It would be nice to be able to include the Git ID information in the built LabVIEW appliction.
The Project build specs provides a way to do some action prior to the build. A so called "Pre-Build Action.vi" can be used to get the Git ID information.
A shell script can be run, here is an example that I used for an mplab project.
echo "#define BUILDNUMBER_STR " > gitbuild.h
"c:/Program Files (x86)"/Git/bin/git describe --tags >> gitbuild.h
echo -e "\r\n// End of File" >> gitbuild.h
The important features:
1. Create the C define in a .h file.
2. Use the GIT describe command with --tags to get the git ID with tag number, commit number and part of the hash code associated with the tag.
Example: V1x6Final-1-g3fbdc98
(Tag, Commit #, Hash code --- V1x6Final, 1, g3fbdc98)
For Labview just the string from the "git describe --tags" is needed. The Pre-Build Action.vi, can be used to read up the string.
Frankly, I would be inclined to nest a GetGitID.vi to be called by Pre-Build Action.vi and put all the code to do the shell script and read the result string in it.
This blog post has resulted in a project with a sample VI. The zip file contains all the materials to pre build a git id, to save it and have it for use. It is tested under LabVIEW 2012 only. Tests on 2010 failed.
