### 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.

# 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");
{
char *buf = "Some data here...";
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");
{
char *buf = "Append some data here...";
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 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);
```
