* README

=mastodon.el= is an Emacs client for the AcitivityPub social networks that
implement the Mastodon API. For info see https://joinmastodon.org/.

** Installation

Clone this repository and add the lisp directory to your load path.
Then, require it and go.

#+BEGIN_SRC emacs-lisp
    (add-to-list 'load-path "/path/to/mastodon.el/lisp")
    (require 'mastodon)
#+END_SRC

Or, with =use-package=:

#+BEGIN_SRC emacs-lisp
  (use-package mastodon
    :ensure t)
#+END_SRC

The minimum Emacs version is now 27.1. But if you are running an older version
it shouldn't be very hard to get it working.

*** MELPA

Add =MELPA= to your archives:

#+BEGIN_SRC emacs-lisp
  (require 'package)
  (add-to-list 'package-archives
               '("melpa" . "http://melpa.org/packages/") t)
#+END_SRC

Update and install:

=M-x package-refresh-contents RET=

=M-x package-install RET mastodon RET=

*** Emoji

=mastodon-mode= will enable [[https://github.com/iqbalansari/emacs-emojify][Emojify]] if it is loaded in your Emacs environment, so
there's no need to write your own hook anymore. =emojify-mode= is not required.

*** Discover

=mastodon-mode= can provide a context menu for its keybindings if [[https://github.com/mickeynp/discover.el][Discover]] is
installed. It is not required.

if you have Discover, add the following to your Emacs init configuration:

#+BEGIN_SRC emacs-lisp
  (require 'mastodon-discover)
  (with-eval-after-load 'mastodon (mastodon-discover))
#+END_SRC

Or, with =use-package=:

#+BEGIN_SRC emacs-lisp
  (use-package mastodon
    :ensure t
    :config
    (mastodon-discover))
#+END_SRC

** Usage

*** Logging in to your instance

You need to set 2 variables in your init file to get started:

1. =mastodon-instance-url=
2. =mastodon-active-user=

(see their doc strings for details). For example If you want to post
toots as "example_user@social.instance.org", then put this in your init
file:

#+BEGIN_SRC emacs-lisp
    (setq mastodon-instance-url "https://social.instance.org"
          mastodon-active-user "example_user")
#+END_SRC

Then *restart* Emacs and run =M-x mastodon=. Make sure you are connected
to internet before you do this. If you have multiple mastodon accounts
you can activate one at a time by changing those two variables and
restarting Emacs.

If you were using mastodon.el before 2FA was implemented and the above steps
do not work, delete the old file specified by =mastodon-client--token-file= and
restart Emacs and follow the steps again.

*** Timelines

=M-x mastodon=

Opens a =*mastodon-home*= buffer in the major mode and displays toots. If your
credentials are not yet saved, you will be prompted for email and password.
The app registration process will take place if your =mastodon-token-file= does
not contain =:client_id= and =:client_secret=.

**** Toot byline legend

|---------------+------------------------|
| Marker        | Meaning                |
|---------------+------------------------|
| =(B)=           | I boosted this toot    |
| =(F)=           | I favourited this toot |
| =(🔖)= (or (=K=)) | I bookmarked this toot |
|---------------+------------------------|

*** Composing toots

=M-x mastodon-toot= (or =t= from a mastodon.el buffer).

Pops a new buffer/window in =text-mode= and =mastodon-toot= minor mode. Enter the
contents of your toot here. =C-c C-c= sends the toot. =C-c C-k= cancels.
Both actions kill the buffer and window.

Autocompletion of mentions and tags is provided by =completion-at-point-functions= (capf) backends. =mastodon-toot--enable-completion= is enabled by default. If you want to enable =company-mode= in the toot compose buffer, set =mastodon-toot--use-company-for-completion= to =t=. (=mastodon.el= used to run its own native company backends, but these have been removed in favour of capfs.)

Replies preserve visibility status/content warnings, and include boosters by default.

Server's max toot length, and attachment previews, are shown.

You can download and use your instance's custom emoji
(=mastodon-toot--download-custom-emoji=, =mastodon-toot--enable-custom-emoji=).

The compose buffer uses =text-mode= so any configuration you have for that mode
will be enabled. If any of your existing config conflicts with =mastodon-toot=,
you can disable it in the =mastodon-toot-mode-hook=. For example, the default
value of that hook is as follows:

#+begin_src emacs-lisp
(add-hook 'mastodon-toot-mode-hook
          (lambda ()
              (auto-fill-mode -1)))
#+end_src

   - Timestamp format
   - Relative timestamps
   - Display user avatars
   - Avatar image height
   - Enable image caching
   - Hide replies in timelines

*** Alternative timeline layout

The incomparable Nicholas Rougier has written an alternative timeline layout for =mastodon.el=.

