Use of variables like %{buildDir} in QtCreator kit settings in Qt5

qt variables qt5 qt-creator eval
Lennart Rolland picture Lennart Rolland · Mar 13, 2016 · Viewed 7.5k times · Source

In this documentation (under section "Specifying a Custom Executable to Run") I noticed that there is mention of what looks like a variable %{buildDir} in the field "Working directory".

enter image description here

I have struggled for a while now to find documentation for this feature. I would like to know first of all is there documentation for this somewhere?.

Secondary questions:

  • What other variables are available?
  • In which fields can they be used?
  • Can I access variables that I created in my project's .pro file?
  • Are there any other eval features or is this mechanism limited to variables?

Thanks!

As mentioned in the comments there is a "variables" button... supposedly for use all over the qt environment. However I have only found it available in obscure places that are not very useful!

However, you can at least get the list of vars from these places and use them where you actually need them. To find this, navigate to:

  • Tools (menu) --> Options --> Environment (tab) --> External Tools
  • Click "Update Translations..."
  • Click inside "Working Directory.." and you should see a "AB->" icon in colour to the right.
  • Click the icon for your list of vars.

You will notice that the style is a little different then %{BuildDir} but I believe the equivalent is %{CurrentProject:BuildPath} - You can see on the second screen shot I have right clicked and it asks you what you want to insert (the variable, or the value of the variable).

Annoyingly I could not figure out how to copy / paste the whole list as it is single line click only... maybe someone more clever can figure that out and we can stick that list in some Qt wiki :o

Here are the screen shots... Notice in screen shot 1 the little icon at the right side of "Working Directory" text-edit box.
