1999-09-05 OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>
The internal of the command handling is heavily modified, and
a new command "help" is added.
* stage1/stage1.S: Set the number of sectors for Stage 2 to 110.
* stage1/stage1_lba.S: Likewise.
* stage2/builtins.c: New file.
* stage2/Makefile.am (libgrub_a_SOURCES): Added builtins.c.
(stage2_exec_SOURCES): Likewise.
* stage2/boot.c (load_image): Return kernel_t instead int.
(bsd_boot): Change the type of the first argument to kernel_t.
* stage2/char_io.c (get_cmdline): Do not accept the argument
COMMANDS and accept the argument COMPLETION.
Print completions only if COMPLETION is non-zero.
Print the list of short docs when the command is completed.
* stage2/cmdline.c [GRUB_UTIL]: Do not include apic.h and
smp-imps.h.
(fallback): Deleted.
(password): Likewise.
(debug): Likewise.
(normal_color): Likewise.
(highlight_color): Likewise.
(print_cmdline_message): New function.
(commands): Deleted.
(debug_fs_print_func): Likewise.
(installaddr): Likewise.
(installlist): Likewise.
(installsect): Likewise.
(debug_fs_blocklist_func): Likewise.
(find_command): New function.
(init_cmdline): Initialize the data for the command-line
interface. The function to print the message is moved to
print_cmdline_message.
(enter_cmdline): Rewritten from scratch. Now deal with only the
pure command-line and the function to deal with a menu entry is
moved to run_script.
(run_script): New function.
* stage2/shared.h (PASSWORD_BUF): New macro.
(PASSWORD_BUFLEN): Likewise.
(CMDLINE_BUF): Likewise.
(CMDLINE_BUFLEN): Likewise.
(MENU_BUF): Likewise.
(MENU_BUFLEN): Likewise.
(fallback): Deleted.
(fallback_entry): Declared.
(default_entry): Likewise.
(BUILTIN_CMDLINE): New macro.
(BUILTIN_MENU): Likewise.
(BUILTIN_TITLE): Likewise.
(struct builtin): New tag.
(builtin_table): Declared.
(cmdline_t): Deleted.
(kernel_t): New type.
(kernel_type): Declared.
(grub_timeout): Likewise.
(init_builtins): Likewise.
(init_config): Likewise.
(find_command): Likewise.
(print_cmdline_message): Likewise.
(run_script): Likewise.
[!STAGE1_5] (bsd_boot): Deleted.
[!STAGE1_5] (load_image): Likewise.
[!STAGE1_5] (load_module): Likewise.
[!STAGE1_5] (load_initrd): Likewise.
* stage2/size_test: Set the maximum size of Stage 2 to 56320.
* stage2/stage2.c (grub_timeout): Deleted.
(menu_t): Likewise.
(run_menu): Changed the return type to void.
Use FALLBACK_ENTRY instead of FALLBACK.
Do not check the return value of enter_cmdline.
(run_menu) [GRUB_UTIL]: Call stop instead of returning
MENU_ABORT.
(cmain): Set MENU_ENTRIES to MENU_BUF.
Call init_config instead of clearing the variables directly.
Use CMDLINE_BUF for the command-line buffer instead of the
stack.
Adapted the analysis routine for the configuration file to the
new builtin commands interface.
Run enter_cmdline forever.
If run_menu returns, restart the loop.
1999-09-04 Pavel Roskin <pavel_roskin@geocities.com>
* docs/menu.lst: More meaningful examples. Not using (0x80,0)

@ -10,6 +10,9 @@ New in 0.5.93:
* New commands "hide" and "unhide".
* The character `=' after a command is not necessary any longer, but it
is supported for backward compatibility.
* The command "help" displays helpful information about builtin
commands.
* The command "geometry" displays the information of a drive specified.
New in 0.5.92 - 1999-07-26:
* Bug fixes (i.e. Stage 1.5 can work fine again).
