This is a clone of FRUIT_3.3.7. I'm new to Ruby, Rake and Cucumber. But this looks like a good start for some testing I need to do in porting some legacy code to a new compiler. Also looks like a good way to learn more about Ruby and friends.

I don't have plans at the moment to do a lot with the internals of FRUIT beyond getting it to work reliably with the Lahey 7.0 Compiler. I fix things here when I need to.

Original README

#Installation guide:

1. Untar the gz file

2. Put Ruby in your path.

3. Install rake gem
    gem install rake

4. Install fruit_processor gem
    cd fruit/fruit_processor_gem
    rake install

5. You may need to change your compiler from Intel FORTRAN to other
   modify this line in rake_base.rb :
     $compiler = 'ifort'
   $option = "-check all -warn all"

 By default, ifort is used if available.
 If ifort is abesnt, gfotran or FTN95 is used.

6. Build and run all the test
  cd fruit
  rake

(By default a sample sample_single_dir is omitted,
 because some old compilers does not accept *.f95 extension. Try
   rake sample_single_dir
 to run it.)

Samples:

in_3_minutes A sample of manually written driver. * fruit.f90 must be copied to in_3_minutes beforehand.

sample Multi-directry test. Tester codes are in fruit-x.x.x/sample/test directry. Before running the test, tested code (fruit-x.x.x/sample/src/calculator.f90) and fruit code (fruit-x.x.x/src/fruit.f90) must be compiled into lib*.a archives. * libfruit.a needed. To prepare it, run "rake compile" in fruit-x.x.x directry for libfruit.a.

sample_single_dir Dependency between Fortran codes is estimated by "rake_estimate.rb" loaded from sample_single_dir/rakefile. see fruit-x.x.x/sample_single_dir/README. Tester code : sample_single_dir/mystack_test.f95 Tested code : sample_single_dir/mystack.f95, Z_constants.f95

sample_selective Testers to call is specifiled in a line in sample_selective/rakefile: fp.process_only = FileList["mydict_test.f90"] This sample also shows that test can be built even when main program (dummy_main.f90) exists. Dependency between Fortran codes is estimated by "rake_estimate.rb". Tester code: fruit-x.x.x/sample_selective/*_test.f90 Tested code: fruit-x.x.x/sample_selective/constant.f90, mydict.f90

sample_build_dir This sample shows build directry may differ from source directry. It also shows that test can be built even when main program (main.f90) exists. Tester code : fruit-x.x.x/sample_build_dir/atoz_test.f90 Tested code : fruit-x.x.x/sample_build_dir/atoz.f90 Build test in fruit-x.x.x/sample_build_dir/build_unittest

sample_multi_dir Tester codes and tested codes are in different directries. Sample of building only selected testers are build in "build_selective" directry and that of all testers are built in "build" directry. Tester codes: fruit-x.x.x/sample_multi_dir/test/.f90 Tested codes: fruit-x.x.x/sample_multi_dir/src/.f90 Build is done in fruit-x.x.x/sample_multi_dir/build/ Selective build: fruit-x.x.x/sample_multi_dir/build_selective/

self_test Test of fruit.f90 itsef.
