From 3046c7f69a6337a971b219d047b8110e3f9ea971 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C4=90o=C3=A0n=20Tr=E1=BA=A7n=20C=C3=B4ng=20Danh?= Date: Fri, 21 Aug 2020 18:51:47 +0700 Subject: diff: index-line: respect --abbrev in object's name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A handful of Git's commands respect `--abbrev' for customizing length of abbreviation of object names. For diff-family, Git supports 2 different options for 2 different purposes, `--full-index' for showing diff-patch object's name in full, and `--abbrev' to customize the length of object names in diff-raw and diff-tree header lines, without any options to customise the length of object names in diff-patch format. When working with diff-patch format, we only have two options, either full index, or default abbrev length. Although, that behaviour is documented, it doesn't stop users from trying to use `--abbrev' with the hope of customising diff-patch's objects' name's abbreviation. Let's allow the blob object names shown on the "index" line to be abbreviated to arbitrary length given via the "--abbrev" option. To preserve backward compatibility with old script that specify both `--full-index' and `--abbrev', always show full object id if `--full-index' is specified.
