<h2>Overview</h2>
|
|
||||||
<p>fddl is a small, experimental programming language, built in Rust, designed to explore language implementation concepts. It's a blend of ideas from various languages but remains unique, with its own syntax and quirks.</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. Rust, however, clicked for me, and fddl was born out of this journey.</p>
|
|
||||||
|
|
||||||
<p>I like aspects of many programming languages, but I didn’t fully enjoy any of them, which made it difficult to commit to one. So, like many others, I decided to create my own hobby programming language.</p>
|
|
||||||
|
|
||||||
<h2>Features</h2>
|
|
||||||
<ul>
|
|
||||||
<li>Custom syntax with unique operators and keywords</li>
|
|
||||||
<li>Documentation comments using <code>#</code>, similar to Rust's style</li>
|
|
||||||
<li>Lexer and parser built from scratch</li>
|
|
||||||
</ul>
|
|
||||||
|
|
||||||
<h2>Getting Started</h2>
|
|
||||||
<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 run 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;
|
|
||||||
}
|
|
||||||
|
|
||||||
define $number := 5;
|
|
||||||
print(`The square of $number is ${math.square($number)}`);
|
|
||||||
</code></pre>
|
|
||||||
<p>(At least for now.)</p>
|
|
||||||
|
|
||||||
<h2>Notes and Next Steps</h2>
|
|
||||||
<ul>
|
|
||||||
<li class="task-list-item"><input type="checkbox" checked disabled> Added first new set of tokens and features, added the first <code>lexer</code> tests.</li>
|
|
||||||
<li class="task-list-item"><input type="checkbox" disabled> <code>parser</code> module is a placeholder.</li>
|
|
||||||
<li class="task-list-item"><input type="checkbox" disabled> <code>interpreter</code> module is a placeholder.</li>
|
|
||||||
<li class="task-list-item"><input type="checkbox" disabled> Implement a more robust error handling mechanism instead of using <code>stderr</code>.</li>
|
|
||||||
<li class="task-list-item"><input type="checkbox" disabled> Implement string interpolation (backticks with <code>$variable</code>).</li>
|
|
||||||
<li class="task-list-item"><input type="checkbox" disabled> Continue to expand tests to cover all new syntax and features.</li>
|
|
||||||
<li class="task-list-item"><input type="checkbox" checked disabled> Made a basic website.</li>
|
|
||||||
</ul>
|
|
||||||
|
|
||||||
<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</code></pre>
