A better way to do git clone

问题:

This is lazy programmer request. I would like to create a shell script automate the following process:

git clone <remote-repo-url>
cd <cloned-folder>
open <cloned-folder> 

So the idea here is to clone a URL and then immediately cd into the cloned-folder. The trick here is to identify the cloned-folder from the url pattern.

For now we can assume that url structure is in this pattern .../<cloned-folder>.git i.e. the url.

I am wondering if we can actually do with using awk or some tools like that. The part i am stuck is finding a appropriate regex, I guess.

USE CASE: Here the use case is if you clone a url, you want to be in the repofolder as soon as possible. The is the pre-requirement if you want to run any git command like git log or mate . which we do 99% of the time.

Thanks in advance.

bash function to do this (works in zsh also):

function lazyclone {
    url=$1;
    reponame=$(echo $url | awk -F/ '{print $NF}' | sed -e 's/.git$//');
    git clone $url $reponame;
    cd $reponame;
}

The awk command prints the part after the last / (e.g from http://example.com/myrepo.git to myrepo.git). The sed command removes the trailing .git

Usage:

$ pwd
~/
$ lazyclone https://github.com/dbr/tvdb_api.git
tvdb_api
Cloning into 'tvdb_api'...
remote: Counting objects: 1477, done.

Receiving objects: 100% (1477/1477), 268.48 KiB | 202 KiB/s, done.
Resolving deltas: 100% (952/952), done.
$ pwd
~/tvdb_api

With git clone, you can specify the folder to clone to, instead of allowing it to be named automatically.

dir=myclone
git clone git://somerepo "$dir"
cd "$dir"
open "$dir"

An improvement from @dbr's answer:

function lazyclone {
    reponame=${1##*/}
    reponame=${reponame%.git}
    git clone "$1" "$reponame";
    cd "$reponame";
}

With the help of Bash's parameter expansion, we can get rid of awk and sed.

The bash parameter version is quite nice, I went with basename cuz it seemed cleaner

function gclocd {
  # git clone and enter the cloned file
  if [[ -z "$2" ]]; then
    reponame=$(basename "$1" ".git");
  else
    reponame=$2;
  fi
    git clone "$1" "$reponame";
  cd "$reponame";
}

I use short memorable tab-completable function names for a bunch of things like this and put them in my .bashrc as aliases/functions, e.g. gcmmt for git commit -m. lazy may well already be a prefix for things in your shell, which means it's that little bit more to type each time...

Instead of getting directory name from url, we could just cd into the latest created directory. Here is the corresponding shell script:

gclcd() {
    git clone --recursive $* && cd "$(ls -t | head -1)"
}
