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
Documentation
- The default search engine is bing, how can I use other search engine?
hors set git remote url -n 2 -a -e "google"
If the network seems blocked, you can try to configure proxy like this:
export http_proxy=http://127.0.0.1:1087;export https_proxy=http://127.0.0.1:1087;
Of course, it should be a valid proxy in your machine.
Hors can be used as a lib, here is an example:
use std::str::FromStr;
use hors::{self, SearchEngine};
let search_engine: SearchEngine = SearchEngine::from_str("bing").unwrap();
let target_links: Vec<String> = hors::search_links(
"how to parse json in rust",
search_engine,
)
.await
.unwrap();
assert_ne!(target_links.len(), 0);
for link in target_links {
assert!(link.contains("stackoverflow.com"));
}
