Module: BatchExperiment::FnameSanitizer

Defined in:
lib/batch_experiment.rb

Overview

The default callable object used by Comm2FnameConverter to convert a command into a filename. Comm2FnameConverter don’t create a sanitized filename from the command string (it uses its first argument to do this, whose default is FnameSanitizer). Note that this is a pure function, so if the same command appears more than one time, it will get the same name, it’s Comm2FnameConverter that gives multiple instances of the same command different names (by suffixing with numbers).
