# readopt ## Overview This is an option parsing library. The following option formats are recognized: * `-f` * `-fvalue` * `-f value` * `-asdf` (grouped short options) * `-asdfvalue` * `-asdf value` * `--file` * `--file value` * `--file=value` * `-f value1 -f value2 ...` (multiple values are represented in an array) * `-f value1 operand1 -f value2 operand2` (operands intermixed with options) It permutes `argv` to handle multiple values for each option and to assign values to operands. `mdoc(7)` `SYNOPSIS` sections and plaintext usage messages can be generated as well (via `readopt_put_usage`). An example can be found in `test/test.c`. ## Building Build and install the library by either using ``` $ ninja # ninja install ``` or ``` $ make # make install ``` By default, the library will be installed to `/usr/local/lib`, which may not be in your library path. You can change this by modifying the `$prefix` in the `config.ninja` or by overriding the `$(PREFIX)` variable for the `Makefile`.
