Lua Notes

confirming code generation

With --print-code nelua writes to stdout instead of a cache/explicit file. As the different sections of the code are clearly signposted, you can use sed to pull out those sections.

$ nelua --print-code -i 'local function longname(a: *[0]cstring) <nodce> end' | sed -n '/DECLARATIONS/,/DEFINITIONS/p'
/* ------------------------------ DECLARATIONS ------------------------------ */
typedef char** nlcstring_arr0_ptr;
static void eval_R3JFTdrFKg9_longname(nlcstring_arr0_ptr a);
/* ------------------------------ DEFINITIONS ------------------------------- */

Or grep:

$ nelua --print-code -i 'local function longname(a: *[0]cstring) <nodce> end' | grep -A1000 DECLARATIONS
/* ------------------------------ DECLARATIONS ------------------------------ */
typedef char** nlcstring_arr0_ptr;
static void eval_R3JFTdrFKg9_longname(nlcstring_arr0_ptr a);
/* ------------------------------ DEFINITIONS ------------------------------- */
void eval_R3JFTdrFKg9_longname(nlcstring_arr0_ptr a) {
}
int main(int argc, char** argv) {
  return 0;
}

And although the Lua generator isn't maintained, it's still around:

$ nelua -g lua --print-code -i 'local function longname(a: *[0]cstring) <nodce> end'
local function longname(a)
end
