tdd数据格式
tdd是fmpp自己的一种数据格式，语法类似json,但又与json不同，它更像是json的扩充，还支持如下的格式：
Strings need not be quoted if they doesn't look like a legal boolean or number value, and they don't contain:
* white-space: space, tab, line-break, etc.
* Quotation marks or apostrophe-quote: ", '
* Separator-like chars: comma (,), semicolon (;). Colon (:) is allowed without quoting the string if the string is not a key in a hash.
* Bracket-like chars: (, ), [, ], {, }, <, >
* Equals sign (=)
* Plus sign (+)
Line-break can be used instead of comma (,). That is, in practice, you can omit commas that would be at the end of the lines.
If in a hash the value is missing from a key:value pair, then the value defaults to boolean true.
所以以下两种写法是等同的：
{
"user": "Big Joe",
"tall": true,
"animals": [
{"name": "white mouse", "price": 30},
{"name": "black mouse", "price": 25},
{"name": "green mouse", "price": 150}
]
}
{
user: "Big Joe"
tall
animals: [
{name: "white mouse", price: 30}
{name: "black mouse", price: 25}
{name: "green mouse", price: 150}
]
}
