Hallo Taco,

...

Everything I read below says there should be a 'plain.mem' in the folder where you ran theat file in. If there really really isn't, then my only advise to you is to buy a less thieving operating system, as it seems this one steals your files before you can even have an admiring look at them. :-)

May be you are right that operating system steals files. We should do something against that.

I tried the same with 'mpost'. This has the advantage that one has not to adapt 'plain.mp'.

But here too, there is no 'mpost.mem' and no 'mpost.log'.

I have included a test before and after mp:finish().

Can anybody with a minimal under windows run this example? ------------------------------- \starttext % start low-level \startlua local function finder(name, mode, ftype) if mode=="w" then return name else return kpse.find_file(name,ftype) end end mp = mplib.new ( { hash_size = 100000, main_memory = 2000000, param_size = 100000, find_file = finder, ini_version = true } ) if mp then res = mp:execute("mpost") tex.print("[" .. tostring(res.status) .. "]") print(table.serialize(res)) if io.open("mpost.mem","r") then print("found") else print("nothing") end res = mp:finish() print(table.serialize(res)) if io.open("mpost.mem","r") then print("found") else print("nothing") end end \stoplua % stop low-level \stoptext -------------------------------
