NAME

Tk::Browser.pm -- Perl library browser.

SYNOPSIS

# Open from a shell prompt:

# mkbrowser <module_pathname>  # Open a library file by name
# mkbrowser <package_name>     # Open package(s) matching 
                               # <package_name> (Unix specific);
# mkbrowser                    # Browse the entire library.

# Open from a Perl script:

use Tk::Browser;
use Lib::Module;

# Construct Browser object:
$b = new Browser;   

# Browse entire library:
$b -> open();       

# Browse a package by name:
$b -> open(package => IO::File);   

# Browse a package by module path name:
$b -> open(pathname =>"/usr/local/lib/perl5/5.6.0/open.pm");

DESCRIPTION

Tk::Browser.pm creates a Perl library module browser. The browser window contains a module listing at the upper left, a symbol listing at the upper right, and a text display.

If the argument to open() is a package or path name, the browser displays that package. The default is to list the first instance of each .pm and .pl file in the Perl library's @INC array of directories.

Clicking the left mouse button on a package name in the upper left-hand pane displays the package's information as described in the sections, "Package List", "Reference List", and "Text Display".

The right mouse button pops up a menu that provides options to search for text in the frame, and, in the package list, an option to open a new browser window on a selected package.

Package List

The package list in the upper left hand frame displays the name of a package if its package name or file pathname is given as an argument. Without arguments, the package list displays all of the packages in the Perl interpreter's @INC path array.

Reference List

The reference list in the upper right hand frame displays the contents of the main:: stash, the module's symbol table hash, the symbols produced by a lexical scan, or a cross reference listing, depending on the setting of options in the, "Package," menu.

Text Display

The text frame displays the module's source code, POD documentation, or class and version information depending on the settings of the, "View," menu.

If the default Perl configuration includes '.' in the @INC path array, the browser also displays modules in the current directory and its subdirectories.

The section "MENU FUNCTIONS" describes the menu bar functions.

If the entire library is scanned, the listing starts with the default class, UNIVERSAL. Selecting the main:: Symbol Table display from the View menu displays all of the symbols in the default stash, including those of the the Browser itself. In this stash also are the path names of library modules that are imported at run time.

The Modules ==> List Imports menu option opens a window that lists all symbol table imports.

The open() method's package option browses the first package which has a matching name, after locating it in the Perl library's @INC directories. The pathname argument specifies the path name of a single Perl module to browse. For example:

. . .

my $b = new Tk::Browser;

if( -e $ARGV[0] ) { # Package file name.
  $b -> open(pathname => $ARGV[0]);
} elsif( $ARGV[0] ) { # Module name
  $b -> open(package => $ARGV[0]);
} else {  # No argument: scan everything.
  $b -> open;
}

. . .

MainLoop;
