|
|
|
57 |
correct conversion of number to string based on various flags
|
|
|
58 |
and the value of vp->fmt. The idea is to not convert again
|
|
|
59 |
if xFMT is the same as before and we're doing the same conversion.
|
|
|
60 |
Otherwise, clear the old flags, set the new, and reconvert.
|
|
|
61 |

With scalpel, tweasers, magnifying glass and bated breath,
|
|
|
79 |
borrow code from the NetBSD version of nawk to fix the years-old
|
|
|
80 |
bug whereby decrementing the value of NF did not change the
|
|
|
81 |
record.
|
|
|
82 |
|
|
|
83 |
* lib.c (fldbld): Set donerec to 1 when done.

|
|
|
87 |
* tran.c (setfree): New function.
|
|
|
88 |
* tran.c (setfval): Normalize negative zero to positive zero.
|
|
|
89 |
If setting NF, clear donerec and call setlastfld().
|
|
|
90 |
(setsval): Remove call to save_old_OFS(). If setting OFS, call
|
|
|
91 |
recbld(). If setting NF, clear donerec and call setlastfld().
|
|
|
92 |
|
|
|
93 |
As part of the process, revert OFS-related changes of 2018-05-22:
|
|
|
94 |
|
|
|
95 |
* awk.h (saveOFS, saveOFSlen, save_old_OFS): Remove declarations.
|
|
|
96 |
* lib.c (recbld): Use *OFS instead of saveOFS.
|
|
|
97 |
* run.c (saveOFS, saveOFSlen, save_old_OFS): Remove.

|
|
