What's New in V6.12

New Features in Make v6.12 [Top]

The following features have been added to the lastest version of Opus Make. For details of these added features and of other changes made to Make v6.12, please see the Addendum for v6.12.

• The new "SH" (execute shell) macro modifier executes the shell line defined by a macro and returns the output of the shell line. This is equivalent to using "%exec" on a shell line with the output redirected into a file, then the "@" macro modifier to read the file contents. The "SH" modifier is better in that it handles the redirection, file handling, and "@" modifier for you.

• The new ".OPTIONS : QueueUnlimit" removes the 32-file limit from the shell-line queuing, enabling an arbitrary number of targets to be queued.

• For Win95 and WinNT, better support of mixed-case file names. See the ".OPTIONS : TargetKeepCase" keyword.

• For Win95 new ".SHELL : .NOOPUSERRH" lets Make better support 4DOS.

• The .SEARCH directive is now a complete superset of the .PATH.ext macros.

• In inline response files, "\!" can now be used to protect an initial "!" character.

• Support for Microsoft NMAKE 1.62 (as shipped with MS VC++ 5.0).

• Better detection of read-time indenting.

• Better handling of leading/trailing whitespace around continued makefile lines during PM/CB & NMAKE emulation.

• To differentiate between a drive-letter colon and a dependency colon, Make required a ":", ";", "<space>" or "<nothing>" after the colon. This requirement has been relaxed and now these characters are needed only when the thing before the colon is a single letter. For example:

	D:foo

is parsed as the single target "D:foo", but:

	all:CLEAN

is parsed as "all depends on CLEAN".

Bugs Fixed in Make v6.12 [Top]

• The ^Z on the end of some MS-DOS makefiles was not properly handled.

• On "%set name<op>value" lines, <op> was not properly detected at "=", "+=" or ":=".

• Mixing read-time "%set" and "=" macro definitions did not work well. "%set" macro definitions could not be redefined with an "=" macro definition.

• The following:

	NAME = $$
	%set NAME += $$
	%echo NAME=$(NAME)

would evaluate to "NAME=$$ $" rather than "NAME=$ $".

• For Win95 Make, "make -x any_file" caused a SHARE error.

• In automatic response files, "/<any> <any>" is now kept together in the response file. This is for MSVC++, where "/D" or "/I" on one line followed by the argument on the next line fails in the MSVC++ command-line parser.

• "\t" inside a regular expression set would not match tab. Instead it would match a literal "t".

• A target defined in MAKE.INI, then showing up as:

	<target> :

in the makefile would be reset, its shell lines forgotten. Now, only rules are reset when they appear in this fashion (eg. ".c.obj :").

• For NMAKE emulation, additional extensions given in the .SUFFIXES directive are added to the end of .SUFFIXES.

• For NMAKE emulation, comment-only lines following a continued line are ignored without stopping the continued state. That is:

	A = one \
	# an ignored line
	two

evaluates to:

	A = one two

• For NMAKE emulation, environment variables modified in the makefile with a macro definition were not expanding out the right side of the macro definition. For example:

	INC = xyzzy
	INCLUDE = $(INCLUDE);$(INC)
	x :
		echo %%INCLUDE%%

would echo "<old value of INCLUDE>;$(INC)" instead of "<old value of INCLUDE>;xyzzy".

• For NMAKE emulation, "cd dir" is translated to a "%cd dir" directive. However, this failed with a compound statement "cd dir & cmd". Now, Opus Make detects the compound statement and passes it to the shell (as per NMAKE).

New Features in MKMF v6.12 [Top]

• For Win95 and WinNT, better support of mixed-case file names. See the ".OPTIONS : TargetKeepCase" keyword.

• MKMF’s startup emulation can now be set, either with command-line switches –EN, –EO and –EP or with the SETEM utility.

• The "%exec" directive now works.

• The new "SH" macro modifier executes a shell line and captures the text output into the macro.

Bugs Fixed in MKMF v6.12 [Top]

• MKMF did not understand numbers that ended in "U" or "L".

• MKMF did not trap divide-by-zero or modulus-by-zero errors when interpreting directives.

• Changing the .TYPE.C regex to something that did not start with "#" did not work.

• With parameterized paths, ".." relative paths did not work.

• #defined macros were limited to 4K bytes. This limit has been doubled to 8K bytes.
