Package Graph

[hbcarlos]

A graph to visualize packages #83 The dependencies are not correct we need to get the dependencies of the packages to show them.

I'm reusing the code from jupyterlab-plugin-graph

[jtpio]

The dependencies are not correct we need to get the dependencies of the packages to show them.

Maybe there are some parts that can be ported from the previous backend: https://github.com/mamba-org/mamba-navigator/blob/master/server/list_and_query.py

[hbcarlos]

I improved the graph and add it to the package manager. For now, we can open the dependencies graph for a package by clicking on his version (we should change that later)

[hbcarlos]

I applied all the changes except for:

Should we handle directly here the fact that mamba will be able to render the graph but not conda? What happen for not installed packages?

Take a look and let me know if there is something wrong.

[hbcarlos]

I'll look at the test tonight or tomorrow.

Great work @hbcarlos

I have two requests regarding the style:

• Is it possible to color the node of the selected package differently to highlight it?
• Could you set the font size for the node to --jp-ui-font-size0? The current 8px is quite small.

[hbcarlos]

Sure, it's done. I'll do a new commit.

Regarding:

The idea is to add an icon in the toolbar above the packages list (it will be absent if mamba is not available - or disabled with a title advertising mamba 😉 ). On click on the button, this would open the dependency panel (not sure if on the right of the package list is a good place or if it needs to be a separated panel to allow positioning and resize by the user).

Do you want to do it in this PR or open a new one?

[hbcarlos]

Thanks, @fcollonval. I completely agree with those suggestions. You can commit them and merge the PR.
