Generate the lock file outside the platform

[joaopalmeiro]

Hi! 👋

First of all, thank you so much for this project!

I was reading the documentation to see what I need to do to set up a GitHub repo. While reading about the lock file, a question came to mind: is there a way to generate the lock file beforehand, outside of the platform, so that all the files are in the repo before creating the link? Is it possible to create it with conda-lock?

Thanks!

Hi!

It's not yet possible to generate a lock outside of the platform. We rely on mambajs's lock file representation and not conda-lock.

We are thinking of providing a CLI to generate such lock.

Got it, thanks a lot!

[martinRenou]

It's out on PyPi! Please give it a try:

pip install mambajs

mambajs create-lock environment.yml nblink-lock.json

I'll be on my way to make a conda package for it.

Hi, @martinRenou!

Thank you very much! I've already tested it for an environment for the feedzai-altair-theme and it was a success.

I ran the tool via uv for the following environment.yml file:

uvx mambajs@0.20.1 create-lock environment.yml nblink-lock.json

name: feedzai-altair-theme-demo
channels:
  - emscripten-forge
  - conda-forge
dependencies:
  - xeus-python==0.17.6
  - altair==5.5.0
  - pip:
    - feedzai-altair-theme==2.0.0

The result was as follows:

nblink-lock.json file
