Running a test via bash script

[nakib]

Hello, all!

I want start by thanking the developers for this very useful tool.

I am using fpm to build my own project, elphbolt (https://github.com/nakib/elphbolt). Compared to cmake, I faced one difficulty with fpm related to running a regression test. For elphbolt, and perhaps for a lot of other codes, one needs to prepare a a directory tree with the necessary input files before running a parallel job. I do this with a script as shown below:

#!/bin/bash

# Download data from public repo
curl -X GET "https://nomad-lab.eu/prod/v1/api/v1/uploads/5b-c4JYRSG6qitMFjFUUzQ/raw/?offset=0&length=-1&compress=true" -o 3C-SiC.zip

#Extract data
unzip 3C-SiC.zip
rm 3C-SiC.zip

workdir="./3C-SiC_test_output"
datadir="./3C-SiC/elphbolt_input_data"
inputdir="../test/3C-SiC"

mkdir $workdir
cp $datadir/* $workdir
cp $inputdir/input.nml $workdir
rm -r 3C-SiC
cd $workdir

#gcc+opencoarrays
# if test fails, propagate the error
cafrun -n 2 test_bte_regression || exit -1

cd ..

With cmake, I can add the following to the CMakeLists.txt to run this script:

...

find_program (bash /bin/bash)
if(bash)
  if(CMAKE_Fortran_COMPILER MATCHES "caf")
    add_test (bte_regression bash ../test/3C-SiC/run_bte_caf.sh)
  endif()
endif(bash)

However, I could not find out how I could achieve this with fpm. It seems like fpm does not allow executing external scripts at the moment, as mentioned here: #923. Would the developers consider adding this feature?

Best regards,
Nakib
