*Himalaya CLI is written in [Rust](https://www.rust-lang.org/), and relies on [cargo features](https://doc.rust-lang.org/cargo/reference/features.html) to enable or disable functionalities. Default features can be found in the `features` section of the [`Cargo.toml`](https://github.com/pimalaya/himalaya/blob/master/Cargo.toml#L18).*
|
|
|
|
## Installation
|
|
|
|
*The `v1.0.0` is currently being tested on the `master` branch, and is the prefered version to use. Previous versions (including GitHub beta releases and repositories published versions) are not recommended.*
|
|
|
|
### Pre-built binary
|
|
|
|
Himalaya CLI `v1.0.0` can be installed with a pre-built binary. Find the latest [`pre-release`](https://github.com/pimalaya/himalaya/actions/workflows/pre-release.yml) GitHub workflow and look for the *Artifacts* section. You should find a pre-built binary matching your OS.
|
|
|
|
### Cargo (git)
|
|
|
|
Himalaya CLI `v1.0.0` can also be installed with [cargo](https://doc.rust-lang.org/cargo/):
|
|
|
|
```bash
|
|
$ cargo install --git https://github.com/pimalaya/himalaya.git --force himalaya
|
|
```
|
|
|
|
### Other outdated methods
|
|
|
|
These installation methods should not be used until the `v1.0.0` is finally released, as they are all (temporarily) outdated:

<summary>Pre-built binary</summary>
|
|
|
|
Himalaya CLI can be installed with a prebuilt binary:
|
|
|
|
```bash
|
|
# As root:
|
|
$ curl -sSL https://raw.githubusercontent.com/pimalaya/himalaya/master/install.sh | sudo sh
|
|
|
|
# As a regular user:
|
|
$ curl -sSL https://raw.githubusercontent.com/pimalaya/himalaya/master/install.sh | PREFIX=~/.local sh

```
|
|
|
|
These commands install the latest binary from the GitHub [releases](https://github.com/pimalaya/himalaya/releases) section.
|
|
|
|
*Binaries are built with [default](https://github.com/pimalaya/himalaya/blob/master/Cargo.toml#L18) cargo features. If you want to enable or disable a feature, please use another installation method.*

|
|
<summary>Sources</summary>
|
|
|
|
Himalaya CLI can be installed from sources.
|
|
|
|
First you need to install the Rust development environment (see the [rust installation documentation](https://doc.rust-lang.org/cargo/getting-started/installation.html)):
|
|
|
|
```bash
|
|
$ curl https://sh.rustup.rs -sSf | sh
|
|
```
|
|
|
|
Then, you need to clone the repository and install dependencies:
|
|
|
|
```bash
|
|
$ git clone https://github.com/pimalaya/himalaya.git
|
|
$ cd himalaya
|
|
$ cargo check
|
|
```
|
|
|
|
Now, you can build Himalaya:
|
|
|
|
```bash
|
|
$ cargo build --release
|
|
```
|
|
|
|
*Binaries are available under the `target/release` folder.*
|
|
</details>
|
|
|
|
## Configuration
|
|
|
|
Just run `himalaya`, the wizard will help you to configure your default account.
|
|
|
|
You can also manually edit your own configuration, from scratch:
|
|
|
|
- Copy the content of the documented [`./config.sample.toml`](./config.sample.toml)
|
|
- Paste it in a new file `~/.config/himalaya/config.toml`
|
|
- Edit, then comment or uncomment the options you want
|
|
|

