Description

This feature adds a plugin system to meshroom.
It also allows to install and run new nodes using containerization tools, such as conda and docker.

Features list

v1

• Install button in the ui
• Install from local folder
• Install from git
• Camelify code
• Add support for pipelines
• New 'build status' for nodes that are building their environment
• .json to customize plugin install
• Support multiple env per plugin
• Documentation to create plugins
• Node uninstallation
• Catalog logic
• PipNode to install pip packages in meshroom's python
• PythonVirtualEnvNode taking requirements.txt

v2

• Changing the logic from env class to env attribute

• Added badge and warning to build
• Access to meshroom within envs

v3

Implementation remarks

The logic is in meshroom/core/plugin.py .
It defines a new node classes to run python code in environments/containers using meshroom_compute.
Added bandit file to not test the shell call errors in codefactor.
Uses the CI en var to skip the tests on CI.

Future needed work: ui part to list/uninstall catalog, multiples envs per node, button to delete env

Could it be great to have "Delete Environment" button ? Like the "Delete Data"

added in todos for next version. Could be added to the "manage installed plugins" page, alongside the "un-install plugin" button
