telegrust-histo

为什么？我很好奇，虽然 Python 在那里生成的图表看起来更好看，但它解析时间戳的速度太慢了。

安装

# install telegrust-histo with cargo, 
# provided that you have the rust toolchain set up.
cargo install telegrust-histo

用法

# cd to wherever your exported folder is
cd ~/Downloads/Telegram\ Desktop/ChatExport_2021-01-15 

# print options
telegrust-histo -help

# run it
telegrust-histo -b 300 -v

演示

~/ChatExport_2021-01-15> time telegrust-histo -b 200  # time is optional btw of course
