pline

pline is the catch-all function that outputs text to the message area. Depending on the GUI used and how many messages there already are in the message area, NetHack may wait for player to press a key at a --more-- prompt before showing the message.

pline accepts a string constant and any number of additional values that replace placeholders marked with '%' in the string constant, just like printf does.

Example:

int count;
for (count = 1; count < 10; count++) {
  pline("%i", count);
}
pline("Hello, player!");

void
pline VA_DECL(const char *, line)
#endif	/* USE_STDARG | USE_VARARG */

	putstr(WIN_MESSAGE, 0, line);
}

Norep

Norep() is similar to pline(), but if the same message is repeated after another, it's not shown again.

Example:

int x;
for (x = 0; x < 100; x++) {
  Norep("Whee!");
}

/*VARARGS1*/
void
Norep VA_DECL(const char *, line)
	VA_START(line);
	VA_INIT(line, const char *);
	no_repeat = TRUE;
	vpline(line, VA_ARGS);
	no_repeat = FALSE;

		you_buf = (char *) alloc((unsigned) you_buf_siz);
	}

}

void
free_youbuf()
{
	if (you_buf) free((genericptr_t) you_buf),  you_buf = (char *)0;
	you_buf_siz = 0;
}

/* `prefix' must be a string literal, not a pointer */

Strcpy((pointer = You_buf((int)(strlen(text) + sizeof prefix))), prefix)

#define YouMessage(pointer,prefix,text) \
strcat((YouPrefix(pointer, prefix, text), pointer), text)

You

You() is similar to pline(), but the string is prefixed with "You "

Example:

You("succeed in opening the tin.");

/*VARARGS1*/
void
You VA_DECL(const char *, line)
	char *tmp;
	VA_START(line);
	VA_INIT(line, const char *);
	vpline(YouMessage(tmp, "You ", line), VA_ARGS);
	VA_END();
}

Your

Your() is similar to pline(), but the string is prefixed with "Your "

Example:

Your("wallet is empty.");

/*VARARGS1*/
void
Your VA_DECL(const char *,line)
	char *tmp;
	VA_START(line);
	VA_INIT(line, const char *);
	vpline(YouMessage(tmp, "Your ", line), VA_ARGS);
	VA_END();
}

You_feel

You_feel() is similar to pline(), but the string is prefixed with "You feel "

Example:

You_feel("much better!");

/*VARARGS1*/
void
You_feel VA_DECL(const char *,line)
	char *tmp;
	VA_START(line);
	VA_INIT(line, const char *);
	vpline(YouMessage(tmp, "You feel ", line), VA_ARGS);
	VA_END();
}

You_cant

You_cant() is similar to pline(), but the string is prefixed with "You can't "

Example:

You_cant("wear that!");

/*VARARGS1*/
void
You_cant VA_DECL(const char *,line)
	char *tmp;
	VA_START(line);
	VA_INIT(line, const char *);
	vpline(YouMessage(tmp, "You can't ", line), VA_ARGS);
	VA_END();
}

pline_The

pline_The() is similar to pline(), but the string is prefixed with "The "

Example:

pline_The("door resists!");

/*VARARGS1*/
void
pline_The VA_DECL(const char *,line)
	char *tmp;
	VA_START(line);
	VA_INIT(line, const char *);
	vpline(YouMessage(tmp, "The ", line), VA_ARGS);
	VA_END();
}

There

There() is similar to pline(), but the string is prefixed with "There "

Example:

There("are no seats in here!");

/*VARARGS1*/
void
There VA_DECL(const char *,line)
	char *tmp;
	VA_START(line);
	VA_INIT(line, const char *);
	vpline(YouMessage(tmp, "There ", line), VA_ARGS);
	VA_END();
}

You_hear

You_hear() is similar to pline(), but the string is prefixed with different things depeneding whether the hero is under water, asleep or awake.

