Beautiful Desktop Calendar rainlendar

The "transaction plan" Diary "" and "Reminder" in Linux have never been implemented by any good software. There may be, but I don't know or can't find it, I like small, concise, and powerful software. The current temporary method is:
Transaction plan: shell scripts implement a todo function;
Diary: Vim diary;
The "Reminder" function is a better tool.
Today, I occasionally found that rainlendar also has a Linux version. That's great. I used to pick it out in windows. It's small, powerful, green, and free of charge. It has been used for several years, it's too good for me. I just don't know whether it is cross-platform or a Linux version. We recommend that you use it. View its implementation and implement it using Lua.

Rainlendar is a pretty desktop calendar tool with event reminder

Download and unzip the package
$ Tar jxvf Rainlendar-Lite.tar.bz2
You can run
$./Rainlendar2

The default English interface supports Chinese characters. If you want to use it, download the Simplified Chinese package simplified_chinese.r2lang:
Method: run in the terminal
$./Rainlendar2-I/path to the Language Pack you downloaded/simplified_chinese.r2lang

Finally, run rainlendar2 again, right-click the interface, options...
Select Chinese (simplified)/OK in/language,
The Chinese interface appears.

Now, the conversion from windows to Linux is getting smaller and smaller. Because I used to use things in windows, I still use them in Linux. For example:
Browser: Opera, even my profile configuration is the same, custom shortcut keys and so on, no difference, and opera
Linux updates are not slow at all;
Editing tool: Vim. The configuration is also available on the platform;
Scheduled reminder: rainlendar
Audio/Video Playback: mplayer

For platform change, the inconsistencies are as follows:
Email: in windows, I used Becky, which is small and powerful. Unfortunately, I didn't have a Linux version. I tried several of them, but I don't like it. Now I use opera.
Mail, OK;
File Manager: Use totalcmd in windows and unmatched tools in Linux
Download tool: No one is comparable to thunder;
