NAME

       gcap - Youtube closed caption downloader

SYNOPSIS

       gcap [-i] [-t] [-r <regexp>] [--proxy=<addr> | --no-proxy]
	    [--help] <url> | <video_id>

DESCRIPTION

       gcap is a command line tool for downloading Youtube closed captions.  The downloaded closed captions are saved in SubRip (srt) file format.
       The srt files are saved as "$videoid_$langid.srt" by default.

OPTIONS

       --help
	   Print help and exit.

       --version
	   Print version and exit.

       -q, --quiet
	   Be quiet.

       -i, --interactive
	   Open the interactive prompt which can be used to select the items.  gcap selects all items by default. See also "INTERACTIVE PROMPT".

       -t, --title
	   Parse video title and use it in the output filename(s) instead of video ID. The default is no.

       -r, --regexp=arg
	   Cleanup video title using the specified arg regular expression.  The default is "/(w|s)/g".

       --proxy arg
	   Use arg for HTTP proxy, e.g. "http://foo:1234". Overrides the http_proxy environment setting.

       --no-proxy
	   Disable use of HTTP proxy. Overrides both "--proxy" and http_proxy environment settings.

INTERACTIVE PROMPT

       Use the "--interactive" switch to open the prompt. Note that gcap uses (as of 0.1.0) the Umph::Prompt module for this. Once the prompt
       opens, type "help" to get a list of commands available to the prompt.

EXAMPLES

       gcap 0QRO3gKj3qw
       gcap "http://www.youtube.com/watch?v=0QRO3gKj3qw"
	   Both yield the same results.

       gcap -ti 0QRO3gKj3qw
	   Same as above two but use video title in the filename and choose which of the closed captions should be downloaded.

EXIT STATUS

       Exits 0 on success, otherwise 1.

FILES

       $HOME/.gcaprc, for example:
	   echo "--interactive" >> ~/.gcaprc

NOTES

       Availability
	   The following error message produced by gcap (or the XML::DOM module) typically indicates that the video does not have any closed
	   captions available for it (URL omitted for brewity):

	     Couldn't parsefile [...] with LWP: no element found at line 1,
	     column 0, byte -1 at [...]/XML/Parser.pm [...]

       http_proxy
	   gcap depends on XML::DOM which uses LWP::UserAgent to download the data. Note that LWP::UserAgent reads http_proxy environment setting.
	   e.g.:

	     env http_proxy=http://foo:1234 gcap video_id

NAME

       XML::DOM::Parser - An XML::Parser that builds XML::DOM document structures

SYNOPSIS

	use XML::DOM;

	my $parser = new XML::DOM::Parser;
	my $doc = $parser->parsefile ("file.xml");
	$doc->dispose; # Avoid memory leaks - cleanup circular references

DESCRIPTION

       XML::DOM::Parser extends XML::Parser

       The XML::Parser module was written by Clark Cooper and is built on top of XML::Parser::Expat, which is a lower level interface to James
       Clark's expat library.

       XML::DOM::Parser parses XML strings or files and builds a data structure that conforms to the API of the Document Object Model as described
       at http://www.w3.org/TR/REC-DOM-Level-1 <http://www.w3.org/TR/REC-DOM-Level-1>.	See the XML::Parser manpage for other additional
       properties of the XML::DOM::Parser class.  Note that the 'Style' property should not be used (it is set internally.)

       The XML::Parser NoExpand option is more or less supported, in that it will generate EntityReference objects whenever an entity reference is
       encountered in character data. I'm not sure how useful this is. Any comments are welcome.

       As described in the synopsis, when you create an XML::DOM::Parser object, the parse and parsefile methods create an XML::DOM::Document
       object from the specified input. This Document object can then be examined, modified and written back out to a file or converted to a
       string.

       When using XML::DOM with XML::Parser version 2.19 and up, setting the XML::DOM::Parser option KeepCDATA to 1 will store CDATASections in
       CDATASection nodes, instead of converting them to Text nodes.  Subsequent CDATASection nodes will be merged into one. Let me know if this
       is a problem.

Using LWP to parse URLs
       The parsefile() method now also supports URLs, e.g. http://www.erols.com/enno/xsa.xml.  It uses LWP to download the file and then calls
       parse() on the resulting string.  By default it will use a LWP::UserAgent that is created as follows:

	use LWP::UserAgent;
	$LWP_USER_AGENT = LWP::UserAgent->new;
	$LWP_USER_AGENT->env_proxy;

       Note that env_proxy reads proxy settings from environment variables, which is what I need to do to get thru our firewall. If you want to
       use a different LWP::UserAgent, you can either set it globally with:

	XML::DOM::Parser::set_LWP_UserAgent ($my_agent);

       or, you can specify it for a specific XML::DOM::Parser by passing it to the constructor:

	my $parser = new XML::DOM::Parser (LWP_UserAgent => $my_agent);

       Currently, LWP is used when the filename (passed to parsefile) starts with one of the following URL schemes: http, https, ftp, wais,
       gopher, or file (followed by a colon.)  If I missed one, please let me know.

       The LWP modules are part of libwww-perl which is available at CPAN.
