Telega Manual

• GNU Emacs (at least 26.1 is required with svg support)
• GNU make (known as gmake on BSD platforms)
• GNU gperf (for building TDLib)
• CMake (for building TDLib)
• pkg-config (for building telega-server)

Optional dependencies:

• Python (optional, for testing the telega-server)
• GNU Guix (optional, if using the Guix installation method)
• libappindicator3 (optional, to show telega icon/info in system tray)
• dwebp (optional, to display Stickers)
• tgs2png (optional, for Animated Stickers), sources are at https://github.com/zevlg/tgs2png

make is found in most of the modern machines. The other packages can be download with the system package manager (such as apt for Debian-based distributions, dnf for Fedora or pacman for Arch-based).

1. If you are using Emacs For Mac OS X, or you installed Emacs by running $ brew cask install emacs, make sure you installed a recent enough version (>= emacs-27.1-mac-8.1, you can check your version by running $ brew info emacs-mac or $ brew cask info emacs-mac) with rsvg support ($ brew install emacs-mac --with-librsvg), or your Emacs may not display some media correctly, in this case consider switching to emacs-plus.

2. If you are using Emacs-mac, or you installed Emacs by running $ brew install emacs-mac or $ brew cask install emacs-mac, your Emacs has bug dealing with complex svg, which leads to Emacs hangups. Compiling Emacs with rsvg support by running $ brew install emacs-mac --with-librsvg will fix this problem.

   NOTE: telega cannot display stickers correctly with emacs-mac, even when emacs-mac is compiled with rsvg support. If you want sticker support, please consider switching to emacs-plus.

3. emacs-plus is the best choice to run telega.

telega requires at least GNU Emacs 26.1 with optional, but highly recommended, svg support. If Emacs version is less then 27.1, then imagemagick is also required. Most distributions provide GNU Emacs compiled with these dependencies when installing GNU Emacs with GTK+ support (graphical).

See detailed description how to install telega under Windows 10.

TDLib is the library for building Telegram clients. It requires a large amount of memory to be built. Make sure you are using TDLib version equal to v1.8.45-521aed8e4.

On MacOS you can install a pre-built TDLib package using homebrew from brew.sh. Just run:

$ brew install tdlib --HEAD

On Linux, you will need to build TDLib from source. Use TDLib build instructions generator for comprehensive build instructions.

In general, you need to install all TDLib dependencies then get TDLib sources and compile them using CMake.

To get the source:

$ git clone https://github.com/tdlib/td.git

Move into the folder with $ cd ./td or wherever you checked out td.

Prepare a folder for building the library:

$ mkdir build && cd build && cmake ../

Build the sources:

$ make -jN

with N number of cores that should be used for the compilation (the optimal value is the number of physical cores on the machine).

Finally, to install the library system-wide:

$ sudo make install

It will install headers to /usr/local/include and library itself into /usr/local/lib. If you have TDLib installed in other location, don't forget to modify telega-server-libs-prefix before starting telega.

For Linux users, make sure /usr/local/lib is in your ldconfig cache, otherwise telega server build will fail.

If you use telega from master and update it from time to time it might ask you to update/rebuild TDLib and telega-server. To update TDLib and rebuild telega-server do next:

1. Fetch, rebuild and reinstall updated TDLib as described above
2. On Linux run $ sudo ldconfig to refresh ldconfig cache
3. Run $ make server-reinstall in the telega.el sources directory to rebuild and reinstall telega-server

Now you are ready to run updated telega.

telega and TDLib are both available in GNU Guix. If you have a resource constrained machine or would simply prefer to bypass compiling TDLib from source, this is a good option!

On Guix System:

$ guix package -i emacs-telega font-gnu-{unifont,freefont}

The latter two packages provide glyphs used by telega.

