Module Summary
Functions used to render EEP-48 style documentation for a shell.
Since
Module shell_docs was introduced in
OTP 23.0.
Description
This module can be used to render function and type documentation to be printed in a shell. It can only render EEP-48 documentation of the format application/erlang+html. For more information about this format see Documentation Storage in Erl_Docgen's User's Guide.
Data Types
config() =
#{encoding => unicode | latin1,
columns => integer() >= 1,
ansi => boolean()}
#{encoding => unicode | latin1,
columns => integer() >= 1,
ansi => boolean()}
The configuration of how the documentation should be rendered.
- encoding
- Configure the encoding that should be used by the renderer for graphical details such as bullet-points. By default shell_docs uses the value returned by io:getopts().
- ansi
- Configure whether ansi escape codes should be used to render graphical details such as bold and underscore. By default shell_docs will try to determine if the receiving shell supports ansi escape codes. It is possible to override the automated check by setting the kernel configuration parameter shell_docs_ansi to a boolean() value.
- columns
- Configure how wide the target documentation should be rendered. By default shell_docs used the value returned by io:columns().
