WIP click CLI wrapper around normal CLI

[Crivella]

Enabling

For now manually pip install:

• pip install click

• pip install rich-click

• Extract all the parameters from EasyBuildOptions and use them to generate a CLI with click

• Uses click + rich_click to have a fancier looking CLI

Autocomplete

From click docs add the following to the .bashrc or venv activation script.

eval "$(_EB2_COMPLETE=bash_source eb2)"

Alternatively see aiida-core EC to activate it as a module

Advantages

• Nicer looking
• Automatic integration and autocomplete with bash zsh fish shells

TODO

• Implement/convert more types for better autocompletion
• Better integrate logging with rich

Maybe

• Rewrite the CLI logic to use click natively and divide the commands in subgroups to have an easier to read help

How would this look like

eb2 --help

Error

Normal build run
