Usage[uredi kodo]

Characters in the source string are counted: the first is index ​1​, the last one is index ​length of string​. 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

Counting from the end[uredi kodo]

By entering a negative value, the index is counted from the end:

  • {{str mid|Abcdefghijklmnopqrstuvwxyz|-7|4}} → tuvw
  • {{str mid|Abcdefghijklmnopqrstuvwxyz|-7}} → tuvwxyz

Instead if substring length, use index for last character[uredi kodo]

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

Spaces are kept[uredi kodo]

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<

Error messages[uredi kodo]

When the ranges (either param2 or the substring length) is out impossible in the string, an error is returned:

  • {{str mid|Abcdefghijklmnopqrstuvwxyz|30}} → Niz Modul Napaka: 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

Napakovne kategorije[uredi kodo]

  • |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 Kategorija:Napake, ki jih javlja Modul Niz.
