in the terminal after a code change, without having to close and reopen the the terminal for the changes to take effect ?
I know I have to recompile / rerun the program (can this be automated? ), but I also have to reopen the terminal other wise the server won’t serve.
I use this utility to automatically reload my Go web applications https://github.com/codegangsta/gin
I’ve never had the issue of having to reopen my terminal. Sorry I can’t help you there.
Thanks. someone else recommended something called ‘entr’, but I couldn’t quite figure it out.
Assuming you have a working Go environment and
GOPATH/bin is in your
gin is a breeze to install:
go get github.com/codegangsta/gin
Then verify that
gin was installed correctly:
I use go.mod in my Go environment. I tried the above steps and it did not install.
This seems to be more up to date and plenty of *
I have never observed that one needs to close the terminal to get a new compiled artifact running… How are you starting the program?
For most if not all my programs it is enough to just CTRL-C them.
If things went south, I sometimes need to do a
kill -9 from a second terminal or an SSH session even, but that is really rare.
Thanks. lets see if I can install it …
I start the server with ./webserver, then a code change, then stop the server with Ctrl-Z, then 'go build . && ./webserver, and it doesn’t restart.
So I close and reopen the terminal and do ./webserver, and it works.
Is Ctrl-C better and/or different from Ctrl-Z ?
You use windows, I use Linux. Ctrl-Z sends EOF there IIRC.
Windows should support Ctrl-C to actually kill the program as well.
PS: if you use Linux it Mac, then ctrl-Z will actually not stop it kill, but send the program into background. Then of course you need to get it back to foreground or kill it or its parent.
Actually I am on Ubuntu.
I just did Ctrl-C and it stopped the server and I was able to restart it without closing the terminal.
Thanks, but Ctrl-C did what I needed.
