sway配置

对于 12.5 英寸、分辨率1366x768 的小屏 ThinkPad X220笔记本 ，每个像素的空间都弥足珍贵。既然我选择sway，就需要通过微调来实现极致的紧凑布局。

窗口标题栏

首先想到的是缩减窗口标题栏字体，默认的字体在小屏上过大导致窗口标题栏非常"厚重"，Google Gemini建议调整全局字体，使用较小的等宽字体:

配置 ~/.config/sway/config 调整全局字体

# 设置全局字体，建议使用像素字体或较小的等宽字体
font pango:monospace 8

# 设置标题栏文字边缘留白
titlebar_padding 1
# 标题栏边框
titlebar_border_thickness 0

说明:

• titlebar_padding <horizontal> [<vertical>] 设置文字左右两侧和上下两侧的像素间距，当设置为1时候极致压缩标题栏(变窄)，紧贴字体大小

• titlebar_border_thickness 0 是为了处理特定布局(Stacked堆叠模式或Tabbed标签模式)标签页的边框彻底去除

上述简单调整全局字体确实有效，能够将标题栏和状态栏都缩减宽度。但是有一个不足是由于全局生效，就不能分别调整状态栏和窗口标题栏字体。实际上我希望将窗口标题栏完全去除，但是保留状态栏信息显示(因为当前桌面编号，当前时间，当前系统负载等信息需要在状态栏观察)

隐藏标题栏

How can I remove the tittle bar? #6946 提供了一个将标题栏完全移除的方法:

移除标题栏

#https://github.com/swaywm/sway/issues/6946
default_border pixel 1
default_floating_border 1
font pango:monospace 0.001
titlebar_padding 1
titlebar_border_thickness 0

说明:

• 现在字体不再支持设置为 0 ，所以这里使用了一个非常小的数值 0.001

• 这里保留 border 一个像素宽度是为了能够在窗口聚焦激活时保留一个蓝色的边框，方便和其他没有聚焦的窗口区别。当然也可以设为0(如果都是 foot轻量级终端 终端平铺不太好区分边界)

• smart_borders on 表示如果只有一个窗口，则自动关闭边框

压缩间隙

为了压缩窗口之间的间隙，可以设置 gaps :

移除窗口之间的间隙

gaps inner 0
gaps outer 0
smart_gaps on

说明:

• smart_gaps on 表示如果只有一个窗体，自动关闭外间距(Gaps)

状态栏

在上述窗体配置完成后，其实主要是全局字体设置为 0.001 之后，会看到状态栏上 所有文字消失 。实际上是因为全局字体影响，导致状态栏字体也缩小到看不见了。

解决的方法是在配置文件中，对 bar 段落单独设置字体，并且可以设置为自动隐藏，仅在按下Mod键时候显示

配置 bar 独立字体并设置为自动隐藏

bar {
    font pango:monospace 8

    position top
    height 20

    mode hide
    hidden_state hide
    modifier Mod4

    # When the status_command prints a new line to stdout, swaybar updates.
    # The default just shows the current date and time.
    status_command while date +'%Y-%m-%d %X'; do sleep 1; done

    colors {
        statusline #ffffff
        background #323232
        inactive_workspace #32323200 #32323200 #5c5c5c
    }

    strip_workspace_numbers yes
}

说明:

• 单独设置bar字体可以避免全局字体设置 0.001 (隐藏title) 导致状态栏文字消失

• mode hide 等3行配置设置状态栏自动隐藏，并且在按下 Mod4 键时显示

• strip_workspace_numbers yes 去除状态栏内部模块的间隙

完整配置案例

综上，完整配置案例:

完整 ~/.config/sway/config

# Default config for sway
#
# Copy this to ~/.config/sway/config and edit it to your liking.
#
# Read `man 5 sway` for a complete reference.

font pango:monospace 0.001
default_border pixel 1
default_floating_border pixel 1
smart_borders on

gaps inner 0
gaps outer 0
smart_gaps on

### Variables
#
# Logo key. Use Mod1 for Alt.
set $mod Mod4
# Home row direction keys, like vim
set $left h
set $down j
set $up k
set $right l
# Your preferred terminal emulator
set $term foot
# Your preferred application launcher
set $menu wmenu-run

### Output configuration
#
# Default wallpaper (more resolutions are available in /usr/local/share/backgrounds/sway/)
output * bg /usr/local/share/backgrounds/sway/Sway_Wallpaper_Blue_1920x1080.png fill
#
# Example configuration:
#
#   output HDMI-A-1 resolution 1920x1080 position 1920,0
#
# You can get the names of your outputs by running: swaymsg -t get_outputs

### Idle configuration
#
# Example configuration:
#
exec swayidle -w \
         timeout 300 'swaylock -f -c 000000' \
         timeout 600 'swaymsg "output * power off"' resume 'swaymsg "output * power on"' \
         before-sleep 'swaylock -f -c 000000'
#
# This will lock your screen after 300 seconds of inactivity, then turn off
# your displays after another 300 seconds, and turn your screens back on when
# resumed. It will also lock your screen before your computer goes to sleep.

### Input configuration
#
# Example configuration:
#
#   input type:touchpad {
#       dwt enabled
#       tap enabled
#       natural_scroll enabled
#       middle_emulation enabled
#   }
#
#   input type:keyboard {
#       xkb_layout "eu"
#   }
#
# You can also configure each device individually.
# Read `man 5 sway-input` for more information about this section.
