Overview

About

Maintained by David SchochCRAN page ↗GitHub ↗Website ↗Issues ↗

A wrapper for 'ada-url', a 'WHATWG' compliant and fast URL parser written in modern 'C++'. Also contains auxiliary functions such as a public suffix extractor.

Changes in 0.4.0

Breaking changes

privately registered suffixes (github.io, blogspot.com, s3.amazonaws.com, ...) are now part of the public suffix list lookup (#65). public_suffix() and ada_get_domain() gained an icann_only argument, defaulting to FALSE; pass icann_only = TRUE for the previous behaviour. `` r public_suffix("foo.github.io") # "github.io" (was "io") ada_get_domain("https://foo.github.io/p") # "foo.github.io" ada_get_domain("https://foo.github.io/p", icann_only = TRUE) # "github.io" ``

Other changes

public_suffix() now honours the exception (!) rules of the public suffix list, which were previously stored with their ! prefix and could never match. public_suffix("city.kobe.jp") is now "kobe.jp" rather than "city.kobe.jp", and ada_get_domain() returns a domain instead of "" for hosts under those rules

Show all changes in 0.4.0Hide the rest of the changes in 0.4.0

ada_get_domain() no longer strips a leading www. before looking up the suffix; the result is unchanged for ordinary hosts but www.ck and similar no longer come back as NA
the C++ loops check for a user interrupt, so long vectors can be cancelled with Ctrl-C (#49)
fixed url_decode2() dropping the remainder of a string after a % that is not followed by two hex digits (the escape is now passed through verbatim)
fixed public_suffix() erroring on two or more bare hostnames matching a wildcard rule, e.g. public_suffix(c("a.b.ck", "c.d.ck"))
public_suffix() now accepts full URLs with a path (#54), and returns the same suffix for a URL and its hostname
ada_get_domain() now accepts a bare domain, so it is idempotent (#36); schemeless input with a path is still NA
ada_get_basename() gained the decode argument the other getters have, and no longer appends // for schemes without an authority component
all exported functions now error on non-character input instead of silently returning NA

From NEWS.md in the release

Install

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

install.packages("adaR", 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("gesistsa/adaR")

Development version from gesistsa/adaR. 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-adar

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-adaR

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-adaR

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.
