with-watch

with-watch reruns a delegated command when its inferred or explicit filesystem inputs change.

Install

cargo install with-watch
brew install delinoio/tap/with-watch

Examples

with-watch cp src.txt dest.txt
with-watch ls -l
with-watch --shell 'cat src.txt | grep hello'
with-watch sed -i.bak -e 's/old/new/' config.txt
with-watch exec --input 'src/**/*.rs' -- cargo test -p with-watch

Inference Model

• Passthrough and shell modes use built-in command adapters before falling back to conservative path heuristics.
• Known outputs, inline scripts, patterns, and shell output redirects are filtered out of the watch set.
• Pathless defaults are intentionally narrow: only ls, dir, vdir, du, and find implicitly watch the current directory.
• exec --input remains the explicit escape hatch when a delegated command has no meaningful filesystem inputs or when fallback inference would be ambiguous.
