Debug R Packages

Specify debug messages as special string constants, and control debugging of packages via environment variables.

Unicode Symbols at the R Prompt

A small subset of Unicode symbols, that are useful when building command line applications. They fall back to alternatives on terminals that do not support Unicode. Many symbols were taken from the 'figures' 'npm' package (see < https://github.com/sindresorhus/figures>).

Pretty Print R Code in the Terminal

Replace the standard print method for functions with one that performs syntax highlighting, using ANSI colors, if the terminal supports them.

Load Environment Variables from '.env'

Load configuration from a '.env' file, that is in the current working directory, into environment variables.

Tools for R Package Developers

R-hub v2 uses GitHub Actions to run 'R CMD check' and similar package checks. The 'rhub' package helps you set up R-hub v2 for your R package, and start running checks.

Test Shiny Apps

Please see the 'shinytest' to 'shinytest2' migration guide at < https://rstudio.github.io/shinytest2/articles/z-migration.html>.

Tidy Output from Regular Expression Matching

Wrappers on 'regexpr' and 'gregexpr' to return the match results in tidy data frames.

Search and Query CRAN R Packages

Search CRAN metadata about packages by keyword, popularity, recent activity, package name and more. Uses the 'R-hub' search server, see < https://r-pkg.org> and the CRAN metadata database, that contains information about CRAN packages. Note that this is _not_ a CRAN project.

Parse Data of 'R' Code as an 'XML' Tree

Convert the output of 'utils::getParseData()' to an 'XML' tree, that one can search via 'XPath', and easier to manipulate in general.

Provides Access to Git Repositories

Interface to the 'libgit2' library, which is a pure C implementation of the 'Git' core methods. Provides access to 'Git' repositories to extract data and running some basic 'Git' commands.
