Nim import from project root directory

How to import a module from project root directory in Nim?

Instead of doing so:

import ../../http
import ../seq

I'd like to import my module using absolute path relative to the project root directory, like this:

import src/http
import src/utils/seq

How can I achieve that?

Solution

  • This can be done by giving nim the project root directory as a new search path:

    nim c --path:'.' project.nim

    And you can drop in a config.nims at the project root with the content --path:"." to automate this.

    So, with a directory tree like

    .
├── config.nims
├── project.nim
└── src
    ├── http.nim
    └── utils
        ├── dir
        │   └── editing_me.nim
        └── seq.nim

    The editing_me.nim module can then import http and seq as src/http and src/utils/seq. You will still be able to import them with relative paths, too.
