INSTALLATION INSTRUCTIONS
=========================
To set up the Demo Website, install via a CPAN client (see below for standard
installation instructions) to ensure you install required prerequisites. Then
copy the directory contents under the 'vhost' directory into your web server
directory. For this example the path to these files and directories is assumed
to be '/var/www/demo'. If you wish to change this, please update the file paths
used in 'cgi-bin/pages.cgi' and 'cgi-bin/config/settings.ini'
If you use Apache, include the configuration snippet contained in the file
'vhosts.conf', in the appropriate Apache configuration file. Directions for
other web servers will be included at a later date.
Create a MySQL database called 'demo' and use the base file
'cgi-bin/db/demo-base.sql' as a starting point. If you wish to specify a fixed
user to access the database, you may wish to review the 'grant.sql' file or
amend the 'settings.ini' as appropriate.
You should now be able to start your Apache instance. Update your hosts file as
necessary to point to your new virtual host.
A more complete installation and configuration script is planned for the
future, which can also install plugins.
LABYRINTH DIRECTORY STRUCTURE
-----------------------------
./cgi-bin
/config - contains top level configuration files
/requests - contains despatch tables
/db - database dumps
/lib
/Labyrinth - Labyrinth Core modules
/Plugin - Labyrinth Plugin modules
/templates - Template Toolkit templates
./html
/cache - cache where reports are produced
/css - website CSS files
/images - website image files
/js - website JavaScript files
/tiny_mce - Tiny MCE JavaScript application files
./toolkit
As mentioned included in the package is the vhost entry from an Apache
configuration file. This file contains the rewrite rules that translate
user friendly URLs to the local CGI call. However, it is not necessary
to have rewrite rules, in the event you are unable to use them, and the
application can quite happily function with full 'cgi-bin/' type paths.
The './cgi-bin/pages.cgi' file is the core startup script, that simply
passes the settings file, and initiates Labyrinth. The 'act' CGI
parameter contains the primary action required. Throughout the duration
of a request, the current action may change several times, with each
referencing the despatch tables to load and run the correct functions
and render the correct templates. Each user has a nominated "realm",
which is the section of the site they are given access to. The realm
despatch table is used to load and run and default functions, and can
thus be used to render different skins and/or layout templates.
The CGI parameters are validated against the
'./cgi-bin/config/parserules.ini' file. The rules are built from these
entries and passed to Data::FormValidator. Each entry's fields refer
to parameter name, whether mandatory, default value, preprocessing
function, constraint function and finally the regular expression. If a
constraint is provided the regular expression is ignored. Where the
parameter name looks like ':^LISTED', this is a regular expression
match against the parameter name (where the ':' character is removed).
This enables parameters which have a changeable suffix, can apply the
same constraint or regular expression against each matching parameter's
value.
All SQL statements are called using a Phrasebook Design Pattern. As
such the './cgi-bin/config/phrasebook.ini' file contains all each
phrase and associated SQL as used within the application. To aid
readability SQL can be split onto multiple lines, using the '\'
character as the last entry on a line to continue onto the next.
Templates are built from the given layout, see the appropriate realm
entry in the despatch table, incorporating other templates as required,
including the 'content' template as specified by the last action
command. See the appropriate despatch table to reference the
appropriate content template.
Tiny MCE is used by Labyrinth where appropriate for text area input.
However, this is only activated on the pages where it is appropriate.
The set of scripts within the toolkit directory typically provide ad-
hoc or timed (e.g. via cron) functionality. The scripts are not
intended to be run via the web server, but often provide support
functionality, such as creating static pages or running periodic
cleanup tasks.
DISTRIBUTION INSTALLATION
-------------------------
The easiest way to install is via CPAN or CPANPLUS:
CPAN:
% perl -MCPAN -e shell [as root]
> install Labyrinth-Demo
> quit
CPANPLUS:
% cpanp
> i Labyrinth-Demo
> q
See your local 'perldoc CPAN' or 'perldoc CPANPLUS' for
instructions on setting up and configuring CPAN or CPANPLUS.
OBTAINING THE MODULE
--------------------
The latest release version of Labyrinth-Demo can be
downloaded from any CPAN site:
http://www.cpan.org/modules/by-authors/id/B/BA/BARBIE/
http://search.cpan.org/dist/Labyrinth-Demo/
Phrasebook is distributed as a gzipped tar archive file:
Labyrinth-Demo-<version>.tar.gz
where <version> represents the current version number, e.g. 0.01.
To install the module, unpack the distribution archive to
create an installation directory. Something like this:
tar zxf Labyrinth-Demo-0.01.tar.gz
or
gunzip Labyrinth-Demo-0.01.tar.gz
tar xf Labyrinth-Demo-0.01.tar
You can then 'cd' into the directory created,
cd Labyrinth-Demo-0.01
INSTALLING MANUALLY
-------------------
The 'make install' (done later) will install the modules and scripts on
your system. You may need administrator privileges to perform this task.
Alternately you can install the module to a local directory (see
ExtUtils::MakeMaker for full details), e.g.
% perl Makefile.PL PREFIX=/home/me/
Don't forget to update your PERL5LIB environment variable if you do
this, or add a line to your script to tell Perl where to find the files,
e.g.
use lib qw( /home/me/lib/perl5/site_perl/5.6.0 );
If you're not after a custom location, just do:
% perl Makefile.PL
If you are lacking any of the prerequisite modules, running that
program will tell you. All prerequisites are available from CPAN.
When you have them all:
% make && make test
If there are any failures, it's best if you contact me. It may help
other people who have the same problem. I don't tend to read the Perl
newsgroups or PerlMonks, so it's no use posting there.
When you report your trouble, be sure to send me the following
information;
+ result of `perl -V'
+ output from 'make test' - ideally do 'make test TEST_VERBOSE=1 >& errs'
Send those to bug-Labyrinth-Demo@rt.cpan.org and I'll
get back to you as soon as I'm able.
If it worked, then become root and type:
# make install
Congratulations. You've just installed Data::Phrasebook.
If you have a copy of cpantest installed, type:
% cpantest -g pass -nc -p `basename \`pwd\`` -auto
Or:
% cpantest -g pass -nc -p Labyrinth-Demo-0.01 -auto
That will tell both me and other potential users that the module
built correctly on your machine.
Cheers,
Barbie.
