I do not think that this is possible or would be overly complicated.
In fact lua itself doesn't do this itself. However if you know how
please suggest a way to do this. There was a lua lint program
somewhere that may be useful.
Try this simple program:
a = math.sin(1)
b = math.si(2)
$ ./lua5.1.exe precomp_test.lua
d:\wxCVS\wxLua\wxLua\bin\lua5.1.exe: precomp_test.lua:2: attempt to
call field 'si' (a nil value)
stack traceback:
precomp_test.lua:2: in main chunk
[C]: ?
It doesn't check that I've mistyped "math.sin" for line 2 until it's run.
However try this:
a = math.sin(1)
b = 1math.si(2)
$ ./lua5.1.exe precomp_test.lua
d:\wxCVS\wxLua\wxLua\bin\lua5.1.exe: precomp_test.lua:2: malformed
number near '1math'
It does check for gross syntax errors.
