movefmt is a formatting tool that is based on the Aptos Move compiler.

MoveBit is a security audit company for the Move ecosystem, with a vision to make the Move ecosystem the most secure Web3.

The MoveBit team consists of security leaders in academia and enterprise world, with 10 years of security experience, and is the first blockchain security company to leverage formal verification in the Move ecosystem.

A formatting tool, also known as a pretty-printer, prints the parser's AST of the corresponding language into a beautifully formatted string.

Currently, the community has been discussing the need for a formatting tool for the move language, but due to the fact that implementing a formatting tool is not an easy task, there has not yet been a mature and user-friendly formatting tool for the move language.

Based on this, MoveBit developed a move formatting tool for this purpose. It currently supports the formatting of Move code in Aptos Move projects.

movefmt requires Rust compiler to build. From the root directory, execute the following command.

$ git clone https://github.com/movebit/movefmt.git
$ cd movefmt
$ git checkout develop
$ cargo build

The resulted binary movefmt can be found under the directory target/debug.

Run the following command to install movefmt.

$ cargo install --git https://github.com/movebit/movefmt --branch develop movefmt

On MacOS and Linux, movefmt is typically installed in directory ~/.cargo/bin. Ensure to have this path in your PATH environment variable so movefmt can be executed from any location. This step can be done with the below command.

$ export PATH=~/.cargo/bin:$PATH

If you wish to use this tool independently.

# set env variable to see the log
export MOVEFMT_LOG=movefmt=DEBUG

# get help msg
movefmt -h

# format source file with printing verbose msg
movefmt -v /path/to/your/file_name.move

Alternatively, you can easily use the vscode plugin aptos-move-analyzer by installing it. We have integrated movefmt into it, which allows you to format the current move file with just one right-click. The VScode plugin aptos-move-analyzer is installed on the plugin market page with detailed guidance.
