Currently there is no way to specify a tree-ish to read the gitattributes from. This is specifically useful in bare repositories wherein the gitattributes are only present in the git working tree but not available directly on the filesystem. This series aims to add a new flag `--source` to git-check-attr(1) which allows us to read gitattributes from the specified tree-ish. Changes since v5: - Changed the documentation and helper code to say 'tree-ish' instead of 'tree' - Fixed broken tests because of missing `&&` Range-diff against v5: 1: 6224754179 = 1: 6224754179 t0003: move setup for `--all` into new block 2: d835d989ad ! 2: 57f5957127 attr: add flag `--source` to work with tree-ish @@ Documentation/git-check-attr.txt: git-check-attr - Display gitattributes informa [verse] -'git check-attr' [-a | --all | <attr>...] [--] <pathname>... -'git check-attr' --stdin [-z] [-a | --all | <attr>...] -+'git check-attr' [--source <tree>] [-a | --all | <attr>...] [--] <pathname>... -+'git check-attr' --stdin [-z] [--source <tree>] [-a | --all | <attr>...] ++'git check-attr' [--source <tree-ish>] [-a | --all | <attr>...] [--] <pathname>... ++'git check-attr' --stdin [-z] [--source <tree-ish>] [-a | --all | <attr>...] DESCRIPTION ----------- @@ Documentation/git-check-attr.txt: OPTIONS If `--stdin` is also given, input paths are separated with a NUL character instead of a linefeed character. -+--source=<tree>:: -+ Check attributes against the specified tree-ish.
