Current year in Qt pro file

[Cobra91151]

Hi! I want to get current year in qt pro file to display it in QMAKE_TARGET_COPYRIGHT variable.
I have tried with $$system("date") but it doesn't work.
How to do it? Thanks in advance.

Hi,

What is your code exactly ?

[Cobra91151]

@SGaist

My code:

QMAKE_TARGET_COPYRIGHT = $$system("date /T")
message($$QMAKE_TARGET_COPYRIGHT)

It returns:
Project MESSAGE: Fri 02/17/2017
When I use just $$system("date") it can't read the Qt project.

I need to pass some parameter to get just - 2017.

@Cobra91151 What about

date +%Y

see: man date
Update: you're on Windows?

@jsulm

Yes.
I have tried your code:

QMAKE_TARGET_COPYRIGHT = $$system("date +%Y")
message($$QMAKE_TARGET_COPYRIGHT)

After pro file is saved it can't read my project. It stuck on - Reading Project....

Update:
Also I have tried to create console application to test it. If I'm right that $$system() function in Qt is the same as is system() (C++) when use it in Visual Studio project. So:

Visual Studio Console Project Code:
system("date") - returns: The current date is: Fri 02/17/2017 (not working in Qt pro)
system("date /T") - returns: Fri 02/17/2017 (working in Qt pro)

So I think system("date /T") should be, but I need also some parameter to display just year.

well date +%Y does
date +%Y

so that is why its hanging :)

Date command do not mention ANY way to change the format. ( in help)

@mrjj

So there no way to get current year in QMAKE_TARGET_COPYRIGHT?

[Cobra91151]

I have found a solution. Code:
QMAKE_TARGET_COPYRIGHT = $$system("echo %date:~10,4%")
message($$QMAKE_TARGET_COPYRIGHT)

It returns 2017.

@Cobra91151

clever :)
since the length should remain the same, cutting should work
across languages etc. i hope.

@Cobra91151 date +%Y is for Linux, that's why I asked about Windows :-)
