Jquery terminal text formatting syntax, what am I doing wrong?

Question

I am using the jquery terminal and it is working great. However, for the life of me, I cannot figure out the correct syntax that will format my string.

The example says

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

Ok... So I've tried stuff like this

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

and this

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

and this

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

and several others.

This may be a dumb/easy question, but I'm truly stumped. Could someone tell me what I am doing wrong?

Answer 1

Got the answer from Frédéric Hamidi, I needed to include COLOR and BACKGROUND, they were not optional.
