Dodo is a graphical email client written in Python/PyQt5, based on the command line email swiss-army-knife notmuch.
It's main goals are to:
- offer efficient, keyboard-oriented mail reading, sorting, and composing
- give a mostly text-based email experience by default, but with HTML support a few keystrokes away
- offload as much work as possible on existing, excellent command-line tools (UNIX philosphy-style)
- be simple enough to customise and hack on yourself
This README has instructions on installation, usage, and basic configuration. For API documentation (which is also useful for configuration), check out the Read the Docs page.
As an email client, Dodo is pretty much feature-complete, but not yet extensively tested. Since it's based on notmuch, all of its features are non-destructive, so you shouldn't ever lose any email due to bugs. That being said, you might see some strange behaviour, so use at your own risk.
A lot of Dodo's design is inspired by two existing notmuch-based clients: alot and astroid.
If you have already used notmuch
for email, there's not much to do here :). If not, you'll need to set up some other programs first:
- something to check mail and sync with a local Maildir (offlineimap is the default, but others like mbsync should work fine)
- a sendmail-compatible SMTP client to send mail (msmtp is the default)
- notmuch for email searching and tagging
- w3m for translating HTML messages into plaintext
All of this is pretty standard stuff, and should be installable via your package manager on Linux/Mac/etc. If you don't know how to set these things up already, see the respective websites or the "Setting up the prerequisites" section below for a quick reference.
Dodo requires Python 3.7+ and PyQt5 5.15 or above. You can install the latest git version of Dodo and its dependencies using pip:
git clone https://github.com/akissinger/dodo.git
cd dodo
pip install .
Then, run Dodo with:
dodo
If you don't have it already, you may need to add ~/.local/bin
to your PATH
.
Dodo is configured via ~/.config/dodo/config.py
. This is just a Python file that gets eval
-ed right before the main window is shown.
Most settings have reasonable defaults (assuming your are using offlineimap/msmtp), which can be found in settings.py. The only two things that must be set for Dodo to work properly are your email address and the location of your sent mail folder. Some things you probably also want to set up are the text editor (for composing messages) and the file browser (for viewing attachments).
Here is an example config.py
, with some settings similar to the ones I use:
import dodo
# required
dodo.settings.email_address = 'First Last <[email protected]>'
dodo.settings.sent_dir = '/home/user/mail/Work/Sent'
# optional
dodo.settings.theme = dodo.themes.nord
dodo.settings.editor_command = "kitty nvim '{file}'"
dodo.settings.file_browser_command = "fman '{dir}' /home/user/Documents"
A theme is just a Python dictionary mapping some fixed color names to HTML color codes. Currently, the themes implemented in themes.py are nord
, solarized_light
and solarized_dark
. If you want more, feel free to roll your own, or (better) send me a pull request!
All of the settings of the form ..._command
are given as shell command. The editor_command
setting takes a placeholder {file}
for the file to edit and file_browser_command
takes the placeholder {dir}
for the directory to browse.
The settings above replace the default text editor (xterm -e vim
) with neovim run inside a new kitty terminal. I am also using Michael Herrmann's excellent dual-pane file manager fman instead of the default (nautilus
). With these settings, showing attachments will open fman
with a fixed directory in the right pane (/home/user/Documents
) and a directory containing the attachments on the left. A similar effect can be obtained with ranger using the multipane
view mode.
While Javascript is disabled in the HTML email viewer, you may want to set up a custom HTML sanitizer function as follows:
dodo.util.html2html = dodo.util.clean_html2html
The above function passes the HTML through the Cleaner
object of the bleach library. Note this still allows some dodgy stuff, such as calling home via embedded img
tags, so remote requests from HTML messages are disabled by default via the setting html_block_remote_requests
. Javascript is also disabled.
Key mappings can be customised by changing the dictionaries defined in keymap.py. These map a key to a pair consisting of a description string and a Python function. For the global_keymap
, this function takes the Dodo
object defined in app.py as its argument. The other maps take the relevant "local" widget (SearchView, ThreadView, ComposeView, or CommandBar).
To bind a single key, you can write something like this in config.py
:
dodo.keymap.search_keymap['t'] = (
'toggle todo',
lambda p: p.toggle_thread_tag('todo'))
or you can replace the keymap completely from config.py
, e.g.:
dodo.keymap.search_keymap = {
'C-n': ('next thread', lambda p: p.next_thread()),
'C-p': ('previous thread', lambda p: p.previous_thread()),
# ...
}
The keymaps used by Dodo are global_keymap
, search_keymap
, thread_keymap
, and command_bar_keymap
. All the keymaps except command_bar_keymap
also support keychords, which are represented as space-separated sequences of keypresses, e.g.
dodo.keymap.global_keymap['C-x C-c'] = (
'exit emacs ... erm, I mean Dodo',
lambda a: a.quit())
You can unmap a single key by deleting it from the dictionary:
del dodo.keymap.global_keymap["Q"]
Most functionality in Dodo comes from keyboard shortcuts. Press ?
to get a full list of the key mappings at any time.
Dodo has 3 different kinds of view: search views, thread views, and compose views. It opens initially with a search view with the query tag:inbox
. Pressing enter or double-clicking a thread with open that thread in the thread view. Pressing c
at any time or r
while looking at a message in the thread view will open the compose view.
In the compose view, press <enter>
to edit the message on your chosen editor. Once you save and exit, the message will be updated. Press a
to add attachments (or use the special A:
header). Press S
to send.
Since there's a lot of little bits to configure, I've also included some minimal configurations for offlineimap, msmtp, and notmuch, just to have it all in one place.
Note the offlineimap and msmtp configurations below simply read the password from a plaintext file. More secure options are available, which are explained in the respective docs.
Assuming your system configuration directory is ~/.config/
, the configuration file for offlineimap is located in ~/.config/offlineimap/config
. Here is a template for syncing one IMAP account named "Work":
[general]
accounts = Work
[Account Work]
localrepository = WorkLocal
remoterepository = WorkRemote
[Repository WorkLocal]
type = Maildir
localfolders = ~/mail/Work
[Repository WorkRemote]
type = IMAP
remotehost = (IMAP SERVER)
remoteuser = (USER NAME)
remotepassfile = (PASSWORD FILE)
sslcacertfile = OS-DEFAULT
If you want to set up multiple IMAP accounts, just put them all in the ~/mail
folder and set ~/mail
as your database path for notmuch.
Here is a sample ~/.config/msmtp/config
, setting up a single SMTP server (also named "Work") with TLS:
defaults
auth on
tls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
logfile ~/.msmtp.log
account Work
host (SMTP SERVER)
port 587
from (EMAIL ADRESS)
user (USER NAME)
passwordeval cat (PASSWORD FILE)
account default : Work
You may need to change the 4th line if your system stores CA certificates in a different location.
Once offlineimap is set up, just run notmuch
from the command line to do some initial setup, which gets saved in ~/.notmuch-config
by default. You can set ~/mail
as your database path. notmuch has lots of options, the ability to set up various hooks and filters, and to sync certain IMAP markers with notmuch tags.
Here's a ~/.notmuch-config
which is roughly like the one I use:
[database]
path=/home/user/mail
[user]
name=First Last
[email protected]
[new]
tags=new
ignore=
[search]
exclude_tags=deleted;killed;spam;
[maildir]
synchronize_flags=true
