Future Lang — VS Code Extension
Syntax highlighting and snippets for the Future programming language.
Features
- Syntax highlighting — keywords, control flow, namespaces (
ai, http, mqtt, tts, rag, vision, home, memory, schedule, system, device, math, assert), string interpolation {variable}, line comments #, numbers, and booleans
- Code snippets for every language construct (see list below)
- Language configuration —
# comment toggling, bracket matching, auto-close pairs, auto-indent inside if/function/for/… blocks, de-indent on end/else/catch
Quick Example
# Ask AI and print the result
answer = ai.ask("What is the capital of Portugal?")
print "AI says: {answer}"
# HTTP with error handling
try
data = http.get("https://api.example.com/users")
print "Got {data.length} users"
catch err
print "Request failed: {err.message}"
end
