Description

This looks like an issue in Pod::Perldoc::ToTerm that adds ANSI sequences into the formatted output according to a current terminal: E.g. the NAME section title changes: -ESC[1mNAMEESC[0m +ESC[1mNAMEESC[m^O This is saved into a file and a pager, "/usr/bin/less -isr" probably, is called on that file. In the TERM=linux case /usr/bin/less comes to a conclusion that the file is a binary garbage and asks for permission to spoil a terminal. And indeed the TERM=linux output is not propebly displayed on Linux virtual terminal, an `O' letter hangs after the title. Whether it's a Pod::Perldoc::ToTerm or a terminal database bug I don't know. There were numerous bug reports to Pod-Perldoc CPAN distribution, e.g.: https://rt.cpan.org/Public/Bug/Display.html?id=120229 https://rt.cpan.org/Public/Bug/Display.html?id=88204 and that lead to Perl bug: https://rt.perl.org/Public/Bug/Display.html?id=131762 that was resolved by patching Pod::Perldoc to use plain text output without ANSI formatting (i.e. Pod::Perldoc::ToText instead of Pod::Perldoc::ToTerm). I'm keen to apply the Perl patch to Fedora <= 28. It will disappear the bold highlighting but it makes the text legible on all terminals. perl-Pod-Perldoc-3.28.01-1.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-9d12bea0f8 perl-Pod-Perldoc-3.28.01-1.fc28 has been pushed to the Fedora 28 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2018-9d12bea0f8 perl-Pod-Perldoc-3.28.01-1.fc28 has been pushed to the Fedora 28 stable repository. If problems still persist, please make note of it in this bug report. This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '28'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 28 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. |
