.SH "NAME"
gcap \- Youtube closed caption downloader
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
gcap [\-i] [\-t] [\-r <regexp>] [\-\-proxy=<addr> | \-\-no\-proxy]
     [\-\-help] <url> | <video_id>
.SH "DESCRIPTION"
.IX Header "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 \*(L"$videoid_$langid.srt\*(R" by default.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print help and exit.
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
Print version and exit.
.IP "\fB\-q, \-\-quiet\fR" 4
.IX Item "-q, --quiet"
Be quiet.
.IP "\fB\-i, \-\-interactive\fR" 4
.IX Item "-i, --interactive"
Open the interactive prompt which can be used to select the items.
gcap selects \fIall\fR items by default. See also \*(L"\s-1INTERACTIVE PROMPT\*(R"\s0.
.IP "\fB\-t, \-\-title\fR" 4
.IX Item "-t, --title"
Parse video title and use it in the output filename(s) instead of
video \s-1ID.\s0 The default is no.
.IP "\fB\-r, \-\-regexp\fR=arg" 4
.IX Item "-r, --regexp=arg"
Cleanup video title using the specified \fIarg\fR regular expression.
The default is \*(L"/(\ew|\es)/g\*(R".
.IP "\fB\-\-proxy\fR \fIarg\fR" 4
.IX Item "--proxy arg"
Use \fIarg\fR for \s-1HTTP\s0 proxy, e.g. \*(L"http://foo:1234\*(R". Overrides the http_proxy
environment setting.
.IP "\fB\-\-no\-proxy\fR" 4
.IX Item "--no-proxy"
Disable use of \s-1HTTP\s0 proxy. Overrides both \f(CW\*(C`\-\-proxy\*(C'\fR and http_proxy environment
settings.
.SH "INTERACTIVE PROMPT"
.IX Header "INTERACTIVE PROMPT"
Use the \f(CW\*(C`\-\-interactive\*(C'\fR 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 \*(L"help\*(R" to get a list of commands available to the prompt.
.SH "EXAMPLES"
.IX Header "EXAMPLES"

.IX Item "gcap http://www.youtube.com/watch?v=0QRO3gKj3qw"
.PD
Both yield the same results.
.IP "\fBgcap \-ti 0QRO3gKj3qw\fR" 4
.IX Item "gcap -ti 0QRO3gKj3qw"
Same as above two but use video title in the filename and choose which
of the closed captions should be downloaded.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
Exits 0 on success, otherwise 1.
.SH "FILES"
.IX Header "FILES"
.ie n .IP "$HOME/.gcaprc, for example:" 4

.SH "NOTES"
.IX Header "NOTES"
.IP "\fBAvailability\fR" 4
.IX Item "Availability"
The following error message produced by gcap (or the \s-1XML::DOM\s0 module)
typically indicates that the video does not have any closed captions
available for it (\s-1URL\s0 omitted for brewity):
.Sp
.Vb 2

\&  column 0, byte \-1 at [...]/XML/Parser.pm [...]
.Ve
.IP "\fBhttp_proxy\fR" 4
.IX Item "http_proxy"
gcap depends on \s-1XML::DOM\s0 which uses LWP::UserAgent to download
the data. Note that LWP::UserAgent reads http_proxy environment
setting. e.g.:
.Sp
.Vb 1
\&  env http_proxy=http://foo:1234 gcap video_id
