// ConsoleHandler formats slog.Logger output in console format, a bit similar with Uber's zap ConsoleEncoder
// The log format is designed to be human-readable. 
// 
// Performance can definitely be improved, however it's not in my priority as 
// this should only be used in development environment.

// e.g. log output:

不同分词器在elastic中的实际效果

介绍不同分词器的文章不少，较经典的有BosonNLP 11款开放中文分词引擎大比拼

可惜这11款分词器只有IK和结巴一直在更新elastic的分词器插件，Boson的插件已经很久没更新

所以加上elastic自带的smartcn 也就只有三种分词器可选。

注1：smartcn基于中科院的ictclas 但用的是1.0， 似乎没再更新

--[[

Prevent the screen from blanking while a video is playing.

This script is a workaround for the GNOME+Wayland issue documented in the
[Disabling Screensaver] section of the mpv manual, and depends on
gnome-session-inhibit (usually provided by the gnome-session package) to set up
the inhibitors.
