## About
bsdcontrol.rb provides Ruby bindings for
[libhbsdcontrol](https://git.hardenedbsd.org/hardenedbsd/HardenedBSD/-/tree/hardened/current/master/lib/libhbsdcontrol/).
## Examples
__Features__
The first example prints a list of HardenedBSD features that
can be enabled, disabled or restored to the system default
setting:
``` ruby
#!/usr/bin/env ruby
# Required privileges: user, superuser
require "bsdcontrol"
BSD::Control
.available_features
.each do
print "The ", _1.name, " feature is available", "\n"
end
```
__Enable__
The following example enables the mprotect feature for the emacs binary. When
a feature is enabled for a given file, that setting takes precendence
over the system default. The system default can be restored with
[BSD::Control::Feature#sysdef!](http://0x1eef.github.io/x/bsdcontrol.rb/BSD/Control/Feature.html#sysdef!-instance_method):
``` ruby
#!/usr/bin/env ruby
# Required privileges: superuser
require "bsdcontrol"
BSD::Control
.feature(:mprotect)
.enable!("/usr/local/bin/emacs-29.2")
```
__Status__
There are five recognized statuses: `unknown`, `enabled`, `disabled`,
`sysdef`, and `invalid`. The `sysdef` status indicates that a feature
is configured to use the system default, and it is the most common
status:
``` ruby
#!/usr/bin/env ruby
# Required privileges: superuser
require "bsdcontrol"
BSD::Control
.feature(:mprotect)
.status("/bin/ls") # => :sysdef
```
