Subscripting may also be performed on non-array values, in which
|
||||
case the subscripts specify a substring to be extracted.
|
||||
For example, if tt(FOO) is set to `tt(foobar)', then
|
||||
`tt(echo $FOO[2,5])' prints `tt(ooba)'.
|
||||
`tt(echo $FOO[2,5])' prints `tt(ooba)'. Note that
|
||||
some forms of subscripting described below perform pattern matching,
|
||||
and in that case the substring extends from the start of the match
|
||||
of the first subscript to the end of the match of the second
|
||||
subscript. For example,
|
||||
|
||||
example(string="abcdefghijklm"
|
||||
print ${string[+LPAR()r+RPAR()d?,+LPAR()r+RPAR()h?]})
|
||||
|
||||
prints `tt(defghi)'. This is an obvious generalisation of the
|
||||
rule for single-character matches.
