Handle Reset Choice Popup

LSP-Metals

LSP-metals is the recommended Sublime LSP extension for Metals, the Scala language server. LSP-metals offers automated Metals installation, easy configuration, Metals-specific commands and many other small features.

"Not now" disables this prompt for 2 minutes.
"Don't show again" disables this prompt forever, use rm -rf .metals/ to re-enable the prompt.
Run lsp toggle server panel in the command palette to watch the build import progress. You can optionally add a key binding for this command.
Behind the scenes, Metals uses Bloop to import sbt builds, but you don't need Bloop installed on your machine to run this step.

Once the import step completes, compilation starts for your open *.scala files.

Once the sources have compiled successfully, you can navigate the codebase with goto definition.

Speeding up import

The "Import build" step can take a long time, especially the first time you run it in a new build. The exact time depends on the complexity of the build and if library dependencies need to be downloaded. For example, this step can take everything from 10 seconds in small cached builds up to 10-15 minutes in large uncached builds.

Consult the Bloop documentation to learn how to speed up build import.

Importing changes

When you change build.sbt or sources under project/, you will be prompted to re-import the build.

Configuration

You can edit the package settings by running LSP-metals Settings in the sublime palette or accessing Preferences > Package Settings > LSP > Servers > LSP-metals.

Java version

The LSP-metals extension by default uses the JAVA_HOME environment variable (via environ). Otherwise, it uses which to locate the java executable.

If no JAVA_HOME is detected you can then open Settings by following the instructions in the displayed error message.

Server version

In order to install the latest snapshot of metals you can explicitly set the snapshot version for server_version. Alternatively, you can also just default to the latest snapshot by setting server_version to latest-snapshot. The same can be done for the latest stable release by setting the value to latest-stable, If no version is set, it defaults to the latest stable release as well.

The new release check in done each time sublime text is started.

Workplace Diagnostic

To see all compilation errors and warnings in the workspace, run the following command Toggle Diagnostics Panel Or use the default mapping super+shift+M / ctr+alt+M

To cycle through the diagnostic use the default mapping Next F4 / Previous shift+F4

Run doctor

To troubleshoot problems with your build workspace, run Doctor run in the command pallet. This command opens a browser window.

All Available Commands

The following commands can be invoked simply via the sublime command palette.

Build Import
Build Connect
compile Cascade
Compile Cancel
Doctor Run
New Scala File: Also available in the side bar context menu.

Show document symbols

Run the Document Symbols command to show a symbol outline for the current file. You can also set a key binding for the lsp_document_symbols command

Formatting on save

If you'd like to have LSP-metals format your file on document save then make sure to add this setting to your Sublime settings, Syntax-specific settings and/or in Project files.

"lsp_format_on_save": true,
...

Organize imports on save

If you'd like to have LSP-metals organize your imports on document save then make sure to add this to your LSP settings.

"lsp_code_actions_on_save":{
  "source.organizeImports": true
},
...

Decoration protocol

This plugin implements the Decoration protocol (only for ST4) which allows showing worksheet evaluations (instead of comments), as well as inferred types and other info as Sublime Phantom.

To enable this feature enable the following LSP-metals settings:

"settings": {
  "metals": {
    ...
    "showInferredType": true,
    "showImplicitArguments": true,
    "showImplicitConversionsAndClasses": true
  }
}

Status Bar

Information about your workspace build like compilation errors count, build status, etc. are displayed by Metals in the sublime status bar.

Troubleshooting

If you have any questions or issues with LSP-metals, please submit an issue in this repository if it is related to the extension.

If the issue is general to Metals, please submit it in the Metals issue repo.

If you have any feature requests, we also have a feature request issue repo.