<summary>Proton Mail (Bridge)</summary>
|
|
|
|
When using Proton Bridge, emails are synchronized locally and exposed via a local IMAP/SMTP server. This implies 2 things:
|
|
|
|
- Id order may be reversed or shuffled, but envelopes will still be sorted by date.
|
|
- SSL/TLS needs to be deactivated manually.
|
|
- The password to use is the one generated by Proton Bridge, not the one from your Proton Mail account.
|
|
|
|
```toml
|
|
[accounts.proton]
|
|
email = "example@proton.me"
|
|
|
|
backend = "imap"
|
|
imap.host = "127.0.0.1"
|
|
imap.port = 1143
|
|
imap.encryption = false
|
|
imap.login = "example@proton.me"
|
|
imap.passwd.raw = "<bridge-imap-p@ssw0rd>"
|
|
|
|
message.send.backend = "smtp"
|
|
smtp.host = "127.0.0.1"
|
|
smtp.port = 1025
|
|
smtp.encryption = false
|
|
smtp.login = "example@proton.me"
|
|
smtp.passwd.raw = "<bridge-smtp-p@ssw0rd>"
|
|
```
|
|
|
|
Keeping your password inside the configuration file is good for testing purpose, but it is not safe. You have 2 better alternatives:
|
|
|
|
- Save your password in any password manager that can be queried via the CLI:
|
|
|
|
```toml
|
|
imap.passwd.cmd = "pass show proton"
|
|
```
|
|
|
|
- Use the global keyring of your system (requires the `keyring` cargo feature):
|
|
|
|
```toml
|
|
imap.passwd.keyring = "proton-example"
|
|
```
|
|
|
|
Running `himalaya configure -a proton` will ask for your IMAP password, just paste the one generated previously.

<summary>Gmail</summary>
|
|
|
|
Google passwords cannot be used directly. There is two ways to authenticate yourself:
|
|
|
|
### Using [App Passwords](https://support.google.com/mail/answer/185833)
|
|
|
|
This option is the simplest and the fastest. First, be sure that:
|
|
|
|
- IMAP is enabled
|
|
- Two-step authentication is enabled
|
|
- Less secure app access is enabled
|
|
|
|
First create a [dedicated password](https://myaccount.google.com/apppasswords) for Himalaya.
|
|
|
|
```toml
|
|
[accounts.gmail]
|
|
email = "example@gmail.com"
|
|
|
|
folder.alias.inbox = "INBOX"
|
|
folder.alias.sent = "[Gmail]/Sent Mail"
|
|
folder.alias.drafts = "[Gmail]/Drafts"
|
|
folder.alias.trash = "[Gmail]/Trash"
|
|
|
|
backend = "imap"
|
|
imap.host = "imap.gmail.com"
|
|
imap.port = 993
|
|
imap.login = "example@gmail.com"
|
|
imap.passwd.cmd = "pass show gmail"
|
|
|
|
message.send.backend = "smtp"
|
|
smtp.host = "smtp.gmail.com"
|
|
smtp.port = 465
|
|
smtp.login = "example@gmail.com"
|
|
smtp.passwd.cmd = "pass show gmail"
|
|
```
|
|
|
|
Keeping your password inside the configuration file is good for testing purpose, but it is not safe. You have 2 better alternatives:
|
|
|
|
- Save your password in any password manager that can be queried via the CLI:
|
|
|
|
```toml
|
|
imap.passwd.cmd = "pass show gmail"
|
|
```
|
|
|
|
- Use the global keyring of your system (requires the `keyring` cargo feature):
|
|
|
|
```toml
|
|
imap.passwd.keyring = "gmail-example"
|
|
```
|
|
|
|
Running `himalaya configure -a gmail` will ask for your IMAP password, just paste the one generated previously.
|
|
|
|
### Using OAuth 2.0
|
|
|
|
This option is the most secure but the hardest to configure. It requires the `oauth2` and `keyring` cargo features.
|
|
|
|
First, you need to get your OAuth 2.0 credentials by following [this guide](https://developers.google.com/identity/protocols/oauth2#1.-obtain-oauth-2.0-credentials-from-the-dynamic_data.setvar.console_name-.). Once you get your client id and your client secret, you can configure your Himalaya account this way:
|
|
|
|
```toml
|
|
[accounts.gmail]
|
|
email = "example@gmail.com"
|
|
|
|
folder.alias.inbox = "INBOX"
|
|
folder.alias.sent = "[Gmail]/Sent Mail"
|
|
folder.alias.drafts = "[Gmail]/Drafts"
|
|
folder.alias.trash = "[Gmail]/Trash"
|
|
|
|
backend = "imap"
|
|
imap.host = "imap.gmail.com"
|
|
imap.port = 993
|
|
imap.login = "example@gmail.com"
|
|
imap.oauth2.client-id = "<imap-client-id>"
|
|
imap.oauth2.auth-url = "https://accounts.google.com/o/oauth2/v2/auth"
|
|
imap.oauth2.token-url = "https://www.googleapis.com/oauth2/v3/token"
|
|
imap.oauth2.pkce = true
|
|
imap.oauth2.scope = "https://mail.google.com/"
|
|
|
|
message.send.backend = "smtp"
|
|
smtp.host = "smtp.gmail.com"
|
|
smtp.port = 465
|
|
smtp.login = "example@gmail.com"
|
|
smtp.oauth2.client-id = "<smtp-client-id>"
|
|
smtp.oauth2.auth-url = "https://accounts.google.com/o/oauth2/v2/auth"
|
|
smtp.oauth2.token-url = "https://www.googleapis.com/oauth2/v3/token"
|
|
smtp.oauth2.pkce = true
|
|
smtp.oauth2.scope = "https://mail.google.com/"
|
|
|
|
# If you want your SMTP to share the same client id (and so the same access token)
|
|
# as your IMAP config, you can add the following:
|
|
#
|
|
# imap.oauth2.client-id = "<client-id>"
|
|
# imap.oauth2.client-secret.keyring = "gmail-oauth2-client-secret"
|
|
# imap.oauth2.access-token.keyring = "gmail-oauth2-access-token"
|
|
# imap.oauth2.refresh-token.keyring = "gmail-oauth2-refresh-token"
|
|
#
|
|
# imap.oauth2.client-id = "<client-id>"
|
|
# imap.oauth2.client-secret.keyring = "gmail-oauth2-client-secret"
|
|
# imap.oauth2.access-token.keyring = "gmail-oauth2-access-token"
|
|
# smtp.oauth2.refresh-token.keyring = "gmail-oauth2-refresh-token"
|
|
```
|
|
|
|
Running `himalaya configure -a gmail` will complete your OAuth 2.0 setup and ask for your client secret.

