Advanced Build Options

By default nchat requires ~3.5GB RAM to build using G++ and ~1.5GB RAM with clang++, but it is possible to reduce the memory needed, see Building on Low Memory Systems.

All nchat features are enabled by default, but it's possible to control inclusion of some features using cmake flags, see Feature Flags.

Getting Started

In order to configure / setup an account one needs to run nchat in setup mode:

nchat --setup

The setup mode prompts for phone number, which shall be entered with country code. Example:

$ nchat --setup
Protocols:
0. Dummy
1. Telegram
2. WhatsAppMd
3. Exit setup
Select protocol (3): 1
Enter phone number (ex. +6511111111): +6511111111
Enter authentication code: xxxxx
Succesfully set up profile Telegram_+6511111111

If unsure of what phone number to enter, open the Telegram app on the phone and press the menu button and use the number displayed there (omitting spaces, so for the below screenshot the number to enter is +6511111111).

screenshot telegram phone

Once the setup process is completed, the main UI of nchat will be loaded.

In order to set up multiple protocols/profiles, exit nchat and perform the setup step again.

Troubleshooting

Refer to Debugging for details.

Telegram Group

A Telegram group https://t.me/nchatusers is available for users to discuss nchat usage and related topics.

Security

User data is stored locally in ~/.config/nchat. Default file permissions only allow user access, but anyone who can gain access to a user's private files can also access the user's personal Telegram data. To protect against the most simple attack vectors it may be suitable to use disk encryption and to ensure ~/.config/nchat is not backed up unencrypted.

Configuration

The following configuration files (listed with current default values) can be used to configure nchat.

~/.config/nchat/app.conf

This configuration file holds general application settings. Default content:

attachment_prefetch=1
attachment_send_type=1
cache_enabled=1
coredump_enabled=0
downloads_dir=
emoji_list_all=0
link_send_preview=1
logdump_enabled=0
proxy_host=
proxy_pass=
proxy_port=
proxy_user=
timestamp_iso=0

attachment_send_type

Specifies whether to detect file type (audio, video, image, document) and send attachments as those types, instead of sending all attachments as document type (which typically leaves original file content intact).

attachment_prefetch

Specifies level of attachment prefetching:

0 = no prefetch (download upon open/save)
1 = selected (download upon message selection) <- default
2 = all (download when message is received)

cache_enabled

Specifies whether to enable cache functionality.

coredump_enabled

Specifies whether to enable core dumps on application crash.

downloads_dir

Specifies a custom downloads directory path to save attachments to. If not specified, the default dir is ~/Downloads if exists, otherwise ~.

emoji_list_all

Specifies whether the emoji dialog should list all emojis, it is otherwise restricted to listing emojis that renders properly in common terminals.

link_send_preview

Specifies whether to enable preview for links in messages sent (Telegram only).

logdump_enabled

Specifies whether to dump warning and error log messages to stdout upon exit.

proxy_

SOCKS5 proxy server details. To enable proxy usage the parameters host and port are required, while user and pass are optional (depending on the SOCKS server). Note: In order to use a proxy while setting up nchat the first time, it is recommended to first run nchat without arguments (nchat) for its config dir to be created, and then edit proxy settings in ~/.config/nchat/app.conf as needed, before running nchat -s to setup an account.

timestamp_iso

Specifies whether to use ISO-style timestamps (YYYY-MM-DD HH:MM) in the UI and at export of chat history. By default nchat uses a dynamic "human-friendly" format:

  • HH:MM for timestamps on same date as today, e.g. 19:00
  • DAY HH:MM for timestamps in the last week, e.g. Mon 19:00
  • DD MMM HH:MM for timestamps in the current year, e.g. 14 Nov 19:00
  • DD MMM YYYY HH:MM for timestamps in non-current year, e.g. 14 Nov 2022 19:00
  • DD MMM YYYY HH:MM for timestamps during export, e.g. 14 Nov 2022 19:00

General

Deleting a configuration entry line (while nchat is not running) and starting nchat will populate the configuration file with the default entry.

Protocol-Specific Configuration

The following configuration files (listed with current default values) can be used to configure nchat.

