Erlang Language Features

In this section

• Erlang Data Types and Structures
  Use Erlang lists, tuples, maps, records, binaries, bitstrings, and arrays with their performance trade-offs.
• Pattern Matching and Guards in Erlang
  Write Erlang function clauses, case expressions, and guard sequences that make control flow explicit and safe.
• Erlang Enumerations with the `lists` Module
  Use Erlang `lists` functions for mapping, filtering, folding, partitioning, sorting, and pipeline-friendly transformations.
• Erlang List Comprehensions and Generators
  Build Erlang lists with comprehensions, generators, filters, pattern matches, and readable transformation pipelines.
• Erlang Coding Style and Conventions
  Apply Erlang naming, formatting, module layout, comments, and documentation conventions for maintainable team code.
• Erlang Shell (REPL) for Interactive Development
  Use the Erlang shell for quick experiments, module loading, process inspection, debugging, and runtime verification.
• EDoc Documentation in Erlang
  Document Erlang modules, functions, types, and APIs with EDoc so code remains easier to maintain and review.
• Erlang Error Handling and Exceptions
  Handle Erlang exceptions, exits, throws, supervision boundaries, and failure signals in fault-tolerant code.
• Erlang Typespecs and Dialyzer Static Analysis
  Add Erlang typespecs and Dialyzer checks to find contract mistakes, unreachable code, and type inconsistencies.
• Erlang Build Tools with Rebar3 and Erlang.mk
  Use Rebar3 and Erlang.mk to structure Erlang projects, compile code, manage dependencies, and automate tasks.
• Managing Dependencies with Hex in Erlang Projects
  Manage Erlang dependencies with Hex, version constraints, package publishing, lock discipline, and update review.
• Erlang Versioning and Release Management
  Manage Erlang application versions, releases, semantic versioning, deployment consistency, and Rebar3 release workflows.
• Erlang Testing with EUnit and Common Test
  Test Erlang modules and systems with EUnit, Common Test, fixtures, assertions, suites, and CI-friendly workflows.
• Erlang Debugging with `dbg`, `observer`, `redbug`, and `etop`
  Diagnose Erlang runtime issues with tracing, process inspection, scheduler visibility, and production-safe debugging tools.
• Profiling and Performance Monitoring Tools in Erlang
  Profile Erlang code and runtime behavior with measurement tools that expose CPU, process, memory, and scheduler bottlenecks.
• Erlang Code Formatting with `erlfmt`
  Use `erlfmt` to keep Erlang code formatting consistent across editors, reviews, commits, and CI checks.
• Erlang Code Organization
  Organize Erlang modules, applications, supervision trees, tests, and shared utilities for maintainable systems.
• Advanced Macros and Metaprogramming in Erlang
  Use Erlang macros and metaprogramming carefully for compile-time abstraction without hiding control flow or contracts.
