GNU 系统开发优化 C 语言程序的应用程序

	specially: If this brace succedes a struct-like thing and it goes
	on a line by itself (! btype_2), then add `brace_indent' to the
	amount of indentation.  This make GNU-style indentation of
	structures, etc. work properly.

	* indent.c (indent): In case rparen, if not the beginning of the
	code, and in_decl, set `parser_state_tos->want_blank'.  This is to
	handle ensure a space before the last rparen of cases like
	"int (*fp ()) ()".

Fri Jul 24 18:53:15 1992  Joseph Arceneaux  ([e-mail])

	* indent.c: Changes to handle spaces between options and their
	values.  It would be better to use `getopt', but this change is
	much simpler.
	Declaration of `set_option' changed to return int.
	(main): Increment `i' by the value of `set_option ()'; also, pass
	argv[i + 1] as second parameter to `set_option'.
	* args.c (set_option): Take new parameter `param'.
	New label `arg_missing', just before label `found', to handle
	missing option value error.
	If `param_start' is 0, set it to `param'.
	(scan_profile): Rewritten to look at two entries at once, and pass
	both to `set_option'.

Wed Jul 22 15:55:56 1992  Joseph Arceneaux  ([e-mail])

	* indent.c (indent): In case lbrace, set
	`parser_state_tos->want_blank' under certain conditions if not at
	beginning of line and `btype_2' was specified.

	* indent.c: Macro `need_chars' moved here from indent.h.

	* io.c (read_file, read_stdin): No longer appends " \n" to the end
	of the file, which is now simply delimited with '\0'.  xmalloc 2
	less bytes for the buffer.
	(fill_buffer): Stop and set `had_eof' when '\0' is
	encountered in the file text, then return immediately.
	* lexi.c (lexi): New case in main switch statement for '\0', which
	indicates eof.  Removed code to set this in case '\n'.

Fri Jul 10 14:45:25 1992  Joseph Arceneaux  ([e-mail])

	* lexi.c (): If keyword "struct" was found inside of parens
	(case rw_struct_like:) set parser_state_tos->cast_mask before
	breaking.

	* lexi.c (lexi): Accept 'U' and "UL" suffixes on integer
	constants.

	to decl_indent (dec_indent) if we are inside parens
	(parser_state_tos->paren_depth > 0).

Thu Jul  2 13:36:50 1992  Joseph Arceneaux  ([e-mail])

	* indent.c (indent): In case rparen, if paren starts the line,
	check that paren_level is greater than zero before using it to
	index `paren_indents'.

	* args.c: New variable `leave_preproc_space'.  Set by new option
	"-lps".
	* indent.h: Declare `leave_preproc_space'.
	* indent.c (indent): In case preesc, don't ignore blanks after '#'
	if `leave_preproc_space' is set.
	* indent.texinfo: Entries added for new option "-lps".

	* indent.c: At the end of case preesc, call dump_line() if this
	appears to be a case where it won't get called when processing the
	newline character.

Wed Jul  1 16:12:57 1992  Joseph Arceneaux  ([e-mail])

	* lexi.c (hash, is_reserved): Regenerated (from gperf) with new
	words "volatile" and "const".

	* args.c: Removed the trailing comma from the last element of enum

	* Version 1.4 released.

Fri Jun 12 15:02:37 1992  Joseph Arceneaux  ([e-mail])

	* globs.c (mymemcpy): Now a void function.  Don't return anything.

	* io.c (dump_line): When printing label, use `tabsize' to
	increment target if `com_st' contains tabs.  Also use
	`tabsize' to calculate target when it's less than zero.

Thu Jun 11 20:27:48 1992  Joseph Arceneaux  ([e-mail])

	* indent.c (indent): When token_type is a binary_op, if
	parser_state_tos->want_blank is not true, but the preceding
	character is not a space, put one on the line.

	* Removed variable `sccsid' from all files.

Wed Jun 10 13:00:26 1992  Joseph Arceneaux  ([e-mail])

	* args.c: Added long option name "dont-space-special-semicolon"

	* globs.c: `mymemcpy ()' only defined #ifndef mymemcpy.

	* indent.c (main): Set `in_name' to the current input file name.

	* io.c (dumpline): Check parser_state_tos->paren_level before
	using it to index parser_state_tos->paren_indents.

