我尝试用vscode设置一个基于stack的Haskell IDE,从一个用stack init创建的小项目开始,然后在src中添加第二个模块,并在package.yaml中添加一些依赖项。它构建正常,但当我启动stack ghci时,我会收到警告:
Warning: Multiple files use the same module name:
* Paths_primo found at the following paths
* /home/frank/Workspace11/primo/.stack-work/dist/x86_64-linux
我想在我的linux盒中做这样的事情:
if [[ colors exist ]];then
echo "some text in colors"
fi
我的怀疑是:
我使用sed为某些文本在日志文件中放置颜色,但是如果linux框没有启用颜色,它会以不方便的方式修改日志文件,比如放置一些不必要的字符,比如[033m ]等等。
我想列出CM的配置值。所以我的代码可以在不同的集群(5.9.1,5.10.0和5.8.3)上运行:
from cm_api.api_client import ApiResource
cm_host = "XX.XX.70.12"
api = ApiResource(cm_host, username="supervision-user", password="XXXXXX" )
cm_config = api.get_cloudera_manager().get_config(view='full')
for item i
我运行了几个测试,最后运行Valgrind来验证库的内存使用情况。Valgrind一直在抱怨:
==27022== HEAP SUMMARY:
==27022== in use at exit: 6,139 bytes in 3 blocks
==27022== total heap usage: 609 allocs, 606 frees, 19,877,073 bytes allocated

我正在从Valgrind获取以下日志:
