From 3964309c67a683e5132662e38b5ff932af5cbeea Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Sat, 23 Feb 2013 22:25:58 +0000 Subject: Add a command queue to standardize and simplify commands that call other commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client. --- cmd-list-commands.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'cmd-list-commands.c') diff --git a/cmd-list-commands.c b/cmd-list-commands.c index f816221a..1bf6e703 100644 --- a/cmd-list-commands.c +++ b/cmd-list-commands.c @@ -24,7 +24,7 @@ * List all commands with usages. */ -enum cmd_retval cmd_list_commands_exec(struct cmd *, struct cmd_ctx *); +enum cmd_retval cmd_list_commands_exec(struct cmd *, struct cmd_q *); const struct cmd_entry cmd_list_commands_entry = { "list-commands", "lscm", @@ -37,16 +37,16 @@ const struct cmd_entry cmd_list_commands_entry = { }; enum cmd_retval -cmd_list_commands_exec(unused struct cmd *self, struct cmd_ctx *ctx) +cmd_list_commands_exec(unused struct cmd *self, struct cmd_q *cmdq) { const struct cmd_entry **entryp; for (entryp = cmd_table; *entryp != NULL; entryp++) { if ((*entryp)->alias != NULL) { - ctx->print(ctx, "%s (%s) %s", (*entryp)->name, + cmdq_print(cmdq, "%s (%s) %s", (*entryp)->name, (*entryp)->alias, (*entryp)->usage); } else { - ctx->print(ctx, "%s %s", (*entryp)->name, + cmdq_print(cmdq, "%s %s", (*entryp)->name, (*entryp)->usage); } } -- cgit
