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:

           {
             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);
