Documentation build instructions

Clear Linux* OS documentation is written using reStructuredText and built using Sphinx. Follow the instructions in this README to build the documentation locally for development and testing.

Please make yourself familiar with our contribution guidelines before submitting a contribution.

Clone the documentation repository

Clone the documentation repository to your local machine.

git clone https://github.com/clearlinux/clear-linux-documentation

Requirements

Make sure you have Python 3 installed to start.

The Sphinx documentation provides instructions for installing Sphinx on various platforms.

Use pip3 to install additional Python dependencies listed in the requirements.txt file found in the repository:

pip3 install -r requirements.txt

Run the build

We build our documentation using Sphinx. In the source directory of your local clear-linux-documentation repository, preview changes to the documentation by building the docs in the default language (English) by running make html:

make html

sphinx-build -b html -d _build/doctrees   . _build/html
Running Sphinx v1.8.0
making output directory...
.
.
.
build succeeded, 0 warnings.

The HTML pages are in _build/html.

Build finished. The HTML pages are in _build/html.

Open one of the HTML pages found in source/_build/html in a web browser to view the rendered documentation.

This build will generate several warnings as there are two other optional make commands required to build the full documentation.

1. make py to generate the bundle reference material.
2. make man to generate man page reference material.

To build the documentation exactly as seen on the website, use make man, make py, and make htmlall. This builds both external dependencies and all supported languages.

Use virtualenv

To develop documentation in a virtualenv, use the venv target. The Clear Linux OS documentation make target venv provides a simple development environment that ensures that you have the latest packages and that you manage Python versions separately. Use of the virtualenv requires Python 3.6 or higher. For Windows examples below, use Powershell as an Administrator.

The virtual environment uses the same version of Python that was used to create the virtual environment.

Verify pip is installed. A file path to pip should appear.

On Clear Linux OS and macOS*:

which pip

On Windows* 10 OS:

pip --version

If pip is not installed, install it.

On Clear Linux OS and macOS:

python3 -m pip install --user --upgrade pip

On Windows 10 OS:

py -m pip install --upgrade pip

Install virtualenv

Install virtualenv.

On Clear Linux OS and macOS*:

python3 -m pip install --user virtualenv

On Windows 10 OS:

py -m pip install --user virtualenv

Create the virtualenv and install the required packages:

make venv

Activate the venv.

source venv/bin/activate

Follow Run the build section to start developing documentation.

Remove the venv when finished developing.

deactivate

Additional help

Cleaning up

When testing changes in the documentation, make sure to remove the previous build before building again by running make clean:

make clean

This will completely remove the previous build output, including artifacts from the make venv target when done outside an active venv.

Before running make man, please run make clean-man to clear out any previous attempts.

Convenience script

This bash script (Linux only) includes both make clean and make html. It also starts a simple Python web server that displays a preview of the site at http://localhost:8000 on your local machine.

./checkwork.sh

To stop the web server simply use ctrl-c.
