App::Yath::Command::ps(3)

NAME
App::Yath::Command::ps - Process list for the runner

DESCRIPTION
List all running processes and runner stages.

USAGE
    $ yath [YATH OPTIONS] ps [COMMAND OPTIONS]

  YATH OPTIONS
Developer

--dev-lib
--dev-lib=lib
-D
-D=lib
-Dlib
--no-dev-lib
    Add paths to @INC before loading ANYTHING. This is what you use if you are developing yath or yath plugins to make sure the yath script finds the local code instead of the installed versions of the same code. You can provide an argument (-Dfoo) to provide a custom path, or you can just use -D without and arg to add lib, blib/lib and blib/arch.

    Can be specified multiple times

Environment

--persist-dir ARG
--persist-dir=ARG
--no-persist-dir
    Where to find persistence files.

--persist-file ARG
--persist-file=ARG
--pfile ARG
--pfile=ARG
--no-persist-file
    Where to find the persistence file. The default is /{system-tempdir}/project-yath-persist.json. If no project is specified then it will fall back to the current directory. If the current directory is not writable it will default to /tmp/yath-persist.json which limits you to one persistent runner on your system.

--project ARG
--project=ARG
--project-name ARG
--project-name=ARG
--no-project
    This lets you provide a label for your current project/codebase. This is best used in a .yath.rc file. This is necessary for a persistent runner.

Finder Options

--finder MyFinder
--finder +Test2::Harness::Finder::MyFinder
--no-finder
    Specify what Finder subclass to use when searching for files/processing the file list. Use the "+" prefix to specify a fully qualified namespace, otherwise Test2::Harness::Finder::XXX namespace is assumed.

Help and Debugging

--show-opts
--no-show-opts
    Exit after showing what yath thinks your options mean

--version
-V
--no-version
    Exit after showing a helpful usage message

Plugins

--no-scan-plugins
--no-no-scan-plugins
    Normally yath scans for and loads all App::Yath::Plugin::* modules in order to bring in command-line options they may provide. This flag will disable that. This is useful if you have a naughty plugin that is loading other modules when it should not.

--plugins PLUGIN
--plugins +App::Yath::Plugin::PLUGIN
--plugins PLUGIN=arg1,arg2,...
--plugin PLUGIN
--plugin +App::Yath::Plugin::PLUGIN
--plugin PLUGIN=arg1,arg2,...
-pPLUGIN
--no-plugins
    Load a yath plugin.

--cover-exclude-private
--no-cover-exclude-private
--cover-files
--no-cover-files
    Use Test2::Plugin::Cover to collect coverage data for what files are touched by what tests. Unlike Devel::Cover this has very little performance impact (About 4% difference)

--cover-from path/to/log.jsonl
--cover-from http://example.com/coverage
--cover-from path/to/coverage.jsonl
--no-cover-from
    This can be a test log, a coverage dump (old style json or new jsonl format), or a url to any of the previous. Tests will not be run if the file/url is invalid.

--cover-from-type json
--cover-from-type jsonl
--cover-from-type log
--no-cover-from-type
    File type for coverage source. Usually it can be detected, but when it cannot be you should specify. "json" is old style single-blob coverage data, "jsonl" is the new by-test style, "log" is a logfile from a previous run.

--cover-manager My::Coverage::Manager
--no-cover-manager
    Coverage 'from' manager to use when coverage data does not provide one

--cover-maybe-from path/to/log.jsonl
--cover-maybe-from http://example.com/coverage
--cover-maybe-from path/to/coverage.jsonl
--no-cover-maybe-from
    This can be a test log, a coverage dump (old style json or new jsonl format), or a url to any of the previous. Tests will coninue if even if the coverage file/url is invalid.

--cover-maybe-from-type json
--cover-maybe-from-type jsonl
--cover-maybe-from-type log
--no-cover-maybe-from-type
    Same as "from_type" but for "maybe_from". Defaults to "from_type" if that is specified, otherwise auto-detect

--cover-metrics
--no-cover-metrics
--cover-types ARG
--cover-types=ARG
--cover-type ARG
--cover-type=ARG
--no-cover-types
    NO DESCRIPTION - FIX ME

--no-wrap
--no-no-wrap
    Do not do fancy text-wrapping, let the terminal handle it
