Re: Finding and loading Lua files

[Ivan Kolev <ikolev@...>]

Yes, actually the only thing required is a properly set up LUA_PATH
environment variable. So you can distribute tools with the following
installation instructions:

- Install (unzip with subdirectories) all tools in a common directory,
e.g. C:\Program Files\Lua

- Associate the .lua extension with your lua executable using the
following command line:
C:\Program Files\Lua\lua.exe %*

- Set the environment variable LUA_PATH to
?;?.lua;C:\Program Files\Lua\?.lua

Which seems simple enough. Then the only requirement that remains is to
install each tool in a folder with some fixed name, so each tool could
do
  require "tools/someTool"
or
  require "thisTool/subModule"
Of course, fixed names could possibly lead to name clashes, as we know,
but that should happen very rarely, and could be avoided by installing
different sets of tools into different subfolders, and adding each to
LUA_PATH.
