twisted.logger._format : API documentation

Function	formatUnformattableEvent	Formats an event as a `unicode` that describes the event generically and a formatting error.
Class	CallMapping	Read-only mapping that turns a `()`-suffix in key names into an invocation of the key rather than a lookup of the key.
Function	formatWithCall	Format a string like `unicode.format`, but:

def formatUnformattableEvent(event, error): (source)

Formats an event as a unicode that describes the event generically and a formatting error.

Parameters	event	A logging event. (type: `dict`)
	error	The formatting error. (type: `Exception`)
Returns	A formatted string. (type: `unicode`)

def formatWithCall(formatString, mapping): (source)

Format a string like unicode.format, but:

taking only a name mapping; no positional arguments
with the additional syntax that an empty set of parentheses correspond to a formatting item that should be called, and its result str'd, rather than calling str on the element directly as normal.

For example:

   >>> formatWithCall("{string}, {function()}.",
   ...                dict(string="just a string",
   ...                     function=lambda: "a function"))
   'just a string, a function.'

Parameters	formatString	A PEP-3101 format string. (type: `unicode`)
	mapping	A `dict`-like object to format.
Returns	The string with formatted values interpolated. (type: `unicode`)
