An opinionated command line input parsing tool.
Partially an example for myself on variadic templates and how to call C++ code in C. Partially a way to parse cmd line inputs the way I like to pass in command line inputs.
my_app --command
my_app --command 1
my_app --command 1.5
my_app --command 'something'
my_app -i
my_app -i 2
my_app -i 2.3
my_app -i 'something else'
my_app -i -c -u is equivalent to my_app -icu
my_app -a -b 5 -c 5 is equivalent to my_app -abc 5
This last behavior might be a bit contentious, as there is some sort of implicit sharing of input arguments (both b and c are accepting the input 5) while arguments that don't accept arguments will ignore this (like a above).
my_app command
--help will print a list of all known commands with description text.
cmake -B build .
cmake --build build
If you don't want the example apps, change set(EXAMPLES TRUE) to set(EXAMPLES FALSE) in CMakeLists.txt.
