Hi,
Those prefix are added internally by the Lua
interpreter. iuplua_dostring/iuplua_dobuffer simply call luaL_loadbuffer.
If I add that prefix it will not find the file or incorrectly interpret the
string.
The problem in debugger I already reported to the Lua team (in the Lua
list), but I got no result.
============================================================
In *lua_Debug *documentation, "source" description states that if the
function was defined in a string then "source" is that string.
I may misunderstood it but it seems that in this case source is
the chunkname, not the string. If chunkname is not used in load, then
chunkname is the string, which results in what is described. But if
chunkname is used then "source" is not the string where the function was
defined.
I tested in Lua 5.1, 5.2 and 5.3 and they all behave the same.
So, is there a problem in the documentation or in the debugger?
Assuming it is just a problem in the documentation, during debug how can
we retrieve the original string given the chunkname?
============================================================
If anyone has a light on this please let me know.
Best,
Scuri
