[SOLVED] texlive: texdoc not working

Slackware64-current, texlive 2018 upgraded. texlive-extra and texlive-docs upgraded from SBo. Older texlive-fonts removed before upgrade because fonts are now included in texlive-extra.

Using lua-5.1.5 from SBo.

Problem:
texdoc fails. Invoking texdoc to look for some documentation fails with the following:

eduardo:~]$ texdoc memoir
[string "/usr/share/texmf-dist/scripts/texdoc/search.t..."]:569: assertion failed!

This points out to line 569 of script search.tlu, which in its relevant part states:

-- get pre-hashed tlpdb info from a pseudo-cache file
function get_tlpinfo_from_dist()
(569)    local f = assert(kpse.find_file(C.data_tlpdb_name, 'texmfscripts'))
    s_meta, tlp_from_runfile, tlp_doclist = dofile(f)
end

Line 569 is marked by a parenthesis.

two things:

1. I ran mktexlsr both as a regular user and as root, to no avail.
2. Looks like texlive requires lua now, maybe an appropriate version should be included in Slackware, perhaps as an extra package.

Thanks in advance for any tips in resolving this annoyance.

I have no fix yet, sorry, something has changed with texdoc 3.0/texlive 2018.
I hope i find time the next days for further digging, i just wanted you to know that i saw your report.

Thanks Johannes.

I reported the bug upstream:

https://github.com/TeX-Live/texdoc/i...ment-406644351

This is what one of the developers wrote:

Now, it is surely because of lacking `texlive.tlpdb`. Perhaps, the TeX Live from Slackware also removed the database. The destributor, if they want to activate Texdoc, have to include `texlive.tlpdb` or they should generate a pre-hashed cache file before releasing as we decided in #2.

Thus, texdoc does not work most probably because it needs the 'texlive.tlpdb' file. Could you please try this?

Thanks,

Eduardo

Here is the fix, which i will apply in a similar way to the
texlive package:

su -
mkdir /tlpkg
wget -O /tlpkg/texlive.tlpdb http://tug.ctan.org/systems/texlive/tlnet/tlpkg/texlive.tlpdb
texdoc -DlM texlive-en |& grep cache-tlpdb.lua
mv /root/.texlive2018/texmf-var/texdoc/cache-tlpdb.lua \
  /usr/share/texmf-dist/scripts/texdoc/Data.tlpdb.lua
mktexlsr
rm -rf /tlpkg

It works!! Thank you!!
Marking the thread as solved.
