== 基础知识 ==

== 配置文件 ==
=== 概览 ===
conky 1.10开始，配置文件使用[[lua]]语法，conky 1.7.1 开始内置了lua。配置文件主要由两部分组成，如下：
<syntaxhighlight lang="lua">
-- 显示的配置
conky.config = {

}

-- 显示的内容
conky.text = [[

]]
</syntaxhighlight>

hello world版配置文件：
<syntaxhighlight lang="lua">
-- 显示的配置
conky.config = {
    update_interval=10,       -- 刷新时间，10秒
    alignment = 'top_left',   -- 左上角显示
    own_window = true,        -- 界面显示
    own_window_hints = 'undecorated,below,sticky,skip_taskbar,skip_pager',
}

-- 显示的信息
conky.text = [[
hello world !

cpu: ${cpu}%
users：${user_number}
]]
</syntaxhighlight>

将配置保存到一个文件，如conkyrc，指定配置文件启动：<code>conky -c conkyrc</code> 。

=== 配置文件位置 ===
使用<code>conky -v</code>可以看到版本默认配置文件位置等信息。
* 系统配置文件位置：<code>/etc/conky/conky.conf</code>
* 用户配置文件位置：<code>$HOME/.conkyrc</code>
当运行<code>conky</code>时，程序先加载当前用户的配置文件，如果不存在再加载系统配置文件。当然也可以再运行时指定配置文件：<code>conky -c myconkyrc</code>。用户配置文件刚安装时不存在，可以复制系统配置文件到用户配置文件位置 <code>cp /etc/conky/conky.conf $HOME/.conkyrc</code>，再进行修改。
以下为默认配置文件内容：
<syntaxhighlight lang="lua">
-- vim: ts=4 sw=4 noet ai cindent syntax=lua
--[[

== 常见问题 ==
* 中文显示乱码。需要设置支持中文的字体。
<br \>1.查看系统中的中文字体：<code>fc-list :lang=zh</code> ，选择一个字体如<code>Noto Serif CJK SC</code>。
<br \>2.conky配置文件中<code>conky.config = {}</code>中设置： <code>font = 'Noto Serif CJK SC:size=12',</code>
