Installing Planet
-----------------

You'll need at least Python 2.2 installed on your system.  For extra
functionality, you may wish to install the following modules, but it's
not necessary.

	gzip	....	provides support for gzipped feeds
	mxTidy	....	will convert feed content to valid XHTML

Everything else Pythonesque Planet needs is included in the distribution.

 i.
    First you'll need to extract the files into a folder somewhere.
    I expect you've already done this, after all, you're reading this
    file.  You can place this wherever you like, ~/planet is a good
    choice, but so's anywhere else you prefer.

 ii.
    Make a copy the 'examples' subdirectory, name it whatever you feel
    like; I like to use the Planet's name (so ~/planet/debian), but
    it's really up to you.

    The example index.html is pretty plain and boring, if you're after
    less documentation and more instant gratification you may wish to
    use the files in 'fancy-examples' directory as your base instead.

    If you do this, be sure to copy the xml.tmpl files from the
    'examples' directory as well (they're good enough) and copy the
    stylesheet and images from the 'output' directory to somewhere
    your web server can get at them.

 iii.
    Edit the config.ini file in this directory to taste, it's pretty
    well documented so you shouldn't have any problems here.  Pay
    particular attention to the 'output_dir' option, which should be
    readable by your web server and especially the 'template_files'
    option where you'll want to change "examples" to wherever you just
    placed your copies.

 iv.
    Edit the various template (*.tmpl) files to taste, a complete list
    of available variables is at the bottom of this file.

 v.
    Run it: python planet.py pathto/config.ini

    You'll want to add this to cron, make sure you run it from the
    right directory.

 vi.
    Tell us about it! We'd love to link to you on planetplanet.org :-)


Template files
--------------

The template files used are given as a space separated list in the
'template_files' option in config.ini.  They are named ending in '.tmpl'
which is removed to form the name of the file placed in the output
directory.

Reading through the example templates is recommended, they're designed to
pretty much drop straight into your site with little modification
anyway.

Inside these template files, <TMPL_VAR xxx> is replaced with the content
of the 'xxx' variable.  The variables available are:

	name	....	} the value of the equivalent options
	link	....	} from the [Planet] section of your
	owner_name .	} Planet's config.ini file
	owner_email	}

	uri	....	link with the output filename appended

	date	....	                         { your date format
	date_iso ...	current date and time in { ISO date format
	date_822 ...	                         { RFC822 date format


There are also two loops, 'Items' and 'Channels'.  All of the lines of
the template and variable substitutions are available for each item or
channel.  Loops are created using <TMPL_LOOP LoopName>...</TMPL_LOOP>
and may be used as many times as you wish.

The 'Channels' loop iterates all of the channels (feeds) defined in the
configuration file, within it the following variables are available:

	name	....	value of the 'name' option in config.ini, or title
	title	....	title retreived from the channel's feed
	description	description retreived from the channel's feed
	link	....	link for the human-readable content (from the feed)
	uri	....	uri of the channel's feed itself

	Additionally the value of any other option specified in config.ini
	for the feed, or in the [DEFAULT] section, is available as a
	variable of the same name.

The 'Items' loop iterates all of the blog entries from all of the channels,
you do not place it inside a 'Channels' loop.  Within it, the following
variables are available:

	id	....	unique id for this entry (sometimes just the link)
	link	....	link to a human-readable version at the origin site

	title	....	title of the entry
	summary	....	a short "first page" summary
	content	....	the full content of the entry
	creator ....	if present, the author of this particular entry

	date	....	                              { your date format
	date_iso ...	date and time of the entry in { ISO date format
	date_822 ...                                  { RFC822 date format

	If the entry takes place on a date that has no prior entry has
	taken place on, the 'new_date' variable is set to that date.
	This allows you to break up the page by day.

	If the entry is from a different channel to the previous entry,
	or is the first entry from this channel on this day
	the 'new_channel' variable is set to the same value as the
	'channel_uri' variable.  This allows you to collate multiple
	entries from the same person under the same banner.
	
	Additionally the value of any variable that would be defined
	for the channel is available, with 'channel_' prepended to the
	name (e.g. 'channel_name' and 'channel_link').


There are also a couple of other special things you can do in a template.

 -  If you want HTML escaping applied to the value of a variable, use the
    <TMPL_VAR xxx ESCAPE="HTML"> form.

 -  If you want URI escaping applied to the value of a variable, use the
    <TMPL_VAR xxx ESCAPE="URI"> form.

 -  To only include a section of the template if the variable has a
    non-empty value, you can use <TMPL_IF xxx>....</TMPL_IF>.  e.g.

    <TMPL_IF new_date>
    <h1><TMPL_VAR new_date></h1>
    </TMPL_IF>

    You may place a <TMPL_ELSE> within this block to specify an
    alternative, or may use <TMPL_UNLESS xxx>...</TMPL_UNLESS> to
    perform the opposite.
