Enumeration Type Documentation

enum _PurpleCmdRet
 

Enumerator:
PURPLE_CMD_RET_OK  Everything's okay.

Don't look for another command to call.

PURPLE_CMD_RET_FAILED  The command failed, but stop looking.
PURPLE_CMD_RET_CONTINUE  Continue, looking for other commands with the same name to call.


Function Documentation

PurpleCmdStatus purple_cmd_do_command PurpleConversation conv,
const gchar *  cmdline,
const gchar *  markup,
gchar **  errormsg
 

Do a command.

Normally the UI calls this to perform a command. This might also be useful if aliases are ever implemented.

Parameters:
conv The conversation the command was typed in.
cmdline The command the user typed (including all arguments) as a single string. The caller doesn't have to do any parsing, except removing the command prefix, which the core has no knowledge of. cmd should not contain any formatting, and should be in plain text (no html entities).
markup This is the same as cmd, but is the formatted version. It should be in HTML, with < > and &, at least, escaped to html entities, and should include both the default formatting and any extra manual formatting.
errormsg If the command failed errormsg is filled in with the appropriate error message. It must be freed by the caller with g_free().
Returns:
A PurpleCmdStatus indicated if the command succeeded or failed.

GList* purple_cmd_help PurpleConversation conv,
const gchar *  cmd
 

Get the help string for a command.

Returns the help strings for a given command in the form of a GList, one node for each matching command.

Parameters:
conv The conversation, or NULL for no context.
cmd The command. No wildcards accepted, but returns help for all commands if NULL.
Returns:
A GList of const char*s, which is the help string for that command.

GList* purple_cmd_list PurpleConversation conv  ) 
 

List registered commands.

Returns a GList (which must be freed by the caller) of all commands that are valid in the context of conv, or all commands, if conv is NULL. Don't keep this list around past the main loop, or anything else that might unregister a command, as the char*'s used get freed then.

Parameters:
conv The conversation, or NULL.
Returns:
A GList of const char*, which must be freed with g_list_free().

PurpleCmdId purple_cmd_register const gchar *  cmd,
const gchar *  args,
PurpleCmdPriority  p,
PurpleCmdFlag  f,
const gchar *  prpl_id,
PurpleCmdFunc  func,
const gchar *  helpstr,
void *  data
 

Register a new command with the core.

The command will only happen if commands are enabled, which is a UI pref. UIs don't have to support commands at all.

Parameters:
cmd The command. This should be a UTF8 (or ASCII) string, with no spaces or other white space.
args This tells Purple how to parse the arguments to the command for you. If what the user types doesn't match, Purple will keep looking for another command, unless the flag PURPLE_CMD_FLAG_ALLOW_WRONG_ARGS is passed in f. This string contains no whitespace, and uses a single character for each argument. The recognized characters are: 'w' Matches a single word. 'W' Matches a single word, with formatting. 's' Matches the rest of the arguments after this point, as a single string. 'S' Same as 's' but with formatting. If args is the empty string, then the command accepts no arguments. The args passed to callback func will be a NULL terminated array of null terminated strings, and will always match the number of arguments asked for, unless PURPLE_CMD_FLAG_ALLOW_WRONG_ARGS is passed.
p This is the priority. Higher priority commands will be run first, and usually the first command will stop any others from being called.
f These are the flags. You need to at least pass one of PURPLE_CMD_FLAG_IM or PURPLE_CMD_FLAG_CHAT (can may pass both) in order for the command to ever actually be called.
prpl_id This is the prpl's id string. This is only meaningful if the proper flag is set.
func This is the function to call when someone enters this command.
helpstr This is a whitespace sensitive, UTF-8, HTML string describing how to use the command. The preferred format of this string shall be the commands name, followed by a space and any arguments it accepts (if it takes any arguments, otherwise no space), followed by a colon, two spaces, and a description of the command in sentence form. No slash before the command name.
data User defined data to pass to the PurpleCmdFunc
Returns:
A PurpleCmdId. This is only used for calling purple_cmd_unregister. Returns 0 on failure.

void purple_cmd_unregister PurpleCmdId  id  ) 
 

Unregister a command with the core.

All registered commands must be unregistered, if they're registered by a plugin or something else that might go away. Normally this is called when the plugin unloads itself.

Parameters:
id The PurpleCmdId to unregister.
