And since neither i do have a running 9atom nor are there 9atom

Re: [9fans] 9atom installation fails due to missing files [solved]
Yapadapad! While biking i became enlightened. Just disabled the network and it boots (VirtualBox 4.2.16, OS X). It seems the system hangs around trying to get some IP address via DHCP?? I don't know why it does so long (minutes) and requires such a lot of CPU time (though of the VM) doing so, ... but it's working just fine! Just some more years 'till i know what i'm talking about!! --steffen
[9fans] 9atom installation fails due to missing files
Hello,
today i finally made it to one of the things i was looking forward
to, installing 9atom. It was a truly smooth experience. (Some
`cannot set [gu]id on xy' messages, mostly for a `bootes' user in
/usr and /cron, and also for secstore{,/store,/who}.)
But then, unfortunately, there were quite some copy errors which
caused the installation to fail.
/n/[newfs - dist]/68020/lib/{ape,libc.a}
/n/[newfs - dist]/alpha/lib/{ape,libc.a}
/n/newfs/sys/src/pcpae/{archacpi,audioac97{,m},audiohd}.c
(because /n/newfs/sys/src/pcpae doesn't exist)
Oh, what a shame! Is there anything i can do about that? (The
9atom.iso has been downloaded on 2013-06-25.) Any help on Monday
would bee appreciated!
P.S.: Does the Plan9/9atom awk(1) has the same bug that i ran into
this week? It is present in all awk(1)s i've tested, including
GNU awk(1) ($TAWK is simply awk, and UnicodeData.txt is 6.2.0):
## Input producers
io_unicode_data() {
unicode/UnicodeData.txt ${TAWK} '
BEGIN {FS = ; ; OFS = ;}
# There are no comments in this, but..
/^[[:space:]]*[^#]+$/ {
i = $2
# Ranges must become unrolled, otherwise step on
if (i !~ /, First/) {
$2 =
print
next
}
r1 = sprintf(%d, 0x $1)
getline
r2 = sprintf(%d, 0x $1)
$2 =
# Note: this gets around bugs in all tested awk(1)s: the range
# F-D, and only that one, will *not* be evaluated unless we to
# force integerfication
r1 = r1 + 0
r2 = r2 + 0
while (r1 = r2) {
$1 = sprintf(%X, r1)
printf %s\n, $0
++r1
}
}
'
}
Thanks and ciao!

[9fans] Character case mappings
'Thing is; i'm writing a Unicode aware library for ISO C99 aware
environments (*earliest* alpha state) and at the moment i use
binary searches (i only have display-widths and simple case
mappings right now). For combined upper/lower case mappings i do
end up with
static struct _casemap {
uint32_t start; /* First code point */
uint32_t accu : 16; /* Relative distance to mapping */
_Bool isneg: 1; /* Accu must be subtracted */
_Bool isup : 1; /* Code point is uppercase */
_Bool islull : 1; /* Is Lu/Ll range (.accu = range start 1) */
_Bool isemap : 1; /* Has a one-to-many mapping */
uint32_t count : 12; /* Number of entries in this range */
} const _casemaps[] = {
{0x41,32, 0,1,0,0, 26},
...
{0x010428,40, 1,0,0,0, 40},
}; /* 250 entries */
that can be accessed via
static struct _casemap const *
_find_casemap(uint32_t codep)
{
struct _casemap const *cme = _casemaps, *dp;
uint32_t min = 0, max = ARRAYCOUNT(_casemaps) - 1;
if (codep = cme[min].start codep cme[max].start + cme[max].count)
do {
uint32_t mid = (min + max) 1,
s = (dp = cme + mid)-start;
if (codep s)
max = --mid;
else if (codep = s + dp-count)
min = ++mid;
else {
cme += mid;
goto jleave;
}
} while (max = min);
cme = NULL;
jleave:
return cme;
}
uint32_t
sud_simple_tolower(uint32_t codep)
{
struct _casemap const *cme = _find_casemap(codep);
if (cme == NULL)
;
else if (! cme-islull) {
if (cme-isup)
codep = cme-isneg ? codep - cme-accu : codep + cme-accu;
} else if ((codep 1) == cme-accu)
++codep;
return codep;
}
uint32_t
sud_simple_toupper(uint32_t codep)
{
struct _casemap const *cme = _find_casemap(codep);
if (cme == NULL)
;
else if (! cme-islull) {

codep = cme-isneg ? codep - cme-accu : codep + cme-accu;
} else if ((codep 1) != cme-accu)
--codep;
return codep;
}
My S-CText (on sourceforge DOT net SLASH p SLASH s-ctext SLASH
code SLASH) tests all 0x10 code points correct with the
above. Now when i look at the sys/src/libc/port/runetype.c (of
plan9front) then i think this one is generated, but i cannot find
the creating script or program, which would be of interest to me.
And maybe Plan9 would be interested to see the above patched into
that, at some later time. ?
Thank you and ciao,

[9fans] 9front Acme unresponsive to key presses

I also installed 9front in the meanwhile (python, pfff), and learned that the (broken) hostname setup can be skipped during installation, and how easy it is to set the german keyboard layout! That is really great (and it would be so easy to adjust it as necessary!) design! Acme in 9front doesn't respond to keypresses and starts hanging around; i'd have a (rather useless though) 13997 bytes screenshot of what happens on the controlling tty during this, in case noone else has seen this and the behaviour is of interest -- it's just that you place the cursor, hold down a key, and nothing visual happens, but at times something comes back and then it seems as if something has been queued somewhere, but not necessarily the key that has been pressed (in fact the screenshot shows bad character in filename, which *definitely* not happened). But maybe it's VM related anyway, which might be true since i had to turn to VESA which is not needed for Plan9 from Bell Lapps, which also doesn't show the mentioned behaviour. |khm --steffen
