From 7e403195e574be5174815a51cf5c42f06f76a87a Mon Sep 17 00:00:00 2001 From: Stephan Bergmann Date: Sat, 30 Nov 2019 17:48:32 +0100 Subject: Introduce o3tl::optional as an alias for std::optional ...with a boost::optional fallback for Xcode < 10 (as std::optional is only available starting with Xcode 10 according to , and our baseline for iOS and macOS is still Xcode 9.3 according to README.md). And mechanically rewrite all code to use o3tl::optional instead of boost::optional. One immediate benefit is that disabling -Wmaybe-uninitialized for GCC as per fed7c3deb3f4ec81f78967c2d7f3c4554398cb9d "Slience bogus -Werror=maybe-uninitialized" should no longer be necessary (and whose check happened to no longer trigger for GCC 10 trunk, even though that compiler would still emit bogus -Wmaybe-uninitialized for uses of boost::optional under --enable-optimized, which made me ponder whether this switch from boost::optional to std::optional would be a useful thing to do; I keep that configure.ac check for now, though, and will only remove it in a follow up commit). Another longer-term benefit is that the code is now already in good shape for an eventual switch to std::optional (a switch we would have done anyway once we no longer need to support Xcode < 10). Only desktop/qa/desktop_lib/test_desktop_lib.cxx heavily uses boost::property_tree::ptree::get_child_optional returning boost::optional, so let it keep using boost::optional for now. After a number of preceding commits have paved the way for this change, this commit is completely mechanical, done with > git ls-files -z | grep -vz -e '^bin/find-unneeded-includes$' -e '^configure.ac$' -e '^desktop/qa/desktop_lib/test_desktop_lib.cxx$' -e '^dictionaries$' -e '^external/' -e '^helpcontent2$' -e '^include/IwyuFilter_include.yaml$' -e '^sc/IwyuFilter_sc.yaml$' -e '^solenv/gdb/boost/optional.py$' -e '^solenv/vs/LibreOffice.natvis$' -e '^translations$' -e '\.svg$' | xargs -0 sed -i -E -e 's|\|o3tl/optional.hxx|g' -e 's/\/o3tl\1::\2\3optional/g' -e 's/\/o3tl\1::\2nullopt/g' (before committing include/o3tl/optional.hxx, and relying on some GNU features). It excludes some files where mention of boost::optional et al should apparently not be changed (and the sub-repo directory stubs). It turned out that all uses of boost::none across the code base were in combination with boost::optional, so had all to be rewritten as o3tl::nullopt.
