What is watcher?

watcher is a thin filesystem-events binding whose releases are mostly build work.

The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.

What is webfakes?

A fake web server for tests that keeps closing the gap with the real thing.

webfakes runs a real HTTP server inside R tests so packages can exercise network code without hitting the internet. Its releases follow a consistent logic: find a class of behaviour that only the real internet could reproduce, then implement it locally. HTTPS arrived in 1.4.0; before that the httpbin clone reached full parity with the Python original, and a fake git HTTP server landed alongside CGI middleware. The most recent release, 1.5.0, is about the server's own rough edges — keep-alive timeouts, locale-independent HTTP date parsing, and trailing-slash route matching.

watcher is a thin filesystem-events binding whose releases are mostly build work.

◆ Current state

The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.

◆ Where it's heading

The API is deliberately small and appears finished; the work that remains is making the C dependency install cleanly everywhere. Dropping cmake follows the same move nanonext made, which is not a coincidence — both come from the same author and both are aiming at environments where installing a build system is not an option.

◆ Prediction

With cmake gone and the bundled library current, further releases are most likely to track libfswatch upstream rather than extend the R interface.

A fake web server for tests that keeps closing the gap with the real thing.

◆ Current state

webfakes runs a real HTTP server inside R tests so packages can exercise network code without hitting the internet. Its releases follow a consistent logic: find a class of behaviour that only the real internet could reproduce, then implement it locally. HTTPS arrived in 1.4.0; before that the httpbin clone reached full parity with the Python original, and a fake git HTTP server landed alongside CGI middleware. The most recent release, 1.5.0, is about the server's own rough edges — keep-alive timeouts, locale-independent HTTP date parsing, and trailing-slash route matching.

◆ Where it's heading

The package is converging on being indistinguishable from a real server for test purposes, which is the only way it stays useful — every unsupported protocol feature is a piece of code someone cannot test offline. The remaining work has visibly shifted from missing endpoints to correctness details: date header parsing under unusual locales, keep-alive tuning, request body handling across content types.

◆ Prediction

Expect continued fidelity work against real-server behaviour rather than new app types, with HTTP/2 or authentication schemes the most plausible next gaps given the direction HTTPS opened. The entries do not indicate a specific planned feature.
