Squish source maps

[Alexander Gladysh <agladysh@...>]

Hi, list!

We use Squish[1] as a tool to pack and minify a bunch of Lua source code files.

It works nicely, but error messages and stack traces are, obviously, a
bit hard to comprehend.

Did anyone implement something akin to JavaScript source maps[2] for
Squish (preferably supporting mapping line numbers as well)?

I guess it would require some changes to how minified code is
generated — to place each function call on a separate line, but it
should not affect resulting code size.

Best,
Alexander.
