I recently found out how powerful the iex tool is for documentation.
This is the general form of getting detailed documentation:
This is the start of a long series about the modules that you get out of the box.
1> h Module.function_name/arity
This returns the documentation on this specific function in the specific module.
I also found that typing a capital letter and tab expands the known modules.
Here is an introduction to what you get out of the box with iex:
|A||Access||Key based access to structures.|
|Agent||Simple abstraction around state|
|Application||Working with applications and their callbacks|
|ArgumentError||This is a struct used for errors.|
|ArithmeticError||This is a struct used for errors.|
|Atom||Convenience functions for working with atoms.|
Translating Elixir/Erlang terms:
An application is equivalent of a windows DLL, something that you compose a system out of. A typical application would be a logging system.
Atoms are a non-garbage collected resource. They make convenient aliases to global things.
Doing the same with :a gives the erlang modules
|a||application||Generic OTP Application|
|application_controller||Kernel supplied application controller|
|application_master||Kernel supplied application master.|
Responsible for knowing the topmost
|application_starter||Responsible for starting applications in |
a defined order
|array||Array structure, fixed or extensible|
|atomics||Provides atomic operations using |
|auth||Erlang network authentication server |
