=head1 NAME
WebService::HabitRPG - Perl interface to the HabitRPG API
=head1 VERSION
version 0.19
=head1 SYNOPSIS
use WebService::HabitRPG;
# The API Token and User ID are obained through the
# Setting -> API link on http://habitrpg.com/
my $hrpg = WebService::HabitRPG->new(
api_token => 'your-token-goes-here',
user_id => 'your-user-id-goes-here',
tags => { work => $uuid, home => $uuid2, ... }, # optional
);
# Get everyting about the user
my $user = $hrpg->user;
# Get all tasks.
my $tasks = $hrpg->tasks;
# Get all tasks of a particular type (eg: 'daily')
my $daily = $hrpg->tasks('daily');
# Increment/decrement a task
$hrpg->up($task_id);
$hrpg->down($task_id);
# Make a new task
$hrpg->new_task(
type => 'daily',
text => 'floss teeth',
up => 1,
down => 0,
);
=head1 DESCRIPTION
Interface to API provided by L<HabitRPG|http://habitrpg.com/>.
At the time of release, the HabitRPG API is still under construction.
This module may change as a result.
Note that when data structures are returned, they are almost
always straight conversions from the JSON returned by the
HabitRPG API.
=head1 METHODS
=head2 new
my $hrpg = WebService::HabitRPG->new(
api_token => 'your-token-goes-here',
user_id => 'your-user-id-goes-here',
tags => { work => $work_uuid, home => $home_uuid, ... },
tag_prefix => '^', # Optional, defaults to '^'
);
Creates a new C<WebService::HabitRPG> object. The C<api_token> and C<user_id>
parameters are mandatory. You may also pass your own L<WWW::Mechanize>
compatible user-agent with C<agent>, and should you need it your own HabitRPG
API base URL with C<api_base> (useful for testing, or if you're running your
own server).
By default, the official API base of C<https://habitrpg.com/api/v1> is used.
The C<tags> field is optional, but if included should consist of C<tag => uuid>
pairs. When API support is added for tags, this optional will become obsolete.
I<Use of the tags feature should be considered experimental>.
=head2 user
my $user = $hrpg->user();
Returns everything from the C</user> route in the HabitRPG API.
This is practically everything about the user, their tasks, scores,
and other information.
The Perl data structure that is returned is a straight conversion
from the JSON provided by the HabitRPG API.
=head2 tasks
my $tasks = $hrpg->tasks(); # All tasks
my $habits = $hrpg->tasks('habit'); # Only habits
Return a reference to an array of tasks. With no arguments, all
tasks (habits, dailies, todos and rewards) are returned. With
an argument, only tasks of the given type are returned. The
argument must be one of C<habit>, C<daily>, C<todo> or C<reward>.
See L<WebService::HabitRPG::Task> for a complete description of
what task objects look like.
Not all tasks will have all fields. Using the L<hrpg> command-line
tool with C<hrpg dump tasks> is a convenient way to see the
data structures returned by this method.
=head2 get_task
my $task = $hrpg->get_task('6a11dd4d-c2d6-42b7-b9ff-f562d4ccce4e');
Given a task ID, returns information on that task in the same format
at L</tasks> above.
=head2 new_task
$hrpg->new_task(
type => 'daily', # Required
text => 'floss teeth', # Required
up => 1, # Suggested, defaults true
down => 0, # Suggested, defaults true
value => 0,
note => "Floss every tooth for great justice",
completed => 0,
extend => {},
);
Creates a new task. Only the C<type> and C<text> arguments are
required, all other tasks are optional. The C<up> and C<down>
options default to true (ie, tasks can be both incremented and
decremented).
The C<type> parameter must be one of: C<habit>, C<daily>,
C<todo> or C<reward>.
The C<extend> parameter consists to key/value pairs that will be
added to the JSON create packet. This should only be used if you
know what you're doing, and wish to take advantage of new or
undocumented features in the API.
Returns a task data structure of the task created, identical
to the L</tasks> method above.
Creating tasks that can be neither incremented nor decremented
is of dubious usefulness.
=head2 updown
$hrpg->updown('6a11dd4d-c2d6-42b7-b9ff-f562d4ccce4e', 'up' );
$hrpg->updown('6a11dd4d-c2d6-42b7-b9ff-f562d4ccce4e', 'down');
Moves the habit in the direction specified. Returns a data structure
of character status:
{
exp => 11,
gp => 15.5,
hp => 50,
lv => 2,
delta => 1,
}
=head2 up
$hrpg->up($task);
Convenience method. Equivalent to C<$hrpg->updown($task, 'up')>;
=head2 down
$hrpg->down($task);
Convenience method. Equivalent to C<$hrpg->updown($task, 'down')>;
=head2 _update
$hrpg->_update($task, { attr => value });
I<This method should be considered experimental.>
Updates the given task on the server (using the underlying C<PUT>
functionality in the API). Attributes are not checked for sanity,
they're just directly converted into JSON.
=head2 search_tasks
my @tasks = $hrpg->search_tasks($search_term, all => $bool);
# Eg:
my @tasks = $hrpg->search_tasks('floss');
my @tasks = $hrpg->search_tasks('git', all => 1);
Search for tasks which match the provided search term. If the
search term C<exactly> matches a task ID, then the task ID
is returned. Otherwise, returns a list of tasks which contain
the search term in their names (the C<text> field returned by the API).
This list is in the same format as the as the L</tasks> method call.
If the term begins with the tag prefix character ('^' by default),
it is considered to be a tag, and the hashless form is searched for.
For example, '^work' will result in returning all tasks which match
the tag 'work'.
If the term does not begin with a hash, then the search term is
treated in a literal, case-insensitive fashion.
If the optional C<all> parameter is set, then all tasks are
returned. Otherwise only non-completed tasks are returned.
This is useful for providing a human-friendly way to refer to
tasks. For example:
# Search for a user-provided term
my @tasks = $hrpg->search_tasks($term);
# Increment task if found
if (@tasks == 1) {
$hrpg->up($tasks[0]->id);
}
else {
say "Too few or too many tasks found.";
}
