Chi Language

Edit Chi projects in VS Code with compiler-backed diagnostics, completions, hover details, go to definition, semantic highlighting, and formatting for both .x and .xs source files.

Chi has two source modes: High Chi (.x) for managed-memory application code and System Chi (.xs) for low-level code with manual ownership. This extension handles both.

Features

• Highlighting for Chi syntax in .x and .xs files
• Compiler diagnostics as you edit
• Completion, including auto-import suggestions
• Hover information and signature help
• Go to definition
• Semantic highlighting
• Document formatting

Requirements

Install Chi before using the language-server features:

curl -fsSL https://chilang.dev/install.sh | sh

If the extension cannot find the Chi standard library, set one of these VS Code settings:

{
  "chiLanguageServer.chiHome": "/path/to/chi"
}

chiLanguageServer.chiHome should point to the installed Chi directory that contains src/stdlib/.

Settings

• chiLanguageServer.chiHome: path to an installed Chi tree.
• chiLanguageServer.maxNumberOfProblems: maximum diagnostics reported per file.
• chiLanguageServer.trace.server: LSP trace level for debugging extension issues.
