I was poking around at the TODO and I saw this:
* make configure print out a summary when it's done (like XEmacs)
I'm working on a patch to bring in this functionality, out of sheer
"I need to learn more about autoconf and I want to contribute to
PHP"- ness :). Does anyone have any thoughts on what might go into
such a summary? So far, I have install prefix, SAPI, debug on/off,
things of that simple nature. Also, any thoughts on whether the
summary should be printed from configure itself or config.status?
I would say it should list every option that the user can select, and
show its value. For extra credit, on each entry tell if the value is
the default - either set to the default value, or not specified.
The general consensus seems to be that I should show as much info as is
reasonably possible. For this, extensions need to be able to register
the summary information they can provide. I've come up with a couple of
different ideas for the syntax on this:
1) Add a new parameter to PHP_NEW_EXTENSION(), i.e.:
PHP_NEW_EXTENSION(standard, array.c base64.c basic_functions.c
browscap.c crc32.c # \ etc,
,,,, \
[Standard functions
Regex type:--with-regex=${REGEX_TYPE}])
2) AC_DEFUN() a new macro, i.e.:
PHP_SUMMARY_INFO([Standard functions], [Extension: Enabled
Regex type: --with-regex=${REGEX_TYPE}])
These are just random examples based on the standard extension,
obviously. Anyone like either of these or have a better idea?
I really don't think it is worth changing/adding to the extension API
for this in any way.
If we can't do a simple summary with what we already have, let's just
skip it. And as far as I am concerned, showing as much as possible
isn't the goal here. The goal for me would be to get a summary that
fits on a single 80x25 page without scrolling. If it is so long that it
scrolls off, then we haven't gained much. It should be a quick-summary
that you can glance at and quickly pick out if everything looks ok.
