6 Padre::Perl - A more nuanced "Where is Perl" module than Probe::Perl
7
9 Even though it has only had a single release, Probe::Perl is the "best
10 practice" method for finding the current Perl interpreter, so that we
11 can make a system call to a new instance of the same Perl environment.
12
13 However, during the development of Padre we have found the feature set
14 of Probe::Perl to be insufficient.
15
16 "Padre::Perl" is an experimental attempt to improve on Probe::Perl and
17 support a wider range of situations. The implementation is being
18 contained to the Padre project until we have competently "solved" all
19 of the problems that we care about.
20
21 GUI vs Command Line
22 On some operating systems, different Perl binaries need to be called
23 based on whether the process will be executing in a graphical
24 environment versus a command line environment.
25
26 On Microsoft Windows perl.exe is the command line Perl binary and
27 wperl.exe is the windowing Perl binary.
28
29 On Mac OS X (Darwin) perl.exe is the command line Perl binary and
30 wxPerl.exe is a wxWidgets-specific Perl binary.
31
32 PAR Support
33 PAR executables do not typically support re-invocation, and
34 implementations that do are only a recent invention, and do not support
35 the normal Perl flags.
36
37 Once implemented, we may try to implement support for them here as
38 well.

41 "perl"
42 The "perl" function is equivalent to (and passes through to) the
43 "find_perl_interpreter" method of Probe::Perl.
44
45 It should be used when you simply need the "current" Perl executable
46 and don't have any special needs. The other functions should only be
47 used once you understand your needs in more detail.
48
49 Returns the location of current perl executable, or "undef" if it
50 cannot be found.
51
52 "cperl"
53 The "cperl" function is a Perl executable location function that
54 specifically tries to find a command line Perl. In some situations you
55 may critically need a command line Perl so that proper "STDIN",
56 "STDOUT" and "STDERR" handles are available.
57
58 Returns a path to a command line Perl, or "undef" if one cannot be
59 found.
60
61 "wxperl"
62 The "wxperl" function is a Perl executable location function that
63 specifically tries to find a windowing Perl for running wxWidgets
64 applications. In some situations you may critically need a wxWidgets
65 Perl so that a command line box is not show (Windows) or so that Wx
66 starts up properly at all (Mac OS X).
67
68 Returns a path to a Perl suitable for the execution of Wx-based
69 applications, or "undef" if one cannot be found.
