(main): Don't complain about -TAB.
|

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

(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.
(unexpand): 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.
(TAB_STOP_SENTINEL): Remove.
(tab_size): Now size_t, not uintmax_t, since we need to store
the sequences of blanks.
(max_column_width): New var.
(usage): Say "blank" where POSIX requires this.
(add_tab_stop): Calculate maximum column width.
(unexpand): Store the pending blanks, instead of merely counting them.
Follow POSIX's rules about -a requiring two blanks before a tab stop.
Get rid of internal label and goto.
|
|
Include quote.h, xstrndup.h.
(TAB_STOP_SENTINEL): Increase from INT_MAX to INTMAX_MAX.
(convert_entire_line, have_read_stdin, parse_tabstops, next_file,
unexpand, main):
Use bool for booleans.
(tab_size, tab_list, add_tabstop, validate_tabstops, unexpand):
Use uintmax_t for column counts.
(first_free_tab, validate_tabstops, unexpand): Use size_t for sizes.
(add_tabstop, parse_tabstops, main): Don't reserve UINTMAX_MAX
as a tab stop.
(parse_tabstops): Don't use ISBLANK on possibly-signed char.
Detect overflow in tab stop string.
(next_file, main): Use EXIT_FAILURE/EXIT_SUCCESS instead of 1/0.
(unexpand): Concatenate input files the same way expand does.
|
|
(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.
|
|
(-a).
|
|
`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): Parse options using POSIX 1003.1-2001 rules if
conforming to that standard. Do not warn of obsolete options.
|
|
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.
(usage): Document this.
(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\''
|
|
|
|
(anonymous enum) [CONVERT_FIRST_ONLY_OPTION]: Define.
(long_options): Add `first-only'.
(main): Handle new option.
|
|
(unexpand): Use it instead of INT_MAX.
Declare column and pending to be `unsigned'.
Increment pending and column counters only if column is smaller
than TAB_STOP_SENTINEL.
|
|
|
|
|
|
|
|
|
|
|
|
[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.

Remove definitions of those symbols.
* src/csplit.c: Move inclusion of regex.h/rx.h to follow system.h
since it now includes limit.h which defines RE_DUP_MAX.
* src/nl.c: Likewise.
* src/tac.c: Likewise.
|
|
(add_tabstop): Cast first arg of xrealloc to char*.
