(shortopts): New constant. -DIGIT now always takes an optional arg.
(main): Revamp parsing of -DIGIT to let parse_tab_stops handle it.
Don't complain about -DIGIT.

place of nearly-equivalent code.

specified via the obsolete form. E.g., now this command fails:
_POSIX2_VERSION=1 ./expand -$(echo '2^64+1'|bc)
Before it would act like `_POSIX2_VERSION=1 ./expand -1'.

(usage): -i does not convert tabs after non-tabs.
(add_tab_stop): Renamed from add_tabstop. All uses changed.
(parse_tab_stop): Renamed from parse_tabstop. All uses changed.
(validate_tab_stop): Renamed from validate_tabstop. All uses changed.
(next_file, main): Check fclose against 0, not EOF.
(expand): Remove unnecessary casts.
Add another loop nesting level, for lines, so that per-line variables
are initialized cleanly.
Revamp tab checking. Check for write error immediately, rather
than just once at the end of the program.

next_file, expand, main):
Use bool for booleans.
(tab_size, tab_list, add_tabstop, parse_tabstops, validate_tabstops,
expand, main):
Use uintmax_t for column counts.
(add_tabstop): Don't reserve -1 (now UINTMAX_MAX) as a special value.
All callers changed.
(parse_tabstops): Don't pass a negative char to isblank.
Avoid memory leak with large tab stops.
(validate_tabstops, expand): Don't assume number of tab stops is
<= INT_MAX.
(next_file, main): Use EXIT_SUCCESS/EXIT_FAILURE rather than 0/1 when
storing values into exit_status.
(expand): Use same pattern as unexpand for reading chars.
Report an error when input line is too long, instead of silently
screwing up. Do not mishandle tab stops when backspacing left
over start of line.
|
|
(usage): Don't bother normalizing exit status
since the arg is already the correct exit status now.
|
|
(add_tabstop): Use x2nrealloc rather than xrealloc.
|
|
of 2003-09-19. Now, AUTHORS is a comma-separated list of strings.
Update the call to parse_long_options so that `AUTHORS, NULL' are the
last parameters.
* src/true.c (main): Append NULL to version_etc argument list.
* src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
|
|
Begin each WRITTEN_BY string with `Written by ' and end it with `.'.
Mark each WRITTEN_BY string as translatable.
|
|
|
|
Don't include closeout.h.

xrealloc, and xcalloc return values and of xrealloc's first argument.
|
|
`exit (1)' to `exit (EXIT_FAILURE)', and
`usage (1)' to `usage (EXIT_FAILURE)'.
|
|
|
|
(usage): Document only the intersection of the old and new behaviors,
to encourage portability.
(shortopts): Remove; no longer needed.
(main): Revert to previous behavior, except report
an error and exit if the obsolete syntax is used and if conforming
to the new standard.
|
|
support of obsolete "-N" option syntax in expand, head, fold,
split, tail, unexpand, uniq, and which prohibits options with
optional arguments in od and pr.
(shortopts): New constant.
(main): Check for obsolete options.
|
|
HELP_OPTION_DESCRIPTION and VERSION_OPTION_DESCRIPTION.
|
|
instead of hard-coding --help and --version descriptions.
|
|
Split usage strings so that --help and --version descriptions are alone
in their own string.
Likewise for the one that says:
Mandatory arguments to long options are mandatory for short options too.
|
|
Use fputs, not printf.
|
|
``Mandatory arguments to long options are mandatory for short options too.\n\''
|
|

[long_options]: Remove the "help" and "version" entries.
Remove declarations of show_help and show_version.
(main): Use parse_long_options, including author name(s).
Remove the show_version and show_help blocks.
