    SimpleXlsxWriter

    C++ library for creating XLSX files for MS Excel 2007 and above.

    This library represents XLSX files writer for Microsoft Excel 2007 and above. The main feature of this library is that it uses C++ standard file streams. On the one hand it results in almost unnoticeable memory and CPU resources consumption while processing (that may be very useful at saving a large data arrays), but on the other hand it makes unfeasible to edit data that were written. Hence, if using this library the structure of the future report should be known enough. ...

    Table Maker for Modern C++

    tabulate is a header-only library. Just add include/ to your include_directories and you should be good to go. A single header file version is also available in single_include/. Although word-wrapping is automatic, there is a simple override. Automatic word-wrapping is used only if the cell contents do not have any embedded newline \n characters. So, you can embed newline characters in the cell contents and enforce the word-wrapping manually. tabulate allows for fine control over borders and...

    Moelnir

    Moelnir

    Heap organised database service (Java library)

    Moelnir is a basic database file, addressing variable record data through integer identifiers, which applies heap organisation of its data space. Advantage of Moelnir is that each record is stored in a continuous segment on the file while still record size is limit-less variable and modifiable. There are no data length limits other than the range of a 63-bit unsigned integer. Scalability is limited to 1 - 10 Mio. entries due to non-paging internal structures.

    CityHash

    CityHash

    Automatically exported from Google code CityHash

    CityHash is a family of non-cryptographic hash functions optimized for extremely fast and high-quality hashing of strings on modern CPUs. Developed by Google, it is implemented in C++ and designed to efficiently handle both short and long inputs using techniques such as mixing operations and CPU-specific optimizations. CityHash offers multiple hash sizes—32-bit, 64-bit, 128-bit, and 256-bit variants—with the CRC-based versions leveraging hardware acceleration on CPUs that support SSE4.2 CRC32 instructions. The library emphasizes hashing performance and uniformity rather than cryptographic security, making it ideal for use in data structures like hash tables and distributed systems requiring rapid key lookups. ...
