From: Mike Brennan <brennan@boeing.com> Subject: v02i028: mawk - (Ver. 1.1) An interpreter for the AWK language, Patch02a/4 Newsgroups: comp.sources.reviewed Approved: csr@calvin.dgbt.doc.ca Submitted-by: Mike Brennan <brennan@boeing.com> Posting-number: Volume 2, Issue 28 Archive-name: mawk/patch02a Patch-To: mawk: Volume 1, Issue 50-68 This is patch2 for mawk1.1 which updates mawk1.1.1 to mawk1.1.2 The changes fix all bugs reported since 1.1.1, and add new configurations for aix, convex and sysVr4i386.

Evidently I lack the requisite mental facilities ! to understand posix comparisons , i.e. ! ! echo 0 | mawk '$0 == "0000" { print "true" }' ! true ! ! was a major bozo. ! ! 2) If n = split(s, X, r) , then all elements other than ! X[1..n] are now deleted from X. This behavior is ! consistent with other awks. ! ! 3) foo = "foo" ! foo++ evaluates to 0 and value of foo is 1 ! ! old behavior was foo++ was "foo" and foo then set to 1 ! ! 4) Fixed two bugs in regular expression lexical scanner: ! ! [c1-c2] did not work right if c2 was an escaped character. ! ! function do_str() which collected runs of characters did ! not work right if the last character was escaped and the run ! ended with * + or ?. ! ! 5) You can now read and write to the same file. E.g. ! ! printf "Enter: " > "/dev/tty" ! getline answer < "/dev/tty" ! ! 6) Output to files which are ttys is now unbuffered. ! ! 7) FILENAME and FNR retain their value from the last record in ! the END section. ! ! 8) man pages might groff. ! ! 9) New configuration files ! aix.h convex.h sysVr4i386.h ! ! 10) Better error recovery for bungled function definitions ! via new productions ! ! program_block : outside_error block ; ! error : outside_error ; ! ! 11) If i > NF , then ++$i , $i++, g?sub(r,s,$i), now work ! correctly. ! ! 12) MsDOS, interactive input: terminating a line with ^Z ! works correctly (at least with TC++ compiler). ! ! l3) string_buff had too many users which induced an error in ! sprintf(). After parsing, string_buff is now only be used ! by sprintf(). !
