从红宝石色中获取256种颜色 [英] Getting 256 colors out of ruby-ncurses

问题描述

我的终端上有256种出色的颜色(这里的测试脚本)，但是当我使用ncurses时(通过Ruby-ncurses)它将停止工作.打印该页面上给出的转义序列可以很好地工作，但是当我初始化ncurses时，"puts"停止工作，并且无法使用我发现的各种ncurses颜色更改/字符串输出函数中的任何一个来输出颜色.有什么作用?

I've got 256 colors working great in my terminal (test scripts here), but it stops working when I use ncurses (via Ruby-ncurses). Printing the escape sequences given on that page works fine, but when I initialize ncurses 'puts' stops working and I can't output the colors with any of the various ncurses color changing/string output functions I've found. What gives?

推荐答案

njsf:您只是在这里，经过大量修改后，我最终使它工作了.谢谢你的帮助.故事:XTerm(以及rxvt和Eterm)通过转义序列(我所看到的)支持256种颜色，但"tput颜色"将显示为"8"，而ncurses将无法达到它们，因为ncurses的表现很好并尝试通过terminfo进行访问.

njsf: You were partially right here, and after tinkering a lot more I eventually got it to work. Thanks for your help. The story: XTerm (and rxvt, and Eterm) support 256 colors via escape sequences (what I was seeing) but 'tput colors' will say '8' and ncurses won't be able to get at them, because ncurses is playing nice and attempting to access via terminfo.

为任何遭受类似痛苦的人谋福利:

For the benefit of anyone with similar pain:

我发现我需要安装ncurses-term(Ubuntu)软件包来获取/lib/terminfo/x/xterm-256color和其他256色terminfo文件.然后我将TERM设置为xterm-256color，并将行'* customization:-color'添加到我的〜/.Xdefaults中，然后运行'xrdb -merge〜/.Xdefaults'进行加载，从那时起，我便拥有了正确的256色在新的xterms中提供支持.

I found I need to install the ncurses-term (Ubuntu) package to get /lib/terminfo/x/xterm-256color and other 256-color terminfo files. Then I set my TERM to xterm-256color and added the line '*customization: -color' to my ~/.Xdefaults, ran 'xrdb -merge ~/.Xdefaults' to load it, and from then on I have proper 256 color support in new xterms.
