This is the successor / continuation of the r-travis repository, which is itself a maintained fork of the (now deprecated) original r-travis repository by Craig Citro et al. I was an early contributor to this project, and quite like its design and features -- so I have been keeping it around, maintained and extended it. It is my 'go-to' CI setup for a few dozen repositories affecting a fairly decent number of users.
See the r-ci webpage for a brief overview of usage with GitHub Actions, Travis, Azure DevOps and Docker. See this r^4 blog post for a short video and background slides.
A minimal example of use with Travis follows:
language: c
sudo: required
dist: focal
before_install:
- curl -OLs https://eddelbuettel.github.io/r-ci/run.sh && chmod 0755 run.sh
- ./run.sh bootstrap
install:
- ./run.sh install_deps
script:
- ./run.sh run_testsThis downloads the run.sh script, uses it to bootstrap the test environment, then installs
dependencies via install_deps and finally runs tests. For a realistic but real example see e.g.
this .travis.yml file of package
digest. For another example, see
package tidyCpp which shows how to use the run.sh
script with Travis CI as well as
with GitHub
Actions, or
package dang (featured in the
video mentioned above) Numerous variations are possible: running
'test matrices' across macOS and Linux, using BSPM for binaries (both of those are used by
digest, running with several g++
versions (as used by
RcppSimdjson, ...).
We also use the same approach of downloading run.sh and invoking it for the different steps in
with GitHub Actions (e.g. for
tidyCpp). Similarly,
Azure Pipelines can be used (as was done by a test repo on Azure).
There are also other options of use with PPAs and more---for fullest details see the source of the
shell script run.sh.
