Overview

About

Maintained by Bart TurczynskiCRAN page ↗GitLab ↗Website ↗Issues ↗

A focused implementation of the Public Suffix List (PSL). Bundles a reproducible, pinned PSL snapshot and implements the official prevailing-rule algorithm to answer public-suffix (eTLD) and registrable-domain (eTLD+1) queries. Distinguishes ICANN and PRIVATE rule sections, accepts Unicode and ASCII hostnames via 'punycoder' canonicalization, and supports an explicit, validated offline refresh path. The matcher is compiled with 'cpp11' and requires no external system library. Used as the PSL engine by the 'rurl' package.

Changes in 1.2.1

**Parsing the Public Suffix List is roughly 7x faster.** parse_psl_lines() preallocated its rule columns but then wrote each row through a helper function, which made the columns referenced twice and copied all of them on every rule -- quadratic in the number of rules, defeating the preallocation it was paired with. The writes are now in place. On the bundled list (10,323 rules) read_psl_file() drops from 11.97s to 1.69s with byte-identical output, and the package's own test suite drops from 486s to 201s. No behavior changes (PSLR-ufhllfer).
BugReports points at https://gitlab.com/bart-turczynski/pslr/-/issues, the form R's CRAN incoming check requires for a gitlab.com tracker. GitLab now serves issues as work items: a browser following that link is redirected to /-/work_items, while a signed-out non-browser client gets a 404, on every project on the site (PSLR-cmkufiww).

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("pslr", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("bart-turczynski/pslr")

Development version from bart-turczynski/pslr. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-pslr

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-pslr

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-pslr

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
