Using strawberry-perl-5.24.1.1-64bit-portable on my Windows 10 machine,
any invocation of perldoc toward valid documentation returns the error​:
Invalid parameter - -R

On the bright side requests for documentation of uninstalled modules
responds correctly.

FWIW​: I've also installed 5.24.1 via perlbrew on my Mac and it behaves
correctly.

I'm a bit confused here. You're reporting a problem with 'perldoc', which is an executable program distributed with the Perl 5 core distribution (and presumably included in Strawberry Perl). But, ...

On the bright side requests for documentation of uninstalled modules
responds correctly.

FWIW​: I've also installed 5.24.1 via perlbrew on my Mac and it
behaves
correctly.

... 'perlbrew' is an executable which is part of the App​::perlbrew distribution from CPAN. It's not part of the Perl 5 core distribution (though it is, of course, used to install different versions of perl beneath your home directory).

Can you provide a few specific examples of your 'perldoc' problem -- both what doesn't work and what does?

Thank you very much.

VERSION

DESCRIPTION
  Dancer2 is the new generation of Dancer, the lightweight web-framework
  for Perl. Dancer2 is a complete rewrite based on Moo.

  Dancer2 can optionally use XS modules for speed, but at its core remains
  fatpackable (packable by App​::FatPacker) so you could easily deploy
  Dancer2 applications on hosts that do not support custom CPAN modules.

  Dancer2 is easy and fun​:

  use Dancer2;
  get '/' => sub { "Hello World" };
  dance;

  This is the main module for the Dancer2 distribution. It contains logic
  for creating a new Dancer2 application.

Thanks for looking into this. Can you post what happens in Strawberry Perl (preferably both 5.24.0 and 5.24.1) when you seek Perl's core documentation, e.g.​:

#####
perldoc perlvar
#####

We'll have to determine whether this problem is specific to the Strawberry Perl build of 5.24.1 or is more generally a problem with 5.24.1 on Windows.

Thank you very much.

I want to know what's producing that error message. Doesn't seem to be
perldoc itself, and it only arises when there is documentation to show.
I suspect that perldoc is supplying a -R parameter to a pager, but the
pager isn't the one that perldoc expects. perldoc does try to add -R
as an option to less, by adding it to $ENV{LESS}.

The bug is already reported upstream[1], it was broken by this[2] commit.

[p5pRT]

From @jkeenan

This problem appears to be a regression between 5.24.0 and 5.24.1. So I am adding it as a blocker for any 5.24.2.

I am also adding it as a blocker for 5.26.0, as version 3.27 of Pod-Perldoc (which is maintained upstream on cpan) is already in blead.

Thank you very much.

I don't see this problem in Strawberry Perl 5.24.0 on Windows 10. I will
attempt an install of Strawberry Perl 5.24.1 and test the following​:

On Windows 7, no problem with Strawberry Perl 5.24.0, but with Strawberry
Perl 5.24.1​:

###############
C​:\_64\strawberry5.24.1>perldoc Math​::BigInt

and also in 5.25.9 (built by me using gcc-5.3.0)​:

###############
C​:\_64>perl -le "print $];"
5.025009

C​:\_64>perldoc Math​::BigInt
Invalid parameter - -R

###############

Is there no testing of perldoc output in the test suite ?

(I haven't built a devel perl since 5.25.9 was released.)

On Windows 7, no problem with Strawberry Perl 5.24.0 ....

However, if (on 5.24.0) I update Pod​::Perldoc to the same version (namely
3.27) as ships with Strawberry Perl 5.24.1 then I do get the same behaviour​:

#################
C​:\_64\strawberry5.24.0-ld>perl -le "print $]"
5.024000

C​:\_64\strawberry5.24.0-ld>perldoc Math​::BigInt
Invalid parameter - -R

C​:\_64\strawberry5.24.0-ld>pmver Pod​::Perldoc
3.27

#################

Also, installing Pod-Perldoc-3.27 on Strawberry Perl 5.22.0 introduces the
same error to that build of perl.

Something is apparently amiss with Pod​::Perldoc.

Cheers,
Rob

This patch to Pod-Perldoc.pm fixes the error for me​:

The problem being, apparently, that '-R' is an invalid switch for 'more' on
Windows.

That introduces a new scope, so the local() will not apply for long enough on platforms where it should happen.
