This repository provides a tool to convert OCaml types to a Markdown format that can be visualized using the Markmap extension in Visual Studio Code (VSCode).

1. Install Markmap Extension

   • Open VSCode.
   • Go to the Extensions view by clicking the Extensions icon in the Activity Bar on the side of the window or by pressing Ctrl+Shift+X.
   • Search for "Markmap" and install the Markmap extension from the VSCode Marketplace.

2. Prepare Your OCaml Types

   • Create a separate file named type.ml to store your OCaml types.

3. Generate Markdown File

   • Run the ocaml_to_md.py script. This script will read the types.ml file and generate a corresponding type.md file.
   • You can then open the type.md file in VSCode and use the Markmap extension to visualize the types.

Suppose you have the following OCaml types defined in type.ml:

(* Enumerated type to represent different system calls *)
type system_call =
  | CreateProcess
  | TerminateProcess
  | SendMessage
  | ReceiveMessage
  | AllocateMemory
  | FreeMemory

(* Enumerated type to represent different states of a process *)
type process_state =
  | Ready
  | Running
  | Waiting
  | Terminated

(* Record type to represent a process in the system *)
type process = {
  pid: int;
  state: process_state;
  memory: int; (* Amount of memory allocated to the process *)
  message_queue: string list; (* Queue of messages for IPC *)
}

(* Record type to represent the microkernel *)
type microkernel = {
  processes: process list;
  system_calls: (system_call * process) list;
}

Running the ocaml_to_md.py script will generate a type.md file with a Markdown representation of these types. Open type.md in VSCode and use the Markmap extension to view a mind map of your OCaml types.

We can easily expand/un-expand the map.
