Setup Instructions for HEROKU CLI Autocomplete ---

1) Add the autocomplete env var to your zsh profile and source it
$ printf "$(heroku autocomplete:script zsh)" >> ~/.zshrc; source ~/.zshrc                             # これを実行

NOTE: After sourcing, you can run `$ compaudit -D` to ensure no permissions conflicts are present

2) Test it out, e.g.:
$ heroku <TAB>                 # Command completion
$ heroku apps:info --<TAB>     # Flag completion
$ heroku apps:info --app=<TAB> # Flag option completion

Visit the autocomplete Dev Center doc at https://devcenter.heroku.com/articles/heroku-cli-autocomplete

Enjoy!

zshに設定をパスを書き込む

上記のコマンド実行結果に記載された設定を実施する。

% printf "$(heroku autocomplete:script zsh)" >> ~/.zshrc; source ~/.zshrc

自動補完機能の確認

heroku lまで打ち込んで「TAB」を押すと補完機能が働き、下記のように表示されるはず。

$ heroku l
labs           -- list experimental features
labs:disable   -- disables an experimental feature
labs:enable    -- enables an experimental feature
labs:info      -- show feature info
leave          -- remove yourself from a team app
local          -- run heroku app locally
local:run      -- run a one-off command
local:version  -- display node-foreman version
lock           -- prevent team members from joining an app
logs           -- display recent log output
