nvim-luadev

This plugins set up a REPL-like environment for developing lua plugins in Nvim. The :Luadev command will open an scratch window which will show output from executing lua code.

Use the folllowing mappings to execute lua code:

Binding	Action
<Plug>(Luadev-RunLine)	Execute the current line
<Plug>(Luadev-Run)	in visual mode: execute visual selection
<Plug>(Luadev-RunWord)	Eval identifier under cursor, including table.attr

If the code is a expression, it will be evaluated, and the result shown with inspect.lua. Otherwise it will be executed as a block of code. A top-level return will cause the returned value to be inspected. A bare nil will not be shown.

Global print() is also redirected to the output buffer, but only when executing code via this plugin. require'luadev'.print(...) can be used to print to the buffer from some other context.

Planned features:

• autodetect expression vs statements
• Fix inspect.lua to use tostring() on userdata (done on a local copy)
• omnicompletion of global names and table attributes
• make <Plug>(Luadev-Run) a proper operator
• solution for step-wise execution of code with local assignments (such as a flag to copy local values to an env)
• tracebacks
