Startle Library

Startle is a library of useful and efficient algorithms and facilities for developing C programs.

Library features include:

• Low overhead in-memory structured logging: deferred string formatting, indented with context, stored to a ring buffer, minimal overhead allowing use in release builds
• Macros: for common tasks such as iteration, bit/flag operations, intrusive lists
• Dispatch macros: Simulate overloaded functions for variable arguments
• Error handling
• Algorithms: Quicksort, binary search, string segments, simple mmap'ing, integer log, hash set
• Zero space overhead map: O(log(n)) insertion, O(log(n)^2) lookup, O(log(n)) in-place conversion to a sorted array for O(log(n)) lookup afterwards.

Makefile features include:

• Automatic dependency handling
• Integration with makeheaders to automatically generate and update headers for .c files
• Simple code generation: Collect macro-like annotations into lists for x-macros
  • Used for: Unit tests, handling commands and flags

Startle was originally developed as part of PoprC.