## FAQ
|
|
|
|
<details>
|
|
<summary>How to compose a message?</summary>
|
|
|
|
An email message is a list of **headers** (`key: val`) followed by a **body**. They form together a template:
|
|
|
|
```eml
|
|
Header: value
|
|
Header: value
|
|
Header: value
|
|
|
|
Body
|
|
```
|
|
|
|
***Headers and body must be separated by an empty line.***
|
|
|
|
### Headers
|
|
|
|
Here a non-exhaustive list of valid email message template headers:
|
|
|
|
- `Message-ID`: represents the message identifier (you usually do not need to set up it manually)
|
|
- `In-Reply-To`: represents the identifier of the replied message
|
|
- `Date`: represents the date of the message
|
|
- `Subject`: represents the subject of the message
|
|
- `From`: represents the address of the sender
|
|
- `To`: represents the addresses of the receivers
|
|
- `Reply-To`: represents the address the receiver should reply to instead of the `From` header
|
|
- `Cc`: represents the addresses of the other receivers (carbon copy)
|
|
- `Bcc`: represents the addresses of the other hidden receivers (blind carbon copy)
|
|
|
|
An address can be:
|
|
|
|
- a single email address `user@domain`
|
|
- a named address `Name <user@domain>`
|
|
- a quoted named address `"Name" <user@domain>`
|
|
|
|
Multiple address are separated by a coma `,`: `user@domain, Name <user@domain>, "Name" <user@domain>`.

