Usage[ସମ୍ପାଦନା]

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}} → ପ୍ରକାଶନରେ ଅସୁବିଧା: ଅଜଣା ଚିହ୍ନ "୩" ।

If parameter 2 is omitted, start is from character 1:

  • {{str mid|Abcdefghijklmnopqrstuvwxyz||5}} → ପ୍ରକାଶନରେ ଅସୁବିଧା: ଅଜଣା ଚିହ୍ନ "୫" ।

If parameter 3 is omitted, the whole rest of the string is returned:

  • {{str mid|Abcdefghijklmnopqrstuvwxyz|15}} → opqrstuvwxyz

Counting from the end[ସମ୍ପାଦନା]

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

  • {{str mid|Abcdefghijklmnopqrstuvwxyz|-7|4}} → ପ୍ରକାଶନରେ ଅସୁବିଧା: ଅଜଣା ଚିହ୍ନ "୪" ।
  • {{str mid|Abcdefghijklmnopqrstuvwxyz|-7}} → tuvwxyz

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

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[ସମ୍ପାଦନା]

In the returned substring, spaces are kept:

  • >{{str mid|I like this.|2|6}}< → >ପ୍ରକାଶନରେ ଅସୁବିଧା: ଅଜଣା ଚିହ୍ନ "୬" ।<

But the input string is trimmed:

  • >{{str mid| I like this. |2|6}}< → >ପ୍ରକାଶନରେ ଅସୁବିଧା: ଅଜଣା ଚିହ୍ନ "୬" ।<

Error messages[ସମ୍ପାଦନା]

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}} → ପ୍ରକାଶନରେ ଅସୁବିଧା: ଅଜଣା ଚିହ୍ନ "୪" ।

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}} → ପ୍ରକାଶନରେ ଅସୁବିଧା: ଅଜଣା ଚିହ୍ନ "୪" ।

Error category[ସମ୍ପାଦନା]

  • |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.
