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 Cmd_Init_Commands (void);
45 void Cbuf_Shutdown (void);
47 void Cbuf_AddText (const char *text);
48 // as new commands are generated from the console or keybindings,
49 // the text is added to the end of the command buffer.
51 void Cbuf_InsertText (const char *text);
52 // when a command wants to issue other commands immediately, the text is
53 // inserted at the beginning of the buffer, before any remaining unexecuted
56 void Cbuf_Execute (void);
57 // Pulls off \n terminated lines of text from the command buffer and sends
58 // them through Cmd_ExecuteString. Stops when the buffer is empty.
59 // Normally called once per frame, but may be explicitly invoked.
60 // Do not call inside a command function!
62 //===========================================================================
66 Command execution takes a null terminated string, breaks it into tokens,
67 then searches for a command or variable that matches the first token.
69 Commands can come from three sources, but the handler functions may choose
70 to dissallow the action or forward it to a remote server if the source is
75 typedef void (*xcommand_t) (void);
79 src_client, // came in over a net connection as a clc_stringcmd
80 // host_client will be valid during this state.
81 src_command // from the command buffer
84 extern cmd_source_t cmd_source;
87 void Cmd_Shutdown (void);
89 void Cmd_AddCommand (const char *cmd_name, xcommand_t function);
90 // called by the init functions of other parts of the program to
91 // register commands and functions to call for them.
92 // The cmd_name is referenced later, so it should not be in temp memory
94 qboolean Cmd_Exists (const char *cmd_name);
95 // used by the cvar code to check for cvar / command name overlap
97 const char *Cmd_CompleteCommand (const char *partial);
98 // attempts to match a partial command for automatic command line completion
99 // returns NULL if nothing fits
101 int Cmd_CompleteAliasCountPossible (const char *partial);
103 const char **Cmd_CompleteAliasBuildList (const char *partial);
105 int Cmd_CompleteCountPossible (const char *partial);

109 const char *Cmd_CompleteAlias (const char *partial);
111 // Enhanced console completion by Fett erich@heintz.com

116 const char *Cmd_Argv (int arg);
117 const char *Cmd_Args (void);
118 // The functions that execute commands get their parameters with these
119 // functions. Cmd_Argv () will return an empty string, not a NULL
120 // if arg > argc, so string operations are always safe.
122 int Cmd_CheckParm (const char *parm);
123 // Returns the position (1 to argc-1) in the command's argument list
124 // where the given parameter apears, or 0 if not present
126 //void Cmd_TokenizeString (char *text);
127 // Takes a null terminated string. Does not need to be /n terminated.
128 // breaks the string up into arg tokens.
130 void Cmd_ExecuteString (const char *text, cmd_source_t src);
131 // Parses a single line of text into arguments and tries to execute it.
132 // The text can come from the command buffer, a remote client, or stdin.
134 void Cmd_ForwardStringToServer (const char *s);
135 // adds the string as a clc_stringcmd to the client message.
136 // (used when there is no reason to generate a local command to do it)
138 void Cmd_ForwardToServer (void);
139 // adds the current command line as a clc_stringcmd to the client message.
140 // things like godmode, noclip, etc, are commands directed to the server,
141 // so when they are typed in at the console, they will need to be forwarded.
143 void Cmd_Print(const char *text);
144 // used by command functions to send output to either the graphics console or
145 // passed as a print message to the client