On "Foreign" Distributions:

• Use the shell installer script, or install GNU Guix manually on-top of your current distribution. Installation Documentation
• Enable fetching substitutes from the build server cache if you do not wish to build from source. Substitute Server Authorization

• And finally, run:

  $ guix package -i emacs emacs-telega
  

It is easiest to use the version of Emacs installed from GNU Guix because it is modified with an autoloader to identify and automatically use Emacs packages installed from Guix. Alternatively, if you wish to use the bundle of Emacs provided by your distribution, you may install the telega elisp sources through MELPA and use Guix to provide the server binary precompiled.

Consult the official GNU Guix documentation for further questions. Issues related to the GUIX package must be accompanied by the GUIX label in the issue tracker.

Do note that since telega is actively maintained installations from Guix might at times lag behind master, but regular attempts to keep it updated will occur. If the version in Guix is too outdated or is missing a feature, please use the protocol for the issue tracker.

telega is available from MELPA, so you can install it from there as usual package. This is a preferable method, because it will automatically handle all dependencies and provides autoloads.

For TDLib 1.8.0 release you might consider stable telega version. Stable telega version won't require you to rebuild TDLib until next TDLib 1.9.0 release, telega updates will work with 1.8.0. Stable telega is placed in MELPA Stable. Package configuration for telega from MELPA Stable might look like:

(add-to-list 'package-archives
             '("melpa-stable" . "https://stable.melpa.org/packages/"))
(add-to-list 'package-pinned-packages '(telega . "melpa-stable"))

telega from unstable MELPA is a bleeding edge of the telega development and telega updates might require also TDLib update/rebuild sometimes. However, it brings you all newer (probably incompatible with TDLib 1.8.0) functionality faster, no need to wait for TDLib 1.9.0 to access newer features.

Or you could use git repository with this melpa-style recipe for quelpa:

(quelpa '(telega :fetcher github
                 :repo "zevlg/telega.el"
                 :branch "master"
                 :files (:defaults "contrib" "etc" "server" "Makefile")))

Make sure dependencies are installed with M-x package-install RET visual-fill-column RET and M-x package-install RET rainbow-identifiers RET.

Get the source:

$ git clone https://github.com/zevlg/telega.el
$ cd telega.el
$ make compile

Finally load telega into Emacs using:

(use-package telega
  :load-path  "~/telega.el"
  :commands (telega)
  :defer t)

Or with:

(add-to-list 'load-path "~/telega.el")
(require 'telega)

The code should be put in the configuration file for Emacs, which usually is init.el, or emacs.el.

Pull latest telega-server image:

$ docker pull zevlg/telega-server:latest

Make telega know you want to use docker by adding this to your init.el:

(setq telega-use-docker t)

That's it, you are ready to get starting. However, you might anyway need to have local ffmpeg installation to utilize some telega features, such as playing audio/voice messages, capturing video/voice notes, etc.

Type a text in the chatbuf input and press RET to send the message. To insert newline in the middle of the input use ordinary C-j Emacs command. To preview resulting message before sending it, press M-RET (telega-chatbuf-input-preview).

You can apply markup to the input when sending message. This is controlled by number of C-u pressed before RET and value of the:

• User Option: telega-chat-input-markups

  Markups to apply when sending input with RET. Each index in the list corresponds to the number of C-u supplied before RET, i.e. first element is used for ordinary RET, second is used for C-u RET, and third is for C-u C-u RET and so on. Supported markups are defined in the telega-chat-markup-functions.

  "markdown1" syntax is not recommended, it always treats underscore as starting point of italic emphasize even inside URLs, thats why "markdown1" is not included into telega-chat-input-markups by default.