~/.config/nchat/profiles/Telegram_+nnnnn/telegram.conf

This configuration file holds protocol-specific settings for Telegram. Default content:

local_key=
markdown_enabled=1
markdown_version=1
profile_display_name=

local_key

For internal use by nchat only.

markdown_enabled

Specifies whether to enable Markdown <-> text conversion for text messages (default enabled).

markdown_version

Specifies which Telegram Markdown version to use (default 1).

profile_display_name

Specifies an optional short/display name in the status bar when using nchat with multiple profiles. The default profile name is Telegram or Telegram_+nnnnn (when more than one Telegram profile is set up) if this setting is not specified.

~/.config/nchat/profiles/WhatsAppMd_+nnnnn/whatsappmd.conf

This configuration file holds protocol-specific settings for WhatsApp. Default content:

profile_display_name=

profile_display_name

Specifies an optional short/display name in the status bar when using nchat with multiple profiles. The default profile name is WhatsAppMd or WhatsAppMd_+nnnnn (when more than one WhatsAppMd profile is set up) if this setting is not specified.

FAQ

1. Alt/Opt-keyboard shortcuts are not working?

For Linux please ensure the terminal is configured with meta to send escape. For macOS Terminal ensure that the Terminal profile keyboard setting "Use Option as Meta key" is enabled.

If issues are still encountered, please use nchat -k (keydump mode) to determine the key codes and modify ~/.config/nchat/key.conf accordingly.

2. Send messages with Enter key?

To simply send on enter key press and skip message compose with linebreaks, one can just set send_msg=KEY_RETURN in ~/.config/nchat/key.conf.

To also be able to compose messages with linebreaks using Alt/Opt-Enter, edit ~/.config/nchat/ui.conf and set linefeed_on_enter=0. And in ~/.config/nchat/key.conf set linebreak=\33\15.

3. Custom colors are not shown when running nchat in tmux?

Please try to run nchat with a TERM supporting custom colors, e.g:

TERM=xterm-256color nchat

4. Sent messages are not visible?

For terminals with eight colors (or more) the default color theme displays sent messages in gray (shaded). Some terminals may wrongly report supporting more colors than two, or the terminal may be set up with gray mapped to black. In this case sent / own messages may appear invisible. To avoid nchat using gray one can edit ~/.config/nchat/color.conf and remove occurances of gray.

5. How to use Telegram and WhatsApp concurrently or switch between them?

The recommended method is to set up nchat with one config directory per protocol/phone number, and run each instance in separate terminal windows/tabs. To simplify such usage one can set up aliases, for example:

alias telegram='nchat -d ~/.config/nchat-telegram'
alias whatsapp='nchat -d ~/.config/nchat-whatsapp'

Then use regular setup for them (separately), for example:

telegram -s
whatsapp -s

The alternative method is to set up multiple protocol accounts in a single nchat config directory. For each protocol/phone nubmer, run setup mode and exit after initial sync:

nchat -s

Technical Details

Custom API Id / Hash

nchat uses its own Telegram API id and hash by default. To use custom id/hash, obtained from https://my.telegram.org/ one may set environment variables TG_APIID and TG_APIHASH when setting up a new Telegram account. Example (below values must be changed to valid api id/hash):

TG_APIID="123456" TG_APIHASH="aaeaeab342aaa23423" nchat -s

Third-party Libraries

nchat is primarily implemented in C++ with some parts in Go. Its source tree includes the source code of the following third-party libraries:

The tdlib and whatsmeow libraries are actively developed and need to be updated and integrated into nchat on a regular basis by nchat maintainer(s). To facilitate this there are scripts available to update to latest (or a specific) version of these libraries. Example usages:

./utils/tdlib-update 8517026

./utils/whatsmeow-update 7aedaa1

Code Formatting

Uncrustify is used to maintain consistent source code formatting, example:

./make.sh src

There is currently no concrete roadmap for further feature development of nchat. It is not intended to be a full-featured client on par with official Telegram / WhatsApp clients, but rather a light-weight client providing essential functionality suitable for the terminal. However, feel free to submit feature requests if there's something missing, or help upvote existing feature requests, and if it's useful and low effort it can probably be added.
