Quill was a database query prototype that I created in 2020. Laurel is my current iteration of database-y query language-y research.
Some things I was playing with:
-
Programming language improvements (https://github.com/LightAndLight/quill/blob/3532e15e4a3c7135486f706159b0841daffed153/NOTES.md#database)
- Simpler / more modern syntax
- Type checking
- Monadic sequencing of such as
inserting into tables (I currently don't endorse this)
-
Improving migrations (https://github.com/LightAndLight/quill/blob/master/DESIGN.md#migrations)
- Consistency and type checking
- View the current schema implied by a set of migrations
-
Client / server "plugin" system to support multiple backends (protocol definitions) (not sure whether I endorse this any more)
Things I was aiming for but didn't implement:
- Compile "quill" query files to language-specific code (https://github.com/LightAndLight/quill/projects/2#card-67470085, https://github.com/LightAndLight/quill/projects/2#card-36183490)
- Newtypes (https://github.com/LightAndLight/quill/projects/2#card-36183417)
- Informative migration errors (https://github.com/LightAndLight/quill/projects/2#card-36235067)
