Collaboration diagram for Help Formatting for Online Help (onlinehelp):

Description

Provides functionality for formatting help text for console and reStructuredText.

This module provides helper functions and classes for formatting text to the console and as reStructuredText through a single interface. The main components of the module are:

gmx::HelpWriterContext provides a single interface that can produce both output formats from the same input strings and API calls. Whenever possible, the output format should be abstracted using this interface, but in some cases code still writes out raw reStructuredText.
rstparser.h provides the functionality to parse reStructuredText such that it can be rewrapped for console output.
helpformat.h provides some general text-processing classes, currently focused on producing aligned tables for console output.
ihelptopic.h, helptopic.h, and helpmanager.h provide classes for managing a hierarchy of help topics and printing out help from this hierarchy.

The formatting syntax for strings accepted by this module is described in Help formatting. The module is currently exposed outside GROMACS only through this formatting syntax, not any API calls.
