3ca688d69a Don't include "xalloc.h", as system.h already does that via sys2.h. 2002-01-21 19:53:23 +00:00
Jim Meyering
2fae9e5d26 Use new macros, HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION 
instead of hard-coding --help and --version descriptions.
Split --help output into smaller pieces.
Use fputs, not printf.

9e1b4e382a (usage): Indent --help and --version strings to start in the 7th column. 2001-11-25 14:46:05 +00:00
Jim Meyering
1463ff6353 (nextarg): Use strcoll, not strcmp. 2001-08-26 05:40:46 +00:00
Jim Meyering
4bc8b66e3a (posixly_correct): Remove; no longer needed. 
(main): Do not worry about POSIXLY_CORRECT, as it's OK for
expr to have options (so long as they do not begin with digits).
 2001-08-24 07:56:46 +00:00
Jim Meyering
9ee54a9b3a (nextarg): Advance ARGS by one if the next token matches. 
All callers changed.

2169593a4f (isstring): Remove. 
(eval2): Do comparisons as strings first, before trying to convert to
integer.  This avoids loss of information and wrong result, e.g. for
"expr '00' '<' '0!'", where you don't want to convert '00' to '0'.

2dce4a36d9 Code cleanup to avoid tricky macros and old-style function declarations. 
(cmpf, less_than, less_equal, equal, not_equal, greater_equal,
greater_than, arithf, arithdivf, plus, minus, multiply, divide, mod):
Remove.

(eval4, eval3, eval2): Rewrite to avoid the need for the above macros
and functions.

c6c2071280 Modify 'expr' so that it uses intmax_t, not int, to calculate 
the value of integer expressions.

(struct valinfo.i): Now intmax_t, not int.
(docolon, int_value, str_value, isstring, nextarg, toarith,
freev, tostring, trace): Remove unnecessary forward decls.
(int_value, printv, tostring, toarith, arithf, arithdivf, docolon,
eval6, eval4, eval3): Do integer arithmetic using intmax_t, not int.
(docolon): Don't assume size_t fits in int.
 2001-08-18 16:04:16 +00:00

From Karl Heuer.

8406b91aba (docolon): Test (re_buffer.re_nsub > 0) rather than 
searching for `\(' to determine whether to return 0 or the empty
string.  Before it would improperly return '' if the pattern
contained a substring like this: `\\('.  From Karl Heuer.
For example, running expr c : '\\(' should print `0'.

Jim Meyering
3d2a9041f9 (docolon): Don't use deceptively-named RE_SYNTAX_POSIX_BASIC -- it recognizes 
non-BRE \?, \+, and \|.  Instead, use RE_SYNTAX_POSIX_MINIMAL_BASIC.
 1996-03-02 02:45:20 +00:00
Jim Meyering
9a181424ac (eval6): Cast strlen to int to avoid warning from gcc -Wall. 1996-02-29 02:53:37 +00:00
Jim Meyering

Jim Meyering
85f9983c19 (docolon): Set re_syntax_options to RE_SYNTAX_POSIX_BASIC
