How well do ConTeXt (lua)module for other users?

How well do ConTeXt (lua)module for other users?

[Jaroslav Hajtmar]

Hello ConTeXist.

I have done the module (for context), which is entirely written in Lua 
(ConTeXt definitions are done through Lua too).

I wonder how it can be loaded into ConTeXt file. Have I to use the 
beginning of the file:
\startluacode
   dofile ("my-module.lua")
\stopluacode

to loading the module? I would like to use \usemodule [my-module.lua], 
but there is a problem, that code must be inside \startluacode ... 
\stopluacode environment.
But when I put my luacode into \startluacode ... \stopluacode into 
my-module.mkiv file, then I have a problem with catcodes inside strings 
defining by  [[  ... ]].

Or must be module consists of two separate files (my-module.lua and 
my-module.mkiv)? Must I to load the Lua module file (my-module.lua)  
into ConTeXt module file (my-module.mkiv) by command 
\ctxlua{dofile("my-module.lua ");} and then load module file 
(my-module.mkiv) into my user file by command \usemodule[my-module]?

Is there something like \useluamodule[....] or  
\usemodule[anyluaswitch][modulefile] ???

How to proceed in these cases? I find it inappropriate to divide the 
module into two separate files.

Thanx Jaroslav

It's lua , so
require("my-module.lua")
also works

Use \usemodule:

<example>
\startbuffer[test]
function test(argument)
    context.quotation(argument)
end

interfaces.definecommand {
    name = "test",
    arguments = {
        { "content", "string" },
    },
    macro = test,
}
\stopbuffer

\savebuffer[test][p-test.lua]

\usemodule[test]

\starttext
\test{Hello}
\stoptext
</example>

Wolfgang

Great ... that's exactly what I needed ... Thanks very much Wolfgang.
It can be somewhere on similar techniques to read more? Just links to 
some sample files to the dissected ...

Thanks a lot
Jaroslav

You should always read Hans bet announcements where he often mentions new features and sometimes gives examples.

Thanx Wolfgang.

Is there a solid practice of naming modules? I noticed that the names 
appear modules including introductory letters "p" or "t" ... You also 
used the name p-test.lua. What does it mean? How to correctly name the 
module, or what other elements should it include?

Best regards
Jaroslav

p is for private i.e. never part of the distribution
t is for third party i.e. can be installed on demand
