Prime directives: Privacy, Hackability

SearXNG has two prime directives, privacy-by-design and hackability . The hackability comes in three levels:

• support of search engines
• plugins to alter search behaviour
• hacking SearXNG itself

Note the lack of "world domination" among the directives. SearXNG has no intention of wide mass-adoption, rounded corners, etc. The prime directive "privacy" deserves a separate chapter, as it's quite uncommon unfortunately.

Privacy-by-design

SearXNG was born out of the need for a privacy-respecting search tool which can be extended easily to maximize both, its search and its privacy protecting capabilities.

A few widely used features work differently or turned off by default or not implemented at all as a consequence of privacy-by-design.

If a feature reduces the privacy preserving aspects of searx, it should be switched off by default or should not implemented at all. There are plenty of search engines already providing such features. If a feature reduces the protection of searx, users must be informed about the effect of choosing to enable it. Features that protect privacy but differ from the expectations of the user should also be explained.

Also, if you think that something works weird with searx, it's might be because of the tool you use is designed in a way to interfere with the privacy respect. Submitting a bugreport to the vendor of the tool that misbehaves might be a good feedback to reconsider the disrespect to its customers (e.g. GET vs POST requests in various browsers).

Remember the other prime directive of SearXNG is to be hackable, so if the above privacy concerns do not fancy you, simply fork it.

Happy hacking.

Code

Create good commits!

• Structural split of changes
• Conventional Commits
• Git Commit Good Practice
• some like to use: gitmoji
• not yet active: Semantic PR

In order to submit a patch, please follow the steps below:

• Follow coding conventions.

  • PEP8 standards apply, except the convention of line length
  • Maximum line length is 120 characters

• The cardinal rule for creating good commits is to ensure there is only one logical change per commit / read Structural split of changes

• Check if your code breaks existing tests. If so, update the tests or fix your code.

• If your code can be unit-tested, add unit tests.

• Add yourself to the AUTHORS.rst file.

• Choose meaningful commit messages, read Conventional Commits

  <type>[optional scope]: <description>
  
  [optional body]
  
  [optional footer(s)]

• Create a pull request.

Documentation

The reST sources

has been moved from gh-branch into master (docs).

The documentation is built using Sphinx. So in order to be able to generate the required files, you have to install it on your system. Much easier, use our makefile.

Here is an example which makes a complete rebuild:

$ make docs.clean docs.html
...
The HTML pages are in dist/docs.

live build

docs.clean

It is recommended to assert a complete rebuild before deploying (use docs.clean).

Live build is like WYSIWYG. If you want to edit the documentation, its recommended to use. The Makefile target docs.live builds the docs, opens URL in your favorite browser and rebuilds every time a reST file has been changed.

$ make docs.live
...
The HTML pages are in dist/docs.
... Serving on http://0.0.0.0:8000
... Start watching changes

Live builds are implemented by sphinx-autobuild. Use environment $(SPHINXOPTS) to pass arguments to the sphinx-autobuild command. Except option --host (which is always set to 0.0.0.0) you can pass any argument. E.g to find and use a free port, use:

$ SPHINXOPTS="--port 0" make docs.live
...
... Serving on http://0.0.0.0:50593
...

deploy on github.io

To deploy documentation at github.io <.> use Makefile target make docs.gh-pages, which builds the documentation and runs all the needed git add, commit and push:

$ make docs.clean docs.gh-pages
