+### A portable (OSX/Linux/Windows), simple zip library written in C
+This is done by hacking awesome [miniz](https://code.google.com/p/miniz) library and layering functions on top of the miniz v1.15 API.
+
+[![Build](https://github.com/kuba--/zip/workflows/build/badge.svg)](https://github.com/kuba--/zip/actions?query=workflow%3Abuild)
+
+
+# The Idea
+<img src="zip.png" name="zip" />
+... Some day, I was looking for zip library written in C for my project, but I could not find anything simple enough and lightweight.
+Everything what I tried required 'crazy mental gymnastics' to integrate or had some limitations or was too heavy.
+I hate frameworks, factories and adding new dependencies. If I must to install all those dependencies and link new library, I'm getting almost sick.
+I wanted something powerfull and small enough, so I could add just a few files and compile them into my project.
+And finally I found miniz.
+Miniz is a lossless, high performance data compression library in a single source file. I only needed simple interface to append buffers or files to the current zip-entry. Thanks to this feature I'm able to merge many files/buffers and compress them on-the-fly.
+
+It was the reason, why I decided to write zip module on top of the miniz. It required a little bit hacking and wrapping some functions, but I kept simplicity. So, you can grab these 3 files and compile them into your project. I hope that interface is also extremely simple, so you will not have any problems to understand it.
+
+# Examples
+
+* Create a new zip archive with default compression level.
+```c
+struct zip_t *zip = zip_open("foo.zip", ZIP_DEFAULT_COMPRESSION_LEVEL, 'w');
+{
+    zip_entry_open(zip, "foo-1.txt");
+    {
+        const char *buf = "Some data here...\0";
+        zip_entry_write(zip, buf, strlen(buf));
+    }
+    zip_entry_close(zip);
+
+    zip_entry_open(zip, "foo-2.txt");
+    {
+        // merge 3 files into one entry and compress them on-the-fly.
+        zip_entry_fwrite(zip, "foo-2.1.txt");
+        zip_entry_fwrite(zip, "foo-2.2.txt");
+        zip_entry_fwrite(zip, "foo-2.3.txt");
+    }
+    zip_entry_close(zip);
+}
+zip_close(zip);
+```
+
+* Append to the existing zip archive.
+```c
+struct zip_t *zip = zip_open("foo.zip", ZIP_DEFAULT_COMPRESSION_LEVEL, 'a');
+{
+    zip_entry_open(zip, "foo-3.txt");
+    {
+        const char *buf = "Append some data here...\0";
+        zip_entry_write(zip, buf, strlen(buf));
+    }
+    zip_entry_close(zip);
+}
+zip_close(zip);
+```
+
+* Extract a zip archive into a folder.
+```c
+int on_extract_entry(const char *filename, void *arg) {
+    static int i = 0;
+    int n = *(int *)arg;
+    printf("Extracted: %s (%d of %d)\n", filename, ++i, n);
+
+    return 0;
+}
+
+int arg = 2;
+zip_extract("foo.zip", "/tmp", on_extract_entry, &arg);
+```
+
+* Extract a zip entry into memory.
+```c
+void *buf = NULL;
+size_t bufsize;
+
+struct zip_t *zip = zip_open("foo.zip", 0, 'r');
+{
+    zip_entry_open(zip, "foo-1.txt");
+    {
+        zip_entry_read(zip, &buf, &bufsize);
+    }
+    zip_entry_close(zip);
+}
+zip_close(zip);
+
+free(buf);
+```
+
+* Extract a zip entry into memory (no internal allocation).
+```c
+unsigned char *buf;
+size_t bufsize;
+
+struct zip_t *zip = zip_open("foo.zip", 0, 'r');
+{
+    zip_entry_open(zip, "foo-1.txt");
+    {
+        bufsize = zip_entry_size(zip);
+        buf = calloc(sizeof(unsigned char), bufsize);
+
+        zip_entry_noallocread(zip, (void *)buf, bufsize);
+    }
+    zip_entry_close(zip);
+}
+zip_close(zip);
+
+free(buf);
+```
+
+* Extract a zip entry into memory using callback.
+```c
+struct buffer_t {
+    char *data;
+    size_t size;
+};
+
+static size_t on_extract(void *arg, unsigned long long offset, const void *data, size_t size) {
+    struct buffer_t *buf = (struct buffer_t *)arg;
+    buf->data = realloc(buf->data, buf->size + size + 1);
+    assert(NULL != buf->data);
+
+    memcpy(&(buf->data[buf->size]), data, size);
+    buf->size += size;
+    buf->data[buf->size] = 0;
+
+    return size;
+}
+
+struct buffer_t buf = {0};
+struct zip_t *zip = zip_open("foo.zip", 0, 'r');
+{
+    zip_entry_open(zip, "foo-1.txt");
+    {
+        zip_entry_extract(zip, on_extract, &buf);
+    }
+    zip_entry_close(zip);
+}
+zip_close(zip);
+
+free(buf.data);
+```
+
+
+* Extract a zip entry into a file.
