Shorten compilation times Now fish shell stores version is a small file called by other files. This means that a slight change which modifies one file won't cause many of files to recompile. The compilation unit is intentionally small, this is by design. The smaller it is, the faster it will recompile, and it will be compiled a lot. 2014-05-01 15:46:27 +08:00			`#include "fish_version.h"`

Generate version numbers for Xcode builds Teach Xcode to run new script xcode_version_gen.sh before building the fish_shell and fish_indent targets. The script generates file fish-build-version.h for inclusion by fish_version.cpp. Note that Xcode always runs the script because of the phony target named force-fish-build-version.h, but fish-build-version.h is only touched if the contents of FISH-BUILD-VERSION-FILE change.

[cmake] Untangle the CMake versioning This untangles the CMake versioning issues (I hope) as discussed in #4626. Note most of the advice found on the Internet about how to inject git versions into CMake is just wrong. The behavior we want is to unconditionally run the script build_tools/git_version_gen.sh at build time (i.e. when you invoke ninja or make, and not when you invoke cmake, which is build system generation time). This script is careful to only update the FISH-BUILD-VERSION-FILE if the contents have changed, to avoid spurious rebuilding dependencies of FISH-BUILD-VERSION-FILE. Assuming the git version hasn't changed, the script will run, but not update FISH-BUILD-VERSION-FILE, and therefore fish_version.o will not have to be rebuilt. This might normally rebuild more than is necessary even if the timestamp is not updated, because ninja computes the dependency chain ahead of time. But Ninja also supports the 'restat' option for just this case, and CMake is rad and exposes this via BYPRODUCTS. So mark FISH-BUILD-VERSION-FILE as a byproduct and make the script always update a dummy file (fish-build-version-witness.txt). Note this is the use case for which BYPRODUCTS is designed. We also have fish_version.cpp #include "FISH-BUILD-VERSION-FILE", and do a semi-silly thing and make FISH-BUILD-VERSION-FILE valid C++ (so there's just one version file). This means we have to filter out the quotes in other cases.. 2018-01-08 17:39:45 +08:00			`// The contents of FISH-BUILD-VERSION-FILE looks like:`
