From 20636d956dd36c1f14152569a4d44a50eea9083d Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Sun, 24 Mar 2013 09:54:10 +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-display-message.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'cmd-display-message.c') diff --git a/cmd-display-message.c b/cmd-display-message.c index 05c3a408..7f31d7e2 100644 --- a/cmd-display-message.c +++ b/cmd-display-message.c @@ -27,7 +27,7 @@ * Displays a message in the status line. */ -enum cmd_retval cmd_display_message_exec(struct cmd *, struct cmd_ctx *); +enum cmd_retval cmd_display_message_exec(struct cmd *, struct cmd_q *); const struct cmd_entry cmd_display_message_entry = { "display-message", "display", @@ -41,7 +41,7 @@ const struct cmd_entry cmd_display_message_entry = { }; enum cmd_retval -cmd_display_message_exec(struct cmd *self, struct cmd_ctx *ctx) +cmd_display_message_exec(struct cmd *self, struct cmd_q *cmdq) { struct args *args = self->args; struct client *c; @@ -56,17 +56,17 @@ cmd_display_message_exec(struct cmd *self, struct cmd_ctx *ctx) size_t len; if (args_has(args, 't')) { - wl = cmd_find_pane(ctx, args_get(args, 't'), &s, &wp); + wl = cmd_find_pane(cmdq, args_get(args, 't'), &s, &wp); if (wl == NULL) return (CMD_RETURN_ERROR); } else { - wl = cmd_find_pane(ctx, NULL, &s, &wp); + wl = cmd_find_pane(cmdq, NULL, &s, &wp); if (wl == NULL) return (CMD_RETURN_ERROR); } if (args_has(args, 'F') && args->argc != 0) { - ctx->error(ctx, "only one of -F or argument must be given"); + cmdq_error(cmdq, "only one of -F or argument must be given"); return (CMD_RETURN_ERROR); } @@ -77,7 +77,7 @@ cmd_display_message_exec(struct cmd *self, struct cmd_ctx *ctx) template = DISPLAY_MESSAGE_TEMPLATE; ft = format_create(); - if ((c = cmd_find_client(ctx, args_get(args, 'c'), 1)) != NULL) + if ((c = cmd_find_client(cmdq, args_get(args, 'c'), 1)) != NULL) format_client(ft, c); format_session(ft, s); format_winlink(ft, s, wl); @@ -89,11 +89,11 @@ cmd_display_message_exec(struct cmd *self, struct cmd_ctx *ctx) msg = format_expand(ft, out); if (args_has(self->args, 'p')) - ctx->print(ctx, "%s", msg); + cmdq_print(cmdq, "%s", msg); else status_message_set(c, "%s", msg); - free(msg); format_free(ft); + return (CMD_RETURN_NORMAL); } -- cgit v1.2.3
