Bundler plugin that can be installed system-wide (`gem install bundler-install_dash_docs`) or on a per-project basis (`bundle plugin install bundler-install_dash_docs`). Once installed, primary command is `bundle install_dash_docs install` This will read your Gemfile.lock, and use the Dash.app (v3.1.0 and later) custom url scheme `dash-install:` to request that Dash.app install the matching documentation for each gem at the specific version. It currently takes ~2 seconds per gem, so its a long process for large projects. I'd love to do more, but Dash.app does not yet support anything more interesting (removing older versions? updating a search profile?).
