Motivation

Bringing emails to the terminal is a pain. The mainstream TUI, (neo)mutt, takes time to configure. The default mapping is not intuitive when coming from the Vim environment. It is even scary to use at the beginning, since you are dealing with sensitive data!

The aim of Himalaya is to extract the email logic into a simple (yet solid) CLI API that can be used either directly from the terminal or UIs. It gives users more flexibility.

Installation

curl -sSL https://raw.githubusercontent.com/soywod/himalaya/master/install.sh | sh

See the wiki section for other installation methods.

Configuration

# ~/.config/himalaya/config.toml

name = "Your full name"
downloads-dir = "/abs/path/to/downloads"
signature = "Regards,"

[gmail]
default = true
email = "your.email@gmail.com"

imap-host = "imap.gmail.com"
imap-port = 993
imap-login = "your.email@gmail.com"
imap-passwd-cmd = "pass show gmail"

smtp-host = "smtp.gmail.com"
smtp-port = 487
smtp-login = "your.email@gmail.com"
smtp-passwd-cmd = "security find-internet-password -gs gmail -w"

See the wiki section for all the options.

[Service]
ExecStart=/usr/local/bin/himalaya idle
