Nocter

VS Code language support for Nocter .nct source files.

Nocter is a statically typed, value-centered systems language for building native executables from .nct source files. Learn more at nocter.dev.

Features

• .nct file association and file icon
• TextMate syntax highlighting
• editor language configuration for comments, brackets, indentation, and word selection
• snippets for common Nocter declarations
• compiler-backed language server integration through nocter lsp

The extension does not implement Nocter semantics inside VS Code. Diagnostics, hover, symbols, completion, references, semantic tokens, and future semantic features come from the Nocter compiler through the language server.

Requirements

Install Nocter from nocter.dev before using the language server features.

The extension starts the language server with:

nocter lsp

For this to work, nocter must be available on PATH in the environment where VS Code runs. The Nocter installation may place the real files under a directory such as ~/.nocter/ and expose nocter through a symbolic link or platform equivalent in a PATH directory.

The extension does not inspect ~/.nocter/, NOCTER_HOME, or any compiler directory layout. It only starts nocter lsp.

If nocter is not installed, is not available on PATH, or is not executable, the extension shows a setup error with a link to nocter.dev.

Troubleshooting

Check that VS Code can see the Nocter command:

nocter --version

If the command works in a terminal but the extension still cannot start the language server, restart VS Code after changing PATH.

If the command is missing, install Nocter from nocter.dev or add the directory containing nocter to PATH.
