* redisplay-xlike-inc.c (console_type_create_redisplay_XLIKE):
Move lots more code into redisplay-xlike-inc.c. Use macros to
isolate the code that differs among X vs. GTK, to reduce the need
for ifdefs in the middle of the code. Now, redisplay-x.c and
redisplay-gtk.c only contain a few functions whose implementation
is completely different from one to the other, or which are not
present at all in one of them.
GTK code not currently tested, but it has bitrotted somewhat
any. Doing this will help keep it less bitrotty.
* depend: Regenerate.

| 29 | |
| 30 ;;; Commentary: | |
| 31 | |
| 32 ;; This file is dumped with XEmacs. | |
| 33 | |
| 502 | 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 ;; | |
| 62 ;; The job of the code here is to process the remaining command-line | |
| 63 ;; args, set up the various paths, locate where all the packages are | |
| 64 ;; and set things up for them (initialize the load path, read in the | |
| 65 ;; autoloads, etc.), read in the init files, display the splash | |
| 66 ;; screen, and set up any remaining environment-dependent variables. | |

| 335 is messing things up, or when running XEmacs in | |
| 336 batch mode. | |

| 776 | 339 -no-packages Pretend like the packages don't exist. Don't put |
| 340 any packages in the load path or set up any package | |
| 969 | 341 autoloads. Also implies `-vanilla'. Use this when |
| 776 | 342 running XEmacs in batch mode when you aren't using |
| 343 any functionality in packages and want to make sure | |
| 344 that you get no interference from packages | |
| 345 (e.g. Lisp files that shadow core Lisp files). | |
| 346 -no-early-packages Do not process early packages. | |
| 771 | 347 -debug-paths Display info about the runtime values of various |
| 348 directory variables (e.g. for loading packages). | |
| 349 -no-site-modules Do not search site-modules directories for modules | |
| 350 at startup. Only applies when modules support is | |
| 351 compiled into XEmacs. | |
| 352 | |
| 353 Encoding options: | |
| 354 | |
| 355 -eol Turn on EOL detection (only applies to Unix, no | |
