Co-Authored-By: phlptp <top1@llnl.gov>
update readme and add some IniTests and fix a bug from the tests
add_flag_callback
add a few tests to capture the different paths
fix incorrectly updated CMAKE file, and add some subcommand test for option finding
add disable_flag_override and work out some kinks in the find option functions
add some more tests and fix a few bugs in as<> function for options
Allow general flag types and default values, add shortcut notation for retrieving values
Updates to the readme
update the readme with some documentation
add a few more tests to complete code coverage
update with count strings in flags instead an array of strings for each count
add the '!' shortcut notation. add some checks on the help output
allow the false flag syntax to support --option{false}
add a bool lexical cast to make everything consistent when converting to a bool. Moved a few functions around
make the command line behave like the INI file wrt flags, flag options are allowed to process the value so `--flag=false` actually does the expected thing.
Add functionality similar to click style argument that allow specifying a false flag that when used generates a false result on the flag.
Clang++/LLVM 6.0 complains about this from warning
-Wdelete-non-virtual-dtor which is included when using -Wall.
Both App and FormatterBase already have virtual destructors, so this
was probably just accidentally left out.
This is also a C++ best practice; I have drawn some guidelines from
here: http://www.gotw.ca/publications/mill18.htm
