From 7e29b8254f08af820b2f0c3770836638ffe517ab Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sat, 21 Apr 2012 11:44:32 +0700 Subject: Add column layout skeleton and git-column MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A column option string consists of many token separated by either a space or a comma. A token belongs to one of three groups: - enabling: always, never and auto - layout mode: currently plain (which does not layout at all) - other future tuning flags git-column can be used to pipe output to from a command that wants column layout, but not to mess with its own output code. Simpler output code can be changed to use column layout code directly.
