To implement #line support [1], I went into the Proto struct and embedded a filename index into the top bits of Proto.lineinfo. Then I changed Proto.source to be an array. I didn't keep the code, unfortunately, and I've been kicking myself since.On Wed, Oct 19, 2011 at 1:52 PM, Mike Pall<mikelu-1110@mike.de> wrote:The troublesome part are not the line numbers -- this can be handled with the existing per-prototype line-number table (LuaJIT actually compresses this table internally). But you'd really want to allow multiple source filenames, too. That's where it gets somewhat expensive.Ah, right in general we would not have a simple one-to-one file translation. But a restricted form might still be useful enough to implement.
I do not know LuaJIT's internals as well, so I don't know what it would take over there.
In any case, this is very doable and without much difficulty. -Josh [1] - http://lua-users.org/lists/lua-l/2011-08/msg00910.html
