A validator based on the pegboard::Lesson class cached with this_lesson()
that will provide line reports for fenced divs, links, images, and heading
structure. For details on the type of validators avaliable, see the
pegboard article Validation of Lesson Elements
Arguments
- path
the path to the lesson. Defaults ot the current directory
- headings
If
TRUE, headings will be checked and validated. Currently set toFALSEas we are re-investigating some false positives.- quiet
if
TRUE, no messages will be issued, otherwise progress messages will be issued for each test
Value
a list with the results for each test as described in pegboard::Lesson
Details
Headings
We expect the headings to be semantic and informative. Details of the tests
for headings can be found at pegboard::validate_headings()
Internal Links and Images
Internal links and images should exist and images should have alt text.
Details for these tests can be found at pegboard::validate_links()
Fenced Divs (callout blocks)
Callout Blocks should be one of the expected types. Details for this test
can be found at pegboard::validate_divs()
