Pre-Announcement for R.S.N.
5.9.8
- portability bug fixes
- Mac OS/X and very old guile problems
- option deprecation
- By specifying the option attribute, deprecated,
there will be two effects: the usage text will not
show the option, and the generated documentation will mark it with:
NOTE: THIS OPTION IS DEPRECATED
- command line disablement
- Sometimes, options just should not be specifiable on the command line.
So, you may now specify that the command line may not load or save options
and options you specify may also be prohibited from the command line. disable-load and disable-save will disable loading
and saving option state on the command line, and the no-command attribute will prevent your option from being
recognized on the command line. They are also omitted from the usage text.
Announcement for December 2008
5.9.7
-Werror causes problems
- ...especially on Cygwin. So, "configure" has been modified so that
it gets inserted on compilations only if export WERROR=yes
has been set for configure time.
- flags-must and flags-cant
- When option names are used as C variables, hyphens must be replaced
with underscores. This wasn't being done for these option conflict
tests.
- usage.tpl compilations
- This template is used to produce usage text at build time,
instead of the "normal" run time. Relative path names in -I
options were not working correctly.
- --more-help and getopt.tpl
- ``--more-help'' is supported within libopts. Thus, if you are avoiding
using libopts by using the getopt.tpl template, there will be no
support for it. You must specify, no-libopts; in your option
definitions. This will remove any mention of ``--more-help'' in any
generated documentation or usage text.
- --used-defines option to AutoGen
- This will cause the autogen program to print out each definition name
it tried to look up, whether found or not. I have found it useful for ensuring that all option definition file attributes get defined.
Announcement for November 2008
5.9.6
- Saving options (configurations) to a file
- Support has now been added to save hierarchically valued options (options with "suboptions").
(See also Automatically Supported Options.)
This is very useful for automated editing of daemon process config files.
Instead of using an editor and changing it directly, the optionProcess
function validates the new state before writing it out. At that point,
the "configuration file editor" program can signal the daemon to reload its
configuration.
- new option: reset-option
- This option will take as its
argument the name of another option. The state of that option will be
completely cleared, as if it had never been specified. This is the only
way to remove a configured value, if you wish to rewrite the config file.
- New option argument type: time
- The argument is a string representing a duration of time.
Internally, your program will see the time_t value in seconds.
The conversion will be done by the soon-to-be-released GNU lib
function, "parse_duration()". I have also added the SCM function time-string->number
