Comments Break Parsing Logic

[ddhorstman]

Describe the bug
It would seem that the presence of comments in my files is confusing aurora. In my org, we like to use comments as dividers to make our files easier to navigate, like so:

//--------------------------------------------------------------------------------------------------//

But the presence of a single //- sequence causes aurora to crash.

To Reproduce

1. Install aurora.
2. Pick the Author and Book schemas from README.md, and set up aurora.config.json` to combine them.
3. Add //- anywhere in either file.
4. Run aurora

Expected behavior
The two schemas are combined into a single schema

Actual Behavior
The following error is printed:

    / \     _   _   _ __    ___    _ __    __ _ 
   / _ \   | | | | | '__|  / _ \  | '__|  / _` |
  / ___ \  | |_| | | |    | (_) | | |    | (_| |
 /_/   \_\  \__,_| |_|     \___/  |_|     \__,_|

I can't seem to recreate this issue. Can you paste in the schema you are using?

[cmd-johnson]

I'm encountering that same issue. It occurs every time I'm using comments before defining a model:

• Works:

  model ModelA {
    // Comment
    id Int @id
  }

• Fails:

  // Comment
  model ModelA {
    id Int @id
  }

Both using Aurora 1.3.3 running with node v16.13.0 on linux, with the following config:

{
  "files": [
    "./modelA.prisma"
  ],
  "output": "./schema.prisma"
}

Comments before datasource, generator and enum definitions work fine:

// Comment
datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

// Comment
generator client {
  provider = "prisma-client-js"
}

// Comment
enum TestEnum {
  TEST
}
