.net - Embedded a Lua interactive prompt window in C# -

i tried provide script features in c# app. after searches, lua , luainterface looks reasonable way it. embedding lua vm in c# code, can load lua script , process methods defined in c# class without problems.

however, wonder there way not execute lua script file in c# program, have lua interactive prompt in program? can type commands , see returns immediately.

any hint should start work on helpful!

best regards

lua's debug module contains basic interactive console: debug.debug() (the lua manual suggests this module should used debugging).

if doesn't meet needs, it's easy enough implement 1 yourself. if write in lua itself, absolute bare bones console be:

while true    io.write("> ")    loadstring(io.read())() end 

that'll crash on either syntax or runtime error. less minimal version, captures (and ignores) errors:

while true    io.write("> ")    local line = io.read()    if not line break end -- quit on eof?    local chunk = loadstring(line)    if chunk       pcall(chunk)    end end 

this enhanced displaying syntax errors (second return value loadstring on failure), runtime errors (second return value pcall on failure), return values evaluated code ([2..n] return values pcall on success), etc.

if want really fancy, can allow people enter multi-line statements. @ src/lua.c in source distro see how done.
