🟢 Быстрая установка нужной версии компилятора Go без замены текущей.

Раз пошло обсуждение о том, как установить Go 1.21 не удаляя старую (и без менеджеров пакетов) — на самом деле все довольно просто:

$ go install golang.org/dl/go1.21.0@latest $ go1.21.0 download
$ go1.21.0 run main.go

Для текущего мастера:

$ go install golang.org/dl/gotip@latest $ gotip download
$ gotip run main.go
Полный список https://pkg.go.dev/golang.org/dl - там есть версии Go до 1.5 включительно.

gotip кстати умный - ему можно скормить бранч через gotip download BRANCHNAME или конкретный CL (PR) через gotip download CL-NUMBER. Номер всегда видно в конкретном ревью - например для https://go-review.googlesource.com/c/tools/+/518376/ комманда будет gotip download 518376.

Вот так легко можно поиграться с фичами Go которые еще находятся в разработке.

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences.
