## 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`.
