"""A script to prepare version informtion for use the gtest Info.plist file.
|
|
|
|
This script extracts the version information from the configure.ac file and
|
|
uses it to generate a header file containing the same information. The
|
|
#defines in this header file will be included in during the generation of
|
|
the Info.plist of the framework, giving the correct value to the version
|
|
shown in the Finder.
|
|
|
|
This script makes the following assumptions (these are faults of the script,
|
|
not problems with the Autoconf):
|
|
1. The AC_INIT macro will be contained within the first 1024 characters
|
|
of configure.ac
|
|
2. The version string will be 3 integers separated by periods and will be
|
|
surrounded by squre brackets, "[" and "]" (e.g. [1.0.1]). The first
|
|
segment represents the major version, the second represents the minor
|
|
version and the third represents the fix version.
|
|
3. No ")" character exists between the opening "(" and closing ")" of
|
|
AC_INIT, including in comments and character strings.
