Template:Str left
Usage
{{Str left|<string>|<count>}}
Gives the resultant <count> of characters creating a substring of characters from the start of the trimmed string (i.e. the substring returned will have length <count>, exclusive of leading whitespace characters, which are trimmed first before <count> is invoked).
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 | 4 }} → Lore, (note leading spaces trimmed!)
- {{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
- {{Str left| Lorem ipsum dolor sit amet | 40 }} → Lorem ipsum dolor sit ametLorem ipsum do
