<h2>Overview</h2>
|
||
<p>fddl is a small programming language inspired by various languages, designed to help learn language implementation concepts in <a href="https://rust-lang.org">Rust</a>.</p>
|
||
<p>For years, I’ve tried to learn various programming languages, and while I could master the basics, the real-world projects often eluded me. And I wouldn't know who to turn to even if I knew where to start.</p>
|
||
<p>fddl was born out of this journey. fddl is my attempt to combine the aspects I appreciate from many languages into something uniquely my own.</p>
|
||
<p>I started learning Rust and have really liked it. I've been following tutorials and the <a href="http://craftinginterpreters.com/">Crafting Interpreters</a> site as guides for this very problematic programming language.</p>
|
||
<p>I like aspects of so many programming languages, but I don't really like any of them, so I always found it hard to pick one and stick with it. But I had the same problem playing World of Warcraft, too.</p>
|
||
<p>So I, like many of you, decided to make a hobby programming language to see what may be able to be done with it. This is a brand new project as of September 2024 and I am one person.</p>
|
||
<p>The fact that I have a REPL working in this language is nothing short of amazing to me. It's fucking magic.</p>
|
||
|
||
<h2>Features</h2>
|
||
<ul>
|
||
<li><strong>Custom syntax</strong>fddl introduces unique operators and keywords to make programming more intuitive and fun (at least for me)</li>
|
||
<li><strong>Lexer</strong> currently is the only thing working. It tokenizes fddl scripts into understandable pieces of the language.</li>
|
||
<li><strong>Tilde Operator</strong> (<code>~</code> and <code>~=</code>) when something almost equals something else. I had the idea from watching a video on <a href="https://www.youtube.com/watch?v=_ZSFRWJCUY4">Non-Euclidean Doom</a>.</li>
|
||
</ul>
|
||
|
||
<h2>Getting Started</h2>
|
||
<p>Keep in mind, this is only at the lexer stage currently. It'll read your inputs and that's it.</p>
|
||
<p>To clone the repo:</p>
|
||
<pre><code class="language-bash">git clone https://git.fddl.dev/fddl/fddl.git</code></pre>
|
||
<p>To run the REPL:</p>
|
||
<pre><code class="language-bash">cargo run</code></pre>
|
||
<p>To parse a fddl script:</p>
|
||
<pre><code class="language-bash">cargo run path/to/script.fddl</code></pre>
|
||
|
||
<h2>Examples</h2>
|
||
<p>Your basic "hello, world":</p>
|
||
<pre><code class="language-rust">func main() {
|
||
print("hello, world in fddl");
|
||
}</code></pre>
|
||
<p>Defining a function inside a module, squaring a number:</p>
|
||
<pre><code class="language-rust"># This is a sample module
|
||
|
||
module math {
|
||
|
||
// Computes the square of a number
|
||
func square(x) => x ^ 2;
|
||
}
|
||
|
||
sym number = 5;
|
||
print(`The square of $number is ${math.square($number)}`);</code></pre>
|
||
<p>At least for right now. I still want to do something odd.</p>
|
||
|
||
<h2>Running the Project</h2>
|
||
<p>Make sure your project compiles and the tests pass:</p>
|
||
|
||
<pre><code class="language-bash">cargo build
|
||
cargo test
|
||
cargo run</code></pre>
|
||
<p>Again, <code>cargo run</code> only starts the REPL for testing.</p>

<h2>Goals and Projections:</h2>
|
||
<p><strong>Note:</strong> This is not a final list; it's words on paper (metaphorically) at the time of writing.</p>
|
||
<p><strong><code>Lexer</code>:</strong></p>
|
||
<ul>
|
||
<li class="task-list-item"><input type="checkbox" checked disabled> Built and tested for basic syntax and operators.</li>
|
||
<li class="task-list-item"><input type="checkbox" checked disabled> Supports single-line and documentation comments.</li>
|
||
<li class="task-list-item"><input type="checkbox" disabled> Add support for more complex syntax and features.</li>
|
||
</ul>
|
||
<p><strong><code>Parser</code>:</strong></p>
|
||
<ul>
|
||
<li class="task-list-item"><input type="checkbox" disabled> Currently a placeholder. Implement parsing for function calls, expressions, checks, literally everything.</li>
|
||
</ul>
|
||
<p><strong><code>Compiler</code>:</strong></p>
|
||
<ul>
|
||
<li class="task-list-item"><input type="checkbox" disabled> Currently a placeholder. Implement the compiler to compile parsed code.</li>
|
||
</ul>
|
||
<p><strong>Comments:</strong></p>
|
||
<ul>
|
||
<li class="task-list-item"><input type="checkbox" checked disabled> Added support for single-line and documentation comments.</li>
|
||
<li class="task-list-item"><input type="checkbox" disabled> Implement multi-line comments.</li>
|
||
<li class="task-list-item"><input type="checkbox" disabled> Implement document building comments.</li>
|
||
</ul>
|
||
<p><strong>Error Handling:</strong></p>
|
||
<ul>
|
||
<li class="task-list-item"><input type="checkbox" disabled> Replace <code>stderr</code> with a more robust error handling mechanism..</li>
|
||
</ul>
|
||
<p><strong>Testing:</strong></p>
|
||
<ul>
|
||
<li class="task-list-item"><input type="checkbox" checked disabled> Added initial <code>lexer</code> tests.</li>
|
||
<li class="task-list-item"><input type="checkbox" disabled> Expand tests to cover more syntax and edge cases.</li>
|
||
</ul>
