Please provide a hex package for aleppo
It would be wonderful if a hex package for aleppo would be available. Since there are no dependencies it should be really easy :)
option not to expand to instant lambda application?
some people use macros to inline stuff without duplicating code or to inline checks in guards, from what I see in expand_macro_fun and trying the example below it seems all macro invocations expand to a fun definition and invocation, I think epp doesn't do this? if it doesn't then shouldn't be a way to ask not to expand to this fun wrapping behaviour?
-define(V(Line, Type, Val), {val, Line, Type, Val}).
-define(Int(Line, Val), ?V(Line, integer, Val)).
int(Line, Val) -> ?Int(Line, Val).
should aleppo expand macros that expand to macro calls?
with some macros definitions like this:
-define(V(Line, Type, Val), {val, Line, Type, Val}).
-define(Int(Val), ?V(_, integer, Val)).
shouldn't aleppo call process_tree until the result equals the result of the last call? that is expand until the expansion doesn't result in a tree with macros?

{error,{{6,24},erl_parse,["syntax error before: ",["_X"]]}}I can offer a PR soon for FUNCTION_NAME if interested!
maps's error not throw
If Account is maps. And "Account:id()" not throw any error.
It should be:
exception error: bad argument
in function apply/3
called as apply(#{key => value},id,[])
No error and i can't debug my code.
"-" will be Syntax error
The old version can not support maps.
And the latest version can not use "-" like "util:unixtime() - calendar:time_to_seconds(time())."
"-" will be syntax error. "*", "/" and "+" are fine.
There is another discussion: ChicagoBoss/ChicagoBoss#520
problem with defines
I'm still trying to write hello-world using chicagoboss[1].
-module(mytest).
-export([start/0]).
-define(USE_BOSS_WEB_TEST, true).
-ifdef(USE_BOSS_WEB_TEST).
-define(TEST_GET_REQUEST, boss_web_test:get_request).
-endif.
start() ->
?TEST_GET_REQUEST("/some_uri", [], [], []).
Looks simple. But aleppo crashes on compile:
