[9fans] awk

[Kenji Arisawa]

I tested some awk string functions to examine if
they can handle UFT-8 code well.
The bollow is my text code:
#!/bin/rc
#
#	Can awk function handle UTF strings ?
#
echo 'ベル:研究所' | awk '{
print $0	# ベル:研究所
print length($0)	# 6
print index($0,":")	# 3
print match($0,":.*"),RSTART, RLENGTH	# 7	7 4
print substr($0,3)	# :研究所
a=$0; sub(":.+", "alice", a); print a	# ベルalice
}'

Output is commented after `#' in each line.
Function `match' returns byte position that is inconsitent
with others. I believe this is a bug.

It seems this bug is fixed in recent update.

I'm not insulting you, but...

As is seen here recently, we seem to have small developpersnow.
Furthermore, this is an example of an application bug, and it's
deeply related to consistency of usage of UTF-8 in an application.
Taking into consideration of these facts, I think you'd better to report
the fix for it, because I believe you can do it.   I'm supposing this seems
not to be a serious bug, probably just in a match function etc.. No I have
no idea for this though.

just my two cents,

Kenji

On linuces, you'll go back once you start using gawk-3.1.0. It has very
highly abstracted Plan-9zy syntactical model for socket programming. Once
gawk incorporates a multithreading model, I won't have to make any more
excuses for not wanting to know Perl.

Not that I care about ksh, you may leave it and concentrate on other, more important things,
so as to make 'it' on time.

However, I am _really_ interested in just what it is that oyu want to get done in time.
Especially since there has been mentionings before of a new Plan9 version...

I still don 't have the full plan9 - just the pcdist.

The precompiled binary should work - if you have the right
to make it available.

Thanks

to answer vladimir's question, the plan 9 port of awk
is useless without plan 9: you need plan 9 both to build
it and to run it, so there is no reason to release other
than as part of the system.

the version of awk that we ship is always ported from
brian's most recent version in his home directory and
is therefore in sync with what brian is currently releasing.

we are trying to port the new ksh, but it is a total
mess so i don't know if we'll get it done in time,
but we are trying.

Conversely, if I recall correctly, the verison that shipped with the
second edition wasn't the most recent.  Ditto for ksh.

Fixed in Brazil?

Yes it is.

But, what about the Plan9 port of it?

Due to the licence - have anyone the right to make it
available in public?

Thank you
Vladimir.
