5.00 - 2022-11-25: Changes
Drop support for Perl 5.8. The minimum required version is Perl 5.10.
The default output encoding of Pod::Man on non-EBCDIC systems is now
UTF-8. The utf8 option (-u or --utf8 to pod2man) is now ignored, since
it is the default. See the ENCODING section of its documentation for
testing results and further discussion. (#68741)
Pod::Man now supports an encoding option (-e or --encoding to pod2man),
to change the output encoding to any encoding recognized by Encode, or
the special values groff or roff. Setting it to roff requests the old
behavior of using character substitutions and *roff escapes to generate
ASCII-only output (the default prior to this version).
Pod::Man now supports the groff output encoding, which replaces all
non-ASCII characters with \[uNNNN] escapes. This escape was not
supported by the originally *roff implementation, but it is supported
by groff and mandoc and allows proper representation of Unicode
characters. This output format has no known advantages in portability
over UTF-8 on non-EBCDIC systems. It is the default output format on
EBCDIC systems, and when the Encode module is not available. (#73804)
Pod::Man no longer does guesswork transformations that only affected
troff output. Formatting manual pages with troff is exceptionally
rare, and this magic caused constant maintenance issues. This means
"--" is no longer changed to an em-dash, strings of capital letters
aren't made a bit smaller, no attempt is made to change double quotes
to paired quotes, and no special formatting is done for C++. (#132007)
Guesswork (formatting rules based on heuristics intended for Perl
documentation) can now be disabled or selectively enabled in Pod::Man
with the guesswork option (--guessword to pod2man). (#143668)
Pod::Text now supports an encoding option (-e or --encoding to
pod2text) to force the output encoding, similar to Pod::Man. The utf8
option (-u or --utf8 to pod2text) is still supported and is equivalent
to setting encoding to UTF-8.
Pod::Text now defaults to UTF-8 encoding if it sees a non-ASCII
character on a non-EBCDIC system and the input encoding is not
specified. This should fix rendering of E<> escapes of non-ASCII
characters in POD files that don't specify an input encoding, at the
cost of assuming UTF-8 output. Pod::Text also now commits to an
encoding the first time it outputs a non-ASCII character and sticks
with that encoding for the rest of the file, even if the detected or
declared input encoding changes. (#102631)
Stop using a PerlIO encoding layer for Pod::Text output and instead
use Encode. If a PerlIO encoding layer is already set, trust it and do
no encoding. This fixes encoding problems with output to a string.
Add a coding tag comment to the start of Pod::Man output if the output
encoding is not ASCII. groff's preconv program and FreeBSD's mandoc
will use this line to determine the input encoding.
Pod::Man now supports a language option (--language to pod2man) that
adds groff language configuration commands to the start of the output.
This is required for proper line breaking of Japanese and Chinese text
when the manual page is not installed in a language-specific directory
so that the man program knows to add that configuration automatically.
Unfortunately, the commands added when this option is used are
groff-specific. Thanks to zynldyx for the bug report and suggested
fix.
Pod::Man now converts Unicode zero-width spaces (U+200B) to the *roff
escape \:, which indicates a line break point without a space or
hyphen. (Unfortunately, groff does not honor U+200B itself as a line
break point.) This escape is not part of the language defined in CSTR
this escape won't cause problems. (Debian Bug#941980)
Pod::Man and Pod::Text now correctly honor S<> wrapping L<> with an
anchor and URL, and make the space between the anchor and URL
nonbreaking. (#143768)
Clear the current font before changing fonts in all Pod::Man output,
not just headings. groff 1.22.4 does not clear bold or italic when
seeing \f(CW font change, which meant bold and italic were extending
farther than they should without this change. (#143667)
Honor the quotes, lquote, and rquote configuration parameters to
Pod::Man for C<> text inside the special NAME section. (#143967)
Pod::Man suppresses quote marks around some additional cases of Perl
code in C<> where the intent had been to suppress the quotes but there
were various bugs in the matching regular expressions. This primarily
affects method calls and negative numbers.
Avoid non-standard *roff escape in the troff accent mark definition for
an acute accent. \h"..." was used instead of \h'...' as seen in the
other accent mark definitions. This error appears to have existed
since the first version of Pod::Man. Thanks, Paul Evans. (GitHub #14)
Document that nroff adds two spaces after each sentence when reflowing,
and therefore if you want formatted Pod::Man output to consistently
have one space after each sentence, you will have to avoid ending a
sentence at the end of a line in the middle of a paragraph.
Committer: Adjust Porting/Maintainers.pl and Porting/sync-with-cpan to
reflect upstream acceptance of customizations in core distribution.
