Klib is a standalone, lightweight C library of generic data structures and algorithms implemented largely as single-header files using C macros. It includes efficient hash tables, B-trees, AVL trees, sorting routines, dynamic arrays, string utilities, and bioinformatics parsers like FASTA/FASTQ.

Use cases

• add a fast hash table to a C project without dependencies
• sort large arrays efficiently in C
• parse FASTA/FASTQ bioinformatics files
• implement a B-tree or AVL tree in C
• parse command-line arguments in a portable C program
• build a dynamic array or linked list with minimal overhead

When to choose

• you need high-performance generic containers in C with minimal footprint
• you want copy-paste single-file components with no library dependencies
• you are writing performance-critical or bioinformatics C code

When to avoid

• you prefer clean, template-free APIs over macro-heavy code
• you need a full-featured container library like Glib with rich utilities
• you are working in a language other than C
