NAME Term::GnuScreen - control GNU screen VERSION Version 0.05 SYNOPSIS Term::GnuScreen provides a simple interface to control a GNU screen session via its command line interface. use Term::GnuScreen; my $screen = Term::GnuScreen->new(); $screen->windowlist; $screen->hardcopy('/tmp/my_hardcopy'); CONSTRUCTION session Sets the name of the screen session to which commands are send. If you also set "create" to a true value, this will become the new name of your screen session. See *-S* option for screen for a further discussion of this argument. create If create is set to a true value, a new screen session is created and detached automatically. If you do not provide a session name via *session*, this module generates one by calling ""term_gnuscreen" . $$ . int(rand(10000))". Settings this value after object creation has no effect at the moment. The newly created session will not be terminated after program execution. window Preselects a window. Defaults to 0. See *-p* option of screen for a further discussion of this argument. executable Return or set the screen binary to call. Defaults to the binary found by "File::Which::which("screen")". debugging If debugging is set to a true value, all commands are printed to STDERR. METHODS Term::GnuScreen implements all commands as stated in the texinfo document shipped with GNU screen. Whenever you call a command it is send via GNU screens -X parameter to the first running screen session and its current window. You can change session and window with the according object methods and construction parameters. Unless listed here, all remaining arguments are handed over to screen without further modification. The five commands bind, kill, meta, chdir, exec and umask are prefixed with a *s* (sbind, smeta, schdir, sexec and sumask) to distinguish them from the built-ins with the same name. call_screen This command is the working horse of Term::GnuScreen. It simply builds the command line to call and execute it. send_command Calls call_screen with the *-X* and all supplied parameters. Most functions are implemented by this method. hardcopy Write a hardcopy of the current window to a temporary file and returns the filename unless the filename is supplied as first argument. If the supplied filename is not absolute, the file is written relative to "hardcopydir". ERROR HANDLING Simple dies in case screen -X did not return with a return value of zero. Either $!, STDERR or STDOUT (which seems to be more helpful most times) are provided as error message for further investigation. AUTHOR Mario Domgoergen BUGS AND LIMITATIONS It seems not to be possible to question a specific screen session about its state, so this module basically just sends commands to a screen session without knowing if the command succeeded or was even syntactically correct. This module needs a lot more testing. Please report any bugs or feature requests to "bug-term-gnuscreen at rt.cpan.org", or through the web interface at . I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.
