I don't have a mac to test on, but I just pushed a commit to the repo and I'd appreciate if someone could go get github.com/cjbassi/gotop, run gotop, and then let me know what happens or what the error messages are this time. Thanks!

cjbassi · 2018-04-09T18:13:16Z

@chlins is a different issue I think, similar to #12.

pbnj · 2018-04-09T18:21:02Z

@cjbassi - I just ran go get github.com/cjbassi/gotop and ran $GOPATH/bin/gotop, but ~~it's completely blank~~ nothing happens.

Also, tried go build and running ./gotop. Same result.

cjbassi · 2018-04-09T19:34:19Z

@petermbenjamin Are you also on OSX? What terminal are you using?

cjbassi · 2018-04-09T19:48:17Z

Also, are these issues on startup? Or when?

pbnj · 2018-04-09T20:21:24Z

@cjbassi:

yes, I'm on macOS Sierra 10.12.6.
Terminal Stack: iTerm + zsh + oh-my-zsh
The issue is at startup from what I can tell. Launching gotop command just hangs.

Update 1: I'm also running inside tmux v2.6

pbnj · 2018-04-09T20:31:52Z

@cjbassi - ok, some updates.

I tried it on Terminal.app (native terminal client on macOS). It took a few minutes (~ 1-2 mins) before gotop displayed the visualizations.

I tried it on iTerm and waited a few minutes to compare. It erred out with the following error message:

Update 1:

Tried on iTerm outside of tmux, still takes about 1-2 mins before it throws error (which seems to be similar to Panic caused by sparkline issue #12):

cjbassi · 2018-04-09T22:03:14Z

@petermbenjamin I appreciate all the troubleshooting you're doing. Looks like the index out of range error is the same one that chlins is getting. I just pushed some changes that include better error logging so it'd help if you could update and build/run from source and see what the errors give you this time.

viktor-evdokimov · 2018-04-10T01:18:16Z

Just checked with the same config as @petermbenjamin but without tmux. It seems to work, only i have light solar theme and text is white on white

cjbassi · 2018-04-10T04:46:08Z

@viktor-evdokimov I think the issue there is that the default colorscheme for gotop has a transparent background which doesn't look great on white colored terminals. You could try one of the other colorschemes by using the -c flag, or if none of those work I could add a colorscheme that better suits white backgrounds.

cjbassi · 2018-04-10T05:36:15Z

@viktor-evdokimov Just added the 'default-dark' colorscheme for brighter backgrounds to the latest release. Let me know if that works or if there's still issues.

cjbassi · 2018-04-11T22:19:06Z

@petermbenjamin the panic you were getting should hopefully be fixed. Can you try the latest version to see what happens this time?

pbnj · 2018-04-11T22:45:17Z

@cjbassi - Indeed.
Tested by running:

$ go get -u -v github.com/cjbassi/gotop
$ gotop

And it doesn't crash or panic.

But, it's still taking about a minute before anything appears on the screen. I am not sure why.

Would you like me to open a separate GH issue for the slow startup time on macOS?
Also, any pointers/directions on troubleshooting/debugging this problem?

cjbassi · 2018-04-11T23:49:37Z

@petermbenjamin Yah I think opening a new issue would be good.

I think the best way to debug the slow startup is to throw a bunch of fmt.Println("1"), fmt.Println("2"), etc into main.go and see where the program hangs for a while. If you're not familiar with Go I could create a branch with the print statements for you to test, just let me know.

pbnj · 2018-04-12T00:01:54Z

I will create a new issue and try to fmt.Println debug it and will let you know what I find.

Also on 10.12.6, clean install via

$ go get -u -v github.com/cjbassi/gotop
$ gotop

and this is the error I'm getting after about 45-60 seconds:

Error caught. Exiting program.

cjbassi · 2018-04-12T02:55:21Z

@heliostatic So the program runs and works for about 45 seconds and then gives that error?

The error is caused by gopsutil which I've already submitted an issue to, but it's good to get more info.

heliostatic · 2018-04-12T03:07:50Z

@cjbassi Good clarification--No, it sits at a blank terminal and then errors out.

rkumar · 2018-04-15T09:41:37Z

Getting this on OSX Sierra on both iTerm and Terminal. Nothing happens for half a minute, then I get this error. Installed using homebrew.

I get the same issue as @rkumar when installing via brew but it works when installing via goget

maxtar · 2018-04-16T08:26:17Z

Have the same issue in Windows:

f1337 · 2018-04-29T00:47:20Z

Worked for me, just now, with a 20-second startup delay (timed with stopwatch).go is installed via homebrew (brew install go). I compiled from source:

go get -u -v github.com/cjbassi/gotop
gotop

My system details:
macOS High Sierra 10.13.4
MacBook Pro (Retina, 15-inch, Mid 2015)
Processor: 2.5 GHz i7
Memory: 16 GB
Terminal: iTerm2 + fish shell + ohmyfish. no tmux.

cjbassi · 2018-04-29T01:55:59Z

Thanks for all the info and sorry people have been having issues. It turns out gopsutil has some issues on OSX which makes gotop unusable on OSX right now. Hoping to fix that in the future, but I also don't have a mac to test on right now so help is appreciated. Going to close this issue and open another one that pools the issues people have been having on OSX.

maxtar · 2018-05-03T06:15:44Z

What about windows?

cjbassi · 2018-05-03T06:29:53Z

@maxtar gotop is untested on windows but feel free to try it and let me know if it works or create an issue if it doesn't. I'd be happy to add support if people want it.

maxtar · 2018-05-03T06:49:06Z

@cjbassi As I mentioned here I've got the same issue. Need I creating new issue fro windows?

cjbassi · 2018-05-03T06:58:30Z

@maxtar Oh sorry, I didn't see that you were having the same issue on windows. But yah actually if you create a new issue for that, that would be great. Thanks.

maxtar · 2018-05-03T07:01:24Z

@cjbassi Created :)

cjbassi · 2018-05-24T21:46:21Z

gotop should be working on OSX now, and you can install using either Git, Homebrew, or from Source as documented in the readme. Let me know if you're still having any issues! Thanks @f1337 for helping get it to work!
