GIT_VERSION variable in .pro

[ivanicy]

Hello!!

I am trying to use the git version in my app. I found this page in which it is explained how to do it.

https://www.everythingfrontend.com/posts/app-version-from-git-tag-in-qt-qml.html

but, when I try to follow the steps, I have an error "Expected expression":

GIT_VERSION = $$system(git --git-dir $$PWD/.git --work-tree $$PWD describe --always --tags)
DEFINES += GIT_VERSION=\\"$$GIT_VERSION\\"

...

ui->labelVersion->setText(QString("App (version %1)").arg(QString(GIT_VERSION))); // <-- Expected expression

What I am doing wrong?

Thank you very much!

@ivanicy said in GIT_VERSION variable in .pro:

DEFINES += GIT_VERSION=\"$$GIT_VERSION\"

change to: DEFINES += GIT_VERSION=\\\"$$GIT_VERSION\\\"
And then it should work

@KroMignon Thank you very much!!

[KroMignon]

@ivanicy your welcome ;) Don't forget to mark as solved!

[ivanicy]

@KroMignon And do you know how can I add the git date to this string?

[KroMignon]

@ivanicy You can try something like this:

GIT_DATE=$$system(git --git-dir $$PWD/.git --work-tree $$PWD log -n 1 --pretty=%cd --date=iso)
DEFINES += GIT_DATE=\\\"$$GIT_DATE\\\"

Hi,

Note that this escaping might not apply to all OSs (thinking about Windows).

[ivanicy]

@KroMignon I get "expected expression" error again when I try to use it. But I don't know why because It is used the same as the other.

I changed "$$PWD/.git" to "&&PWD\..\.git" because this is my git directory. This change works with the GIT_VERSION variable.

@ivanicy Good read, I have copy this from your previous post... but if you problem is solved, don't forget to mark this thread as solved too.

[ivanicy]

@KroMignon But I am getting error with the GIT_DATE variable and I don't know why.

GIT_DATE = $$system(git --git-dir $$PWD\..\.git --work-tree $$PWD log -n 1 --pretty=%cd --date=iso)
DEFINES += GIT_DATE=\\\"$$GIT_DATE\\\"

I get "expected expression"

Thank you for your help

@ivanicy Have tried to search GIT_DATE= in the compilation output windows in QtCreator?

[ivanicy]

@KroMignon In the Compile output GIT_DATE has the correct value. But when I try to use it, it is as if the variable was not recognized.

[KroMignon]

@ivanicy Can you show me what you see in the window?

[ivanicy]

@KroMignon Yes, of course. This is the GIT_DATE value in Compile Output window:

[KroMignon]

@ivanicy I would suggest you to change you C++ as follow:

ui->labelVersion->setText(QString("Add (version %1)").arg(GIT_VERSION));

Perhaps you can also try out other date formats in your PRO file:

GIT_DATE = $$system(git --git-dir $$PWD\..\.git --work-tree $$PWD log -n 1 --pretty=%cd --date=iso)
GIT_DATE = $$system(git --git-dir $$PWD\..\.git --work-tree $$PWD log -n 1 --pretty=%cI)
GIT_DATE = $$system(git --git-dir $$PWD\..\.git --work-tree $$PWD log -n 1 --pretty=%ci)

Hi.
Please, check my repo. Set Qt App version from git.
