Pithub::Base - Github v3 base class for all Pithub modules
version 0.01036
All Pithub modules inherit from Pithub::Base, even Pithub itself. So all attributes listed here can either be set in the constructor or via the setter on the objects.
If any attribute is set on a Pithub object it gets automatically set on objects that get created by a method call on the Pithub object. This is very convenient for attributes like the "token" or the "user" and "repo" attributes.
The "user" and "repo" attributes are special: They get even set on method calls that require both of them. This is to reduce verbosity, especially if you want to do a lot of things on the same repo. This also works for other objects: If you create an object of Pithub::Repos where you set the "user" and "repo" attribute in the constructor, this will also be set once you get to the Pithub::Repos::Keys object via the "keys" method.
Attributes passed along from the parent can be changed in the method call.
my $p = Pithub->new( per_page => 50 );
my $r1 = $p->repos; # $r->per_page == 50
my $r2 = $p->repos( per_page => 100 ); # $r->per_page == 100
Examples:
# just to demonstrate the "magic"
print Pithub->new( user => 'plu' )->repos->user; # plu
print Pithub::Repos->new( user => 'plu' )->keys->user; # plu
# and now some real use cases
my $p = Pithub->new( user => 'plu', repo => 'Pithub' );
my $r = $p->repos;
print $r->user; # plu
print $r->repo; # pithub
# usually you would do
print $r->get( user => 'plu', repo => 'Pithub' )->content->{html_url};
# but since user + repo has been set already
print $r->get->content->{html_url};
# of course parameters to the method take precedence
print $r->get( user => 'miyagawa', repo => 'Plack' )->content->{html_url};
# it even works on other objects
my $repo = Pithub::Repos->new( user => 'plu', repo => 'Pithub' );
print $repo->watching->list->first->{login};
Off by default.
See also: "auto_pagination" in Pithub::Result.
Defaults to <https://api.github.com>. For GitHub Enterprise, you'll likely need an URL like <https://github.yourdomain.com/api/v3/>.
Examples:
my $users = Pithub::Users->new( api_uri => 'https://api-foo.github.com' );
# ... is the same as ...
my $users = Pithub::Users->new;
$users->api_uri('https://api-foo.github.com');
If you want to use the response directly in JavaScript for example, Github supports setting a JSONP callback parameter.
See also: <http://developer.github.com/v3/#json-p-callbacks>.
Examples:
my $p = Pithub->new( jsonp_callback => 'loadGithubData' );
my $result = $p->users->get( user => 'plu' );
print $result->raw_content;
The result will look like this:
loadGithubData({
"meta": {
"status": 200,
"X-RateLimit-Limit": "5000",
"X-RateLimit-Remaining": "4661"
},
"data": {
"type": "User",
"location": "Dubai",
"url": "https://api.github.com/users/plu",
"login": "plu",
"name": "Johannes Plunien",
...
}
})
Be careful: The content method will try to decode the JSON into a Perl data structure. This is not possible if the "jsonp_callback" is set:
# calling this ...
print $result->content;
# ... will throw an exception like this ...
Runtime error: malformed JSON string, neither array, object, number, string or atom,
at character offset 0 (before "loadGithubData( ...
There are two helper methods:
has_jsonp_callback: check if the jsonp_callback attribute is set
Controls how many items are fetched per API call, aka "page". See also: <http://developer.github.com/v3/#pagination> and "auto_pagination".
To minimize the number of API calls to get a complete listing, this defaults to the maximum allowed by Github, which is currently 100. This may change in the future if Github changes their maximum.
Examples:
my $users = Pithub::Users->new( per_page => 30 );
# ... is the same as ...
my $users = Pithub::Users->new;
$users->per_page(30);
There are two helper methods:
has_per_page: check if the per_page attribute is set
This is a CodeRef and can be used to modify the HTTP::Request object on a global basis, before it's being sent to the Github API. It's useful for setting MIME types for example. See also: <http://developer.github.com/v3/mimes/>. This is the right way to go if you want to modify the HTTP request of all API calls. If you just want to change a few, consider sending the "prepare_request" parameter on any method call.
