Overview

Loop Language

Documentation | Website
A dynamic type-safe general purpose programming language


Note: currently Loop is being re-written into Rust. Meaning that while this change is happening not all features of Loop are implemented.

In this repository, you will find the lexer, parser, compiler and virtual machine.

Get started (usage)

  1. Download a pre-built binary from the releases section for your platform
  2. Run ./loop to start the REPL environment or
  3. Run ./loop FILENAME.lp to run a specific file.

Get Started (development)

  1. Make sure you have Rust installed
  2. Clone the repository git clone https://github.com/looplanguage/loop
  3. Enter the repository cd loop
  4. Run the command cargo run
  5. The Loop shell should now popup

Comments

    Add comments to code

    Currently most of Loop does not have comments explaining what functions actually do. To use Rust's docgen we want to add comments to code.

    An example of a good comment is this:

    // Adds two numbers together and returns the result
/// # Example
/// ```
/// // Value will be 300
/// let value = add_numbers(100, 200);
/// ```
fn add_numbers(a: i32, b: i32) -> i32 {
    a + b
}

    Comments can contain markdown with examples, as seen above. We use the following standard for these comments: https://github.com/rust-lang/rfcs/blob/master/text/1574-more-api-documentation-conventions.md#appendix-a-full-conventions-text

    (The same as the Rust STD library).

  • Implement the code explainer

    Implement the code explainer

    When this function is called, it prints a very beginner friendly explenation of the code. Example 1:

    explain {
    var f = fn(x) { x + 2 }
}

    Print:

    Functions ' f ' has a parameter called ' x ', when ' f ' is called the value of ' x ' is being upped by 2 and that value is returned

    Example 2:

    explain {
    var x = true;
    if ( x ) { x = false; }
}

    Print:

    A variable called ' x ' is created with the value: ' true '. Then there is an if statement. If the condition of the if statement equals ' true ', ' x ' gets assigned the value of ' false '.

  • JIT-conditionals

    JIT-conditionals

    This PR makes if-then-else work inside JIT-ted functions.

    A few caveats:

    • Chaining doesn't work (if-then-else if-else if-else-if-else etc)
      • Internally this should be optimized to a switch instead
    • It's only possible for a simple expression (& one parameter only)
    • You can not use blocks, only a single expression that must return either an integer or float

  • Go to Gitlab for issues

    Go to Gitlab for issues

    DO NOT CREATE ISSUES IN GITHUB

    We moved to Jira for our issues.

    If you are an open-source contributor, and thus do not have acces to our Jira. You then need to create an issue in GitLab. We will review the issue and if important enough we will move it to Jira. Bugs will always be put in Jira. Features request might not, if we do not think it is a good idea to implement it in Loop.

    We do not recommend working on a feature request if it is not accepted into Jira. It will probably be rejected.
