如何从Powershell中获取最新的Mercurial标签 [英] How do I get the latest Mercurial tag from within Powershell

问题描述

如果我从DOS提示符下运行以下命令:

If i run the following command from a DOS prompt:

hg父母--template {latesttag}

hg parents --template {latesttag}

然后我得到了按预期返回的最新标签值.但是，如果我在Powershell控制台中运行相同的命令，则会出现以下错误:

then I get the latest tag value returned as expected. However if I run the same command from within a powershell console I get the following error:

汞父母:选项-i无法识别

hg parents: option -i not recognized

我需要在Powershell中运行命令，以便将其结果作为变量使用.知道我需要做什么才能使命令运行吗?

I need the command to run in powershell so I can get it's results as a variable to use. Any idea what I need to do to get the command running?

推荐答案

您只需要将--template的参数括在引号中，以使Powershell知道它是一个字符串:

You should just need to surround the argument to --template in quotes so that Powershell knows it's a string:

hg parents --template '{latesttag}'

但是，有时候，通过Powershell解析事物的方式，您必须双重确保双引号能够保留(例如，传递包含空格但应为1的参数而不是多个参数，例如路径或更长的模板):

Sometimes, however, with the way Powershell parses things you have to make doubly sure that double-quotes survive (such as passing an argument that contains spaces but should be 1 argument instead of many, like paths or a longer template):

hg parents --template '"{latesttag}"'
