littler 0.3.23 on CRAN: Mostly Internal Fixes

max-heap image

The twentyfourth release of littler as a CRAN package landed on CRAN just now, following in the now twenty-one year history (!!) as a (initially non-CRAN) 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 began to do in later years.

littler lives on Linux and Unix, has its difficulties on macOS due to some-braindeadedness there (who ever thought case-insensitive filesystems as a default were 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, which comes just two months after the previous 0.3.22 release that brought a few new features, is mostly internal. (The previous release erroneously had 0.3.23 in its blog and social media posts, it really was 0.3.22 and this one now is is 0.3.23.) Mattias Ellert address a nag (when building for a distribution) about one example file with a shebang not have excutable modes. I accommodated the ever-changing interface the C API of R (within about twelve hours of being notified). A few other smaller changes were made as well polishing a script or two or usual, see below for more.

The full change description follows.

Changes in littler version 0.3.23 (2026-04-12)

  • Changes in examples scripts

    • Correct spelling in installGithub.r to lower-case h

    • The r2u.r now recognises ‘resolute’ aka 26.06

    • installRub.r can install (more easily) from r-multiverse

    • A file permission was corrected (Mattias Ellert in #131)

  • Changes in package

    • Update script count and examples in README.md

    • Continuous intgegration scripts received minor updates

    • The C level access to the R API was updated to reflect most recent standards (Dirk in #132)

My CRANberries service provides a comparison to the previous release. Full details for the littler release are provided as usual at the ChangeLog page, and also on the package docs website. 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 (in a day or two) Ubuntu binaries at CRAN thanks to the tireless Michael Rutter. Comments and suggestions are welcome at the GitHub repo.
