## About
hbsdctl.rb is a C extension that binds libhbsdcontrol from the
[hardenedbsd](https://hardenedbsd.org) project to Ruby. Through
this library, you can query what features are available and if
root: enable, disable or query the status of a feature for a
given file.
## Examples
__Features__
As a regular user account, you can obtain a list of available features:
``` ruby
#!/usr/bin/env ruby
# As a regular user account
require "hbsdctl"
BSD::Control
.available_features
.each do
print "The ", _1.name, " feature is available", "\n"
end
```
__Enable__
As a superuser account, you can enable or disable a feature for a given file.
The example enables the mprotect feature for the emacs binary:
``` ruby
#!/usr/bin/env ruby
# As a superuser account
require "hbsdctl"
BSD::Control
.feature(:mprotect)
.enable!("/usr/local/bin/emacs-29.2")
```
__Status__
As a superuser account, you can query whether or not a feature is enabled or disabled
for a given file. There are four statuses that can be returned: `conflict`, `sysdef`,
`enabled`, and `disabled`. The first status (conflict) is rare and indicates that a
feature is both enabled and disabled. The other three are more common. The `sysdef`
status indicates that a feature takes its settings from the system default (sysctl):
``` ruby
#!/usr/bin/env ruby
# As a superuser account
require "hbsdctl"
BSD::Control
.feature(:mprotect)
.status("/bin/ls") # => :sysdef
```
