问题描述
我正在寻找一个正则表达式来匹配每个以。开头的文件。
I'm looking for a regex to match every file begining with a "." in a directory.
我正在使用CMake（来自CMake doc： CMake需要正则表达式，而不是glob），并且想忽略每个以点开头的文件（隐藏文件），但 \ .. * 或 ^ \ .. * 不起作用：（
I'm using CMake (from CMake doc : "CMake expects regular expressions, not globs") and want to ignore every file begining with a dot (hidden files) BUT "\..*" or "^\..*" doesn't work :(
这很奇怪：这有效（由于rq的）并删除所有隐藏文件和临时文件（〜终止文件）
The strange thing : this works (thanks to rq's answer) and remove every hidden files and temp files ("~" terminated files)
file(GLOB DOT ".*")
file(GLOB TILD "*~")
set (CPACK_SOURCE_IGNORE_FILES "${DOT};${TILD}")
但是我找不到直接写到 CPACK_SOURCE_IGNORE_FILES 可以得到相同的结果！
But I can't find the right thing to write directly into CPACK_SOURCE_IGNORE_FILES to have the same result!

推荐答案
类似于GLOB的声音可能就是您想要的。
Sounds like GLOB is probably what you want.
尝试一下。打开文件 test.cmake并添加以下内容：
Try this. Open a file "test.cmake" and add the following:
file(GLOB ALL "*")
file(GLOB DOT ".*")
file(GLOB NOTDOT "[^.]*")
message("All Files ${ALL}")
message("Dot files ${DOT}")
message("Not dot files ${NOTDOT}")
然后创建几个测试文件：
Then create a couple of test files:
touch .dotfile
touch notdot
然后运行 cmake -P test.cmake。输出为：
Then run "cmake -P test.cmake". The output is:
All Files /tmp/cmake_test/.dotfile;/tmp/cmake_test/notdot;/tmp/cmake_test/test.cmake
Dot files /tmp/cmake_test/.dotfile
Not dot files /tmp/cmake_test/notdot;/tmp/cmake_test/test.cmake
已使用cmake 2.6.0进行了测试。
This was tested with cmake 2.6.0.