Mon Jun  8 17:55:07 1992  Joseph Arceneaux  ([e-mail])

	* lexi.c (lexi): In conditional (paren_count == 0), add '=' to the
	characters (along with ';', ',', and '(') which constitute a
	function definition.  This was to cause an ugly declaration from
	libc ("int (*foo) __P ((int bar)) = bax;") to remain on one line.
	Note that this is not valid C.

	* indent.c (main): When indenting multiple output files, make sure
	to close each output file before continuing.

Fri Jun  5 13:56:54 1992  Joseph Arceneaux  ([e-mail])

	* io.c (read_file): Use mymemcpy() instead of bcopy();

	BERKELEY_DEFAULTS is defined, default `continuation_indent' to 4.

Sun May  3 00:43:10 1992  Joseph Arceneaux  (jla at hugo)

	* parse.c (reduce):  when reducing <stmt><dolit>,
	do set i_l_follow to il[parser_state_tos].  This was removed
	earlier after a new reduction was added, but this obviously fixes
	some bugs.  It will stay if indent passes all the old tests.

	* args.c (set_option):  When calling `addkey' to add a user
	identifier, make it type 'rw_decl' since these are supposed to be
	typedef identifiers.
	Removed "-d4" spec in "-orig" option settings.
	Made default for "-fca" be false.

	* args.c (set_profile): Only read one profile.  The one in the
	current directory has priority.  Return the path of the profile read.
	* indent.c (main): If `verbose' and we've read a profile, tell the
	user on the stderr.

Sat May  2 18:33:14 1992  Joseph Arceneaux  (jla at hugo)

	* args.c: `Bill_Shannon' replaced with `blank_after_sizeof'.
	indent.c: Likewise.
	indent.h: Likewise.

	* args.c: New variable, exp_nip, for new option "-nip", which is
	equivalent to "-ip0".  Long option name is
	"no-parameter-indentation".

	include file with directory reading definitions.
	* Makefile:  Take "config.sh" and "dirent_def.h" into account.

	* backup.c: Make only simple backups if we can't read directories
	(NODIR is defined).  Functions for numbered backups conditionally
	defined.
	Documented all functions.

	* indent_globs.h:  Broken into two new files, indent.h and sys.h.
	All files changed accordingly, including the Makefile.

Thu Apr 30 14:53:33 1992  Joseph Arceneaux  (jla at hugo)

	* backup.c, backup.h: New files with backup routines.
	* io.c (make_backup): Moved into backup.c.
	* io.c (sys_error): No longer static, called from make_backup.

Wed Apr 29 14:56:10 1992  Joseph Arceneaux  (jla at hugo)

	* args.c: Make default value for `else_endif_col' 1, as in "-gnu"
	settings.

Tue Apr 28 23:18:07 1992  Joseph Arceneaux  (jla at hugo)

	output file is specified, or one input stream is used and -st is
	specified.

Sun Mar 22 14:59:35 1992  Joseph Arceneaux  (jla at hugo)

	* parse.c (init_parser, reset_parser):  Two new functions which
	respectively allocate the neccessary parser data structures, and
	initialize the parser state.
	* indent.c (indent): New function which does the actual indenting
	of it's input, which comes in the form of a file_buffer pointer.
	(main): Command line scan changed to use new option "-o" and read
	possibly multiple files into new variable `in_file_names'.
	Main body changed to use new `indent' function on possibly
	multiple files, and accomodate default standard io specification.

	* io.c (make_backup, read_file, read_stdin):  All file io routines
	rewritten (`make_backup' formerly `bakcopy').  read routines
	return pointer to new structure 'file_buffer'.
	`make_backup' only makes backup file, no longer sets up original
	file for writing.
	* indent_globs.h:  Declare struct file_buffer, and io routines.

Fri Mar 20 18:33:18 1992  Joseph Arceneaux  (jla at hugo)

	* args.c: Option "-st" and associated variable `use_stdinout'
	removed.  Option "-o" and associated variable `expect_output_file'

	* Makefile: info version of manual included in distribution.

	* args.c: New long options "berkeley-style", "berkeley" added
	which correspond to original style.

	* lexi.c ():  Added explicit parens in checks for alphanums.
	* indent.c (main):  On switch default when searching brace, added
	explicit parens to 2nd if statment.
	* indent_globs.h, io.c: Made variable `in_prog_size' unsigned.
		 
