a wepback loader using comment to do precompilation work. ###install npm install --save-dev comment-loader. ###why we need it? conditional code is not allowed in es6+, this means you cannot use if-else or switch-case structure to enable/disable some modules. however if some precompilation work can be performed before webpack pass your code to babel or other es transformers, the problem can be solved easily. macro like c-style macro can be a way to do all this. ###what different? some macro loaders can already be found on github or npm. however, they usually cause some side-effects. using macro directly will break the syntax which will cause big problem if the loader is not available. here i use the hack on comments and babylon parser to detect the define macro. using comments is a way to lower the side-effects as many as possible, though it still bother ide sometimes. comments are not force to be at the beginning of the line, since babylon can always detect ast correctly. another important reason why i use babylon is that i hope the comments can do more in future. maybe i'll let loader support simple
