Common commands collection

cmd.sh

# 1. Create empty branch and copy file from another branch
#    這種方式複製檔案路徑會跟原本的 repository 一樣, 有點不方便
$ git checkout --orphan <branchname>
$ git rm --cached -r .
$ rm -rf *
$ git add .
$ git ci -m 'comment'
$ git checkout <branch_name> path/to/new/file


# 2. Splite a folder or module to another new branch
$ git subtree split --prefix=<your_folder_or_module> -b <branchname>
# Same with above but more concise
$ git subtree split -P <foldername> -b <branchname>

Just push dist to gh-pages

$ git subtree push --prefix dist origin gh-pages

Publishing gh-pages with Travis-CIThe solution at node

> npm run build-npm
> npm run build-site
> git subtree push --prefix site origin gh-pages
> npm version patch
> npm publish
> git push origin `git subtree split --prefix site master`:gh-pages --force
