-- Example of how to use debug.lua to debug profiles in a pure lua environment.
|
||
|
|
-- It makes it easy to manually set tags, run the way processing and check the result.
|

|
|
--
|
||
|
|
-- To use, make a copy of this file and gitignore your copy. (If you use the name ndebug.lua,
|
||
|
|
-- it's already gitignored.)
|
||
|
|
--
|
||
|
|
-- You run your copy via the lua command line:
|
||
|
|
-- > cd profiles
|
||
|
|
-- > lua5.1 debug.lua
|
||
|
|
--
|
