Quest multilingual x.chat.y?

[Yiv 313]

Dear community,

 

I wanted to give myself the option with expanding to an international server, so I want to script my quests multilingualable. For this, I wrote a function lang.get_text(string) which searches in a table for the entry and returns the text in the language the user has chosen.

Everything's fine but if I try this:

when npc_list.BIOLOGIST.chat.lang.get_text("test_quest_chat") begin

The compiler arborts with this:

 

SHLVL=1:25:when doesn't have begin-end clause. (lang)
Abort trap (core dumped)

 

Someone may help me?

 

Regards

It's not possible to use functiones on that kind of things, e.g:

when XXXXX.chat.text[pc.getf("lang", "lang")][1] begin

The better way (and I guess the unique) to do that is using click event instead of chat. But now with the source I guess all it's possible.

You can allow for functions or variables on chat by tweaking the qc.cc file - Did it first day with source to allow precisely that.

Fair warning, though. As with any parser, at first it's confusing to look at the source xD

 

You want to change before here:

current_when_argument += os.str();

And what I did was implement a recursive check for parenthesis to allow arguments on said function call (The parenthesis for the func call are the only real problem that needs to be changed). It's not very tested since we didn't end up using it, but I can confirm that my initial tests worked, compiled and displayed ingame.

 

This is what I added if I recall correctly:

//Accept functions as valid arguments
const char    TK_OPEN_PARENTHESIS = '(',
            TK_CLOSE_PARENTHESIS = ')';

if (lexstate.lookahead.token == TK_OPEN_PARENTHESIS)
{
    int depth = 0;
    while(lexstate.lookahead.token != TK_CLOSE_PARENTHESIS || depth > 1)
    {
        if(lexstate.lookahead.token == TK_OPEN_PARENTHESIS) //allow function calls inside as well
            depth++;
        else if(lexstate.lookahead.token == TK_CLOSE_PARENTHESIS)
            depth--;

        next(&lexstate);
        t = lexstate.t;
        os << t;
        lookahead(&lexstate);
    }
    os << TK_CLOSE_PARENTHESIS;
    lookahead(&lexstate);
}

May require another change somewhere, but doesn't look like it atm. I don't really remember the original state of the file so I can't say for sure.

Hello fellas,

the code pasted below works perfectly with pretty much all functions beside the when function itself. I was wondering if someone can share the code or already have a solution for parsing the array in the when function. 

Here is the code which occurs the error mentioned on the topic.
 

			case ST_WHEN_WITH_OR_BEGIN:
				{
					assert(nested==2);
					current_when_condition = "";
					if (t.token == TK_WITH)
					{
						// here comes Á¶°Ç½Ä
						next(&lexstate);
						ostringstream os;
						os << (lexstate.t);
						//cout << (lexstate.t);
						next(&lexstate);
						while (lexstate.t.token!=TK_DO)
						{
							os << " " <<(lexstate.t);
							//cout << TK_DO<<lexstate.t.token << " " <<(lexstate.t) <<endl;
							next(&lexstate);
						}
						current_when_condition = os.str();
						check_syntax("if "+current_when_condition+" then end", current_state_name+current_when_condition);
						cout << "\twith ";
						cout << current_when_condition;
						cout << endl;
						t = lexstate.t;
					}
					if (t.token == TK_DO)
					{
						ps = ST_WHEN_BODY;
						nested++;
					}
					else
					{
						//error("when doesn't have begin-end clause.");
						ostringstream os;
						os << "when doesn't have begin-end clause. (" << t << ")";
						error(os.str().c_str());
					}

				}
				break;

The switch case always return the else condition, does anyone have the missing parser code ?
