不同终端的nCurses行为不同 [英] Different nCurses behaviours with different terminals

问题描述

我使用不同的终端获得两种不同的行为，这是我的代码:

I obtain two different behaviours using different terminals, this is my code:

(use ncurses)

(initscr)
(curs_set 0)
(noecho)
(start_color)

(define win (newwin 20 50 1 1))

(wclear win)

(box win 0 0) 
(for-each (lambda (y) 
    (for-each (lambda (x) 
        (mvwaddch win y x #\. ))
    (iota 49)))
(iota 19))

(wrefresh win)

(wgetch win)

(endwin)

该代码是用Chicken Scheme编写的，但是熟悉nCurses的任何人都可以轻松阅读.我认为我的问题与库无关，因为它是调用C函数的简单包装.

The code is written in Chicken Scheme but it's easily readable by anyone who knows nCurses. I think my problem doesn't concern the library because it's a simple wrapper which calls the C functions.

但是，如果我使用xterm，uxterm或可以通过CTRL-ALT-F1输入的linux终端，则会得到正确的行为(一个框式窗口).

However, I get the correct behaviour (a boxed window) if I use xterm, uxterm or the linux terminal you can enter with CTRL-ALT-F1.

但是，如果我使用gnome-terminal，terminator或sakura等其他终端，我会得到:

But if I use any other terminals like gnome-terminal, terminator or sakura I get this:

我不认为这是库故障，但我可以尝试用C重写示例(我的C有点生锈).

I don't think it's a library fault but I can try to rewrite the example in C (my C is a little rusted).

推荐答案

这听起来好像您的TERM变量设置为 xterm ，这有时会给基于VTE的终端产生问题(gnome终端等).这是一个常见问题解答( 为什么不只是将TERM设置为"xterm"? ).

That sounds as if your TERM variable is set to xterm, which occasionally produces problems for the VTE-based terminals (gnome-terminal, etc). It's an FAQ (Why not just use TERM set to "xterm"?).

这不是错误(无论如何，这都是错误).

It's not a bug (in ncurses, at any rate).

如果您有完整的终端数据库，则将其设置为 vte 即可.

Setting it to vte will work if you have a complete terminal database...
