Hello,
I have a header which I have to add to a sorted file, however if I use
cat header sortedfile > newfile, the operation takes 2 minutes as the sorted file is over 400mb.
I have noticed that when I sort the 400mb unsorted file, this only takes 14 seconds to create the output.

So, I have a file that has some duplicate lines. The file has a header line that I would like to keep at the top.
I could do this by extracting the header from the file, 'sort -u' the remaining lines, and recombine them. But they are quite big, so if there is a way to do it with a single... (1 Reply)

prima::detailedlist
Prima::DetailedList(3) User Contributed Perl Documentation Prima::DetailedList(3)NAME
Prima::DetailedList - a multi-column list viewer with controlling header widget.
SYNOPSIS
use Prima::DetailedList;
my $l = $w-> insert( 'Prima::DetailedList',
columns => 2,
headers => [ 'Column 1', 'Column 2' ],
items => [
['Row 1, Col 1', 'Row 1, Col 2'],
['Row 2, Col 1', 'Row 2, Col 2']
],
);
$l-> sort(1);
DESCRIPTION
Prima::DetailedList is a descendant of Prima::ListViewer, and as such provides a certain level of abstraction. It overloads format of items
in order to support multi-column ( 2D ) cell span. It also inserts Prima::Header widget on top of the list, so the user can interactively
move, resize and sort the content of the list. The sorting mechanism is realized inside the package; it is activated by the mouse click on
a header tab.
Since the class inherits Prima::ListViewer, some functionality, like 'item search by key', or "get_item_text" method can not operate on 2D
lists. Therefore, mainColumn property is introduced, that selects the column representing all the data.
API
Events
Sort COLUMN, DIRECTION
Called inside sort method, to facilitate custom algorithms of sorting. If the callback procedure is willing to sort by COLUMN index,
then it must call "clear_event", to signal the event flow stop. The DIRECTION is a boolean flag, specifying whether the sorting must be
performed is ascending ( 1 ) or descending ( 0 ) order.
The callback procedure must operate on the internal storage of "{items}", which is an array of arrays of scalars.
The default action is the literal sorting algorithm, where precedence is arbitrated by "cmp" operator ( see "Equality Operators" in
perlop ) .
Properties
columns INTEGER
Governs the number of columns in items. If set-called, and the new number is different from the old number, both items and headers are
restructured.
Default value: 0
headerClass
Assigns a header class.
Create-only property.
Default value: "Prima::Header"
headerProfile HASH
Assigns hash of properties, passed to the header widget during the creation.
Create-only property.
headerDelegations ARRAY
Assigns a header widget list of delegated notifications.
Create-only property.
headers ARRAY
Array of strings, passed to the header widget as column titles.
items ARRAY
Array of arrays of scalars, of arbitrary kind. The default behavior, however, assumes that the scalars are strings. The data direction
is from left to right and from top to bottom.
mainColumn INTEGER
Selects the column, responsible for representation of all the data. As the user clicks the header tab, "mainColumn" is automatically
changed to the corresponding column.
Default value: 0
Methods
sort [ COLUMN ]
Sorts items by the COLUMN index in ascending order. If COLUMN is not specified, sorts by the last specified column, or by #0 if it is
the first "sort" invocation.
If COLUMN was specified, and the last specified column equals to COLUMN, the sort direction is reversed.
The method does not perform sorting itself, but invokes Sort notification, so the sorting algorithms can be overloaded, or be applied
differently to the columns.
