Jquery终端文本格式语法，我做错了什么？

Question

我正在使用jquery terminal，它运行良好。然而，在我的一生中，我无法弄清楚将格式化我的字符串的正确语法。

例子说

echo([string|function], [options]) — display string on terminal — (additionally if you can call this function with a function as argument it will call that function and print the result, this function will be called every time you resize the terminal or browser). There are three options raw — it will allow to display raw html, finalize — which is callback function with one argument the div container and flush — default is true, if it's false it will not print echo text to terminal until you call flush method. 

You can also use basic text formating using syntax as folow: 

[[guib;<COLOR>;<BACKGROUND>]some text] will display some text:

[[ — open formating
u — underline
s — strike
o — overline
i — italic
b — bold
g — glow (using css text-shadow)
; — separator
color — color of text (hex, short hex or html name of the color)
; — separator
color — background color (hex, short hex or html name of the color)
; — separator [optional]
class — class adeed to format span element [optional]
] — end of format specification
text — text that will be formated (most of the time for internal use, when you format text that's wrap in more then one line you'll get full text in data-text attribute)
] — end of formating

好的...所以我尝试过这样的东西

terminal.echo(["s"], myText);

还有这个

terminal.echo("[[s]" + myText + "]");

还有这个

terminal.echo([["s"], myText]);

还有其他几个。

这可能是一个愚蠢/简单的问题，但我真的很难过。谁能告诉我我做错了什么？
