This file lists all bug fixes, changes, etc., made since the
second edition of the AWK book was published in September 2023.
Nov 24, 2023:
Fix issue #199: gototab improvements to dynamically resize the
table, qsort and bsearch to improve the lookup speed as the
table gets larger for multibyte input. thanks to Arnold Robbins.
Nov 23, 2023:
Fix Issue #169, related to escape sequences in strings.
Thanks to Github user rajeevvp.
Fix Issue #147, reported by Github user drawkula, and fixed
by Miguel Pineiro Jr.
Nov 20, 2023:
rewrite of fnematch to fix a number of issues, including
extraneous output, out-of-bounds access, number of bytes
to push back after a failed match etc.
thanks to Miguel Pineiro Jr.
Nov 15, 2023:
Man page edit, regression test fixes. thanks to Arnold Robbins
consolidation of sub and gsub into dosub, removing duplicate
code. thanks to Miguel Pineiro Jr.
gcc replaced with cc everywhere.
Oct 30, 2023:
multiple fixes and a minor code cleanup.
disabled utf-8 for non-multibyte locales, such as C or POSIX.
fixed a bad char * cast that causes incorrect results on big-endian
systems. also fixed an out-of-bounds read for empty CCL.
fixed a buffer overflow in substr with utf-8 strings.
many thanks to Todd C Miller.
Sep 24, 2023:
fnematch and getrune have been overhauled to solve issues around
unicode FS and RS. also fixed gsub null match issue with unicode.
big thanks to Arnold Robbins.
Sep 12, 2023:
Fixed a length error in u8_byte2char that set RSTART to
incorrect (cannot happen) value for EOL match(str, /$/).
-----------------------------------------------------------------
[This entry is a summary, not a precise list of changes.]
Added --csv option to enable processing of comma-separated
values inputs. When --csv is enabled, fields are separated
by commas, fields may be quoted with " double quotes, fields
may contain embedded newlines.
If no explicit separator argument is provided, split() uses
the setting of --csv to determine how fields are split.
Strings may now contain UTF-8 code points (not necessarily
characters). Functions that operate on characters, like
length, substr, index, match, etc., use UTF-8, so the length
of a string of 3 emojis is 3, not 12 as it would be if bytes
were counted.
Regular expressions are processes as UTF-8.
Unicode literals can be written as \u followed by one
to eight hexadecimal digits. These may appear in strings and
regular expressions.
