SYNOPSIS

12         use TAP::Parser::Source;
13         my $source = TAP::Parser::Source->new;
14         $source->raw( \'reference to raw TAP source' )
15                ->config( \%config )
16                ->merge( $boolean )

21         do { ... } if $source->meta->{is_file};
22         # see assemble_meta for a full list of data available

DESCRIPTION

25       A TAP source is something that produces a stream of TAP for the parser
26       to consume, such as an executable file, a text file, an archive, an IO
27       handle, a database, etc.  "TAP::Parser::Source"s encapsulate these raw
28       sources, and provide some useful meta data about them.  They are used
29       by TAP::Parser::SourceHandlers, which do whatever is required to
30       produce & capture a stream of TAP from the raw source, and package it
31       up in a TAP::Parser::Iterator for the parser to consume.
32
33       Unless you're writing a new TAP::Parser::SourceHandler, a plugin or
34       subclassing TAP::Parser, you probably won't need to use this module
35       directly.

METHODS

38   Class Methods
39       "new"
40
41        my $source = TAP::Parser::Source->new;
42
43       Returns a new "TAP::Parser::Source" object.
44
45   Instance Methods
46       "raw"
47
48         my $raw = $source->raw;
49         $source->raw( $some_value );
50
51       Chaining getter/setter for the raw TAP source.  This is a reference, as
52       it may contain large amounts of data (eg: raw TAP).
53
54       "meta"
55
56         my $meta = $source->meta;
57         $source->meta({ %some_value });
58
59       Chaining getter/setter for meta data about the source.  This defaults
60       to an empty hashref.  See "assemble_meta" for more info.
61
62       "has_meta"
63
64       True if the source has meta data.
65
66       "config"
67
68         my $config = $source->config;
69         $source->config({ %some_value });
70
71       Chaining getter/setter for the source's configuration, if any has been
72       provided by the user.  How it's used is up to you.  This defaults to an
73       empty hashref.  See "config_for" for more info.
74
75       "merge"
76
77         my $merge = $source->merge;
78         $source->config( $bool );
79
80       Chaining getter/setter for the flag that dictates whether STDOUT and
81       STDERR should be merged (where appropriate).  Defaults to undef.
82
83       "switches"
84
85         my $switches = $source->switches;
86         $source->config([ @switches ]);
87
88       Chaining getter/setter for the list of command-line switches that
89       should be passed to the source (where appropriate).  Defaults to undef.
90
91       "test_args"
92
93         my $test_args = $source->test_args;
94         $source->config([ @test_args ]);
95
96       Chaining getter/setter for the list of command-line arguments that
97       should be passed to the source (where appropriate).  Defaults to undef.
98
99       "assemble_meta"
100
101         my $meta = $source->assemble_meta;
102
103       Gathers meta data about the "raw" source, stashes it in "meta" and
104       returns it as a hashref.  This is done so that the
105       TAP::Parser::SourceHandlers don't have to repeat common checks.
106       Currently this includes:
107
108           is_scalar => $bool,
109           is_hash   => $bool,
110           is_array  => $bool,
111
112           # for scalars:
113           length => $n
114           has_newlines => $bool
115
116           # only done if the scalar looks like a filename
117           is_file => $bool,
118           is_dir  => $bool,
119           is_symlink => $bool,
120           file => {
121               # only done if the scalar looks like a filename
122               basename => $string, # including ext
123               dir      => $string,
124               ext      => $string,
125               lc_ext   => $string,
126               # system checks
127               exists  => $bool,
128               stat    => [ ... ], # perldoc -f stat
129               empty   => $bool,
130               size    => $n,
131               text    => $bool,
132               binary  => $bool,
133               read    => $bool,
134               write   => $bool,
135               execute => $bool,
136               setuid  => $bool,
137               setgid  => $bool,
138               sticky  => $bool,
139               is_file => $bool,
140               is_dir  => $bool,
141               is_symlink => $bool,
142               # only done if the file's a symlink
143               lstat      => [ ... ], # perldoc -f lstat
144               # only done if the file's a readable text file
145               shebang => $first_line,
146           }
147
148         # for arrays:
149         size => $n,
150
151       "shebang"
152
153       Get the shebang line for a script file.
154
155         my $shebang = TAP::Parser::Source->shebang( $some_script );
156
157       May be called as a class method
158
159       "config_for"
160
161         my $config = $source->config_for( $class );
162
163       Returns "config" for the $class given.  Class names may be fully
164       qualified or abbreviated, eg:
165
166         # these are equivalent
167         $source->config_for( 'Perl' );
168         $source->config_for( 'TAP::Parser::SourceHandler::Perl' );
169
170       If a fully qualified $class is given, its abbreviated version is
171       checked first.
