移动开发:树莓派开发环境构建

我在最初的 移动工作思考 方案中,是想采用 macOS 的 MacBook Pro来实现的: 我从2011年自费购买了MacBook Air 11" 就一直使用 Apple Atlas 家的系列产品,确实是非常成熟的软硬件融合的生态。不过,2022年3月,魔都一个多月疫情封闭在家,我开始折腾 树莓派Raspberry Pi 400 运行 sway - i3兼容Wayland compositor (基于 wayland显示服务器协议 的平铺式窗口管理器),意外发现 wayland+sway 居然能够充分释放 Raspberry Pi Atlas 的性能,这触发我思考用日常 Linux桌面 来完成所有开发运维,磨炼技术的方案。

Raspberry Pi OS

我在 Raspberry Pi Atlas 上使用过多种Linux发行版:

不过,上述第三方Linux for Raspberry Pi Atlas 各自有一些限制,对于充分发挥树莓派性能以及特有功能存在不足。所以最终,作为图形桌面,我还是回归到树莓派官方提供的 Raspberry Pi OS :

  • 官方 Raspberry Pi OS 提供了针对树莓派硬件配置的 raspi-config 工具,可以非常方便调整系统设置

  • 官方 Raspberry Pi OS 升级包含了firmware升级,可以为系统带来更多改进

  • 出现和树莓派硬件相关的问题更容易找到参考资料

安装Raspberry Pi OS

配置上海本地时区
cd /etc
sudo unlink localtime
sudo ln -s /usr/share/zoneinfo/Asia/Shanghai localtime
  • 更新系统:

APT更新整个系统
sudo apt update
sudo apt upgrade -y
  • 字符集配置UTF-8:

字符集支持UTF-8
echo "en_US.UTF-8 UTF-8" | sudo tee /etc/locale.gen
localegen
  • 安装中文字体:

apt安装文泉驿字体
sudo apt install fonts-wqy-microhei -y
apt安装sway
sudo apt install sway wofi
  • 修订 ~/.zshrc 添加以下内容方便自动启动 sway :

复制sway个人配置
if [ -z $DISPLAY ] && [ "$(tty)" = "/dev/tty1" ]; then
  exec sway
fi
  • 创建 sway 个人定制配置文件 ~/.config/sway/config :

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

### Variables
#
# Logo key. Use Mod1 for Alt.
# 我尝试过使用 Alt ,但是有些应用默认内置了 Alt 作为快捷键,可能会有冲突
set $mod Mod4

# Home row direction keys, like vim
# 结合 $mod + 移动键可以快速在4个方向上移动聚焦窗口
set $left h
set $down j
set $up k
set $right l

# Your preferred terminal emulator
# 将默认foot终端修改成qtermianl可以支持fcitx中文输入
#set $term foot
set $term qterminal

# Your preferred application launcher
# Note: pass the final command to swaymsg so that the resulting window can be opened
# on the original workspace that the command was run on.
set $menu dmenu_path | dmenu | xargs swaymsg exec --

include /etc/sway/config-vars.d/*

### Output configuration
#
# Default wallpaper (more resolutions are available in /usr/share/backgrounds/sway/)
output * bg /usr/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 * dpms off"' resume 'swaymsg "output * dpms 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.

exec_always fcitx5 -d --replace

### Input configuration
#
# Example configuration:
#
#   input "2:14:SynPS/2_Synaptics_TouchPad" {
#       dwt enabled
#       tap enabled
#       natural_scroll enabled
#       middle_emulation enabled
#   }
#
# You can get the names of your inputs by running: swaymsg -t get_inputs
# Read `man 5 sway-input` for more information about this section.

### Key bindings
#
# Basics:
#
    # Start a terminal
    bindsym $mod+Return exec $term

    # Start chromium with wayland
    bindsym $mod+o exec chromium --enable-features=UseOzonePlatform --ozone-platform=wayland --proxy-server="http://192.168.10.9:3128"

    bindsym $mod+i exec firefox

    # Kill focused window
    bindsym $mod+Shift+q kill

    # Start your launcher
    bindsym $mod+d exec $menu

    # Drag floating windows by holding down $mod and left mouse button.
    # Resize them with right mouse button + $mod.
    # Despite the name, also works for non-floating windows.
    # Change normal to inverse to use left mouse button for resizing and right
    # mouse button for dragging.
    floating_modifier $mod normal

    # Reload the configuration file
    bindsym $mod+Shift+c reload

    # Exit sway (logs you out of your Wayland session)
