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

# From a clone of this repo (installs `jmove` into ~/.cargo/bin, on PATH):
cargo install --path . --locked

# Latest published version (once jmove is on crates.io — not yet published):
cargo install jmove

Use as a library (the CLI and the engine are separate targets; jmove::core holds indexing/planning/apply, jmove::parser the language frontends):

[dependencies]
jmove = { git = "https://github.com/loki5512344/jmove" }
# or, for a local checkout:  jmove = { path = "../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

# Inside a git repo a tracked file moves via `git mv` (staged, history kept);
# --no-git forces a plain rename
jmove mv src/foo.ts src/bar/foo.ts --no-git

# Move a whole directory: every file relocates, every importer follows
jmove mv src/utils src/helpers

# Moves also warn (never edit) about references the import graph cannot
# see: markdown links, package.json fields, jest.mock strings

# 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

# Feed CI/IDE: SARIF 2.1.0 or Checkstyle XML (never changes stdout/exit code)
jmove check --report build/jmove.sarif

# Auto-repair import problems (unused + missing imports today) — same dry-run/atomic engine
jmove fix --dry-run
jmove fix

# 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 and Java (the open niche) are in — real-world tested on google/guava. fix auto-repairs small breakages on the same dry-run/atomic engine (Java: unused, missing and misordered imports; TS: unused imports), then Python, Go. split (automatic file decomposition) is planned — no tool does it. Full plan: docs/PLAN.md.
