Re: [go-nuts] Fscan() eats 1st char in scanning values

In your example, you are repeatedly reading one 'item' from the line. This is the source of the confusion, as this is not how Fscanln works - when you do this, *each* item is the documented 'final item' after which there must be a newline. That is, your data would look more like this: space sep

[go-nuts] Re: Go i18n printer directly in templates?

The x packages parse the .go files and work on the parsed tree of a specified package - so they see only what is visible at the go compiler level, and never see what is in templates that are outside of the go files. Here is a StackOverflow on this topic, which suggests a library that does suppo

I want to second what Ozan has said, use *sftp.Client not sftp.Client, but I want to throw out a couple of words about that. First, the documentation specifically warns against copying Mutex. So you need to be fairly certain that no mutexes are used in a struct before using value semantics. An

Such an issue is what I linked you to earlier in the thread. So I do not think you need to create a new issue - however, in the comments in that issue one of the devs asks for use cases where go work sync is not sufficient, so you might want to reply to that with your example where go work sync

Okay, yeah, got home and tried it out, and go work sync is not doing what I thought it was. I had to do go get github.com/janpfeifer/gonb/gonbui in a to get it to build and run. So yeah, if you want to use a bare go get, you have to do replace directives. Blech. -- You received this message

[go-nuts] Re: `go get` and workspaces (`go.work`)

I don't think you need to run go get there at all - just run go mod tidy, and then when you go build, if it needs something it will get it. If you need to download without building, go mod download will do that. Howard -- You received this message because you are subscribed to the Google Group

Ctrl-\ in a Linux terminal sends the SIGQUIT signal. You can also send this signal with kill. Sending SIGQUIT to a golang application (unless it traps it and changes the behavior) will cause it to print all of its goroutine's stack traces and then exit. Perhaps you could use this to confirm th

On what basis are you using globs ("*lient*", etc) in FindWindow? If I understand correctly, the w32 and w32a packages are just wrapping Windows APIs, so the semantics of the use should match the equivalent use of the windows API. The documentation for FindWindow says "Retrieves a handle to the

One more options to add to Tamás' suggestions - due to Go's interface design, implementing a draw.Image, which is an image.Image with an additional Set(x, y int, c color.Color) method, is sufficient to use draw.Draw for compositing. As such, you can pre-allocate a flat-file with sufficient spa

You would implement the Face interface to have your fonts available to Go's text drawing routines. You can try using basicfont directly, however it is fixedwidth only. But just implementing the interface does not seem that onerous. Have a look at https://github.com/hajimehoshi/bitmapfont for a
