Thus, there is the "ns_no_defaults" hack in emacs.c. It would be easier to do this cleanly if other platforms choose to implement it as well. ^ permalink raw reply [flat|nested] 19+ messages in thread

(untested). That works, but it is awfully ugly if you have many Registry settings. I'd like a simple way to just say "no Registry settings AT ALL". I can workaround now by running Emacs with a script doing emacs -Q -xrm Emacs.Geometry: -xrm Emacs.Foreground: -xrm Emacs.Background: but it is a PITA.

It's simple. In my patch, "emacs -Q -xrm resource" won't obey -xrm either, but it is trivially easy to change it to allow that, if desired (it's just moving the "if() ... return" down a few lines in w32reg:x_get_resource_string). > I think that's OK, but the double-parsing of -Q is not > very satisfactory.

I had in fact done that before (though I reused instead the currently undocumented emacs-quick-startup variable that startup.el uses now). But I didn't want to mess with the processing of -Q/--quick in the HAVE_NS block immediately following: #ifdef HAVE_NS ns_alloc_autorelease_pool(); if (!noninteractive) { char *tmp; display_arg = 4; if (argmatch (argv, argc, "-q", "--no-init-file", 6, NULL, &skip_args)) { ns_no_defaults = 1; skip_args--; } if (argmatch (argv, argc, "-Q", "--quick", 5, NULL, &skip_args)) { ns_no_defaults = 1; skip_args--; } #ifdef NS_IMPL_COCOA if (skip_args < argc) { if (!strncmp(argv[skip_args], "-psn", 4)) { skip_args += 1; chdir (getenv ("HOME")); } else if (skip_args+1 < argc && !strncmp(argv[skip_args+1], "-psn", 4)) { skip_args += 2; chdir (getenv ("HOME")); } } #endif /* This used for remote operation.. not fully implemented yet. */ if (argmatch (argv, argc, "-_NSMachLaunch", 0, 3, &tmp, &skip_args)) display_arg = 4; else if (argmatch (argv, argc, "-MachLaunch", 0, 3, &tmp, &skip_args)) display_arg = 4; else if (argmatch (argv, argc, "-macosx", 0, 2, NULL, &skip_args)) display_arg = 4; else if (argmatch (argv, argc, "-NSHost", 0, 3, &tmp, &skip_args)) display_arg = 4; } #endif /* HAVE_NS */ I think intermixing this with the new processing of -Q/--quick will lead to uglier code...

OTOH, it's just the same behavior as under POSIX where environment variables are not provided via xrm but directly (and -Q does not override them). For HOME settings, I think it's TRT. For other variables, it's less clear, but I think it's OK for now. >> Well, I'm not sure if it would be useful, but the name seems to reflect >> more precisely the effect of the variable, and indeed it can later on >> be changed from Lisp, tho it's not clear whether that would be useful. > BTW, the question of whether "emacs -Q -xrm myresouce" should obey > myresource or not is still open.

On Windows it is trivial, so I'll add it to my patch. OK, there it goes. I've added the "if (...) return" code to xrdb.c:x_get_string_resource, so I'd be glad if someone on GNU/Linux can test that it works as expected (or at least that it does nothing bad). Once that is verified and you've installed your startup.el patch, I can go on installing this and then Adrian can tweak for NextStep and the X integration can be ironed out.
