Typestr was one of the things to come out of Ken's parting
flurry of activity. Here's the complete documentation as we have
it from his show-and-tell a couple of days before he left:

#include	<u.h>
#include	<libc.h>

typestr	struct	_cmplx	Cmplx;
struct	_cmplx
{
	double	r;
	double	i;
};
int	Zconv(va_list*, Fconv*);

#pragma	varargck	type	"Z"	Cmplx

void
main(void)
{
	Cmplx a, b;
	int ia[10];
	double d;

	fmtinstall('Z', Zconv);
	a = (Cmplx){1, 0};
	b = (Cmplx){0, 1};

	a = -((a + b) - (b - a)) + -((a - b) - (b + a));
	print("a = %Z\n", a);
	a += b;
	print("a = %Z\n", a);

	if(a == a)
		print("ok\n");

	a = (d = a);
	print("d = %g\n", d);
	print("a = %Z\n", a);

	a = (Cmplx)1.0;
	print("a = %Z\n", a);
}

/*
 * print conversion
 */
int
Zconv(va_list *arg, Fconv *fp)
{
	char s[50];
	Cmplx z;

	z = va_arg(*arg, Cmplx);
	sprint(s, "(%g %g)", z.r, z.i);
	strconv(s, fp);
	return sizeof(z);
}

/*
 * operators
 */
Cmplx
_cmplx_pos_(Cmplx a)
{
	Cmplx r;

	r.r = +a.r;
	r.i = +a.i;
	return r;
}

Cmplx
_cmplx_neg_(Cmplx a)
{
	Cmplx r;

	r.r = -a.r;
	r.i = -a.i;
	return r;
}

Cmplx
_cmplx_add_(Cmplx a, Cmplx b)
{
	Cmplx r;

	r.r = a.r + b.r;
	r.i = a.i + b.i;
	return r;
}

Cmplx
_cmplx_sub_(Cmplx a, Cmplx b)
{
	Cmplx r;

	r.r = a.r - b.r;
	r.i = a.i - b.i;
	return r;
}

int
_cmplx_eq_(Cmplx a, Cmplx b)
{
	Cmplx r;

	return a.r == b.r && a.i == b.i;
}

/*
 * assignment-op (can be made from assig and op)
 */
Cmplx
_cmplx_asadd_(Cmplx *a, Cmplx b)
{
	*a = *a + b;
	return *a;
}

Cmplx
_cmplx_assub_(Cmplx *a, Cmplx b)
{
	*a = *a - b;
	return *a;
}

/*
 * conversions
 */
int
_cmplx_i_(Cmplx a)
{
	return sqrt(a.r*a.r + a.i*a.i);
}

double
_cmplx_d_(Cmplx a)
{
	return sqrt(a.r*a.r + a.i*a.i);
}

Cmplx
_d_cmplx_(double a)
{
	Cmplx r;

	r.r = a;
	r.i = 0;
	return r;
}

Ken is more active than he has been in a long time,
he's just not at Lucent anymore.

But what does it do?  I just spent a few minutes looking
at the compiler source, and it was not obvious to me.

Re: [9fans] Compilation error??

[Russ Cox]

you can't use typestr anymore.  it's a reserved word.

[9fans] Compilation error??

[Ish Rattan]

Hello,

The 3/27 upgrade broke the alef port from 2nd to 3rd edition. An invocation
of 8c (3/27 version) generates the following errors. Lines 85 to 95 in the
header file are shown below too. Replacing char *typestr[] by char **typestr
does not help.

Any ideas?
