Lua is designed for the following typical situation:
1. Big complicated C program wants to provide customization:
default setting of user options, user-supplied extra features etc,
2. Instead of inventing a new DSL for that purpose, Lua is provided,
preferably by including all its source code rather than relying on
a user's own installation.
As done by e.g. Love2D (via callbacks) and LuaTeX (by allowing direct
Lua is also pretty good for little standalone utilities that extend the
experience of command-line programming. Shebang programs,
Lua is not particularly brilliant at taking over from Bash as one's main
scripting language for system applications. It is not in the running with
Ruby and Python as the final solution for those who want to do what
Perl can but just can't come to grips with Perl.
Unfortunately the Hammer Principlie makes us want to use Lua for
everything. And it sure is a Swiss Army hammer. But it's still a hammer.
