class

pipda.utils.PipeableCallCheckWarning()

</>
Bases
Warning Exception BaseException

Warns when checking verb is called normally or using piping

class

pipda.utils.MultiImplementationsWarning()

</>
Bases
Warning Exception BaseException

Warns when multiple implementations are found

class

pipda.utils.PipeableCallCheckError()

</>
Bases
Exception BaseException

Raises when checking verb is called normally or using piping

class

pipda.utils.TypeHolder()

</>

A holder for a type that indicates the function passed toregister_verb or register_func is a placeholder (typically raising NotImplementedError), not a real implementation.

function

pipda.utils.update_user_wrapper(x, name, qualname, doc, module)

</>

Update the wrapper with user specified values

function

pipda.utils.is_piping(pipeable, fallback)

</>

Check if the pipeable is called with piping.

Example 
>>> data >> verb(...)>>> data >>= verb(...)
Parameters
  • pipeable (str) — The name of the verb, used in warning or exception messaging
  • fallback (str) — What if the AST node fails to retrieve?piping - Suppose this verb is called like data >> verb(...) normal - Suppose this verb is called like verb(data, ...) piping_warning - Suppose piping call, but show a warning normal_warning - Suppose normal call, but show a warning raise - Raise an error
Returns (bool)

True if it is a piping verb call, otherwise False

function

pipda.utils.evaluate_expr(expr, data, context) → any

</>

function

pipda.utils.has_expr(expr) → bool
