A TAP source is something that produces a stream of TAP for the parser to
consume, such as an executable file, a text file, an archive, an IO handle, a
database, etc. TAP::Parser::Sources encapsulate these raw sources, and
provide some useful meta data about them. They are used by
the TAP::Parser::SourceHandler manpages, which do whatever is required to produce &
capture a stream of TAP from the raw source, and package it up in a
the TAP::Parser::Iterator manpage for the parser to consume.
Unless you're writing a new the TAP::Parser::SourceHandler manpage, a plugin or
subclassing the TAP::Parser manpage, you probably won't need to use this module directly.
my $source = TAP::Parser::Source->new;
Returns a new TAP::Parser::Source object.
my $raw = $source->raw;
$source->raw( $some_value );
Chaining getter/setter for the raw TAP source. This is a reference, as it may
contain large amounts of data (eg: raw TAP).
my $meta = $source->meta;
$source->meta({ %some_value });
Chaining getter/setter for meta data about the source. This defaults to an
empty hashref. See assemble_meta for more info.
True if the source has meta data.
my $config = $source->config;
$source->config({ %some_value });
Chaining getter/setter for the source's configuration, if any has been provided
by the user. How it's used is up to you. This defaults to an empty hashref.
See config_for for more info.
my $merge = $source->merge;
$source->config( $bool );
Chaining getter/setter for the flag that dictates whether STDOUT and STDERR
should be merged (where appropriate). Defaults to undef.
my $switches = $source->switches;
$source->config([ @switches ]);
Chaining getter/setter for the list of command-line switches that should be
passed to the source (where appropriate). Defaults to undef.
my $test_args = $source->test_args;
$source->config([ @test_args ]);
Chaining getter/setter for the list of command-line arguments that should be
passed to the source (where appropriate). Defaults to undef.
my $meta = $source->assemble_meta;
Gathers meta data about the raw source, stashes it in meta and returns
it as a hashref. This is done so that the the TAP::Parser::SourceHandler manpages don't
have to repeat common checks. Currently this includes:
is_scalar => $bool,
is_hash => $bool,
is_array => $bool,
# for scalars:
length => $n
has_newlines => $bool
# only done if the scalar looks like a filename
is_file => $bool,
is_dir => $bool,
is_symlink => $bool,
file => {
# only done if the scalar looks like a filename
basename => $string, # including ext
dir => $string,
ext => $string,
lc_ext => $string,
# system checks
exists => $bool,
stat => [ ... ], # perldoc -f stat
empty => $bool,
size => $n,
text => $bool,
binary => $bool,
read => $bool,
write => $bool,
execute => $bool,
setuid => $bool,
setgid => $bool,
sticky => $bool,
is_file => $bool,
is_dir => $bool,
is_symlink => $bool,
# only done if the file's a symlink
lstat => [ ... ], # perldoc -f lstat
# only done if the file's a readable text file
shebang => $first_line,
}
# for arrays:
size => $n,
Get the shebang line for a script file.
my $shebang = TAP::Parser::Source->shebang( $some_script );
May be called as a class method
my $config = $source->config_for( $class );
Returns config for the $class given. Class names may be fully qualified
or abbreviated, eg:
# these are equivalent
$source->config_for( 'Perl' );
$source->config_for( 'TAP::Parser::SourceHandler::Perl' );
If a fully qualified $class is given, its abbreviated version is checked first.
