问题
What I'm trying to do is basically:
./myProgram < myData.txt
While I'm debugging with CLion IDE. I just can't find the option to do so.
A similar question - but product-specific to MSVS
回答1:
I had the same problem and it seems that CLion is not handling standard inputs yet.
I got around this problem by changing the input stream before running my program.
As an example if you want to input a file stream inside your stdin you can write in your main:
std::ifstream in("ABSOLUTE_PATH_TO_YOUR_FILE");
std::cin.rdbuf(in.rdbuf());
Then you can find a way to toggle this stream change when you want. Note that for files you will need to provide absolute path since the application is run from a different directory than the current one.
I hope this can help until CLion provides a real solution.
回答2:
Assuming your input file is myData.txt, you can reopen/reuse the stdin stream using freopen
freopen("myData.txt","r",stdin);
if you want to do the same with your output:
freopen("myOutput.txt","w",stdout);
this will work for std::cin, printf, etc...
You can find more information about this here: http://www.cplusplus.com/reference/cstdio/freopen/
By the way, there is already a feature request for this. If you are interested, you can vote here so it gets prioritized: https://youtrack.jetbrains.com/issue/CPP-3153

For me, CLion creates the executable in a file called 'cmake-build-debug'. Check out my file structure in the pic.
Then, I just opened up my terminal and went to the directory containing the executable and used this command to pipe in the text file:
./FirstProject < ../hw1.txt
