Pre-Announcement for R.S.N.

5.18.5pre4

Please note that this is a prerelease. It is not stable. Bugs are likely to be found. Nevertheless, I'd like to know if there are issues, so please let me know of any problems you have.

man pages on Solaris
AutoGen uses in memory streams to handle temporary output redirections. Solaris and a few other systems have no such beast. The templates for man pages presumed that the system it was running on used them. Fixed.

optioning version mismatch message
The wrong stringification C preprocessing macro was used. The string now gets constructed correctly without a stringify macro.

Announcement for August, 2014

5.18.4

dne - Do Not Edit
This Scheme function has "traditionally" included a date and time stamp in the resulting output and that could be suppressed by providing it a "-d" option. Due to very reasonable complaints, the new default is to not include the date and require a "-D" option to enable dates. However, even that is not completely satisfactory. The user of the template needs a way to select behavior. Enter the newly recognized environment variable: AUTOGEN_DNE_DATE If set, it will override any "-D" option in the template. If set to the empty string or a string with the first character being one of 0nNfF (zero or the first letter of "false" or "no"), then the date will not be emitted. Otherwise, the presence of this environment variable will cause the date to be emitted.

RETURN macro
This is a relatively new function that allows you to leave a DEFINEd macro from anywhere within it. Well, almost. Since FOR loops insert definition contexts, these must be properly unwound, and they were not. It works now.

optionPrintVersionAndReturn()
This is a new option library function. This will allow you to write a version handling function that prints additional information after the standard information. Such a function should likely pay attention to any argument to the option. Please read the source for the print_ver function for specifics.

mdoc and man pages
A number of noticable improvements incorporated from the NTP project. (Thank you, Harlan Stenn et al.)

libopts tear-off library
The library needs stdnoreturn.h, so the infrastructure for testing presence and hacking together a substitute are now included in the tear-off tarball.

yylex() for definitions
The definition scanner now accepts hexadecimal numbers prefixed with "0x" without requiring quotes around the value.

tracing improvement
When nested autogen runs are dumping their trace output to the same file, finding the start and end of the nested run is a little obscure. The trace output now prefixes the first and last lines with === making it easier to spot and correlate.

fixed the m4 macro AG_COMPILE_FORMAT_ARG
The code assumed the main function had an "argc" argument.

Announcement for May, 2014

5.18.3

Guile issues
The auto-edit of Guile headers depends upon configured values. Most especially it depends upon the configuration of the token noreturn, and ptrdiff_t. Otherwise, Guile will do strange and different things, depending on its minor version.

aborting
Abort from the failing function so that stack traces are useful

make sure library option handling code does nothing when the library is just trying to get information about an option.

perl program options
A new template perlopt.tpl has been added. It utilizes the Getopt::Long perl package. It allows perl programs to have generated man pages and texi docs.

i18n and help text
The aoGetsText() emitted i18n helper function needs its argument to have the "format_arg" attribute. A wrapper macro ATTRIBUTE_FORMAT_ARG has been added for this purpose. It is set during configure via the AG_COMPILE_FORMAT_ARG m4 macro.
