Originally created by @jordanenglish on GitHub (Oct 27, 2020).

I'm trying to install BookStack on RHEL8 and get going down various holes of research trying to get php-tidy to work.

PHP installed version from Red Hat for RHEL8 is 7.2.24.

Even going to a site looking for the package turns up no results:https://pkgs.org/download/php-tidy

I have seen a few guides mention using Remi repo, but I don't feel comfortable using that for production.

Any ideas?

I am sorry that i cant directly help, But this was two weeks ago a reason for me to switch from centos 8 to Debian 10,

Maybe someone with more knowladge can show you a way on RHEL. I was totaly new to a RPM system and just give it a try.

On Debian 10 it the intallation works like a charm. Not sure this can help you.

I'm afraid that without compiling your own PHP source you might be out of luck without wanting to use the remi repo.

Generally the dependency on lib-tidy has proved to be a pain for some environments.
It was only really used by a package for generating diffs between revisions.

This weekend I've ported a c# library to PHP for use in BookStack from the next release:

Since the new non-tidy-reliant library has now been implemented I'll close this off. This change will be part of the next feature release v0.31.
