Add coveralls

[Vinatorul]

Do not merge

It works, but without yaml example
60% coverage: https://coveralls.io/github/kbknapp/clap-rs

[Vinatorul]

So it works and works well. The problem is in yaml feature

[kbknapp]

Did you mean to delete this example file?

[kbknapp]

Nice! This is something I've been wanting to add, but just haven't been too familiar with.

[Vinatorul]

Now I am just experimenting. When it will be ready - I will do a single commit :)

[Vinatorul]

Well, now it doesn't build examples and tests at all =(

[kbknapp]

Haha ok 😄

Script to avoid travis-cargo:

sudo apt-get install libcurl4-openssl-dev libelf-dev libdw-dev &&
  wget https://github.com/SimonKagstrom/kcov/archive/master.tar.gz &&
  tar xzf master.tar.gz && mkdir kcov-master/build && cd kcov-master/build && cmake .. && make &&
  sudo make install && cd ../.. &&
  kcov --coveralls-id=$TRAVIS_JOB_ID --exclude-pattern=/.cargo target/kcov target/debug/clap-*

Maybe you will see what to change here to fix it (now in checks only clap tests)

[Vinatorul]

Ready to merge

I've set threshold to 60% for now, when coverage will reach 80% - we'll set it to 80% I think.
Decrease threshold is 5% now

[kbknapp]

👍 excellent work!

[Vinatorul]

Excellent work will be when we hit 80% coverage. There is a lot of work now. And I'll start to implement some. The main problem is with false negative tests =(
