Sto imparando l'applicazione di debug Golang in Docker. Ho successo con il dlv connect in shell. Potrei aggiungere il punto di rottura, continuare, dopo … posso fare notare in VSCode, ma aspettare per halting .
Faccio clic su sinistra in function principale, fino a un punto rosso. Quindi fare clic sul button verde, che piace come "play". Programma in corsa contenitore, ma non può fermarsi sulla function principale.
Ho usato VSCode in modo sbagliato? Ho bisogno del tuo aiuto. Grazie.
