From 221277e8522b42bf170fded6ea23dfc526703b07 Mon Sep 17 00:00:00 2001 From: Dan Prince Date: Thu, 29 Aug 2013 12:19:16 -0400 Subject: Update file_line resource to support 'after'. When adding new lines to a file the 'after' option can be useful when you need to insert file lines into the middle of a file. This is particularly helpful when using file_line with sectioned config files. NOTE: the after option only works when adding new lines. If you are updating an existing (matched) line it will simply modify it in place. This assumes it was in the right place to begin with. --- lib/puppet/provider/file_line/ruby.rb | 28 +++++++++++++++++++++++++--- 1 file changed, 25 insertions(+), 3 deletions(-) (limited to 'lib/puppet/provider/file_line') diff --git a/lib/puppet/provider/file_line/ruby.rb b/lib/puppet/provider/file_line/ruby.rb index 3cb9f6e..7ddb39f 100644 --- a/lib/puppet/provider/file_line/ruby.rb +++ b/lib/puppet/provider/file_line/ruby.rb @@ -49,10 +49,32 @@ Puppet::Type.type(:file_line).provide(:ruby) do end def handle_create_without_match - File.open(resource[:path], 'a') do |fh| - fh.puts resource[:line] + + regex = resource[:after] ?
