language: c

#-------------------------------------------------------------------------
# addons
#-------------------------------------------------------------------------
# We are using lcov for coverage analysis, so we need to install lcov
# using apt. We also need to install the newer version of gcc/g++ since
# the default version is too old.

addons:
  apt:
    sources:
      - ubuntu-toolchain-r-test
    packages:
      - lcov
      - g++-6
      - cmake
      - valgrind

#-------------------------------------------------------------------------
# install
#-------------------------------------------------------------------------
# We need to do a hack to make gcc default to
# gcc-6. Normally we would just set the CC/CXX environment variables, but
# we are not using them to simplify the Makefile we give students.

install:
  - mkdir -p latest-gcc-symlinks
  - ln -s /usr/bin/g++-6 latest-gcc-symlinks/g++
  - ln -s /usr/bin/gcc-6 latest-gcc-symlinks/gcc
  - export PATH=$PWD/latest-gcc-symlinks:$PATH

#-------------------------------------------------------------------------
# script
#-------------------------------------------------------------------------
# Build, test, and evaluate the project. We use make coverage instead of
# make check so that we generate the reports for code coverage analysis.

script:
  - gcc -g -coverage -o avg-test avg-test.c
  - ./avg-test
  - gcc -g -coverage -o gcd-test gcd-test.c
  - ./gcd-test
  - lcov --capture --directory . --output-file coverage.info
  - genhtml coverage.info --output-directory coverage-html

#-------------------------------------------------------------------------
# after_success
#-------------------------------------------------------------------------
# Assuming everything worked, we upload the coverage reports to
# codecov.io. We use -X gcov since we already ran lcov, so there is no
# need to rerun gcov.

after_success:
  - bash <(curl -s https://codecov.io/bash)
