Mo_tho oa ho kenya

Kode ea Go 1.22+ e nang le gofmt-clean e nang le gofmt-clean e hlophisang e le hore e be joalo ka ha e le'me e phethela 'go vet'. Liphetho li kenyelletsa litlhahlobo tsa pakete e felletseng, ho kenya ka nepo ka litsela tsa mojaro, ho koala liphoso ka fmt.Errorf/%w, ho hlakoloa ka kotloloho, le ho ngola ka kotloloho ka log/slog. Likhetho tse 8 tsa setaele (Production / HTTP server / gRPC / CLI / Concurrent goroutines / Worker pool / Minimal main.go / testify tests). E tšehetsa liphetoho tsohle tsa Go ho tloha ho 1.17 (pre-generics) ho ea ho 1.22 (e ka ba le li-iterators tsa func).

E-ea - mohlala oa HTTP o tloaelehileng kapa oa basebetsi-'moho le eena o theko e boima oa li-token tsa ~ 1,500 ka mokhoa o sa tloaelehang oa Qwen 3 Coder, ka hare ho 2,500 o sa tsejoeng kapa 10,000 o ngotsoeng ka letsatsi. Premium Claude Sonnet / GPT-5 e fumanehang ka ho ngola bakeng sa likarabo tse ngata tsa liphutheloana tse thata. Ha ho hlokahale ho ngola ho etsa tlhahlobo.

Copilot ($ 10-19 / mo) ke IDE e felletseng ea IDE, e kopantsoeng ka kotloloho le khoutu ea hau ea 'nete. Cursor ($ 20 / mo) ke fork e felletseng ea VS Code. Cody (Sourcegraph, $ 9-19 / mo) e nka sehlooho ho tsoa ho repo ea hau. Mochini oa rona ke generator ea ho tšoaea ka marang-rang - ha ho na ho kenya, ha ho na sehlooho sa repo, feela ho hlalosa → ho fumana khoutu e loketseng tlhahiso.

Ee — liphoso li phuthetsoe ka fmt.Errorf("...: %w", err) e le hore basebelisi ba ka etsa errors.Is / errors.As them.

Ee — likhetho tsa sehlooho sa Concurrent le Worker-pool li kenyelletsa sync.WaitGroup e hlakileng, errgroup.Group, ho hlakoloa ka ho latela sehlooho, le bophelo ba sethala se nepahetseng (mothusi o koala, mofuputsi o fihla). `go f()` e ngoe le e ngoe e na le maemo a ho tsoa a hlakileng. Bakeng sa litlhahlobo tse boima tsa li-code tse teng tse sa tsoa etsoa, sebelisa /code/review/ le ho khetheha ho "performance".

Ea — khetha Go 1.22'me moralo o sebelisa mofuta o mocha oa 'for range 10 {... }' oa integer le li-iterators tsa li-range-over-func moo ho leng molemo. Bakeng sa generics (e kenyellelitsoe 1.18) moralo o li ngola ka ho feletseng — caches tsa LRU tsa generic, li-utilities tsa slice, li-type-safe collections.
