[erlang-questions] escript and dependencies

[Brandon Clark]

File globbing, i.e. the '*', is a feature of your login shell, not escript.
 If I run this:

$ erl -pa _rel/lib/*/ebin


...the shell expands the '*' before launching erl.  The command that is
actually run is this:

$ erl -pa _rel/lib/cowboy-0.10.0/ebin _rel/lib/cowlib-0.6.2/ebin
_rel/lib/crypto-3.4/ebin _rel/lib/hello_cowboy-1.0/ebin
_rel/lib/kernel-3.0.1/ebin _rel/lib/ranch-0.10.0/ebin
_rel/lib/stdlib-2.1/ebin


There may be an elegant way to perform the expansion inside your script but
I don't know what it is.  I usually rely on the quick-and-dirty solution of
running:

$ echo -pa _rel/lib/*/ebin


Then I copy and paste the output into the script:

#!/usr/bin/env escript

%% -*- erlang -*-

%%! -pa _rel/lib/cowboy-0.10.0/ebin _rel/lib/cowlib-0.6.2/ebin
_rel/lib/crypto-3.4/ebin _rel/lib/hello_cowboy-1.0/ebin
_rel/lib/kernel-3.0.1/ebin _rel/lib/ranch-0.10.0/ebin
_rel/lib/stdlib-2.1/ebin


-module(democtl).
