Ensure that your documentation is healthy with Doctor! This library contains a mix task which you can run against your project to generate a documentation coverage report. Items which are reported on include: the presence of module docs, which functions do/don't have docs, and which functions do/don't have typespecs. You can generate a .doctor.exs
config file to specify what thresholds are acceptable for your project. If documentation coverage drops below your specified thresholds, the mix doctor
task will return a non zero exit status.
The primary motivation with this tool is to have something simple which can be hooked up into CI to ensure that project documentation standards are respected and upheld.
Available in Hex, the package can be installed
by adding doctor
to your list of dependencies in mix.exs
:
def deps do
[
{:doctor, "~> 0.7.0"}
]
end
Documentation can be found at https://hexdocs.pm/doctor.
Doctor comes with 2 mix tasks. One to run the documentation coverage report, and another to generate a .doctor.exs
config file.
To run the doctor mix task and generate a report run: mix doctor
To generate a .doctor.exs
config file with defaults, run: mix doctor.gen.config
Report created for Doctor itself:
Doctor file found. Loading configuration.
