开发者用Zig和GTK4打造轻量级SSH密码输入工具

一位开发者使用Zig 0.16和GTK4编写了ssh-askpass-zigtk，这是一款SSH密码输入工具，通过手写GTK绑定设计避免了对X11的依赖1。该项目旨在解决Gentoo软件包仓库中现有SSH askpass工具的问题——这些工具往往需要拉入X11或完整KDE栈作为依赖1。

该工具支持多种Linux架构的交叉编译，包括x86_64、aarch64、armv7、riscv64、powerpc64le、i386、loongarch64和s390x1，并提供预编译二进制版本1。项目要求OpenSSH 8.4及以上版本以支持SSH_ASKPASS_REQUIRE=prefer功能1。开发者指出，由于GTK3中的gdk_seat_grab界面在GTK4已被移除，且Wayland不支持键盘抓取，因此GNOME_SSH_ASKPASS_GRAB_SERVER和GNOME_SSH_ASKPASS_GRAB_POINTER变量在新版本中无效1。项目代码托管在tty.fail及GitHub镜像上1。

A developer has created ssh-askpass-zigtk, an SSH password prompt utility built using Zig 0.16 and GTK4 1. The tool addresses a specific packaging challenge in Gentoo's software repository, where existing SSH askpass implementations require either X11 dependencies or a complete KDE desktop environment stack 1.

The project uses hand-written GTK bindings to minimize dependencies, avoiding the need for full X11 integration 1. The tool supports cross-compilation across multiple Linux architectures, including x86_64, aarch64, armv7, riscv64, powerpc64le, i386, loongarch64, and s390x 1. It is compatible with OpenSSH version 8.4 and later, leveraging the SSH_ASKPASS_REQUIRE=prefer functionality 1. The project is available on tty.fail with a GitHub mirror 1.

According to the developer's documentation, certain features from GTK3 have been removed in GTK4; specifically, the gdk_seat_grab interface is no longer available 1. Additionally, Wayland does not support keyboard grabbing, rendering the GNOME_SSH_ASKPASS_GRAB_SERVER and GNOME_SSH_ASKPASS_GRAB_POINTER environment variables ineffective 1. Pre-compiled binary versions are provided for users 1.
