What about this change? With the attached patch I get:
Version 2.4.0~RC1.devel
(not released yet)
Built from git commit hash 0c6101b0
Qt Version (run-time): 5.15.10 on platform wayland
Qt Version (compile-time): 5.15.10
OS Version (run-time): Fedora Linux 39 (KDE Plasma Prerelease)
Python detected: 3.12.0rc1 (/usr/bin/python3)
We have several recent threads, for example on Mac systems, where this
output is useful without the need to go to a terminal.
IMHO it is also more relevant than what we get now.
As a bonus if no python is detected then the output is:
Python detected: None
None is not supposed to be translated, it is (Monty) Python's humour.
:-D

The document may not compile correctly if you do not install it." And maybe direct the user to the relevant part of the documentation, where we could give basic hints about how to install missing packages.

What do you think it constitutes a minimal distribution, or an average distribution, in terms of the requirements for latex packages? One (extreme) option would be to look into configure and depend on all the latex packages that it searches. In terms of implementation we can easily define other metapackages whose sole purpose is to hold the dependencies. An unrelated example that shows what I mean would be an hypothetical lyx-docbook sub-package that requires all the packages necessary to fully support the docbook tools required by LyX. In this way we ensure that only the users who need this incur in the space costs that comes with installing them. The con of this approach is that it requires an one time extra step to install the full support for docbook. After the installation the upgrade process is the same as a standard installation. The issue here are what it should be the standard set: # repoquery -q --requires texlive-collection-latexextra | wc -l 1358 # repoquery -q --requires texlive-collection-latexrecommended | wc -l 74 # repoquery -q --requires texlive-collection-latex | wc -l 58 So one option would be to jump from recommending texlive-collection- latexrecommended to texlive-collection-latexextra... but it implies to install more than one thousand packages (the size is small). Choices... choices... the life is made of choices. :-D Regards, -- José Abílio -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel

The issue is simple, I would like to determine what is the minimal set of latex packages required to have a working LyX version. I do not see these problems because I have all the texlive packages installed. For the Fedora package tough that is not the best scenario. For example in the spec file we have: # basic set of latex packages Recommends: texlive-collection-latexrecommended # required for file conversions Requires: ImageMagick Requires: xdg-utils Requires: ghostscript ## produce PDF files directly from DVI files Requires: tex-dvipdfmx ## convert eps to pdf Requires: tex-epstopdf ## checking the quality of the generated latex Requires: tex-chktex ## instant preview Requires: tex-dtl Requires: tex(cprotect.sty) # LaTeX packages required to compile the User's Manual Requires: tex(dvips) Requires: tex(esint.map) Requires: tex(esint.sty) Requires: tex(latex) Requires: tex(nomencl.sty) Requires: tex(simplecv.cls) Requires: tex(ulem.sty) Requires: tex(xcolor.sty) As you can see we are identifying a given set of packages in order to have a minimal working package. This is not a difficult problem but it takes time to get all the packages right. It would be nice to have an automatic way to do this but for now I settled for the manual solution.

Re: 2.4.0-beta-2 possible regression: Float inset stops instant preview functionality in Fedora 37 X86_64
I have some new information. I did a clean install of F37 on a virtual machine. Although I usually use KDE, I used the vanilla Fedora iso install which uses Gnome, so as to avoid any non-standard surprises. At first, I didn't even update the system before doing the following. I installed lyx-devel-beta2 from the jamatos repo using dnf. The install went cleanly including basic dependencies. Loading my test files into LyX I found preview inoperative, but fixed this by installing the tex-preview package and reconfiguring (possible dependency for tex-preview?). Preview now (mal)functions exactly as before: preview normal with no float inset, preview fails with float inset. But I now get some new, possibly more informative error messages. When clicking in and out of an equation to force preview I get the following messages at the terminal: Warning: Failed: dvips lyxpreviewkqkzoE.dvi ... looking for PDF Error: Failed to extract metrics info from lyxpreviewkqkzoE.log Version information for this install: Version 2.4.0-beta2 (Sunday, December 11, 2022) Qt Version (run-time): 5.15.6 on platform xcb Qt Version (compile-time): 5.15.8 OS Version (run-time): Fedora Linux 37 (Workstation Edition) Python detected: python3 -tt python --version gives: Python 3.11.0 After doing the above, I fully updated the system. LyX behavior is unchanged (still shows problem). Same error messages.

Both figure floats and table floats have the same effect. I've attached two small lyx files as an MRE. The file preview-test- float.lyx exhibits the bug; it contains an empty float inset. The otherwise identical file preview-test-no-float.lyx (with no float inset) does not. The files contain two short equations. In the example with the float, clicking in and out of the equations does not force preview, and nothing else I've tried seems to either. Running the same version here I see the preview on both files.

In the case of Fedora's package of 2.4 I am using a different different directories for library and user, respectively: /usr/share/lyx-devel and ~/.lyx-devel. This option is related with allowing to keep both versions for the moment. In the case of the OP' report this means the LyX 2.3 and 2.4 are using user's directories. Not that I think that it matters but the disclaimer goes here. -- José Abílio -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel
