    n_workers:int=4, # Number of workers
    force:bool=False, # Ignore cache and build all
    file_glob:str='', # Only process notebooks matching glob (other files are always included)

Process notebooks in path for docs rendering

source

nbdev_readme

def nbdev_readme(
    path:str=None, # Path to notebooks
    chk_time:bool=False, # Only build if out of date
):

Create README.md from readme_nb (index.ipynb by default). Skips if the file doesn’t exist.

nbdev-readme calls “quarto render,” which is explained in the Quarto guide here.

Pandoc’s gfm writer hard-wraps prose at 72 columns by default; -M wrap:preserve keeps each paragraph’s line breaks exactly as authored in the notebook instead.

Only the readme notebook itself is processed (plus non-notebook assets like images), so building the README never executes code from the project’s other notebooks; and if the readme notebook doesn’t exist, the command just returns.

source

nbdev_contributing

def nbdev_contributing(
    path:str=None, # Path to notebooks
    chk_time:bool=False, # Only build if out-of-date
):

Create CONTRIBUTING.md from contributing_nb (defaults to ‘contributing.ipynb’ if present). Skips if the file doesn’t exist.

Quarto’s quarto-nav.js rewrites /index.html links to / for clean URLs, but the regex is unanchored, so on a site’s index page it also mangles the “Other Formats” CommonMark link: index.html.md becomes .md (quarto-dev/quarto-cli#14667). _fix_quarto_nav anchors the regex in the rendered site’s copy of the script. Once quarto fixes it upstream, the pattern no longer matches and this becomes a no-op.

with tempfile.TemporaryDirectory() as d:
    nav = Path(d)/'site_libs/quarto-nav/quarto-nav.js'
    nav.parent.mkdir(parents=True)
    nav.write_text(r'x.replace(/\/index\.html/, "/");')
    _fix_quarto_nav(d)
    test_eq(nav.read_text(), r'x.replace(/\/index\.html(?=[?#]|$)/, "/");')
    _fix_quarto_nav(d)   # idempotent, and a no-op once quarto fixes the regex upstream
    test_eq(nav.read_text(), r'x.replace(/\/index\.html(?=[?#]|$)/, "/");')
