Development notes

rjson uses earthly to containerize common development tasks.

test

To run a comprehensive test, run:

earthly +test

This will run various sub-tests, against multiple versions of R.

unit tests

To run the unit tests, run:

earthly +unittest

or against a particular version of R, e.g. 4.0.0:

earthly +unittest --R_VERSION=4.0.0

rcheck

To run rcheck, run:

earthly +rcheck

Packaging rjson for cran

To create a source rjson_<version>.tar.gz, run:

earthly +cran

This will output a compressed source archive under output/.

Non-earthly tasks

To run R check with valgrind, in the past I have run:

docker run -v `pwd`:/foo -w /foo -ti -e VALGRIND_OPTS='--leak-check=full --show-reachable=yes' --rm --cap-add SYS_PTRACE rocker/r-devel-ubsan-clang R CMD check --use-valgrind rjson

(This should be moved into the Earthfile to make it easier to run).
