:Str left (see that page for the template itself). It contains usage information, categories and other content that is not part of the original template page. |
Usage
{{Str left{{{4}}}{{{5}}}{{{6}}}{{{7}}}{{{8}}}{{{9}}}{{{10}}}{{{11}}}...}}
Gives the <count> substring of characters from the start of the string (the substring has length <count>).
If <count> is invalid or empty, an empty string is returned. If undefined, it defaults to 1.
Limitations
- Length to 500: The maximum substring stops at 500 long, yet gives no error message. Only 500 characters can be extracted even if the <string> is longer.
- Inexpensive (uses no other templates).
Examples
- {{Str left| lorem ipsum dolor sit amet | 10 }} → lorem ipsu
- {{Str left| lorem ipsum dolor sit amet | 1 }} → l
- {{Str left| lorem ipsum dolor sit amet | 0 }} →
- {{Str left| lorem ipsum dolor sit amet | }} →
- {{Str left| lorem ipsum dolor sit amet }} → l
