* Make the long-awaited change from $Id$ to $FreeBSD$Jordan K. Hubbard1997-01-141-1/+1
| | | | | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise. Notes: svn path=/head/; revision=21673
* Fix my own brokeness for the colon operator, when one of the argumentsJoerg Wunsch1995-11-181-33/+31
| | | | | | | | was a valid integer. The actual decision between integer and string is now context-dependant on the operator being used. Notes: svn path=/head/; revision=12378
* expr(1) didn't comply to Posix.2 and its own man page: anyJoerg Wunsch1995-08-041-1/+13
| | | | | | | | | | | comparisions have been made as string comparisions, even in cases where both operands clearly qualified as integers. The fix is to make the parser properly analyzing whether an operand is a valid integer or not. Notes: svn path=/head/; revision=9909
* You will find enclosed some changes to make gcc -Wall more happy inJoerg Wunsch1995-03-191-2/+3
| | | | | | | | | | | | /usr/src/bin. Note that some patches are still needed in that directory. I (Joerg) finished most of Philippe's cleanup. /bin/sh will still need *allot* of work, however. Submitted by: charnier@lirmm.fr (Philippe Charnier) Notes: svn path=/head/; revision=7165

* Explicitly include <sys/types.h> before including <regex.h>. This isBruce Evans1994-09-051-0/+1
| | | | | | | | apparently required by POSIX. It will be required in practice when the bogus inclusion of <sys/types.h> is removed from <stdio.h>. Notes: svn path=/head/; revision=2502
* Allow expressions like "expr 'ABC' : '^.*$' to work as is done in otherJ.T. Conklin1993-10-041-9/+3
| | | | | | | expr implementations. Notes: svn path=/head/; revision=539
* Fix grammar to eliminate support for unary minus expressions -- theyJ.T. Conklin1993-09-141-9/+8
| | | | | | | | weren't supported, they aren't standard, and they caused expr to dump core. Notes: svn path=/head/; revision=468
* 1003.2 requires that lexical comparisons be done in locale specific manner,J.T. Conklin1993-08-171-34/+29
| | | | | | | | | | so we have to use strcoll() instead of strcmp(). 1003.2 requires that a null string be returned if a string does not match a \( \) subexpression. Replaced fprintf/exit with calls to err and errx as appropriate. Notes: svn path=/head/; revision=295
* Update to my latest expr (fixes bugs with comparison and matching operators)J.T. Conklin1993-07-211-42/+7
