Acme tag for when editing man pages

I've been writing more man pages recently that aren't in the usual Manpath and instead of building a new plumbing rule I made a tag

% cat /acme/bin/Man
#!/bin/rc

if(~ $#* 0) {
tags=`{cat /mnt/acme/$winid/tag}
f = $tags(1)
}
if not
f = $1

nroff -man $f


cd with cd - feature

On Lunix cd as an extra feature namely cd -
which takes you to the previous directory

I've got quite into this as I jump about, freebsd had pushcd and popcd which was also fun.

fn cd {
cdnextlastdir = `{pwd}
{
if(~ $#* 0)
builtin cd
if not if(~ $1 -)
builtin cd $cdlastdir
if not
builtin cd $1
} && cdlastdir = $cdnextlastdir
}

I've got it in lib/profile

EXAMPLE


t23% cd
t23% pwd
/usr/maht
t23% cd /
t23% pwd
/
t23% cd -
t23% pwd
/usr/maht
t23% cd ouihouihiuh
Can't cd ouihouihiuh: 'ouihouihiuh' file does not exist
t23% cd -
t23% pwd
/
t23% cd -
t23% pwd
/usr/maht
t23%


4th-compiler error reporting

Compiling; Word 444: Undefined name

is a bogus error message. The only way to match that word number is to compile the code !!
So I edited the compiler :

4th-3.5d3-unix/sources/comp_4th.c:/^Object->ErrNo = M4NONAME;/
s/$/printf("WORD %s", p);/


so it spits out the duff word
Compiling; Word 444: Undefined name
WORD dup4

which I suppose is ok for a start but I can do better than that but let's not get sidetracked

as an aside, programming in Lunix code is like going back in time. I mean FILE* !! gimme a break.

4th-compiler word list

comp_4th.c & exec_4th.c
is where the action happens

4th-compiler opening plan9 devices

This didn't work, no surprise.
Refill introduces an integer.
and USE nuked the stack, so I'm investigating that

First is dial
With minimal comments. I stripped my notes out to see how terse it is without them.

With comments

Dial looks ready to test tomorrow so lets hope this post doesn;t last long.
