Sphinx Extension to redirect files

Rediraffe

This sphinx extension redirects non-existent pages to working pages. Additionally, a builder is provided to check that deleted/renamed files in your git repo are redirected.

Rediraffe supports the html and dirhtml builders.

Note: Chained redirects will be resolved. For example, if a config has 6 chained redirects, all 6 links will redirect directly to the final link. The end user will never experience more than 1 redirection.

Installation

python -m pip install sphinxext-rediraffe

Usage

Add sphinxext.rediraffe to your extensions list in your conf.py

extensions = [
   sphinxext.rediraffe,
]

To check that deleted/renamed files in your git repo are in your redirects,

  1. Make sure rediraffe_branch and rediraffe_redirects are set in conf.py.
  2. Run the rediraffecheckdiff builder.

Options

These values are placed in the conf.py of your sphinx project.

  • rediraffe_branch

    • Required for rediraffecheckdiff builder. The branch or commit to diff against.
  • rediraffe_redirects

    • Required. A filename or dict containing redirects
  • rediraffe_template

    • Optional. A jinja template to use to render the inserted redirecting files. If not specified, a default template will be used. This template will only be accessed after the html/htmldir builder is finished; Therefore, this file may be generated as part of your build.
    • variables available to rediraffe_template:
      • from_file - the file being redirected as written in rediraffe_redirects.
      • to_file - the destination file that from_file is redirected to as written in rediraffe_redirects.
      • from_url - the path to from_url's html file (built by rediraffe) relative to the outdir.
      • to_url - the path to to_url's built html file relative to the outdir.
      • rel_url - the relative path from from_url to to_url.

Example Config

redirects only (file)

conf.py:

rediraffe_redirects = "redirects.txt"

redirects.txt:

another.rst index.rst
another2.rst another.rst

redirects only (dict)

conf.py:

rediraffe_redirects = {
    "another.rst": "index.rst",
    "another2.rst": "another.rst",
}

redirects + diff checker

conf.py:

rediraffe_redirects = "redirects.txt"
rediraffe_branch = "master~1"

redirects with jinja template

conf.py:

rediraffe_redirects = "redirects.txt"
rediraffe_template = "template.html"

template.html:

<html>
    <body>
        <p>Your destination is {{to_url}}</p>
    </body>
</html>

A complex example can be found at tests/roots/ext/.

Testing

Rediraffe uses pytest for testing. To run tests:

  1. Install this package
  2. Install test dependencies
    python -m pip install -r test-requirements.txt
    
  3. Navigate to the tests directory and run
    python -m pytest --headless
    

The --headless flag ensures that a browser window does not open during browser backed selenium testing.
