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. Such a mechanism is pretty much compulsory for embedded applications.

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.

here strings

When the here string terminating marker cannot be found, the referenced line number would be the last one in the file. Fixed.

configury

A number of data types were accommodated in the compat/compat.h header file, but not actually used anywhere. These have been removed so they do not have to be properly configured any more either.

Web site changes

Some have complained that rebuilding autogen from pure CVS source required a tool not available to the rest of the world. True enough. Autogen character classifications are more elaborate than those used in the ctype.h header. The most common example being, ``Is this character allowed to be in a variable name?'' Alphanumeric is close, but leaves out the underscore. So, I am publishing the char-mapper program. It converts a character classification table into a collection of macros to use inside autogen.

5.9.5

CygWin

CygWin has some implementations of funopen and fopencookie that vary from the normal versions. Adapted some configury code to distinguish.

AutoOpts generated headers

It turned out to be highly useful to emit the "export" code before the option enumeration. Specifically, that code might include some defines that alter which options get activated.

Described what "noag-boot.sh" was all about.

5.9.4

arg-type = file

AutoOpts now supports file names as an argument type. You may specify whether file must pre-exist, or must not pre-exist. You may also elect to have it pre-opened with either fopen(3C) or open(2).

scaling suffix for integer option arguments

integer option arguments may now be marked as ``scaled''.
