This file lists all bug fixes, changes, etc., made since the
second edition of the AWK book was published in September 2023.
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.
