            What is the best practice of passing reference counted C++ objects to Lua?
            Asked 2021-Jun-16 at 02:17

            I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc meta-method, but how to implement the increasing side?

            Is it proper&enough to just increase refcount every time before adding the object to Lua stack?

            Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc meta-method? This seems ugly as if something wrong with the Lua execution and the __gc is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.

            In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT section of XS Map, and decrease refcount at destroyer.

            I assume you have implemented two Lua functions in C: inc_ref_count(obj) and dec_ref_count(obj)

            Simple lua_yield in C not resuming correctly from Lua
            Asked 2021-Jun-13 at 17:37

            I'm just starting to delve into lua coroutines with C and I'm having a problem with what I think should be the simplest example I can come up with.

            The C:

            ...

            ANSWER

            Answered 2021-Jun-13 at 16:58

            lua_yield is a C function, and C does not have a mechanism to magically jump back into a function that has halted. lua_yield uses the C standard library longjmp function to arbitrarily jump out of the function that called it. But it can't come back.

            So what happens is that your C function yields, exiting the function and returning control to the Lua code that called coroutine.resume. The resume was successful, so true is printed. You then resume the coroutine again, which begins execution at the site in Lua code that called the C function that yielded. That code then exits the coroutine normally. Since the resume was also successful, true is printed again.

            But the coroutine is now exhausted and therefore cannot be resumed.

            C functions don't have a clean way to be "resumed". Indeed, the Lua 5.1 documentation explicitly states:

            This function should only be called as the return expression of a C function, as follows:

            Pandoc loading images but not latex files from input subfolder
            Asked 2021-Jun-12 at 06:57

            I've got a latex document that I publish as a pdf, but I need to share it with reviewers in Word .docx format. I've got some images and a bunch of graphs in tikz format in a separate .tex files in a figures subfolder. I've defined input@path{{figures/}} so that I don't have to put the path into each \input{blah.tex} call. This works just fine when I publish the document as a pdf, but when I try to use pandoc to create the docx I get a [WARNING] Could not load include file error for the .tex files, though the images load fine.

            As far as I can tell, pandoc should be able to load files from subfolders and the input@path should set it up (this post discuses how to use pandoc parameters to define the input@path).

            I'm sure this is some basic lack of understanding on my part, but here's a minimum non-working example:

            Pandoc does not support the \input@path parameter. You could open a feature request here.

            I suggest to use TeX to compile the TikZ packages into proper graphics, e.g. with the method described in this Q&A, then use \renewcommand to change \input to \includegraphics, which pandoc will understand. This will also allow to make use of the --resource-path option.