Example:

You_hear("crashing rock.");

/*VARARGS1*/
void
You_hear VA_DECL(const char *,line)
	char *tmp;
	VA_START(line);
	VA_INIT(line, const char *);
	if (Underwater)
		YouPrefix(tmp, "You barely hear ", line);
	else if (u.usleep)
		YouPrefix(tmp, "You dream that you hear ", line);
	else
		YouPrefix(tmp, "You hear ", line);
	vpline(strcat(tmp, line), VA_ARGS);
	VA_END();
}

verbalize

verbalize() is similar to pline(), but the string is prefixed and suffixed with double quotes, making it seem as if something said it. If hero cannot hear, this outputs nothing.

Example:

verbalize("You freed me!");

/*VARARGS1*/
void
verbalize VA_DECL(const char *,line)
	char *tmp;
	if (!flags.soundok) return;
	VA_START(line);
	VA_INIT(line, const char *);
	tmp = You_buf((int)strlen(line) + sizeof "\"\"");
	Strcpy(tmp, "\"");
	Strcat(tmp, line);
	Strcat(tmp, "\"");
	vpline(tmp, VA_ARGS);
	VA_END();
}

raw_printf

raw_printf() is only used if the GUI isn't yet initialized, but we still need to tell the player something important. For example, config file errors are output with this. Accepts the same kind of variable parameters as pline().

/*VARARGS1*/
/* Note that these declarations rely on knowledge of the internals
* of the variable argument handling stuff in "tradstdc.h"
*/

#if defined(USE_STDARG) || defined(USE_VARARGS)
static void FDECL(vraw_printf,(const char *,va_list));

void
raw_printf VA_DECL(const char *, line)
	VA_START(line);
	VA_INIT(line, char *);
	vraw_printf(line, VA_ARGS);
	VA_END();
}

# ifdef USE_STDARG
static void
vraw_printf(const char *line, va_list the_args) {
# else
static void
vraw_printf(line, the_args) const char *line; va_list the_args; {
# endif

#else  /* USE_STDARG | USE_VARARG */

void
raw_printf VA_DECL(const char *, line)
#endif
/* Do NOT use VA_START and VA_END in here... see above */

	if(!index(line, '%'))
	    raw_print(line);
	else {
	    char pbuf[BUFSZ];
	    Vsprintf(pbuf,line,VA_ARGS);
	    raw_print(pbuf);
	}
}

impossible

impossible() is used to tell the player that NetHack thinks something is wrong. This might or might not be bad enough that NetHack will crash. It accepts the same parameters as pline().

/*VARARGS1*/
void
impossible VA_DECL(const char *, s)
	VA_START(s);
	VA_INIT(s, const char *);
	if (program_state.in_impossible)
		panic("impossible called impossible");
	program_state.in_impossible = 1;
	{
	    char pbuf[BUFSZ];
	    Vsprintf(pbuf,s,VA_ARGS);
	    paniclog("impossible", pbuf);
	}
	vpline(s,VA_ARGS);
	pline("Program in disorder - perhaps you'd better #quit.");
	program_state.in_impossible = 0;
	VA_END();
}

align_str

align_str() takes one parameter, an alignment, and returns a string describing it.

const char *
align_str(alignment)
aligntyp alignment;
{
switch ((int)alignment) {
	case A_CHAOTIC: return "chaotic";
	case A_NEUTRAL: return "neutral";
	case A_LAWFUL:	return "lawful";
	case A_NONE:	return "unaligned";
}
return "unknown";
}

mstatusline

mstatusline() takes one parameter, a monster, and shows the player a short status of that monster. This is used when probing a monster.

void
mstatusline(mtmp)
register struct monst *mtmp;
{
	aligntyp alignment;
	char info[BUFSZ], monnambuf[BUFSZ];

	if (mtmp->ispriest || mtmp->data == &mons[PM_ALIGNED_PRIEST]
				|| mtmp->data == &mons[PM_ANGEL])
		alignment = EPRI(mtmp)->shralign;
	else
		alignment = mtmp->data->maligntyp;
	alignment = (alignment > 0) ? A_LAWFUL :
		(alignment < 0) ? A_CHAOTIC :
		A_NEUTRAL;

	info[0] = 0;

#endif

	/* avoid "Status of the invisible newt ..., invisible" */

ustatusline() shows the player the hero's status as if he was probed.

void

self_invis_message

self_invis_message() shows the player a message about the hero's invisibility; this should only be called if the hero just turned invisible.
