Array ops: arr << element (push) arr.pop() (pop)

This report is designed as a technical brief for a developer, student, or technical manager who wants to begin learning the V programming language using PDF resources, official documentation, and self-generated learning materials. Date: October 2023 (Updated for relevance) Author: Technical Research Unit Subject: Onboarding developers to the V programming language using portable document format (PDF) resources. 1. Executive Summary The V programming language (often called vlang ) is a statically typed, compiled language designed for simplicity, speed, and maintainability. New learners frequently seek PDF guides for offline study, structured tutorials, or reference manuals. However, as of the current release, there is no official, complete PDF manual maintained by the core V team. Instead, the recommended learning path combines the official online documentation, the V Wiki, community-driven books (exportable to PDF), and self-generated documentation from the V compiler itself. However, as of the current release, there is
Struct: struct Point x int y int
git clone https://github.com/vlang/v-book cd v-book # Install md-to-pdf or use pandoc: pandoc book.md -o v_book.pdf --toc A solid “Getting Started” PDF must include these V-specific concepts:
This report provides a practical roadmap for obtaining, creating, or using PDF-equivalent resources to master V programming fundamentals. | Resource | Official PDF Available? | Recommended Action | |----------|------------------------|---------------------| | vlang.io/docs | No | Use online + convert to PDF via browser print | | V Wiki (GitHub) | No | Clone as Markdown → convert to PDF | | "V Book" (community) | Yes (unofficial) | Download community PDFs with caution | | V compiler help ( v help ) | No | Redirect output to text → convert to PDF |
// Option type example num := int("123") or 0 println("Parsed number: $num")
