Use in Travis-CI

The below example is to use bashvm in Travis-CI.

sudo: false
cache:
  directories:
  - .bashvm/usr
env:
- RUN_BASH_VERSION=3.1
- RUN_BASH_VERSION=3.2
- RUN_BASH_VERSION=4.0
- RUN_BASH_VERSION=4.1
- RUN_BASH_VERSION=4.2
- RUN_BASH_VERSION=4.3
install:
- mkdir -p .bashvm
- curl  https://codeload.github.com/ueokande/bashvm/tar.gz/master | tar zx
- cp -r bashvm-master/* .bashvm/
before_script:
- export BASHVM_HOME=$(readlink -f  .bashvm)
- source .bashvm/bin/bashvm-init
- bashvm use --install $RUN_BASH_VERSION
script:
- bash your_test_script.sh

This examples use container-based infrastructure to enable caching directories in order to reduce build time of bash versions. In this example, $TRAVIS_BUILD_DIR/.bashvm/usr directory which contains built bash versions is cached. In install step, the archive of bashvm is downloaded by curl instead of git-clone. These commands allow to fetch the sources successfully under caching directories.

The build script run for each RUN_BASH_VERSION versions. The bash version is installed and switched in before_script, and the switched version is enabled on script.
