问题 I have two possible build options. As I don't want my clients to start the installer with some parameters, I'd better pass them to the compiler and do all the job in my code. Let's say I have the variable UNION which may take two values: 0 and 1 . I have to analyze the value of that variable in my code and depending on the result to include some files or not. I know how to pass parameterrs to the installer itself, but how can I pass them to the compiler? Here's some code: procedure

问题 Are their any conventions (either written or just generally understood) for when to use a forward slash (/) or a hyphen (-) when reading arguments/flags from a command line? C:\> myprogram.exe -a C:\> myprogram.exe /a The two seem to be interchangeable in my experience, but I haven't used enough command line tools to say I've spotted any rules or patterns. Is there a good reason that either of them are used at all? Could I theoretically use an asterisk (*) if I wanted to? 回答1: You can

问题 On the PyCharm Help Website I see you can use PyCharm as a diff tool from the Command Line to compare two files. That's awesome! However is there a way to take it a step further and use it as a git diff tool. So I can just type pycharm diff file_name.py and get the GIT differences same way you would if you were on PyCharm have setup the GIT integration and press CTRL + D to see the differences. 回答1: Yes you can. First you need to enable the command-line launcher: To enable invoking PyCharm
