  # See USAGE below for more details on command line options.


Zapzi is a command line tool to take articles - from files or from the
web - and create eBooks for reading later.


=over 4

=item * Can read articles from local files or via HTTP.

=item * Understands plain text, POD, HTML and Markdown format articles.

=item * HTML is converted to a more readable form (eg no menus or
footers) to make the article easier to view on an eReader.

=item * Articles can be stored in different folders to organise your reading.

=item * eBooks can be created in MOBI, EPUB or HTML format.

=item * eBooks can be automatically copied to a directory or emailed
when published.

=item * Once you publish a folder of articles to an eBook file, the
articles are archived so you can retrieve them later if needed.


=head2 SETUP

To get started, type:

  $ zapzi init

and it will create a directory (by default ~/.zapzi) to store its
database and files. You can override this directory by setting the
environment variable C<ZAPZI_DIR>.

Zapzi will then prompt for configuration options such as preferred
format for publishing eBooks. If you run this command
non-interactively it will use defaults.

To view or change these options see L<CONFIGURATION> for further


To add an article, use C<zapzi add> with a filename on your computer,
the name of a module containing POD (eg File::Basename) or an HTTP
URL. Remember to quote URLs if they include space or shell special
characters, eg

  $ zapzi add 'http://example.com/article?id=4'

Zapzi will download a copy and store it in its database. Note that if
you need to log into a site this will not work - save a copy of the
page locally using your browser and then point Zapzi at the file.


By default, Zapzi will detect the file type and if it is HTML it will
use L<HTML::ExtractMain> to strip out non-essential parts of the page
such as menus. Other formats are treated as plain text with Markdown.

You can override this by setting the C<-t> option to C<add>. For
example, if HTMLExtractMain does not correctly determine which parts
of the article are readable you can get the complete HTML text

  $ zapzi add -t HTML 'http://example.com/article?id=4'

=head2 FOLDERS

By default, Zapzi will store articles in the 'Inbox' folder. This can
be changed by using the C<-f> option, eg

  $ zapzi add -f Foo project.txt

In order to use other folders you will need to create them first using
the C<make-folder> or C<mkf> command, eg

  $ zapzi make-folder Foo

Folders can be deleted with the C<delete-folder> or C<rd> command.
Note that this will also delete all articles in the folder.

To see a summary of your folders and how many articles are in them use
the C<list-folders> or C<lsf> command.

  $ zapzi lsf

  Inbox        2
  Archive      4
  Foo          1

To see a summary of a particular folder, use C<list> or C<ls>:

  $ zapzi ls -f Foo
  Foo      1 05-Jul-2013 Project readme

Use the C<-l> option to C<ls> to get a more detailed listing.

You can delete articles with C<zapzi rm> and move articles between
folders with C<zapzi mv>, for example:

  $ zapzi rm 10                 # remove article 10 from the database
  $ zapzi mv 12 13 Foo          # move articles 12 and 13 to folder Foo


To create an eBook, run C<zapzi publish> or C<zapzi pub>. By default
this will publish articles from the Inbox folder; use the C<-f> option
to select another folder.

You can specify the format of the eBook with the C<--format> switch.
Options are:

=over 4

=item * MOBI (the default)

=item * EPUB

=item * HTML (a single HTML file containing all the articles)


You can also set the encoding with C<--encoding> but Zapzi will
normally set this correctly based on the content and publication

If everything worked OK, Zapzi will create a new eBook in the ebooks
sub-directory of your Zapzi directory, eg C<~/.zapzi/ebooks>.

If you have set distribution options, it will also run these at this
time. See the next section for more information.

When you publish a folder, the articles are moved to the Archive
folder unless you set the C<--noarchive> option.


When an eBook is published, Zapzi can run an action on the completed
file by setting distribution options. The following distribution
methods are available:

=over 4

=item * Copy - will copy the file to another directory or file

=item * Email - will email the file to a recipient

=item * Script - will run a script with the eBook as a parameter

=item * Nothing - will do no distribution (the default)


To use this at publication time, set the C<--distribute> or C<-d>
option to the publish command. Some examples:

  $ zapzi publish -d copy /path/to/directory
  $ zapzi publish -d email me@my.address.com
  $ zapzi publish -d script /home/user/bin/myscript.sh

To set this up so distribution happens every time you publish without
needing to provide the C<-d> command line option, set the
C<distribution_method> and C<distribution_destination> config
parameters. See the Configuration section below for more details.

For email distribution, the From address used will be the same as the
To address. You can override this by setting the
C<EMAIL_SENDER_TRANSPORT_from> environment variable. By default, email
will be sent via the local sendmail service on your machine; if you
want to send by SMTP set the C<EMAIL_SENDER_TRANSPORT> environment
variable to SMTP and configure the below environment variables as
appropriate. You can also set any other options documented by

=over 4

=item EMAIL_SENDER_TRANSPORT_host: the name of the host to connect to;
defaults to localhost

=item EMAIL_SENDER_TRANSPORT_ssl: if set, connect via SSL; defaults to

=item EMAIL_SENDER_TRANSPORT_port: port to connect to; defaults to 25
for non-SSL, 465 for SSL

=item EMAIL_SENDER_TRANSPORT_timeout: maximum time in secs to wait for
server; default is 120

=item EMAIL_SENDER_TRANSPORT_sasl_username: the username to use for
auth; optional

=item EMAIL_SENDER_TRANSPORT_sasl_password: the password to use for
auth; required if username is provided



Instead of publishing, if you want to see a copy of an article use
C<zapzi show> to view the article in a browser or C<zapzi export> to
send a copy of the readable article to the standard output. Both these
commands will not archive the article.

You can chain together adding and showing, eg

  $ zapzi add show README.md

will add a copy of README.md to the database and then open a browser
to show how it looks in readable format.


Bugs and requested issues can be reported at Github. Pull requests are
also very welcome; please try to follow the existing style and
organisation of the module.



=over 4

=item * Improve text extraction and formatting - complex pages may not
render correctly or may miss sections at present

=item * Support other ways to fetch articles, eg FTP or IMAP for email.

=item * Support other article formats, eg mbox/maildir.

=item * Add the ability to read sources with state, eg RSS feeds.

=item * Publish to other eBook formats such as PDF.


=head1 NAME

Zapzi comes from the Chinese word 雜誌, meaning magazine. It is
pronounced ZAAP-zi in Cantonese.


To view or change configuration variables use the C<config get> or
C<config set> commands, eg:

  $ zapzi config get                      # to see all set variables
  $ zapzi config get publish_format       # to see one variable
  $ zapzi config set publish_format EPUB  # to set a variable

The following configuration variables are available

=over 4

=item publish_format

The eBook format Zapzi will use when running the C<publish> command.
Default is MOBI; can be set to EPUB or HTML.

=item publish_encoding

The encoding used to create an eBook when running the C<publish>
command. Default is unset, which means Zapzi will choose the best
encoding for the publication format. Can be set to UTF-8 or

=item distribution_method

The method used to automatically distribute published eBook files. Can
be either 'Copy', 'Script' or 'Nothing'. Default is 'Nothing'.

=item distribution_destination

Where to distribute published eBook files. If C<distribution_method>
is set to 'Copy' then this should be a directory name. If the method
is 'Script' this should the the full path to an executable script. If
the method is 'Email' then this should be the recipient's email address.

=item deactivate_links

If set to Y, will replace links with text when using the
HTMLExtractMain transformer. Motivation for this is eReaders with
touch screens where tapping the screen will turn the page, unless
you happen to touch a link in which case it will try to follow the
link in a web browser. This can be annoying if you are offline as
it will load the browser then ask if you want to go online.
