From b2d3fd287b60aae963d683f89f24dc6cb97520f8 Mon Sep 17 00:00:00 2001 From: Kevin Daudt Date: Mon, 16 Oct 2017 20:35:11 +0200 Subject: column: show auto columns when pager is active MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When columns are set to automatic for git tag and the output is paginated by git, the output is a single column instead of multiple columns. Standard behaviour in git is to honor auto values when the pager is active, which happens for example with commands like git log showing colors when being paged. Since ff1e72483 (tag: change default of `pager.tag` to "on", 2017-08-02), the pager has been enabled by default, exposing this problem to more people. finalize_colopts in column.c only checks whether the output is a TTY to determine if columns should be enabled with columns set to auto. Also check if the pager is active. Adding a test for git column is possible but requires some care to work around a race on stdin. See commit 18d8c2693 (test_terminal: redirect child process' stdin to a pty, 2015-08-04). Test git tag instead, since that does not involve stdin, and since that was the original motivation for this patch.
