littler 0.3.11: docopt updates
The twelveth release of littler as a CRAN package is now available, following in the fourteen-ish year history as a package started by Jeff in 2006, and joined by me a few weeks later.
littler is the first command-line interface for R as it predates Rscript. It allows for piping as well for shebang scripting via #!, uses command-line arguments more consistently and still starts faster. It also always loaded the methods package which Rscript only started to do in recent years.
littler lives on Linux and Unix, has its difficulties on macOS due to yet-another-braindeadedness there (who ever thought case-insensitive filesystems as a default where a good idea?) and simply does not exist on Windows (yet – the build system could be extended – see RInside for an existence proof, and volunteers are welcome!). See the FAQ vignette on how to add it to your PATH.
A few examples are highlighted at the Github repo, as well as in the examples vignette.
This release mostly responds to the recent docopt release 0.7.0 which brought a breaking change for quoted arguments. In short, it is for the better because an option --as-cran is now available parsed as opt$as_cran which is easier than the earlier form where we needed to back-tick protect as-cran containing an underscore. We also added a new portmanteau-ish option to roxy.r.
The NEWS file entry is below.

CRANberries provides a comparison to the previous release. Full details for the littler release are provided as usual at the ChangeLog page. The code is available via the GitHub repo, from tarballs and now of course also from its CRAN page and via install.packages("littler"). Binary packages are available directly in Debian as well as soon via Ubuntu binaries at CRAN thanks to the tireless Michael Rutter.
Comments and suggestions are welcome at the GitHub repo.
