Pre-built Emacs binaries for Travis CI.

Usage

Add the following to your .travis.yml:

language: generic

# This is the default, make it explicit so that we are not caught by a
# change in the default.
os: linux
dist: xenial

env:
  jobs:
    - EMACS_VERSION=23.4
    - EMACS_VERSION=24.5
    - EMACS_VERSION=25.3
    - EMACS_VERSION=master

jobs:
  allow_failures:
    - env: EMACS_VERSION=master

install:
  - curl -LO https://github.com/npostavs/emacs-travis/releases/download/bins/emacs-bin-${EMACS_VERSION}.tar.gz
  - tar -xaf emacs-bin-${EMACS_VERSION}.tar.gz -C /
  # Configure $PATH: Emacs installed to /tmp/emacs
  - export PATH=/tmp/emacs/bin:${PATH}
  # Install dependencies for older Emacs versions which lack them.
  # Introduced in Emacs 24.3.
  - if ! emacs -Q --batch --eval "(require 'cl-lib)" ; then
        curl -Lo cl-lib.el http://elpa.gnu.org/packages/cl-lib-0.6.1.el ;
    fi
  # Introduced in Emacs 24.1
  - if ! emacs -Q --batch --eval "(require 'ert)" ; then
        curl -LO https://raw.githubusercontent.com/ohler/ert/c619b56c5bc6a866e33787489545b87d79973205/lisp/emacs-lisp/ert.el &&
        curl -LO https://raw.githubusercontent.com/ohler/ert/c619b56c5bc6a866e33787489545b87d79973205/lisp/emacs-lisp/ert-x.el ;
    fi
  - emacs --version

script:
  - make
  - make check

This setup tests your Emacs Lisp project on Emacs 23.4, 24.5, 25.3, and the latest Emacs master version (assuming you have a Makefile with a check target which runs your tests). It includes code for installing cl-lib and ert for older Emacs versions, you can remove those steps if your package/tests don't depend on them (or your package requires newer Emacs versions which already include them).

All point releases starting from 23.4 are also available if you want to test more versions in between. Daily builds of from the git repository branches master and emacs-27 are available as versions master and 27, respectively. The latest pretest or release candidate from the emacs-27 branch is available as version 27-prerelease (this is updated manually, so may lag by a few days).
