Visual Studio Code: extensions

Showing installed extentions

On the command line: 
C:\> code --list-extensions --show-versions
In the GUI: ctrl+shift+p or F1, then type show i[nstalled extensions].

Silencing extension recommendations

It's possible to configure VS Code to not show extension recommendations in settings.json by setting extensions.ignoreRecommendations to true.

Extension management on the command line

Extensions can be configured with command line options:
--extension-dir <dir> Configure root path for extensions
--list-extensions
--show-versions Used along with --list-extensions
--install-extension (<extension-id> | <extension-vsix-path>)
--uninstall-extension (<extension-id> | <extension-vsix-path>)
--enable-proposed-api (<extension-id>)
For example, explicit folding and VSCodeVim can be installed in one go like so: 
code --install-extension zokugun.explicit-folding --install-extension vscodevim.vim

yarn package

code --install-extension vim-<MAJOR>.<MINOR>.<PATCH>.vsix --force
