By convention, most Built-In Functions (BIFs) and all predefined types are included in this module. Some of the BIFs and all of the predefined types are viewed more or less as part of the Erlang programming language and are auto-imported. Thus, it is not necessary to specify the module name. For example, the calls atom_to_list(erlang) and erlang:atom_to_list(erlang) are identical. Auto-imported BI
View Source Introduction Purpose "Premature optimization is the root of all evil" (D.E. Knuth) Efficient code can be well-structured and clean, based on a sound overall architecture and sound algorithms. Efficient code can be highly implementation-dependent code that bypasses documented interfaces and takes advantage of obscure quirks. Ideally, your code only contains the first type of efficient c
View Source Expressions In this section, all valid Erlang expressions are listed. When writing Erlang programs, it is also allowed to use macro and record expressions. However, these expressions are expanded during compilation and are in that sense not true Erlang expressions. Macro and record expressions are covered in separate sections: PreprocessorRecords Expression Evaluation All subexpression
Elixir v1.6.5 Kernel View Source This module is the entry point of the Elixir programming language. It provides the default functions and macros Elixir imports into your environment. Those can be directly invoked in your code without the module name: iex> is_number(13) true These functions and macros can be skipped or cherry-picked via the Kernel.SpecialForms.import/2 macro. For instance, if you w