+```c
+struct zip_t *zip = zip_open("foo.zip", 0, 'r');
+{
+    zip_entry_open(zip, "foo-2.txt");
+    {
+        zip_entry_fread(zip, "foo-2.txt");
+    }
+    zip_entry_close(zip);
+}
+zip_close(zip);
+```
+
+* Create a new zip archive in memory (stream API).
+
+```c
+char *outbuf = NULL;
+size_t outbufsize = 0;
+
+const char *inbuf = "Append some data here...\0";
+struct zip_t *zip = zip_stream_open(NULL, 0, ZIP_DEFAULT_COMPRESSION_LEVEL, 'w');
+{
+    zip_entry_open(zip, "foo-1.txt");
+    {
+        zip_entry_write(zip, inbuf, strlen(inbuf));
+    }
+    zip_entry_close(zip);
+
+    /* copy compressed stream into outbuf */
+    zip_stream_copy(zip, (void **)&outbuf, &outbufsize);
+}
+zip_stream_close(zip);
+
+free(outbuf);
+```
+
+* Extract a zip entry into a memory (stream API).
+
+```c
+char *buf = NULL;
+ssize_t bufsize = 0;
+
+struct zip_t *zip = zip_stream_open(zipstream, zipstreamsize, 0, 'r');
+{
+    zip_entry_open(zip, "foo-1.txt");
+    {
+        zip_entry_read(zip, (void **)&buf, &bufsize);
+    }
+    zip_entry_close(zip);
+}
+zip_stream_close(zip);
+
+free(buf);
+```
+
+* List of all zip entries
+```c
+struct zip_t *zip = zip_open("foo.zip", 0, 'r');
+int i, n = zip_entries_total(zip);
+for (i = 0; i < n; ++i) {
+    zip_entry_openbyindex(zip, i);
+    {
+        const char *name = zip_entry_name(zip);
+        int isdir = zip_entry_isdir(zip);
+        unsigned long long size = zip_entry_size(zip);
+        unsigned int crc32 = zip_entry_crc32(zip);
+    }
+    zip_entry_close(zip);
+}
+zip_close(zip);
+```
+
+* Compress folder (recursively)
+```c
+void zip_walk(struct zip_t *zip, const char *path) {
+    DIR *dir;
+    struct dirent *entry;
+    char fullpath[MAX_PATH];
+    struct stat s;
+
+    memset(fullpath, 0, MAX_PATH);
+    dir = opendir(path);
+    assert(dir);
+
+    while ((entry = readdir(dir))) {
+      // skip "." and ".."
+      if (!strcmp(entry->d_name, ".\0") || !strcmp(entry->d_name, "..\0"))
+        continue;
+
+      snprintf(fullpath, sizeof(fullpath), "%s/%s", path, entry->d_name);
+      stat(fullpath, &s);
+      if (S_ISDIR(s.st_mode))
+        zip_walk(zip, fullpath);
+      else {
+        zip_entry_open(zip, fullpath);
+        zip_entry_fwrite(zip, fullpath);
+        zip_entry_close(zip);
+      }
+    }
+
+    closedir(dir);
+}
+```
+
+* Deletes zip archive entries.
+```c
+char *entries[] = {"unused.txt", "remove.ini", "delete.me"};
+
+struct zip_t *zip = zip_open("foo.zip", 0, 'd');
+{
+    zip_entries_delete(zip, entries, 3);
+}
+zip_close(zip);
+```

+   miniz.c v1.15 - public domain deflate/inflate, zlib-subset, ZIP
+   reading/writing/appending, PNG writing See "unlicense" statement at the end
+   of this file. Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13,
+   2013 Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951:
+   http://www.ietf.org/rfc/rfc1951.txt
+
+   Most API's defined in miniz.c are optional. For example, to disable the
+   archive related functions just define MINIZ_NO_ARCHIVE_APIS, or to get rid of
+   all stdio usage define MINIZ_NO_STDIO (see the list below for more macros).
+
+   * Change History
+     10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major
+   release with Zip64 support (almost there!):
+       - Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug
+   (thanks kahmyong.moon@hp.com) which could cause locate files to not find
+   files. This bug would only have occured in earlier versions if you explicitly
+   used this flag, OR if you used mz_zip_extract_archive_file_to_heap() or
+   mz_zip_add_mem_to_archive_file_in_place() (which used this flag). If you
+   can't switch to v1.15 but want to fix this bug, just remove the uses of this
+   flag from both helper funcs (and of course don't use the flag).
