There are a bunch of different situations in which one would like to have an absolute and canonical or a relative path from Git. In many of these cases, these values are already available from git rev-parse, but some values only come in one form or another. Many operating systems, such as macOS, lack a built-in realpath command that can canonicalize paths properly, and additionally some programming languages, like Go, currently do as well. It's therefore helpful for us to provide a generic way to request that a path is fully canonicalized before using it. Since users may wish for a relative path, we can provide one of those as well. Changes from v1: * Add a function to handle missing trailing components when canonicalizing paths and use it. * Improve commit messages. * Fix broken && chain. * Fix situation where relative paths are not relative. brian m. carlson (2): abspath: add a function to resolve paths with missing components rev-parse: add option for absolute or relative path formatting Documentation/git-rev-parse.txt | 71 ++++++++++++--------- abspath.c | 50 +++++++++++++-- builtin/rev-parse.c | 105 ++++++++++++++++++++++++++++---- cache.h | 1 + t/t1500-rev-parse.sh | 57 ++++++++++++++++- 5 files changed, 237 insertions(+), 47 deletions(-)
