A GTK4 ssh-askpass in Zig

I run hardened Gentoo on my laptop, and most of the time I never touch ssh-askpass because I’m using -sk keys for most of the systems. There is one class of situation where I do need it, though, which is when a program wants an SSH key passphrase for a regular ED25519 key, but has no terminal to read it from. The usual case is go get, or the go toolchain in general, fetching a private module over SSH during a build that runs without a TTY. OpenSSH can’t prompt on a pipe, so it runs whatever SSH_ASKPASS points at and puts the passphrase prompt in a window instead. For years I had nothing installed for that and had to work around these scenarios. The main reason for that is what Gentoo’s Portage offers:  ~ emerge -s ssh-askpass [ Results for search key : ssh-askpass ] Searching... * kde-plasma/ksshaskpass Latest version available: 6.6.6 Latest version installed: [ Not Installed ] Size of files: 32 KiB Homepage: https://kde.org/plasma-desktop https://invent.kde.org/plasma/ksshaskpass…
