LSP-ember for Sublime Text

Description and use

LSP-ember enables Sublime Text to provide LSP features for Ember .gjs/.gts files, matching VS Code’s experience.

Problem

Sublime Text lacked LSP support for Ember’s .gjs/.gts template tag files, causing loss of autocompletion, go-to-definition, and hover features.

Outcome

Developers can now enjoy full LSP-powered code intelligence for Ember’s .gjs/.gts files in Sublime Text, matching the experience of VS Code and other IDEs.

Workflow

• 1. Install Template Tag package to get syntax definitions for .gjs and .gts.
• 2. Clone or symlink LSP-ember into Sublime Text Packages directory. ln -s "$HOME/<path>/LSP-ember" "$HOME/Library/Application Support/Sublime Text/Packages/LSP-ember"
• 3. Ensure Glint packages (@glint/ember-tsc and @glint/tsserver-plugin) are installed and compatible with the TypeScript version used.
• 4. Open an Ember project containing .gjs/.gts files in Sublime Text.
• 5. LSP-ember automatically provides LSP features via Glint.
• 6. Verify autocompletion, go-to-definition, and hover work as expected.
• 7. Report issues or contribute code snippets to improve the package.

Evidence

LSP-ember helps Sublime Text be on par with VS Code and a couple of other IDEs.

Source

The implementation (scaffolded with Claude Code) is rather straightforward, because Glint takes care of the hard parts.
