This is what you really need:
http://codepad.org/LVxUvSaF a probe
http://codepad.org/14TUDCor utilitary javascript functions that probe
references. Sorry for code quality ;)
This probe attaches to a HEAD file to make sure params are regenerated each
time it changes.
used in actual project as:
import "../../GitProbe.qbs" as GitProbe
.... later in product....
GitProbe {
id: gitProbe
sourceDirectory: project.sourceDirectory
}
cpp.defines:{
var result =base.concat([
"GIT_VERSION=" + "\"" + gitProbe.hash + "\"",
"GIT_TAG=" + "\"" + gitProbe.tag + "\"",
"GIT_COMMIT_DATE=" + "\"" + gitProbe.commitdate + "\"",
])
return result
}
and then use these defines directly in code without any generated header.
