* mdoc(7) police:ru2002-11-261-1/+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

* Create a small library function, check_utility_compat(3), to determinewollman2002-10-281-31/+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.

* EXPR_COMPAT should imply -e, since there is no way to specify it otherwise,wollman2002-05-111-1/+17
| | | | and -e reflects the historic behavior of FreeBSD's expr.
* The response to my POSIX interpretation request says that `expr'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.
* Provide an environment variabloe, EXPR_COMPAT, which disables optionwollman2002-04-221-2/+16

* Fix a few formatting brainos and make the formatting of the EXAMPLESwollman2002-03-221-6/+9
| | | | section somewhat clearer.
* Make expr POSIX-compliant, and fix some bugs. Specifically: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.

| | | | | | | | 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.
