NAME Win32::CommandLine - Retrieve and reparse the Win32 command line VERSION This document describes `Win32::CommandLine' ($Version: 0.3.13.14 $). SYNOPSIS @ARGV = Win32::CommandLine::argv() if eval { require Win32::CommandLine; }; _or_ use Win32::CommandLine qw( command_line ); my $commandline = command_line(); ... DESCRIPTION This module is used to reparse the Win32 command line, automating better quoting and globbing of the command line. Globbing is full bash POSIX compatible globbing, including subshell expansions. With the use of the companion script (xx.bat) and doskey for macro aliasing, you can add full-fledged bash compatible string quoting/expansion and file globbing to any Win32 command. This module is compatible with both cmd.exe and 4nt/tcc shells. [cmd.exe] doskey type=call xx type $* type [a-c]*.pl doskey perl=call xx perl $* perl -e 'print "test"' [o/w FAILS without commandline reinterpretation] [TCC/TCMD/4NT] alias type=call xx type type [a-c]*.pl alias perl=call xx perl perl -e 'print "test"' [o/w FAILS without commandline reinterpretation] Note the bash compatible character expansion and globbing available, including meta-notations a{b,c}*. String/character expansion: '...' => literal (no escapes and no globbing within quotes) $'...' => ANSI C string escapes (\a, \b, \e, \f, \n, \r, \t, \v, \\, \', \n{1,3}, \xh{1,2}, \cx; all other \ =>\), no globbing within quotes "..." => literal (no escapes and no globbing within quotes) $"..." => same as "..." $( ... ) => subshell expansion $("...") => subshell expansion Globbing: \ Quote the next metacharacter [] Character class {} Multiple pattern * Match any string of characters ? Match any single character ~ Expand to current user home directory ~ Expands to user home directory for any defined user [ ONLY if {Win32, Win32::Security::SID, Win32::TieRegistry} are installed; o/w no expansion => pull off any leading non-quoted ~[name] (~ followed by word characters) => replace with home dir of [name] if exists, otherwise replace the characters) ~ Expands to value of environment variable "~" (if defined) [OVERRIDES ~ expansion] #?? verify and document which has priority INSTALLATION To install this module, run the following commands: perl Build.PL ./Build ./Build test ./Build install Or, if you're on a platform (like DOS or Windows) that doesn't require the "./" notation, you can do this: perl Build.PL Build Build test Build install The standard make idiom ( "perl Makefile.PL" -> "make" -> "make test" -> "make install") is also available (though deprecated) via a Makefile.PL passthrough script. Module::Build is still ultimately required for installation, and Makefile.PL will offer to download and install Module::Build if it is missing from your current installation. PPM installation bundles should also be available in the standard PPM repositories (i.e. ActiveState, trouchelle.com [http://trouchelle.com/ppm/package.xml]). Note: On ActivePerl installations, './Build install' will do a full installation using `ppm' (see ppm). RATIONALE Attempts were made using Win32::API and Inline::C. Win32::API attempt (causes GPFs): @rem = '--*-Perl-*-- @echo off if "%OS%" == "Windows_NT" goto WinNT perl -x -S "%0" %1 %2 %3 %4 %5 %6 %7 %8 %9 goto endofperl :WinNT perl -x -S %0 %* if NOT "%COMSPEC%" == "%SystemRoot%\system32\cmd.exe" goto endofperl if %errorlevel% == 9009 echo You do not have Perl in your PATH. if errorlevel 1 goto script_failed_so_exit_with_non_zero_val 2>nul goto endofperl @rem '; #!/usr/bin/perl -w #line 15 use Win32::API; Win32::API->Import("kernel32", "LPTSTR GetCommandLine()"); my $string = pack("Z*", GetCommandLine()); print "string[".length($string)."] = '$string'\n"; # ------ padding -------------------------------------------------------------------------------------- __END__ :endofperl Unfortunately, Win32::API causes a GPF and Inline::C is very brittle on Win32 systems (not compensating for paths with embedded strings). See URLref: http://www.perlmonks.org/?node_id=625182 for a more full explanation of the problem and initial attempts at a solution. DEPENDENCIES None.
