要获得下图,请使用:
curl -s https://gist.githubusercontent.com/HaleTom/89ffe32783f89f403bba96bd7bcd1263/raw/ | bash
该要点bash
/ zsh
代码是shellcheck
干净的,并且还支持“妈妈快看,没有子进程!”。
另外,为了快速bash
:
for i in {0..255} ; do
printf "\x1b[48;5;%sm%3d\e[0m " "$i" "$i"
if (( i == 15 )) || (( i > 15 )) && (( (i-15) % 6 == 0 )); then
printf "\n";
fi
done
对于总矫枉过正,该地段的鼻祖是terminal-colors
,一个572行的脚本有多种输出格式。
您还可以打印真彩色(24位)测试图案。
terminal-colors
,请做curl -s https://raw.githubusercontent.com/eikenb/terminal-colors/master/terminal-colors | python
terminal-colors
,它与我建议的选项相比如何?
我在 Justin Abrahms的GitHub上找到了一个不错的Python脚本,该脚本还打印了颜色的十六进制代码。
将脚本下载到当前工作目录
wget https://gist.githubusercontent.com/justinabrahms/1047767/raw/a79218b6ca8c1c04856968d2d202510a4f7ec215/colortest.py
赋予它执行权限
chmod +x colortest.py
运行:
./colortest.py
这是完整的脚本,以防出现链接腐烂:
#!/usr/bin/env python
# Ported to Python from http://www.vim.org/scripts/script.php?script_id=1349
print "Color indexes should be drawn in bold text of the same color."
print
colored = [0] + [0x5f + 40 * n for n in range(0, 5)]
colored_palette = [
"%02x/%02x/%02x" % (r, g, b)
for r in colored
for g in colored
for b in colored
]
grayscale = [0x08 + 10 * n for n in range(0, 24)]
grayscale_palette = [
"%02x/%02x/%02x" % (a, a, a)
for a in grayscale
]
normal = "\033[38;5;%sm"
bold = "\033[1;38;5;%sm"
reset = "\033[0m"
for (i, color) in enumerate(colored_palette + grayscale_palette, 16):
index = (bold + "%4s" + reset) % (i, str(i) + ':')
hex = (normal + "%s" + reset) % (i, color)
newline = '\n' if i % 6 == 3 else ''
print index, hex, newline,
虽然不是完全 “测试模式”,但我有xterm-color-chooser:
curl -s https://raw.githubusercontent.com/grawity/code/master/term/xterm-color-chooser | python3
我编写的另一个脚本位于VTE存储库中:https : //git.gnome.org/browse/vte/plain/perf/256test.sh? h = vte-0-38 。
它需要一个120列或更多列的窗口,但是可以很好地紧凑地排列6x6x6立方体的颜色。为了紧凑起见,删除了索引的前几位,您可以轻松地找出它们。竖线使您能够检查前景色的精确RGB,而不会出现抗锯齿现象(就像数字一样)。
输出的顶部(下面的屏幕快照中未显示)展示了粗体与明亮模糊性之间的疯狂关系,即,将粗体转义序列与用于前景的传统8种颜色的转义序列之一组合也切换为明亮的对应色,而使用新样式(支持256色)的转义序列不再如此,甚至对于前8种颜色也是如此。至少这就是xterm和VTE(GNOME终端等)的行为方式。
此屏幕快照显示了大约一半的输出:
curl -s -L https://git.gnome.org/browse/vte/plain/perf/256test.sh?h=vte-0-38 | bash
也许是多余的,但我编写了一个版本,该版本使用自动外壳宽度检测功能在背景上打印256种颜色,因此颜色更容易看到。
