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-command-prompt.c | 17 +++++------------ 1 file changed, 5 insertions(+), 12 deletions(-) (limited to 'cmd-command-prompt.c') diff --git a/cmd-command-prompt.c b/cmd-command-prompt.c index 3a43b24f..3b773316 100644 --- a/cmd-command-prompt.c +++ b/cmd-command-prompt.c @@ -31,7 +31,7 @@ void cmd_command_prompt_key_binding(struct cmd *, int); int cmd_command_prompt_check(struct args *); -enum cmd_retval cmd_command_prompt_exec(struct cmd *, struct cmd_ctx *); +enum cmd_retval cmd_command_prompt_exec(struct cmd *, struct cmd_q *); int cmd_command_prompt_callback(void *, const char *); void cmd_command_prompt_free(void *); @@ -85,7 +85,7 @@ cmd_command_prompt_key_binding(struct cmd *self, int key) } enum cmd_retval -cmd_command_prompt_exec(struct cmd *self, struct cmd_ctx *ctx) +cmd_command_prompt_exec(struct cmd *self, struct cmd_q *cmdq) { struct args *args = self->args; const char *inputs, *prompts; @@ -94,7 +94,7 @@ cmd_command_prompt_exec(struct cmd *self, struct cmd_ctx *ctx) char *prompt, *ptr, *input = NULL; size_t n; - if ((c = cmd_find_client(ctx, args_get(args, 't'), 0)) == NULL) + if ((c = cmd_find_client(cmdq, args_get(args, 't'), 0)) == NULL) return (CMD_RETURN_ERROR); if (c->prompt_string != NULL) @@ -150,7 +150,6 @@ cmd_command_prompt_callback(void *data, const char *s) struct cmd_command_prompt_cdata *cdata = data; struct client *c = cdata->c; struct cmd_list *cmdlist; - struct cmd_ctx *ctx; char *cause, *new_template, *prompt, *ptr; char *input = NULL; @@ -175,7 +174,7 @@ cmd_command_prompt_callback(void *data, const char *s) return (1); } - if (cmd_string_parse(new_template, &cmdlist, &cause) != 0) { + if (cmd_string_parse(new_template, &cmdlist, NULL, 0, &cause) != 0) { if (cause != NULL) { *cause = toupper((u_char) *cause); status_message_set(c, "%s", cause); @@ -184,14 +183,8 @@ cmd_command_prompt_callback(void *data, const char *s) return (0); } - ctx = cmd_get_ctx(NULL, c); - ctx->error = key_bindings_error; - ctx->print = key_bindings_print; - ctx->info = key_bindings_info; - - cmd_list_exec(cmdlist, ctx); + cmdq_run(c->cmdq, cmdlist); cmd_list_free(cmdlist); - cmd_free_ctx(ctx); if (c->prompt_callbackfn != (void *) &cmd_command_prompt_callback) return (1); -- cgit
