This file lists all bug fixes, changes, etc., made since the AWK book
|
||||
was sent to the printers in August, 1987.
|
||||
|
||||
Nov 29, 2002:
|
||||
modified b.c (with tiny changes in main and run) to support
|
||||
locales, using strcoll and iswhatever tests for posix character
|
||||
classes. thanks to ruslan ermilov (ru@freebsd.org) for code.
|
||||
the function isblank doesn't seem to have propagated to any
|
||||
header file near me, so it's there explicitly. not properly
|
||||
tested on non-ascii character sets by me.
|
||||
|
||||
Jun 28, 2002:
|
||||
modified run/format() and tran/getsval() to do a slightly better
|
||||
job on using OFMT for output from print and CONVFMT for other
|
||||
number->string conversions, as promised by posix and done by
|
||||
gawk and mawk. there are still places where it doesn't work
|
||||
right if CONVFMT is changed; by then the STR attribute of the
|
||||
variable has been irrevocably set. thanks to arnold robbins for
|
||||
code and examples.
|
||||
|
||||
fixed subtle bug in format that could get core dump. thanks to
|
||||
Jaromir Dolecek <jdolecek@NetBSD.org> for finding and fixing.
|
||||
minor cleanup in run.c / format() at the same time.
|
||||
|
||||
added some tests for null pointers to debugging printf's, which
|
||||
were never intended for external consumption. thanks to dave
|
||||
kerns (dkerns@lucent.com) for pointing this out.
|
||||
|
||||
GNU compatibility: an empty regexp matches anything (thanks to
|
||||
dag-erling smorgrav, des@ofug.org). subject to reversion if
|
||||
this does more harm than good.
|
||||
|
||||
pervasive small changes to make things more const-correct, as
|
||||
reported by gcc's -Wwrite-strings. as it says in the gcc manual,
|
||||
this may be more nuisance than useful. provoked by a suggestion
|
||||
and code from arnaud desitter, arnaud@nimbus.geog.ox.ac.uk
|
||||
|
||||
minor documentation changes to note that this now compiles out
|
||||
of the box on Mac OS X.
