dnl AS_VERSION

dnl example

dnl AS_VERSION

dnl this macro

dnl - AC_SUBST's PACKAGE_VERSION_MAJOR, _MINOR, _MICRO

dnl - AC_SUBST's PACKAGE_VERSION_RELEASE,

dnl    which can be used for rpm release fields

dnl - doesn't call AM_INIT_AUTOMAKE anymore because it prevents

dnl   maintainer mode from running correctly

dnl

dnl don't forget to put #undef PACKAGE_VERSION_RELEASE in acconfig.h

dnl if you use acconfig.h

AC_DEFUN([AS_VERSION],

[

  PACKAGE_VERSION_MAJOR=$(echo AC_PACKAGE_VERSION | cut -d'.' -f1)

  PACKAGE_VERSION_MINOR=$(echo AC_PACKAGE_VERSION | cut -d'.' -f2)

  PACKAGE_VERSION_MICRO=$(echo AC_PACKAGE_VERSION | cut -d'.' -f3)

  AC_SUBST(PACKAGE_VERSION_MAJOR)

  AC_SUBST(PACKAGE_VERSION_MINOR)

  AC_SUBST(PACKAGE_VERSION_MICRO)

])

dnl AS_NANO(ACTION-IF-NANO-NON-NULL, [ACTION-IF-NANO-NULL])

dnl requires AC_INIT to be called before

dnl For projects using a fourth or nano number in your versioning to indicate

dnl development or prerelease snapshots, this macro allows the build to be

dnl set up differently accordingly.

dnl this macro:

dnl - parses AC_PACKAGE_VERSION, set by AC_INIT, and extracts the nano number

dnl - sets the variable PACKAGE_VERSION_NANO

dnl - sets the variable PACKAGE_VERSION_RELEASE, which can be used

dnl   for rpm release fields

dnl - executes ACTION-IF-NANO-NON-NULL or ACTION-IF-NANO-NULL

dnl example:

dnl AS_NANO(RELEASE="yes", RELEASE="no")

AC_DEFUN([AS_NANO],

[

  AC_MSG_CHECKING(nano version)

  NANO=$(echo AC_PACKAGE_VERSION | cut -d'.' -f4)

  if test x"$NANO" = x || test "x$NANO" = "x0" ; then

    AC_MSG_RESULT([0 (release)])

    NANO=0

    PACKAGE_VERSION_RELEASE=1

    ifelse([$1], , :, [$1])

  else

    AC_MSG_RESULT($NANO)

    PACKAGE_VERSION_RELEASE=0.`date +%Y%m%d.%H%M%S`

    if test "x$NANO" != "x1" ; then

       ifelse([$1], , :, [$1])

    else

       ifelse([$2], , :, [$2])

  PACKAGE_VERSION_NANO=$NANO

  AC_SUBST(PACKAGE_VERSION_NANO)
