TechScript for Visual Studio Code

The official Visual Studio Code and Open VSX extension for TechScript 2.0.

Provides rich language support, real-time Language Server Protocol (LSP) diagnostics, intelligent code completion, semantic syntax highlighting, colon-based auto-indentation, and canonical snippets.

Features

Semantic Syntax Highlighting: Full grammar support for TechScript v2.0 keywords (is, becomes, constant, to, say, return, repeat, for, while, class), double-quoted interpolated strings ("Hello, {name}!"), and comments (#).
Canonical Snippets: Instant snippets for functions (to), loops (repeat N times:, for item in collection:, while), conditionals (if/else if/else), classes (class), and standard declarations.
Language Server Protocol (LSP): Integrated with techscript-lsp for real-time error checking, hover documentation, symbol navigation, and autocomplete.
Auto-Indentation: Indentation rules enforcing the 4-space block standard following a colon (:).
Format & Lint Integration: Native format-on-save (tsfmt / tsc fmt) and lint-on-save (tslint / tsc lint) capabilities.
One-Click Execution: Integrated command palette actions to run, build, check, and test TechScript files directly from the editor.

Quick Start

Create a new file named hello.txs:

constant app_name is "TechScript"

to greet(user_name):
    say "Hello, {user_name}! Welcome to {app_name}."
    return "done"

names is ["Ada", "Alan", "Linus"]

for person in names:
    greet(person)

repeat 2 times:
    say "TechScript executes natively with zero overhead."
