VERSION
Version 3.26
SYNOPSIS
use TAP::Parser::Source;
my $source = TAP::Parser::Source->new;
$source->raw( \'reference to raw TAP source' )
->config( \%config )
->merge( $boolean )
->switches( \@switches )
->test_args( \@args )
->assemble_meta;
do { ... } if $source->meta->{is_file};
# see assemble_meta for a full list of data available
DESCRIPTION
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::Source"s 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.
METHODS
Class Methods
"new"
my $source = TAP::Parser::Source->new;
Returns a new "TAP::Parser::Source" object.
Instance Methods
"raw"
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).
"meta"
my $meta = $source->meta;
$source->meta({ %some_value });
Chaining getter/setter for meta data about the source. This defaults
to an empty hashref. See the assemble_meta entry elsewhere in this
document for more info.
"has_meta"
True if the source has meta data.
"config"
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 the config_for entry elsewhere in this document for
more info.
"merge"
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.
"switches"
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.
"test_args"
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.
"assemble_meta"
my $meta = $source->assemble_meta;
Gathers meta data about the the raw entry elsewhere in this document
source, stashes it in the meta entry elsewhere in this document 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,
"shebang"
Get the shebang line for a script file.
my $shebang = TAP::Parser::Source->shebang( $some_script );
May be called as a class method
"config_for"
my $config = $source->config_for( $class );
Returns the config entry elsewhere in this document 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.