The repo is at https://github.com/rougier/mastodon-alt.

*** Live-updating timelines: =mastodon-async-mode=

(code taken from https://github.com/alexjgriffith/mastodon-future.el.)

Works for federated, local, and home timelines and for notifications. It's a
little touchy, one thing to avoid is trying to load a timeline more than once
at a time. It can go off the rails a bit, but it's still pretty cool. The
current maintainer of =mastodon.el= is unable to debug or improve this feature.

To enable, it, add =(require 'mastodon-async)= to your =init.el=. Then you can
view a timeline with one of the commands that begin with
=mastodon-async--stream-=.

*** Translating toots

You can translate toots with =mastodon-toot--translate-toot-text= (=a= in a timeline). At the moment
this requires [[https://codeberg.org/martianh/lingva.el][lingva.el]], a little interface I wrote to https://lingva.ml, to
be installed to work.

You could easily modify the simple function to use your Emacs translator of
choice (=libretrans.el= , =google-translate=, =babel=, =go-translate=, etc.), you just
need to fetch the toot's content with =(mastodon-tl--content toot)= and pass it
to your translator function as its text argument. Here's what
=mastodon-toot--translate-toot-text= looks like:

#+begin_src emacs-lisp
  (defun mastodon-toot--translate-toot-text ()
    "Translate text of toot at point.
    Uses `lingva.el'."
      (interactive)
      (let* ((toot (mastodon-tl--property 'toot-json)))
        (if toot
            (lingva-translate nil (mastodon-tl--content toot))
          (message "No toot to translate?"))))
#+end_src

*** bookmarks and =mastodon.el=
=mastodon.el= doesn’t currently implement its own bookmark record and handler, which means that emacs bookmarks will not work as is. Until we implement them, you can get bookmarks going immediately by using [[https://github.com/emacsmirror/emacswiki.org/blob/master/bookmark%2b.el][bookmark+.el]].

** Dependencies

Hard dependencies (should all install with =mastodon.el=):
- =request= (for uploading attachments), https://github.com/tkf/emacs-request
- =persist= for storing some settings across sessions
- =ts= for poll relative expiry times

Optional dependencies:
- =emojify= for inserting and viewing emojis
- =mpv= and =mpv.el= for viewing videos and gifs
- =lingva.el= for translating toots

** Network compatibility

=mastodon.el= should work with ActivityPub servers that implement the Mastodon API.

Apart from Mastodon itself, it is currently known to work with Pleroma and
Gotosocial. If you attempt to use =mastodon.el= with another server that
implements the Mastodon API and run into problems, feel free to open an issue.

** Contributing

PRs, issues, feature requests, and general feedback are very welcome!

1. =mastodon.el= has bugs, as well as lots of room for improvement.
2. I receive very little feedback, so if I don't run into the bug it often doesn't get fixed.
3. If you run into something that seems broken, first try running =mastodon.el=
   in emacs with no init file (i.e. =emacs -q= (instructions and code for doing
   this are [[https://codeberg.org/martianh/mastodon.el/issues/300][here]]) to see if it also happens independently of your own config
   (it probably does).
4. Enable debug on error (=toggle-debug-on-error=), make the bug happen again,
   and copy the backtrace that appears.
5. Open an issue here and explain what is going on. Provide your emacs version and what kind of server your account is on.

*** Fixes and features

1. Create an [[https://codeberg.org/martianh/mastodon.el/issues][issue]] detailing what you'd like to do.
2. Fork the repository and create a branch off of =develop=.
3. Run the tests and ensure that your code doesn't break any of them.
4. Create a pull request referencing the issue created in step 1.

*** Coding style

- This library uses an unconvential double dash (=--=) between file namespaces and function names, which contradicts normal Elisp style. This needs to be respected until the whole library is changed.
- Use =aggressive-indent-mode= or similar to keep your code indented.
- Single spaces end sentences in docstrings.
- There's no need for a blank line after the first docstring line (one is added automatically when documentation is displayed).

** Supporting =mastodon.el=

If you'd like to support continued development of =mastodon.el=, I accept

prefer a different payment method, write to me at that address and I can
provide IBAN or other details.

I don't have a tech worker's income, so even a small tip would help out.