  Default value: (nil "markdown2" "org")

Markup syntax table:

There is also "markdown1" syntax to insert multiline code blocks of specified languge:

```<language-name>
first line of multiline preformatted code
second line
last line```

"markdown2" backquotes syntax to insert multiline code blocks is controlled by:

• User Option: telega-markdown2-backquotes-as-precode

  Non-nil for markdown1 style syntax for ```. Non-nil activates syntax: ```<language-name> (not displayed) code code ```

  Default value: known

Org syntax for code blocks is NOT YET supported:

#+begin_src <language-name>

To reply to a message, put point on the message you want to reply to and press r, <down-mouse-3> <reply> (telega-msg-reply).

Selected region at reply time will be a reply quote.

To cancel reply use C-c C-k, C-M-c, M-ESC (telega-chatbuf-cancel-dwim) binding. C-u prefix to this command will clear chatbuf's input along with canceling reply.

To edit a given message, put point on the message you want to edit and press e, <down-mouse-3> <edit> (telega-msg-edit).

To cancel editing use the same command as for canceling reply to a message.

To edit your previously sent message press M-p (telega-chatbuf-edit-prev).

It is possible to edit a message using markup syntax. e, <down-mouse-3> <edit> (telega-msg-edit) accepts C-u prefix to specify markup syntax to be used for editing.

To forward a message, put cursor under the message which you want to forward and press f, <down-mouse-3> <forward> (telega-msg-forward-dwim) and then select a Chat to forward a message to. To forward multiple messages at once, mark messages with the m, <down-mouse-3> <mark> (telega-msg-mark-toggle) and then press f, <down-mouse-3> <forward> (telega-msg-forward-dwim) on one of the messages.

There are few options how you can affect the way a message is forwarded:

1. C-u f to forward a message copy, it will look like you sent a message.
2. C-u C-u f To forward a message copy deleting or replacing caption it has. Use this to forward media message with your own caption.

To delete a message, put cursor under the message you want to delete and press (telega-msg-delete-marked-or-at-point).

As with forwarding messages, you can mark multiple messages to delete with m, <down-mouse-3> <mark> (telega-msg-mark-toggle).

Also, you can ban/report message sender (and delete all messages from this sender in the chat) with B, <down-mouse-3> <ban-sender> (telega-msg-ban-sender) when cursor is under the message.

telega can keep deleted messages visible until chatbuf is killed. This is controlled using custom variable:

• User Option: telega-chat-show-deleted-messages-for

  Chat Temex for chats where to show deleted messages in chatbuf.

  Default value: nil

For example, to show deleted messages in all chats except for "Saved Messages", use next:

(setq telega-chat-show-deleted-messages-for '(not saved-messages))

To schedule a message, press C-c C-a scheduled RET, select date and time to schedule message at, type text of a message and send it as always.

To reschedule a message, first list all scheduled messages in the chat with C-c / scheduled RET, then press e, <down-mouse-3> <edit> (telega-msg-edit) on the message you want to reschedule, remove previous "Schedule" attachment and add a new one at the beginning.

Message scheduled in "Saved Messages" chat is called reminder.

Whenever a scheduled message or reminder is sent, you get a special notification marked with a 📅, so you don't get caught off-guard by messages you planned in the past.

You can navigate your previous chatbuf input using commands:

M-p (telega-chatbuf-edit-prev)

Edit previously sent message. MARKUP-ARG could be used to select markup to edit message. See telega-msg-edit for details.

M-n (telega-chatbuf-edit-next)

Edit message sent next to currently editing. MARKUP-ARG could be used to select markup to edit message. See telega-msg-edit for details.

M-r (telega-chatbuf-input-search)

Search for REGEX in chat input history.

While searching input, you can use M-p (telega-chatbuf--input-search-input-prev) and M-n (telega-chatbuf--input-search-input-next) to cycle chatbuf input ring.

Powerful company-mode can be used to complete input in the chatbuf with TAB (telega-chatbuf-complete-or-next-link).

telega provides few company backends, such as:

telega-company-emoji

Complete emojis via :<emoji>: syntax. Completion is done using predefined set of emojis.

