34 ;; It handles the all aspects of startup once the C code has finished
|
|
|
35 ;; initializing itself. Entry from C is through the function set in
|
|
|
36 ;; the `top-level' variable, which is normally `normal-top-level'. At
|
|
|
37 ;; the point that `normal-top-level' has been invoked:
|
|
|
38 ;;
|
|
|
39 ;; (1) the dumped Elisp files are available. Either they were loaded
|
|
|
40 ;; during this invocation of temacs and it was then converted to
|
|
|
41 ;; XEmacs using the run-temacs mechanism, or (more likely) the
|
|
|
42 ;; loadup and dumping occurred at some point in the past and we
|
|
|
43 ;; just read in the dumped data.
|
|
|
44 ;;
|
|
|
45 ;; (2) All C subsystems have been initialized.
|
|
|
46 ;;
|
|
|
47 ;; (3) A "stream" device has been created, which does I/O over stdin
|
|
|
48 ;; and stdout. This is the only device we have available and our
|
|
|
49 ;; only means of communication, other than disk files.
|
|
|
50 ;;
|
|
|
51 ;; (4) The command-line arguments have been sorted according to
|
|
|
52 ;; priority specs (this implies that the names of all arguments
|
|
|
53 ;; must be hard-coded into emacs.c), and certain low-level
|
|
|
54 ;; arguments such as -sd, -t, -nd, -nw, -batch, etc. have been
|
|
|
55 ;; processed by main_1() and removed. (NOTE: main_1() is the name
|
|
|
56 ;; in the source code, but in the object file it has some other
|
|
|
57 ;; name, such as xemacs_21_2_34_mips_sgi_irix6().) Certain other
|
|
|
58 ;; arguments such as -version and -help are partially-processed,
|
|
|
59 ;; triggering some special behavior but being left on the list for
|
|
|
60 ;; further processing by the Lisp code.

61 ;;

|
|
322 -user-init-directory <directory>
|
|
|
323 Use <directory> as init directory.
|
|
|
324 -user <user> Load user's init file instead of your own.
|
|
|
325 -u <user> Same as -user.
|
|
|
326 -no-site-file Do not load the site-specific init file
|
|
|
327 (site-start.el).
|
|
|
328
|
|
|
329 Package/module options:
|
|
|
330
|
|
|
331 -vanilla Equivalent to -q -no-site-file -no-early-packages.
|
|
776
|
332 Useful if you think some user-init or site-init code
|
|
|
333 is messing things up, or when running XEmacs in
|
|
|
334 batch mode.
|
|
428
|
335 -no-autoloads Do not load global symbol files (auto-autoloads) at
|
|
|
336 startup. Also implies `-vanilla'.
|
|
776
|
337 -no-packages Pretend like the packages don't exist. Don't put
|
|
|
338 any packages in the load path or set up any package
|
|
969
|
339 autoloads. Also implies `-vanilla'. Use this when
|
|
776
|
340 running XEmacs in batch mode when you aren't using
|
|
|
341 any functionality in packages and want to make sure
|
|
|
342 that you get no interference from packages
|
|
|
343 (e.g. Lisp files that shadow core Lisp files).
|
|
|
344 -no-early-packages Do not process early packages.
|
|
771
|
345 -debug-paths Display info about the runtime values of various
|
|
|
346 directory variables (e.g. for loading packages).
|
|
|
347 -no-site-modules Do not search site-modules directories for modules
|
|
|
348 at startup. Only applies when modules support is
|
|
|
349 compiled into XEmacs.
|
|
|
350
|
|
|
351 Encoding options:
|
|
|
352
|
|
|
353 -eol Turn on EOL detection (only applies to Unix, no
|
|
|
354 international support; otherwise EOL detection is
|
|
|
355 already on).
|
|
|
356 -nuni Under MS Windows, disable use of the Unicode versions
|
|
|
357 of API calls. Not for Windows 95/98/ME. This is
|
|
|
358 mostly only useful for debugging purposes.
|
|
|
359

|
360 Misc:
|
|
|
361
