jmove

Move source files. Keep every import intact.

jmove is a fast, single-binary CLI that moves/renames source files in a project and rewrites all import statements that reference them — no IDE, no language server, no runtime dependencies. Built for humans and AI agents.

Why

git mv moves the file but breaks every relative import pointing at it. IDE renames fix imports but need an IDE. Existing CLI alternatives either shell out to heavy language servers (bun/ts-morph, Rope, gopls, rust-analyzer) or refuse to preview what they will change.

jmove's answer:

• Dry-run + unified diff — see every change before it hits disk.
• Atomic apply with rollback — imports are rewritten first, the file moves last; any failure restores everything.
• AI-agent mode — --json everywhere, stable error codes, exit codes, and a machine-readable skill doc (docs/SKILL.md).
• Pure Rust, one binary — no external toolchains to install.
• Java support — the package/directory coupling nobody else automates outside IntelliJ.

Install

cargo install jmove

Usage

# Preview what a move would change
jmove mv src/utils/parser.ts src/core/parser.ts --dry-run

# Apply it
jmove mv src/utils/parser.ts src/core/parser.ts

# Java: jmove updates `package`, all `import`s and moves the file
jmove mv src/com/example/utils/Parser.java src/com/example/core/Parser.java

# Find broken imports (exit code 2 if any)
jmove check

# AI-agent workflow
jmove mv src/foo.ts src/bar/foo.ts --dry-run --json
jmove mv src/foo.ts src/bar/foo.ts --json
jmove check --json

See docs/EXAMPLES.md for more, and docs/SKILL.md if you are an AI agent.

Roadmap

TypeScript/JavaScript first, then Java (open niche), Python, Go. split (automatic file decomposition) is planned — no tool does it. Full plan: docs/PLAN.md.
