• See Move keywords and types highlighted in appropriate colors.
• As you type, Move keywords will appear as completion suggestions.
• If the opened Move source file is located within a buildable project (a Move.toml file can be found in one of its parent directories), the following advanced features will also be available:
  • compiler diagnostics
  • sui commands line tool(you need install Sui Client CLI locally)
  • sui project template
  • go to definition
  • go to references
  • type on hover
  • inlay hints
  • linter for move file
  • ...

Installation

Note:

1.If you already have installed move-analyzer or aptos-move-analyzer, please disable them before installing sui-move-analyzer, because it may have some conflicts.

2.You need to install SuiCLI refer as https://docs.sui.io/references/cli before install sui-move-analyzer.

How to Install (Must Read)

The sui-move-analyzer Visual Studio Code extension works via two components: the sui-move-analyzer language server and the extension itself. Below are two steps that describe how to install all of them.

1. Installing the sui-move-analyzer language server

sui-move-analyzer language server may be installed in one of two ways:

A. Download the precompiled binaries for the sui-move-analyzer language server(Recommended)

Windows & MacOS & Ubuntu

1.Download the newest binary files for the corresponding platform from sui-move-analyzer-releases-pages.

2.Rename it to sui-move-analyzer or sui-move-analyzer.exe.

3.Make sure sui-move-analyzer/sui-move-analyzer.exe can be found in your PATH environment.

After completing the above steps, restart VSCode.

B. Use Cargo

The sui-move-analyzer language server is a Rust program, so we suggest installing it via cargo. If you haven't installed the Rust toolchain, you can install Rustup, which will install the latest stable Rust toolchain including cargo.

Execute the below command to install sui_move_analyzer

cargo install --git http://github.com/movebit/sui-move-analyzer --branch master sui-move-analyzer

The installation may take some time, often several minutes. After installation, the sui-move-analyzer program is in your cargo binary directory. On macOS and Linux, this directory is usually ~/.cargo/bin. You should make sure this location is in your PATH environment variable via export PATH="$PATH:~/.cargo/bin" .

To confirm that you've installed the language server program successfully, execute sui-move-analyzer --version on the command line. You should see the output sui-move-analyzer version number(1.1.2). If you don't see it, check the troubleshooting section at the end.

After completing the above steps, restart VSCode.

2. Installing the sui-move-analyzer Visual Studio Code extension

1. Open a new window in any Visual Studio Code application version 1.55.2 or greater.
2. Open the command palette (⇧⌘P on macOS, or use the menu item View > Command Palette...) and type Extensions: Install Extensions. This will open a panel named Extensions in the sidebar of your Visual Studio Code window.
3. In the search bar labeled Search Extensions in Marketplace, type sui-move-analyzer. The sui-move-analyzer extension should appear in the list below the search bar. Click Install.
4. Open any file that ends in .move. Or to create a new file, click Select a language, and choose the Move language. As you type, you should see that keywords and types appear in different colors.

After completing the above steps, restart VSCode.

Troubleshooting

Please note: If you don't see the version number, you can refer to the troubleshooting section."

[1] cannot find the sui-move-analyzer program

1) windows

If you are installing this extension on a Windows system and have followed the steps in Section 1.A by running the windows-installer.msi, but executing sui-move-analyzer --version in the command line doesn't find the sui-move-analyzer program, the issue may be that VSCode cannot locate the configured environment variables. You can try the following:

1. Restart VSCode and install the sui-move-analyzer VSCode extension.
2. In the Windows system settings, find the user environment variable PATH. Look for an entry ending with MoveBit\sui-move-analyzer\, and copy it.
3. Open the extension settings for sui-move-analyzer in the VSCode extension store. In the sui-move-analyzer > server:path entry, add the path ending with MoveBit\sui-move-analyzer\ before sui-move-analyzer. The final result may look like: C:\Users\YourUserName\AppData\Local\Apps\MoveBit\sui-move-analyzer\sui-move-analyzer.exe
4. Restart a terminal and try running sui-move-analyzer --version in the command line again.

2) mac & linux

If you see an error message language server executable sui-move-analyzer could not be found in the bottom-right of your Visual Studio Code screen when opening a Move file, it means that the sui-move-analyzer executable could not be found in your PATH. You may try the following:

1. Confirm that invoking sui-move-analyzer --version in a command line terminal prints out sui-move-analyzer version number. If it doesn't, then retry the instructions in [step 1]. If it does successfully print this output, try closing and re-opening the Visual Studio Code application, as it may not have picked up the update to your PATH.
2. If you installed the sui-move-analyzer executable to a different location that is outside of your PATH, then you may have the extension look at this location by using the the Visual Studio Code settings (⌘, on macOS, or use the menu item Code > Preferences > Settings). Search for the sui-move-analyzer.server.path setting, and set it to the location of the sui-move-analyzer language server you installed.
3. If you're using it in MacOS, you may meet the error Macos cannot verify if this app contains malicious software, you need to add support for sui-move-analyzer in the system settings Program Trust.

[2] analyzer not work

A. Need Move.toml

Open a Move source file (a file with a .move file extension) and if the opened Move source file is located within a buildable project (a Move.toml file can be found in one of its parent directories), the following advanced features will be available:

• compiler diagnostics
• go to definition
• go to references
• type on hover
• autocomplete
• outline view
• ...

Therefore, the Move.toml file must be found in the project directory for the plug-in's functionality to take effect.

In addition, if you have already opened the move project before, the installed plug-in will not take effect in time. You need to reopen the vscode window and open the move project code again before the plug-in is activated.

B. Need Build Project with Move.toml

When you first open a project, there will be some dependencies (configured in Move.toml) that need to be downloaded, so you need to run the sui move build command first to build the project. During the build process, the dependencies will be downloaded. Once all the dependencies for the project have been downloaded, sui-move-analyzer can properly parse the dependencies and project source code.

[3] build failed with steps in Section 1.B

If cargo install --git http://github.com/movebit/sui-move-analyzer --branch master sui-move-analyzer run failed, and meet the error info as follows:

error: failed to run custom build command for librocksdb-sys...

--- stderr
thread 'main' panicked at 'Unable to find libclang: "couldn't find any valid shared libraries matching: 
['clang.dll', 'libclang.dll']..."'

It's because it relies on MystenLabs/sui_move_build library, which requires an LLVM environment. You can refer to llvm-project go and install llvm.
