Utilities

Detailed Description

General-purpose utilities used across the TRIQS library.

The Utilities module collects foundational building blocks that the rest of the TRIQS library depends on: compiler glue and exception types, template-metaprogramming helpers, numerical helpers (Legendre, Chebyshev, Padé, ...), runtime utilities (timers, signal handling, crash logging) and a small set of I/O streams.

The utilities are organised into the following thematic subgroups:

• I/O streams — reporting and debugging output streams,
• Macros and exceptions — foundational macros, exception types and compiler/platform glue,
• Math helpers — numerical and mathematical helpers,
• Other utilities — other general-purpose utilities,
• Runtime utilities — timers, signal handling and other runtime utilities,
• Tuple and variant tools — helpers for manipulating and serializing tuples and variants,
• Type traits and metaprogramming — type traits and template-metaprogramming helpers.

Most utilities live in the triqs::utility namespace.
