How can I use branch-specific variables in Travis CI?

In Travis CI, you can define branch-specific environment variables in your .travis.yml file. You can use the env key to set variables that are specific to certain branches.

Can you give me an example of how to set that up?

Sure! Here's an example:

branches:
  only:
    - main
    - develop

env:
  global:
    - COMMON_VAR=value
  matrix:
    - BRANCH_VAR=value_for_branch if [ "$TRAVIS_BRANCH" == "main" ]
    - BRANCH_VAR=value_for_develop if [ "$TRAVIS_BRANCH" == "develop" ]

What happens if I push to a different branch?

If you push to a branch that isn't specified in your .travis.yml, the environment variables for that branch won't be set, and it will use the global variables instead.
