Detailed Description

Handle errors in the whole project.

Each task has an error status depending on its exit code described in the enum below.

Several versions of operator<< are used to fill the handler.

A global variable is defined to centralize all the error uses.

Member Typedef Documentation

typedef void(error::* misc::error::const_member_manip_type)() const

Enumerator:

success	Job successfully done.
failure	Some unspecified error happened.
scan	Lexical error.
parse	Syntactic error.
bind	Binding error: undefined name.
type	Type checking error.
