+# DynamicC
+A syntactically nice language that compiles to C99
+
+Built using JetBrains MPS, Code is written in a *projectional editor*.
+
+## Features
+
+### Modern Syntax
+Syntax is heavily inspired by Kotlin, and does not aim for compatibility with C.
+
+### Safe Memory Access
+Todo;
+
+### Cleaned Up Types
+C99 comes with so many unclear types, it's actually insane to keep track of. We use instead `uint8..128`, `int8..128`, `byte8..128` and `float32..128` for most things.
+
+### Rudimentary Classes
+I promise, these are optional. In many cases it can be useful if a struct can posess a function that does stuff on it, so it
+essentially just creates a function that takes the struct as an additional parameter. I don't really plan to add inheritance or
+any of the more advanced features though.
+
+### Strong and weak types
+Coming from TypeScript, it was especially important to me to be able to define types aliases that are incompatible (`strong type`) 
+and type aliases that can be used interchangeably (`weak type`).
+```
+strong type ReturnCode from int8
+
+var a: ReturnCode = 0
+val b: int8 = 1
+
+// Error: ReturnCode can't be assigned to int8
+a = b
+
+// Use this if you want to assign it anyways
+a = b as int8
+```
+
+### Multi Assignments
+I saw this feature in Crystal, and wanted it here.
+```
+int a: int8 = 1;
+int b: int8 = 2;
+
+a, b = b, a
+```
+
+### Null Safety
+Similar to Kotlin, you can't assign a variable the value `null` unless you mark it nullable:
+```
+// Error: a can't be null
+val a: int8 = null
+
+// If you need it to be null, use this instead
+val b: int8? = null
+```