Customizable Options:

• User Option: telega-company-emoji-fuzzy-match

  Non-nil to use fuzzy prefix matching. For example without fuzzy matches, prefix :jo will match only :joy:, :joy-cat: and :joystick:. With fuzzy matching enabled it will match also :flag-jo: and :black-jocker:.

  Default value: t

telega-company-telegram-emoji

Same as telega-company-emoji, but uses Telegram cloud for the emojis completion.

telega-company-username

Complete user mentions via @<username> syntax. Here is the screenshot, showing use of this backend:

Use @@ prefix to complete chat admins only.

Customizable options:

• User Option: telega-company-username-prefer-name

  Preferred formatting argument to the telega-user-title to complete user. First giving non-nil result will be used.

  Default value: (username first-name last-name)

• User Option: telega-company-username-show-avatars

  Non-nil to show avatars in the company annotation.

  Default value: nil

• User Option: telega-company-username-markup

  Markup to use for usernames completion.

  Default value: nil

telega-company-hashtag

Complete common hashtags via #<hashtag> syntax.

telega-company-botcmd

Complete bot commands via /<botcmd> syntax. This backend does not complete if /<botcmd> syntax is used in the middle of the chatbuf input, only if /<botcmd> starts chatbuf input.

telega-company-markdown-precode

Complete language name for code blocks via ``` syntax.

List of company backends to be used for user input completion is controlled by:

• User Option: telega-company-backends

  Company backends to use in chat buffers. Set to nil to disable company completions in chat buffers.

  Default value:

  (telega-company-emoji telega-company-telegram-emoji
                        telega-company-username telega-company-hashtag
                        telega-company-markdown-precode
                        telega-company-botcmd)
  

You can use completion without enabling company-mode in the chat buffers, by explicitly pressing TAB (telega-chatbuf-complete-or-next-link) to perform completion at point.

On the other hand, company-mode detects input context and pops up completion candidates if completion at point is available. To enable company-mode in chat buffers use:

(add-hook 'telega-chat-mode-hook 'company-mode)

Consider also using company-posframe Emacs package (in MELPA), so chatbuf's contents remain untouched when completion menu pops above the chatbuf prompt.

If you don't like company-posframe, consider option:

• User Option: telega-company-tooltip-always-below

  Non-nil to show company tooltip always below the point. Done by recentering point in the chatbuf.

  Default value: t

If chatbuf input starts with @<botname> <query> and mentioned bot support inline mode, then pressing TAB (telega-chatbuf-complete-or-next-link) will pop a special buffer with the inline results to the bot inline <query>, you can use these results to send a message via bot. Some useful bots with inline mode support are:

• @gif To search and send animations
• @pic, @bing To search and send pictures
• @vid To search and send videos on YouTube
• @foursquare - To find and send places around the world
• etc

To find out is some bot supports inline mode or not, enter @<botname><SPC> in chatbuf input and press TAB (telega-chatbuf-complete-or-next-link). If momentary help is displayed, then this bot supports inline mode.

Customizable options for inline bots:

• User Option: telega-known-inline-bots

  List of known bots for everyday use.

  Default value: ("@gif" "@youtube" "@pic")

• User Option: telega-inline-query-window-select

  Non-nil to select window with inline query results.

  Default value: t

Message filtering means to show only some messages matching filter. Available message filters are: scheduled, search, by-sender, hashtag, topic, tag, photo, photo-video, url, doc, file, gif, audio, video, voice-note, video-note, voice-video-note, chat-photo, mention, unread-mention, unread-reaction, failed-to-send, pinned

Chatbuf uses next bindings for message filtering:

C-c / (telega-chatbuf-filter)

Enable chat message filtering MSG-FILTER.

C-c C-c (telega-chatbuf-filter-cancel)

Cancel current messages filtering. If point is at some message, then keep point on this message after reseting. If C-u is given, then cancel thread filtering as well.

C-c C-r (telega-chatbuf-inplace-search-query)

