构建 Peek
Peek 是一款 AUR 上人气很高的屏幕录像工具，可保存录像为 gif 动图和兼容于 html5 的 webm 视频，可以运行在 GNOME 桌面环境下。Peek 官方提供的源码里，默认包含了构建 Flatpak 应用的 YAML 文件，直接执行构建操作即可。构建 Peek 之前，需要保证 Flatpak 的版本 >= 1.4.0，如果系统的 Flatpak 版本不满足要求，同时又不能升级 Flatpak 的版本，那么可参考本文最后给出的解决方案。

| # 查看flatpak的版本
# flatpak --version
# 下载源码
# wget -O peek-1.4.0.tar.gz https://github.com/phw/peek/archive/1.4.0.tar.gz
# 解压文件
# tar -xvf peek-1.4.0.tar.gz
# 进入构建目录
# cd peek-1.4.0/data/flatpak/
# 删除旧的应用文件
# rm -rf *.flatpak
# 安装运行时依赖gnome-platform-3.34（耗时较长），依赖flatpak的版本 >= 1.4.0
# flatpak install org.gnome.Sdk/x86_64/3.34
# flatpak install org.gnome.Platform-3.34
# 执行构建脚本
# ./build.sh
# 成功构建应用后，默认会生成".flatpakref"后缀的文件，例如：peek-stable.flatpakref
# 安装构建生成应用
# flatpak install xxxx.flatpakref

构建 Peek 的 YAML 文件
构建 Flatpak 应用离不开 YAML 配置文件，作用类似 Docker 的 docker-file，如果想自定义 Peek 的构建过程，可以参考下面 YAML 配置文件。
