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 TAP::Parser::SourceHandlers, which do whatever is required to produce & capture a stream of TAP from the raw source, and package it up in a TAP::Parser::Iterator for the parser to consume.
Unless you’re writing a new TAP::Parser::SourceHandler, a plugin or subclassing TAP::Parser, you probably won’t need to use this module directly.
"new"
my $source = TAP::Parser::Source−>new;
Returns a new "TAP::Parser::Source" object.
"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 "assemble_meta" 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 "config_for" 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 "raw" source, stashes it in "meta" and returns it as a hashref. This is done so that the TAP::Parser::SourceHandlers 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 "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.