+       - Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when
+   pUser_read_buf is not NULL and compressed size is > uncompressed size
+       - Fixing mz_zip_reader_extract_*() funcs so they don't try to extract
+   compressed data from directory entries, to account for weird zipfiles which
+   contain zero-size compressed data on dir entries. Hopefully this fix won't
+   cause any issues on weird zip archives, because it assumes the low 16-bits of
+   zip external attributes are DOS attributes (which I believe they always are
+   in practice).
+       - Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the
+   internal attributes, just the filename and external attributes
+       - mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
+       - Added cmake support for Linux builds which builds all the examples,
+   tested with clang v3.3 and gcc v4.6.
+       - Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
+       - Merged MZ_FORCEINLINE fix from hdeanclark
+       - Fix <time.h> include before config #ifdef, thanks emil.brink
+       - Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping
+   (super useful for OpenGL apps), and explicit control over the compression
+   level (so you can set it to 1 for real-time compression).
+       - Merged in some compiler fixes from paulharris's github repro.
+       - Retested this build under Windows (VS 2010, including static analysis),
+   tcc  0.9.26, gcc v4.6 and clang v3.3.
+       - Added example6.c, which dumps an image of the mandelbrot set to a PNG
+   file.
+       - Modified example2 to help test the
+   MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
+       - In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix
+   possible src file fclose() leak if alignment bytes+local header file write
+   faiiled
+   - In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader(): Was pushing the
+   wrong central dir header offset, appears harmless in this release, but it
+   became a problem in the zip64 branch 5/20/12 v1.14 - MinGW32/64 GCC 4.6.1
+   compiler fixes: added MZ_FORCEINLINE, #include <time.h> (thanks fermtect).
+     5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix
+   mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
+       - Temporarily/locally slammed in "typedef unsigned long mz_ulong" and
+   re-ran a randomized regression test on ~500k files.
+       - Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
+       - Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze
+   (static analysis) option and fixed all warnings (except for the silly "Use of
+   the comma-operator in a tested expression.." analysis warning, which I
+   purposely use to work around a MSVC compiler warning).
+       - Created 32-bit and 64-bit Codeblocks projects/workspace. Built and
+   tested Linux executables. The codeblocks workspace is compatible with
+   Linux+Win32/x64.
+       - Added miniz_tester solution/project, which is a useful little app
+   derived from LZHAM's tester app that I use as part of the regression test.
+       - Ran miniz.c and tinfl.c through another series of regression testing on
+   ~500,000 files and archives.
+       - Modified example5.c so it purposely disables a bunch of high-level
+   functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the
+   MINIZ_NO_STDIO bug report.)
+       - Fix ftell() usage in examples so they exit with an error on files which
+   are too large (a limitation of the examples, not miniz itself). 4/12/12 v1.12
+   - More comments, added low-level example5.c, fixed a couple minor
+   level_and_flags issues in the archive API's. level_and_flags can now be set
+   to MZ_DEFAULT_COMPRESSION. Thanks to Bruce Dawson <bruced@valvesoftware.com>
+   for the feedback/bug report. 5/28/11 v1.11 - Added statement from
+   unlicense.org 5/27/11 v1.10 - Substantial compressor optimizations:
+      - Level 1 is now ~4x faster than before. The L1 compressor's throughput
+   now varies between 70-110MB/sec. on a
+      - Core i7 (actual throughput varies depending on the type of data, and x64
+   vs. x86).
+      - Improved baseline L2-L9 compression perf. Also, greatly improved
+   compression perf. issues on some file types.
+      - Refactored the compression code for better readability and
+   maintainability.
+      - Added level 10 compression level (L10 has slightly better ratio than
+   level 9, but could have a potentially large drop in throughput on some
+   files). 5/15/11 v1.09 - Initial stable release.
+
+   * Low-level Deflate/Inflate implementation notes:
+
+     Compression: Use the "tdefl" API's. The compressor supports raw, static,
+   and dynamic blocks, lazy or greedy parsing, match length filtering, RLE-only,
+   and Huffman-only streams. It performs and compresses approximately as well as
+   zlib.
+
+     Decompression: Use the "tinfl" API's. The entire decompressor is
+   implemented as a single function coroutine: see tinfl_decompress(). It
+   supports decompression into a 32KB (or larger power of 2) wrapping buffer, or
+   into a memory block large enough to hold the entire file.
+
+     The low-level tdefl/tinfl API's do not make any use of dynamic memory
+   allocation.
