  "github_readme_excerpt": "## AWS C Compression\n\nThis is a cross-platform C99 implementation of compression algorithms such as\ngzip, and huffman encoding/decoding. Currently only huffman is implemented.\n\n## License\n\nThis library is licensed under the Apache 2.0 License.\n\n## Usage\n\n### Building\n\nNote that aws-c-compression has a dependency on aws-c-common:\n\n```\ngit clone git@github.com:awslabs/aws-c-common.git\ncmake -DCMAKE_PREFIX_PATH=\u003cinstall-path\u003e -DCMAKE_INSTALL_PREFIX=\u003cinstall-path\u003e -S aws-c-common -B aws-c-common/build\ncmake --build aws-c-common/build --target install\n\ngit clone git@github.com:awslabs/aws-c-compression.git\ncmake -DCMAKE_PREFIX_PATH=\u003cinstall-path\u003e -DCMAKE_INSTALL_PREFIX=\u003cinstall-path\u003e -S aws-c-compression -B aws-c-compression/build\ncmake --build aws-c-compression/build --target install\n```\n\n### Huffman\n\nThe Huffman implemention in this library is designed around the concept of a\ngeneric \"symbol coder\" object, which defines how each symbol (value between 0\nand 255) is encoded and decoded. This object looks like this:\n```c\ntypedef struct aws_huffman_code (*aws_huffman_symbol_encoder)(uint8_t symbol, void *userdata);\ntypedef uint8_t (*aws_huffman_symbol_decoder)(uint32_t bits, uint8_t *symbol, void *userdata);\n\nstruct aws_huffman_symbol_coder {\n    aws_huffman_symbol_encoder encode;\n    aws_huffman_symbol_decoder decode;\n    void *userdata;\n};\n```\nThese callbacks may be implemented manually, or you may use the included\nHuffman coder generator to generate one from a table definition file. The\ngenerator expects to be called with the following arguments:\n```shell\n$ aws-c-compression-huffman-generator path/to/table.def path/to/generated.c coder_name\n```\n\nThe table definition file should be in the following format:\n```c\n/*           sym               bits   code len */\nHUFFMAN_CODE(  0,      \"1100101110\", 0x32e, 10)\nHUFFMAN_CODE(  1,      \"1100101111\", 0x32f, 10)\n/* ... */\n```\nThe HUFFMAN_CODE macro expects 4 arguments:\n* sym: the symbol value [0-255]\n* bits: the bits representin",
