Writing V web applications with veb - the App and Context structs, route attributes with path parameters, ctx.html and ctx.json, templates with $tmpl and $veb.html, middleware with Middleware.use and route_use, shared state with shared and lock, and static…
Create V projects with v new or v init and choose a binary, library or web template.
Manage V packages: install, update, search, remove and link local modules.
V's memory model - GC modes (-gc boehm, -gc none, -prealloc), the optional -ownership checking that catches use-after-move, what unsafe unlocks, and the C interop rules. Use when choosing a GC mode, when a program leaks or grows without bound, when deciding…
V's concurrency primitives - spawn, the sync module (channels, Mutex, RwMutex, WaitGroup, Once, Pool, select), and parallel.amap for parallel map and run. Use when writing code with goroutines, threads, channels, locks, shared mutable state, a WaitGroup, or a…
The V language rules that make code which looks right fail to compile or behave wrongly - ?T versus !T, sum types and match exhaustiveness, mut receivers, module names matching directories, comptime $ forms, and explicit type conversion. Use when writing or…
Using the V MCP server, `v mcp serve`, to read and change V code through the compiler itself - the AST, declarations, references, diagnostics, stdlib docs, an AST-aware rename, a guarded edit and the formatter. Use when an agent needs to know what a V file…
Writing V as a scripting language - `.vsh` script mode, its implicit `import os` and unqualified `os` calls, running a script directly, the executable-cache contract that governs rebuilds, compiling a script without running it, and shebang scripts with no…
