What is preloaded by “mtxrun --script”?

What is preloaded by “mtxrun --script”?

Hi all,

I noticed that although mtxrun preloads some of the context libs
that doesn’t cover everything available during an ordinary mkiv
run.  What would be the canonical way to load additional libs
like “luat-ini” &c. on demand? “environment.loadluafile()”? Can
this be configured globally? Is it wise to mess with “own.libs”
in mtxrun?

Example: This snippet checks the global env for some tables.
“mtxrun --script” doesn’t find any while some of them are there
when processed as cld.

local testme = {
    "userdata", "thirddata", "moduledata", "documentdata", "parametersets",
    --"document"
}

for _,item in next, testme do
    local i = _G[item]
    if i then
        print(item, table.serialize(i))
    else
        print(item, "Nope!")
    end
end

-- Comprehensive:
--for _,k in next,table.sortedkeys(_G) do
    --print(k,_G[k])
--end

(My issue is that I’m testing the lua internals of module code
without having to startup the whole big typesetting environment.
Would be much easier if everything normally accessible from
inside an mkiv session was there as well.)

Thanks for any insights, Philipp

something

dofile(resolvers.findfile("yourfile.lua"))

but keep in mind that most of the mkiv code depends on other code and 
often they depend on functionality that is only available when we're in 
luatex mode and not in texlua mode

In this case there were two deps. I extracted the order in which
the libs are loaded by context and put it on the wiki. This isn’t a
*real* dependency tree but still it can be of help when
troubleshooting similar issues.

Thanks for the pointer, Philipp
