lager_truncation_size does not work

[coolchevy]

option {lager_truncation_size, 1024}
does not work on current master

Data was truncated on default (?DEFAULT_TRUNCATION) size

[Vagabond]

It works if I use it like this:

erlc -pa ebin +'{lager_truncation_size, 100}' test.erl

With a file like this:

-module(test).

-export([start/0]).

-compile([{parse_transform, lager_transform}, {lager_truncation_size, 100}]).

start() ->
  lager:info("~p", [string:copies("hello wrld", 20)]).

But note that the -compile option inside the module does not work (don't ask me why).

I can't find info fun in lager module. Where is it? May be you use not master branch?
Thanks

[Vagabond]

It is created via a parse transform.

Thank you, really it works by lager:info, but truncation doesn't work if you call error_logger:info_msg. Message truncated by DEFAULT_TRUNCATION

1> test:start().
11:28:49.318 [info] "hello..."
ok
11:28:49.318 [info] DBG: "hello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrldhello wrld"

can you fix it?

[Vagabond]

Right, those messages are covered by a different truncation limit, which is not (currently) configurable.

The transform could check the attributes in the AST for lager_truncation_size if it can't find it in the options. This would allow lager_truncation_size to be specified in the -compile attribute in the module. It is confusing that it doesn't work, though that is nothing to do with lager :)
