Solved by the many helpful members of the Rust community:
extern crate rustc_serialize;
use rustc_serialize::json::Json;
use std::fs::File;
use std::io::Read;
fn main() {
let mut file = File::open("text.json").unwrap();
let mut data = String::new();
file.read_to_string(&mut data).unwrap();
let json = Json::from_str(&data).unwrap();
println!("{}", json.find_path(&["Address", "Street"]).unwrap());
}
```
4. What if we want to make output code colorized?
```shell
hors "how to parse json in python" -c
```
Here it is:
```python
import json
j = json.loads('{"one" : "1", "two" : "2", "three" : "3"}')
print j['two']
```
5. How to get more than one answers
```shell
hors "set git remote url" -n 2 -a
```
Here it is:
```
- Answer from https://stackoverflow.com/questions/2432764/how-to-change-the-uri-url-for-a-remote-git-repository
You can
git remote set-url origin new.git.url/here
(see git help remote) or you can just edit .git/config and change the URLs there. You're not in any danger of losing history unless you do something very silly (and if you're worried, just make a copy of your repo, since your repo is your history.)
^_^ ==================================================== ^_^
- Answer from https://stackoverflow.com/questions/42830557/git-remote-add-origin-vs-remote-set-url-origin
below is used to a add a new remote:
git remote add origin git@github.com:User/UserRepo.git
below is used to change the url of an existing remote repository:
git remote set-url origin git@github.com:User/UserRepo.git
below will push your code to the master branch of the remote repository defined with origin and -u let you point your current local branch to the remote master branch:
git push -u origin master

6. The default search engine is bing, how can I use other search engine?
```shell
hors "set git remote url" -n 2 -a -e "google"
```
# Customize
`hors` is command line tools, which means that users can easily customize it.
For example, in Linux or MacOS, you can easily customize `hors` by alias. You can add the following lines into `profile`:
```shell
alias hors="hors -c"
```
which will enable `hors` colorize output by default. Let's says that we want to make `hors` output the whole answers, coloring output by default. So we can add the following lines into `profile`:
```shell
alias hors="hors -c -a"
```
