Wechat for Linux tips and tricks

The tweaks in this snippit applies to Wechat for Linux.

Theming

Apply light/dark theme (based on KDE color scheme).

WeChat stores general configuration files under ~/.local/share/xwechat_files/all_users/config/, at global_config. However, the file is encrypted, along with checksum global_config.crc.

One way around this is to save two copies of global_config and global_config.crc of light and dark theme. This can be done by adjusting the appearance setting in WeChat, exiting and backing-up the two files.

Disabling bloats

Most Wechat bloats are stored under /opt/wechat. The files/directories sorted by size are as follows (as of version 4.1.1)

$ du -ah --max-depth=1 /opt/wechat/ 2>/dev/null | sort -hr
717M    /opt/wechat/

RadiumWMPF is by far the largest, which refers to the WeChat Mini Program Framework; wechat is the main binary file; XFile provides previews to sent/received files.

Removing RadiumWMPF disables mini programs, including the "internet search" function.

Removing XFile will result in sent/received files being opened by default applications.

The two directories take up more than half the size of /opt/wechat.
