From a06c0d8115892a74666676b50d4282df9850a119 Mon Sep 17 00:00:00 2001 From: Chris Price Date: Thu, 7 Jun 2012 09:09:14 -0700 Subject: Add support for a 'match' parameter to file_line This commit adds a new parameter called "match" to the file_line resource type, and support for this new parameter to the corresponding ruby provider. This parameter is optional; file_line should work just as before if you do not specify this parameter... so this change should be backwards-compatible. If you do specify the parameter, it is treated as a regular expression that should be used when looking through the file for a line. This allows you to do things like find a line that begins with a certain prefix (e.g., "foo=.*"), and *replace* the existing line with the line you specify in your "line" parameter. Without this capability, if you already had a line "foo=bar" in your file and your "line" parameter was set to "foo=baz", you'd end up with *both* lines in the final file. In many cases this is undesirable. --- lib/puppet/type/file_line.rb | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'lib/puppet/type/file_line.rb') diff --git a/lib/puppet/type/file_line.rb b/lib/puppet/type/file_line.rb index f6fe1d0..6b35902 100644 --- a/lib/puppet/type/file_line.rb +++ b/lib/puppet/type/file_line.rb @@ -32,6 +32,11 @@ Puppet::Type.newtype(:file_line) do desc 'An arbitrary name used as the identity of the resource.' end + newparam(:match) do + desc 'An optional regular expression to run against existing lines in the file;\n' + + 'if a match is found, we replace that line rather than adding a new line.' + end + newparam(:line) do desc 'The line to be appended to the file located by the path parameter.' end @@ -49,5 +54,12 @@ Puppet::Type.newtype(:file_line) do unless self[:line] and self[:path] raise(Puppet::Error, "Both line and path are required attributes") end + + if (self[:match]) + unless Regexp.new(self[:match]).match(self[:line]) + raise(Puppet::Error, "When providing a 'match' parameter, the value must be a regex that matches against the value of your 'line' parameter") + end + end + end end -- cgit v1.2.3
