21 // cmd.h -- Command buffer and command execution
23 //===========================================================================
27 Any number of commands can be added in a frame, from several different sources.
28 Most commands come from either keybindings or console line input, but remote
29 servers can also send across commands and entire text files can be execed.
31 The + command line options are also added to the command buffer.
33 The game starts with a Cbuf_AddText ("exec quake.rc\n"); Cbuf_Execute ();
40 void Cbuf_Init (void);
41 // allocates an initial text buffer that will grow as needed
43 void Cbuf_AddText (char *text);
44 // as new commands are generated from the console or keybindings,
45 // the text is added to the end of the command buffer.
47 void Cbuf_InsertText (char *text);
48 // when a command wants to issue other commands immediately, the text is
49 // inserted at the beginning of the buffer, before any remaining unexecuted
52 void Cbuf_Execute (void);
53 // Pulls off \n terminated lines of text from the command buffer and sends
54 // them through Cmd_ExecuteString. Stops when the buffer is empty.
55 // Normally called once per frame, but may be explicitly invoked.
56 // Do not call inside a command function!
58 //===========================================================================
62 Command execution takes a null terminated string, breaks it into tokens,
63 then searches for a command or variable that matches the first token.
65 Commands can come from three sources, but the handler functions may choose
66 to dissallow the action or forward it to a remote server if the source is
71 typedef void (*xcommand_t) (void);
75 src_client, // came in over a net connection as a clc_stringcmd
76 // host_client will be valid during this state.
77 src_command // from the command buffer
80 extern cmd_source_t cmd_source;
84 void Cmd_AddCommand (char *cmd_name, xcommand_t function);
85 // called by the init functions of other parts of the program to
86 // register commands and functions to call for them.
87 // The cmd_name is referenced later, so it should not be in temp memory
89 qboolean Cmd_Exists (char *cmd_name);
90 // used by the cvar code to check for cvar / command name overlap
92 char *Cmd_CompleteCommand (char *partial);
93 // attempts to match a partial command for automatic command line completion
94 // returns NULL if nothing fits
96 int Cmd_CompleteAliasCountPossible (char *partial);
98 char **Cmd_CompleteAliasBuildList (char *partial);
100 int Cmd_CompleteCountPossible (char *partial);
102 char **Cmd_CompleteBuildList (char *partial);
104 char *Cmd_CompleteAlias (char *partial);
106 // Enhanced console completion by Fett erich@heintz.com
108 // Added by EvilTypeGuy eviltypeguy@qeradiant.com
111 char *Cmd_Argv (int arg);
112 char *Cmd_Args (void);
113 // The functions that execute commands get their parameters with these
114 // functions. Cmd_Argv () will return an empty string, not a NULL
115 // if arg > argc, so string operations are always safe.
117 int Cmd_CheckParm (char *parm);
118 // Returns the position (1 to argc-1) in the command's argument list
119 // where the given parameter apears, or 0 if not present
121 //void Cmd_TokenizeString (char *text);
122 // Takes a null terminated string. Does not need to be /n terminated.
123 // breaks the string up into arg tokens.
125 void Cmd_ExecuteString (char *text, cmd_source_t src);
126 // Parses a single line of text into arguments and tries to execute it.
127 // The text can come from the command buffer, a remote client, or stdin.
129 void Cmd_ForwardToServer (void);
130 // adds the current command line as a clc_stringcmd to the client message.
131 // things like godmode, noclip, etc, are commands directed to the server,
132 // so when they are typed in at the console, they will need to be forwarded.
134 void Cmd_Print (char *text);
135 // used by command functions to send output to either the graphics console or
136 // passed as a print message to the client
