Hi!
I would like to use tikz to benefit of the package "pgf-soroban" I did write for LaTeX (after adapting it and before, later, to translate it to metapost).
I did try the sample program from the tikz manual, but I get an error saying that "t-pgf.tex" is not found; but it is in the tree of ConTeXt-lmtx.
How to make all the files in the distribution known to the compiler?
Note that there is currently no proper support for LMTX in PGF/TikZ.
Interesting... it seems that only a few features don't work. I regularly use pgfplots, and haven't noticed any compatibility issues in my examples.
What will be needed to add a LMTX "driver" for TikZ? Porting pgfsys- luatex.def to pgfsys-luametatex.def? Or is something else also needed?
Yes, there would have to be a pgfsys-luametatex.def and some detection code to switch the driver appropriately but that latter part is easy. I'm not too sure what is needed for the former though for LMTX. When I last looked at it about a year ago it was completely unusable with the LuaTeX driver because position tracking primitives were removed (\pdflastxpos, \pdflastypos) and box keywords had changed (\hbox dir TRT). Some catcode trickery in pgfplots also had stopped working (https://github.com/pgf-tikz/pgfplots/pull/353). As Hans mentioned in another message, the PDF resource management has changed (if I understand it correctly), so things like shadings and patterns would have to be adjusted. Cheers, Henri
