galaxy.tool_util.lint module

This modules contains the functions that drive the tool linting framework.

LintContext: a container for LintMessages LintMessage: the actual message and level

The idea is to define a LintContext and to apply a linting function foo on a target. The level (defined by LintLevel) determines which linting messages are shown:

lint_ctx = LintContext(level) # level is the reporting level
lint_ctx.lint(..., lint_func = foo, lint_target = target, ...)

The lint function essentially calls foo(target, self). Hence the function foo must have two parameters:

  1. the object to lint

  2. the lint context

In foo the lint context can be used to add LintMessages to the lint context by using its valid, info, warn, and error functions:

lint_foo(target, lint_ctx):
    lint_ctx.error("target is screwed")

Calling lint prints out the messages emmited by the linter function immediately. Which messages are shown can be determined with the level argument of the LintContext constructor. If set to SILENT, no messages will be printed.

For special lint targets it might be useful to have additional information in the lint messages. This can be achieved by subclassing LintMessage. See for instance XMLLintMessageLine which has an additional argument node in its constructor which is used to determine the line and filename in an XML document that caused the message.

In order to use this.

  • the lint context needs to be initialized with the additional parameter lint_message_class=XMLLintMessageLine

  • the additional parameter needs to be added as well to calls adding messages to the lint context, e.g. lint_ctx.error("some message", node=X). Note that the additional properties must be given as keyword arguments.
