From 60ba4641d61ba65943ac7a8c800e82d6665ee11f Mon Sep 17 00:00:00 2001 From: Zachary T Welch Date: Sat, 21 Nov 2009 13:59:51 -0800 Subject: add command registration chaining Adds the ability to chain registration structures. Modules can define a command with the 'chain' and 'num_chain' fields defined in their registration table, and the register_commands() function will initialize these commands. If the registration record creates a new command, then the chained commands are created under it; otherwise, they are created in the same context as the other commands (i.e. the parent argument). --- src/helper/command.h | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'src/helper/command.h') diff --git a/src/helper/command.h b/src/helper/command.h index 7baa92d..6e3e93a 100644 --- a/src/helper/command.h +++ b/src/helper/command.h @@ -202,10 +202,18 @@ struct command_registration { const char *help; /// a string listing the options and arguments, required or optional const char *usage; + + /** + * If non-NULL, the commands in @c chain will be registered in + * the same context and scope of this registration record. + * This allows modules to inherit lists commands from other + * modules. + */ + const struct command_registration *chain; }; /// Use this as the last entry in an array of command_registration records. -#define COMMAND_REGISTRATION_DONE { .name = NULL } +#define COMMAND_REGISTRATION_DONE { .name = NULL, .chain = NULL } /** * Register a command @c handler that can be called from scripts during @@ -238,7 +246,10 @@ struct command* register_command(struct command_context *cmd_ctx, /** * Register one or more commands in the specified context, as children - * of @c parent (or top-level commends, if NULL). + * of @c parent (or top-level commends, if NULL).
