Mix (build tool)

Mix (build tool) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mix (build tool) rather than just read about it. In short: Mix is a build automation tool for working with applications written in the Elixir programming language. Mix was created in 2012 by Anthony Grimes, who took inspiration from Clojure's Leiningen.

Key takeaways

Mix (build tool) belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mix (build tool) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mix (build tool) from memory before moving on to harder problems.

Reference excerpt

Mix is a build automation tool for working with applications written in the Elixir programming language. Mix was created in 2012 by Anthony Grimes, who took inspiration from Clojure's Leiningen. Soon after, Mix was merged into the Elixir programming language itself and to this day is one of the six applications that are part of the Elixir language. Mix provides functionality for creating, compiling, and testing Elixir source code and for managing dependencies and deploying Elixir applications.

Mix tasks Mix provides tasks to create, clean, build, compile, run, and test Elixir applications. For example, Mix may be used to create a new Elixir project, such as a new hello_world application. Running mix new hello_world will result in

Mix projects Mix uses the information defined in a Mix Project to compile, build, and assemble the application. By convention, this information is typically managed in an Elixir script file named mix.exs. The file may include version information, dependencies, and other configuration information.

Application As the Elixir build tool, Mix is used on applications that target the Erlang virtual machine (as opposed to the Java virtual machine or the .NET Common Language Runtime). Mix is used with web applications built on the Phoenix framework.

Worked examples

Example 1 — a first encounter with Mix (build tool)

Start with the simplest possible case. Write down what Mix (build tool) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mix (build tool) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mix (build tool) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mix (build tool)

In research: Mix (build tool) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mix (build tool) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mix (build tool) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Build automation, Compiling tools, Software engineering stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Mix (build tool) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
