setting tabwidth to 4 in git show / git diff
提问by Carlos Campderrós
At work we are several developers and don't have a code style guide, and some developers indent with tabs, and some others with 4 spaces (luckily noone of the indent with spaces people uses different than 4 spaces). In general this is no (big) problem because in our editors we set tabwidth=4and all the indentation seems correct.
在工作中，我们有几个开发人员并且没有代码风格指南，一些开发人员使用制表符缩进，而其他一些开发人员使用 4 个空格（幸运的是，没有人使用的缩进与 4 个空格不同）。一般来说，这不是（大）问题，因为在我们的编辑器中，我们设置了tabwidth=4所有缩进似乎都是正确的。
But in git diffor git showthat's what appears:
但在git diff或git show这就是出现的内容：
diff --git a/mesclatabs.php b/mesclatabs.php
new file mode 100644
index 0000000..1986c91
--- /dev/null
+++ b/mesclatabs.php
@@ -0,0 +1,5 @@
+<?php
+function foo() {
+ echo "line with 1 tab\n";
+ echo "line with 4 spaces\n";
+}
The problem is git diffor git showwhere each tabs appears as wide as 8 spaces (well, in reality appears as a tab, and the shell (bash in my case) is showing the tab as 8 spaces. I suppose there must be some bash config to change this, but I'd like to know if git has an option to output tabs as 4 spaces in diff/ show, as some developers work with zshinstead of bash.
问题是git diff或者git show每个选项卡的宽度为 8 个空格（好吧，实际上显示为一个选项卡，并且外壳（在我的情况下为 bash）将选项卡显示为 8 个空格。我想必须有一些 bash 配置可以更改这个，但我想知道 git 是否可以选择将制表符输出为diff/ 中的4 个空格show，因为一些开发人员使用zsh而不是bash.
Any ideas?
有任何想法吗？

I believe git config --global core.pager 'less -x1,5'
我相信 git config --global core.pager 'less -x1,5'

As the answer https://stackoverflow.com/a/10584237/1850340did not work for me because of my color settings I came up with following solution:
作为答案https://stackoverflow.com/a/10584237/1850340由于我的颜色设置对我不起作用，我想出了以下解决方案：
TAB=$'\t' && git config --global core.pager "sed 's/$TAB/ /g' | less" && unset TAB
This replaces all tab characters with 4 spaces before displaying it with less. (The TAB workaround is needed to circumvent the shells backslash escape)
这将用 4 个空格替换所有制表符，然后用更少的空格显示。（需要 TAB 解决方法来规避 shell 反斜杠转义）