Wed Jan 15 11:59:35 1992  Joseph Arceneaux  (jla at hugo)

	* args.c:  Accept "-gnu" option.

	* indent.c (main): In case rbrace, don't use ind_level and il[tos]
	as criteria for setting search_brace.  This allows "-ce" to work
	more strictly.

	* indent.c (main): In case lparen, let '(' after an ident which is
	rw_return begin casts.
	* lexi.c (lexi): If ident was a reserved word, save it in
	parser_state_tos->last_rw.
	Changed "return" from `rw_break' to new enum element `rw_return'.
	* indent_globs.h: Moved type "enum codes" to this file from
	lexi.c.  New element of parser state `last_rw'.

Sun Jan 12 01:40:23 1992  Joseph Arceneaux  (jla at hugo)

	* lexi.c (lexi): if in decl and looking at '(', additionally
	accept, after closing ')',  '(' as constituting a function
	declaration (along with ';' and ',').

	* io.c (dump_line):  When outputting nonblank lines, if
	n_real_blanklines is > 1 and swallow_optional_blanklines is set,
	make n_real_blanklines 1.

Wed Jan  8 10:06:43 1992  Joseph Arceneaux  (jla at hugo)

	* args.c (option_prefix):  New function to recognize option prefix
	from table.  Now handles both "+" and "--" for long option prefixes.

Mon Jan  6 01:15:29 1992  Joseph Arceneaux  (jla at hugo)

	* Makefile:  Made more compatible with GNU standards.  Unix man
	file removed from distribution.

Fri Dec 27 14:58:13 1991  Joseph Arceneaux  (jla at hugo)

	* parse.c:  Correctly handle "do ... while" statements, using new
	stack symbol DOSTMT.
	(parse):  For semicolon, if code DOSTMT is top of stack, replace it
	with STMT.
	(reduce):  New reduction <dohead><whilestmt> => <dostmt>.  Also,
	when reducing <stmt><dolit>, don't change indentation.

	* indent.c (main):  In case rbrace, after parse(rbrace), set
	force_nl if top of stack is dohead and ! btype_2.
	(main):  Initialize noncast_mask to 0.

Mon Dec 23 18:34:11 1991  Joseph Arceneaux  (jla at hugo)

	* args.c (set_option): Recognize long options, using new struct
	option_conversions, if option begins with POSIX_OPTION_PREFIX.

	* indent.c (main): Recognize "--no-profile" as well as "-npro".

	* indent.texinfo: Describe GNU style as default.  Section reworded.

Sat Dec 21 13:27:07 1991  Joseph Arceneaux  (jla at hugo)

	* indent.c (main):  In case preesc (~ line 1282), add !had_eof to
	second while clause to avoid hanging in weird text (like test file
	djm-torture-test/t11).

	* indent.c (main): In case rparen, (~ line 680) if cast mask was
	set and is reset to zero, then set parser_state_tos->want_blank if
	cast_space was set.  No longer do this (#if 0) in all cases where
	(!parser_state_tos->cast_mask || cast_space).

Wed Dec  4 16:41:13 1991  Joseph Arceneaux  (jla at hugo)

	* version.h:  Version changed to be simply 1.1.4.  Comments added.

Mon Nov 25 15:16:51 1991  Joseph Arceneaux  (jla at hugo)

	* indent.c (main):  When handling decl case, don't reset
	PREFIX_BLANKLINE_REQUESTED if we've just encountered the type of a
	procedure delcaration.  This fixes the -bap bug for procedures
	which begin with a line declaring their type, following the line with
	`}' from the last procedure.

Fri Nov 22 15:26:59 1991  Joseph Arceneaux  (jla at hugo)

	* args.c: Default is now GNU style.  Original obtained by new

	* args.c: Removed the "-ss" option for GNU style.

Fri Sep 13 01:30:18 1991  Joseph Arceneaux  (jla at hugo)

	* indent_globs.c: New element to parser_state, `paren_depth',
	which counts global paren nesting.
	* indent.c: Use it in main loop to avoid setting `in_or_st' when
	doing ansii prototyping.

Thu Sep 12 15:53:54 1991  Joseph Arceneaux  (jla at hugo)

	* io.c (dump_line): Initialize target_column to 0.

	* parse.c: New variable debug to control debugging output.
