Lua环境注册表？

Question

I'm trying to read the windows registry to figure out what scripting environments are installed and where the stand alone interpreter executables are available.

When I did python, for example, I searched for

HKEY_LOCAL_MACHINE/SOFTWARE/Python/PythonCore/InstallPath

This gives me the install path for the python executable for the environment, this allows me to find if I have python 2.7, 3, etc and where those exes are.

I'm looking for something similar for Lua for windows.

I must use the registry for this search.

Answer 1

What Nicol said. You will be better served by scanning PATH against the list of known executables (but even that is not a guarantee as many of my local installs are not in PATH). Still, I think there is a better chance of finding those scripting engines that don't leave their traces in the registry. Or maybe use a combination of mechanisms.

Answer 2

Lua does not have an install path. Lua does not have an installation . Lua is not like Python, with an installer that puts everything in one specific place and sets up registry and PATH entries and such.

The standalone interpreter does not have a mechanism to query its location. If you're interested in learning the Lua version, you can always check the _VERSION variable field. But other than that, no, there is no mechanism for doing what you want.
