newfunction(:validate_absolute_path, :doc => <<-'ENDHEREDOC') do |args|
|
|
Validate the string represents an absolute path in the filesystem. This function works
|
|
for windows and unix style paths.
|
|
|
|
The following values will pass:
|
|
|
|
$my_path = 'C:/Program Files (x86)/Puppet Labs/Puppet'
|
|
validate_absolute_path($my_path)
|
|
$my_path2 = '/var/lib/puppet'
|
|
validate_absolute_path($my_path2)
|
|
$my_path3 = ['C:/Program Files (x86)/Puppet Labs/Puppet','C:/Program Files/Puppet Labs/Puppet']
|
|
validate_absolute_path($my_path3)
|
|
$my_path4 = ['/var/lib/puppet','/usr/share/puppet']
|
|
validate_absolute_path($my_path4)
|
|
|
|
The following values will fail, causing compilation to abort:
|
|
|
|
validate_absolute_path(true)
|
|
validate_absolute_path('../var/lib/puppet')
|
|
validate_absolute_path('var/lib/puppet')
|
|
validate_absolute_path([ 'var/lib/puppet', '/var/foo' ])
|
|
validate_absolute_path([ '/var/lib/puppet', 'var/foo' ])
|

$undefined = undef
|

validate_absolute_path($undefined)
