galaxy.tool_util.parser package

Package responsible for parsing tools from files/abstract tool sources.

galaxy.tool_util.parser.get_input_source(content)

Wrap dicts or XML elements as InputSource if needed.

If the supplied content is already an InputSource object, it is simply returned. This allow Galaxy to uniformly consume using the tool input source interface.

galaxy.tool_util.parser.get_tool_source(config_file=None, xml_tree=None, enable_beta_formats=True, tool_location_fetcher=None, macro_paths=None, tool_source_class=None, raw_tool_source=None) → ToolSource

Return a ToolSource object corresponding to supplied source.

The supplied source may be specified as a file path (using the config_file parameter) or as an XML object loaded with load_tool_with_refereces.

Bases: object

These determine stdio-based error levels from matching on regular expressions and exit codes. They are meant to be used comparatively, such as showing that warning < fatal. This is really meant to just be an enum.

NO_ERROR = 0

LOG = 1

QC = 1.1

WARNING = 2

FATAL = 3

FATAL_OOM = 4

MAX = 4

descs = {0: 'No error', 1: 'Log', 1.1: 'QC', 2: 'Warning', 3: 'Fatal error', 4: 'Out of memory error'}

A short description of these two styles can be found at https://github.com/galaxyproject/galaxy/pull/4437.

• the oom_exit_code if given and detect_errors is exit_code

• exit codes and regexes from the stdio tag these are prepended to the list, i.e. are evaluated prior to regexes and exit codes derived from the properties of the command tag. thus more specific regexes of the same or more severe error level are triggered first.
