# [zh-cn]前言：你可以通过下面的方法一步一步在服务器配置EFB
# [en]Prefix: You can follow the commands to set up your EFB on your VPS.
# [zh-cn]注意：这不是一个自动化脚本，仅提供思路和步骤参考
# [en]Caution: This is not a sh file, only cover with my way to success.
# Ubuntu 16.04.3 LTS / 18.04 LTS with sudo

# [zh-cn]首先，升级你的软件包并安装所需的依赖
sudo apt update && sudo apt upgrade -y && 
sudo apt install wget curl screen vim ffmpeg libmagic-dev libwebp-dev libsqlite3-dev -y

# [zh-cn]下载Miniconda并安装
wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash ./Miniconda3-latest-Linux-x86_64.sh

# [en]Restart your terminal
# [en]If you are connect with ssh, you should first `exit` and then `ssh ip` again
conda create -n efb pip
source activate efb

# [zh-cn]这是python环境安装的替代方法，如果上面的miniconda无法正常安装，请参考这里
# curl -L https://raw.githubusercontent.com/pyenv/pyenv-installer/master/bin/pyenv-installer | bash
# export PATH="$HOME/.pyenv/bin:$PATH"
# eval "$(pyenv init -)"
# eval "$(pyenv virtualenv-init -)"
# pyenv install 3.6.4
# pyenv global 3.6.4

# [zh-cn]接着你需要在Telegram获取到你的bot api、bot管理员id
# [en]for TG bot token and admin id, you can refer to this url: https://www.ynewtime.com/EFB-sh
export TGBOTTOKEN=""
export TGADMIN=""

# [zh-cn]初始化python环境并安装ehforwarderbot
pip install ehforwarderbot efb-telegram-master efb-wechat-slave imageio_ffmpeg

# [zh-cn]创建并写入EFB的配置文件
mkdir -p ~/.ehforwarderbot/profiles/default/blueset.telegram

cat>~/.ehforwarderbot/profiles/default/config.yaml<<EOF
master_channel: "blueset.telegram"
slave_channels:
- "blueset.wechat"
EOF

cat>~/.ehforwarderbot/profiles/default/blueset.telegram/config.yaml<<EOF
token: "$TGBOTTOKEN"
admins:
- $TGADMIN
EOF

# [zh-cn]使用screen启动ehforwarderbot
# [zh-cn]注意：启动成功后退出screen环境要用快捷键ctrl+a -> ctrl+d
# [en]press ctrl+a and ctrl+d to go back to terminal
# [zh-cn]注意：ctrl+c会导致screen进程终止，请谨慎使用
screen ehforwarderbot

# 后续：
# 按照上面的步骤创建完的bot是没有显式的把命令标注在bot底端输入栏的，
# 因此，你需要去@BotFather那儿自定义一串命令，操作步骤是：
# /mybots - (选择你的bot) - Edit Bot - Bot Commands - 输入下面的文字：
# chat - 开启会话
# link - 将会话绑定到Telegram群组
# extra - 获取
# 搞定。

# 2018-10-18补充：如果要将某些特定的群组或会话绑定到Telegram的自定义群组，
# 请记得在 @BotFather 处将你的 bot 修改为 inline bot，根据上面类似的步骤即可。