|
|
### Plain text body
|
|
|
|
Email message template body can be written in plain text. The result will be compiled into a single `text/plain` MIME part:
|
|
|
|
```eml
|
|
From: alice@localhost
|
|
To: Bob <bob@localhost>
|
|
Subject: Hello from Himalaya
|
|
|
|
Hello, world!
|
|
```
|
|
|
|
### MML boby
|
|
|
|
Email message template body can also be written in MML. The MIME Meta Language was introduced by the Emacs [`mml`](https://www.gnu.org/software/emacs/manual/html_node/emacs-mime/Composing.html) ELisp module. Pimalaya [ported it](https://github.com/pimalaya/core/tree/master/mml) in Rust.
|
|
|
|
A raw email message is structured according to the [MIME](https://www.rfc-editor.org/rfc/rfc2045) standard. This standard produces verbose, non-friendly messages. Here comes MML: it simplifies the way email message body are structured. Thanks to its simple XML-based syntax, it allows you to easily add multiple parts, attach a binary file, or attach inline image to your body without dealing with the MIME standard.
|
|
|
|
For instance, this MML template:
|
|
|
|
```eml
|
|
From: alice@localhost
|
|
To: bob@localhost
|
|
Subject: MML simple
|
|
|
|
<#multipart type=alternative>
|
|
This is a plain text part.
|
|
<#part type=text/enriched>
|
|
<center>This is a centered enriched part</center>
|
|
<#/multipart>
|
|
```
|
|
|
|
compiles into the following MIME Message:
|
|
|
|
```eml
|
|
Subject: MML simple
|
|
To: bob@localhost
|
|
From: alice@localhost
|
|
MIME-Version: 1.0
|
|
Date: Tue, 29 Nov 2022 13:07:01 +0000
|
|
Content-Type: multipart/alternative;
|
|
boundary="4CV1Cnp7mXkDyvb55i77DcNSkKzB8HJzaIT84qZe"
|
|
|
|
--4CV1Cnp7mXkDyvb55i77DcNSkKzB8HJzaIT84qZe
|
|
Content-Type: text/plain; charset=utf-8
|
|
Content-Transfer-Encoding: 7bit
|
|
|
|
This is a plain text part.
|
|
--4CV1Cnp7mXkDyvb55i77DcNSkKzB8HJzaIT84qZe
|
|
Content-Type: text/enriched
|
|
Content-Transfer-Encoding: 7bit
|
|
|
|
<center>This is a centered enriched part</center>
|
|
--4CV1Cnp7mXkDyvb55i77DcNSkKzB8HJzaIT84qZe--
|
|
```

<summary>How to debug Himalaya CLI?</summary>
|
|
|
|
The simplest way is to use `--debug` and `--trace` arguments.
|
|
|
|
The advanced way is based on environment variables:
|
|
|
|
- `RUST_LOG=<level>`: determines the log level filter, can be one of `off`, `error`, `warn`, `info`, `debug` and `trace`.
|
|
- `RUST_SPANTRACE=1`: enables the spantrace (a span represent periods of time in which a program was executing in a particular context).
|
|
- `RUST_BACKTRACE=1`: enables the error backtrace.
|
|
- `RUST_BACKTRACE=full`: enables the full error backtrace, which include source lines where the error originated from.
|
|
|
|
Logs are written to the `stderr`, which means that you can redirect them easily to a file:
|
|
|
|
```
|
|
RUST_LOG=debug himalaya 2>/tmp/himalaya.log
|
|
```

<summary>How the wizard discovers IMAP/SMTP configs?</summary>
|
|
|
|
All the lookup mechanisms use the email address domain as base for the lookup. It is heavily inspired from the Thunderbird [Autoconfiguration](https://udn.realityripple.com/docs/Mozilla/Thunderbird/Autoconfiguration) protocol. For example, for the email address `test@example.com`, the lookup is performed as (in this order):
|
|
|
|
1. check for `autoconfig.example.com`
|
|
2. look up of `example.com` in the ISPDB (the Thunderbird central database)
|
|
3. look up `MX example.com` in DNS, and for `mx1.mail.hoster.com`, look up `hoster.com` in the ISPDB
|
|
4. look up `SRV example.com` in DNS
|
|
5. try to guess (`imap.example.com`, `smtp.example.com`…)
