2019-01-26 Arnold D. Robbins <arnold@skeeve.com> * main.c (version): Updated. 2019-01-25 Arnold D. Robbins <arnold@skeeve.com> * run.c (awkgetline): Check for numeric value in all getline variants. See the numeric-getline.* files in bugs-fixed directory. 2018-08-29 Arnold D. Robbins <arnold@skeeve.com> * REGRESS: Check for existence of a.out. If not there, run make. Enable core dumps for T.arnold system status test to work on MacOS X. 2018-08-22 Arnold D. Robbins <arnold@skeeve.com> * awktest.tar (testdir/T.expr): Fix test for unary plus. 2018-08-22 Arnold D. Robbins <arnold@skeeve.com> * REGRESS: Extract tests if necessary, set PATH to include '.'. * regdir/beebe.tar (Makefile): Fix longwrds test to prefix sort with LC_ALL=C. * awktest.tar: Updated from fixed test suite, directory it extracts is now called 'testdir' to match what's in top-level REGRESS script. * regdir: Removed, as Brian wants to keep the test suite in the tar file. 2018-08-22 Arnold D. Robbins <arnold@skeeve.com> * FIXES, lib.c, run.c, makefile, main.c: Merge from Brian's tree. * REGRESS: New file, from Brian. * awktest.tar: Restored from Brian's tree. 2018-08-22 Arnold D. Robbins <arnold@skeeve.com> * awkgram.y (UPLUS): New token. In the grammar, call op1() with it. * maketab.c (proc): Add entry for UPLUS. * run.c (arith): Handle UPLUS. * main.c (version): Updated. * bugs-fixed/unary-plus.awk, bugs-fixed/unary-plus.bad, bugs-fixed/unary-plus.ok: New files. 2018-08-10 Arnold D. Robbins <arnold@skeeve.com> * TODO: Updated. * awk.1: Improve use of macros, add some additional explanation in a few places, alphabetize list of variables. 2018-08-08 Arnold D. Robbins <arnold@skeeve.com> * awk.h (Cell): Add new field `fmt' to track xFMT value used for a string conversion. [CONVC, CONVO]: New flag macros. * bugs-fixed/README: Updated. * bugs-fixed/string-conv.awk, bugs-fixed/string-conv.bad, bugs-fixed/string-conv.ok: New files. * main.c (version): Updated. * proto.h (flags2str): Add declaration. * tran.c (setfval): Clear CONVC and CONVO flags and set vp->fmt to NULL. (setsval): Ditto. Add large comment and new code to manage correct conversion of number to string based on various flags and the value of vp->fmt. The idea is to not convert again if xFMT is the same as before and we're doing the same conversion. Otherwise, clear the old flags, set the new, and reconvert. (flags2str): New function. For debug prints and for use from a debugger. 2018-08-05 Arnold D. Robbins <arnold@skeeve.com> Fix filename conflicts in regdir where the only difference was in letter case. This caused problems on Windows systems. * regdir/Compare.T1: Renamed from regdir/Compare.T. * regdir/t.delete0: Renamed from regdir/t.delete. * regdir/t.getline1: Renamed from regdir/t.getline. * regdir/t.redir1: Renamed from regdir/t.redir. * regdir/t.split1: Renamed from regdir/t.split. * regdir/t.sub0: Renamed from regdir/t.sub. * regdir/REGRESS: Adjusted. 2018-08-04 Arnold D. Robbins <arnold@skeeve.com> With scalpel, tweasers, magnifying glass and bated breath, borrow code from the NetBSD version of nawk to fix the years-old bug whereby decrementing the value of NF did not change the record. * lib.c (fldbld): Set donerec to 1 when done. (setlastfld): New function. * proto.h (setlastfld): Add declaration. * run.c (copycell): Make code smarter about flags (from NetBSD code). * tran.c (setfree): New function. * tran.c (setfval): Normalize negative zero to positive zero. If setting NF, clear donerec and call setlastfld(). (setsval): Remove call to save_old_OFS(). If setting OFS, call recbld(). If setting NF, clear donerec and call setlastfld(). As part of the process, revert OFS-related changes of 2018-05-22: * awk.h (saveOFS, saveOFSlen, save_old_OFS): Remove declarations. * lib.c (recbld): Use *OFS instead of saveOFS. * run.c (saveOFS, saveOFSlen, save_old_OFS): Remove. * tran.c (syminit): Remove initialization of saveOFS and saveOFSlen. General stuff that goes along with all this: * bugs-fixed/README: Updated. * bugs-fixed/decr-NF.awk, bugs-fixed/decr-NF.bad, bugs-fixed/decr-NF.ok: New files. * main.c (version): Updated. * regdir/README.TESTS: Fix awk book title. * regdir/T.misc: Revise test to match fixed code. * run.c (format): Increase size of buffer used for %a test. (Unrelated to NF or OFS, but fixes a compiler complaint.) 2018-06-07 Arnold D. Robbins <arnold@skeeve.com> * regdir/beebe.tar: Fix longwrds.ok so that the test will pass. The file was incorrectly sorted. 2018-06-06 Arnold D. Robbins <arnold@skeeve.com> * regdir/T.lilly: Fix the bug again in the second instance of the code. Thanks to BWK for pointing this out. 2018-05-31 Arnold D. Robbins <arnold@skeeve.com> * regdir/T.lilly: Fix a syntax error and ordering bug in creating the 'foo' file. 2018-05-23 Arnold D. Robbins <arnold@skeeve.com> * awk.1: Remove standalone 'awk' at the top of file, it messed up the formatting. Arrange built-in variable list in alphabetical order. 2018-05-23 Arnold D. Robbins <arnold@skeeve.com> * main.c (version): Add my email address and a date so that users can tell this isn't straight BWK awk. * README.md: Minor updates. * TODO: Updated. 2018-05-22 Arnold D. Robbins <arnold@skeeve.com> Add POSIX-required formats %a and %A. * run.c (format): Check for %a support in C library. If there, allow %a and %A as valid formats. * TODO: Updated. * bugs-fixed/README: Updated. * bugs-fixed/a-format.awk, bugs-fixed/a-format.bad, bugs-fixed/a-format.ok: New files. 2018-05-22 Arnold D.