Inplace search backward for the QUERY. If C-u is given, search for the messages containing QUERY sent by specified SENDER. To navigate across searching results use M-g p and M-g n bindings.

C-c C-s (telega-chatbuf-inplace-search-query-forward)

Inplace search forward for the QUERY. If C-u is given, search for the messages containing QUERY sent by specified sender.

Use C-c C-r (telega-chatbuf-inplace-search-query) or C-c C-s (telega-chatbuf-inplace-search-query-forward) to start searching while keeping history without applied filter, i.e. you can see surrounding messages.

Use M-g s (telega-chatbuf-inplace-search) or M-g n (telega-chatbuf-inplace-search-next) to continue searching.

Document messages in Telegram has attached file in the message. By default telega opens that files inside Emacs using find-file function. Sometimes that is not desirable behaviour and you might want to open some files in external application. You can use org-open-file function for this. Behaviour is controlled by:

• User Option: telega-open-file-function

  Function to use to open files associated with messages. Called with single argument - filename to open. Could be used to open files in external programs. Set it to org-open-file to use Org mode to open files.

  Default value: find-file

Setup to open some files in external applications might look like:

;; ("\\.pdf\\'" . default) is already member in `org-file-apps'
;; Use "xdg-open" to open files by default
(setcdr (assq t org-file-apps-gnu) 'browse-url-xdg-open)

(setq telega-open-file-function 'org-open-file)

On MacOS use browse-url-default-macosx-browser instead of browse-url-xdg-open.

If you also want to open non-document messages as file using telega-open-file-function consider:

• User Option: telega-open-message-as-file

  List of message types to open as file using telega-open-file-function. Supported message types are: photo, video, audio, video-note, voice-note, animation. Document messages are always opens as file.

  Default value: nil

Another alternative to open some files using external programs is to use nice openwith Emacs package available in MELPA.

Browse URL with custom function

Also, you can open urls using custom functions:

• User Option: telega-browse-url-alist

  Alist of custom url browse functions. Each element is in form: (PREDICATE-OR-REGEX . FUNCTION).

  Default value: nil

For example, to play youtube videos using mpv player, add this to config:

(defun my-watch-in-mpv (url)
  (async-shell-command (format "mpv -v %S" url)))

(add-to-list 'telega-browse-url-alist
             '("https?://\\(www\\.\\)?youtube.com/watch" . my-watch-in-mpv))
(add-to-list 'telega-browse-url-alist
             '("https?://youtu.be/" . my-watch-in-mpv))

In official telegram clients all messages in group chats are displayed even if message has been sent by blocked sender (user or chat). telega has client side message ignoring feature implemented. Ignoring messages can be done by adding function into telega-msg-ignore-predicates. This function must accept single argument - message, and return non-nil if messages should be ignored. You can use telega-match-gen-predicate to generate message predicates out of Telega Match Expressions. For example, to ignore messages from particular user with id=12345 you could add next code:

(defun my-telega-ignore-12345-user (msg)
  (telega-msg-match-p msg '(sender (ids 12345))))

(add-hook 'telega-msg-ignore-predicates 'my-telega-ignore-12345-user)

Or to ignore messages from blocked senders (users or chats), just add:

(add-hook 'telega-msg-ignore-predicates
          (telega-match-gen-predicate 'msg '(sender is-blocked)))

To view recently ignored messages use M-x telega-ignored-messages RET command.

Any message in any chat can be marked with as favorite. Favorite messages are labeled with:

• User Option: telega-symbol-favorite

  Symbol to use for favorite messages, bookmarks.

  Default value: "🔖"

To toggle message at point being favorite, press *, <down-mouse-3> <favorite> (telega-msg-favorite-toggle).

To jump to a favorite message before message at point in the chat buffer, press M-g * (telega-chatbuf-prev-favorite).

To view all favorite messages in all chats, enable "Favorite Messages" Root View, by pressing v * (telega-view-favorite-messages) in the root buffer.

