I have a script with dynamic hash of hashes , and I want to print the entire hash (with all other hashes).
Itried to do it recursively by checking if the current key is a hash and if yes call the current function again with refference to the sub hash.
Most of the printing seems to be OK but in... (1 Reply)
Can Someone explain me why even using Tie::IxHash I can not get the output data in the same order that it was inserted? See code below.

Hi,
In Perl, is it possible to use a range of numbers with '..' as a key in a hash?
Something in like:
%hash = (
'768..1536' => '1G',
'1537..2560' => '2G'
);
That is, the range operation is evaluated, and all members of the range are... (3 Replies)

text::vfile::asdata
Text::vFile::asData(3pm) User Contributed Perl Documentation Text::vFile::asData(3pm)NAME
Text::vFile::asData - parse vFile formatted files into data structures
SYNOPSIS
use Text::vFile::asData;
open my $fh, "foo.ics"
or die "couldn't open ics: $!";
my $data = Text::vFile::asData->new->parse( $fh );
DESCRIPTION
Text::vFile::asData reads vFile format files, such as vCard (RFC 2426) and vCalendar (RFC 2445).
DATA STRUCTURE
A vFile contains one or more objects, delimited by BEGIN and END tags.
BEGIN:VCARD
...
END:VCARD
Objects may contain sub-objects;
BEGIN:VCALENDAR
...
BEGIN:VEVENT
...
END:VEVENT
...
ENV:VCALENDAR
Each object consists of one or more properties. Each property consists of a name, zero or more optional parameters, and then a value.
This fragment:
DTSTART;VALUE=DATE:19970317
identifies a property with the name, "DSTART", the parameter "VALUE", which has the value "DATE", and the property's value is 19970317.
Those of you with an XML bent might find this more recognisable as:
<dtstart value="date">19970317</dtstart>
The return value from the "parse()" method is a hash ref.
The top level key, "objects", refers to an array ref. Each entry in the array ref is a hash ref with two or three keys.
The value of the first key, "type", is a string corresponding to the type of the object. E.g., "VCARD", "VEVENT", and so on.
The value of the second key, "properties", is a hash ref, with property names as keys, and an array ref of those property values. It's an
array ref, because some properties may appear within an object multiple times with different values. For example;
BEGIN:VEVENT
ATTENDEE;CN="Nik Clayton":mailto:nik@FreeBSD.org
ATTENDEE;CN="Richard Clamp":mailto:richardc@unixbeard.net
...
END:VEVENT
Each entry in the array ref is a hash ref with one or two keys.
The first key, "value", corresponds to the property's value.
The second key, "param", contains a hash ref of the property's parameters. Keys in this hash ref are the parameter's name, the value is
the parameter's value. (If you enable the "preserve_params" option there is an additional key populated, called "params". It is an array
ref of hash refs, each hash ref is the parameter's name and the parameter's value - these are collected in the order they are encountered
to prevent hash collisions as seen in some vCard files) line.)
The third key in the top level "objects" hash ref is "objects". If it exists, it indicates that sub-objects were found. The value of this
key is an array ref of sub-objects, with identical keys and behaviour to that of the top level "objects" key. This recursive structure
continues, nesting as deeply as there were sub-objects in the input file.
The "bin/v2yaml" script that comes with this distribution displays the format of a vFile as YAML. "t/03usage.t" has examples of picking
out the relevant information from the data structure.

We don't do any decoding of property values, including descaping ",", we're still undecided as to whether this is a bug.
