Package lepl :: Package core :: Module trace

Module trace

Tools for logging and tracing.

Classes

_TraceResults
A basic logger (implemented as a monitor - MonitorInterface) that records the flow of control during parsing.

_RecordDeepest
A logger (implemented as a monitor - MonitorInterface) that records the deepest match found during a parse.

StreamMonitor
This prints (not logs) data about streams.

Functions

[hide private]

TraceResults(enabled=False)
A basic logger (implemented as a monitor - MonitorInterface) that records the flow of control during parsing. source code

RecordDeepest(n_before=6, n_results_after=2, n_done_after=2)

Function Details

[hide private]

TraceResults(enabled=False)

source code

A basic logger (implemented as a monitor - MonitorInterface) that records the flow of control during parsing. It can be controlled by Trace().

This is a factory that "escapes" the main class via a function to simplify configuration.

RecordDeepest(n_before=6, n_results_after=2, n_done_after=2)

source code

A logger (implemented as a monitor - MonitorInterface) that records the deepest match found during a parse.

This is a helper function that "escapes" the main class via a function to simplify configuration.
