Overview of Elixir Code Evaluator
The Elixir Code Evaluator is a specialized tool designed to execute and evaluate Elixir code snippets in real-time, providing immediate feedback on results or errors. It serves both as a development aid for Elixir programmers and as a learning tool for those seeking to understand and refine their Elixir skills. Its core function is to take user input—usually a block of Elixir code—execute it, and return the computed result along with any standard output (such as `IO.puts`). The evaluator is capable of running simple expressions, testing small functions, and validating logic quickly without requiring a full Elixir development environment. A key design feature is its ability to handle Elixir's functional programming patterns, and it's tailored to deliver results that match Elixir’s syntactical and operational standards. For example, a user can input a snippet like `Enum.sum([1, 2, 3, 4, 5])`, and the evaluator will return `15`, which is the result of summing the list. This makes the evaluator highly useful for testing ideas or debugging small pieces of code without setting up a local Elixir environment.
Core Functions of Elixir Code Evaluator
Evaluating simple expressions and functions
Example
If a user submits `Enum.sum([1, 2, 3, 4, 5])`, the evaluator returns the result `15`.
Scenario
This is useful when a developer needs to quickly test a built-in Elixir function, such as verifying that an `Enum` operation is working as expected.
Capturing and returning standard output
Example
The code snippet `IO.puts("Hello World")` will return the result `:ok` along with the output `Hello World\n`.
Scenario
In situations where a user wants to check if output-generating functions like `IO.puts` or `IO.inspect` are working properly, they can verify the correctness of side effects directly through the evaluator.
Testing custom module definitions
Example
The code `defmodule Math do def add(a, b), do: a + b end Math.add(10, 5)` will return the result `15`.
Scenario
Developers who need to quickly validate a custom module or function can use the evaluator to check the correctness of their definitions without deploying or testing in a full development environment.
Target Users of Elixir Code Evaluator
Elixir developers
Elixir developers, from beginners to experts, will find the Elixir Code Evaluator helpful for testing snippets of code, validating function outputs, or debugging issues without setting up a full development environment. It offers a quick feedback loop that aids in the iterative process of writing and refining code.
Students and educators
This tool is ideal for students learning functional programming concepts or educators who are teaching Elixir in an academic or training context. It provides an immediate, interactive way to test code examples and demonstrate key concepts in a controlled environment.
Steps to Use Elixir Code Evaluator
1
Visit aichatonline.org for a free trial without login. No ChatGPT Plus is required to use the tool.
2
Prepare your Elixir code. Make sure it is syntactically correct and self-contained, as the evaluator only supports valid Elixir code.
3
Upload your code directly or paste it into the text input field. You can also upload files that contain Elixir code to be evaluated.
4
Click on the ‘Evaluate’ button to execute the code. Wait for the results, which include the computed output and any printed messages from the code.
5
Review the results. If there is an error, verify your code for issues such as undefined functions or missing variables, and try again.

Common Questions about Elixir Code Evaluator
What types of Elixir code can be evaluated?
Elixir Code Evaluator supports any valid Elixir syntax, including built-in functions, custom modules, and basic HTTP requests using libraries like HTTPoison. The code must be self-contained, with all necessary variables and values defined.
Can I evaluate multi-file Elixir projects?
No, Elixir Code Evaluator currently supports single-file execution only. You can include multiple modules and functions in one file, but dependencies on external files or libraries must be handled within the code itself.
How do I handle external HTTP requests in my code?
You can use HTTPoison or similar libraries to make HTTP requests. However, the number of requests should be kept minimal to avoid exhausting server resources, as there is a timeout limit for external requests.
What is the maximum execution time for code?
The evaluator enforces a strict time limit of around 5 seconds for code execution. If the code exceeds this time, it will be terminated and return a timeout error to prevent server overload.
What types of errors will the evaluator catch?
The evaluator will catch and report syntax errors, undefined function errors, and execution timeouts. If the code attempts to perform malicious operations, it will be blocked and a relevant error message will be returned.
