From cda30a6ab9b6fa673ead091ab0b130cbc6e75dbc Mon Sep 17 00:00:00 2001 From: Chris Price Date: Wed, 17 Oct 2012 13:27:28 -0700 Subject: Minor tweaks to handling of removing settings This commit makes some minor changes to how we handle removing settings. In particular, it updates all of the line numbers of the various 'section' objects to correspond to the new state of the world based on the removal of a line that appeared before them. Also adds one more test related to setting removal. --- lib/puppet/util/ini_file.rb | 26 +++++++++++++++++++++++--- lib/puppet/util/ini_file/section.rb | 18 +++++++++++++++++- 2 files changed, 40 insertions(+), 4 deletions(-) (limited to 'lib') diff --git a/lib/puppet/util/ini_file.rb b/lib/puppet/util/ini_file.rb index 107924d..52ad32c 100644 --- a/lib/puppet/util/ini_file.rb +++ b/lib/puppet/util/ini_file.rb @@ -45,8 +45,19 @@ module Util def remove_setting(section_name, setting) section = @sections_hash[section_name] if (section.has_existing_setting?(setting)) + # If the setting is found, we have some work to do. + # First, we remove the line from our array of lines: remove_line(section, setting) + + # Then, we need to tell the setting object to remove + # the setting from its state: section.remove_existing_setting(setting) + + # Finally, we need to update all of the start/end line + # numbers for all of the sections *after* the one that + # was modified. + section_index = @section_names.index(section_name) + decrement_section_line_numbers(section_index + 1) end end @@ -61,9 +72,7 @@ module Util fh.puts("\n[#{section.name}]") elsif ! section.end_line.nil?
