…eScriptToLua#1445) Lua's require() uses dots as path separators, so a file at Foo.Bar/index.lua is unreachable via require("Foo.Bar.index") since Lua looks for Foo/Bar/index.lua. Expand dotted path segments into nested directories in the emit output, and emit a diagnostic when this expansion causes output path collisions.

While this is a possible solution, wouldn't it be simpler (and the output more reasonable) if we were to just find/replace periods with e.g. underscores in the output file names? |
… nested directories

Could you also add a test where you're including a file like "Foo.Bar.ts", or maybe "foo.test.ts" since that was mentioned in the issue, rather than only directories with dots
