NAME

6       Catalyst::Helper - Bootstrap a Catalyst application
7

SYNOPSIS

9         catalyst.pl <myappname>
10

DESCRIPTION

12       This module is used by catalyst.pl to create a set of scripts for a new
13       catalyst application. The scripts each contain documentation and will
14       output help on how to use them if called incorrectly or in some cases,
15       with no arguments.
16
17       It also provides some useful methods for a Helper module to call when
18       creating a component. See "METHODS".
19

SCRIPTS

21   _create.pl
22       Used to create new components for a catalyst application at the
23       development stage.
24
25   _server.pl
26       The catalyst test server, starts an HTTPD which outputs debugging to
27       the terminal.
28
29   _test.pl
30       A script for running tests from the command-line.
31
32   _cgi.pl
33       Run your application as a CGI.
34
35   _fastcgi.pl
36       Run the application as a fastcgi app. Either by hand, or call this from
37       FastCgiServer in your http server config.
38

HELPERS

40       The "_create.pl" script creates application components using Helper
41       modules. The Catalyst team provides a good number of Helper modules for
42       you to use. You can also add your own.
43
44       Helpers are classes that provide two methods.
45
46           * mk_compclass - creates the Component class
47           * mk_comptest  - creates the Component test
48
49       So when you call "scripts/myapp_create.pl view MyView TT", create will
50       try to execute Catalyst::Helper::View::TT->mk_compclass and
51       Catalyst::Helper::View::TT->mk_comptest.
52
53       See Catalyst::Helper::View::TT and
54       Catalyst::Helper::Model::DBIC::Schema for examples.
55
56       All helper classes should be under one of the following namespaces.
57
58           Catalyst::Helper::Model::
59           Catalyst::Helper::View::
60           Catalyst::Helper::Controller::
61
62   COMMON HELPERS
63       ·   Catalyst::Helper::Model::DBIC::Schema - DBIx::Class models
64
65       ·   Catalyst::Helper::View::TT - Template Toolkit view
66
67       ·   Catalyst::Helper::Model::LDAP
68
69       ·   Catalyst::Helper::Model::Adaptor - wrap any class into a Catalyst
70           model
71
72       NOTE
73
74       The helpers will read author name from /etc/passwd by default.  To
75       override, please export the AUTHOR variable.
76

METHODS

78   mk_compclass
79       This method in your Helper module is called with $helper which is a
80       Catalyst::Helper object, and whichever other arguments the user added
81       to the command-line. You can use the $helper to call methods described
82       below.
83
84       If the Helper module does not contain a "mk_compclass" method, it will
85       fall back to calling "render_file", with an argument of "compclass".
86
87   mk_comptest
88       This method in your Helper module is called with $helper which is a
89       Catalyst::Helper object, and whichever other arguments the user added
90       to the command-line. You can use the $helper to call methods described
91       below.
92
93       If the Helper module does not contain a "mk_compclass" method, it will
94       fall back to calling "render_file", with an argument of "comptest".
95
96   mk_stuff
97       This method is called if the user does not supply any of the usual
98       component types "view", "controller", "model". It is passed the $helper
99       object (an instance of Catalyst::Helper), and any other arguments the
100       user typed.
101
102       There is no fallback for this method.
103

INTERNAL METHODS

105       These are the methods that the Helper classes can call on the <$helper>
106       object passed to them.
107
108   render_file ($file, $path, $vars, $perms)
109       Render and create a file from a template in DATA using Template
110       Toolkit. $file is the relevent chunk of the __DATA__ section, $path is
111       the path to the file, $vars is the hashref as expected by Template
112       Toolkit and $perms are desired permissions (or system defaults if not
113       set).
114
115   get_file ($class, $file)
116       Fetch file contents from the DATA section. This is used internally by
117       "render_file".  $class is the name of the class to get the DATA section
118       from.  __PACKAGE__ or ( caller(0) )[0] might be sensible values for
119       this.
120
121   mk_app
122       Create the main application skeleton. This is called by catalyst.pl.
123
124   mk_component ($app)
125       This method is called by create.pl to make new components for your
126       application.
127
128   mk_dir ($path)
129       Surprisingly, this function makes a directory.
130
131   mk_file ($file, $content)
132       Writes content to a file. Called by "render_file".
133
134   next_test ($test_name)
135       Calculates the name of the next numbered test file and returns it.
136       Don't give the number or the .t suffix for the test name.
137
138   get_sharedir_file
139       Method for getting a file out of share/
140
141   render_file_contents
142       Process a Template::Toolkit template.
143
144   render_sharedir_file
145       Render a template/image file from our share directory
146

NOTE

148       The helpers will read author name from /etc/passwd by default.  To
149       override, please export the AUTHOR variable.
