tcell VS color

https://github.com/gdamore/tcell s, err := tcell.NewScreen() // Clear screen s.Clear()

I have used https://github.com/gdamore/tcell/ for github.com/raff/gio-games/arrows (look at game_term.go that is the terminal version, alternative to the gio/graphical version)

Hi im using linux (distro: Fedora 37) and I dont i have problems with installing go modules. When i run the commands in terminal (bash) "go install github.com/gdamore/tcell/v2" it gives me this error: "go: 'go install' requires a version when current directory is not in a module Try 'go install github.com/gdamore/tcell/v2@latest' to install the latest version" So when I run the command: "go install github.com/gdamore/tcell/vs@latest" I get this error: "package github.com/gdamore/tcell/v2 is not a main package". Please someone help.

Hi guys, I have fixed the problem. The problem was as stated: remove terminal behavior like when a key is pressed and held it does not work as needed. For example if I want to move character when user press key the player (character) will move one step then stops then move fast like text curser. The solution is not by using [Console Screen Buffer] the Tcell is enough, But the problem is caused by the way the input is read from the user as u/pekim says in comments it is a "Typical behaviour in most environments (not just Windows)". So to fix this you need to use windows API (w32) and read key using GetAsyncKeyState() that will fix the problem.

There's quite a variety of tui libraries in Go with all kinds of different tradeoffs. Likely you won't find one that does just exactly what you want (paren matching support seems particularly unlikely out of the box, dunno if you'll find something you can plug in). tview and the underlying, lower-level tcell may be useful. I see termbox mentioned a lot here though that looks more like a toolbox for building such things than a solution itself.

There's also tcell

How about some libraries that help with building TUIs?

I'll start with https://github.com/gdamore/tcell

(notcurses is the first in C, and currently best globally. The first in Rust might be tui-rs. The first in Go might be tcell.)

a Snake Game implication in Go using 2d array. https://github.com/twiny/snaky it runs on terminal window using github.com/gdamore/tcell/v2/termbox to render Snake movement.

So i have a cli tool thats outputting some text to the cli stdout, i would like the output to be colored, so i used a library called color (github.com/fatih/color), basically the problem is when i output to stdout its fine but when i do something like ./tool | tee -a file.txt the colors disappear from terminal and also not in the output file, why is that and how do i prevent that ?

printer.go - Handles printing (showing) information to the user. This is where fatih/color is being used, so we can print pretty information with colors.

Note, you also need to handle piping to other programs or sending output to a file. See the logic in https://github.com/fatih/color/blob/master/color.go, https://github.com/mattn/go-colorable and https://github.com/mattn/go-isatty.

The platform I'm using is Windows, and I found that prior to Win10 there was no support for ANSI escape codes in the command line, but I have Win10 and am pretty sure my version is up-to-date enough to have this support. I have also been successfully using Fatih's color package, so I had assumed that the escape codes were working. But they are not working when I do it manually, so fmt.Print("\033[F") does not work.

same person that wrote this module i use all the time. https://github.com/fatih/color ???

I am using github.com/fatih/color as an example because it is a very simple library to test this problem out with.

I would use bytes.Contains instead of string.Contains and I would use github.com/fatih/color for ansi colours rather than re-implienting it yourself. Best not to call log.Fatal in functions other than main - it makes testing hard. Instead they should return an error after their main return value.

What’s the benefit over a well established library such as https://github.com/fatih/color ?
