I am using Debian 10 and Lyx 2.3.2. In my thesis (2002) I used the algolyx package and it worked fine in 2002. But I have been updating my thesis to fix a few things (a bad idea i know) and in the updated version most of my algorithms printed properly but a few failed for reasons I do not understand. I seems like a Lyx or Latex error due to using upgraded Lyx/Latex software since I haven't changed the lyx code or latex code (not necessarily true of course but not the issue here anyway).
Rather than track this issue down I decided to use the enumitem
package and rewrite the
algorithms that Lyx/Latex could no longer handle.
Unfortunately, this also failed because of what appeared to be a bug
in the enumitem package.
So I emailed the enumitem package maintainer with a sample piece of
latex code generated by Lyx demonstrating the bug. (Lesson learned:
Do not use Lyx to generate latex code demonstrating a bug in Latex.)
Anyway the maintainer determined that there was a '\noindent' in the
latex code that
shouldn't be there and removing it solved the problem. So the problem is not a
enumitem package bug!
Alas, I do not know why Lyx added the '\noindent' code. I did not
tell it to do so and so
now I (foolishly?) assume I have found a Lyx bug!
Can anyone tell me if this is a Lyx bug and if not then how do I get
Lyx to not add the
'offending \noindent' code?
I have attached the problematic Lyx file and the pdflatex tex file
generated from it containing
the 'noindent' code.
While I'm here i'd like to point out that when I run Lyx on this file
(and most other Lyx files)
I get the message:
'step: Counter does not exist: enum' many times.
If anyone can shed light on why I get this message that would me most helpful.
Thanks for any help received.
