* command: Use array of pointers to commandsSascha Hauer2019-10-141-12/+9
| | | | | | | | | | | | | | | | | We used to store the commands as a linker array. One problem with this is that on X86_64 for unknown reasons the linker uses a different struct alignment than the compiler, so when we use the linker to compose the array and the compiler to iterate over it we have to play tricks with manually adjusting the alignment. The other problem is that we declare the commands as const (and also put it in .rodata), but in fact we do not treat it as const: we put the commands onto a list which modifies the struct list_head list member of struct command. With this patch we no longer put the command themselves into an array, but instead create an array of pointers to the commands. This inherently solves the second issue as well.

* commands: allow <cmd>_aliases[] to be constIan Abbott2017-05-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Commands with aliases define an array of alias strings such as: static const char *<cmd>_aliases[] = { "<alias1>", NULL}; Although the elements are of type `const char *`, the elements themselves are not `const`-qualified. If the array is declared as: static const char * const <cmd>_aliases[] = { "<alias1>", NULL}; then the compiler warns about const qualifiers being discarded. This is because the `aliases` member of `struct command` is declared as `const char *aliases;`. Change the declaration of the `aliases` member of `struct command` to `const char * const *aliases;` so that it can point to a `const` array of `const char *`. Also change the declaration of the `aliases` variable in `register_command()` to avoid unnecessary type casts.

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does probably too much, but it's hard (and very cumbersome/time consuming) to break it out. What is does is this: * each command has one short description, e.g. "list MUX configuration" * made sure the short descriptions start lowercase * each command has one usage. That string contains just the options, e.g. "[-npn]". It's not part of the long help text. * that is, it doesn't say "[OPTIONS]" anymore, every usable option is listed by character in this (short) option string (the long description is in the long help text, as before) * help texts have been reworked, to make them - sometimes smaller - sometimes describe the options better - more often present themselves in a nicer format * all long help texts are now created with BUSYBOX_CMD_HELP_ macros, no more 'static const __maybe_unused char cmd_foobar_help[]' * made sure the long help texts starts uppercase * because cmdtp->name and cmdtp->opts together provide the new usage, all "Usage: foobar" texts have been removed from the long help texts * BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this is nicer in the source code * BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself * made sure no line gets longer than 77 characters * delibertely renamed cmdtp->usage, so that we can get compile-time errors (e.g. in out-of-tree modules that use register_command() * the 'help' command can now always emit the usage, even without compiled long help texts * 'help -v' gives a list of commands with their short description, this is similar like the old "help" command before my patchset * 'help -a' gives out help of all commands Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: group 'help' outputHolger Schurig2014-05-141-0/+16
| | | | | | | | | | | | | | | | | | | The old output of "help" was just producing a long list, that usually scrolled of the screen (even on a X11 terminal). This list is more compact, and also sorted by groups. The old output format (plus grouping) is now available with 'help -v'. Example: Information commands: ?, devinfo, help, iomem, meminfo, version Boot commands: boot, bootm, go, loadb, loads, loadx, loady, saves, uimage ...
