- Powerful enough to support all common uses.

- Simple and easy to learn/use.
|

- Minimal code size and external dependencies.
|

- Extensible for custom syntaxes.
|

First all options are registered. After that, elements of command line
|

are extracted using operator++.
|
||||
|

For each element, user can find
|

- if it's an option or an argument
|
||||
- name of the option
|
||||
- index of the option
|
||||
- option value(s), if any
|
||||
|
||||
Sometimes the registered option name is not equal to the encountered
|
||||
one, for example, because name abbreviation is supported. Therefore
|
||||
two option names can be obtained:
|
||||
- the registered one
|
||||
- the one found at the command line
|
||||
|
||||
There are lot of style options, which can be used to tune the command
|
||||
line parsing. In addition, it's possible to install additional parser
|

which will process custom option styles.

/** Standalone parser for config files in ini-line format.
|
||||
The parser is a model of single-pass lvalue iterator, and
|
||||
default constructor creates past-the-end-iterator. The typical usage is:
|
||||
config_file_iterator i(is, ... set of options ...), e;
|
||||
for(; i !=e; ++i) {
|
||||
*i;
|
||||
}
|
||||
|
||||
Syntax conventions:
|
||||
|
||||
- config file can not contain positional options
|
||||
- '#' is comment character: it is ignored together with
|
||||
the rest of the line.
|
||||
- variable assignments are in the form
|
||||
name '=' value.
|
||||
spaces around '=' are trimmed.
|
||||
- Section names are given in brackets.
|
||||
|
||||
The actual option name is constructed by combining current section
|
||||
name and specified option name, with dot between. If section_name
|
||||
already contains dot at the end, new dot is not inserted. For example:
|
||||
@verbatim
|
||||
[gui.accessibility]
|
||||
visual_bell=yes
|
||||
@endverbatim
|
||||
will result in option "gui.accessibility.visual_bell" with value
|
||||
"yes" been returned.

||||

||||

/** The 'eof_iterator' class is useful for constructing forward iterators
|
||||
in cases where iterator extract data from some source and it's easy
|
||||
to detect 'eof' -- i.e. the situation where there's no data. One
|
||||
apparent example is reading lines from a file.
|
||||
|
||||
Implementing such iterators using 'iterator_facade' directly would
|
||||
require to create class with three core operation, a couple of
|
||||
constructors. When using 'eof_iterator', the derived class should define
|
||||
only one method to get new value, plus a couple of constructors.
|
||||
|
||||
The basic idea is that iterator has 'eof' bit. Two iterators are equal
|
||||
only if both have their 'eof' bits set. The 'get' method either obtains
|
||||
the new value or sets the 'eof' bit.
|
||||
|
||||
Specifically, derived class should define:
|
||||
|
||||
1. A default constructor, which creates iterator with 'eof' bit set. The
|
||||
constructor body should call 'found_eof' method defined here.
|
||||
2. Some other constructor. It should initialize some 'data pointer' used
|
||||
in iterator operation and then call 'get'.
|
||||
3. The 'get' method. It should operate this way:
|
||||
- look at some 'data pointer' to see if new element is available;
|
||||
if not, it should call 'found_eof'.
|
||||
- extract new element and store it at location returned by the 'value'
|
||||
method.
|
||||
- advance the data pointer.
|
||||
|
||||
Essentially, the 'get' method has the functionality of both 'increment'
|
||||
and 'dereference'. It's very good for the cases where data extraction
|
||||
implicitly moves data pointer, like for stream operation.
