27 CPANPLUS::Dist::Base functions as a base class for all custom
28 distribution implementations. It does all the mundane work CPANPLUS
29 would have done without a custom distribution, so you can override just
30 the parts you need to make your own implementation work.
31
33 Below is a brief outline when and in which order methods in this class
34 are called:
35 $Class->format_available; # can we use this class on this system?
37 $dist->init; # set up custom accessors, etc
39 $dist->prepare; # find/write meta information
40 $dist->create; # write the distribution file
41 $dist->install; # install the distribution file
42 $dist->uninstall; # remove the distribution (OPTIONAL)
44
46 @subs = $Class->methods
47 Returns a list of methods that this class implements that you can
48 override.
49 $bool = $Class->format_available
51 This method is called when someone requests a module to be installed
52 via the superclass. This gives you the opportunity to check if all the
53 needed requirements to build and install this distribution have been
54 met.
55 For example, you might need a command line program, or a certain perl
57 module installed to do your job. Now is the time to check.
58 Simply return true if the request can proceed and false if it can not.
60 The "CPANPLUS::Dist::Base" implementation always returns true.
62 $bool = $dist->init
64 This method is called just after the new dist object is set up and
65 before the "prepare" method is called. This is the time to set up the
66 object so it can be used with your class.
67 For example, you might want to add extra accessors to the "status"
69 object, which you might do as follows:
70 $dist->status->mk_accessors( qw[my_implementation_accessor] );
72 The "status" object is implemented as an instance of the
74 "Object::Accessor" class. Please refer to its documentation for
75 details.
76 Return true if the initialization was successful, and false if it was
78 not.
79 The "CPANPLUS::Dist::Base" implementation does not alter your object
81 and always returns true.
82 $bool = $dist->prepare
84 This runs the preparation step of your distribution. This step is meant
85 to set up the environment so the "create" step can create the actual
86 distribution(file). A "prepare" call in the standard
87 "ExtUtils::MakeMaker" distribution would, for example, run "perl
88 Makefile.PL" to find the dependencies for a distribution. For a
89 "debian" distribution, this is where you would write all the metafiles
90 required for the "dpkg-*" tools.
91 The "CPANPLUS::Dist::Base" implementation simply calls the underlying
93 distribution class (Typically "CPANPLUS::Dist::MM" or
94 "CPANPLUS::Dist::Build").
95 Sets "$dist->status->prepared" to the return value of this function.
97 If you override this method, you should make sure to set this value.
98 $bool = $dist->create
100 This runs the creation step of your distribution. This step is meant to
101 follow up on the "prepare" call, that set up your environment so the
102 "create" step can create the actual distribution(file). A "create"
103 call in the standard "ExtUtils::MakeMaker" distribution would, for
104 example, run "make" and "make test" to build and test a distribution.
105 For a "debian" distribution, this is where you would create the actual
106 ".deb" file using "dpkg".
107 The "CPANPLUS::Dist::Base" implementation simply calls the underlying
109 distribution class (Typically "CPANPLUS::Dist::MM" or
110 "CPANPLUS::Dist::Build").
111 Sets "$dist->status->dist" to the location of the created distribution.
113 If you override this method, you should make sure to set this value.
114 Sets "$dist->status->created" to the return value of this function. If
116 you override this method, you should make sure to set this value.
117 $bool = $dist->install
119 This runs the install step of your distribution. This step is meant to
120 follow up on the "create" call, which prepared a distribution(file) to
121 install. A "create" call in the standard "ExtUtils::MakeMaker"
122 distribution would, for example, run "make install" to copy the
123 distribution files to their final destination. For a "debian"
124 distribution, this is where you would run "dpkg --install" on the
125 created ".deb" file.
126 The "CPANPLUS::Dist::Base" implementation simply calls the underlying
128 distribution class (Typically "CPANPLUS::Dist::MM" or
129 "CPANPLUS::Dist::Build").
130 Sets "$dist->status->installed" to the return value of this function.
132 If you override this method, you should make sure to set this value.
133 $bool = $dist->uninstall
135 This runs the uninstall step of your distribution. This step is meant
136 to remove the distribution from the file system. A "uninstall" call in
137 the standard "ExtUtils::MakeMaker" distribution would, for example, run
138 "make uninstall" to remove the distribution files the file system. For
139 a "debian" distribution, this is where you would run "dpkg --uninstall
140 PACKAGE".
141 The "CPANPLUS::Dist::Base" implementation simply calls the underlying
143 distribution class (Typically "CPANPLUS::Dist::MM" or
144 "CPANPLUS::Dist::Build").
145 Sets "$dist->status->uninstalled" to the return value of this function.
147 If you override this method, you should make sure to set this value.
