There's no particular date beyond Real Soon Now (i.e. when it can be finished). The tracking bug is https://github.com/fish-shell/fish-shell/issues/1781 I'd like to get a beta done but https://github.com/fish-shell/fish-shell/issues/1730 needs resolution first. > b.. 2.

I really REALLY REALLY REALLY want to use fish > shell under DragonFlyBSD for a new website project. I can reproduce this on DragonFlyBSD, so that's exciting. Turning up the debugging reveals that there is a parse error in fish (that's why you get that "fish:" line printed - there's a problem with printing the full error message). AFAICT, the problem lies in utf2wcs(). On working platforms, for the standard first line of the fishd file, utf2wcs returns: L"# This file is automatically generated by the fishd universal variable daemon." On broken platforms, the string returned is L"\000\000\376\377\000\000\000#\000\000\000 \000\000\000T\000\000\000h\000\000\000i\000\000\000s\000\000\000 \000\000\000f\000\000\000i\000\000\000l\000\000\000e\000\000\000 ..." There's an extra byte there and I'm not sure where it came from. Anyway, I'm not 100% convinced this is what actually causes the problem. More investigation is probably required, but I'm out of time for today.
