If I load a lua file from a module using \registerctxluafile{file}{1.001} or \ctxloadluafile{file} How can I be sure the file was in fact loaded? Can I make ConTeXt halt and issue an error in this case? Cheers, André Caldas.
Hey André,

The related tracker output is quite comprehensive: \enabletrackers[resolvers.locating] \ctxloadluafile{sometest} it does not make Context terminate on fail, though.
Can I make ConTeXt halt and issue an error in this case?
the macros you cite don’t offer this behavior but you can easily write a wrapper for the file loader: % macros=mkvi \def\strictload[#fname]{% \directlua{ local success = environment.loadluafile[[#fname]] if not success then print[[unrecoverable error: could not load file #fname]] os.exit(1) end }% } \starttext \strictload[unknown] \stoptext Hth Philipp

Hello, Philipp!

Nice! Thank you. In my case, it was not being loaded because I had syntax errors in the lua file. The file was found, but not loaded. I guess it is a very good reason to halt! Cheers, André Caldas.
Hello,
I'm using this if loading failure is not fatal:
----
DoFile = function(fn)
return pcall(function() return dofile(fn) end)
end
DoFile("MyFile.lua") -- instead of 'dofile("MyFile.lua")'
----
You can play with handling error code (http://www.lua.org/manual/5.1/manual.html#pdf-pcall):
----
DoFile = function(fn)
local suc, res = pcall(function() return dofile(fn) end)
if suc then return res
else
-- Your handling code to come here
end
end
----
Best regards,
Lukas
