NAME

Tree::Navigator - Generic navigation in various kinds of trees

SYNOPSIS

Create a file treenav.psgi like this :

  # create a navigator, then mount various kinds of nodes as shown below
  use Tree::Navigator;
  my $tn = Tree::Navigator->new;

  # example 1 : browse through the filesystem
  $tn->mount(Files => Filesys 
                   => {attributes => {label => 'My Web Files'},
                       mount_point => {root  => '/path/to/files'}});

  # example 2 : inspect tables and columns in a database
  my $dbh = DBI->connect(...);
  $tn->mount(MyDB => 'DBI' => {mount_point => {dbh => $dbh}});

  # example 3 : browse through the Win32 registry
  $tn->mount(HKCU => 'Win32::Registry' => {mount_point => {key => 'HKCU'}});

  # example 4 : browse through Perl internals
  $tn->mount(Ref => 'Perl::Ref' => {mount_point => {ref => $some_ref}});
  $tn->mount(Stack => 'Perl::StackTrace' => {mount_point => {}});
  $tn->mount(Symdump => 'Perl::Symdump' => {});

  # create the application
  my $app = $tn->to_app;

Then run the app

  plackup treenav.psgi

or mount the app in Apache

  <Location /treenav>
    SetHandler perl-script
    PerlResponseHandler Plack::Handler::Apache2
    PerlSetVar psgi_app /path/to/treenav.psgi
  </Location>

and use your favorite web browser to navigate through your data.

DESCRIPTION

Disclaimer

This distribution is still in an early stage, with incomplete documentation and tests, and an unstabilized API. Use for experiments, not yet for production code.

Introduction

This is a set of tools for navigating within various kinds of trees; a tree is just a set of nodes, where each node may have a content, may have attributes, and may have children nodes. Examples of such structures are filesystems, FTP sites, email boxes, Web sites, HTML pages, XML documents, etc.

The distribution provides

  • an abstract class for nodes, with a few concrete classes for some of the examples just mentioned above

  • a server application for exposing the tree structure to web clients or command-line clients (the present module).

  • a shell client [TODO]

  • an application that uses the Tree Navigator to navigate into the memory of a running Perl program.

Definitions

  - node
  - subnode
  - leaf
  - attribute
  - content

METHODS

TODO

DEPENDENCIES

This application uses Plack and Moose.

TODO

- check proper handling of SCRIPT_NAME - display node, show attrs & use IFRAME for content - option to toogle leaves in treeNav - export dir data as JSON/yaml - menu of actions on nodes

- Node types: - HTML viewer, build tree from H1, h2, etc. nodes; href links are leaves - Obj in memory - Process tree - LDAP - POM - Catalyst Actions - WWW mechanize - XML Schema - Smb Client, FTP, FTPS, SVN, GIT

- Shell : use Plack::Client

- Operation: - ls - cat - grep / ack - search / find (from attributes)

- fix utf8 bug in content
