Stack cells

[aspyatkin]

I suppose cells should be stacked when terminal width is not sufficient for 4 cells of each day. Now in my terminal with 90 symbols width the output is a real mess.

Correct, that is a problem. I have not researched how to reliably and portably detect terminal width in go yet. If you have some hints/ideas, let me know.

@schachmat, here's a quick program showing how you can detect terminal width.

You might have to run go get golang.org/x/crypto/ssh/terminal before running if you haven't already got this installed.

package main

import (
    "fmt"
    "golang.org/x/crypto/ssh/terminal"
)

func main() {
    width, _, _ := terminal.GetSize(0)
    fmt.Println("Width:", width)
}

Outputs for me:

Width: 159

@schachmat Take a look at this package - tablewriter

[schachmat]

tablewriter does not seem to support correct connections for the vertical and horizontal lines. Also embedding the date between the „Noon“ and „Evening“ columns can't be done.

Apparently you can elegantly solve the problem using the core package syscall and doing an ioctl — but check the parameters you pass, to truly achieve portability among Windows, Linux and OSX (the last two ones behave differently in this case).

I don't know how compatible the renderings are, but you might be able to accomplish this with TermUI?

The package golang.org/x/crypto/ssh/terminal is deprecated.
It moved to golang.org/x/term instead.

Sample:

package main

import (
	"log/slog"
	"os"

	"golang.org/x/term"
)

func main() {
	ttyFd := int(os.Stdin.Fd())
	if !term.IsTerminal(ttyFd) {
		slog.Default().Error("Current Stdin File Descriptor is no terminal, aborting")
		os.Exit(1)
	}
	width, height, err := term.GetSize(ttyFd)
	if err != nil {
		slog.Default().Error(
			"Unable to get terminal size, aborting.",
			slog.Any("error", err),
		)
		os.Exit(1)
	}

	slog.Default().Info(
		"Detected terminal size.",
		slog.Int("columns", width),
		slog.Int("rows", height),
	)
}

Output inside vim:
