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-set-buffer.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'cmd-set-buffer.c') diff --git a/cmd-set-buffer.c b/cmd-set-buffer.c index e3b1656b..46450e21 100644 --- a/cmd-set-buffer.c +++ b/cmd-set-buffer.c @@ -27,7 +27,7 @@ * Add or set a paste buffer. */ -enum cmd_retval cmd_set_buffer_exec(struct cmd *, struct cmd_ctx *); +enum cmd_retval cmd_set_buffer_exec(struct cmd *, struct cmd_q *); const struct cmd_entry cmd_set_buffer_entry = { "set-buffer", "setb", @@ -40,7 +40,7 @@ const struct cmd_entry cmd_set_buffer_entry = { }; enum cmd_retval -cmd_set_buffer_exec(struct cmd *self, struct cmd_ctx *ctx) +cmd_set_buffer_exec(struct cmd *self, struct cmd_q *cmdq) { struct args *args = self->args; u_int limit; @@ -60,14 +60,14 @@ cmd_set_buffer_exec(struct cmd *self, struct cmd_ctx *ctx) buffer = args_strtonum(args, 'b', 0, INT_MAX, &cause); if (cause != NULL) { - ctx->error(ctx, "buffer %s", cause); + cmdq_error(cmdq, "buffer %s", cause); free(cause); free(pdata); return (CMD_RETURN_ERROR); } if (paste_replace(&global_buffers, buffer, pdata, psize) != 0) { - ctx->error(ctx, "no buffer %d", buffer); + cmdq_error(cmdq, "no buffer %d", buffer); free(pdata); return (CMD_RETURN_ERROR); } -- cgit v1.2.3
