NAME

minput_config_command - Configure the key sequence of an input method command.

SYNOPSIS

int minput_config_command (MSymbol language, MSymbol name, MSymbol command, MPlist * keyseqlist)

DESCRIPTION

Configure the key sequence of an input method command.

The minput_config_command() function assigns a list of key sequences keyseqlist to the command command of the input method specified by language and name.

If keyseqlist is a non-empty plist, it must be a list of key sequences, and each key sequence must be a plist of symbols.

If keyseqlist is an empty plist, any configuration and customization of the command are cancelled, and default key sequences become effective.

If keyseqlist is NULL, the configuration of the command is canceled, and the original key sequences (what saved in per-user customization file, or the default one) become effective.

In the latter two cases, command can be Mnil to make all the commands of the input method the target of the operation.

If name is Mnil, this function configures the key assignment of a global command, not that of a specific input method.

The configuration takes effect for input methods opened or re-opened later in the current session. In order to make the configuration take effect for the future session, it must be saved in a per-user customization file by the function minput_save_config().

RETURN VALUE

If the operation was successful, this function returns 0, otherwise returns -1. The operation fails in these cases:

keyseqlist is not in a valid form.
command is not available for the input method.
language and name do not specify an existing input method.

Example:

/* Add 'C-x u' to the 'start' command of Unicode input method.  */
{
  MSymbol start_command = msymbol ('start');
  MSymbol unicode = msymbol ('unicode');
  MPlist *cmd, *plist, *key_seq_list, *key_seq;
  /* At first get the current key-sequence assignment.  */
  cmd = minput_get_command (Mt, unicode, start_command);
  if (! cmd)
    {
      /* The input method does not have the command 'start'.  Here
         should come some error handling code.  */
    }
  /* Now CMD == ((start DESCRIPTION STATUS KEY-SEQUENCE ...) ...).
     Extract the part (KEY-SEQUENCE ...).  */
  plist = mplist_next (mplist_next (mplist_next (mplist_value (cmd))));
  /* Copy it because we should not modify it directly.  */
  key_seq_list = mplist_copy (plist);
  
  key_seq = mplist();
  mplist_add (key_seq, Msymbol, msymbol ('C-x'));
  mplist_add (key_seq, Msymbol, msymbol ('u'));
  mplist_add (key_seq_list, Mplist, key_seq);
  m17n_object_unref (key_seq);
  minput_config_command (Mt, unicode, start_command, key_seq_list);
  m17n_object_unref (key_seq_list);
}
