Program Options, part of the collection of [Boost C++ Libraries](http://github.com/boostorg), allows for definition and acquisition of (name, value) pairs from the user via conventional methods such as command line and config file. It is roughly analogous to getopt_long, but for use with C++.

<para>However, more typical is that boolean values are set by the simple
presence of a switch. This is enabled by &bool_switch; as in <code>
("other-option", bool_switch())</code>. This will cause the value to
default to false and it will become true if the switch is found:</para>

<para>When a boolean does take a parameter, there are several options.
Those that evaluate to true in C++ are: "true", "yes", "on", "1". Those
that evaluate to false in C++ are: "false", "no", "off", "0". In addition,
when reading from a config file, the option name with an equal sign and no
value after it will also evaluate to true.</para>

There were two implementation approaches for multiple option

disadvantage is that we cannot return a reference to

Full Usage Examples
===================
These were run on windows, so some results may show that environment, but
results should be similar on POSIX platforms.
Help
----
To see the help screen, with the available options just pass the --help (or -h)
parameter. The program will then exit.
> example.exe --help
Program Options Example
Usage: example [OPTION]... MASTER-FILE [FILE]...
or example [OPTION] --run-gui
-h [ --help ] display this help message
-v [ --version ] show program version
-c [ --config ] arg config files to parse (always parses default.cfg)
--path arg the execution path to use (imports from
environment if not specified)
--verbosity arg (=INFO) set verbosity: DEBUG, INFO, WARN, ERROR, FATAL
-I [ --include-path ] arg paths to search for include files
--run-gui start the GUI
Version is similar to help (--version or -v).
> example.exe -v
Program Options Example 1.0
Basics
------
Running without any options will get the default values (path is set from the
environment):
> example.exe
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
We can easily override that environment path with a simple option:
> example.exe --path a/b/c;d/e/f
First 75 chars of the system path:
a/b/c;d/e/f
Verbosity: INFO
Include Path:
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
You can use a space or equals sign after long options, also backslashes are
treated literally on windows, on POSIX they need to be escaped.
> example.exe --path=a\b\c\;d\e\\f
First 75 chars of the system path:
a\b\c\;d\e\\f
Verbosity: INFO
Include Path:
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
For short options you can use a space:
> example.exe -I path/to/includes
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
path\to\includes
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
Or you can put the option immediately after it:
> example.exe -Ipath/to/includes
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
path\to\includes
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
The include path (--include-path or -I) option allows for multiple paths to be
specified (both on the command line and in config files) and combined into a
vector for use by the program.
> example.exe --include-path=a/b/c --include-path d/e/f -I g/h/i -Ij/k/l
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
a/b/c
d/e/f
g/h/i
j/k/l
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
There are also the option of flags that do not take parameters and just set a
boolean value to true. In this case, running the gui also causes default values
for the gui to be output to the screen.
> example.exe --run-gui
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
Master-File:
Additional Files:
GUI Enabled: true
GUI Height: 100
GUI Width: 100
Network Address: 127.0.0.1
Network Port: 12345
There are also "positional" options at the end of the command line. The first
one specifies the "master" file the others are additional files.
> example.exe --path=a-path -I an-include master.cpp additional1.cpp additional2.cpp
First 75 chars of the system path:
a-path
Verbosity: INFO
Include Path:
an-include
Master-File: master.cpp
Additional Files:
additional1.cpp
additional2.cpp
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
Environment Variables
---------------------
In addition to the PATH environment variable, it also knows how to read the
EXAMPLE_VERBOSE environmental variable and use that to set the verbosity
option/
> set EXAMPLE_VERBOSE=DEBUG
> example.exe
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: DEBUG
Include Path:
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
However, if the --verboseity flag is also set, it will override the env
variable. This illustrates an important example, the way program_options works,
is that a parser will not override a value that has previously been set by
another parser. Thus the env parser doesn't override the command line parser.
(We will see this again in config files.) Default values are seperate from this
heirarcy, they only apply if no parser has set the value and it is being read.
> set EXAMPLE_VERBOSE=DEBUG
> example.exe --verbosity=WARN
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: WARN
Include Path:
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
(You can unset an environmental variable with an empty set command)
> set EXAMPLE_VERBOSE=
> example.exe
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
Config Files
------------
Config files generally follow the [INI file format]
(https://en.wikipedia.org/wiki/INI_file) with a few exceptions.
Values can be simply added tp options with an equal sign. Here are two include
paths added via the default config file (default.cfg), you can have optional
spaces around the equal sign.
# You can use comments in a config file
include-path=first/default/path
include-path = second/default/path
Results in
> example.exe
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
first/default/path
second/default/path
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 127.0.0.1
Network Port: 12345
Values can also be in sections of the config file. Again, editing default.cfg
include-path=first/default/path
include-path = second/default/path
[network]
ip=1.2.3.4
port=3000
Results in
> example.exe
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: INFO
Include Path:
first/default/path
second/default/path
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 1.2.3.4
Network Port: 3000
This example is also setup to allow multiple config files to be specified on
the command line, which are checked before the default.cfg file is read (but
after the environment and command line parsing). Thus we can set the first.cfg
file to contain the following:
verbosity=ERROR
[network]
ip = 5.6.7.8
Results in:
> example.exe --config first.cfg
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: ERROR
Include Path:
first/default/path
second/default/path
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 5.6.7.8
Network Port: 3000
But since the config files are read after the command line, setting the
verbosity there causes the value in the file to be ignored.
> example.exe --config first.cfg --verbosity=WARN
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: WARN
Include Path:
first/default/path
second/default/path
Master-File:
Additional Files:
GUI Enabled: false
Network Address: 5.6.7.8
Network Port: 3000
The config files are parsed in the order they are received on the command line.
So adding the second.cfg file:
verbosity=FATAL
run-gui=true
[gui]
height=720
width=1280
Results in a combination of all three config files:
> example.exe --config first.cfg --config second.cfg
First 75 chars of the system path:
C:\Program Files (x86)\MSBuild\14.0\bin;C:\Perl\site\bin;C:\Perl\bin;C:\Pro
Verbosity: ERROR
Include Path:
first/default/path
second/default/path
Master-File:
Additional Files:
GUI Enabled: true
GUI Height: 720
GUI Width: 1280
Network Address: 5.6.7.8
Network Port: 3000
Incidently the boolean run-gui option could have been set a number of ways
that all result in the C++ boolean value of true:
run-gui=true
run-gui=on
run-gui=1
run-gui=yes
run-gui=
Since run-gui is an option that was set with the bool_switch type, which
forces its use on the command line without a parameter (i.e. --run-gui instead
of --run-gui=true) it can't be given a "false" option, bool_switch values can
only be turned true. If instead we had a value ("my-switch", po::value<bool>())
that could be set at the command line --my-switch=true or --my-switch=false, or
any of the other types of boolean keywords true: true, on, 1, yes;
false: false, off, 0, no. In a config file this could look like:
my-switch=true
my-switch=on
my-switch=1
my-switch=yes
my-switch=
my-switch=false
my-switch=off
my-switch=0
my-switch=no
