* Remove BUGS section that talked about missing multibyte character support.Tim J. Robbins2004-07-121-5/+1
| | | | | | | We have support now that the regular expression routines do. Notes: svn path=/head/; revision=132029

* mdoc(7) police:Ruslan Ermilov2002-11-261-1/+1
| | | | | | | | | | | Revert to using the .Tn POSIX and .Tn ANSI instead of \*[Px] and \*[Ai] strings; using these strings is unsafe in troff mode, as they include a change in a font size. Approved by: re Notes: svn path=/head/; revision=107282

* Create a small library function, check_utility_compat(3), to determineGarrett Wollman2002-10-281-31/+32
| | | | | | | | | | | whether a named utility should behave in FreeBSD 4.x-compatible mode or in a standard mode (default standard). The configuration is done malloc(3)-style, with either an environment variable or a symlink. Update expr(1) to use this new interface. Notes: svn path=/head/; revision=106065
* mdoc(7) police: markup nits.Ruslan Ermilov2002-05-291-11/+11
| | | | Notes: svn path=/head/; revision=97464
* EXPR_COMPAT should imply -e, since there is no way to specify it otherwise,Garrett Wollman2002-05-111-1/+17
| | | | | | | and -e reflects the historic behavior of FreeBSD's expr. Notes: svn path=/head/; revision=96382
* The response to my POSIX interpretation request says that `expr'Garrett Wollman2002-05-101-16/+23
| | | | | | | | | is required to be oblivious to overflow and to use the data type `long'. (Division by zero is undefined in ISO C so it's still OK to check for it here.) Add a new `-e' flag to get the old, more useful behavior. Notes: svn path=/head/; revision=96367
* Provide an environment variabloe, EXPR_COMPAT, which disables optionGarrett Wollman2002-04-221-2/+16

* Add a word of caution about integer arithmetic range and overflow detection.Garrett Wollman2002-03-221-0/+6
| | | | Notes: svn path=/head/; revision=92983
* Fix a few formatting brainos and make the formatting of the EXAMPLESGarrett Wollman2002-03-221-6/+9
| | | | | | | section somewhat clearer. Notes: svn path=/head/; revision=92982
* Make expr POSIX-compliant, and fix some bugs. Specifically:Garrett Wollman2002-03-221-16/+97
| | | | | | | | | | | | | | | | - expr must conform to the Utility Syntax Guidelines, so use getopt() to eat the (non-existent) options. - Use the Standard type intmax_t for arithmetic. - If an argument cannot be *completely* converted to an integer, then it is a string. Additionally make some style cleanups near the modified lines. This utility is still not completely style-compliant. Notes: svn path=/head/; revision=92979

* 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
