Configuration Options
Sup will generate a complete configuration file (~/.sup/config.yaml) with default settings for all the options the very first time you run it. If you've been using Sup for a while, you may be missing some options that have been added since your config.yaml file was generated.
Some config options that warrant mention. A complete list can be found in sup.rb, circa line 312.(Look for "def load_config filename")
Configuring multiple accounts to work intelligently with the Reply function has its own section: MultipleAccountsAndReply
:confirm_no_attachments
If true, and you use words like "attach", "attachment", or "attached" in your email and don't have any attachments, Sup will prompt you before sending. This will be true when a default config.yaml is generated, but are considered false if not explicitly specified.
:confirm_top_posting
If true, and you top-post, Sup will tell you that you are a bad person and will prompt you to confirm that before posting. This will be true when a default config.yaml is generated, but are considered false if not explicitly specified.
:ask_for_cc
:ask_for_bcc
:ask_for_subject
These determine which fields you're asked for when composing and (except for subject) forwarding messages.
:continuous_scrolling
Continuous scrolling is enabled when this is true. By default this is false; continuous scrolling can be intensive and slow down sup when viewing long threads and lists.
