HOWTO-Plugins - How to write and use Slash plugins

=head1 QUESTIONS

=head2 What is a plugin?

A plugin is an extension to the Slash system
that adds some sort of functionality to
the site. It should inherit its basic look
and feel from the currently running theme
(for example, background/foreground colors, calling
header and footer components, etc. will be handled
by the installed theme).

=head2 How do I get my plugin into the install system?

There are two ways to do this. First, you can put it in the
plugins directory with the distribution. During the install it
will be copied to the plugins directory in (by default,
F</usr/local/slash/plugins/>. The second option is to copy it in
there yourself and make sure that your library files (perl modules)
are installed. If you decide to go the first route you
may want to consider adding your libraries to the list
of plugins that get installed, in the main Slash Makefile.

=head2 What does my plugin need to make it work with the install?

If you look at the plugins that come with Slash you will find a
file called PLUGIN. This handles how the plugin installer will
see your plugin. In the file, each keyword appears on a line
by itself with a '=' seperating it and the directive. For example:

htdoc=search.pl

The following are the keywords it knows:

=over 4

=item description

What will be displayed during the install for the user,
describing what the plugin does

=item mysql_schema

Schema for MySQL

=item mysql_dump

Dump for MySQL

=item pg_schema

Schema for PostgreSQL

=item pg_dump

Dump for PostgreSQL

=item htdoc

A document to be installed in the htdocs directory for the Slash site

=item template

A template to be installed in the database

=item image

An image to be installed in the image directory

=item note

A note to show the user when the install is over.
Good place to put notes about aditional libraries
needed, or other dependencies.

=head2 How do I install a plugin once my site is installed?

Use the install-plugin tool. If run with the C<-h> option,
it will describe the tool's usage. If can list available
plugins and you can then select which plugins you want to
install (just like with install-slashsite).

=head2 Do install-plugin and install-slashsite use the same logic?

Yes, you can find it in the Slash::Install library.

=head2 I have a really cool plugin and I would like to see it added to the Slash
distribution. Will you distribute mine?

Maybe. We don't have any rules concerning this at the moment, so it will be
on a case by case basis. At some point in the future we will come up
with a much better answer.

=head1 NAME

HOWTO-Templates - How to write Slash templates

=head1 QUESTIONS

=head2 What is a template?

A template is a bit of text that is parsed by Perl, using the Template
Toolkit. Template Toolkit has support for variables, control structures,
and more. It is more easily understood and edited by non-programmers
than is Perl, and it is much safer than executing raw Perl code.

Templates are compiled into Perl functions and the resulting compiled
code is cached. Templates are fast and convenient and easy.

For more information on how templates are written, see the man pages
for Slash::Display and Template, and the Template Toolkit web page
at E<lt>URL:http://www.template-toolkit.org/E<gt>.


=head2 How do I get my template into a running site?

Use the Template Editor via the admin menu on the site, or use
template-tool on the command line. You can find out information
on it by calling it with the "-h" option.


=head2 How do I get my template installed with a plugin/theme?

For a plugin it has to be added to the PLUGIN file (see
F<HOWTO-Plugins>). For a theme it just needs to be in the templates
directory for the theme (see F<HOWTO-Themes>).


=head2 What language encoding are the templates using?

There is a language field for templates, which is, by
default, "en_US". However, it is not currently used by the
code. We have not entirely decided how to handle languages yet.

Currently, the language is based on the same method used to determine
locales on Unix: two-letter, lowercase, ISO 639 codes for language;
two-letter, uppercase, ISO 3166 codes for country; joined with an
underscore. e.g., en_US, en_CA, de_DE, zh_CN, ja_JP.


=head2 How do I generate a blank template?

Use template-tool:

template-tool -g filename


=head2 Can I set my own Template options?

You can change some of the configuration options of Template,
(PRE_CHOMP, POST_CHOMP, and CACHE_SIZE) via the vars table.
Most options cannot be changed, however, except by editing
the Slash::Display module directly.


=head2 What can I do about whitespace between template tags?

The TRIM option (which removes whitespace before and after templates)
is on by default. Many things in Slash will fail if TRIM is not true,
because it is expected that whitespace will be removed before and after
a returned template.

PRE_CHOMP and POST_CHOMP (which remove whitespace before and
after individual tags) are off by default, but may be turned on
via the template_pre_chomp and template_post_chomp entries in the vars
table. In an upcoming version of Template, there will be a third
option, other than just "on" and "off": "collapse". This will
collapse whitespace between tags down to a single space, and will
most likely be ideal for use in Slash, since runs of whitespace in HTML
is the same as a single space, in most situations.

You can enable and disable chomping of whitespace for individual
tags with "+" and "-". To enable chomping, write a tag like this:

[% num %] comment
[%- IF num != 1 ; 's' ; END %]

That will push the "s" character up against the end of "comment",
if it is printed.

If CHOMP is enabled, you can disable it in the same way, with "+"
instead of "-". See L<Template::Parser>.


=head2 I have a really cool template for a theme/plugin, and I would like
to see it added to the Slash distribution. Will you distribute mine?

Maybe. We don't have any rules concerning this at the moment, so it will be
on a case by case basis. At some point in the future we will come up
with a much better answer. If the theme or plugin is one not included with
the Slash distribution, you should contact the theme's or plugin's creator
directly.

=head1 NAME

HOWTO-Themes - How to write and use Slash themes

=head1 QUESTIONS

=head2 What is a theme?

A theme is a website design. It can have some functionality
to it (for example, the slashcode theme is a weblog). Functionality,
though, is normally split into seperate plugins.

=head2 How do I get my theme into the install system?

There are two ways to do this. First, you can put it in the
themes directory with the distribution. During the install it
will be copied to the themes directory (by default,
F</usr/local/slash/themes/>. The second option is to copy it in there
yourself. The directory layout is very important with themes.
The install expects to find a sql directory with a mysql and postgresql
directory in it. It expects a templates directory with templates in it and
finally it expects an htdocs directory. It copies files
directly from htdocs to the install's directory.
Look at the slashcode theme as an example.

=head2 What does my theme need to make it work with the install?

Just the directory structure explained above. Right now there
is no THEME file like there is a PLUGIN file for PLUGINS.
Expect this to change at some point in the future.

=head2 I have a really cool theme and I would like to see it added to the Slash
distribution. Will you distributed mine?

Maybe. We don't have any rules concerning this at the moment, so it will be
on a case by case basis. At some point in the future we will come up
with a much better answer.
