[Libguestfs] [PATCH] podwrapper: simplify external references pointing to self

When convering a POD documentation, possibily combining various sub-documents together, simplify the L<> links that explicitly point to the very same documentation being generated. For example, when generating the virt-builder documentation, links like L<virt-builder(1)/SECTION> will be turned into L</SECTION> thus not making Pod::Simple parse them as external reference. While it is a slightly crude hack, it seems there's no easy way to process the link parsing with Pod::Simple subclasses. --- podwrapper.pl.in | 3 +++ 1 file changed, 3 insertions(+) diff --git a/podwrapper.pl.in b/podwrapper.pl.in index 0bb7b28..b354db6 100755 --- a/podwrapper.pl.in +++ b/podwrapper.pl.in @@ -278,6 +278,9 @@ foreach (@inserts) { if $content eq $oldcontent; } +# Turn external links to this man page into simple cross-section links. +$content =~ s,\QL<$name($section)/\E,L</,g; + # Perform @verbatims. foreach (@verbatims) { my @a = split /:/, $_, 2; -- 2.1.0
