黄瓜：管输出不失颜色 [英] Cucumber: pipe output without losing color

问题描述

我使用 cucumber 运行一些测试。它使用ANSI转义对其输出进行着色。这是伟大的，但目前它产生更多的产出比我关心，和推的东西，我在屏幕上关心。似乎没有办法消除黄瓜内的其他行，但我可以通过 grep 管道输出到我关心的。 / p>

这个解决方案的缺点是，所有的颜色都丢失了。我知道这不是我的shell或grep的错，因为％echo\e [35mhello\e [00m world] | grep hello 工作正常，所以它必须是黄瓜以某种方式禁用自己的颜色。

如何管理彩色输出黄瓜的输出？

解决方案

Doh。它包含在 cucumber -h 中。使用 -c 标志强制彩色输出。

I'm using cucumber to run some tests. It colorizes its output using ANSI escapes. This is great, but currently its producing more output than I care about, and shoving things I do care about off the screen. There doesn't seem to be a way to eliminate the other lines from within cucumber, but I can pipe the output through grep to pare down to the ones I care about.

The downside of this solution, though, is that all the colors are lost. I know it's not my shell or grep's fault, because % echo "\e[35mhello\e[00m world" | grep hello works just fine, so it must be cucumber disabling its own color somehow.

How can I preserve the colored output when I pipe the output of cucumber?

解决方案

Doh. It's covered in cucumber -h. Use the -c flag to force colorized output.
