Command Line Argument Parsing Libraries Args Parsing Libraries Args Parsing Libs Command Line Args Parsing Libraries

Disclaimer: I might be a bit biased here, because my own library CLIPP is also on this list.

Library	CLI formats	opinions
Argument Aggregator	fixed	convoluted syntax hard to build complex CLIs
Argh!	arbitrary	minimalistic easy to use
argparse	fixed	C Library hard to build complex CLIs
Args	flexible	convoluted syntax hard to build complex CLIs
Argtable	fixed	C Library hard to build complex CLIs CLI defs are hard to read
Boost Program Options	flexible	mature supports config files C++98-era syntax & technical debt
CLI11	fixed	extensive feature set supports config files complex CLI defs are hard to read
CLIPP	arbitrary	relatively nice-looking, DSL-like syntax complex CLIs possible error handling could be better not very frequently updated
cxxopts	fixed	easy to write simple CLIs hard to build complex CLIs
DocOpt	fixed	great readability of CLI def. untyped CLI definition clumsy input querying
getopt	fixed	C Library convoluted syntax
getopt_long	fixed	C Library convoluted syntax
GFlags	fixed	convoluted syntax
TCLAP	flexible	convoluted syntax hard to build complex CLIs
The Lean Mean C++ Option Parser	fixed	truly convoluted syntax hard to build complex CLIs
