void ProgramBase::add_option | ( | const string & | option, |
const string & | parm_name, | ||
int | index_group, | ||
const string & | description, | ||
OptionDispatchFunction | option_function, | ||
bool * | bool_var = (bool *)NULL , |
||
void * | option_data = (void *)NULL |
||
) | [protected, inherited] |
Adds (or redefines) a command line option.
This is another variant on add_option(), above, except that it receives a pointer to a "method", which is really just another static (or global) function, whose first parameter is a ProgramBase *.
When parse_command_line() is executed it will look for these options (followed by a hyphen) on the command line; when a particular option is found it will call the indicated option_function, supplying the provided option_data. This allows the user to define a function that does some special behavior for any given option, or to use any of a number of generic pre-defined functions to fill in data for each option.
Each option may or may not take a parameter. If parm_name is nonempty, it is assumed that the option does take a parameter (and parm_name contains the name that will be printed by show_options()). This parameter will be supplied as the second parameter to the dispatch function. If parm_name is empty, it is assumed that the option does not take a parameter. There is no provision for optional parameters.
The options are listed first in order by their index_group number, and then in the order that add_option() was called. This provides a mechanism for listing the options defined in derived classes before those of the base classes.
We can't easily add a variant that accepts a real method, because the C++ syntax for methods requires us to know exactly what class object the method is defined for, and we want to support adding pointers for methods that are defined in other classes. So we have this hacky thing, which requires the "method" to be declared static, and receive its this pointer explicitly, as the first argument.

Word-wraps the indicated text to the indicated output stream.
The first line is prefixed with the indicated prefix, then tabbed over to indent_width where the text actually begins. A newline is inserted at or before column line_width. Each subsequent line begins with indent_width spaces.
An embedded newline character ('
') forces a line break, while an embedded carriage-return character (''), or two or more consecutive newlines, marks a paragraph break, which is usually printed as a blank line. Redundant newline and carriage-return characters are generally ignored.
The flag last_newline should be initialized to false for the first call to format_text, and then preserved for future calls; it tracks the state of trailing newline characters between calls so we can correctly identify doubled newlines.
