FAQs

Does debugger.lua support remote debugging for applications running on separate machines or embedded systems?

debugger.lua is primarily designed for in-process debugging within the same Lua environment. While it doesn't offer built-in remote debugging protocols, developers could potentially build a custom remote interface on top of its core functionalities.

Are there any performance considerations or overhead when using debugger.lua in a production environment?

As a pure Lua solution, debugger.lua introduces some overhead, especially when stepping through code or inspecting large data structures. It's generally recommended for development and testing environments rather than continuous use in performance-critical production code.

Can debugger.lua be used with specific Lua frameworks or game engines like LÖVE2D or OpenResty?

Yes, debugger.lua is designed to be highly embeddable and pure Lua, making it compatible with most Lua 5.x and LuaJIT 2.x environments, including those within frameworks like LÖVE2D or platforms like OpenResty, as long as standard Lua functionalities are available.
