Implement support for version from last git commit

[pramodk]

• coreneuron version was printed as "version id unimplemented"
• add cmake module GitRevision.cmake to find git commit information
• this commit adds support to print project version along with
  git commit and it's date. e.g.
  Version : 0.21.0 bd747a8 (14-09-2020 16:03)

@nrnhines : until this gets merged, may be you can just cherry-pick this commit into your branch and test your NEUERON PR?

Strange puzzle. I checked out this pull request Your branch is up to date with 'origin/pramodk/version-info' and

hines@hines-T7500:~/neuron/acell-thread/external/coreneuron$ git log
commit 2521f568c3eeb468700f0fafbc9b28b30622996b (HEAD -> pramodk/version-info, origin/pramodk/version-info)

Finally, for NEURON,

hines@hines-T7500:~/neuron/acell-thread$ git show HEAD
commit c7c28a2679172382df76f4d735001a97bee290b3 (HEAD -> acell-thread)
Author: Michael Hines <michael.hines@yale.edu>
Date:   Tue Sep 15 09:38:16 2020 -0400

    Update to use coreneuron with version info.

diff --git a/external/coreneuron b/external/coreneuron

But when I build and launch, I get the nrn version output instead of the coreneuron version. ie.

By the way, if I launch nrniv-core -h the version is not printed and after all the option help is printed it ends with Aborted (core dumped)

Did you commit the commit submodule before launching cmake command? Let me try it and see what's happening.

I have now added --version option in nrniv-core:

$ ./bin/nrniv-core --version
CoreNEURON Version : 0.21.0 2521f56 (2020-09-15 01:09:14 +0200)

seems like --help was not properly handled. I have changed logic a bit and now it exit cleanly.

That is interesting as

    Added --version CLI flag

and when I do a fresh build from an empty bldtst

hines@hines-T7500:~/neuron/acell-thread/bldtst$ cmake .. -DCMAKE_INSTALL_PREFIX=install -DNRN_ENABLE_CORENEURON=ON -DNRN_ENABLE_TESTS=ON -DIV_DIR=$HOME/neuron/ivcmake/build/install
...
make -j install
...
hines@hines-T7500:~/neuron/acell-thread/bldtst$ which nrniv-core
/home/hines/neuron/acell-thread/bldtst/install/bin/nrniv-core
hines@hines-T7500:~/neuron/acell-thread/bldtst$ nrniv-core --version
CoreNEURON Version : 0.21.0 c7c28a26 (2020-09-15 09:38:16 -0400)

So there must be something stupidly obvious that I'm missing.

I wonder if, when one builds coreneuron as a submodule, the git commands from within the nrn build folder are getting some nrn git info instead of from nrn/external/coreneuron

Ahh yes! my bad! I am using CMAKE_SOURCE_DIR which will be nrn directory with submodule:

  execute_process(
    COMMAND ${GIT_EXECUTABLE} log -1 --format=%h
    WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}
    OUTPUT_VARIABLE GIT_REVISION_SHA1
    ERROR_QUIET OUTPUT_STRIP_TRAILING_WHITESPACE)
  # get last commit date
  execute_process(
    COMMAND ${GIT_EXECUTABLE} show -s --format=%ci
    WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}
    OUTPUT_VARIABLE GIT_REVISION_DATE
    ERROR_QUIET OUTPUT_STRIP_TRAILING_WHITESPACE)
