作为Qt项目部署过程的一部分,我需要将几个文件复制到部署文件夹。我的问题是我无法让-= operator工作。我还想根据文件名过滤掉特定文件。
为了重现我的问题,我创建了一个简单的Qt项目,其.pro文件如下所示(参见"感兴趣的部分"):
TEMPLATE = app
QT = core
CONFIG += console
CONFIG -= app_bundle
CONFIG += c++11
SOURCES += main.cpp \
myfile1.cpp \
myfile1d.cpp
SOURCES += myfile1.cpp
SOURCES += myfile1d.cpp
#portion of interest - start
FOLDER_PATH = $$_PRO_FILE_PWD_/../files/
#add all files present in 'files' folder
FILES_TO_COPY = $$FOLDER_PATH/*
#exclude a specific file
win32:CONFIG(release, debug|release): {
FILES_TO_COPY -= $$FOLDER_PATH/filecd.txt
}
filesToCopy.files = $$FILES_TO_COPY
filesToCopy.path = $$_PRO_FILE_PWD_/../deploy
INSTALLS += filesToCopy
#portion of interest - finish
我添加了一个" make install"步骤到Qt Creator项目设置中的构建过程。此步骤应查看.pro文件中的INSTALLS变量,并从'文件中复制指定的文件。部署'夹。
现在,文件夹'文件'包含以下文件:
这是我想做的事情:
1)最初,我想要除了' filecd.txt'之外的所有文件。要从'文件中复制'部署'。我正在尝试使用' - ='排除' filecd.txt'但是我仍然会复制所有文件。
2)我还想根据他们的名字过滤掉特定的文件。例如,如果我们处于发布模式,则不应复制文件的调试版本。这应该排除filecd.txt和filedd.txt,它们被模拟为filec.txt和filed.txt的调试版本。
感谢您的帮助。

更新: 对于其他尝试做类似事情的人(以及有经验的人进行审查),这就是我最终做的事情:
#add all files present in 'files' folder
FILES_TO_COPY = $$files($$FOLDER_PATH/*)
#From these files: fileb.txt filec.txt filecd.txt filed.txt filedd.txt
#we only want to copy the following files to the deployment folder
#fileb.txt filec.txt filed.txt
#i.e., we wish to exclude these files from deployment folder:
#filecd.txt filedd.txt
win32:CONFIG(release, debug|release): {
#FILES_TO_COPY -= $$FOLDER_PATH/filecd.txt
for(iter, FILES_TO_COPY): {
#name of one file
FNAME = $$iter #/path/to/filecd.txt
SEARCH_TOKEN = 'd.txt'
SECTIONS = $$split(FNAME, $$SEARCH_TOKEN)#filec d.txt
FNAME1 = $$first(SECTIONS) #filec
#if 'd.txt' is not part of the filename then split returns
#the filename untouched (i.e. FNAME1 would be equal to FNAME,
#and should be found in FILES_TO_COPY)
#NOTE: If we are unlucky enough to have another file called
#'filec' (without any extension) then the search for filecd.txt
#will be abandoned.
!contains(FILES_TO_COPY, $$FNAME1) : {
FILE_EXT = '.txt'
FNAME1D = $$join(FNAME1, , , $$FILE_EXT) #filec.txt
contains(FILES_TO_COPY, $$FNAME1D): {
REDUNDANT_FILES += $$FNAME
}
}
}
}
FILES_TO_COPY -= $$REDUNDANT_FILES
filesToCopy.files = $$FILES_TO_COPY
filesToCopy.path = $$_PRO_FILE_PWD_/../deploy
INSTALLS += filesToCopy
答案 0 :(得分:1)
qmake在解析文件后执行glob扩展,因此当解析FILES_TO_COPY -= ...
行时,变量仍然具有未扩展的glob值。
相反,使用$$files
内置测试功能来组合您可以从中删除的文件列表:
FILES_TO_COPY = $$files($$FOLDER_PATH/*)
win32:CONFIG(release, debug|release): {
FILES_TO_COPY -= $$FOLDER_PATH/filecd.txt
}

您可以使用正则表达式删除变量,使其更整洁:
FILES_TO_COPY ~= .*filecd.txt
