        --disable_proxy    Disable system proxy.
    -h, --help             Prints help information
    -l, --link             display only the answer link.
    -V, --version          Prints version information

    -e, --engine <engine>                    select middle search engine, currently support `bing`, `google` and
                                             `duckduckgo`. [default: duckduckgo]

Usage example

  1. Want to know how to export pandas dataframe to csv?
hors "pandas dataframe to csv"

Here it is:

- Answer from
df.to_csv(file_name, sep='\t')
  1. If we just want to know where is the answer existed?
hors "pandas dataframe to csv" -l

Here it is:

Title - pandas writing dataframe to csv file
  1. If we want more about the answer detailed?
hors "how to parse json in rust" -a

Here it is:

- Answer from

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());
  1. What if we want to make output code colorized?
hors "how to parse json in python" -c

Here it is:

import json
j = json.loads('{"one" : "1", "two" : "2", "three" : "3"}')
print j['two']
  1. How to get more than one answers
hors "set git remote url" -n 2 -a

Here it is:

- Answer from
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
below is used to a add a new remote:

git remote add origin

below is used to change the url of an existing remote repository:

git remote set-url origin

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

  1. The default search engine is bing, how can I use other search engine?
hors "set git remote url" -n 2 -a -e "google"


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:

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:

alias hors="hors -c -a"

Special thanks

Very thanks for the awesome project and links :)

  • howdoi which inspired hors (Fow now hors is howdoi which implements in rust).
  • stackoverflow helps user solve question about coding.
