The running script that I gave you checks for the AUX file, XREF file
and TOC, and it continues the compilation until they don't change -
so when you don't change sections, cross-references and other stuff
that is written to these files, it should do only one compilation. If
these files change between compilations, it will run as many
compilations as specified in max_compilations variable. Check how
large it is, maybe we were experimenting with it and it is too large.
Value of 3 should be enough.

The problem is mostly with hyperlinks and large tables. But all of
this depends on the auxilary files the script checks, so you won't get
any better results with the log parsing.

Yes, it is too much. You can try to print the number of compilations
used in the checksum script by adding this line before return status
in Make:add("myhtlatex", ...) function:
print("Number of compilations: " .. compilation_count)
I am not sure which version of this file you use now, I know there are
multiple versions and I am afraid that I cannot find the most recent
one, so I cannot post the whole function here. Anyway, if the number
is too large, it can be caused by some bug in the script.
Best regards,
Michal

[tex4ht] Can one use tex4ht log file to check if more runs are needed?
Currently, when I compile using lualatex, the script checks at the end of each compilation if some specific messages are in the log file, which tells it to call lualatex one more time. Over the years I collected these messages Rerun. Rerun, Rerun to get outlines right Rerun to get it removed Temporary extra page added at the end may have changed Rerun to get cross-references right shipout/lastpage|Table widths have changed (I can't just check for "Rerun" because that can give false positive, since package rerunfilecheck generate log message with the word "Rerun" in it. I do not even load this package, but is loaded by other packages). For tex4ht, I use Michal's lua script that he kindly wrote for me long time ago which does some magic and checksums to decide if more runs are needed with maximum number of 6 runs. But always not sure if it is running more times than needed or not. My question here is this: Could I use similar method for tex4ht and just check the tex4ht log file for messages? This is easier for me to do, since I can use the same "grep -E" command. If so, will searching for same messages above work for tex4ht? Or does it generate other messages not listed above which indicates more calls to make4ht is needed? I know by default make4ht will run 3-times, but I can change it to run one time only each time it is called, and this way I can call it from the script as many times as needed based on if I find it needs to run again.
