String::Scanf can emulate sscanf() of the C library.

SYNOPSIS

use String::Scanf; # imports sscanf()

($a, $b, $c, $d) = sscanf("%d+%d %f-%s", $input);
($e, $f, $g, $h) = sscanf("%x %o %s:%3c"); # input defaults to $_

$r = String::Scanf::format_to_re($f);
or
# works only for Perl 5.005
use String::Scanf qw(); # import nothing

my $s1 = String::Scanf->new("%d+%d %f-%s");
my $s2 = String::Scanf->new("%x %o %s:%3c");

($a, $b, $c, $d) = $s1->sscanf($input);
($e, $f, $g, $h) = $s2->sscanf(); # input defaults to $_

String::Scanf supports scanning strings for data using formats similar to the libc/stdio sscanf().

The supported sscanf() formats are as follows:

%d

Decimal integer, with optional plus or minus sign.

%u

Decimal unsigned integer, with optional plus sign.

%x
Hexadecimal unsigned integer, with optional "0x" or "0x" in front.

%o

Octal unsigned integer.

%e %f %g

(The [efg] work identically.)

Decimal floating point number, with optional plus or minus sign, in any of these formats:

1
1.
1.23
.23
1e45
1.e45
1.23e45
.23e45

The exponent has an optional plus or minus sign, and the e may also be E.

The various borderline cases like Inf and Nan are not recognized.

%s

A non-whitespace string.

%c

A string of characters. An array reference is returned containing the numerical values of the characters.

%%

A literal %.

The sscanf() formats [pnSC] are not supported.

The %s and %c have an optional maximum width, e.g. %4s, in which case at most so many characters are consumed (but fewer characters are also accecpted).

The numeric formats may also have such a width but it is ignored.

The numeric formats may have [hl before the main option, e.g. %hd, but since such widths have no meaning in Perl, they are ignored.

Non-format parts of the parameter string are matched literally (e.g. : matches as :), expect that any whitespace is matched as any whitespace (e.g. matches as s+).

libopt++ is a C++ library intended to be a replacement for the venerable GNU getopt. libopt++ library supports most of getopts features (though not optional arguments or -W), but is much simpler to use and does not permute argv[].
Enhancements:
- Updated build system to fix a few minor issues.

ego file manager is a GTK+2 file manager that uses libferris for its VFS and provides evas2, GTK tree, and optional Mozilla browser views.
Enhancements:
- This release adds the ability to drop files from f-spot onto a directory to initiate a copy.

Cora is a line fitting tool designed for emission line spectra with low count numbers.

Cora is an optional Gtk graphical user interface to the 7-part cora suite, which acts as a graphical front-end to cora_fit, and significantly facilitates the use of the latter.

It is a C-written program with graphical user interface. The program can also be run in IDL.

Puppet::Log provides a log facility with an optional Tk display.
This class implements a log facility with an optional Tk display.
I
.e once the class is created, you can log messages in it, but the Tk display does no need to be created at the same time. You may invoke later only when you need it.
When the Tk display is not invoked, the log can be either printed on STDOUT or warned on STDERR (or stay hidden). But in any case, the log message will be stored in the class so that all log messages can be retrieved later by the user or by the Tk display when invoked.
Once the Tk display is invoked, it will be updated by new logs.
Constructor parameters:
- title: Title of the Tk log display (optional)
- name: Name of the log used when printing on STDOUT or STDERR (optional)
- how: Specifies what to do when a log is sent to the object (either print on STDOUT, warn on STDERR). By default the logs will not be printed or warned. (optional)
- help The argument may be a string or a sub reference. When the help menu is invoked, either the help string will be displayed in a Tk::Dialog box or the sub will be run. In this case it is the users responsability to provide a readable help from the sub. (See "help" in Tk::Multi::Manager for further details)
Puppet classes are a set of utility classes which can be used by any object. If you use directly the Puppet::*Body class, you get the plain functionnality. And if you use the Puppet::* class, you can get the same functionnality and a Tk Gui to manage it.
The basic idea is when you construct a Puppet::* object, you have all the functionnality of the object without the GUI. Then, when the need arises, you may (or the class may decide to) open the GUI of the object. On the other hand, if the need does not arise, you may create a lot of objects without cluttering your display.
