DEPS = gunThis chapter describes how to start and stop the Gun application.
Before Gun can be used it needs to be in Erlang’s ERL_LIBS path variable.
If you use erlang.mk or a similar build tool, you only need to specify
Gun as a dependency to your application and the tool will take care
of downloading Gun and setting up paths.
With erlang.mk this is done by adding gun to the DEPS variable
in your Makefile.
DEPS = gunGun is an OTP application. It needs to be started before you can use it.
1> application:ensure_all_started(gun). {ok,[ranch,crypto,cowlib,asn1,public_key,ssl,gun]}
You can stop Gun using the application:stop/1 function, however
only Gun will be stopped. This is the equivalent of application:start/1.
The application_ensure_all_started/1 function has no equivalent for
stopping all applications.
application:stop(gun).
An OTP release starts applications automatically. All you need
to do is to set up your application resource file so that Gun can
be included in the release. The application resource file can be
found in ebin/your_application.app, or in src/your_application.app.src
if you are using a build tool like erlang.mk.
The key you need to change is the applications key. By default
it only includes kernel and stdlib. You need to add gun to
that list.
{applications, [
kernel,
stdlib,
gun
