This repository is meant to write and manage the Official Documentation of QGIS, a free and Open Source Geographic Information System (GIS) Software, under the Open Source Geospatial (OSGeo) foundation umbrella.

The latest documentation is available at https://docs.qgis.org/latest

Building the documentation

1. If not provided by your OS, you need to install:

   • git (https://git-scm.com/download/)
   • and Python3 (https://www.python.org/downloads/windows/)

   You can install both in default places and with default options.

2. Clone the repository (https://help.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository)

3. Go into that directory and follow the next instructions depending on your OS.

The best way to build the documentation is within a Python Virtual Environment (venv).

Build on Linux

To check/create the venv and use it in the build:

make -f venv.mk html

The venv.mk will create/update a virtual env (if not available) in current dir/venv AND run the html build in it.

You can also use that virtual environment later doing:

source venv/bin/activate

to activate the venv and then run the build from within that venv:

make html

If you want for some reason start from scratch:

make -f venv.mk cleanall

Build PDFs

In Linux, you can also build the PDF versions of the main documents:

make -f venv.mk pdf

For building PDFs you will need to install the XeLaTex compiler package textlive-xetex and GNU Freefont.

sudo apt install textlive-xetex fonts-freefont

Build on macOS or Linux

You can also use your own virtual env by creating it first:

# you NEED python >3.6. Depending on distro either use `python3` or `python`
# common name is 'venv' but call it whatever you like

python3 -m venv venv  # using the venv module, create a venv named 'venv'

Then activate the venv:

source ./venv/bin/activate

With 'activated' virtualenv, you should see 'venv' in the prompt. Install the requirements via the REQUIREMENTS.txt:

pip install -r REQUIREMENTS.txt

And run the build from within that venv:

make html

Want to build your own language? Note that you will use the translations from the po files from git! For example for 'nl' do:

make LANG=nl html

If you want to build PDFs in another language, you can use a similar syntax:

make LANG=fr pdf

For building translated PDFs, you may have to install the texlive extra package for your specific language (e.g. texlive-lang-french). For japanese, it's crucial to install texlive-lang-japanese, which will install the platex compiler. If you plan to build all languages, it might be easier to install all languages packages (texlive-lang-all), but it will use a considerable amount of disk space.

Some languages will also need specific fonts installed:

• Korea (ko) - NanumMyeongjo from the fonts-nanum package
• Hindi (hi) - Nakula from the fonts-nakula package

Build on Windows

Create a virtual environment called 'venv' in that directory (search the Internet for Python Virtual Env on Windows for more details), but in short: use the module 'venv' to create a virtual environment called 'venv'

# in dos box:
python -m venv venv

Then activate the venv:

venv\Scripts\activate.bat

With 'activated' virtualenv, you should see 'venv' in the prompt. Install the requirements via the REQUIREMENTS.txt:

pip install -r REQUIREMENTS.txt

And run the build from within that venv, using the make.bat script with the html argument to locally build the docs:

make.bat html

Want to build your own language? Note that you will use the translations from the po files from git! For example 'nl' do:

set SPHINXOPTS=-D language=nl
make.bat html

Translating

http://www.sphinx-doc.org/en/master/usage/advanced/intl.html

https://pypi.org/project/sphinx-intl/

https://docs.transifex.com/integrations/transifex-github-integration

To update the english po files (which are being used as SOURCE files in transifex):

# FIRST create the pot files in build/gettext (po file be based on those pot files)
make gettext
# then update the english po files only:
sphinx-intl update -p build/gettext -l en

To create the .tx/config to push/pull using tx client do:

# Creating the txconfig is only to be once the first time (we have one now...)
#sphinx-intl create-txconfig
sphinx-intl update-txconfig-resources --transifex-project-name qgis-documentation

# Then (only Transifex admin) can push the po source files to Transifex
tx push -fs --no-interactive (push the source (-f) files forcing (-f) overwriting the ones their without asking (--no-interactive)

To update all po files of all languages (Which we do not use here! This is done by Transifex):

export SPHINXINTL_LANGUAGE=de,nl, ...
# is the same same as
sphinx-intl <command> --language=de --language=nl ...

We created a script to create the transifex yaml files for github-transifex integrations.

BUT we do not do this yet as there were some technical issues...
