Introduction to Bitbucket

Bitbucket is a source code hosting service. It allows you to store your projects' source code and  share it with others or keep it private. Bitbucket projects can be hosted in either Mercurial or Git revision control systems.
In this example, I will try to explain how to start a project using Mercurial revision control software and Ubuntu.

Sign up to Bitbucket

Create a repository

Install mercurial

Open a terminal

sudo apt-get install mercurial

Add your credentials to your machine

Create the file ~/.hgrc in your home directory with the following contents.

[ui]
username = Name Surname <yourmail@domain.com>

ssh way (Optional)

Open a terminal and generate your ssh key.

ssh-keygen

Install xclp.

sudo apt-get install xclip

Copy ssh key to clipboard.

xclip -sel clip < ~/.ssh/id_rsa.pub

Go to Bitbucket -> Manage account -> SSH keys -> Add key and paste your ssh key.

Clone your empty newproject

hg clone ssh://hg@bitbucket.org/accountname/newproject

Create a file and mark the commit

echo "# This is my README" >> README.md
hg addremove
hg commit -m "First commit. Adding a README."

Push changes

hg push https://accountname@bitbucket.org/accountname/newproject

ssh way (Optional)

hg push ssh://hg@bitbucket.org/accountname/newproject

Ignore files from push

To ignore files from the push, create .hgignore file in your projects root directory, with the following contents.

# use glob syntax.
syntax: glob
.hgignore
private_file.php
*~

In this way, you protect private_file.php, all backup files (ending with ~) and .hgignore file as well.

Strip accidental commits

It is a common mistake to push a commit that contained personal files.
To delete such a commit visit the repository page in Bitbucket.
Go to Commits and copy the commit hash.
Then go to repository Administration -> Strip changesets -> Paste the hash -> Preview and Confirm Strip.
Finally, go to Commits to verify it's removal.

Strip commit locally

To enable strip, add the following lines to ~/.hgrc

[extensions]
hgext.mq =

Then, in a terminal at your projects root directory, enter the following command with the commit_hash you want to remove.

hg strip -r commit_hash
