我需要帮助了解着色如何适用于urwid

color_palette = [
    ('banner', '', '', '', '#fff', 'g35'),
    ('streak', 'white', '', '', 'g0', 'g35'),
    ('inside', '', '', '', 'g0', 'g35'),
    ('outside', '', '', '', 'g0', 'g35'),
    ('bg', '', '', '', 'g35', '#fff'),]

从文档中: http://urwid.org/manual/displayattributes.html#id6

我想使用的颜色:

 - #195c60
 - #193638
 - #232323

用法:http://urwid.org/tutorial/index.html#high-color-modes

import urwid

def exit_on_q(key):
    if key in ('q', 'Q'):
        raise urwid.ExitMainLoop()

palette = [
    ('banner', '', '', '', '#ffa', '#60d'),
    ('streak', '', '', '', 'g50', '#60a'),
    ('inside', '', '', '', 'g38', '#808'),
    ('outside', '', '', '', 'g27', '#a06'),
    ('bg', '', '', '', 'g7', '#d06'),]

placeholder = urwid.SolidFill()
loop = urwid.MainLoop(placeholder, palette, unhandled_input=exit_on_q)
loop.screen.set_terminal_properties(colors=256)
loop.widget = urwid.AttrMap(placeholder, 'bg')
loop.widget.original_widget = urwid.Filler(urwid.Pile([]))

div = urwid.Divider()
outside = urwid.AttrMap(div, 'outside')
inside = urwid.AttrMap(div, 'inside')
txt = urwid.Text(('banner', u" Hello World "), align='center')
streak = urwid.AttrMap(txt, 'streak')
pile = loop.widget.base_widget # .base_widget skips the decorations
for item in [outside, inside, streak, inside, outside]:
    pile.contents.append((item, pile.options()))

loop.run()

听起来您想要使用自定义颜色的urwid高色示例。<​​/ p>

在本教程的示例中,以下行告诉终端使用8位终端颜色模式(https://en.wikipedia.org/wiki/8-bit_color):

$ colortrans 195c60
RGB 195c60 -> xterm color approx 23 (005f5f)
$ colortrans 193638
RGB 193638 -> xterm color approx 23 (005f5f)
$ colortrans 232323
RGB 232323 -> xterm color approx 16 (000000)

要使用自定义颜色,您需要将(可能是RGB)颜色转换为最接近的相应8位终端颜色。请注意,您不一定能够获得完全匹配: way 比8位终端颜色代码更多RGB十六进制颜色代码。

我使用此工具查找颜色的近似匹配项:https://gist.github.com/MicahElliott/719710

palette = [
    ('color1', '', '', '', 'h23', 'h23'),
    ('color2', '', '', '', 'h16', 'h16'),]

使用现代urwid,您可以执行以下操作:

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'html');
app.engine('html', require('ejs').renderFile);

var router = express.Router();    

//This Works
router.get('/', function(req, res, next) {
  res.render('index');
});

//This Works
router.get('/about', function(req, res, next) {
  res.render('about');
});

//This Does NOT Work, How do I get this to work?
router.get('/partials/navbar', function(req, res, next) {
  res.render('/partials/navbar');
});