Let's use this example from the Github docs:
Html
"application/vnd.github-issue.html+json"
Return html rendered from the body's markdown. Response will include body_html.
Examples:
my $p = Pithub::Issues->new(
prepare_request => sub {
my ($request) = @_;
$request->header( Accept => 'application/vnd.github-issue.html+json' );
}
);
my $result = $p->get(
user => 'miyagawa',
repo => 'Plack',
issue_id => 209,
);
print $result->content->{body_html};
Please compare to the solution where you set the custom HTTP header on the method call, instead globally on the object:
my $p = Pithub::Issues->new;
my $result = $p->get(
user => 'miyagawa',
repo => 'Plack',
issue_id => 209,
options => {
prepare_request => sub {
my ($request) = @_;
$request->header( Accept => 'application/vnd.github-issue.html+json' );
},
}
);
print $result->content->{body_html};
This can be set as a default repo to use for API calls that require the repo parameter to be set. There are many of them and it can get kind of verbose to include the repo and the user for all of the calls, especially if you want to do many operations on the same user/repo.
Examples:
my $c = Pithub::Repos::Collaborators->new( repo => 'Pithub' );
my $result = $c->list( user => 'plu' );
There are two helper methods:
has_repo: check if the repo attribute is set
If the OAuth token is set, Pithub will sent it via an HTTP header on each API request. Currently the basic authentication method is not supported.
See also: <http://developer.github.com/v3/oauth/>
By default a LWP::UserAgent object, but it can be anything that implements the same interface.
This can be set as a default user to use for API calls that require the user parameter to be set.
Examples:
my $c = Pithub::Repos::Collaborators->new( user => 'plu' );
my $result = $c->list( repo => 'Pithub' );
There are two helper methods:
has_user: check if the user attribute is set
It might make sense to use this together with the repo attribute:
my $c = Pithub::Repos::Commits->new( user => 'plu', repo => 'Pithub' );
my $result = $c->list;
my $result = $c->list_comments;
my $result = $c->get('6b6127383666e8ecb41ec20a669e4f0552772363');
This can set utf8 flag.
Examples:
my $p = Pithub->new(utf8 => 0); # disable utf8 en/decoding
my $p = Pithub->new(utf8 => 1); # enable utf8 en/decoding (default)
This method is the central point: All Pithub are using this method for making requests to the Github. If Github adds a new API call that is not yet supported, this method can be used directly. It accepts an hash with following keys:
Usually you should not end up using this method at all. It's only available if Pithub is missing anything from the Github v3 API. Though here are some examples how to use it:
my $p = Pithub->new;
my $result = $p->request(
method => 'GET',
path => '/repos/plu/Pithub/issues',
params => {
state => 'closed',
direction => 'asc',
}
);
my $p = Pithub->new;
my $result = $p->request(
method => 'GET',
path => '/users/plu',
);
my $p = Pithub->new;
my $method = 'POST';
my $path = '/gists';
my $data = {
description => 'the description for this gist',
public => 1,
files => { 'file1.txt' => { content => 'String file content' } }
};
my $result = $p->request(
method => $method,
path => $path,
data => $data,
);
my $p = Pithub->new;
my $method = 'GET';
my $path = '/repos/miyagawa/Plack/issues/209';
my $data = undef;
my $options = {
prepare_request => sub {
my ($request) = @_;
$request->header( Accept => 'application/vnd.github-issue.html+json' );
},
};
my $result = $p->request(
method => $method,
path => $path,
data => $data,
options => $options,
);
This method always returns a Pithub::Result object.
This method checks if a token has been specified, or if not, and a request object is passed, then it looks for an Authorization header in the request.
Query the rate limit for the current object and authentication method.
