This is the engine used by tidyall - read that first to get an overview.

You can call this API from your own program instead of executing "tidyall".


This class offers the following methods:


The regular constructor. Must pass at least plugins and root_dir.

$tidyall->new_from_conf_file( $conf_file, %params )

Takes a conf file path, followed optionally by a set of key/value parameters. Reads parameters out of the conf file and combines them with the passed parameters (the latter take precedence), and calls the regular constructor.

If the conf file or params defines tidyall_class, then that class is constructed instead of "Code::TidyAll".

Constructor parameters

  • plugins

    Specify a hash of plugins, each of which is itself a hash of options. This is equivalent to what would be parsed out of the sections in the configuration file.

  • selected_plugins

    An arrayref of plugins to be used. This overrides the "mode" parameter.

    This is really only useful if you're getting configuration from a config file and want to narrow the set of plugins to be run.

    Note that plugins will still only run on files which match their "select" and "ignore" configuration.

  • cache_model_class

    The cache model class. Defaults to "Code::TidyAll::CacheModel"

  • cache

    The cache instance (e.g. an instance of "Code::TidyAll::Cache" or a "CHI" instance.) An instance of "Code::TidyAll::Cache" is automatically instantiated by default.

  • backup_ttl
  • check_only

    If this is true, then we simply check that files pass validation steps and that tidying them does not change the file. Any changes from tidying are not actually written back to the file.

  • no_cleanup

    A boolean indicating if we should skip cleaning temporary files or not. Defaults to false.

  • inc

    An arrayref of directories to prepend to @INC. This can be set via the command-line as "-I", but you can also set it in a config file.

    This affects both loading and running plugins.

  • data_dir
  • iterations
  • mode
  • no_backups
  • no_cache
  • output_suffix
  • quiet
  • root_dir
  • ignore
  • verbose

    These options are the same as the equivalent "tidyall" command-line options, replacing dashes with underscore (e.g. the "backup-ttl" option becomes "backup_ttl" here).

  • msg_outputter

    This is a subroutine reference that is called whenever a message needs to be printed in some way. The sub receives a "sprintf()" format string followed by one or more parameters. The default sub used simply calls "printf "$format\n", @_" but Test::Code::TidyAll overrides this to use the "Test::Builder->diag" method.

$tidyall->process_paths( $path, ... )

This method iterates through a list of paths, processing all the files it finds. It will descend into subdirectories if "recursive" flag is true. Returns a list of Code::TidyAll::Result objects, one for each file.

$tidyall->process_file( $file )

Process the one file, meaning:

  • Check the cache and return immediately if file has not changed.
  • Apply appropriate matching plugins.
  • Print success or failure result to STDOUT, depending on quiet/verbose settings.
  • Write to the cache if caching is enabled.
  • Return a Code::TidyAll::Result object.

$tidyall->process_source( $source, $path )

Like "process_file", but process the source string instead of a file, and does not read from or write to the cache. You must still pass the relative path from the root as the second argument, so that we know which plugins to apply. Returns a Code::TidyAll::Result object.


Given a relative path from the root, returns a list of Code::TidyAll::Plugin objects that apply to it, or an empty list if no plugins apply.


Returns a list of sorted files that match at least one plugin in configuration.

Code::TidyAll->find_conf_file( $conf_names, $start_dir )

Start in the start_dir and work upwards, looking for a file matching one of the conf_names. Returns the pathname if found or throw an error if not found.
