Why is the LUA_PATH behaviour of dofile() not equivalent to require()?
I don't like to switch between two ways of accessing files e.g:
require( 'Lib/Lua/Library.lua')
dofile('/usr/local/apache/htdocs/'..'Lib/Lua/Test/dofile/Dummy.lua')
I think its easier to understand, better to read, less errors...
require('Lib/Lua/Library.lua')
dofile('Lib/Lua/Test/dofile/Dummy.lua')
I have done it and don't see negative aspects. Please let me know why do
you think this should not be done. By the way: I like the very
interesting Receiver() function mechanism.
do
local Flag,Vararg
local Receiver=function(Intercept,...) Flag,Vararg = Intercept,arg end
local Function=dofile
function dofile(File)
Receiver(pcall(Function,File))
if Flag==false then
local Path,Argument = LUA_PATH
if type(Path)~='string' then
Path=os.getenv('LUA_PATH') or './?.lua'
end
for Path in string.gfind(Path,'[^;]+') do
Argument=string.gsub(Path,'%?',File)
Receiver(pcall(Function,Argument))
if Flag then break end
end
end
return(unpack(Vararg))
end
end
