preloading tikz and listings

[kohlhase]

There has been a fix in Bruce's LaTeXML branch which (I hope) allows to preload all of listings.sty.ltxml and tikz.sty.ltxml with all their dependencies. This should speed up conversion by a large factor, so I had hoped that this would find its way into the KWARC branch, but we still seem to be re-loading the dependencies every time.
@dginev could you please clarify?

It seems that lmh still uses the generic stex-modules.opt profile, that should change as well.

You can preload listings with all its dependencies but not tikz. As long as you are using --preload, listings now auto-magically loads all language definition files, so that you never need to load anything during the actual conversion runs.

We need something similar for tikz, but preloading all of tikz will be rather slow. There are many libraries and each takes tens of seconds to load with LaTeXML.

[kohlhase]

In what way is tikz.sty so different from listings.sty? Is it the libraries?

But if I understand correctly, preloading the core tikz should be possible (i.e. all that is loaded by \usepackage{tikz}). And then we need something for the libraries that are loaded with \usetikzlibrary they should be preloaded separately (if they are needed).

[dginev]

Well, tikz does a lot more than listings, and it is much larger, making it a lot slower to load. Also, the raw TeX loading is a much bigger component for tikz than it is for listings.

You can already do --preload=tikz.sty to get the core library, and it should be possible to do something like --preload='literal:\usetikzlibrary{foo} to get the libraries loaded on the side, but I haven't tried that.

@kohlhase can this be closed, too?
