Characters in the source string are counted: the first is index
, the last one is index
. The substring requested can be defined by these two indexes. Also, the substring can be defined by one index, and the substring length. The options are:
{{str mid|<string>|<index of first character>|<length of substring>|<index of last character>}}
It returns a part of the <string>, starting with character on position index , length <sublength>, last character returned is end index.
{{str mid|Abcdefghijklmnopqrstuvwxyz|5|3}} → efg
If parameter 2 is omitted, start is from character 1:
{{str mid|Abcdefghijklmnopqrstuvwxyz||5}} → Abcde
If parameter 3 is omitted, the whole rest of the string is returned:
{{str mid|Abcdefghijklmnopqrstuvwxyz|15}} → opqrstuvwxyz
By entering a negative value , the index is counted from the end :
{{str mid|Abcdefghijklmnopqrstuvwxyz|-7|4}} → tuvw
{{str mid|Abcdefghijklmnopqrstuvwxyz|-7}} → tuvwxyz
By using parameter |4=n
, a number, you do not ask for substring length, but the last character (as counted from the start of the input string):
{{str mid|Abcdefghijklmnopqrstuvwxyz|5||7}} → efg
In the returned substring, spaces are kept:
>{{str mid|I like this.|2|6}}< → >like<
But the input string is trimmed:
>{{str mid| I like this. |2|6}}< → >like<
When the ranges (either param2 or the substring length) is out impossible in the string, an error is returned:
{{str mid|Abcdefghijklmnopqrstuvwxyz|30}} → String Module Error: String subset index out of range
{{str mid|Abcdefghijklmnopqrstuvwxyz|0|45}} → efghijklmnopqrstuvwxyz
The error can be suppressed by using |ignore errors=true
. A blank (empty string) will be returned:
{{str mid|Abcdefghijklmnopqrstuvwxyz|0|45|ignore errors=true}} → efghijklmnopqrstuvwxyz
|no category=true
switches off category adding.
|error category=[[Category:Your category name]]
sets the category to be added when in case of an error.
Default is Category:Errors reported by Module String .