+
+   * zlib-style API notes:
+
+     miniz.c implements a fairly large subset of zlib. There's enough
+   functionality present for it to be a drop-in zlib replacement in many apps:
+        The z_stream struct, optional memory allocation callbacks
+        deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
+        inflateInit/inflateInit2/inflate/inflateEnd
+        compress, compress2, compressBound, uncompress
+        CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly
+   routines. Supports raw deflate streams or standard zlib streams with adler-32
+   checking.
+
+     Limitations:
+      The callback API's are not implemented yet. No support for gzip headers or
+   zlib static dictionaries. I've tried to closely emulate zlib's various
+   flavors of stream flushing and return status codes, but there are no
+   guarantees that miniz.c pulls this off perfectly.
+
+   * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function,
+   originally written by Alex Evans. Supports 1-4 bytes/pixel images.
+
+   * ZIP archive API notes:
+
+     The ZIP archive API's where designed with simplicity and efficiency in
+   mind, with just enough abstraction to get the job done with minimal fuss.
+   There are simple API's to retrieve file information, read files from existing
+   archives, create new archives, append new files to existing archives, or
+   clone archive data from one archive to another. It supports archives located
+   in memory or the heap, on disk (using stdio.h), or you can specify custom
+   file read/write callbacks.
+
+     - Archive reading: Just call this function to read a single file from a
+   disk archive:
+
+      void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const
+   char *pArchive_name, size_t *pSize, mz_uint zip_flags);
+
+     For more complex cases, use the "mz_zip_reader" functions. Upon opening an
+   archive, the entire central directory is located and read as-is into memory,
+   and subsequent file access only occurs when reading individual files.
+
+     - Archives file scanning: The simple way is to use this function to scan a
+   loaded archive for a specific file:
+
+     int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName,
+   const char *pComment, mz_uint flags);
+
+     The locate operation can optionally check file comments too, which (as one
+   example) can be used to identify multiple versions of the same file in an
+   archive. This function uses a simple linear search through the central
+     directory, so it's not very fast.
+
+     Alternately, you can iterate through all the files in an archive (using
+   mz_zip_reader_get_num_files()) and retrieve detailed info on each file by
+   calling mz_zip_reader_file_stat().
+
+     - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer
+   immediately writes compressed file data to disk and builds an exact image of
+   the central directory in memory. The central directory image is written all
+   at once at the end of the archive file when the archive is finalized.
+
+     The archive writer can optionally align each file's local header and file
+   data to any power of 2 alignment, which can be useful when the archive will
+   be read from optical media. Also, the writer supports placing arbitrary data
+   blobs at the very beginning of ZIP archives. Archives written using either
+   feature are still readable by any ZIP tool.
+
+     - Archive appending: The simple way to add a single file to an archive is
+   to call this function:
+
+      mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename,
+   const char *pArchive_name, const void *pBuf, size_t buf_size, const void
+   *pComment, mz_uint16 comment_size, mz_uint level_and_flags);
+
+     The archive will be created if it doesn't already exist, otherwise it'll be
+   appended to. Note the appending is done in-place and is not an atomic
+   operation, so if something goes wrong during the operation it's possible the
+   archive could be left without a central directory (although the local file
+   headers and file data will be fine, so the archive will be recoverable).
+
+     For more complex archive modification scenarios:
+     1. The safest way is to use a mz_zip_reader to read the existing archive,
+   cloning only those bits you want to preserve into a new archive using using
+   the mz_zip_writer_add_from_zip_reader() function (which compiles the
+     compressed file data as-is). When you're done, delete the old archive and
+   rename the newly written archive, and you're done. This is safe but requires
+   a bunch of temporary disk space or heap memory.
+
+     2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using
+   mz_zip_writer_init_from_reader(), append new files as needed, then finalize
+   the archive which will write an updated central directory to the original
+   archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place()
+   does.) There's a possibility that the archive's central directory could be
+   lost with this method if anything goes wrong, though.
+
+     - ZIP archive support limitations:
+     No zip64 or spanning support. Extraction functions can only handle
+   unencrypted, stored or deflated files. Requires streams capable of seeking.
+
+   * This is a header file library, like stb_image.c. To get only a header file,
+   either cut and paste the below header, or create miniz.h, #define
+   MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it.
+
+   * Important: For best perf. be sure to customize the below macros for your
+   target platform: #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 #define
+   MINIZ_LITTLE_ENDIAN 1 #define MINIZ_HAS_64BIT_REGISTERS 1
+
+   * On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before
+   including miniz.c to ensure miniz uses the 64-bit variants: fopen64(),
+   stat64(), etc. Otherwise you won't be able to process large files (i.e.
+   32-bit stat() fails for me on files > 0x7FFFFFFF bytes).
