I'm moving toward Lua only scripting, backed by Rust only system commands (at least in model space for now). From that approach, I intend to solve this Shell use case with https://github.com/BurntSushi/fst https://github.com/BurntSushi/fst and any needed Lua syntax extensions, like http://lua-users.org/wiki/StringInterpolation http://lua-users.org/wiki/StringInterpolation , http://lua-users.org/wiki/VarExpand http://lua-users.org/wiki/VarExpand , etc. So far, I have some stacks of notes on Rust replacements and some links to Lua dialogues on similar (failed) attempts for a new shell. If you have any more points of interest or a drive to implement it, cool.
