This file can be compiled using elixirc: This will generate a file named Elixir.Math.beam containing the bytecode for the defined module. If we start iex again, our module definition will be available (provided that iex is started in the same directory the bytecode file is in): Elixir projects are usually organized into three directories:
One may also ask,
In Elixir, the module is starting block. Elixir is a functional programming language, which means that everything happens in functions. Elixir creators decided that Elixir’s function must have a module. Let's create a string from number 46 using the Integer module that comes with Elixir.
Consequently, Multiple uses of @dialyzer will accumulate instead of overriding previous ones. Specifies an external resource for the current module. Sometimes a module embeds information from an external file. This attribute allows the module to annotate which external resources have been used.
In addition,
We could use require to tell Elixir you’re going to use macros from other module. The slight difference with import is that it allows using macros, but not functions from the specified module: If we attempt to call a macro that is not yet loaded Elixir will raise an error.
Similarly,
Modules are way how to group Elixir functions in meaningful groups. This post is part of the functional language series. In Elixir, the module is starting block. Elixir is a functional programming language, which means that everything happens in functions.
