* Makefile (SRCS): Add vcons-scrollback.c.
* vcons-scrollback.c: New file.
* cons.h (struct vcons): Add SCROLLING member.
* file-changed.c: Include <assert.h>.
(cons_S_file_changed): Be careful to take VCONS->scrolling into
account when doing clipping and scrolling.
* cons-switch.c: Roll back to earlier version with vcons ->
vcons_entry adjustments. The user is now expected to hold a
reference to the VCONS.
* cons.h: Fix prototype, too.
* vcons-open.c (cons_vcons_open): Initialize VCONS->lock,
VCONS->input and VCONS->display.
* vcons-remove.c: New file.
* Makefile (SRCS): Add vcons-destroy.c.
* cons.h: New type vcons_list_t.
(struct vcons_list): New structure.
(struct cons_notify): Remove VCONS member.
(struct vcons): Remove members NEXT, PREV and NOTIFY. Add the
notify structure to the top to make it possible to use a vcons as
a port. New member VCONS_ENTRY.
(struct cons): Change type of members vcons_list and vcons_last to
vcons_list_t. Remove member active.
(cons_vcons_add): Change prototype to match new definition.
(cons_vcons_remove): Likewise.
(cons_switch): Likewise.
(cons_lookup): Likewise.
(cons_vcons_open): Likewise.
(cons_vcons_destroy): New prototype.
* cons-lookup.c (cons_lookup): Change type of R_VCONS argument
vcons_list_t. Change type of previous_vcons and vcons variables
to vcons_list_t. Append _entry to all these variables.
Don't allocate and initialize a vcons_t, but a vcons_list_t.
After this has been added to the list, call cons_vcons_add.
* cons-switch.c: Do not include <error.h>
(cons_switch): Add arguments ACTIVE_ID and R_VCONS. New variable
ERR and VCONS_ENTRY. Remove variable ACTIVE. Do not keep track
of active console. Instead, look it up using ACTIVE_ID. Lock the
returned console. Call cons_vcons_open, not cons_vcons_activate.
* dir-changed.c (add_one): Change VCONS to VCONS_ENTRY and its
type from vcons_t to vcons_list_t to follow cons_lookup change.
(lookup_one): Likewise.
(cons_S_dir_changed): Likewise.
* file-changed.c (cons_S_file_changed): Cast NOTIFY to VCONS.
Check that NOTIFY->cons is not set instead that NOTIFY->vcons is.
* init-init.c (cons_init): Pass cons_vcons_destroy as
clean_routine to ports_create_class.
Don't initialize CONS->active, nor DIR_NOTIFY_PORT->vcons.
* vcons-add.c (cons_vcons_add): Change argument VCONS to CONS and
VCONS_ENTRY. Don't do anything here (the user must implement it
all).
* vcons-close.c: Don't include <errno.h>, <unistd.h>, <stdio.h>,
<sys/mman.h>, <sys/fcntl.h>, <mach.h>. Include <assert.h>,
<hurd/ports.h> and <cthreads.h>.
(cons_vcons_close): Clear VCONS->vcons_entry->vcons. Derefence
and destroy VCONS.
* vcons-open.c (cons_vcons_open): Change arguments from VCONS to
CONS, VCONS_ENTRY and R_VCONS. New variable VCONS. Set up VCONS
as a port, and request notification messages on that.
* vcons-remove.c: Do not include <errno.h>.
(cons_vcons_remove): Assert that VCONS_ENTRY does not have an open
VCONS.
2002-08-28 Marcus Brinkmann <marcus@gnu.org>
* file-changed.c (cons_S_file_changed): Take NEW_CUR_LINE modulo
VCONS->state.screen.lines where appropriate. Adapt calculation of
SCROLLING, and limit it to the screen size.
Only scroll at all if there is something to scroll.
Fix calculation of scrolled-in area.
* vcons-refresh.c (cons_vcons_refresh): Take
VCONS->state.screen.cur_line modulo VCONS->state.screen.lines.
2002-08-22 Marcus Brinkmann <marcus@gnu.org>
* demuxer.c, init-init.c, init-loop.c, opts-version.c,
extra-version.c, dir-changed.c, file-changed.c,
opts-std-startup.c, cons-lookup.c, cons-switch.c, vcons-remove.c,
vcons-add.c, vcons-open.c, vcons-close.c, vcons-refresh.c, priv.h,
mutations.h, cons.h: New files.
