DESCRIPTION

This script eases access to some comix websites by providing a unique and consistent interface through WWW::Comix. You can get the list of supported comics for the plugin you have in your system, the list of plugins themselves, and you can download strips for offline reading with a variety of options.

First of all, you can ask the list of available plugins, which will also give you the comics that each plugin supports. You can do this very easily:

   $ comix2 --plugins

Once you know, you'd better go to the site that the plugin supports, and see which comics you like. Once you know that you're interested into comic Foo bars and Baz the Great, for example, you can download strips for offline reading:

   $ comix2 "Foo bars" "Baz the Great"

Note that the quotes are needed by the shell due to the fact that the strips has a space in the name.

By default, a subdirectory named foo bar will be created, where the downloaded files will be saved. You can force the download to happen elsewhere using the --directory|-d option, anyway:

   $comix2 -d /path/to/your/foo-bars "Foo bars"

Each saved strip is associated to an opaque id that varies by plugin but that should uniquely identify each strip. Each time a strip is successfully downloaded, the id is recorded in a history file inside the directory, so that the next time that particular strip will not be downloaded again. By default, when mirroring the research for untaken strips stops after the program skips two already-downloaded strips. If you know that there's a batch of old strips that you haven't fetched yet, you can --insist. The history file is saved in the strip's directory with name comix2.history.

When downloading lots of strips, you'd like to be lean on the server, and allow for some time betweene each download. If you specify some value with --pause|-p, a random time will be waited, ranging from the number of seconds passed through the option to the double of that number. Hence, if you specify 5 seconds, the pause will be randomly distributed between 5 and 10 seconds.

Sometimes a given strip could be provided by two or more providers (i.e. plugins). Each plugin is weighted depending on the number of strips it makes available, but if you want to insist on using a given plugin you can specify it with the --plugin|-x option.

If you have some options that you'd like to reuse at each run, you could want to save them into a file. For example, if you know that a given strip should be handled by a given plugin, a configuration file is an excellent place to put your preference. Configuration files resemble Windows .ini files, where you can specify global options (inside a "no group" section, or a section named _) and feature-specific options (inside a group that is named after the strip). For example:

   pause 5

   [foo]
   plugin = bar

The names of the options are exactly the same of the command-line options, in their long format and without the leading dashes. You can either specify a full path to the configuration file:

   $ comix2 -c /path/to/config foo

or you can signal that the progam will find some configuration file inside the directory that's specific for the strip itself:

   $comix2 --own-config strip.config foo bar baz

OPTIONS

--all | -a

consider all comics instead of those given on the command line. Depending on the plugins that you have, you could reach quite a number of comics, so use this option with care (might be worth to download a sample of each comic and give it a try, anyway).

--comics | -C

get a list of all supported comics.

--comics-by-plugin

get a list of all supported comics, each with a list of plugins that support the given comic. This sublist is sorted by plugin priority, so the first plugin is the one that would be used by default.

--config | -c <filename>

specify a session-wide configuration file. See also --own-config below.

--directory | -d <path>

set the directory where the strips will be saved, instead of the default one built up from the feature's name.

--errors <n>

tolerate up to n consecutive errors, then bail out from current feature. If you set to zero, you'll disable this check (this proves useful when mirroring). Defaults to 2.

--get | --no-get

ask to download the strip. This is actually the default, so this option makes sense only in its negated form, to perform a dry run.

--help

print a somewhat more verbose help, showing usage, this description of the options and some examples from the synopsis.

--insist

normally, after finding a couple of strips that have already been taken, the quest for new strips is ended. If this option is given, the quest is ended only at the very end of the list of strips. This can prove useful when performing the initial mirror, because if some strips are skipped due to errors you wouldn't get them in the following downloads. When updating the offline reading cache, anyway, this option is only likely to make you waste band and time.

--man

print out the full documentation for the script.

--own-config | -o <filename>

signal that the configuration file (with the given filename) will be found in the directory used to download the strips. This allows you to have a different configuration file for each strip (unless you specify a directory, in which case all strips will share the same configuration file in that directory).

--plugin | -x <name>

set the plugin to use instead of the default one chosen by comix2 on the base of priority values. You shouldn't usually need it, because priorities are calculated in order to privilege providers that give access to more strips.

--plugins | -P

get the list of installed plugins.

--sample

get only a sample for the given strips. If you want to get a sample of all the comics, you can do this:

   $ comix2 --sample --all
--upto <n>

download at most n strips that aren't already in the local cache. This lets you be even more lean on the server, e.g scheduling n downloads per day (in this case you'll probably need --insist as well).

--usage

print a concise usage line and exit.

--version

print the version of the script.

DIAGNOSTICS

comix2 gives you a feedback on what's doing, and each operation is visually logged. You won't have difficulties in understanding what's going wrong: errors are clearly marked as such!

CONFIGURATION AND ENVIRONMENT

comix2 configurations can be given with either the --config|-c option or using the --own-config|-o option.

All options in the INTERFACE section can be given, even though not all of them will make sense. The configuration file follows a Windows .ini style, where you can have different configuration groups. In this case, each group is the name of a different feature. Every option outside a configuration group, or in group _, are considered global and applied to all features. Comments can be given with the usual hash symbol, and must be put in a line by themselves.

Example:

   # Overall pause
   pause 5

   [Foo bars]
   plugin = bar

   [Baz the Great]
   plugin = baz
