    FlatCC FlatBuffers in C for C

    FlatCC FlatBuffers in C for C

    FlatBuffers Compiler and Library in C for C

    flatcc has no external dependencies except for build and compiler tools, and the C runtime library. With concurrent Ninja builds, a small client project can build flatcc with libraries, generate schema code, link the project and execute a test case in a few seconds, produce binaries between 15K and 60K, read small buffers in 30ns, build FlatBuffers in about 600ns, and with a larger executable also handle optional json parsing or printing in less than 2 us for a 10 field mixed type message. The JSON parser may change the interface for parsing union vectors in a future release which requires code generation to match library versions. This project builds flatcc, a compiler that generates FlatBuffers code for C given a FlatBuffer schema file. This introduction also creates a separate test project with the traditional monster example, here in a C version. The setup script builds flatcc using CMake, then creates a test project directory with the monster example.

    XLSX I/O

    C library for reading/writing values from/to Excel .xlsx files.

    Cross-platform C library for reading values from and writing values to .xlsx files. XLSX I/O aims to provide a C library for reading and writing .xlsx files. The .xlsx file format is the native format used by Microsoft(R) Excel(TM) since version 2007. The library was written with the following goals in mind: - primary focus on data values organized in tables, on not layout or graphics - written in standard C, but allows being used by C++ - simple interface - small footprint - portable across different platforms (Windows, *nix) - minimal dependancies: only depends on expat (only for reading) and libzip (which in turn depends on zlib) - separate library for reading and writing .xlsx files Also includes command line tools to convert between .xslx and CSV files.

    gawk libraries for XML, PostgreSQL,...

    Dynamically loaded extension libraries for GNU AWK

    The gawkextlib project provides several extension libraries for gawk (GNU AWK), as well as libgawkextlib containing some APIs that are useful for building gawk extension libraries. These libraries enable gawk to process XML data, interact with a PostgreSQL database, use the GD graphics library, and perform unlimited precision MPFR calculations. These extensions work with GNU AWK version 4.1.1 or later. We have created a framework for packaging gawk extensions, and we welcome further contributions. Recent additions include haru, redis, and select for I/O multiplexing.

    shadowsocks-libev

    shadowsocks-libev

    Bug-fix-only libev port of shadowsocks

    Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy.
