I have some projects based on LyX 2.2.3 that I want to work on and I don't want to update to new. However, I also have projects based on 2.3 and I can't edit those with old LyX.
Liviu Andronic worked out a way for this to be possible a few years ago, but I cannot find documents about it. I wish I could have old and new lyx installed at same time, to easily run one or the other. I've tried to do this by installing 2.3.1 from the Ubuntu package and then compiling 2.2.3 from source and installing off the path, but then I found the 2 versions should not share a user configuration folder. After using 2.3.1 and allowing it to revise ~/.lyx, then lyx 2.2.3 cannot start. Error like this: $ ./lyx Warning: Could not read configuration file ---------------------------------------- Error while reading the configuration file preferences. Please check your installation. So obviously I need to be more graceful, separate config folders. I thought about building a new Debian package "lyx223". I'm pretty sure that's what I think Liviu did. For me that was a fail because the deb packaging code for the lyx project has a lot of hard coded folders like /usr/share/lyx, so it is not too easy to rebuild a package to use alternate folders. If you have advice about this, I would be glad to hear it. -- Paul E.