Robbins <arnold@skeeve.com> * TODO: New file. 2018-05-22 Arnold D. Robbins <arnold@skeeve.com> * makefile (gitadd, gitpush): Remove these targets. They should not be automated and were incorrect for things that would be done regularly. 2018-05-22 Arnold D. Robbins <arnold@skeeve.com> Fix nawk so that [[:blank:]] only matches space and tab instead of any whitespace character, originally made May 10, 2018. See bugs-fixed/space.awk. This appears to have been a thinko on Brian's part. * b.c (charclasses): Use xisblank() function for [[:blank:]]. * bugs-fixed/README: Updated. * bugs-fixed/space.awk, bugs-fixed/space.bad, bugs-fixed/space.ok: New files. 2018-05-22 Arnold D. Robbins <arnold@skeeve.com> * .gitignore: New file. 2018-05-22 Arnold D. Robbins <arnold@skeeve.com> Fix nawk to provide reasonable exit status for system(), a la gawk, originally made March 12, 2016. See bugs-fixed/system-status.awk. * run.c (bltin): For FSYSTEM, use the macros defined for wait(2) to produce a reasonable exit value, instead of doing a floating-point division by 256. * awk.1: Document the return status values. * bugs-fixed/README: Updated. * bugs-fixed/system-status.awk, bugs-fixed/system-status.bad, bugs-fixed/system-status.ok: New files. 2018-05-22 Arnold D. Robbins <arnold@skeeve.com> Bug fix with respect to rebuilding a record, originally made August 19, 2014.

(save_old_OFS): New function to save OFS aside. * tran.c (syminit): Initialize saveOFS and saveOFSlen.

Robbins <arnold@skeeve.com> * makefile (YACC): Use bison. 2018-05-22 Arnold D. Robbins <arnold@skeeve.com> * ChangeLog: Created. * regdir: Created.
