index statement

Description

index(snStore,nOffset)

The index statement gets the offset of the character from the left side of the rule at offset nOffset. The offset refers to the position, including other characters, to the any statement which has saved the offset which it found the character in. The index will output the character at that offset from the store snStore. If used carefully, the index and any combination can be very powerful. In previous versions of Keyman, the index statement was only valid in the output; it can now be used also in the context (but not the key section), as long as the source it refers to is before it.

snStore: The store to output from nOffset: The offset in the input to retrieve the any information from.

Examples

any(cons) "W" + any(key) > index(keyout,3) "w" index(cons,1)

History

As of version 6.0, the index() statement can also be used in the left-hand side of a rule.
