# crud-lang

_This is now in first-draft phase. Meaning, I just had the idea and I am jotting down very preliminary design decisions._

- an experimental language for CRUD applications (backend only though)
- Enterprise as a first-class citizen
- urls are made up directories and filenames
- a controller sourcefile is a file with the .ctl extension
- likewise
- .svc services
- .cl service clients (that call other services)
- .dao database access code (not objects)
- .qc queueconsumers
- .qp queueproducers
- .utl utilities
- there is a strict calling hierarchy. A service can not call a controller. It can only go 'down'.
- Services can not call other services, because that is the recipe for spaghetti. Refactor your logic, abstract and put lower level code in utilities.
- Utilities are allowed to call other utilities. OMG, spaghetti after all! TBD

- It is an interpreter written in rust. OMG!
- And it has everything I like in other languages
  - strictly typed
  - [] is a list
  - {} is a map
  - no objects, no inheritance
  - structs and duck typing
  - everything is an expression
  - nice iterators.
  - First class functions? Maybe...

**types**

- u32, i32
- u64, i64
- f32, f64,
- string, bool, char
- struct enum

**question**

- how to model headers
- middleware, implement later

**the example: **

- a very simple api that listens to GET /api/customers{:id} and returns a customer from the database
