For now, just give a hint about how these hooks will be run in 'git hook list'. Later on, though, we will pay attention to this enum when running the hooks. --- Notes: Since v7, tidied up the behavior of the HOOK_UNKNOWN flag and added a test to enforce it - now it matches the design doc much better. Also, thanks Jonathan Tan for pointing out that the commit message made no sense and was targeted for a different change. Rewrote the commit message now. Plus, added HOOK_ERROR flag per Junio and Jonathan Nieder. - Emily Documentation/config/hook.txt | 5 +++ builtin/hook.c | 69 +++++++++++++++++++++++++++++++--- hook.c | 24 ++++++++++++ hook.h | 16 ++++++++ t/t1360-config-based-hooks.sh | 71 +++++++++++++++++++++++++++++++++++ 5 files changed, 180 insertions(+), 5 deletions(-) diff --git a/Documentation/config/hook.txt b/Documentation/config/hook.txt index 71449ecbc7..75312754ae 100644 --- a/Documentation/config/hook.txt +++ b/Documentation/config/hook.txt @@ -7,3 +7,8 @@ hookcmd.<name>.command:: A command to execute during a hook for which <name> has been specified as a command.
