Mica for Visual Studio Code

Language support for the Mica programming language: syntax highlighting, editor behaviour, and — with the Mica compiler installed — diagnostics, go to definition, hover, and the document outline.

Mica is a statically typed systems language that compiles to native Linux x86-64 and AArch64 binaries. This extension teaches Visual Studio Code to read and work with .mica files.

Features

• Syntax highlighting for the complete current language: keywords and contextual words, built-in and parameterized types, nested comments, string and regular-expression literals, and numerals with masks and digit separators.
• Editor behaviour: begin/end as a bracket pair, code folding, automatic indentation, and word selection that understands 0x, 0b, and 1_000_000.
• Diagnostics — compile errors and warnings appear in the editor when a file opens and on every save, at the exact positions the compiler reports.
• Go to definition — jump from a name to its declaration.
• Hover — the resolved signature of the symbol under the cursor.
• Document outline — the functions, types, and constants a file declares, in the Outline view and the breadcrumb bar.

The language features are provided by the Mica compiler itself running as a language server, so what the editor underlines is exactly what the build would report.

Requirements

• Syntax highlighting and editor behaviour work out of the box — no additional software.
• The language features (diagnostics, definition, hover, outline) require the Mica compiler, version 6.12.4 or newer, available from mica-dev.com/learn/install. The extension finds it as mica on PATH; a different location can be set with mica.languageServer.path. Without the compiler, the extension simply stays with highlighting and shows a single notice.