Some media messages that are playing inside Emacs (such as "audio", "voice-note" or "video-note" messages) will have additional media control buttons to control media playback parameters:

[⏪] [⏩] [2×] [Stop] 

For fast access to media controls you can you next bindings:

0 (telega-msg--vvnote-stop)

Stop playing media message.

<, , (telega-msg--vvnote-rewind-10-backward)

Rewind 10 seconds backward.

>, . (telega-msg--vvnote-rewind-10-forward)

Rewind 10 seconds forward.

x (telega-msg--vvnote-play-speed-toggle)

Toggle playback speed for the media message. Only two modes are available: normal speed and x2 speed.

9, 8, 7, 6, 5, 4, 3, 2, 1 (telega-msg--vvnote-rewind-part)

Rewind to the N's 10 part of the message duration. I.e. if you press 7, then you will jump to 70% of the message duration.

To play/pause media messages use RET. Also, l, <down-mouse-3> <copy-link> (telega-msg-copy-link) command supports linking to the currently playing (or paused at) moment.

To reference a given moment in a media message (or in a reply to media message) use [HH:]MM:SS] syntax in the message's body/caption. Such timestamp marks will be automatically emphasised with a media timestamp text entity.

Telegram allows creating forums with multiple distinct topics. Use M-x telega-chat-create RET forum RET to create forums.

NOTE: forums and topics are not fully supported by telega at moment.

telega supports animated stickers using tgs2png utility from https://github.com/zevlg/tgs2png

Once tgs2png tool is installed into exec-path (check value for telega-sticker-animated-play after telega is started), you can play animated stickers by pressing RET on sticker.

Also telega-autoplay-mode can be used, to automatically animate messages containing animated stickers.

To attach your favorite or rencetly used sticker use C-u before C-c C-a sticker RET. Background for favorite stickers are filled with color:

• User Option: telega-sticker-favorite-background

  Background color for the favorite stickers. Can be nil, in this case favorite stickers are not outlined.

  Default value: "cornflower blue"

To toggle sticker being favorite, press *, f (telega-sticker-toggle-favorite) while point is under sticker in the *Telega Sticker Set* buffer.

Or you can press S, <down-mouse-3> <save> (telega-msg-save) on the sticker message to add that sticker to the favorite stickers list.

There are multiple methods you can use to attach an animation:

• C-c C-a animation RET to attach animation from the Saved Animations list.

To explicitly add animation to Saved Animations list, press S, <down-mouse-3> <save> (telega-msg-save) on the corresponding animation message.

telega.el can notify you about incoming messages and calls via D-Bus notifications, however notifications are disabled by default.

Enable it with (telega-notifications-mode 1) or at telega load time:

(add-hook 'telega-load-hook 'telega-notifications-mode)

Message is triggered for messages matching:

• User Option: telega-notifications-msg-temex

  Message temex to match messages that needs to be notified.

  Default value: (call telega-notifications-msg-notify-p)

You can use this option for custom notifications. For example to trigger notification for messages containing "keyword" (in addition to default behaviour) you can set telega-notifications-msg-temex to (or (call telega-notifications-msg-notify-p) (contains "keyword"))

By default notification triggers if telega-notifications-msg-notify-p predicate returns non-nil. It returns non-nil if next conditions are satisfied.

(setq telega-bridge-bot-bridge-info-plist
      '(-1001773572820 ; id of the @emacs_china

Q: I've got a lot of [telega bug] things in the rootbuf or chatbuf.

A: Set debug-on-error to non-nil and trigger the bug to get the backtrace buffer. Report this backtrace to github issues or to the telega.el Telegram Chat

Q: Stickers are not fully shown, I see only outlines for some stickers, like on the screenshot:

A: If your Emacs does not have bultin WEBP format support. telega will use dwebp tool to convert stickers from WEBP format to the format supported by your Emacs. See Stickers / Animations for details. So, make sure dwebp tool is available on your machine.

Q: I've enabled telega-notifications-mode as described in the manual, but notifications still does not pop up.

A: Make sure your time is correct. Eval (telega-time-seconds) to get UTC time in your Emacs, it should be more or less the same as on https://www.unixtimestamp.com/
