- Rename _package_alternative_inner() to _find_package_alternative() and
modify it to make it more useful when called from other functions. If
a package is found that matches one of the alternatives, its name is
printed on stdout, otherwise nothing is printed (empty output).
- Adapt _package_alternative() accordingly and rename it
to _mandatory_pkg_alternative().
- New function _optional_pkg_alternative() based on
_find_package_alternative(). Contrary to _mandatory_pkg_alternative(),
if no match is found in _optional_pkg_alternative(), a message is
printed to stdout but the script doesn't abort.
By setting the 'ident' attribute for /download_and_compile.sh, this
replacement will be automatic whenever the file is checked out.
Note: the ID is the 40-character hexadecimal blob object name in Git, it
is *not* the commit ID. 'git show <id>' can be used to obtain the
script contents from its blob object name (id).
This will avoid spoiling every diff with the version number change, or
alternatively having different versions of the same file displaying and
logging the same version number.
If download_and_compile.sh is moved to a different directory in FGMeta
(or even renamed), then the path in .gitattributes must be adapted for
the substitution to work (the '/' in .gitattributes anchors the match at
the containing directory; I did this because download_and_compile.sh is
a rather generic name, and there *might* be different scripts with the
same name in other dirs...).
- Add function _package_alternative() to select between alternative
packages (idea of Pat Callahan).
- Split the 'apt-get update' and 'apt-get install' steps to arrange for
installation of the 'dctrl-tools' prerequisite of
_package_alternative().
- Add and use functions _aptUpdate() and _aptInstall() for good
factoring (makes testing easier for people not using sudo, allows one
to easily switch from 'apt-get' to 'apt' or 'aptitude' if wanted,
etc.).
