## Motivation

Bringing emails to your 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 CLI API that
can be used either directly for the terminal or from various interfaces. It
gives users more flexibility.

## Installation

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

*See [wiki section](https://github.com/soywod/himalaya/wiki/Installation) for
more information.*

## Configuration

```toml
# ~/.config/himalaya/config.toml

name = "Your full name"
downloads_dir = "/abs/path/to/downloads"

# Himalaya supports the multi-account
# Each account should be inside a TOML section
[gmail]
default = true
email = "my.email@gmail.com"

imap_host = "imap.gmail.com"
imap_port = 993
imap_login = "p.durant@gmail.test.com"
imap_passwd_cmd = "pass show gmail"

smtp_host = "smtp.gmail.com"
smtp_port = 487
smtp_login = "p.durant@gmail.test.com"
smtp_passwd_cmd = "pass show gmail"

[posteo]
name = "Your overriden full name"
downloads_dir = "/abs/path/to/overriden/downloads"
email = "my.email@posteo.net"

imap_host = "posteo.de"
imap_port = 993
imap_login = "my.email@posteo.net"
imap_passwd_cmd = "security find-internet-password -gs posteo -w"

smtp_host = "posteo.de"
smtp_port = 487
smtp_login = "my.email@posteo.net"
smtp_passwd_cmd = "security find-internet-password -gs posteo -w"

# [other account]
