DESCRIPTION

This module is an Apache (version 2) handler for dynamically generating PNLP files for PAR::WebStart. See PAR::WebStart::PNLP for details of the content of a PNLP files.

Directives

The following PerlSetVar directives are used to control the content of the PNLP file; of these, only at least one WS_par must be specified.

PerlSetVar WS_codebase "lib/apps"

This specifies the base by which all relative URLs specified in the PNLP file will be resolved against. If this is not specified, the default root document directory will be assumed.

PerlSetVar WS_title "My App"

This specifies the title of the application.

PerlSetVar WS_vendor "me.com"

This specifies the vendor of the application.

PerlSetVar WS_homepage "docs/hello.html"

This specifies a link describing further details of the application; if it does not begin with http://, it will be assumed to use WS_codebase as the base.

PerlSetVar WS_description "A Perl WebStart Application"

This specifies a description of the application.

PerlSetVar WS_os "MSWin32"

This specifies that the application will only run on machines matching $Config{osname}.

PerlSetVar WS_arch "MSWin32-x86-multi-thread"

This specifies that the application will only run on machines matching $Config{archname}.

PerlSetVar WS_version "5.008006"

This specifies that the minimal perl version required (as given by $]) to run the application, and must be given in the form, for example, 5.008006 for perl-5.8.6.

PerlSetVar WS_perl_version "8"

This specifies that the application will only run on machines matching $Config{PERL_VERSION}.

PerlSetVar WS_no_sign 1

If set to a true value, this specifies that the par files will not be expected to be signed by Module::Signature (the default value is false, meaning par files are expected to be signed).

PerlSetVar WS_par "A.par"

This specifies a par file used within the application; additional files may be specified by multiple directives such as PerlAddVar WS_par "C.par".

PerlSetVar WS_main "A"

This specifies the name of the par file (without the .par extension) that contains the main script to be run. This directive is not needed if only one par file is specified. If this directive is not specified in the case of multiple par files, it will be assumed that the first par file specified by PerlSetVar WS_par contains the main script.

PerlSetVar WS_arg "--verbose"

This specifies an argument to be passed to the main script. Additional arguments may be added through a directive like PerlAddVar WS_arg "--debug". In addition, if the URL associated with the handler contains a query string, those arguments (split on the ; or & character) will be added to the arguments passed to the main script. For example, a query string of arg1=arg;arg2=3 will include the arguments (in order) arg1=arg and arg2=3 passed to the main script. Query string arguments are added to the argument list after any specified by PerlSetVar WS_arg.

PerlSetVar WS_long_opts 1

If this option is set to a true value, all arguments passed via either PerlSetVar/PerlAddVar WS_arg directives or by a query string will have two dashes (--) prepended to them when passed to the main script (for example, a query string of arg=4 will be passed to the main script as --arg=4. This may be useful if the main script uses Getopt::Long to process command-line options.

PerlSetVar WS_short_opts 1

If this option is set to a true value, all argumets passed via either PerlSetVar/PerlAddVar WS_arg directives or by a query string will have one dash (-) prepended to them when passed to the main script (for example, a query string of a=4 will be passed to the main script as -a=4. This may be useful if the main script uses Getopt::Std to process command-line options.

PerlSetVar WS_module "Tk"

This specifies additional modules, outside of the basic perl core, that the application needs; additional modules may be specified by multiple directives such as PerlAddVar WS_module "LWP".
