| Summary : Sort lines containing delimited fields
|
Description :
Sort::Fields provides a general purpose technique for efficiently sorting
lists of lines that contain data separated into fields.
Sort::Fields automatically imports two subroutines, \'fieldsort\' and
\'make_fieldsort\', and two variants, \'stable_fieldsort\' and
\'make_stable_fieldsort\'. \'make_fieldsort\' generates a sorting subroutine
and returns a reference to it. \'fieldsort\' is a wrapper for the
\'make_fieldsort\' subroutine.
The first argument to make_fieldsort is a delimiter string, which is used
as a regular expression argument for a \'split\' operator. The delimiter
string is optional. If it is not supplied, make_fieldsort splits each line
using \'/\\s+/\'.
The second argument is an array reference containing one or more field
specifiers. The specifiers indicate what fields in the strings will be used
to sort the data. The specifier \"1\" indicates the first field, \"2\"
indicates the second, and so on. A negative specifier like \"-2\" means to
sort on the second field in reverse (descending) order. To indicate a
numeric rather than alphabetic comparison, append \"n\" to the specifier. A
specifier of \"0\" means the entire string (\"-0\" means the entire string, in
reverse order).
The order in which the specifiers appear is the order in which they will be
used to sort the data. The primary key is first, the secondary key is
second, and so on.
\'fieldsort [1, 2], AATTdata\' is roughly equivalent to \'make_fieldsort([1,
2])->(AATTdata)\'. Avoid calling fieldsort repeatedly with the same sort
specifiers. If you need to use a particular sort more than once, it is more
efficient to call \'make_fieldsort\' once and reuse the subroutine it
returns.
\'stable_fieldsort\' and \'make_stable_fieldsort\' are like their \"unstable\"
counterparts, except that the items that compare the same are maintained in
their original order.
