Motivation

Quite often, the need arises to do line editing instead of managing an entire file with a template resource. This cookbook supplies various resources that will help you do this.

Limitations

  • The line resources processes the entire target file in memory. Trying to edit large files may fail.

  • The end of line processing was only tested using \n and \r\n. Using other line endings very well may not work.

  • The end of line string used needs to match the actual end of line used in the file \n and \r\n are used as the defaults but if they don't match the actual end of line used in the file the results will be weird.

  • Adding a line implies there is a separator on the previous line. Adding a line differs from appending characters.

  • Lines to be added should not contain EOL characters. The providers do not do multiline regex checks.

  • Missing file processing is the way it is by intention

    • add_to_list do nothing, list not found so there is nothing to add to.
    • append_if_no_line create file, add the line.
    • delete_from_list do nothing, the list was not found which implies there is nothing to delete
    • delete_lines do nothing, the line isn't there which implies there is nothing to delete
    • replace_or_add create file, add the line
    • filter_lines create file if the file changes
  • Chef client version 13 or greater is expected.
