| | | | | | | | | | | 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 Wollman2002-10-282-32/+34
| | | | | | | | | | | 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

* EXPR_COMPAT should imply -e, since there is no way to specify it otherwise,Garrett Wollman2002-05-112-1/+18
| | | | | | | 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 Wollman2002-05-102-46/+88
| | | | | | | | | 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

* Make expr POSIX-compliant, and fix some bugs. Specifically:Garrett Wollman2002-03-222-104/+215
| | | | | | | | | | | | | | | | - 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
