Highly Optimized Protocol Buffer Serializers

Pure C++ implementations for reading and writing several common data formats based on Google protocol-buffers. Currently supports 'rexp.proto' for serialized R objects, 'geobuf.proto' for binary geojson, and 'mvt.proto' for vector tiles. This package uses the auto-generated C++ code by protobuf-compiler, hence the entire serialization is optimized at compile time. The 'RProtoBuf' package on the other hand uses the protobuf runtime library to provide a general- purpose toolkit for reading and writing arbitrary protocol-buffer data in R.

A Clean, Whitespace-Sensitive Template Language for Writing HTML

Jade is a high performance template engine heavily influenced by Haml and implemented with JavaScript for node and browsers.

Parsing and Evaluation Tools that Provide More Details than the Default

Parsing and evaluation tools that make it easy to recreate the command line behaviour of R.

Read, Write, and Modify TOML Files

Simple toolkit for working with TOML text. Based on tomledit which allows for modifying TOML while preserving order, comments,and whitespace.

Google's Compact Language Detector 3

Google's Compact Language Detector 3 is a neural network model for language identification and the successor of 'cld2' (available from CRAN). The algorithm is still experimental and takes a novel approach to language detection with different properties and outcomes. It can be useful to combine this with the Bayesian classifier results from 'cld2'. See < https://github.com/google/cld3#readme> for more information.

Server-Side Syntax Highlighting

Prism < https://prismjs.com/> is a lightweight, extensible syntax highlighter, built with modern web standards in mind. This package provides server-side rendering in R using 'V8' such that no JavaScript library is required in the resulting HTML documents. Over 400 languages are supported.

A GraphQL Query Parser

Bindings to the 'libgraphqlparser' C++ library. Parses GraphQL < https://graphql.org> syntax and exports the AST in JSON format.

Bindings to AppArmor and Security Related Linux Tools

Bindings to kernel methods for enforcing security restrictions. AppArmor can apply mandatory access control (MAC) policies on a given task (process) via security profiles with detailed ACL definitions. In addition this package implements bindings for setting process resource limits (rlimit), uid, gid, affinity and priority. The high level R function 'eval.secure' builds on these methods to perform dynamic sandboxing: it evaluates a single R expression within a temporary fork which acts as a sandbox by enforcing fine grained restrictions without affecting the main R process. A portable version of this function is now available in the 'unix' package.

Fast and Simple Badge Generator

Bindings to 'badgen' < https://www.npmjs.com/package/badgen> to generate beautiful 'svg' badges in R without internet access. Images can be converted to 'png' using the 'rsvg' package as shown in examples.

Exploring and Testing the Toolchain and System Libraries

Helper functions that interface with the system utilities to learn about the local build environment. Lets you explore 'make' rules to test the local configuration, or query 'pkg-config' to find compiler flags and libs needed for building packages with external dependencies. Also contains tools to analyze which libraries that a installed R package linked to by inspecting output from 'ldd' in combination with information from your distribution package manager, e.g. 'rpm' or 'dpkg'.
