## Notifications
## The default is to send email on all failures and changed success
## Adding other notifiers (like IRC) does not disable the email one
notifications:
  ## This is, in fact, the default email setting so it is unnecessary.
  ## It would probably be too annoying to set on_success: always
  email:
    on_success: changed
    on_failure: always
  ## Are we going to want this on or off?
  irc:
    # TMW irc doesn't work for some reason; freenode does ...
    # I'm leaving it like this because it's what I'd like to use.
    channels:   "irc.themanaworld.org#tmw-dev"
    on_success: always
    on_failure: always

## Commands before installing prerequisites
before_install: export CC=${REAL_CC} CXX=${REAL_CXX}
# before_install: git submodule update --init --recursive

## Install prerequisites
install:
# if > or | folding is used, error
# but YAML folds by default on this, so it works (I hope)

## Do something before the main test script

## Main test script
script:
  - make -k -j2 CC=${REAL_CC} CXX=${REAL_CXX}

## Do something after the main test script
# after_script: ...

### The rest of the file creates a build matrix
### containing gcc-4.4 through gcc-4.7 and clang-3.1

## This doesn't work - travis defaults to plain gcc if unknown
# compiler: gcc-4.4
# compiler: gcc-4.5
# compiler: gcc-4.6
# compiler: gcc-4.7
# compiler: clang

## Environment variables to expand the build matrix
## Needed because compiler: gcc overwrites CC and CXX
env:
  - REAL_CC=gcc-4.4 REAL_CXX=g++-4.4
  - REAL_CC=gcc-4.5 REAL_CXX=g++-4.5
  - REAL_CC=gcc-4.6 REAL_CXX=g++-4.6
  - REAL_CC=gcc-4.7 REAL_CXX=g++-4.7
  - REAL_CC=clang   REAL_CXX=clang++
