# glint-ts-mode
Tree-sitter major mode and LSP integration for **Ember Glint** (`.gts` / `.gjs`) files in Emacs.
This package provides:
- `glint-ts-mode` — Tree-sitter major mode derived from `tsx-ts-mode`
- `lsp-glint` — `lsp-mode` client for `glint-language-server`
Designed for **Emacs 30+ only**.
---
## Requirements
- Emacs **30.1+**
- Node.js
- [`glint-language-server`](https://github.com/typed-ember/glint)
- `lsp-mode` 9.0+
---
## Installation
### MELPA
```elisp
M-x package-install RET glint-ts-mode
```
### use-package
```elisp
(use-package glint-ts-mode
:ensure t)
```
Opening a .gts or .gjs file will activate the mode and start LSP automatically.
## Usage
Open a .gts or .gjs file.
- `glint-ts-mode` is enabled automatically
- `glint-language-server` starts via `lsp-mode`
- TypeScript LSP (ts-ls) is disabled for Glint buffers
## Tree-sitter Setup
This package relies on native Tree-sitter support in Emacs 30.
Install required grammars:
```elisp
M-x treesit-install-language-grammar RET tsx
M-x treesit-install-language-grammar RET typescript
```
### Optional: Glimmer grammar
This step is only if you need highlighting for GLimmer templates.
```elisp
M-x treesit-install-language-grammar RET glimmer
```
To make these grammars available:
```elisp
(setq treesit-language-source-alist
'((tsx "https://github.com/tree-sitter/tree-sitter-typescript" "master" "tsx/src")
(typescript "https://github.com/tree-sitter/tree-sitter-typescript" "master" "typescript/src")
(glimmer "https://github.com/alexlafroscia/tree-sitter-glimmer")))
```
More information: https://www.gnu.org/software/emacs/manual/html_node/elisp/Parsing-Program-Source.html
## Customization
### Node memory settings
```elisp
(setq lsp-node-args '("--max-old-space-size=4096"))
```
## Design Notes
- glint-ts-mode derives from tsx-ts-mode
- Tree-sitter highlighting uses the TSX grammar
- Glint is treated as TypeScript at the LSP protocol level
- No legacy tree-sitter-mode support is included
