Development Environment

Note

For Ubuntu 20.04 LTS

Packages

Install the following:

sudo locale-gen en_GB.utf8
sudo update-locale en_GB.utf8

Development tools (install vim or an editor of your choosing):

sudo apt install build-essential curl mercurial git vim wget

Note

Do we need to install wget?

Configure git with your email and name:

git config --global user.email "you@example.com"
git config --global user.name "Your Name"

Tip

To remove the a/ and b/ prefixes from the diff output: git config --global diff.noprefix true (for more information, see diff.noprefix)

If you wish to use the scripts from dev-scripts install gawk:

sudo apt install gawk

Tip

If installing on versions earlier than 14.04 use apt-get.

python development:

sudo apt install python3-dev
# pillow
# for ubuntu 14.04
sudo apt install libtiff4-dev

# for ubuntu 15.10 and later including 16.04
sudo apt install libtiff5-dev
sudo apt install libjpeg-dev zlib1g-dev libfreetype6-dev
sudo apt install liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk

# for readline
sudo apt install libncurses5-dev

# if you have issues with setuptools e.g. Requirement.parse('setuptools>=0.8'))
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

Postgres:

sudo apt install postgresql libpq-dev

MySQL (if you plan to develop using MySQL):

sudo apt install mysql-server mysql-client default-libmysqlclient-dev

ODBC (if you plan to develop using odbc):

sudo apt install unixodbc-dev

Redis:

sudo apt install redis-server

python

apt install python3.9-venv

To create a virtualenv:

python3 -m venv venv-for-app
source venv-for-app/bin/activate.fish

bash and zsh

A simple script for directory based environments (if a directory contains a .env file it will automatically be executed when you cd into it):

git clone git://github.com/kennethreitz/autoenv.git ~/.autoenv

# bash
echo 'source ~/.autoenv/activate.sh' >> ~/.bashrc

# for zsh use the 'autoenv' plugin
# vim ~/.zshrc
# plugins=(autoenv autojump git history-substring-search mercurial python tmux virtualenv)

Database

Postgresql

Important

For ubuntu 14.10, replace 9.3 with 9.4. For 16.04, replace 9.3 with 9.5. For 18.04, replace 10.x with the correct version.

Replace /etc/postgresql/9.x/main/pg_hba.conf with misc/9.x/pg_hba.conf:

Replace /etc/postgresql/10.x/main/pg_hba.conf with misc/10.x/pg_hba.conf:

sudo chown postgres:postgres /etc/postgresql/9.x/main/pg_hba.conf
sudo chmod 640 /etc/postgresql/9.x/main/pg_hba.conf

Replace /etc/postgresql/9.3/main/postgresql.conf with misc/9.3/postgresql.conf for 9.3 and misc/9.4/postgresql.conf for 9.4:: and misc/9.5/postgresql.conf for 9.5:: and misc/9.6/postgresql.conf for 9.6:: and misc/10.x/postgresql.conf for 10.x:

sudo chown postgres:postgres /etc/postgresql/9.x/main/postgresql.conf
sudo chmod 644 /etc/postgresql/9.x/main/postgresql.conf

Re-start Postgres:

sudo service postgresql restart

Create a role for your user name (replace patrick with your linux user name):

psql -X -U postgres -c "CREATE ROLE patrick WITH NOSUPERUSER CREATEDB NOCREATEROLE LOGIN;"

# if you get 'ERROR:  must be owner of extension plpgsql', then this will solve it
psql -X -U postgres -c "ALTER ROLE patrick SUPERUSER;"

python

pip

Note

Refer to your company Checklist and replace devpi.yourbiz.co.uk with the name of your devpi server. Do the same for the username and password.

Note

(to myself) Check out the --set-cfg parameter in http://doc.devpi.net/latest/userman/devpi_commands.html It might do the following automatically.

Warning

According to the latest pip documentation (https://pip.pypa.io/en/latest/user_guide.html#configuration), there is a config file at ~/.config/pip/pip.conf. (~/.pip/pip.conf is now a legacy per-user configuration file).

Add the following to the ~/.config/pip/pip.conf file:

[install]
index-url = https://devpi.yourbiz.co.uk/kb/dev/+simple/
trusted-host = devpi.yourbiz.co.uk
[global]
require-virtualenv = True

Tip

trusted-host is copied from my current file.

Tip

require-virtualenv requires a virtual environment when using pip.

Add the following to the ~/.pydistutils.cfg file:

[easy_install]
index_url = https://devpi.yourbiz.co.uk/kb/dev/+simple/

.pypirc

Tip

You won’t be able to Release unless you do this!

Add the following to the ~/.pypirc file:

[distutils]
index-servers =
    dev

[dev]
repository: https://devpi.yourbiz.co.uk/kb/dev/
username: bz
password: 789

Tip

To check the configuration of your package index, you can browse to https://pypi.yourbiz.co.uk/kb/dev/+simple/kb-base/

Tools

These are tools that I like (they are not required to build these projects):

• https://www.pkimber.net/howto/linux/apps/alacritty.html

• https://www.pkimber.net/howto/linux/apps/ack.html

• https://www.pkimber.net/howto/linux/fish.html

• https://www.pkimber.net/howto/linux/apps/tmux.html

And legacy notes on some old tools:

• https://www.pkimber.net/howto/linux/apps/atom.html

Microsoft

To install the Microsoft core fonts (useful for sharing documents):

sudo apt install msttcorefonts

Tip

You’ll need to accept the Microsoft EULA.
