-/* miniz.c 3.0.0 - 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).
-
-   * 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/inflateReset/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.
+static void _sqz_append (Sqz **squoze, Sqz *tail)
+{
+  if (!squoze) return;
+  Sqz *combined = sqz_cat (*squoze, tail);
+  sqz_unref (*squoze);
+  *squoze=combined;
+}
 
-     - Archive reading: Just call this function to read a single file from a disk archive:
+Sqz *sqz_substring (Sqz *a, int pos, int length)
+{
+  int src_length = sqz_length (a);
+  if (pos > src_length)
+    return sqz_utf8 ("");
+  if (pos < 0)
+    pos = src_length + pos + 1;
+  char tmp[16];
+  const char *src = sqz_decode (a, tmp);
+  char *end;
+  int allocated = 0;
 
-      void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name,
-        size_t *pSize, mz_uint zip_flags);
+  char *copy;
+  if (src_length < 256)
+  {
+    copy = alloca (strlen (src) + 1);
+    strcpy (copy, src);
+  }
+  else
+  {
+    copy  = strdup (src);
+    allocated = 1;
+  }
+  char *p = copy;
+  int i;
+  for (i = 0; i < pos; i++)
+    p += squoze_utf8_len (*p);
+  end = p;
+  for (i = 0; i < length && *end; i++)
+    end += squoze_utf8_len (*end);
+  *end = 0;
 
-     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.
+  Sqz *ret = sqz_utf8 (p);
+  if (allocated)
+    free (copy);
+  return ret;
+}
 
-     - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file:
+void sqz_erase (Sqz **a, int pos, int length)
+{
+  if (!a) return;
+  if (!*a) return;
 
-     int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags);
+  if (length < 1)
+    return;
+  if (pos < 0)
+  {
+    pos = sqz_length (*a) + pos;
+  }
 
-     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.
+  Sqz *pre  = sqz_substring (*a, 0, pos);
+  Sqz *post = sqz_substring (*a, pos+length, 10000);
+  sqz_unref (*a);
+  *a = sqz_cat (pre, post);
+  sqz_unref (pre);
+  sqz_unref (post);
+}
 
-     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().
+void sqz_insert (Sqz **a, int pos, Sqz *b)
+{
+  if (pos == 0)
+  {
+    _sqz_prepend (a, b);
+    return;
+  }
+  if (pos == -1)
+  {
+    _sqz_append (a, b);

-     - 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.
+  *a = sqz_cat (pre, b);
+  _sqz_append (a, post);
+  sqz_unref (pre);
+  sqz_unref (post);
+}
 
-     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.
+void sqz_insert_utf8 (Sqz **a, int pos, const char *utf8)
+{
+  Sqz *b = sqz_utf8 (utf8);
+  sqz_insert (a, pos, b);
+  sqz_unref (b);
+}
 
-     - Archive appending: The simple way to add a single file to an archive is to call this function:
+Sqz *sqz_unichar (uint32_t unichar)
+{
+  char temp[5];
+  temp[squoze_unichar_to_utf8 (unichar, (uint8_t*)temp)]=0;
+  return sqz_utf8 (temp);
+}
 
-      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);
+Sqz *sqz_int (int value)
+{
+  char temp[40];
+  sprintf (temp, "%i", value);
+  if (strchr (temp, ','))
+    *strchr (temp, ',')='.';
+  return sqz_utf8 (temp);
+}
 
-     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).
+Sqz *sqz_double (double value)
+{
+  char temp[40];
+  sprintf (temp, "%f", value);
+  if (strchr (temp, ','))
+    *strchr (temp, ',')='.';
+  return sqz_utf8 (temp);
+}
 
-     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.
+void sqz_insert_unichar (Sqz **a, int pos, uint32_t unichar)
+{
+  Sqz *b = sqz_unichar (unichar);
+  sqz_insert (a, pos, b);
+  sqz_unref (b);
+}
 
-     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.
+void sqz_insert_double (Sqz **a, int pos, double value)
+{
+  Sqz *b = sqz_double (value);
+  sqz_insert (a, pos, b);
+  sqz_unref (b);
+}
 
-     - ZIP archive support limitations:
-     No spanning support. Extraction functions can only handle unencrypted, stored or deflated files.
-     Requires streams capable of seeking.
+void sqz_insert_int (Sqz **a, int pos, int value)
+{
+  Sqz *b = sqz_int (value);
+  sqz_insert (a, pos, b);
+  sqz_unref (b);
+}
 
-   * 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.
+uint32_t sqz_unichar_at (Sqz *a, int pos)
+{
+  char tmp[16];
+  const char *str = sqz_decode (a, tmp);
+  const char *p = str;
+  int i;
+  if (pos < 0)
+  {
+    pos = sqz_length (a) + pos;
+  }
+  for (i = 0; i < pos; i++)
+    p += squoze_utf8_len (*p);
+  return squoze_utf8_to_unichar (p);
+}
 
-   * 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
+void sqz_replace (Sqz **a, int pos, int length, Sqz *b)
+{
+  sqz_erase (a, pos, length);
+  sqz_insert (a, pos, b);
+}
 
-   * 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).

+     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.
 
-#ifdef __cplusplus
-}
-#endif
+     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.
