# linuxbrew (for hugo)
- git clone https://github.com/Homebrew/brew ~/.linuxbrew/Homebrew
- mkdir ~/.linuxbrew/bin
- ln -s ~/.linuxbrew/Homebrew/bin/brew ~/.linuxbrew/bin
- eval $(~/.linuxbrew/bin/brew shellenv)

# hugo (for documentation)
- brew install hugo
# print hugo version (useful for debugging documentation build errors)
- hugo version

before_script:
# Set the server config to `testing`. This is required for for the UTs to pass.
- python monkey/monkey_island/cc/environment/set_server_config.py testing

script:
# Check Python code
## Check syntax errors and fail the build if any are found.
- flake8 . --count --select=E901,E999,F821,F822,F823 --show-source --statistics

## Warn about linter issues.
### --exit-zero forces Flake8 to use the exit status code 0 even if there are errors, which means this will NOT fail the build.
### --count will print the total number of errors.
### --statistics Count the number of occurrences of each error/warning code and print a report.
### The output is redirected to a file.
- flake8 . --count --exit-zero --max-complexity=10 --max-line-length=127 --statistics > flake8_warnings.txt
## Display the linter issues
- cat flake8_warnings.txt
## Make sure that we haven't increased the amount of warnings.
- PYTHON_WARNINGS_AMOUNT_UPPER_LIMIT=120
- if [ $(tail -n 1 flake8_warnings.txt) -gt $PYTHON_WARNINGS_AMOUNT_UPPER_LIMIT ]; then echo "Too many python linter warnings! Failing this build. Lower the amount of linter errors in this and try again. " && exit 1; fi

## Check import order
- python -m isort . -c -p common -p infection_monkey -p monkey_island

## Run unit tests
- cd monkey  # This is our source dir
- python -m pytest  # Have to use `python -m pytest` instead of `pytest` to add "{$builddir}/monkey/monkey" to sys.path.

## Calculate Code Coverage
- coverage run -m pytest

# Check JS code. The npm install must happen AFTER the flake8 because the node_modules folder will cause a lot of errors.
- cd monkey_island/cc/ui
- npm ci  # See https://docs.npmjs.com/cli/ci.html
- eslint ./src --quiet  # Test for errors
- JS_WARNINGS_AMOUNT_UPPER_LIMIT=28
- eslint ./src --max-warnings $JS_WARNINGS_AMOUNT_UPPER_LIMIT  # Test for max warnings

# Build documentation
- cd $TRAVIS_BUILD_DIR/docs
- hugo --verbose --environment staging
