It would be great if the work being done for smart code-assist in the Koneki LDT project could be integrated with LuaInspect. These two tools complement each other very well. LDT uses type inference via MetaLua to provide context sensitive code completion in the editor obtained from LDoc style commented code. See here for the announcement of code-assist in LDT: http://lua-users.org/lists/lua-l/2012-02/msg00536.html.
The original author of MetaLua is involved in the LDT project and some of the work they've done in MetaLua for code-assist is on the MetaLua git hub (probably the luaeclipse branch): https://github.com/fab13n/metalua/branches
Do you have any plans on doing something like this?
